Lupine Publishers | The Role of Rubber Dam in Preventing Coronavirus Diseases 2019 (Covid-19) in Dentistry

 Lupine Publishers | Journal of Pediatric Dentistry

Letter to Editor

The concept of dental dam or rubber dam was first developed by Barnum in 1864. He reported struggling with saliva contamination during treatment for a long time. On one occasion, while he was treating a mandibular molar and saliva was flowing all over the oral cavity, he came up with a new idea, making a hole in his protective napkin and putting it around the tooth. This idea resulted in developing rubber dam, the main problem of which was not being fixed around the tooth. To address this problem, rubber dam punches, a set of metal clamps, and other equipment of rubber dam were introduced in the following years [1]. Rubber dam is a thin, 15 cm square disposable rubber sheet, which is of two types: latex and non-latex (nitrile). In dentistry, rubber dam is used for the isolation of the operative site from the oral cavity in order to increase the safety and quality of dental procedures. Rubber dam prevents the patient from aspiration or swallowing dental instruments as well as cross infection and contaminated aerosols [2]. This brief letter focused on the role of rubber dam against transmission of contaminated aerosols, particularly COVID-19.
Dental aerosol or splatter is produced from dental instruments, such as ultrasonic scalers or dental handpieces. Aerosol is a particle less than 50 μm in diameter and has the potential to stay airborne for a long period before it settles on surrounding surfaces or gets into the respiratory tract. Aerosol droplets which are >0.5-10 μm have an improved ability to transmit severe acute respiratory syndrome. Particles larger than 50 μm are defined as splatter and are airborne only for a short period. With that being said, almost 99% of airborne particles can be eliminated through the use of a high-volume evacuator during treatment [3].
According to the World Health Organization (WHO), viral epidemics are a serious threat to public health. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) first appeared in the city of Wuhan, in December 2019. On February 11, 2020, WHO named the virus, coronavirus diseases 2019 (COVID-19). COVID-19 leads to severe respiratory problems and in some cases even death. It is transmitted through contaminated aerosol droplets >5-10 μm from coughing or sneezing. Thus, close contact (within 1 m) with an infected person causes the mucosa, oral or nasal cavity, and conjunctiva to be exposed to respiratory droplets containing coronavirus infection [4]. Since dental health care providers are constantly in close proximity to patients, they are at risk of microbial or viral infection that can be transmitted through atmospheric aerosols.
In a study conducted by Samaranayake et al. [5] the effectiveness of the rubber dam in preventing contaminated aerosols during therapy was examined. The result demonstrated that the rubber dam significantly reduces the contaminated aerosol particles from the operational site up to 3-foot distance (91,44 cm) by 70%. Moreover, the use of rubber dam decreases the production of saliva and blood contamination during dental treatment as well as the potential airborne particles between the clinician and patient [3]. In addition, in the case in which the gingival is exposed, the split-dam method is useful. According to the evidence provided, it is possible that the use of rubber dam contributes to the prevention of COVID-19. However, conducting more clinical or laboratory studies investigating the role of rubber dam against respiratory diseases, particularly COVID-19 is recommended in order to obtain more accurate and valid data.\

Lupine Publishers | Electric Pulp Testing in Children During Permanent Teeth Apexes Formation

 Lupine Publishers | Journal of Pediatric Dentistry


Mini Review

Pain sensation is evolutionarily the primary basis of sensitive human activity, and it is quite stable. The stability of electrodontometry (EOM) indicators is demonstrated by a narrow zone of the pain threshold of 2-6 mkA of healthy front teeth, which was first evaluated by Rubin L. R. in 1953. This value was confirmed by many domestic researchers [1,2]. Rubin tried to extend it to all teeth, but the indicators of the lateral teeth, although stable, are 5-15 mkA higher [3-5]. The most important feature of the sensitivity of the dental pulp is that it is represented by an exceptional pain [6,7]. Its sensitivity is very high -2-6 mkA- and sharply differs from the sensitivity of the skin and all surrounding tissues, including the gums and periapical tissues. It is located at the level of 100-200 mkA. The pulp, perceiving tactile, thermal and electrical irritation, translates it into a painful sensation. In the human tooth, the circulatory and nervous systems of the pulp are separated as a thin soft string and are protected from external influences by a thick tube of enamel and dentin. The nerves in the pulp are 20.5% by weight.The pulp is represented by two main pain points that determine pain sensitivity. In the crown pulp, these are odontoblasts and dentine tubes with 1-2 mm of nerve branches of A-Delta fibers entering them. At the root it is a narrow thin apical part of the canal, where the pulpar nerves of the pulp core from C- fibers are tightly placed together with the blood vessels. Secondary cement is also involved in creating the apical opening, preventing myelination of the nerve tissue there[8]. The presence of myelin A-Delta fibers in the apex has not been proven. Pain fibers A-Delta are slightly myelinated, located in the crown, have a higher rate of conduction (dentin pain). They respond to the pulse current as an acute pain sensation. C-fibers transmit late, dull and not always clear pulp pain. It is interesting that all foreign authors use A-Delta fibers [6], to consider themechanisms of electrodontometry (EOM) from the standpoint of the theory of Branstrom, with an emphasis on EPT (Electrical pulpal test) as dentin stimulation. Foreign researchers exclude the reaction of pain by C-fibers, which make up the bulk of the nerve structures of the tooth.
Interestingly, EPT is rated as a low-value test for primary or permanent teeth during apex formation [9].Many children with normal teeth do not respond even to high stimulation currents [9].We believe that for the reaction of all neuroreceptors in single teeth, a more universal AC stimulator with a broad total effect, mainly on C-fibers, is needed.The aim of our investigation was: to evaluate tooth maturation in children aged 6.5 - 15 years in dynamics in the study of pain caused by electrotesting in three directions:
a) Reduction of the pain threshold of the central incisors,
b) x-ray width of the apex, and
c) The nature of the pain: pain or not pain.

Material and Methods

280 teeth were examined in 280 children from 6 to 15 years (central incisors). Patients were divided by age into 5 groups:1 - 6,5 – 7 years; 2 – 7-8 years; 3 – 9-10 years; 4 11-12 years; 5 – 13-15 years.After receiving informed consent, the oral cavity was examined, the child was instructed, and the central incisors were isolated from saliva. The threshold of pain sensitivity of the dental pulp was determined using the IVN-01 Pulpotest-Pro electrodontodiagnostic device. Measurements were made on the central upper incisor. The pulp tester used created a series of alternating current pulses, devoid of polarization, with a frequency of 50 Hz with a gradually increasing current strength on a scale from 0 to 200 mkA until the first sensation: pain/non-pain[10-15]. The active electrode was located in a PVC tube into which the contact gel was inserted. The diameter of the active electrode was 4 mm. The passive metal electrode was in the hand of the subject. When pain occurred, the subject released the button, thus stopping the current supply, and the value of the EOM was recorded on the display. Indications of the pain threshold after a two-time (one- time) measurement were recorded.In addition to the digital indicator of EOM, the response to electrical stimulation was determined. The main criterion for pain was to divide it into pain / non-pain. All patients according to indications, as a rule, aesthetic, carried out radiography. Intraoral and x-ray images were used to measure the diameter of the tooth apex in mm[16-18].

Results

The results are shown in Table 1. Figure 1 shows a descending curve similar for all three parameters under study: EOM, apex, and pain.The highest EOM index was observed in the first age group (140.86 mkA), exceeding that in the second age group by more than 1.5 times (91.95 mkA). At the same time, the average diameter of the apex decreased from 2.55 to 1.96 mm. For both parameters, the differences between the first and second age groups were statistically significant (t-criteria 5.70 and 6.8, respectively). Between the second and third age groups, the difference in EOM indicators was sharper— 91.95 mkA to 39.75 mkA-with almost the same smooth decrease in the diameter of the apical opening (1.96 to 1.39 mm). For both parameters, the differences between the second and third age groups were statistically significant (criterion t = 7.48 and 8.90). Indicators of EOM in the third and fourth age groups differed a little, although the average value of EOM in the fourth group is slightly lower: 35.83 mkA compared to 39.75 mkA (the differences were not statistically significant, the criterion t = 0.70, and the diameter of the apex was significantly different: 0.82 mm compared to 1.39 mm (criterion t = 11.40). In the fourth and fifth age groups, the EOM as well as the apex diameter differed significantly, but without a sharp decrease in these indicators: from 35.83 to 24.35 mkA and from 0.82 to 0.72 mm (criterion t = 2.21 and 2.36, respectively). A sharp drop in EOM indicators occurred at the age of 6.5 to 11 years with a furthermore gradual decline (Figure 1).In the first age group, 13 subjects had no pain at all, and 6 (38%) subjects had a pre-pain sensation that was close to tactile. In the second group, 4 children had no pain, and 5 had afeeling of pre-pain in the form of cold or heat with spreading in the gum above the tooth (14.5%). In the group of 9-10 years, 4 subjects had a feeling of pre-pain (7.14%), in 11-12 years in 5%, in 13-15 years in 1.92%(Figure 2).

Pain is one of the main feelings. With age, the senses improve. The difference in pain assessment is visible on the graph (Figure 1). The youngest ones have the greatest feeling of “non- pain”. Children replaced real pain with feelings of cold, heat, etc. We have combined these feelings into the concept of pre-pain.Pain sensitivity of a permanent tooth is the main pain criterion of a person, in which, unlike animals, there is contact with the researcher. The phenomenon of a sharp decrease in the sensitivity of permanent teeth that are in the process of eruption has been established. A close relationship has been established between the reaction of A-Delta fibers and pulsed diagnostic current. The role of C-fibers – the basis of the tooth’s nervous system-is underestimated. The electric current due to its strength and the large electrode covers the entire pulp, both coronal and apical (Figure 3). In our literature, there is a tendency to prohibit devices that operate from alternating sinusoidal current with a frequency of 50 Hz [1,2]. The regularities between the degree of tooth eruption and the reduction of its pain threshold to a minimum level, while reducing the apical narrowing, and clarifying the pain response in a young subject were determined. The formation of the apex consists in its gradual narrowing, including ingrowth of cement into the apical part of the root canal. It is dominated by C-fibers. Pulse pulp testers do not “feel” the pulp in the erupting teeth.It should be noted that when the final apex was formed, the threshold value did not always correspond to the previously accepted norm of 2-6 mkA. In one 15-year-old patient, the initial pain threshold was 125 mkA.

Conclusions

The phenomenon of reducing the pain sensitivity of permanent teeth during eruption due to the reaction of C-fibers has been established. Pulse pulp testers do not work in teeth during apex formation.

Lupine Publishers | Children’s Perception About Dental Care in Patients Attended at Ceulp-Ulbra School Clinic

 Lupine Publishers | Journal of Pediatric Dentistry


Abstract

The dental care of children is an area that requires special attention. The dental visit, even in the early years of life, allows the child to have, early on, greater contact and familiarity with the dental environment, thus having the possibility to learn new habits in addition to positive experiences with regard to oral health. Thus, it is extremely important to know the view of children about the dental care provided by the institution CEUPL-ULBRA. We randomly selected children aged 3 to 11 years, 13 males and 8 females. Data collection was performed through interviews and story-design after the service, as well as analysis of the medical records to record the procedures performed. For the analysis of the drawings and for the interview, four categories were considered:
a) Dental environment
b) Dental treatment
c) Dentist image and
d) Behavioral manifestation
The most frequent categories in storytelling were the environment and dental treatment, with the most cited curative procedures. The operator / dentist’s image according to the drawing was considered technical. According to the interview, the clinical procedure itself was considered a positive point of care, especially when it was associated with pain relief. The most negative point was evidenced at times that led to some kind of discomfort in the child such as anesthesia, taste of the prophylactic paste and noise of high rotation. The perception of the operator’s image was considered humanized in all responses. Most children showed satisfaction with their smile and some reported the need to return to the dental clinic for new procedures. Only a small portion was free of oral problems. It is concluded that: the need for dental follow-up is not consistent with the oral health condition of the children evaluated and that the care process follows the curative model.

Keywords:Pediatric Dentistry;child psychology;health evaluation

Introduction

Pediatric dentistry is the dental specialty that takes care of children’s oral health. It is known that the great fear presented by adult patients in the dentist’s chair originates from the negative experiences of dental treatments that occurred in childhood. For this reason, the role of pediatric dentists is of great relevance in dentistry. Pediatric dentists are responsible for the care of children from infants to adolescence, and their exercise is comprehensive, as it is not limited only to the prevention and solution of oral problems, it also plays an important role with regard to the psychological and educational aspects of the patient [1].The practice of children’s dental clinic shows that children have some peculiarities, such as growth and development, biodynamics, tissue and organic responses, behavior, and personality structure. These peculiarities cause the sociological methods and the techniques of physical examination to have a different approach from that performed in adults, despite having the same diagnostic and therapeutic purpose [2]. According to Melo et al. [3], the dentist’s approach must be in accordance with the child’s age and psychological development, and can be used from a more playful language in early childhood to logical explanations in early adolescence, so that in many situations children are driven to overcome fears and phobias. During clinical practice, it can be observed that lessinvasive procedures do not generate major behavioral reactions, whereas more invasive procedures are directly related to rejection and fear in the face of treatment [3].The negative attitude towards dental treatment is a process that begins in childhood, and the origin and cause must be investigated by the Pediatric Dentist before any behavior control technique is applied [4]. According to Gomes et al. [5], the child may manifest fear and anxiety in several ways, the most frequent symptoms being tachycardia, sweating, palpitations, tremor, flushing and gastrointestinal complications.

Behind a behavior, positive or negative, there are a multitude of characters that exert marked influences on children, such as: age; the socioeconomic class of the parents; temperament; psychological development; the environment in which you live. Through such knowledge, the operator / pediatric dentist will have more baggage for the application of certain measures, and for a better understanding of the types of behavior presented by the children[5]. According to the literature, several control techniques can be used, such as: orders; compliments; reward; suggestions; containment; distraction; restriction; dominance by voice and sayshow- do. The pediatric dentist must, therefore, play an active role in the psychological and educational sectors, allowing the avoidance of possible trauma that almost always determines incompatible relationships with the dentist or with the clinical environment or even with the surgical procedures [6]. The control of fear and anxiety during dental treatment must be performed throughout the service. Thus, it is essential to use basic conducts to control the situation, such as verbalization, associated with pharmacological techniques for muscle relaxation or psychological conditioning, reducing the wear of the professional in relation to the patient. The proper use of these behavioral control techniques is fundamental for the success of the planned treatment and consequent restoration of the child’s oral health. The choice of behavioral approach techniques may vary according to the professional’s criteria, being influenced by factors observed during anamnesis, such as age, child’s behavior, and parental acceptance. In this sense, it is of great relevance to establish which procedures generate more behavioral disorders through specific control protocols and techniques for the care of pediatric patients, because regardless of the procedure, it is clear that they present some type of discomfort such as fear and / or anxiety, proving to be of great importance for professionals to update themselves in offering treatment options and techniques so that this moment becomes more dynamic and comfortable, recognizing, first of all, each child with their particularities.Therefore, knowing the child’s perception about the dental experience is extremely important for understanding the dental practice developed within the different environments that offer this service. Such knowledge allows the dental surgeon to identify possible failures committed and can develop new forms of interaction during care, thus modifying negative behaviors and / or reinforcing positive ones. This will allow the use of more effective methods so that they accept and understand the need for the procedure[7].Based on this principle, this study evaluated the perception of children between 3 and 11 years of age regarding dental treatment, the figure of the dentist and their own oral health condition, through analysis of information obtained by interview, drawing on the topic and analysis of medical records.

Method

The present study is characterized in a cross-sectional analytical and descriptive design, where the bibliographic research took place through the consultation of online publications such as: LILACS, SCIELO, BVS, PubMed. The search strategy occurred through Health Sciences Descriptors (DECs) registered in Portuguese as: Pediatric Dentistry, Child Psychology and Health Assessment, which are terminologies that make up electronic articles and made possible their search, in addition to the terms in English: Pediatric Dentistry, Psychology Child and Health Evaluation. 100 publications were found on the proposed theme, including subjects related to fear, anxiety and behavior management, with 33 articles selected, 3 master’s dissertations, 3 conclusion papers of a specialization course and 2 doctoral theses. For inclusion criteria, articles in Portuguese or English were selected, complete and published from 2009 to 2019, in addition to national books that addressed methods of controlling behavior in pediatric dentistry, considering the reliability of the selected material. As exclusion criteria, articles, monographs, and dissertations that do not fit the research objectives, in addition to those that are not available in full.The research was carried out at the Pediatric Dentistry’s School Clinic of the Lutheran University Center of Palmas, during the second semester of 2019.The object of the study was children assisted by the children’s clinic (I and II) of the institution, and the data were collected in the second semester of 2019. A random sample of 21 children aged 3 to 11 years participated in the research. The variables used in this study relate to those observed by the child, in relation to the procedures and the dental environment, and were adapted using a questionnaire already validated, and a drawingstory about their care.

As inclusion criteria, children in need of care participated in the research, whether for the first time or not at the school clinic. Children with motor difficulties or mental disabilities were excluded. Children who refused to do the drawing and answer the questions even with the parent’s permission, were also excluded. Children who failed to answer just one question were not excluded from the sample. Children who stopped making the drawing, but answered the questions, were not excluded from the sample. Based on previous studies and according to several authors [8- 13]the application of the instrument was carried out through a questionnaire already validated, where the child’s perceptions regarding the situation of care were recorded. All data were collected in the clinic environment, each child was approached individually. This collection was made after the service, with the application of a questionnaire containing 8 questions of the type:

a) What is a dentist?
b) Are you happy with your teeth? why?
c) Do you think you need to take more care of your teeth?
why?
d) While you were with the dentist, how did he treat you?
e) How was your reaction during the consultation?
f) What did you like most about the consultation?
g) What did you like least?
h) Finally, how do you feel now?

After the questionnaire was completed, the child was invited to carry out a drawing-story about his care (each child was provided with crayons and a blank sheet to carry out the drawing.), And afterwards, describe the meaning of the researcher to the researcher. In addition to the interview, the researcher was responsible for collecting data regarding the patient’s clinical history at the school clinic. The answers and the description of the drawing were faithfully transcribed and evaluated. Those responsible were informed of the research, and those who wished toparticipate signed the free and informed consent form. The level of invasion of the procedure to which the children were subjected was also subject to classification where they were divided into groups 1 and 2, being classified as invasive procedures (extraction; endodontics; restorations, which require absolute isolation) and not invasive (prophylaxis; topical application of fluoride and use of sealants that are carried out without absolute isolation) respectively. Only those drawings that met the following requirements were included in the study:

focus on the proposed theme
j) be completed
k) be clear for interpretation
l) in isolation or with the help of the child’s oral description.

Result and Discussion

A fluctuating reading was carried out for the initial knowledge of the material produced. Subsequently, the drawings were systematically observed, and the texts obtained for each of them were read, as well as their responses. Thus, the quantification allows to define the shared thought collectively among the researched group. Twenty-one children aged 3 to 11 years participated in the study, with the frequency of each age as follows: 3 years (1), 4 years (3), 5 years (1), 6 years(1), 7 years (3 ) and 8 years (5), 9 years (4) 10 years (2) and 11 years (1). The male gender had the highest frequency (13).

Analysis of the interview

It was found that the majority of respondents reported to more than one subcategory during the interview. The perception of the operator’s image was considered humanized in all reports and the design of the treatment model was described by most children as a curative, with preventive treatment being little mentioned. In the positive view, objects from the dental environment were highlighted, such as, for example, a dental chair, a Robinson brush, and a dental sucker. In the negative view, the most frequent responses were in relation to the dental procedure itselfwhen the treatment generated pain or discomfort: “I did not like the needle” and “I thought that noise was bad”. In the negative view, discomfort related to other objects was also highlighted, such as a needle and explorer probe.

Design analysis

It was identified that most of the interviewees reported to more than one subcategory during the elaboration of the drawingstory. The dental environment category was most frequently addressed, being the subcategories, operator, and equipment. The other categories demonstrated that, according to the child’s view, the institution’s dental treatment presents itself as a curative and technical model; but humanized, where the interviewees reported having been treated with great empathy. The moment of consultation in the days of the survey was reported by the interviewees as a pleasant moment and the environment was referred to as peaceful. The children’s behavior during the observation made by the researcher was satisfactory (positive). The operator was sometimes mentioned in phrases such as: “nice, nice and polite” as well as “he treated me very well”, “she explained what she was going to do”.The appreciation of the dental treatment received by each one was evaluated by means of a positive view (what he liked best) and a negative view (what he liked least). In the positive view, the dental procedure was the most mentioned, when related to the child’s pain relief, as identified in the excerpts: “I liked it when she passed the ointment, and when she removed the tooth, I didn’tfeel anything”; “I liked to pull the tooth out it because it hurt.” In the negative view, the dental procedure was also the most cited when it caused a sensation of pain or discomfort, as identified in the excerpts: “When she put the needle it hurt” and “I didn’t like that thing to brush my teeth”.

Analysis of the record

In the analysis of the medical record, despite the innumerable invasive procedures, most of the subjects showed positive behaviors, as the drawings and the speeches that showed tranquility, empathy towards the dentist, establishing dialogue were expressive; it was evident in the studied group that there is a relationship of trust and good communication between professionals and patients.The self-perception of the oral condition was evaluated as positive by most children, and the most frequent reasons were demonstration of health (8), absence of pain (6), self-care (4) as observed in the report “I’m happy because they they are beautiful ”. For those who negatively assessed their oral health condition, the presence of pain related to the carious process was the main related reason (5). Regarding the need for dental care, most children believe that they should attend other dental appointments (12), for one or more reasons, and the condition “To treat decayed tooth” was mentioned (9) times and procedures related to prevention were cited (3) times. Children who do not intend to return or only want to return in case of pain.It was found that the child’s behavior in the dental consultation can be determined by a series of factors, such as maturity, relationship with parents, approach to the dentist, past experiences, office environment, this because their handling, in some circumstances, becomes a great challenge for the professional. The professional’s positive interaction with the child brings out the image of a humanized professional. In both cases, the most apparent reaction in the child during and after the interview was joyful and calm. Behaviors related to anxiety, fear and scared were mentioned a few times (3), (1) and (2).In the present study, children who claimed to be happy with their oral health condition, even though they were compromised, demonstrate the inability to recognize oral health as an integral part of systemic health, which demonstrates a deficiency in health actions aimed at this evaluated population.

To demonstrate the view that the child has on the care that receives the drawing technique, it proves to be efficient because it is a pleasant activity and easy to perform. This can be seen in the course of this research. All children, after explaining the research, readily accepted the invitation and expressed satisfaction in drawing and reporting their drawings.The analysis of the story-drawings about the dental care provided by the Clinic of Pediatric Dentistry of CEULP-ULBRA showed very positive aspects regarding the actions developed by academics and teachers. The view of the infant patient that was part of this study reflects the effectiveness of the work performed by the teams of the Pediatric Dentistry Clinic of CEULP-ULBRA. The description of the drawings, through the children’s speeches, denoted a scenario of tranquility and empathy. It was very evident that there is a relationship of trust, good communication between academics and children. Communication between the dentist and the child, aimed at a friendly and friendly relationship during care, is essential for the success of dental treatment and, therefore, for the establishment of healthy behaviors. This condition was perceived in the storydesigns carried out by the patients as being from a cordial setting, with good communication and goodwill.Therefore, it is suggested that further studies be carried out in order to identify the best way of working with health professionals in order to encourage the practice of prevention as a health promotion strategy in addition to raising the awareness of children and their guardians. about the importance of periodic dental consultations for the benefit of your children’s health.

Conclusions

For most of the subjects participating in the research, the context of the dental consultation is revealed to be a pleasant situation, characterized by an educational-curative practice, and permeated by a humanized view of the dental professional, configuring itself in a pleasant situation. It was found that even in the midst of invasive procedures, in the days of the research, the children had behaviors of collaboration and demonstration of interest in the care and tranquility during the consultation. It was found that the evaluation process, through the technique of drawing-story, is rich and authentic. Therefore, the technique can be considered an excellent methodological alternative when compared to the use of questionnaires, which can induce the respondents’ answers, limiting the quality and depth of the evaluation process. According to the interview and the medical record findings, the interviewees’ oral health is not consistent, requiring dental follow-up for both new procedures and for hygiene and oral health care instructions.

Lupine Publishers | Early Third Molar Extraction: When Germectomy Is the Best Choise

 Lupine Publishers | Journal of Pediatric Dentistry


Introduction

Third molars are often removed in order to prevent complications and various other problems associated with impacted third molars and their removal. Abortion of mandibular third molars is a procedure carried out at an early age in those subjects where there is insufficient room for the eruption of the third molars. On the other hand, one can also decide to remove the second molars and to annex ate orthodontically the third molars in the arch.

Decision Making

The best time to perform a Germectomy is during one of the three stages of tooth development. The orthodontist will create a treatment strategy that will determine when the surgical phase should commence. While the need may no doubt exist, a global agreement exists on the fact that lower molars should be considered only one between several factors able to cause malocclusion. Thus, the germectomy of the third molars has to be performed only in carefully selected patients after a comprehensive diagnostic evaluation of the single case[1-4].It is also important to note that dental age and bone age to not always correspond with chronological age. In some children calcification of the tooth bud occurs early, while in other children it may be delayed[5-8].

Stage 1: 7-11 years old – Start of tooth bud calcification.

Stage 2: 12-15 years old –Crown mineralization is complete.

Stage3: 14-18 years old –Root formation partially complete.

This period is the most favorable for germectomy because the crypt’s bony cover is partially resorbed, and the crown is still in a submucosal position. While the tooth is retained inside its follicular membrane, there is no risk of infection. When extraction is called for, it is also preferable to operate before the crown has erupted. Doing so avoids peri coronal bacteria.

Surgical Protocol

Figure 1: X ray pre op.

A full-thickness triangular flap is reflected ted with a horizontal incision at the base of the papillae between the sixth and seventh and a distal discharge incision with a vestibular pattern(Figures 1-4).Then we proceed with the osteotomy that can be performed with rotating instruments mounted on a straight handpiece or with a piezoelectric terminal with the dedicated(Figures 5 & 6). Tooth bud sectioning helps reduce the extent of bone removal required and is conduct- ed when the opening is too narrow for total eruption. The crown is secured with the sharp end of a fine elevator at a stage when the roots are not yet formed. The section is carried out from the outside to the inside using aspindle-shaped bur, starting from the previously exposed buccal portion.This section is always incomplete because it must not\reach the lingual wall of the bone crypt. The tooth is then fractured by using a straight elevator along the incision and the fragments are removed using suction cannula or curved hemostatic forceps.The alveolar cavity is cleaned with saline irrigation and filled with collagen sponge and the (4/0) sutures is performed(Figures 7-13).

Conclusions

Germectomy, or early third molar ex- traction, is generally indicated when inf lammation, edema, and pain are exhibited in the young adult patient. The clinician notes by both physical observation and panoramic X-ray that the space restriction will inhibit complete tooth emergence with normal dental and periodontal characteristics [2]. At this early stage of eruption, extraction is some- times associated with complications, chiefly from infection. Also, the surgical procedure may prove challenging. This is due to the nature of the complete root formation and root morphology relative to the mandibular canal. The periodontal environment may also be compromised by the resorption of the alveolar wall of its distal root. Thus, extracting before these challenges arise is the preferred option [9-10].
