Rotary Systems Versus Manual K-File System in Primary Molar Root Canals - In Vitro Study

 

Abstract

Aim: To evaluate and compare the cleaning ability between two, rotary shaper and manual K-files in primary molar root canals.

Material and method: Twenty extracted maxillary and mandibular primary molars and 10 mm length were cleaned in water and stored in 0.5% sodium hypochlorite for 1 week. Caries excavation was done. Coronal access was made. After irrigation of the root canal with normal saline, a K-file with a compatible diameter was introduced into the root canal and the canal length was determined. A K-file size #15 was introduced into the root canal and 1 ml Indian ink was injected into the orifice. The roots were then randomly divided into 2 groups.
