Abstract
To evaluate and compare the cleaning ability between two, rotary shaper and manual K-files in primary molar root canals. 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.
Highlights
The premature loss of primary teeth may cause changes in the chronology and sequence of eruption of permanent teeth
Results showed that Group-A (K-File) performed better at the apical thirds, reporting complete removal in 83.3% of cases followed by coronal third and the least percentage of complete removal was displayed in the middle third with only 43.3% of cases reporting complete removal
Results showed that Group-B performed better at the Coronal and middle thirds, reporting complete removal in 76.7% of cases and the least percentage of complete removal was displayed in the apical third with only 23.3% of cases reporting complete removal
Summary
The premature loss of primary teeth may cause changes in the chronology and sequence of eruption of permanent teeth. The main aim of cleaning and shaping the root canal system is removing soft and hard tissue, which contains bacteria, making space for irritants to the apical third and medicaments, and subsequent obturating material in the radicular structure. The outcome of endodontic treatment in primary teeth is dependent on microbial reduction because of chemo mechanical preparation, removal of residual pulp tissue and debris, and maintenance of the original canal curvature during instrumentation. Stainless steel hand instruments being used for cleaning and shaping of root canals are not efficient enough in preparation of narrow and curved canals due to their inherent stiffness.
