Role of Microendodontics in Detection of Root Canal Orifices: A Comparative Study between Naked Eye, Loupes and Surgical Operating Microscope
Journal Title: Journal of Medical Science And clinical Research - Year 2015, Vol 3, Issue 10
Abstract
Aim: The aim of this study was to compare the detection rate of root canal orifices by three different methods: naked eye, with surgical loupes and under a surgical operating microscope. Material and methods: Sixty extracted permanent maxillary molars and sixty extracted permanent mandibular molars were collected. Access cavity was prepared. After an access cavity, the long shank spoon excavator was used to remove the contents of the chamber and irrigation was done with 5% sodium hypochlorite. The existence of each orifice was recorded when a K-file #8 or #10 pushed into the orifice was able to stand by itself. The teeth were divided into four groups (1-4). In each group the number of root canal orifices were recorded using naked eye (Gp 1), loupes (Gp 2), surgical operating microscope (Gp 3) and after tooth clearing technique (Gp 4). Tooth clearing technique gave the actual number of root canal orifices and was used as a standard for comparison. Statistical analysis: Chi square test was used. Result: There was significant difference between groups 1 and 3; and groups 2 and 3. Although the number of orifices detected was greater with loupes (Gp 2) than eye (Gp 1) but it was not significant. Conclusion: The number of orifices detected increased with increasing magnification. Experience of the operator influences the detection rate of root canal orifices. The microscope could more accurately detect orifices statistically than the other two methods.
