Aim: The study was designed to compare the efficiency of three different methods used for retreatment using a dental operating microscope (DOM) and a stereomicroscope and to evaluate and compare the two methods for detection of residual obturation material after retreatment.
Background: The DOM can play an important role in the successful retreatment by detecting the remaining obturation material.
Materials and Methods: Thirty extracted maxillary central incisors were collected and obturated after biomechanical preparation. The samples were divided into three groups depending on the method of retreatment: Group I, H-files; Group II, ProTaper Universal retreatment files; and Group III: H-files + Gates-Glidden drills, with 10 samples in each group. After retreatment, the samples were observed under a DOM for detection of residual obturation material. Later, the teeth were cleared and observed under a stereomicroscope for detecting the remaining filling material. The results were subjected to the Spearman«SQ»s rank order test and other statistical analysis.
Results: The maximum cleanliness of the root canal walls was seen in Group I while Group II showed the least. The difference between the mean scores obtained with a DOM and a stereomicroscope was statistically significant (P = 0.05).
Conclusion: None of the techniques could completely remove the obturation material. The root canal cleanliness is best achieved when retreatment is performed under a DOM.
