Abstract This study was conducted to evaluate the effect of dental loupe and headlamp in detecting the MB2 canal in extracted maxillary first molars. 100 extracted mature maxillary first molars were randomly selected for this study. After cleaning of the teeth and taking preoperative radiograph, they were mounted in resin blocks and rhomboidal-shaped access cavities were prepared. The floor of the pulp chamber was explored to locate the main root canal orifices. Each tooth was subjected to five detection methods to detect the MB2 canals. Group I, II, III, IV and V were the result of using unaided vision, headlamp and 3.5 magnifying dental loupe, unaided vision following the use of start X # 2 ultrasonic tip, headlamp and 3.5 magnifying dental loupe following the use of start X #2 ultrasonic tip, and clearing technique detection methods respectively. The transparent teeth were viewed through stereomicroscope and mesiobuccal root canal systems were categorized according to Weine and Verrtucci classification The number of canals that were detected by each method was recorded and the results were statistically analyzed using Z-test. The results of this study proved that using headlamp and 3.5 magnifying dental loupe with or without Start X #2 ultrasonic tip significantly facilitate detection of MB2 in maxillary firs molars. |
