AIM: To analyse the root canal morphology of mandibular third molars using clearing technique. MATERIAL AND METHODS: Ninety permanent extracted mandibular third molar teeth were collected based on inclusion and exclusion criteria. Teeth were then decalcified and were made transparent Methylene Blue Dye was injected to color the pulp space. These teeth were then observed under sterio Microscope and root canal systems were identified according to Vertucci's Classification. RESULTS: The most common anatomical morphology found was having two roots. Overall type I Vertucci’s configuration was the most common pattern of canals. Other canal patterns that were found included type II, III, IV and V. In this study no canal of type VI, VII or VIII were found. CONCLUSION: The morphological variations in root patterns and canal configuration of mandibular third molar should be given consideration for successful endodontic treatment.
