Intraoral photographs showing severe incisal attrition of all the mandibular incisors. Vertucci in 1974 classified the canal configuration of mandibular incisors into four types: 3 2 However variations in form of presence of extra canal in mandibular incisors have been documented by various researchers in the past. Many studies have examined the root canal systems of these single-rooted teeth, confirming that it is not as simple as it may appear to be on standard periapical radiographs. The morphology of mandibular central and lateral incisors is very similar.
Inadequate knowledge regarding variations of root canal system may be a major cause of the failure of root canal system.Įndodontic treatment of single rooted teeth is usually simple as these teeth usually have single root canal. 1 Variations in form of aberrant canal configurations, accessory canals, bifurcation, isthmuses, and anastomoses are often difficult to identify, thus creating a problem for endodontic treatment. Ingle lists the most frequent cause of endodontic failure as apical percolation and subsequent diffusion stasis into the canal. To achieve these goals, locating, cleaning and shaping the entire canal system is a must. The main objective of endodontic therapy is to prevent and when needed to cure endodontic disease and apical periodontitis.
For successful endodontic treatment, thorough knowledge of root canal morphology along with its variation is mandatory.
