Non-surgical root canal treatment of dens invaginatus type 2 in a maxillary lateral incisor
Discussion - References.

Clinicians should be aware of the incidence and methods for treating dens invaginatus . Failure to locate, debride and obturate complex root canal spaces will lead to failure in some cases. According to the classification of Oehlers (1957) the present case was a type 2. In this type of dens invaginatus , the invagination remains confined within the root as a blind sac, which may communicate with the pulp. However, in this case the invagination did not appear to communicate with the pulp and clinical exploration during root canal treatment corroborated this assumption. Therefore, the aetiology of the periapical pathosis in this case was due to the infected primary root canal. However, it is not known how long the primary root canal had been infected prior to the patient developing symptoms. Mechanical debridement of the primary root canal was difficult, but the combination of chemomechanical instrumentation and the use of calcium hydroxide were sufficient without resorting to surgery. As calcium hydroxide has been reported to successfully eliminate bacteria (Byström et al . 1985) and stimulate hard tissue repair (Heithersay 1975), it was decided to treat the primary root canal with this medicament before obturating the root canal with gutta-percha. The use of a warm gutta-percha technique helped to obturate the root canal system, as it was possible to compact the softened material into the major irregularities within the root canal system (Budd et al . 1991, Gutmann 1993).
