Five developmental anomalies in a single patient: a rare case report.

Developmental dental anomalies are marked deviations from the normal colour, contour, size, number, and the degree of the development of teeth. Local as well as systemic factors may be responsible for these developmental disturbances. Such influences may begin before or after birth and hence the deciduous or the permanent teeth may be affected. These anomalies not only affect the aesthetic appearance of the teeth but also pose difficulties during the dental treatment and sometimes are the cause of dental problems.A rare case of dental developmental fusion of the permanent right lateral incisor with two supernumerary teeth, with dens invagination, dilacerations, talon's cusp and a periradicular lesion reported to the Department of Oral Medicine and Radiology, NHDC.The clinical and the radiographical findings led to the diagnosis of fusion of the permanent lateral incisor with two supplementary teeth. All the 3 involved teeth showed dens invaginatus, dilacerations of the roots and a talons cusp with a chronic periapical lesion.The rarity with which this entity appears, along with its complex characteristics, often makes it difficult to treat. A multidisciplinary approach, with different specialists working together, can contribute to the success of a treatment plan.
