Effect of Trauma to Primary Tooth on Permanent Maxillary Incisors: A Clinical Case Report.

Trauma to primary tooth leads to abnormal variations in crown and root canals of permanent teeth that presents a challenge in diagnosis and clinical management to the practitioner. This article presents a detailed case report of the endodontic treatment of a three canalled maxillary central incisor and maxillary lateral incisor having single canal with open apex linked with periodontal defect. Root canals were prepared with hand files and canals were irrigated with 2.5% sodium hypochlorite solution. Calcium hydroxide was placed as an intracanal medicament. As the expected healing did not occur even after one month of calcium hydroxide therapy, so periapical endodontic surgery was performed using Platelet Rich Plasma (PRP). Satisfactory clinical and radiographic results were obtained at 12 months. Detailed knowledge of the anatomical variations in the root canal and awareness of their configuration is essential for the success of such cases.
