Conservative Restorative Management of External Cervical Tooth Resorption: A Case Report

Background: External cervical resorption (ECR) is one of the subclassifications external root resorption. The etiology ECR still unclear. In most cases, it not evident and asymptomatic before involvement pulp. Case presentation: This paper reports a case in mandibular right first molar 24-year-old patient who presented with an pink tooth. A two-dimensional radiograph Cone beam computed tomography (CBCT) showed penetrating at cementoenamel junction level from mesio-lingual aspect. It approximates pulp horn coronally within lingual dentinal wall. Discussion: treatment involved debridement resorptive defect Mineral Trioxide Aggregate (MTA) was applied as direct capping, glass ionomer base, tooth restored using composite resin restoration. After 6-months follow-up, radiographic examination healthy bone periodontal structures no evidence periapical pathology. Conclusion: aggressive invasive lesion that acts silently, requiring early diagnosis for successful outcome. size, location, accessibility are main factors affecting ECR.
