Multidisciplinary conservative management of invasive cervical resorption in an adolescent patient: a 2-year follow-up case report

Abstract

Invasive cervical resorption (ICR) is a complex pathological condition characterized by the progressive loss of dental hard tissues in the cervical region, often remaining asymptomatic during its initial stages. This case report delineates the multidisciplinary conservative management of an ICR affecting a mandibular incisor in a 17-year-old patient. The patient presented with a pink discoloration of tooth 3.2 (mandibular left lateral incisor) without accompanying pain or mobility. Clinical examination revealed physiologic periodontal probing, negative percussion response, and positive pulp vitality tests. The 2D radiographic assessment demonstrated a radiolucent lesion at the cemento-enamel junction with a destructive pattern and no evident pulpal involvement. Clinical findings confirmed that the resorptive defect communicated with both the buccal and lingual surfaces. A diagnosis of Class III invasive cervical resorption, according to Heithersay, was established. An approach aimed at preserving the tooth was adopted, including surgical exposure of the margins, endodontic therapy, adhesive reconstruction, orthodontic extrusion, and final prosthetic rehabilitation.
At the 2-year follow-up, the tooth demonstrated clinical stability and satisfactory functional and esthetic integration. This case underscores the significance of a multidisciplinary approach in managing complex resorptive lesions and emphasizes the importance of prioritizing tooth preservation in young patients.
