External cervical root resorption (ECRR) is the loss of dental hard tissue as a result of odontoclastic action.It usually begins on the cervical region of the root surface of teeth.Lesions are frequently misdiagnosed and confused with caries and internal resorption.As a result, inappropriate treatment is often initiated.Early diagnosis and appropriate treatment are the keys to a successful outcome.The etiology of ECRR is mainly trauma, orthodontic treatment or idiopathic factors.The aim of this study is to describe a combined surgical-periodontal-endodontic-restorative treatment of an external cervical resorption Heithersay Class III case with ECRR of idiopathic nature on tooth #43.Treatment was combined: surgical-periodontal treatment exposed the resorptive defect, followed by surgical removal of inflammatory tissue, restorative treatment using resin-modified glass ionomer cement and endodontic therapy because of the necrotic pulp.After 12 months of clinical and radiographic control, recurrence of resorptive lesion was non-existent.
