Endodontic-periodontal management of two rooted maxillary lateral incisor associated with complex radicular lingual groove by using spiral computed tomography as a diagnostic aid: a case report.

Abstract：

AIM:To present the successful endodontic and periodontal management of a two rooted maxillary lateral incisor tooth with a complex radicular lingual groove and severe periodontal destruction using spiral computed tomography as a diagnostic aid. SUMMARY:A 30-year-old male patient presented with a chief complaint of mobility and discharge of pus in an upper front tooth. Clinical examination revealed a sinus tract on the labial gingival surface and a 10-mm-deep periodontal pocket associated with maxillary left lateral incisor tooth. On the lingual side, a groove emerging from cingulum, continuing mesioapically down the lingual aspect of tooth was found. Intraoral periapical radiographs demonstrated a lateral periodontal defect around the mesial aspect and a diffuse radiolucency at the apex of maxillary left lateral incisor tooth. The sinus tract was traced with gutta-percha to the maxillary left lateral incisor that showed an accessory root surrounded by a large radiolucent area. A spiral computed tomographic scan for better understanding of the complicated root canal morphology of the tooth was performed. Based on the clinical, radiographic and spiral computed tomographic findings, a diagnosis of an endo-perio lesion in tooth 22 was made. Management consisted of conventional root canal treatment, radiculoplasty, root resection of accessory root and surgical curettage of the periodontal defect. Follow-up with radiographic examination at 3 months and 1 year was performed. At 1-year recall, the patient was asymptomatic, there was no evidence of the sinus tract and a 3-mm nonbleeding pocket was present in relation to tooth 22. Progression of hard tissue healing was observed in the periapical radiograph taken 1 year postoperatively. KEY LEARNING POINTS:The key to achieving favourable results in this particular type of developmental anomaly is accurate diagnosis and treatment planning. The health of the periapical osseous tissues appears to be the provital factor for tooth retention. A favourable outcome can only be achieved with a comprehensive treatment approach that effectively manages all local factors that are contributing to the disease process.
