Management of an Endodontic-Periodontal Lesion in a Maxillary Lateral Incisor with Palatal Radicular Groove: A Case Report

The radicular groove is a developmental anomaly that predisposes the tooth to periodontal break-down. Sometimes the situation becomes more complicated by pulp necrosis and development of a combined endodontic-periodontal lesion which is a diagnostic and treatment challenge for the clinician. This report presents the successful management of an endodontic-periodontal lesion in a maxillary lateral incisor that has a developmental palatal radicular groove using a combination of nonsurgical endodontic therapy and periodontal regenerative techniques. Conclusion: The combination of nonsurgical endodontic and periodontal regenerative treatment is a predictable method in treating combined endodontic-periodontal lesions caused by palato-gingival groove.Keywords: Endodontic-Periodontal Lesion; Maxillary Lateral Incisor; Palatoradicular Groove; Periodontal Regeneratio

Materials and Methods: This was a descriptive and cross-sectional study on 267 parents of preschool children reffering to the dental clinic of SUMS. Data was gathered by means of a questionnaire and interview. The questionnaire was composed of 22 parts including 21 multiple-choice questions and one open-ended question.
