Palatogingival groove also known as radicularlingual groove is a developmental anomaly involving the lingual surface of the maxillary incisors. They are inconspicuous, funnel-shaped, extend for varying distances on root surface and occur due to infolding of the hertwigs epithelial root sheath. This encourages adherence of microorganisms and plaque to levels significant for pathological changes resulting in endodontic and periodontal lesions. The variations in anatomy of the tooth as a cause of pulp necrosis in teeth of anterior maxillary segment should be considered by the clinician when other etiological factors are ruled out. Recognition of palatogingival groove is critical, especially because of its diagnostic complexity and the problems that may arise if it is not properly interpreted and treated. Regeneration is a new emerging approach in endodontics. Choukroun et al. were among the pioneers for using platelet-rich fibrin (PRF) to improve bone healing. PRF is rich in platelet cytokines and growth factors. Numerous techniques have been used to eliminate or seal the groove and regenerate endodontic and periodontal tissues. In this case report of two cases, a novel combination therapy involving ultrasonics, blend of PRF with bone graft, guided tissue regeneration membrane was used in the treatment of a palatogingival groove with an endoperio lesion to ensure arrest of disease progression and promote regeneration. The groove was cleaned and prepared ultrasonically and sealed with a bioactive dentin substitute.
