Abstract
Palatal radicular grooves (PRGs) are developmental anomalies of maxillary incisors, when present can act as a site for plaque accumulation and periodontal infection. They are easily overlooked as etiologic factors, as these grooves are covered by periodontal tissues. The clinician has to be alert and check for variations in the anatomy of the tooth as a cause of pulp necrosis in the anterior segment of the tooth when other causes are ruled out. It is often associated with incorrect diagnosis, and subsequent treatment failure. This case report describes the diagnosis and management of two cases of Type II PRG of a maxillary lateral incisor with periapical and periodontal regeneration. Clinical Relevance to Interdisciplinary Dentistry PRG presents with myriad symptoms. Accurate diagnosis requires careful clinical and radiographic examination and advanced imaging, in doubt. Early detection and an interdisciplinary approachs are required to improve the prognosis of the involved tooth. Platelet-rich-fibrin acts as the promising material of choice for regeneration of lost structures and faster soft tissue wound healing.
