Palatoradicular groove: The hidden predator and etiological factor - Advanced proposed classification and literature review.

Palatoradicular grooves are usually found on the palatal or lateral roots of maxillary central and lateral incisors. Since clinical identification of these grooves are inaccessible and arduous in routine oral hygiene practices and are susceptible alcoves for microorganism habituation and plaque accumulation, it may result in acute to severe periodontitis and, if untreated, periapical pathosis also. This paper discusses about a female patient who reported pus discharge in left upper lateral incisor. Based on history, clinical examination and IOPA (intra-oral periapical radiograph), a deep pocket of about 10–14 mm was noticed in the left upper lateral incisor. A timely investigation was made and was treated surgically with advanced modified procedures which include odontoplasty and restoration of the defect with Platelet Rich Fibrin. After follow up of 6 months, the patient reported no signs of disease progression, had good oral hygiene and the tooth remained to be vital.
