ABSTRACT
Palatogingival groove (PGG) is an anomaly in the maxillary anterior teeth, often accompanied by the area of bony destruction adjacent to the teeth with no carious or traumatic history. The hidden trap in the tooth can harbor plaque and bacteria, resulting in periodontal destruction with or without pulpal pathologic change. Related diseases can involve periodontal destruction, combined endodontic-periodontal lesions, or separate endodontic and periodontal lesions. Disease severity and prognosis related to PGG depend on several factors, including location, range, depth, and type of the groove. Several materials have been used and recommended for cases of extensive periodontal destruction from PGG to remove and block the inflammatory source and recover the health of surrounding periodontal tissues. Even in cases of severe periodontal destruction, several studies have reported favorable treatment outcomes with proper management. With new options in diagnosis and treatment, clinicians need a detailed understanding of the characteristics, treatment, and prognosis of PGG to successfully manage the condition.

O sulco palato-gengival (SPG) é uma anomalia de desenvolvimento que acomete principalmente os incisivos superiores. Inicia-se no ou perto do cíngulo dental, e sulca a raiz apresentando uma grande variedade de profundidades e comprimentos. Sua incidência, profundidade e comprimento, são de importância clínica, uma vez que em periodontia podem ser o agente causal de periodontites severa se localizadas, e na endodontia provocam a divisão do canal radicular e o aparecimento de foram es acessórios. O objetivo deste trabalho foi realizar um estudo sobre a presença, forma, comprimento e profundidade do sulco palato-gengival em incisivos centrais superiores. Foram utilizados 1.668 dentes incisivos centrais superiores da coleção de dentes da Disciplina de Anatomia do ICT - SJ Campos UNESP. Cada dente teve a sua porção radicular inspecionada com a finalidade de verificar a presença e a profundidade do SPG. Os sulcos palato-gengivais encontrados foram classificados de acordo com o sistema proposto por Gu (2011), em: Tipo I (curtoe superficial), Tipo II (longo e superficial) e Tipo II (longo e profundo). Concluída esta classificação,todos os dentes que apresentaram o SPG foram radiografados e cinco dentes tiveram sua superfície radicular avaliada através do uso de um Microscópio Eletrônico de Varredura (MEV). Finalmente foram separados quatro dentes representativos de cada tipo de SPG encontrado para a obtenção de cortes histológicos e subsequente análise microscópica.
Palatogingival groove (PGG) is a developmental anomaly affecting mainly the maxillary incisors.PGG incidence, depth, and length are clinically important because it may cause severe and localized periodontitis; and it may divide the root canal resulting in accessory foramina. This study aimed to analyze the presence, shape, length, and depth of the palatogingival groove in maxillary central incisors. 1,668 maxillary central incisors were used. Each tooth had its root portion inspected inorder to verify PGG presence and depth. The found palatogingival grooves were classified according tothe system proposed by Gu [5], as follows: Type I (short and superficial), Type II (long and superficial),and Type III (long and deep). All teeth that showed the grooves were radiographed; five teeth had their root surface analyzed through Scanning Electron Microscopic (SEM); and four teeth corresponding to each PGG type were sent to obtain histological sections and then submitted to microscopic analysis.Of the 1.668 analyzed incisors, 27 (1.61%) showed the palatogingival groove: 8 (29.6%) Type I, 17(63%) type II, and 2 (7.4%) Type III. Microscopic analysis revealed no communication between PGGand root canal. In conclusion, our results showed that PGG can be clinically and radiographically diagnosed on maxillary central incisors, with the type II being the most common. The professionals should be aware of the features of this groove dueto its severe clinical consequences.

Morphological defects occurring in dental structure can be sometimes predisposing factors for the onset of inflammatory processes in the periodontal and/or pulpal tissues. Palatogingival groove is one such defect, most frequently found on the lingual surface of maxillary laterals. They are easily overlooked as aetiologic factors, as these grooves are covered by periodontal tissues. This case report discusses successful management of a root-canal treated maxillary lateral incisor with an associated radicular lingual groove having persisting inflammatory condition. The management included a combination of endodontic therapy and periodontal regenerative techniques.
ABSTRACT
Morphological defects occurring in dental structure can be sometimes predisposing factors for the onset of inflammatory processes in the periodontal and/or pulpal tissues. Palatogingival groove is one such defect, most frequently found on the lingual surface of maxillary laterals. Recognition of such a defect is critical and important, especially because of its diagnostic complexity and its further consequences. This case report discusses about the diagnosis and management of such a defect that predisposed the maxillary lateral incisor to periodontal defect leading to retrograde pulpitis.
ABSTRACT
Palatogingival groove is a rare developmental anomaly involving the lingual surface of the maxillary incisor and resulting in severe endodontic and periodontal lesions. This case report describes a multidisciplinary approach for the combined management of the endodontic and periodontal problems for successful rehabilitation of the involved tooth. Cone-beam computed tomography (CBCT) helped in correct diagnosis of the lesion and hence enabled effective treatment.

OBJECTIVES: Palatogingival groove is a developmental anomaly that starts near the cingulum of the tooth and runs down the cementoenamel junction in apical direction, terminating at various depths along the roots. While frequently associated with periodontal pockets and bone loss, pulpal necrosis of these teeth may precipitate a combined endodontic-periodontal lesion. This case presents a case of a lateral incisor anatomically complicated with palatogingival groove. METHODS: Two patients with lesion associated with the palatogingival groove were chosen for this report. Palatogingival grooves were treated with different restoration materials with endodontic treatment. CONCLUSIONS: Maxillary lateral incisor with a palatogingival groove may occur the periodontal disease with pulpal involvement. Elimination of groove may facilitate the periodontal re-attachment and prevent the recurrence.
