RESUMO
Several morphological abnormalities may occur during tooth development and may be a predisposing factor for periodontal destruction. Palatogingival groove (PGG) is a developmental deformity that may cause localized periodontitis and endodontic complexities. The groove usually originates as a root indentation in the central fossa of the palatal root of maxillary lateral incisors. Cone beam computed tomography (CBCT) is an excellent radiographic imaging technique capable of identifying PGGs and provides details about the exact site, extent, and depth characteristics of this deformity. Early diagnosis and management of PGGs are of utmost importance, particularly due to their diagnostic intricacies that can pose both clinical and therapeutic challenges. This article aims to report a rare case of palatogingival groove associated with an on-and-off discharge from the maxillary left lateral incisor tooth (#22). Nonsurgical endodontic treatment was carried out with #22, and the palatogingival groove was sealed with composite restoration after a deep curettage. Excellent radiographic healing was observed after a six-month follow-up.
RESUMO
O objetivo dessa revisão de literatura é verificar as estratégias de tratamento das lesões endo-periodontais. Foi realizada uma busca na literatura, nas seguintes bases de dados: Medline, Crochane, PubMed e Scielo, contendo artigos científicos dos últimos dez anos nos idiomas inglês e português usando os termos de pesquisa: "Tratamento" E/OU "Lesões Endo-periodontal" E/OU "doença periodontal" E/OU "Endodontia". As lesões endo-peridontais são caracterizadas pela interação doença periodontal e endodôntica e são patologias de difícil diagnóstico clínico. Seu tratamento consiste na terapia endodôntica, terapia periodontal ou ambas. Os tratamentos empregados para as lesões são: Lesões endodônticas primárias: apenas tratamento endodôntico. Lesão endodôntica primária com envolvimento periodontal secundário: primeiramente tratamento endodôntico e após periodontal. Lesão periodontal primária: apenas tratamento periodontal. Lesão periodontal primária com envolvimento endodôntico secundário: primeiramente endodôntico, na sequência periodontal. Lesões verdadeiras combinadas: necessidade de tratamento endodôntico inicial e em seguida periodontal. Uma vez que o tratamento endodôntico tenha sido eficiente, o prognóstico do tratamento dessas lesões depende da severidade da doença periodontal e da resposta dos tecidos periodontais ao tratamento (AU)
The objective of this literature review is to verify the strategies of treatment of the endo-periodontal lesions. A literature search was conducted in the following databases: Medline, Crochane, PubMed and Scielo, containing scientific articles of the last ten years in the English and Portuguese languages using the search terms: "Treatment" AND/OR "Periodontal-endodontic lesions" AND/OR "Periodontal diseases" AND/ OR "endodontic". Endo-periodontal lesions are characterized by the interaction of periodontal and/ or endodontic disease. These are pathologies difficult to diagnose clinically. Their treatment consists of endodontic therapy, periodontal therapy or both. The treatments used for the lesions are: Primary endodontic lesions: only endodontic treatment. Primary endodontic lesion with secondary periodontal involvement: Firstly endodontic treatment and after periodontal treatment. Periodontal lesion primary: only periodontal treatment. Primary periodontal lesion with secondary endodontic involvement: Firstly endodontic, in the periodontal sequence. True true lesions combined: Need for initial and then periodontal endodontic treatment. Since endodontic treatment has been effective, the prognosis of treatment of these complex lesions depends on the severity of periodontal disease and the response of periodontal tissues to treatment (AU)
