ABSTRACT
Lateral periodontal cyst (LPC) is an uncommon type of odontogenic cyst of developmental origin that typically occurs laterally on the root surface of a tooth. They are frequently located in the mandibular premolar area followed by the anterior region of the maxilla. It is usually asymptomatic and is discovered on a routine radiograph. The involved teeth are usually vital. Although the occurrence of lateral periodontal cyst is rare, the precision of its diagnosis is necessary so that the correct treatment can be established. The features of a LPC can be easily confused with a odontogenic keratocyst and radicular cyst

Purpose: Lateral periodontal cyst (LPC) is an uncommon type of odontogenic cyst of development that typically occurs laterally on the root surface of a tooth, representing 0.8% of cysts in the jaws. The objective of this article was to describe the diagnosis of three cases of LPC based on the combined results of pulp vitality test, radiographic examination, and histopathologic analysis, and to display the treatment of these cases. Case description: The physical, radiographic, and histopathological examinations were carried out in all the three clinical cases presented, confirming the diagnosis of LPC. Surgical enucleation was performed on the three lesions. In the follow-up of the two last cases, there was complete bone regeneration and no recurrences. Conclusion: Although the occurrence of lateral periodontal cyst is rare, the precision of its diagnosis is necessary so that the correct treatment can be established.
Objetivo: O cisto periodontal lateral (CPL) é um tipo incomum de cisto odontogênico de desenvolvimento que tipicamente ocorre lateralmente à superfície radicular de um dente, representando 0,8% dos cistos nos maxilares. O objetivo deste trabalho foi diagnosticar o CPL associando os resultados de exame de vitalidade pulpar, exame radiográfico e análise histopatológica. Descrição dos casos: Estes exames clínicos e histopatológicos foram realizados nos três casos clínicos apresentados, confirmando o diagnóstico de CPL. Nas três lesões foi realizada a enucleação cirúrgica. No acompanhamento dos dois últimos casos observou-se regeneração óssea completa e sem recorrências. Conclusão: Apesar da ocorrência rara do cisto periodontal lateral, a precisão do diagnóstico se faz necessária para que seja estabelecido o tratamento correto.

O objetivo deste estudo foi descrever um caso clínico de Cisto Periodontal Lateral encontrado em uma paciente de 47 anos, que foi confirmado por exames radiográfico e histopatológico. O Cisto Periodontal Lateral é um tipo raro de cisto odontogênico de desenvolvimento, não ceratinizado, que ocorre adjacente ou lateral a uma raiz dentária de dente vital e corresponde a 1,5% dos cistos dos maxilares. É encontrado principalmente em adultos entre a 5ª e a 7ª décadas de vida, sem distinção quanto ao sexo. Sem sinais dolorosos ou sintomas clínicos, são normalmente diagnosticados durante exames radiográficos de rotina, porém, para um diagnóstico correto é preciso também avaliar as características histopatológicas. O tratamento se faz por enucleação cirúrgica. Apesar de não tender à recorrência, recomenda-se a proservação por alguns anos.
The objective of this study was to describe a clinical case of Lateral Periodontal Cyst found in a 47 year-old patient, which was confirmed by radiographic and histopathologic examinations. The Lateral Periodontal Cyst is a rare type of odontogenic cyst of development, not keratinized, adjacent or lateral to a root of vital tooth and corresponds to 1.5% of cysts in jaws. It is found mainly in adults between 5 th and 7 th decades, without distinction related to sex. With no painful signs or clinical symptoms, these cyst are usually diagnosed during a routine radiographic examination, however, for a correct diagnosis, the histopathologic characteristics must be assessed. The treatment is done by enucleating surgery. Although there is no trend to recurrence, it is recommended to follow-up for some years.
