Lateral periodontal cyst - case report and literature review

The lateral periodontal cyst is a rare type of odontogenico cyst of unknown etiology. It usually occurs in the premolars, it is generally asymptomatic and in some cases leads to expansion of cortical bone. When seen in the radiographic appearance, has well-defined unilocular radiolucency. Aim: This study aims to report the case of a 44 years old male who came to us complaining of swelling associated with discomfort in the second inferior right premolar. After a thorough diagnostic evaluation, surgical excision was performed and microscopic examination proved to be a lateral periodontal cyst, as previously hypothesized after clinical examination. This case report also discusses the importance of following an appropriate protocol to establish differential diagnosis and accordingly treatment.
