Lateral periodontal cyst (LPC) is an uncommon type of developmental  odontogenic cyst 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 LPC based on the clinical, radiographic examination, and histopathologicanalysis, and to display the treatment of the case. The clinical, radiographic, and histopathological examinations were carried out in the case confirming the diagnosis of LPC. Surgical enucleation was performed on the lesion. In the follow-up of the case there was complete bone regeneration and no recurrences. Although the occurrence of lateral periodontal cyst is rare, the precision of its diagnosis is necessary so that the correct treatment can be established. https://biomedpharmajournal.org/vol10no1/lateral-periodontal-cyst_a-case-report/ Lateral periodontal cyst Odontogenic Cyst
