Lateral periodontal cyst (LPK) is a type of developmental odontogenic cyst that is localized on the lateral surfaces of the teeth, mostly in the mandibular and premol area, and is rarely seen. The pathology is unknown, but it is believed to be derived from mine epithelial, material cell remains or dental lamina remains. It is often asymptomatic and can be detected by a routine radiological examination.  The radiographic image is usually in the form of well-limited, round or oval radiolusent injury. The distinctive diagnosis of the lateral periodontal cyst should be done with the radical cyst, the glandular odontogenic cyst and the odonto-genic keratocistic tumor that can be seen in the same area. In the presentation of this phenomenon, the treatment of the lateral periodontal cyst localized in the mandibular premolar area, identified in a 40-year-old male individual, is offered.

LPC lesion is now believed to originate from emal epithelium, remains of Malassez and dental lamina remains. It is often asymptomatic and can be observed during routine radiological examinations.  Radiographic image is usually in well-defined, round or oval-shaped radiolucent lesion form. The differential diagnosis of the lateral periodontal cyst should be taken into consideration from the radicular cyst, the glandular odontogenic cysts and odontogenic keratocyst tumors be able to be seen in the same region. In the present study, treatment of lateral periodontal cyst localized around the mandibular premolar region be able to be observed on 40-year-old man is presented.
