“…In the present case, the teeth involved were vital and radiographically no distinct hyperostotic border was noticed. Though the radiographic features of LPC in the present case were in accordance with that of the routine findings,6 clinically the cyst measured about 3×2 cm that categorises the present case into one of the unusual types of LPC, in addition to it being present in the mandible.…”

Lateral periodontal cyst, developmental in origin, typically is observed in the cuspid–bicuspid region of the mandible and less frequently in the maxilla. It may arise initially as a dentigerous cyst developing by expansion of the follicle along the lateral surface of the crown which eventually comes to lie on the lateral aspect of the root if tooth eruption is normal. Alternatively, it may arise from the cell rests of malassez. The incidence of lateral periodontal cysts has been reported to be less than 1% and these cysts represent nearly 0.8% of all central cysts of the maxillary bone. Here we present one such case with unusual findings.

“…Interpretation of the radiograph is subjective (27), whereas biopsy is the definitive diagnostic tool, especially in light of recent case reports (28)(29)(30)(31). Most of the nonhealing radiolucent lesions submitted for biopsy were either apical granulomas (40.4%) or apical cysts (33.1%), and they were often from the maxillary anterior jaw.…”

“…Literature review shows that the LPC is more prevalent in adults in the 5th - 7th decades, with mean age of 52 years, without preference for race or sex. The most frequently reported location of LPC is the mandibular premolar area, followed by the anterior region of maxilla (Table 1) [5,6,8,11-20]. In most cases the LPC does not present distinctive clinical symptoms; the associated teeth are vital, unless secondarily infected.…”

BackgroundThe lateral periodontal cyst is considered a developmental odontogenic cyst with unusual occurrence. In most cases it is preliminary diagnosed as a radiographic finding, presenting as well circumscribed or as a round or teardrop-shaped radiolucent area. Due to its location it can easily be misdiagnosed as a lesion of endodontic origin. Final diagnosis should be based on histopatological examination. The purpose of this paper is to report a classic case of lateral periodontal cyst located in the anterior region of mandible and to review the relevant literature which describes the clinical, radiological and histopathological features of lateral periodontal cysts.MethodsA 50 years female patient complained of an asymptomatic gingival swelling in the region between the left mandibular lateral incisor and canine. Radiographic examination revealed a well circumscribed radiolucency with approximately 0.5 cm diameter with a radiopaque margin between the roots of the left mandibular lateral incisor and canine. The adjacent teeth had vital pulp.ResultsA total enucleation of the lesion was performed, and intraoperative examination showed a single lesion with no communication between the cyst's cavity and the oral environment. Histological examination revealed that the lesion was "lateral periodontal cyst of developmental origin". There was no recurrence or complications for 24 months follow-up.ConclusionsThe lateral periodontal cyst can be considered in the differential diagnosis when a radioloucent lesion appears adjacent to the roots of vital teeth. The treatment of choice is surgical removal and subsequent histological evaluation to confirm the diagnosis. Relapses are infrequent.
