Abstract

Objective

This report describes an unusual case of a lateral periodontal cyst (LPC) residing between the roots of a mandibular first and second molar.

Background

The LPC is a developmental odontogenic cyst, the majority situated along the lateral roots of the mandibular canines and premolars. The occurrence of an LPC solely confined to the molar region is extremely rare. Limited information regarding the LPC has appeared in the geriatric literature.

Patient Presentation

A unilocular cyst-like lesion was incidentally discovered on extraoral and intraoral radiographic examinations involving a 68-year-old patient. It was initially considered an infected odontogenic keratocyst or unicystic ameloblastoma.

Results

Histologic examination of the excised specimen revealed a thin cuboidal epithelial lining with focal nodular thickenings and underlying fibrovascular connective tissue wall. The lesion was diagnosed as an LPC. At a 6-month follow-up, the patient has remained asymptomatic and exhibited radiographic osseous regeneration.

Conclusions

The LPC should be added to the differential diagnosis of developmental odontogenic cysts found in the inter-molar region. A preoperative cone beam computed tomography scan may be helpful to optimise the surgical approach. Timely removal of any suspected cystic lesion, particularly in the context of infection in an older patient, may reduce postoperative sequelae and rule out malignancy.

期刊介绍: The ultimate aim of Gerodontology is to improve the quality of life and oral health of older people. The boundaries of most conventional dental specialties must be repeatedly crossed to provide optimal dental care for older people. In addition, management of other health problems impacts on dental care and clinicians need knowledge in these numerous overlapping areas. Bringing together these diverse topics within one journal serves clinicians who are seeking to read and to publish papers across a broad spectrum of specialties. This journal provides the juxtaposition of papers from traditional specialties but which share this patient-centred interest, providing a synergy that serves progress in the subject of gerodontology.
