ABSTRACT:
The lateral periodontal cyst (LPC) is a harmless developmental aberration derived from pulp infection, infectionthrough the gingival crevice or odontogenic epithelia lying between the roots of vital teeth. The designation 'lateral periodontal cyst' is confined tothose cysts that occur in the lateral periodontal position. Standish and Shafer (1958) commented that the lateral periodontal cyst was of varied aetiology but that the term 'lateral periodontal cyst' should be used to indicate all cysts developing in the anatomical region of the lateral periodontium. The purpose of this article is to report a case of lateral periodontal cyst, presenting with typical clinical features, review the relevant literature which describes the etiopathogenesis, radiological histopathological features and successful surgical therapyof lateral periodontal cysts.
Keywords- Lateral Periodontal Cyst, Etiopathogenesis of LPC, Odontogenic cysts.
INTRODUCTION
Odontogenic cysts are classified by the World Health Organization as inflammatory and developmental according to their epithelial lining. The LPC is a developmental odontogenic cyst defined as a radiolucent lesion which develops along the lateral aspect of an erupted vital tooth.1 The most frequent site of origin of LPC is the premolar region of the mandible, followed by the anterior segment of the maxillary alveolar process. LPC arise preferentially in individuals aged between 40 to 70 years, irrespective of gender.2 Neville et al reported that 75 to 80% of cases occur in the region of the lateral incisor, canine and lower pre-molar. The present case also have been reported in anterior mandibular area.3
CASE REPORT- A 25 years old female patient, referred to our college with complain of pain and swelling in right lower anterior region since 2 years, which gradually increasing. Intraorally the solitary palpable swelling, which was present labial vestibular area in relation to right mandibular canine and premolar regions (Pic- 1). Radiographically, well defined radiolucency was observed in the lateral aspect of mandibular canine root area, measuring approx 2x2cm, which caused displacement of right mandibular canine and premolar teeth (Pic-2). The lesion was enucleated under local anesthesia...
