ABSTRACT Mucocele are common salivary gland disorder which can be present in the oral cavity, appendix, gall bladder, paranasal sinuses or lacrimal sac. Common location for these lesions in oral cavity is lower lip however it also presents on other locations like tongue, buccal mucosa, soft palate, retromolar pad and lower labial mucosa. Trauma and lip biting habits are the main cause for these types of lesions. These are painless lesions which can be diagnosed clinically. In this review, a method used for searching data includes various internet sources and relevant electronic journals from the Pub Med and Medline. Keywords: Mucocels, Lower lip, Retention cyst. INTRODUCTION Mucocele is defined as a mucus filled cyst that can Types appear in the oral cavity, appendix, gall bladder, paranasal sinuses or lacrimal sac (Baurmash, 2003; Clinically there are two types, extravasation and retention Ozturk et al., 2005).

The subepithelial connective tissue graft (SCTG) is a highly predictable procedure with low complication rate. The reported early complications consist of typical postsurgical sequelae, such as pain and swelling. This case report describes the development and management of a gingival cyst following SCTG to obtain root coverage. Three weeks after SCTG procedure, a slightly raised, indurated, ∼5 mm diameter asymptomatic lesion was evident. Excisional biopsy was performed and the histopathological evaluation confirmed the gingival cyst diagnosis. At the 1-yearollow-up, f the site had complete root coverage and normal tissue appearance and the patient remained asymptomatic. 1.

The process of clinical diagnosis and treatment planning is of great concern to the patient as it determines the nature of future follow up care. There is a strong need for a rational and functional classification which will enable better understanding of the basic disease process, as well as in formulating a differential diagnosis. Clinical diagnostic skills and good judgment forms the key to successful management of yellow lesions of the oral cavity.
