There are various treatment modalities for dentigerous cysts. However, when preservation of the tooth is desirable, then marsupialization is the treatment of choice. We present a rare case of a 15 year old female patient with a cystic space associated with impacted right maxillary central incisor. The cyst was marsupilised. The histopathology report confirmed the dentigerous cyst. Tooth erupted in the oral cavity after surgical exposure which was followed by minor orth- odontic traction. The impacted permanent central incisor became vertical from labially horizontal position in 6 months. Introduction Dentigerous cyst can be defined as an odontogenic cyst that surrounds the crown of an impacted tooth; caused by fluid accumulation between reduced enamel epithelium and the enamel surface, resulting in a cyst in which the crown is located within the lumen [2]. The cyst nearly always involves or is associated with the crown of a normal permanent tooth [1,2]. In this case report dentigerous cyst was marsupilised for the surgical exposure of crown of horizontally labially impacted central incisor, followed by a follow up of the patient who is currently undergoing orthodontic treatment. Case Description A 15 years old female patient consulted for missing maxillary central incisor associated with a gap between the upper front teeth. She also had a past dental history of extraction of a deciduous incisor in the same region about one month back. Her preoperative CBCT images revealed a hyperplastic dental follicle associated with horizontal labially impacted right maxillary central incisor below the nasal floor with well formed roots in the bony socket. The incisal edge was found to be located 3.8 mm above the alveolar crest with the middle and apical third of the root surface contagious with the nasal floor. The follicular space around the crown of the tooth appeared enlarged with mild buccal cortical expansion. There was no breach in nasopalatine canal. There was a discontinuity towards the alveolar crest. Therefore, CBCT impression was horizontal labially impacted right central incisor with hyperplastic dental follicle Her presurgical blood investigations were normal, so the surgical exposure of crown of impacted tooth was done and the surrounding soft tissue was removed under local anesthesia. Tissue specimen was sent to the Oral Pathologist for histopathological analysis. The histopathology report showed the presence of cystic cavity lined by squamous epithelium with underlying thin connective tissue wall and was concluded as dentigerous cyst. The patient was instructed to irrigate the cystic space with sterile saline three times a day and advised to maintain hygiene. She was advised orthodontic treatment and regular follow up by the Oral Surgeon. The orthodontic traction was applied by the Orthodontist (Figure 3). Her postoperative follow up pictures are shown in figures.
