Paradental cyst associated with supernumerary tooth fused with third molar: A rare case report.

Prakash AR, Reddy PS, Rajanikanth M - J Oral Maxillofac Pathol (2012)

Bottom Line: There is no difference between men and women in incidence.A history of recurrent pericoronitis is reported usually and there is often the presence of a communication between the periodontal pocket and the cyst.We present a rare case report where in partially erupted mandibular third molar is fused horizontally with a supernumerary tooth with paradental cyst.

ABSTRACT
Fusion is the union of two tooth buds that are normally separated. Fusion is more frequent in deciduous teeth, particularly in the anterior region. The etiology of fusion is not known. It has been suggested that the pressure of adjacent dental follicles produces their contact and fusion before calcification. There is no difference between men and women in incidence. The term paradental cyst means that such type of cysts that are close proximity with the root of a tooth. A history of recurrent pericoronitis is reported usually and there is often the presence of a communication between the periodontal pocket and the cyst. We present a rare case report where in partially erupted mandibular third molar is fused horizontally with a supernumerary tooth with paradental cyst.

Figure 2: (a and b) Gross specimen showing fusion of the third molar and supernumerary tooth and enamel displayed from the apical aspect

Mentions: Radiographically, the anomaly appeared as unilocular radiolucency at the apical portion of the supernumerary tooth. The pulp chamber of both teeth appeared separate. Differential diagnoses for the radiopacity considered were supernumerary tooth and odontoma, and for the radiolucency the paradental cyst was considered. The partially impacted tooth along with the supernumerary tooth was removed surgically under LA and the healing was uneventful. Examination of the gross specimen showed that the supernumerary tooth was horizontally fused with the third molar [Figure 2a] and when viewed apically the enamel of the supernumerary tooth was clearly seen [Figure 2b]. Intra oral periapical radiograph was taken of the gross specimen [Figure 3]. The gross specimen was cut into equal halves and seen under stereo microscope. The dentin was continuous of both the impacted third molar and the horizontal supernumerary tooth in one area and confirmed the diagnosis of fusion [Figure 4]. When the soft tissue surrounding the supernumerary tooth seen histologically, the epithelial lining was made up of 2–4 layers resembling reduced enamel epithelium [Figure 5]. Few areas there were hyperplastic nonkeratinized squamous epithelium. A heavy inflammatory infiltrate of mononuclear and polymorphonuclear cells was observed in the epithelium and connective tissue wall [Figure 6]. The fibrous wall showed multinucleated giant cells associated with the thickness of the blood vessel walls. The histopathology associated with macroscopic and radiographic examinations permitted the definitive diagnosis of a paradental cyst of the partially impacted mandibular left third molar fused to supernumerary tooth.
