The extra tooth present in the dental arch is called as supernumerary tooth (ST) tooth and when the extra tooth which is similar to the adjacent teeth is called as supplemental tooth. It results from the abnormal instruction received during odontogenesis. These teeth are extra in the arch or unerupted. When it remains unerupted, it may cause disturbance to the developing teeth. In this case the patient approached for psychological (cancer- phobic) reason for the treatment. This case is also interesting because of presence of ST between upper first and second molar, which has rare in occurrence and is termed as “paramolar tooth”. The supernumerary tooth was extracted under local anesthesia.

  Introduction: Top

Development of the tooth is a continuous process with a number of physiologic and morphological stages. The interaction of complex processes results in final shape and size of a tooth. Any Interference with the stage of initiation, may result in single or multiple missing teeth (hypodontia or oligodontia respectively) or extra tooth/teeth (supernumerary teeth)[1],[2]. A supernumerary tooth is one or more teeth in the arch[3]. The term mesiodens means a supernumerary tooth that is located between the maxillary central incisors[4],[5]. In the primary dentition, the incidence is said to be 0.3%-0.8% and in the permanent dentition 1.5%-3.5%[6],[7]. The low prevalence of ST in primary dentition is lower because it is under reported[7], because the supernumerary teeth are often of normal shape and size to the deciduous teeth, appears normal[9]. The most common location of supernumerary teeth is between maxillary teeth and least in posterior dental arch. Supernumerary teeth can be classified, based upon the position of shape and position of teeth. The shape includes; tuberculate, conical (also called “peg shaped”); multiple small tooth-like forms and complex odontoma (a disorganized mass of dental tissue). When classified by position, a supernumerary tooth may be referred to as a mesiodens, a paramolar, or a distomolars.[2],[3],[10]. The paramolar are very less frequent (only 9.0% as compared to maxillary mesiodens 91%[5]. The fourth and fifth molars that form behind the third molars are another kind of rare extra teeth (supernumerary teeth).[7],[10]

  Case Report: Top

A male patient aged 22 years old from Jharkhand, who came to the dental out door of Indira Gandhi Institutes of Medical Sciences, Sheikhpura, Patna with complain of tumor in the upper back region of the oral cavity. He and his father were frightened. He went for treatment to local doctor in the city. But he was not satisfied with the doctor advice and hence reported to the dental outdoor of, IGIMS, Patna, Bihar. The oral findings revealed one extra erupted tooth (paramolar) between the upper left permanent second and third molar. On palpation it seems firmly adhered to the underlying structures. The remaining part of the oral structures appears normal. The routine blood estimation, bleeding and clotting time were normal and panoramic radiographic (OPG) reveals partially erupted paramolar.

  Managements: Top

It was decided to extract the tooth under local anaesthesia after taking consent. The extraction was done and bleeding was arrested with the help of cotton roll packed. The patient was given necessary instructions and was prescribed analgesics. A week long follow-up showed healed wound.

  Discussion: Top

It is essential not only to enumerate but also to identify the supernumerary teeth (ST) present clinically and radio- graphically before a definitive diagnosis and treatment plan can be formulated[8]. The presences of S.T In the posterior regions are rare and usually patients and doctor may confuse for some other pathology. This is because of rare occurrence of paramolar in the clinical practice and reported less in literature[4],[5].

  Conclusion: Top

The extracted tooth was paramolar, a rare type of supernumerary teeth.
