Hyperdontia is a condition with excess number of teeth than normal. It may be seen in both primary and permanent dentition, but less frequently in primary teeth. Occasionally, it is found to be fused with the adjacent normal tooth. This paper reports a case of a supernumerary tooth in the maxillary anterior region fused with primary central incisor along with the etiological factors and management. Key words: Fusion, Hyperdontia, maxilla, primary dentition.

Email: nimskrishna2007@gmail.com Introduction Development of the tooth is a continuous process with a number of physiologic growth processes and various morphologic stages interplay to achieve the tooths final form and structure. Interference with the stage of initiation, a momentary event, may result in single or multiple missing teeth (hypodontia or oligodontia respectively) or supernumerary teeth 1 . A supernumerary tooth is one that is additional to the normal series and can be found in almost any region of the dental arch 2 . In the primary dentition, the incidence is said to be 0.3%-0.8% and in the permanent dentition 1.5%-3.5%3.There is no significant sex distribution in primary supernumerary teeth; however, males have been shown to be affected more in the permanent dentition than females. Tooth fusion is defined as union between the dentin and/ or enamel of two or more separate developing teeth 4,5 . Fusion may occur between two normal teeth or between a normal tooth and a supernumerary tooth. Clinically, fused anterior teeth have a groove or notch on the incisal edge that goes buccolingually and radiographical findings reveal the fused dentin in some region with separate pulp chambers and canals. This article reports a case of supernumerary tooth fused with primary central incisor. Case report A female child age 8-years, reported to the department of Paedodontics and Preventive dentistry, Narayana Dental College and Hospital, Nellore accompanied by her father in March 2010 for a routine dental check up and scaling. Intra oral examination revealed mixed dentition stage with a supernumerary tooth fused to primary right central incisor. Primary central incisor and the supernumerary teeth showed proximal carious lesions (Figure1). An Orthopantomograph confirmed the presence of supernumerary tooth fused with the primary right central incisor joined by dentin Archives of Dental Sciences, Vol.2, Issue 3, 37-39 http:www.archdent.org © Archives of Dental Sciences Vol.2, Issue 3, 37-39 http:www.archdent.org Fig 1: Intra oral picture showing supernumerary tooth between primary central and lateral incisor. , Dedeepya P 2
