“…Case reports which have been published earlier have suggested that the supplemental teeth may exhibit deep palatal pits and coronal invaginations, or that when no morphological abnormalities are noted, the tooth with minimum measurement among other anterior teeth is regarded as supernumerary one [5,6]. Interestingly, in our case, both these features stood irrelevant.…”

“…A possible association between supernumerary teeth and aggressive periodontitis has been described, though it is uncommon [9]. Reports made by Odell and Hughes in 1995, attributed them to have familial tendencies, with rare occurrences [6,11,14,15]. Our patient reported to us with periodontitis which was generalized and hence, the existence of aggressive periodontitis was ruled out.…”

“…Maxillary premolar, maxillary canine and mandible fourth molar are the least common ones. Approximately 90-98% of all supernumerary teeth occur in the maxilla, with a observed and immediate treatment should be instituted, if any pathology arises in any instance [4][5][6]9,12,13].…”

A 34-year-old man reported to the Department of Oral Medicine and Radiology, Educare Institute of Dental Sciences, Malappuram, Kerala, India, with chief complaints of bad breath and mobile lower front teeth, which were there since 2 years.The family and medical histories were non-contributory. There were no signs of any identified syndrome.On intra-oral examination, he was found to have severe calculus, generalized cervical abrasion and generalized periodontitis, with mobility with respect to lower incisors. A careful examination revealed five incisors in the mandibular anterior region. All five incisors were separate, with well formed morphologies [Table/ Fig-1, 2] show five mandibular incisors which are well formed and separate -frontal and occlusal views respectively.To distinguish between them, the following steps were adopted. During examination, the median area was defined positionally by the inferior labial frenum and radiographically by the genial tubercle; it appeared that the supernumerary tooth was more towards the right side from the midline. Upon carefully examining all 5 incisors clinically and radiographically, a conclusion was drawn that the distal most incisors on either side of midline were normal lateral incisors, as their crown measurements were greater than those of the remaining 3 incisors. Distinguishing the supernumerary tooth among the 3 incisors was quite challenging, as crown measurements of all the 3 were found to be roughly the same. Since the second incisor from left showed a marked rotation and thereby caused crowding, with the presence of labial frenum just in front of the incisor, it was concluded that the tooth positioned centrally was the supernumerary one. A final diagnosis of mandibular mesiodens of supplemental type and chronic generalized periodontitis was made. aBstRaCtDevelopmental anomalies affecting the number of teeth are occasionally encountered clinically. The incidence of super numerary teeth is approximately 1-3%. Among these are the maxillary anterior teeth, the maxillary molars, and the maxillo-mandubular premolars, in terms of descending order of occur rence. Supernumeraries occur rarely in the mandibular anterior teeth region. They may be either supplemental or rudimentary. We are reporting case of a supplemental type of supernumerary tooth in the mandibular anterior region and steps which were followed to distinguish supernumerary tooth from the normal series.

“…A male to female ratio of 2:1 is found in populations with single supernumerary teeth [Kantor et al, 1988] which increases to 3:1 for multiple supernumerary teeth [Gibson, 1979]. Although inherited forms are rare, a familial inheritance has been reported that can be autosomal dominant with incomplete penetrance, autosomal recessive [Cassia et al, 2004] or sex linked pattern of inheritance [Burzynski and Escobar, 1983]. …”

Dental anomalies are common congenital malformations that can occur either as isolated findings or as part of a syndrome. This review focuses on genetic causes of abnormal tooth development and the implications of these abnormalities for clinical care. As an introduction, we describe general insights into the genetics of tooth development obtained from mouse and zebrafish models. This is followed by a discussion of isolated as well as syndromic tooth agenesis, including Van der Woude syndrome, ectodermal dysplasias, oral-facial-digital syndrome type I, Rieger syndrome, holoprosencephaly, and tooth anomalies associated with cleft lip and palate. Next, we review delayed formation and eruption of teeth, as well as abnormalities in tooth size, shape and form. Finally, isolated and syndromic causes of supernumerary teeth are considered, including cleidocranial dysplasia and Gardner syndrome.
