“…These features, characteristics and occupational marks give an idea about the habits and cultural practices of a group of people/ethnicity. The dental characteristics such as the shovelling or scooping of the upper incisor (most common in Asiatic Mongoloids and Amerindians), taurodontism, chisel shaped incisors, Carabelli’s cusp, hypocone, and protostylid, peg shaping of the teeth can be used to determine the ethnicity of the individual [ 36 - 38 ]. According to Vij [ 8 ], Aborigines Australians, the Melanesians and the American Indians and Eskimos tend to be large toothed races with wide crowns and Lapps and Bushmen are small people with comparatively smaller teeth.…”

Forensic odontology is primarily concerned with the use of teeth and oral structures for identification in a legal context. Various forensic odontology techniques help in the identification of the human remains in incidents such as terrorists’ attacks, airplane, train and road accidents, fires, mass murders, and natural disasters such as tsunamis, earth quakes and floods, etc. (Disaster Victim Identification-DVI). Dental structures are the hardest and well protected structures in the body. These structures resist decomposition and high temperatures and are among the last ones to disintegrate after death. The principal basis of the dental identification lies in the fact that no two oral cavities are alike and the teeth are unique to an individual. The dental evidence of the deceased recovered from the scene of crime/occurrence is compared with the ante-mortem records for identification. Dental features such as tooth morphology, variations in shape and size, restorations, pathologies, missing tooth, wear patterns, crowding of the teeth, colour and position of the tooth, rotations and other peculiar dental anomalies give every individual a unique identity. In absence of ante-mortem dental records for comparison, the teeth can help in the determination of age, sex, race/ethnicity, habits, occupations, etc. which can give further clues regarding the identity of the individuals. This piece of writing gives an overview of dental evidence, its use in forensic identification and its limitations.

“…As the supernumerary molars in our case are in still follicular developing stage and patient had no discomfort or symptoms associated with supernumerary molars, hence no treatment was advised but the patient was instructed to attend for regular follow ups every six months' interval so that final path of eruption, eruption pattern, their final position in the dental arch can be evaluated. [5,6]. This structure is usually present on the buccal surface of the mesiobuccal cusp (paracone) and rarely on the distobuccal cusp (metacone).…”

Supernumerary molars are relatively rare entities in maxillofacial region which can be classified broadly into distomolars and paramolars. Usually these occur singly and unilaterally. Occurrence of both paramolar and distomolar together is a very rare finding. This paper reports an unusual occurrence of combination of developing unerupted paramolar and distomolar follicles in the maxilla which was an incidental finding in the Orthopantamograph of a 13 year old girl. Patient was asymptomatic, hence was kept under observation and follow up. This paper describes the incidence and prevalence, possible etiological factors, complications, treatment options for supernumerary molars along with review of literature.

“…It has been reported that the presence of protostylid in primary molars is a predilection for its presence in permanent molars. 7 In our case, the parents were unaware of the presence of such an extra cusp in the primary molar and so we could only assume regarding its presence in the primary dentition.…”

Aim:The aim of this case report is to present a rare finding of protostylid on the mandibular second molar.Background: Human teeth of both primary and permanent dentitions sometimes shows developmental malformation which results in alteration of their size, shape and structure and especially with the crown either in the form of anomalous cusps or an increase in the number of cusp. A protostylid is a supernumerary or accessory cusp found on the molars on the mesial half of the buccal surface.Case discussion: This case report presents a rare finding of protostylid on the buccal surface of the permanent left second molar tooth in a 12 year old female patient. There was no similar finding seen on the other teeth and in other members of the family. Conclusion:The dental polymorphisms described in this case report is some of the rarest and unique forms of the human dentition. Thus, the reporting and preservation of these structures can be important from the perspective of forensic odontology.Clinical significance: Though this may not pose significant problem in most instances but its finding is of very much significant interest from the perspective of forensic dentistry.
