“…Many studies on primary dentition in children have focused on reporting dental anomalies, such as supernumeraries [1], mesiodens [2], hypodontia [3], taurodontism [4], dens in dente [5], talon cusp [6], dysplasia [7], fusion [8], and double teeth [9]. Malocclusion in the primary teeth is not uncommon, and it usually stems from environmental factors, such as digit sucking and trauma.…”

Objective: To study occlusal features and their relation to caries experience in Hong Kong Chinese preschool children. Methods: Seven kindergarten classes in Hong Kong were selected using a stratified random sampling method, and the 4- and 5-year-old Chinese kindergarten children were invited to join the survey. Two calibrated dentists performed the clinical examinations in the kindergartens. Occlusion features, including incisal overjet; canine and molar relationship; median diastema; and primate space as well as malocclusion features, including crossbite; anterior open bite; and scissor bite, were recorded. Caries experience was recorded with the dmft index. Results: A total of 538 children were invited to participate in the study, and finally 495 children were examined (92%). Approximately half (52%) had a normal incisor relationship. Most children had a class I canine relationship (left-79%; right-75%). Approximately two-thirds had a flush terminal plane (left-64%; right-65%). Most children (76%) had a maxillary primate space, and 47% had a mandibular primate space. The prevalence of median diastema, anterior crossbite, and unilateral posterior crossbite was 30%, 12% and 1%, respectively. No bilateral posterior crossbite or scissor bite was found. Approximately half (49%) had caries experience. The mean dmft score was 2.1. Gender and age were not associated with either the studied occlusal features or the mean dmft score (p > 0.05). Conclusion: Approximately half of the Hong Kong preschool children studied had a normal occlusion, and two-thirds of them had a flush terminal plane. About three-quarters of them had a maxillary primate space, and half of them had a mandibular primate space. Their occlusal traits were not associated with caries experience and prevalence.

“…Increased incidence of talon cusps has been observed in patients with Mohr syndrome, SturgeWeber syndrome, Rubinstein-Taybi syndrome, Incontinentia pigmentii Achromians, Ellis van creveld syndrome, and Alagille's syndrome. 7,12 The true etiology of both these dental anomalies has not been exactly reported in the literature. Double tooth may be complete or incomplete, depending on the stage of tooth development at the time of union, with one normal and the other may be supernumerary teeth or conjoint tooth bud.…”

“…Trauma and other localized forces on tooth germ have also been held responsible for talon cusp [2,4,10]. Lee proposed that hyperactivity of cells of tooth germ may lead to development of talon cusp, which is genetically determined but the degree is influenced by environmental factors [16].…”

Introduction: talon cusp is a well delineated accessory cusp projecting from the cingulum area of an anterior tooth. It is named so due to its resemblance with eagle's talon, which is the shape of eagle's claw when hooked on to its prey. Various alterations in shape in talon's cusp may be present like it may be either sharp or spiked, teat like or may have rounded and smooth tips. Only two cases have been reported in Indian population till date. case report: Hereby, we report a unique case of talon's cusp in a fouryear-old boy. conclusion: the occurrence of talon's cusp in mandibular primary dentition is extremely rare.
