          Abstract

          Talon cusp is an accessory cusp similar to a projection, extending from the cingulum or cemento-enamel junction to the incisal edge. It occurs on labial or palatal surfaces of primary or permanent anterior teeth in both arches. This accessory cusp can occur as an isolated entity or in association with other dental anomalies. Occurrence of a talon cusp on supernu-merary teeth is rare and uncommon. This paper reports an unusual case of a talon cusp on a supernumerary tooth in association with mesiodens.

            Clinical orodental abnormalities in Mexican children.

            A total of 32,022 Mexican children (16,473 boys, 15,549 girls) were examined for several congenital oral and paraoral anomalies. The findings for commissural lip pits (boys 53.1, girls 52.4 per 1000) are less than those reported for adults. This may indicate that pits become accentuated with age. Fordyce granules were seen with a prevalence of 1.2 per 1000. This is in contrast to the reported 85.6% prevalence for the adult population, also possibly reflecting increased manifestation with increased age. Our data for exogenous tooth pigmentation show increased prevalence with age (group I [5 to 10 1/2 years], 9.8%, versus group II [10 1/2 to 14 1/2 years], 12.9%), possibly indicating decrease in attention to oral hygiene. The prevalence of talon cusp was found to be 0.6 per 1000, and for ankyloglossia 8.3 per 1000. Prevalence values for bifid tongue are reported for the first time, indicating one affected per 187 children examined. The prevalence of fissured tongue (15.7%) shows a statistically significant difference between boys (16.8%) and girls (14.5%). The prevalence of geographic tongue (1.9%) shows a marked difference between group I (2.2%) and group II (1.2%).

              Talon cusp--clinical significance and management: case reports.

              Talon cusp is a rare dental anomaly manifested as an accessory cusplike structure on the tooth crown. This article reports four cases of talon cusp that caused clinical problems related to appearance, occlusal interference, tooth displacement, caries, and tongue irritation. The cases presented were associated with other dental abnormalities, suggesting per se that genetic inheritance may be the causative factor. Clinical and radiographic characteristics of this developmental anomaly and modes of treatment are described.
