“…The statistically significant inter-relationship between Carabelli's trait and shoveling was demonstrated by other investigators [45,46] and it was supported by the present work ( Table 7). The prevalence of Carabelli's trait has been reported to be higher in males than in females in the permanent dentition [42,[47][48][49][50]. However, gender difference was not found in this study ( Table 1).…”

Aim: To investigate the prevalence of four major dental traits in the southern Chinese permanent dentition and to compare these with studies from different populations. Materials and Methods: The material used in the study consisted of high quality study models collected from 725 randomly selected 12-year-old children in Hong Kong (358 males and 367 females). The various traits were assessed using standard diagnostic criteria. Literature and data related to dental traits in the permanent dentition were sourced using PubMed and hand searches. Results: The mouth prevalence of shovelling, lingual tubercle, Carabelli's trait, and protostylid were 80.4%, 38.9%, 50.5% and 37.5% respectively. The prevalence figure for the cusp type of Carabelli's trait in this study (23.7%) was higher than for other Mongoloids. The prevalence figures for semi-shovel shaped maxillary incisors (42.6% to 48.6%) and the cusp type of protostylid trait in mandibular molars (10.1%) were higher than for any other populations. Conclusion: The higher prevalences of semi-shovel shaped maxillary incisors, and protostylid cusp on the mandibular molars can be considered to be characteristics of the southern Chinese permanent dentition.

Aim: To investigate the dental morphology of incisors of the Southern Chinese and compare these with studies in different populations. Materials and Methods: The dental morphology of study casts of an unselected sample from a 12 year old Hong Kong Oral Health Survey of 12 year old children (n=459; 295 boys and 164 girls) were studied. Results: The moderate types of shovel-shaped central incisors were prevalent in the Southern Chinese, whereas the pronounced type of shovel-shaped incisors were more prevalent in the Taiwan Chinese. Conclusion: The Southern Chinese shows a lesser degree of shoveling than the other Chinese populations.

“…A similar result for Carabelli trait was reported by Salako and Bello[ 6 ] among Saudi Arabian children and King et al .,[ 7 ] among Southern Chinese in Hong Kong. However, this finding is in contrast to studies conducted among Chinese population that reside in Southern Taiwan, by Hsu et al .,[ 8 ] and in University of Franca, Franca, Brazil by Ferreira et al .,[ 3 ] where Carabelli trait were more observed in males.…”

Purpose:In a country like India, in addition to the great innate diversity, there are distinct migrant populations with unique dental traits.Aim:To assess the distribution and degree of expression of cusp of Carabelli of maxillary first permanent molars and shoveling trait of maxillary central incisors, between three ethnic groups of Coorg, namely Kodavas, Tibetans, and Malayalees.Materials and Methods:A cross-sectional, indirect, anthropometric, study was carried out among 15- to 30-year-old subjects belonging to three different ethnic origins. A random sample consisting of 91 subjects were recruited for the study. The shovel trait of incisors and the Carabelli trait of molars were recorded according to the classification given by Hrdliƈka and Sousa et al., respectively.Statistical Analysis:The Kruskal-Wallis test was employed to determine the difference in three populations for shoveling and Carabelli traits. Mann-Whitney Test was used for pair-wise comparisons of three populations.Result:Of the total 91 subjects, 31 were Kodavas, 30 Malayalees and 30 Tibetans. There was a statistically significant difference in shoveling trait among the three ethnic groups. For Carabelli traits, there was no statistically significant difference among three ethnic groups.Conclusion:The present study findings showed that Tibetans have a higher degree of shoveling trait than the selected South Indian ethnic groups.
