“…This supports the findings of other researchers (Alvesalo et al, 1975;Falomo, 2002;Joshi, 1975;Rusmah, 1992;Thomas et al, 1986); which they agree that bilateralism of the trait is more frequent. Although some investigators, such as Biggerstaff (1973Biggerstaff ( , 1972, suggested that bilateralism or mirroring is not a factor in the Carabelli trait, even among twins.…”

The Carabelli cusp is a tubercle or cuspule, or a groove often seen on the palatal surface of the mesiopalatal cusp of maxillary permanent molars and maxillary second deciduous molars. The purpose of this study was to determine the prevalence, degree of expression of the Carabelli structure, and caries prevalence in the Carabelli structure in the permanent first and second maxillary molars in selected Saudi population. Two hundred and seventy six Saudi patients attending the college of dentistry clinics at King Saud University in Riyadh city were selected for examination. The patients' age ranged from 11 to 55 years old. Patients with severely carious, restored or missing upper first or second maxillary molars on any side were excluded. Both the first and the second upper molars were carefully examined for the occurrence of the Carabelli structure and the presence of caries. The prevalence of the Carabelli structure was 57.6% with a bilateralism of 91.2% in the first maxillary molars and 86.4% in the second molars. The Carabelli structure was found to be 29.7% as a groove expression, and 35.5% as a cusp expression. It was concluded that more than half of the Saudi population have a degree of expression of the Carabelli structure and the Carabelli trait is associated with increased caries incidence. Clinical relevance: Prominent pits and grooves can be foci for plaque retention and caries development, a large tubercle can pose some problems with orthodontic bands.

“…The morphological crown traits did not display significant sex differences, as has been previously reported for Carabelli's trait [58,59] and molar cusp number [34]. Aside from the lack of sexual dimorphism in Carabelli's trait, the trend of greater expression in males than females may not be adequately described by the current method.…”

“…All the methods available to score Carabelli's trait were created for the permanent dentition, which differs in its expression of the trait compared to the deciduous dentition. As seen in this study and others the deciduous dentition has a propensity of the groove or Y-shaped Carabelli's phenotype, and the permanent dentition displays a cuspal from [58][59][60]. A method to score Carabelli's trait in the deciduous dentition would be more suitable if it provided a greater number of scores representing the groove and Y-shaped expressions.…”

SUMMARY:The cusp of Carabelli trait was first described by Carabelli in 1842. If present, it is seen on the mesial aspect of the mesiopalatal cusp of the deciduous maxillary second molar or permanent maxillary first, second and third molar. The level of expression varies from a mere pit or groove to a well developed cusp. The objective of this study was to assess the prevalence of this trait in Abha Secondary School boys in the age range of 15-20 years. 917 subjects without caries or fillings (or missing) in permanent upper first (16/ 26) and second molars (17/27) were selected out of the 3408 students examined. The trait was recorded as present or absent in 16/26 and 17/27 only as most of the students had erupted premolars and unerupted third molars. The trait was present in 41.7% of the population out of which 82.2% were seen on 16/26 bilaterally. It showed more predilection to permanent maxillary right first molar -39.4% than permanent maxillary left first molar -35.8%. Only 3.1% of the population had the trait on 17/27. These results are in contrast with the prevalence studies carried out in Riyadh -57.6% and Jeddah -58.7%. Nevertheless, it places the Saudi population in moderate CT prevalence group.
