Occurrence of the various forms of Carabelli's trait on maxillary first permanent molars was studied in 376 Indian students at Manipal, Karnataka, a state in south India. The trait was found absent in 64.4% of the teeth studied. Slight tubercles were found more often than pronounced tubercles and more tubercles were found in males than females; conversely the absence of the trait was observed more often in girls than boys. The sample was divided into two groups. Group I consisted of North Indians and Group II consisted of South Indians. Variations in occurrence of the trait between North Indian and South Indian students were studied and it was found to occur almost equally in both groups. The study was extended to observe variations in occurrence of the trait between Indian students of Indian and Foreign nationality but no significant variation was observed.
在印度南部卡纳塔克邦马尼帕尔市的376名印度学生中,研究了上颌第一恒磨牙上各种形式的卡氏特征的出现情况。在所研究的牙齿中,64.4%未发现该特征。轻微结节比明显结节更常见,男性比女性发现的结节更多;相反,女孩比男孩更常观察到该特征的缺失。样本分为两组。第一组由北印度人组成,第二组由南印度人组成。研究了北印度和南印度学生该特征出现情况的差异,发现两组中该特征的出现情况几乎相同。该研究进一步扩展,以观察印度国籍和外国国籍的印度学生该特征出现情况的差异,但未观察到显著差异。
