Non-metric Dental Crown Traits are a principal source of information in forensic dentistry. However, inadequate data on the prevalence of these traits prompted this study to determine the frequency, sexual dimorphism and degree of inter-trait association in two different populations of India. Dichotomized data on the existence of non-metric features were recorded among individuals from Odisha (n=506) and Kerala (n=536) between 15 to 30 years of age. Cusp of Carabelli is the most common trait to occur (48 %) followed by shovelling of incisors (15%) and Bushman canine (14%). Bushman canine (p=0.045) and Cusp of Carabelli (p = 0.041) were found to be significantly expressed in Odisha and Kerala populations respectively. A strong association between shovelling of central incisor and Bushman canine with a likelihood ratio of 14.041 (p=0.001) was observed. This study will help in characterizing the Indian dentition and post-mortem dental profiling.
非测量性牙冠特征是法医牙科学的主要信息来源。然而，关于这些特征流行率的数据不足促使本研究确定印度两个不同人群中这些特征的频率、性别二态性和特征间关联程度。在年龄在15至30岁之间的奥里萨邦（n = 506）和喀拉拉邦（n = 536）的个体中记录了关于非测量特征存在与否的二分数据。卡氏尖是最常见的特征（48%），其次是铲形门齿（15%）和布须曼犬齿（14%）。发现布须曼犬齿（p = 0.045）和卡氏尖（p = 0.041）分别在奥里萨邦和喀拉拉邦人群中显著表达。观察到中央门齿铲形与布须曼犬齿之间存在强关联，似然比为14.041（p = 0.001）。本研究将有助于描述印度牙列特征和死后牙齿分析。
