Abstract：
Aim This study aims to evaluate the non-morphological traits of the South Indian population. Introduction Dental morphological traits, also known as non-metric dental traits, exhibit variation in appearance both within and between groups. The study analyzed the non-metric traits among the South Indian population, as few variants can be grouped within the population. Materials and methods A total of 500 extracted tooth samples were collected. The dental non-metric traits that were evaluated are the cusp of Carabelli (CC), Talon\'s cusp (TC), shoveled incisor (SI), peg-shaped lateral incisor (PL), protostylid (PR), Dryopithecus pattern groove (DP), hypoconulid (HY), parastyle (PA), multiple parastyle (MPA), paracone (PC), Bushman\'s canine (BC), interruption groove (IG), tuberculum dentale (TD), tuberculum intermedium (TI), radix entomolaris (RE), fusion (F), radiculous premolar (RP), dilaceration (D), dens evaginatus (DE), and enamel pearl (EP). Results Out of 20 dental non-metric traits that were evaluated in the study, 14 traits were identified to be common within the population. The prevalence were as follows: cusp of Carabelli (52%), shoveled incisor (8.2%), peg-shaped lateral incisor (7.4%), parastyle (0.8%), multiple parastyle (0.2%), Bushman\'s canine (0.4%), interruption groove (2.2%), tuberculum intermedium (0.6%), radix entomolaris (39.6%), fusion (2.8%), radiculous premolar (0.2%), dilaceration (58.2%), dens evaginatus (1.2%), and enamel pearl (0.8%) among the South Indian population. Conclusion The current study was discovered to have more Carabelli traits, shoveled incisors, radix entomolaris, and dilaceration than other non-metric features. This shows that these characteristics are more prevalent in the South Indian population, which could be one of the strategies used to validate human identification in a forensic context.
摘要：
目的本研究旨在评估南印度种群的非形态特征。引言牙科形态性状,也被称为非度量牙齿特征，表现出群体内部和群体之间的外观变化。这项研究分析了南印度人口的非计量特征，很少有变体可以在人群中分组。材料和方法收集总共500个拔出的牙齿样品。评估的牙齿非度量特征是卡拉贝利(CC)的尖点，爪子尖头（TC），铲门牙（SI），钉形侧切牙（PL），原型（PR），Dryopithecuspatterngorter(DP),阴囊不足（HY），parastyle(PA),多个半工艺（MPA），paracone(PC),布什曼犬（BC），中断槽(IG),结节（TD），中间结节(TI),天蚕(RE)，融合（F），牙根前磨牙(RP),撕裂(D),densevaginatus(DE)，和搪瓷珍珠（EP）。结果在研究中评估的20个牙齿非度量特征中，鉴定出14个性状在种群中是常见的。患病率如下：Carabelli的尖点（52％），铲门牙(8.2%),钉形侧切牙（7.4%），parastyle(0.8%),多个半曲率(0.2%)，布什曼犬（0.4%），中断槽(2.2%),中间结节（0.6%），天花(39.6%)，融合（2.8%），牙根前磨牙（0.2%），撕裂伤（58.2%），窝点(1.2%)，南印度人口中的搪瓷珍珠(0.8%)。结论目前的研究发现有更多的Carabelli特征，铲门牙，天蚕,和撕裂比其他非度量特征。这表明这些特征在南印度人口中更为普遍,这可能是在法医背景下验证人类身份的策略之一。
