Dermatoglyphics can prove to be an extremely useful tool for preliminary investigations in conditions with a suspected genetic base. Since caries is a multifactorial disease with the influence of genetic pattern, early prediction for high-risk children can help in using effective and efficient caries preventive measures that are a part of the pedodontist arsenal.
This study was done to determine the genetic aspect involved in the occurrence of dental caries through a cost-effective means, which can be used in field studies.
550 kindergarten school children in the age group 3-6 years were examined during a school examination camp. Of these, only 336 children were included in the study. They were divided into four groups as follows: caries-free males (df score=0), caries-free females, caries males (df score≥10), caries females. The handprints of each child were taken and the frequency of occurrence of type of dermatoglyphic pattern on fingertip of each digit was noted. Separate df scores were recorded. SPSS software and test of proportions were used for the analysis.
Handprints of caries-free children, especially females, showed maximum ulnar loops. The caries group showed maximum occurrence of whorls (r=2:1), which were more prevalent in females on the left hand 3rd digit than in males where the whorls were found on the right hand 3 rd digit, and also low total ridge count, especially in males.
对于具有遗传基础嫌疑的病症，皮纹学可被证明是初步调查的极为有用的工具。由于龋齿是一种受遗传模式影响的多因素疾病，对高危儿童的早期预测有助于采用有效且高效的龋齿预防措施，这些措施是儿童牙医手段的一部分。
本研究旨在通过一种具有成本效益的方法确定龋齿发生所涉及的遗传方面，该方法可用于现场研究。
在一次学校检查营期间，对550名3至6岁的幼儿园儿童进行了检查。其中，只有336名儿童被纳入研究。他们被分为以下四组：无龋男性（df分数=0）、无龋女性、患龋男性（df分数≥10）、患龋女性。采集了每个孩子的手印，并记录了每个手指指尖上皮纹图案类型的出现频率。记录了单独的df分数。使用SPSS软件和比例检验进行分析。
无龋儿童，尤其是女性的手印显示出最多的尺侧箕纹。患龋组显示出最多的斗形纹（比例为2:1），在左手无名指上女性比在右手无名指上出现斗形纹的男性更普遍，并且总嵴数也低，尤其是男性。
