Dermatoglyphics refers to study of the intricate dermal ridge configurations on the skin covering the palmar and plantar surfaces of hand and feet. The basis of considering dermatoglyphic patterns as genetic marker for dental caries is that the epithelium of finger buds as well as enamel has ectodermal origin, and both develop at the same time of intrauterine life.
To assess the relationship between fingerprint patterns and dental caries among preschool children of Lucknow city.
This study was of cross-sectional design.
The study group comprised 512 preschool children 2-6 years of age. The prevalence of caries was recorded using "Dentition status and treatment needs" (WHO basic oral health assessment form, 1997). They were divided into three groups as follows: Group I (dmft score = 0-2), group II (dmft score = 3-4) and group III (dmft score ≥5). The handprints of each child were taken using a stamp pad. The fingertip patterns were analyzed according to the classical method and were classified according to the topological method. The frequency of occurrence of type of dermatoglyphic pattern on fingertip of each digit was noted.
Chi-square test was used to test the significant difference in proportions. Means were compared using Student's t-test and analysis of variance (ANOVA) or F-test.
Subjects belonging to groups II and III showed maximum occurrence of whorl pattern on all digits. Group I subjects had maximum occurrence of arch pattern. All the variables had statistically significant value, with a degree of divergence of specific dermatoglyphic patterns among all three groups.
The dental caries susceptibility of an individual increased with incidence of whorl pattern and it decreased with incidence of arch pattern.

皮纹学是指对覆盖在手和脚的手掌及足底表面皮肤上复杂的皮嵴形态的研究。将皮纹模式视为龋齿遗传标记的依据是，指芽的上皮组织和牙釉质都起源于外胚层，且二者在子宫内生活的同一时期发育。
评估勒克瑙市学龄前儿童指纹模式与龋齿之间的关系。
本研究为横断面设计。
研究组包括512名2至6岁的学龄前儿童。使用“牙列状况与治疗需求”（世界卫生组织基本口腔健康评估表，1997年）记录龋齿患病率。他们被分为以下三组：第一组（dmft评分=0 - 2），第二组（dmft评分=3 - 4）和第三组（dmft评分≥5）。使用印台采集每个儿童的手印。根据经典方法分析指尖模式，并根据拓扑方法进行分类。记录每个手指指尖上皮纹模式类型的出现频率。
采用卡方检验来检验比例的显著差异。使用学生t检验、方差分析（ANOVA）或F检验比较均值。
第二组和第三组的受试者在所有手指上涡纹模式出现的频率最高。第一组受试者弓形模式出现的频率最高。所有变量均具有统计学意义，三组之间特定皮纹模式存在一定程度的差异。
个体的龋齿易感性随涡纹模式发生率的增加而增加，随弓形模式发生率的降低而降低。如何引用本文：Singh E, Saha S, Jagannath GV, Singh S, Saha S, Garg N. 印度勒克瑙市学龄前儿童皮纹特征与龋齿的关联。《国际临床儿科牙科学杂志》2016；9(1):39 - 44。
