Dental caries is the disease of the calcified tissues of the teeth resulting from the action of microorganisms on carbohydrates characterized by a decalcification of inorganic portion of the tooth and accomplished or followed by disintegration of organic portion. Genetic susceptibility to dental caries is dependent on certain factors, which, if evaluated, can help in estimating disease situation prematurely. Dermatoglyphics are the genetically determined dermal ridge configurations on the digits, palms and soles, influenced by environmental forces that are operating before birth. Hence, the study was undertaken to establish a possible link between dental caries and dermatoglyphics and to determine whether specific dermatoglyphic patterns exist which help in predicting the occurrence of dental caries.
The dermatoglyphics of 50 caries free (CF) and 50 individuals with dental caries (WDC) were taken and compared with the microbial levels of and lactobacilli, and results were evaluated qualitatively and quantitatively.
Analysis was done using value, Chi-square test and Student's -test.
(1) Whorl pattern was more common in individuals WDC ( < 0.0001) as compared to the CF individuals who exhibited more loop pattern ( = 0.002). (2) Whorl pattern had significant association with the microbial counts of ( = 0.383) and ( = 0.015) with no such statistically significant correlation with loop pattern in the disease group. (3) ≤6 loops was a good predictor of caries. ≥4 whorls was a moderate predictor of caries.
龋齿是牙齿钙化组织的疾病,由微生物对碳水化合物的作用引起,其特征是牙齿无机部分脱钙,并伴有或随后发生有机部分的分解。龋齿的遗传易感性取决于某些因素,如果对这些因素进行评估,有助于过早估计疾病情况。皮纹是手指、手掌和脚底由遗传决定的皮嵴形态,受出生前起作用的环境因素影响。因此,本研究旨在建立龋齿与皮纹之间的可能联系,并确定是否存在有助于预测龋齿发生的特定皮纹模式。
采集50名无龋(CF)个体和50名有龋(WDC)个体的皮纹,并与变形链球菌和乳酸杆菌的微生物水平进行比较,对结果进行定性和定量评估。
采用t值、卡方检验和学生t检验进行分析。
(1)与表现出更多箕形纹(P = 0.002)的CF个体相比,涡形纹在WDC个体中更常见(P < 0.oooo1)。(2)涡形纹与变形链球菌(P = 0.383)和乳酸杆菌(P = 0.015)的微生物计数有显著相关性,在疾病组中与箕形纹无统计学显著相关性。(3)≤6条箕形纹是龋齿的良好预测指标。≥4条涡形纹是龋齿的中度预测指标。
