Relationship between Dental Archform and Dermtoglyphics

AIM: To study the associations of dermatoglyphic pattern and the dental archform among the young adult population. MATERIALS AND METHODS: The sample consisted of 150 randomly selected patients, within the age ranging from 15 to 25 years. The fingerprint patterns of the study subjects were recorded with a rolling impression technique using blue printer ink and the archform was assessed from the cast prepared from the impression of their lower dental arches. The data obtained were subjected to statistical analysis using SPSS software. The fingerprint patterns for each digit were analyzed and correlated with archform using appropriate statistical tests (chi-square test). RESULTS: Although no fingerprint pattern was found to be specific for a particular dental archform, increased frequencies of whorls in subjects with square or ovoid archform, high frequencies of ulnar loop pattern with ovoid or tapered archform, and radial loop finger ridge pattern in those with tapered archform were observed. CONCLUSION: Dermatoglyphic analysis can be used as an indicator for determining the dental archform at an early stage, thereby aiding in the orthodontic treatment of malocclusion aiming to establish favorable occlusion and long-term stability.
