The relation of bruxism and dermatoglyphics

Abstract

With the aim to examine the dermatoglyphic patterns of finger and palm, 38 bruxism patient, 18 being female were studied. Fingerprint patterns in bruxism has perviously been discussed in a few papers but this is the first paper about dermatoglyphic patterns of palm in bruxism. The purpose of this study is an attempt to find the utility of dermatoglyphics in the study of bruxism cases and to ascertain the genetic factors in the etiology of the diseases. Bruxism patients demonstrated an increase in frequency of whorls and a decrease in frequency of ulnar lops compared to that of the controls. Bruxism patients demonstrated a lower frequency of atd angle than controls. Augmentation of I loops and t triradii and diminuition of IV, H and t" triradii were observed in bruxism patients. Furthermore, the main line A ended more frequently in sector 5' in bruxism patients when compared with controls. There is no significant difference between the total finger ridge counts (TRC) and a-b ridge counts of the subjects with bruxism and that of the controls. The dermatoglyphic patterns of finger and palm was significantly different in children with bruxism. When combined with other clinical features in bruxism, dermatoglyphics can serve to strengthen a diagnostic impression.
