The relation of bruxism and dermatoglyphics.

With the aim to examine the dermatoglyphic patterns of finger and palm, 38 bruxism patients, 18 being female were studied. Fingerprint patterns in bruxism has previously been discussed in a few papers, but this is the first paper about dermatoglyphic patterns of palm in bruxism. The aim of this study of finger and palm prints in patients with bruxism were to discuss the importance of dermatoglyphic patterns in the diagnosis and etiology of the disease. Bruxism patients demonstrated an increase in frequency of whorls and a decrease in frequency of ulnar loops than the controls. Patients with bruxism demonstrated a lower frequency of atd angle than controls. Augmentation of I loops and t triradii and diminution 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 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.
