Evaluation of the non-functional tooth contact in patients with temporomandibular disorders by using newly developed electronic system.

Funato M, Ono Y, Baba K, Kudo Y - J Oral Rehabil (2014)

Bottom Line: We designed and installed a software program to send emails regarding the non-functional tooth contact to the subjects' preregistered cellular phones at intervals of 20 ± 9 min daily for 10 consecutive days.Twelve patients with TMD and 12 gender- and age-matched healthy subjects responded via emails to one of 3 choices: no tooth contact, tooth contact during oral functions or tooth contact not associated with oral functions.The frequency of the non-functional tooth contact was significantly higher in the patients with TMD than in the healthy subjects (35·0% vs. 9·6%, P < 0·001), while no significant group difference was found for the frequency of functional tooth contact, the stress, anxiety, depression and personality.

Overall and daily temporal changes in the frequencies of non-functional tooth contact and functional tooth contact in the healthy subjects and the patients with TMD. Regarding daily temporal changes, no significant change was found in the frequency of non-functional tooth contact and functional tooth contact in the healthy subjects and the patients with TMD. Regarding overall temporal changes, functional tooth contact was the most frequent at 12:00 and 19:00 (arrows) in both the groups.

fig02: Overall and daily temporal changes in the frequencies of non-functional tooth contact and functional tooth contact in the healthy subjects and the patients with TMD. Regarding daily temporal changes, no significant change was found in the frequency of non-functional tooth contact and functional tooth contact in the healthy subjects and the patients with TMD. Regarding overall temporal changes, functional tooth contact was the most frequent at 12:00 and 19:00 (arrows) in both the groups.

Mentions: Regarding daily temporal changes in the non-functional tooth contact or functional contact, no significant change was found in both groups (P > 0·05). Functional tooth contact was the most frequent at 12:00 and 19:00 in both groups (Fig.2).
