It has been suggested that the length of time from the onset of symptoms to the time the patients seek treatment and sleep disorders has a large effect on the treatment of TMD, especially in conservative treatment. In this experiment the relationship between the time it took patients to seek treatment and bruxism and sleep disorders was clarified. Twenty female TMD patients (13 arthrogenous, 7 myogenous) in their twenties were selected. The length of time it took for the patients to seek for treatment was determined from the questionnaire. Using a wireless telemeter system, the EEG, FOG, ECG, masseter EMG, mental EMG, and respirogram of subjects were recorded throughout night and the frequency of bruxism and sleep apnoea was calculated. Bruxism was defined as those burst groups associated with muscular activities that lasted more than 5 s or had more than two bursts within 5 s. The relationship among the length of time needed to seek for treatment, frequency of bruxism and sleep apnoea was investigated. Both the frequency of bruxism and sleep apnoea increased when the length of time it took for the patient to seek treatment was long (bruxism: r =0·650, apnoea: r =0·655, P < 0·01). The frequency of sleep apnoea increased as the frequency of bruxism increased ( r =0·495, P < 0·05). From these results it was suggested that there was a direct correlation among the three factors, the length of time it took to seek for treatment, frequency of bruxism and frequency of sleep apnoea. and when taking natural history it was imperative to pay more attention.
