An Follow-up Study of Occlusal Adjustment for Orofacial Pain

Status Recruiting

Clinical Trial Summary

The purpose of this study is to determine whether what kind of occlusion are related the orofacial pain under investigation, and whether occlusal adjustment have an effect in relief of this kind of orofacial pain.

Clinical Trial Description

1. T-scan analysis system is used to record the occlusal contact relationships. And at same time, Electromyographic recording system is used to record the Masseter (MM) and Anterior Temporalis (TA) muscles' surface electromyographic (SEMG) in the two time points: before the treatment and 4-weeks follow-up after treatment. After recording, several parameters is taken to indicate the occlusal changes when researchers set the T-Scan occlusal parameters as 100% intercuspal position (ICP) maximum voluntary clenching (MVC), 75% ICP-MVC, 50% ICP-MVC, 25% ICP-MVC, and the number of occlusal contact and the values of the the Masseter (MM) and Anterior Temporalis (TA) muscles' surface electromyographic (SEMG) values is acquired by the software in the screen. 2. Occlusal imprints which indicates the their occlusal relationships is made by researchers when the volunteers ICP clenching in the two time points: before the treatment and 4-weeks follow-up after treatment. Break-over and the sub-break-over point of the occlusal imprints is amplified by software. The investigators compute the number and area about that. 3. The investigators also recorded frequency of attack and score of visual analogue scale (VAS), the dosage of drug, and short form-McGill-2 in the follow-ups time frame: immediately after the first treatment, 1-, 4-, 12- and 24-weeks after treatment. ;
