Study summary

comparing the effects of Laser therapy with anterior re-positioning splint and a placebo group on clinical signs and symptoms of temporo-mandibular dis-function and assessing articular disc morphology and configuration with magnetic resonance imaging.

Read the detailed description

to compare the clinical effects of Laser therapy as assessed with research diagnostic criteria of temporo-mandibular disorders to a group that received anterior re-positioning splint therapy and a control group that received placebo Laser. Diagnosis for disc displacement with reduction was performed with magnetic resonance imaging before treatment. assessment of the clinical and MRI findings was again performed after a 3 months observation period.

What researchers measure

Primary outcomes

  1. Level of temporomandibular joint pain: assessed by using subjective visual analogue scale

    current level of temporomandibular joint pain assessed by using subjective visual analogue scale from 1 to 10 according to the research diagnostic criteria of temporomandibular disorders diagnostic sheets, zero indicates no pain, while 10 indicates the worst pain

    Time frame: 3 months

Secondary outcomes

  1. click: joint sound

    joint sound., it is a binary measurement assessed by hand palpation

    Time frame: 3 months

  2. limitation of mandibular movements

    mouth opening, measured between the incisal edges of upper and lower incisors using a digital caliper, right and left mandibular movements, measured from upper dental midline to lower dental midline using a digital caliper.

    Time frame: 3 months

  3. disc recapture

    change in articular disc morphology and configuration using two dimensional measurements on a DICOM viewer software including both linear and angular measurements in relation to cartesian coordinates X and Y

    Time frame: 3 months
