| Deep friction massage | Other | Submitted to three session weekly 30-minute sessions of therapy will performed by the administration of sliding and kneading maneuvers of the masseter and temporalis muscles, bilaterally,lateral pterygoid and digastric over four consecutive weeks (total:12 sessions) Sliding consisted of a unidirectional movement in which part of the therapist's hand (mainly the fingertips) will used, moving from the proximal to the distal portion of the face with constant, progressive pressure compatible with the status of each tissue. The degree of pressure varied depending on the level of pain, sensitivity and tension in each individual. Kneading consisted of a gripping maneuver of a muscle group or portion of a muscle.Then follow-up with a passive stretch to the muscle. This will repeated for three to five times for three sessions per week for 4 weeks. |

| changes of Trigger point pressure pain threshold | To compare pressure pain threshold (PPT) values for selected muscles (temporalis, masseter, digastric and lateral pterygoid) in patients with bruxism before and after treatment using Pressure Algometer. | Pre- and post-treatment (twelve treatment sessions within one month, three sessions per week). |
| Changes of mandibular range of motion at month of treatment | Vernier caliper used to measure opening, lateral movements, protraction and retraction. | Pre- and post-treatment (twelve treatment sessions within one month, three sessions per week). |
| Measure | Description | Time Frame |
|---|---|---|
| Changes of proprioception awareness | Measure ability of patient before treatment and after to move mandible to specific angle(measured by vernier caliper) identified before test | Pre- and post-treatment (twelve treatment sessions within one month, three sessions per week). |

| Pressure release | Other | First, using a pincer grasp moved throughout the fibers of the pterygoid, masseter, digastric and temporalis muscles to palpate the muscle aiming to locate a trigger point . A common location is detected according to Simon and Travell book. Once located on the trigger point, apply an IC by gradually applying pressure to the trigger point with your thumb. Keep in communication with the patient, checking to ensure that in staying within the limits of his pain tolerance. Hold this technique for approximately 20 seconds to 1 minute, patient tells you that pain has diminished, or until feels the muscle fibers begin to relax under your pressure. Once feel this release, gradually release pressure. All identified trigger points were treated. Then follow-up with a passive stretch to the muscle. This will repeated for three to five times for three sessions per week for 4 weeks. |

Using Perceived Stress Scale to measure stress which consist of 10 items. The 10 items in the scale inquire about feelings and thoughts that tap the degree to which respondents find their current life situation unpredictable, uncontrollable and stressful. Respondents indicate how often in the past month they have felt or thought a certain way on a 5-point Likert scale (0 = never, 1 = almost never, 2 = sometimes, 3 = fairly often, 4 = very often). The higher the score the higher the perceived stress is. The scale correlates with different psychosocial measures specifically depression, anxiety, and perception of poor health as well as with decreased satisfaction with self, job and life in general. |
| Pre- and post-treatment (twelve treatment sessions within one month, three sessions per week). |
| Anxiety | Measured using the State-triat Anxiety Inventory. It consists of two independent scales, with 20 questions each, measuring anxiety as a trait (in general) and as a state (at the moment). Each question is scored (from 1 to 4), and scores for the scales range from 20 to 80 as follows: mild anxiety (20 to 34); moderate anxiety (35 to 49); high anxiety (50 to 64); and very high anxiety (65 to 80). | Pre- and post-treatment (twelve treatment sessions within one month, three sessions per week). |
| Changes of quality of sleep at month of treatment | Using The Pittsburgh Sleep Quality Index, It consists of 19 questions grouped under seven domains: subjective sleep quality; sleep latency; sleep duration; usual sleep efficiency; sleep disturbances; use of medications; and diurnal dysfunction. Each domain is scored (0 to 3) and a total score (0 to 21) is calculated as follows: scores ranging from 0 to 4 are indicative of good sleep quality; scores from 5 to 10 suggest poor sleep quality; scores above 10 are suggestive of sleep disorders. Five other questions are answered by participants' spouses or partners, and further characterize sleep quality. | Pre- and post-treatment (twelve treatment sessions within one month, three sessions per week). |
| Temporomandibular (TMJ) function | Using Temporomandibular Disorder (TMD) Disability Index Questionnaire,The TMD Disability Index consists of ten questions regarding disability associated with TMD, and each question is scored from 0-4. Higher scores represent greater levels of disability. | Pre- and post-treatment (twelve treatment sessions within one month, three sessions per week). |
| Changes in Oral Health Impact Profile. | using Oral Health Impact Profile.(OHIP), The OHIP-14 is a 14-items questionnaire designed to measure self-reported functional limitation that focuses on seven dimensions of impact (functional limitation, pain, psychological discomfort, physical disability, psychological disability, social disability and handicap) with participants being asked to respond according to frequency of impact on a 5-point Likert scale coded never (score 0), hardly ever (score 1), occasionally (score 2), fairly often (score 3) and very often (score 4) using a twelve-months recall period. | Pre- and post-treatment (twelve treatment sessions within one month, three sessions per week). |
