Children and their parents were trained about bruxism, parafunctional oral habits, and sleep hygiene education. Therapeutic exercises about head-neck posture, breathing, and relaxation were given for 8 weeks.

82 children were evaluated. Among those, 37 volunteered children were trained and demonstrated in practice about bruxism, parafunctional oral habits, sleep hygiene education, and 5x5 therapeutic exercises. Therapeutic exercises program 5x5 included breathing exercises, head-neck, and scapular posture exercises which included jaw muscle and neck muscle stretching and strengthening exercises. They were asked to repeat each exercise with 5 set and 5 times a day for 8 weeks.

Sleep hygiene education was given to parents and children with explanation of the parafunctional oral habits to raise awareness about being conscious about the oral habits. Sleep hygiene education includes routines about bedtime, sleeping room environment, and timing for exercise.

The pain was measured with the Visual Analogue Scale (VAS) and the degree of pain was questioned in various situations. The children were told to mark the value of 0 when they felt no pain, 10 when they felt excruciating pain, and to mark the pain they felt within this range. And it was supported by facial expressions.

Headache when waking up in the morning, jaw pain when waking up in the morning, jaw pain while eating, jaw pain after meals, and jaw pain before going to bed at night were questioned and each was measured by VAS.

Children's Sleep Habits Questionnaire (CSHQ) investigate children's sleep habits and sleep-related problems, and its Turkish validity and reliability were used. After giving the necessary information about the questionnaire to the parents, they were asked to fill it out.

The CSHQ has satisfactory psychometric properties in children and has been used in the investigation of sleep in children. The form consists of 33 items in total. There are eight subscales in the scale, which can be listed as bedtime resistance, delayed falling asleep, sleep duration, sleep anxiety, night awakenings, parasomnias, impaired breathing during sleep, and daytime sleepiness.

A person's overall score can range from 0 to 84. A low overall score indicates positive oral habit, while a higher score indicates negative oral habit.

After making sure that the questions were correctly understood by the children, the markings of the answers were made by the practitioner.

TMJ ROM was analyzed as active and passive. Maximal mouth opening and right-left shifts were measured using a linear ruler. Active and passive maximal mouth opening, right and left lateral displacement, and protrusion of the TMJ were measured in millimeters (mm) based on reference points in the maxillary and mandibular anterior incisors.

Crepitation and joint clicking sounds were questioned during mouth opening and closing, and normal line deviations were detected during mouth opening.
