The aim of the study was to investigate the effect of bruxism on Temporomanbular joint functionality and dysfunction severity in individuals with Temporomandibular Dysfunction (TMD).
The study included 91 individuals aged 20-55 years with TMD. Participants who volunteered to participate in the study signed the Informed Consent Form and completed the Descriptive Data Form including demographic characteristics. The presence of bruxism in individuals with TMD was questioned and the maximum mouth opening measurement was recorded. TMD severity was assessed by Fonseca's Anamnestic Questionnaire (FAQ), pain severity was assessed by Numeric Pain Scale (NPS), and masticatory and TMJ functioning was assessed by JAW Functional Limitation Scale-20 (JFLS-20). The evaluations of the participants were performed only once.
Study Type
OBSERVATIONAL
Enrollment
91
The questionnaire includes 10 questions about joint, head and neck pain, pain during masticatory activity, parafunctional habits, decreased joint motion, impaired occlusion and emotional stress.
It is a simple, reliable and short-term method that is frequently used to measure pain intensity in the clinic.
It includes a total of 20 items, with "0" indicating no limitation and "10" indicating severe limitation in each item, about the function of the TMJ during different activities, difficulty in chewing and jaw limitation.

Bruxism evaluation
Sleep bruxism reported by the individual was recorded. As clinical diagnostic criteria for bruxism; the presence of regular or frequent teeth clenching and grinding sounds followed by pain or fatigue in the jaw muscles on waking up in the morning, temporal headache, masseter muscle hypertrophy, abnormal tooth abrasion and/or jaw locking were questioned and the presence of one or more clinical findings was recorded as bruxism.
Time frame: April 2023- September 2023
Maximum mouth opening
Maximum pain-free mouth opening was measured with a 15 cm ruler
Time frame: April 2023- September 2023
Severity of Temporomandibular dysfunction
Fonseca's Anamnestic Questionnaire (FAQ) was used. The questionnaire includes 10 questions about joint, head and neck pain, pain during masticatory activity, parafunctional habits, decreased joint motion, impaired occlusion and emotional stress. As a result of the questionnaire, the presence of TMD is accepted in patients with a score of 25 and above, and the severity can be classified as mild TMJ disorder (25-45), moderate TMJ disorder (50-65) and severe TMJ disorder (70-100).
Time frame: April 2023- September 2023
Pain intensity
Numeric Pain Scale (NAS): It is a simple, reliable and short-term method commonly used in the clinic to measure pain intensity. The patient is told that the most severe pain he/she feels in the TMJ region is 10, and if there is no pain, the pain intensity is 0. The participant was asked to say a number between 0 and 10 corresponding to the intensity of pain felt in the TMJ region.
Time frame: April 2023- September 2023
Jaw Functionality
Jaw Functionality Limitation Scale-20 was used. It includes a total of 20 items, with "0" indicating no limitation and "10" indicating severe limitation in each item, about the function of the TMJ during different activities, difficulty in chewing and jaw limitation. As a result of the questionnaire, it was reported that TMJ function was limited in individuals with a score of 5 and above.
