Joint sound is one of the signs of the temporomandibular joint disorder dan its characteristics are tought to be able to establish the gravity of the disorder. The aim of this study was to analyze the relation between the sound characteristics - its pitch and intensity - and the gravity of the temporomandibular joint disorder. The subjects of this research were 54 students who fulfilled the criteria included in the basic questionnaire which was distributed among all the 4th and 6th semester dental students of Faculty of Dentistry University of Indonesia. The gravity of the disorder was obtained from the subjective as well as the objective examination, using Helkimo index. 108 joint sound samples of the left and right joint were recorded during opening and closing movement of the mandible, using a modified stethoscope which was connected to a personal computer. The analysis of the joint sound characteristics was done with audio analysis software Cool Edit 2000. A one wat anova test showed a significant relation between the gravity of temporomandibular joint disorder and the intensity of the joint sound (p<0.05). The gravity of the disorder was equivalent to the intensity of the sound, however there was no significant relation between the joint sound pitch and the gravity of the temporomandibular joint disorder. It was concluded that the joint sound intensity was worthy of further study as a sign of diagnostic value.

Latar belakang: Sleep bruxism merupakan aktivitas oromandibular stereotip sewaktu tidur yang ditandai oleh grinding dan clenching gigi. Penderita sleep bruxism umumnya identik dengan adanya nyeri temporomandibular disorder (TMD). Metode: Penelitian potong lintang ini menggunakan 97 subjek terdiri dari 38 orang laki-laki dan 59 orang perempuan, dengan rentang usia 17-55 tahun. Penilaian sleep bruxism dilakukan menggunakan kuesioner oleh American Academy of Sleep Medicine versi Bahasa Indonesia, serta penilaian TMD dilakukan menggunakan indeks diagnostik DC/TMD. Hasil: Terdapat hubungan yang signifikan secara statistik antara sleep bruxism dan TMD. Sleep bruxism, jenis kelamin dan stress emosional menjadi faktor prediktor terhadap TMD. Pada analisis multivariat dengan regresi logistik diketahui bahwa jenis kelamin dan stress emosional berpengaruh terhadap TMD dengan odds ratio (OR) masing-masing sebesar 3,113 dan 4,043, sedangkan sleep bruxism tidak memiliki pengaruh yang signifikan terhadap TMD dengan OR sebesar 1,141. Kesimpulan: Sleep bruxism berhubungan dengan TMD, namun memiliki pengaruh yang lebih kecil dibandingkan dengan jenis kelamin dan stress emosional. ......Background: Sleep bruxism is a stereotypical oromandibular activity during sleep characterized by grinding and clenching of teeth. Patients with sleep bruxism are generally associated with temporomandibular disorder (TMD) pain. Methods: This cross-sectional study used 97 subjects consisting of 38 male and 59 female, with an age range of 17-55 years. The assessment of sleep bruxism was carried out using Indonesian version of the questionnaire based on the American Academy of Sleep Medicine sleep bruxism questionnaire, and the TMD assessment was carried out using the DC/TMD diagnostic index. Results: There was a statistically significant relationship between sleep bruxism and TMD. Sleep bruxism, gender and emotional stress are predictors of TMD. In multivariate analysis with logistic regression, it was found that gender and emotional stress had an impact on TMD with odds ratio (OR) of 3.113 and 4.043, respectively, while sleep bruxism had no significant impact on TMD with an OR of 1.141. Conclusion: Sleep bruxism is associated with TMD, but has a smaller impact compared to gender and emotional stress.

Latar Belakang: Etiologi temporomandibular disorder (TMD) adalah multifaktor, salah satunya adalah kebiasaan parafungsi yaitu sleep bruxism. Pasien sleep bruxism sering mengalami tanda dan gejala TMD yaitu nyeri dan keterbatasan pembukaan mulut. Oleh karena itu evaluasi deteksi lebar pembukaan mulut digunakan rutin untuk pemeriksaan sendi temporomandibula, namun hubungan sleep bruxism dengan lebar pembukaan mulut ini masih kurang jelas. Tujuan: Menganalisis reliabilitas dan validitas kuesioner sleep bruxism dan menganalisis apakah terdapat hubungan antara sleep bruxism dengan lebar pembukaan mulut. Metode: Desain potong lintang. Kuesioner sleep bruxism dievaluasi menggunakan internal consistency reability test dan metode test-retest (ICC value), sedangkan validitas diukur dengan validasi konvergen, dan untuk hubungan antara sleep bruxism dengan lebar pembukaan mulut dilakukan dengan analisa bivariat. Hasil: Nilai Cronbach's alpha 0.515 menunjukkan konsistensi internal yang cukup baik, dan nilai ICC test-retest > 0.808 sehingga disimpulkan kuesioner adalah reliabel, sedangkan hasil uji validitas dengan uji korelasi koefisien kontingensi adalah berbeda bermakna (p<0.05) dengan nilai korelasi lemah 0.362. Dengan demikian, alat ukur kuesioner sleep bruxism versi Bahasa Indonesia reliabel dan valid. Untuk lebar pembukaan mulut maximum comfortable, tidak ditemukan perbedaan bermakna antara pasien sleep bruxism dengan non sleep bruxism, dan antara pasien sleep bruxism TMD dengan sleep bruxism non TMD (p>0.05), sedangkan lebar pembukaan mulut maximum assisted pada pasien sleep bruxism TMD dan sleep bruxism non TMD terdapat perbedaan bermakna (p<0.05). Berdasarkan jenis kelamin, lebar pembukaan mulut maximum comfortable antara pria dan wanita berbeda bermakna (p<0.05). Kesimpulan: Kuesioner sleep bruxism dalam bahasa Indonesia reliabel dan valid sehingga dapat digunakan di Indonesia. Tidak terdapat hubungan antara sleep bruxism dengan lebar pembukaan mulut. ...... Background: The etiology of temporomandibular disorders (TMD) is multifactor, one of them is parafunctional habit, such as sleep bruxism. Patients with sleep bruxism are more likely to experience jaw pain and limitation of jaw movement, than people who do not. Limitation of mouth opening is one of the cardinal signs found in TMD. Therefore, evaluation of maximum mouth opening is used as part of routine function assessment of temporomandibular joint, but the relationship between sleep bruxism and mouth opening is still unclear. Objective: To analyze the reliability and validity of sleep bruxism questionnaire in Indonesia and also to analyze the relationship between sleep bruxism and mouth opening. Methodolgy: Cross-sectional design. Sleep bruxism questionnaire was evaluated using internal consistency reability test and test-retest methods (ICC value), while the validity was analyzed by convergent validity. The relationship between sleep bruxism and mouth opening was analyzed with bivariate analysis. Results: Cronbach's alpha showed moderate result (0.515), and ICC test-retest value was above 0.808, meaning the questionnaire was reliable. Validity analysis using coefficient contingency correlation showed significantly different (p<0.05) and weak correlation value (0.362). Thus, the Indonesian version of sleep bruxism questionnaire was reliable and valid. Relationship between maximum comfortable mouth opening on sleep bruxism and non bruxism, and between sleep bruxism non TMD and sleep bruxism with TMD were not significantly different (p>0.05), but relationship between assisted mouth opening on sleep bruxism non TMD and sleep bruxism with TMD were significantly different (p<0.05). Based on gender, maximum comfortable mouth opening were significantly different between sleep bruxism non TMD and sleep bruxism with TMD (p<0.05). Conclusion: The Indonesian version of sleep bruxism questionnaire is reliable and valid, and there is no relationship between sleep bruxism and maximum mouth opening.

Tujuan: Tujuan dari kajian sistematis ini adalah untuk mengidentifikasi alat ukur yang dapat mengevaluasi disfungsi otot orofasial saat mastiksai dan/atau deglutasi pada pasien Temporomandibular Disorders (TMD).  Metode: Protokol kajian disusun dan diregistrasikan pada International Prospective Register of Systematic Reviews. Pencarian literatur dilakukan pada enam basis data daring yaitu Pubmed, Scopus, EBSCO, ProQuest, SpringerLink and Wiley dengan membatasi hanya literatur dalam bahasa Inggris dan dipublikasikan dalam rentang waktu tahun 2012 hingga 2022. Kriteria inklusi yang ditetapkan adalah studi yang mengevaluasi otot orofasial dalam pemeriksaan perilaku, performa, efisiensi, durasi, frekuensi mastikasi dan/atau deglutasi pada pasien TMD. Studi yang terpilih sesuai kriteria inklusi dilakukan ekstraksi data dan penilaian risiko bias menggunakan borang Joanna Briggs Institute Critical Appraisal Checklist. Hasil: Dari proses seleksi didapatkan 2848 literatur dan terdapat 21 literatur yang termasuk dalam kriteria inklusi. Untuk mengukur disfungsi otot orofasial, empat belas literatur menggunakan alat ukut surface electromyography (sEMG), dua belas literatur menggunakan Orofacial Myofunctional Evaluation with Scores (OMES) dan satu literatur menggunakan MBGR Protocol. OMES and MBGR merupakan protokol pemeriksaan yang mencakup postur, mobilitas dan fungsi otot orofasial dari persepsi operator.  Kesimpulan: Meskipun sifatnya yang non invasif, perolehan data sEMG saja tidak cukup untuk mendapatkan informasi disfungsi otot orofasial saat mastikasi dan deglutasi. OMES dan MBGR memberikan data tambahan yang luas dalam aspek postur, mobilitas dan fungsi dari otot orofasial. Keduanya dapat diaplikasikan secara efisien dalam mengidentifikasi serta mengevaluasi perawatan pada pasien TMD.  ......Objectives: The aim of this systematic review was to identify instruments that evaluates orofacial muscle dysfunctions during mastication and/or deglutition in temporomandibular disorders  Materials and methods: Protocol was organized and registered to the International Prospective Register of Systematic Reviews. Literature search were conducted in 6 databases, Pubmed, Scopus, EBSCO, ProQuest, SpringerLink and Wiley with restriction for studies that are published in English between 2012-2022. The inclusion criteria are studies evaluating orofacial muscle within behaviour, performance, efficiency, duration, frequency assesment during mastication and/or deglutition in TMD patients. Data extraction were followed by risk of bias (RoB) assessment using the Joanna Briggs Institute Critical Appraisal Checklist and continued with further analysis.  Results: Through selection process on 2848 articles found, 21 were included. For measurement on orofacial muscle, fourteen studies used surface electromyography (sEMG), twelve studies used Orofacial Myofunctional Evaluation with Scores (OMES) and one study used MBGR Protocol. OMES and MBGR are examination protocols that covers posture, mobility and functions from the perception of operator.   Conclusions: Despite that it is non invasive, sEMG data are not sufficient to obtain information on muscle dysfunction during mastication and deglutition. OMES and MBGR protocols provides broad supplementary data on posture, mobility and functions of orofacial muscle. Both protocols are efficiently applicable for identification and treatment evaluation for TMD patients.
