"Pola grinding oklusal selama sleep bruxism dan kelainan temporomandibular. Sleep Bruxism merupakan salah satu etiologi terjadinya temporomandibular disorder (TMD), dan menyebabkan banyak kelainan di rongga mulut seperti keausan gigi atau faset. Namun, hingga kini belum ada penelitian tentang hubungan antara sleep bruxism dan TMD. Tujuan: Untuk mengetahui apakah ada hubungan antara pola grinding oklusal selama sleep bruxism dan kelainan temporomandibular. Metode: Penelitian cross-sectional dilakukan melibatkan 30 pasien yang diduga mengalami sleep bruxism yang datang ke Rumah Sakit Pendidikan Fakultas Kedokteran Gigi Universitas Indonesia (FKG UI RSGMP). Mereka mengisi 2 kuesioner, yaitu kuesioener berisi indeks ID-TMD dan kuesioner dari American Academy of Sleep Medicine. BruxChecker dibuat sesuai untuk masing-masing pasien, kemudian digunakan selama dua malam untuk merekam pola grinding oklusal. Pola grinding oklusal dikategorikan menjadi sisi laterotrusive grinding (LG) dan sisi mediotrusive. Selanjutnya, LG dibagi menjadi tiga klasifikasi: gigi insisif-kaninus (IC), gigi insisif-kaninus-premolar (ICP) dan gigi insisif-kaninus-premolar-molar (ICPM). Sisi Mediotrusive diklasifikasikan sebagai kontak mediotrusive (MC) dan mediotrusive grinding (MG). Hasil: Ditemukan bahwa pola grinding oklusal pada subjek tidak TMD adalah IC + MC, subjek dengan TMD ringan adalah ICP + MG, dan subjek dengan TMD moderat adalah ICP + MG dan ICPM + MG. Pola grinding ICP dan ICPM mempengaruhi TMJ lebih signifikan dibandingkan dengan pola grinding IC. Simpulan: Terdapat hubungan yang bermakna antara pola grinding oklusal selama sleep bruxism dan TMD.

Sleep Bruxism is a significant etiology of temporomandibular disorder (TMD) and causes many dental or oral problems such as tooth wear or facet. There is no study analyzing the relationship between sleep bruxism and TMD. Objective: To investigate any relationship between occlusal grinding pattern during sleep bruxism and temporomandibular disorder. Methods: A cross-sectional study involving 30 sleep bruxism patients attended the Faculty Dentistry Universitas Indonesia Teaching Hospital (RSGMP FKG UI). Completion of 2 forms of ID-TMD index and questionnaire from American Academy of Sleep Medicine were done. BruxChecker was fabricated and used for two nights to record the occlusal grinding pattern. The occlusal grinding pattern was categorized into laterotrusive grinding (LG) and mediotrusive side. Further divisons of LG were: incisor-canine (IC), incisor-caninepremolar(ICP) and incisor-canine-premolar-molar (ICPM). Mediotrusive side was classified as mediotrusive contact (MC) and mediotrusive grinding (MG). Results: It was found that occlusal grinding pattern in non-TMD subjects were IC+MC, in subjects with mild TMD were ICP+MG and in subjects with moderate TMD were ICP+MG and ICPM+MG. TMJ was more significantly affected by ICP and ICPM grinding pattern than that of IC. Conclusion: There was a significant relationship between occlusal grinding pattern during sleep bruxism and TMD."

"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."

"Every dentist knows about bruxism, however, the etiology. the treatment, and the relationship between bruxism and temporomandibular disorders (TMD) are still unknown and controversial. Bruxism can happen to all ages, from children (15% of all children) to adults (96% of all adults), male and female. Given the data, what can a dentist do to help the patient with bruxism? The various clinical signs that can be found in these patients are excessive tooth wear, muscle and joint fatigue, headache, tooth sensitivity or mobility, fractures of teeth and restorations, as well as TMD symptoms. Currently no method can permanently eliminate bruxism, but there are several ways to help patients with symptoms caused by parafunctions. Two categories of bruxism are bruxism without symptoms and bruxism with symptoms that lead to temporomandibular disorders. To make the patient aware of the destructive parafunctional activities, self-monitoring, biofeedback, medications, occlusaladjustment and fabricating a splint can reduce the unfavorable consequences of bruxism, although they usually do not stop it. Periodical control is advisable."

"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."
