"ABSTRAKPada saat menyanyi, setiap penyanyi memiliki kebiasaan atau ciri tertentu, misalnyaduduk, memiringkan kepala ke satu sisi, dll yang dapat disebabkan karena rasanyaman atau karena ada gangguan. Kebiasaan atau ciri menyanyi yang disebabkanadanya gangguan dapat mengakibatkan perubahan pada postur kranioservikalsehingga terjadi hiperaktifitas otot-otot mastikasi yang dapat merupakan salah satuetiologi terjadinya gangguan sendi temporomandibula. Gangguan senditemporomandibula atau temporomandibular disorder (TMD) merupakan hal yangsering dijumpai di masyarakat. Etiologi TMD bersifat multifaktorial antara lain posturkranioservikal yang kurang baik, gangguan otot, dll. Penelitian ini bertujuanmenganalisis hubungan antara postur kranioservikal dan durasi menyanyi padapenyanyi terhadap terjadinya TMD. Desain penelitian adalah analitik observasionalcase-control terhadap 40 penyanyi yang mengalami keluhan TMD. Diagnosis TMDditegakkan dengan Research Diagnostic Criteria for Temporomandibular Disorders(RDC), sedangkan analisis postur kranioservikal digunakan radiografi sefalometriuntuk memperoleh sudut NSL/OPT. Dengani RDC, 24 penyanyi termasuk dalamkategori TMD, dan 16 penyanyi non TMD. Hasil penelitian menunjukkan tidakterdapat perbedaan postur kranioservikal antara penyanyi dengan TMD dan nonTMD dengan nilai p = 0,084. Namun terdapat hubungan yang bermakna antaradurasi menyanyi dan TMD pada penyanyi dengan nilai p = 0,000. Semakin panjangdurasi menyanyi dalam satu hari, semakin besar kemungkinan penyanyi mengalamigangguan sendi temporomandibula.

ABSTRACTWhile singing, every singer has a different style, like singing while sitting, singingwhile tilting head to one side, etc. These behaviors, whether caused by habit ordiscomfort, may change craniocervical posture, which then may trigger masticationmuscles hyperactivity. This is one possible etiology for temporomandibular disorder.Temporomandibular Disorder (TMD) is a common disorder caused by a variety offactors such as bad craniocervical posture, or muscle disorder, etc. The purpose ofthis study was to analyze the relationships among TMD, craniocervical posture, andduration of singing. This observational case-control study was done with 40 singerswith TMD symptoms. TMD was diagnosed based on Research Diagnostic Criteria forTemporomandibular Disorders (RDC). Radiographic cephalometry was taken forcraniocervical posture analysis of NSL/OPT angle. By RDC, the singers wereclassified to 24 singers with TMD and 16 singers without TMD. This study found nodifference for craniocervical posture in singers with TMD and without TMD (p =0,084). However, there was a significant relationship between duration of singingand TMD (p = 0,000). The longer the duration of singing in a day, the bigger thelikelihood to develop TMD."

"Latar Belakang: Saat ini penggantian gigi yang hilang dengan mahkota tiruan penuh dukungan implan merupakan salah satu perawatan dental yang sudah umum dilakukan. Tolak ukur keberhasilan perawatan implan gigi dapat dinilai dengan mengevaluasi performa mastikasi dan kepuasan pasien. Namun, penelitian yang mengevaluasi performa mastikasi dan kepuasan pasien dalam waktu yang singkat pada restorasi implan masih sedikit dilakukan. Tujuan penelitian ini adalah untuk mengevaluasi perubahan performa mastikasi dan kepuasan pasien dalam waktu singkat segera setelah dilakukan pemasangan mahkota tiruan penuh posterior dukungan implan. Metode: Jumlah subjek dalam penelitian ini sebanyak 50pasien dengan kehilangan posterior rahang bawah  di RSKGM FKG UI dan beberapa klinik swasta di Jakarta. Sebelum dan dua minggu setelah dilakukan pemasangan mahkota tiruan penuh dukungan implan pada gigi posterior rahang bawah,subjek dievaluasi performa mastikasinya secara objektif menggunakan color-changeable chewing gum. Selanjutnya, kepuasan responden terhadap kemampuan pengunyahan, kenyaman, dan retensi dalam mulut dievaluasi secara subjektif menggunakan VAS. Hasil: Diperoleh peningkatan secara signifikan pada performa mastikasi dua minggu setelah dilakukan pemasangan mahkota tiruan penuh posterior dukungan implan dibandingkan sebelumnya (p=0,000; p < 0,005; Wilcoxon test). Demikian pula pada kepuasan pasien ditemukan adanya peningkatan setelah dilakukan pemasangan mahkota tiruan penuh posterior dukungan implan (p=0,000; p < 0,005: Wilcoxon test). Secara statistik tidak ada pengaruh bermakna antara faktor usia dan jenis kelamin dengan  performa mastikasi (p=0,807; p=0,317; p > 0,005; Spearman Correlation test) dan kepuasaan pasien (p=0,690; p=0,317; p > 0,005; Spearman Correlation test). Kesimpulan : Terjadipeningkatan performa mastikasi dan kepuasan pasien setelah dilakukan pemasangan mahkota tiruan penuh posterior dukungan implan.

Introduction: Nowadays, dental implant can be considered as a common treatment option to do in dentistry. Succesful parameter in implant dentistr can be measured by evaluating masticatory performances and patients satisfaction. However, there has been little research on short term improvement of masticatory performances and patients satisfaction in relation to implant restoration treatment. The aim of the present study was to evaluate the improvement in masticatory performances two weeks after posterior implant restoration. Methodology: Fifty patients of the Dental Hospital Faculty of Dentistry, Universitas Indonesia and several private clinics with missing mandibular posterior tooth were included in the study. Masticatory performances were evaluated and objectively by utilizing color-changeable chewing gum and the satisfaction of the patient were evaluated by visual analog scale (VAS). Patients satisfaction regarding mastication function, comfort and retention intraoral were verified on the VAS before and two weeks after implant restoration placement. Result: Significant differences in masticatory performance were noted at baseline (before implant posterior restoration) and to two weeks after implant restoration (p=0,000; p < 0,005; Wilcoxon test). The posttreatment functional of patients satisfactions ratings significantly exceeded the VAS score (p=0,000; p < 0,005; Wilcoxon test). Statistically, theres no significant difference between age and gender correlate to mastication performance (p=0,807; p=0,317; p > 0,005; Spearman Correlation test) and patients satisfaction p=0,690; p=0,317; p > 0,005; Spearman Correlation test). Conclusion: Masticatory performances and patients satisfactions were improved two weeks after implant restoration. Age and gender did not affect the masticatory performances nor the patients satisfactions."

"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."
