"Bruxism adalah serangkaian aktifitas kontraksi otot rahang saat tidur yang bersifat ritmik, singkat, dan kuat, terjadi pada posisi sentris maupun eksentris rahang. Bruxism merupakan salah satu etiologi gangguan sendi temporomandibula (STM), namun bagaimana mekanisme dan hubungannya dengan gejala gangguan STM masih menjadi kontroversi dan belum jelas. Tujuan dari penelitian cross sectional ini adalah untuk mencari hubungan antara bruxism dan nyeri atau kaku STM pada mahasiswa preklinik FKGUI tahun 2007. Penelitian dilakukan di FKGUI, dimulai dari akhir November sampai minggu pertama Desember 2007, melibatkan 128 subyek penelitian yang dipilih berdasarkan random sampling. Subyek diminta menjawab 3 kuesioner yang diadaptasi dari RDC (Research Diagnostic Index), Diagnostic Index dan Oral Parafunction dan data kemudian dianalisa enggunakan uji Fisher.Hasil penelitian menunjukkan prevalensi bruxism sebesar 15.6%, yang mengalami nyeri atau kaku STM 8.6%, yang sering mengalami kaku sesaat di sekitar STM pada pagi hari saat bangun tidur 3.1%, dan yang jarang 22.7%. Untuk bruxism dan gejala nyeri atau kaku STM, hasil analisis menunjukkan nilai p=0.376 (p>0.05) dengan demikian dapat disimpulkan tidak ada hubungan antara bruxism dan nyeri STM. Hasil analisis hubungan antara bruxism dan kaku sesaat di sekitar STM pada pagi hari saat bangun tidur menunjukkan nilai p=0.498 (p>0.05), sehingga dapat disimpulkan tidak ada hubungan antara bruxism dan kaku sesaat di sekitar STM pada pagi hari saat bangun tidur. Sebagai kesimpulan, dapat dikatakan bahwa tidak ada hubungan antara bruxism dan nyeri atau kaku STM pada mahasiswa preklinik FKGUI tahun 2007.

Bruxism is a sleep-associated series of rhythmic, brief, strong contractions of the jaw muscles occurring in either centric or eccentric jaw position. Bruxism is one of the etiologies of temporomandibular disorder (TMD), but the mechanism and its relationship with TMD symptoms are still controversial and unclear. The purpose of this cross sectional observation is to describe the relationship between bruxism and pain stiffness of TMJ in preclinical dental students of University of Indonesia in 2007. The observation was done from the end of November until the first week of December 2007 at the Faculty of Dentistry, University of Indonesia. One hundred and twenty eight subjects were selected by simple random sampling method and answered three questionnaires adopted from the RDC (Research Diagnostic Criteria), Diagnostic Index and Oral Parafunction. The data was analyzed by Fisher`s test.The results showed that bruxism prevalence was 15.6%, TMJ pain or stiffness was 8.6%, often experienced jaw stiffness when waking up in the morning was 3.1%, and 22.7% seldom experienced this symptom. Result for testing the relationship between bruxism and TMJ pain or stiffness was p=0.376 (p>0.05), hence we can conclude that there is no relationship between bruxism and TMJ pain or stiffness. Result for testing the relationship between bruxism and jaw stiffness when waking up in the morning was p=0.498 (p>0.05), which means that there is also no relationship between bruxism and jaw stiffness when waking up in the morning. In conclusion, there was no relationship between bruxism and pain or stiffness of TMJ on preclinical dental students of University of Indonesia in 2007."

"Temporomandibular Joint (TMJ) sound is on of TMJ dysfunction symptom that often reported by patient. The most common causes are considered to be poor coordination in lateral pterygoid muscle function, displacement of articular disc and irregularities in articular surface (articular eminence and condyle). A rescent study has reported that unilateral chewing habit caused differential loading when mandibular was moved. This may lead disc discplacement or dislocation and joint sounds in closing and/or opening movement. the purpose of this study was to clarify the relationshiop between unilateral chewing habit with presence of TMJ sounds. The subjects were 114 female and 14 male who study in Faculty of Dentistry- University of Indonesia with age, varying from 18-22 years old. Result, 45 subject (35,2%) have clicking or popping sounds and 20 subject (15,6%) have crepitation sound. Pearson Chi-square test shown that P was 0.413 for clicking or popping sounds and 0.352 for crepitation sound, P>0.05. In conclusion, there is no significant relationship between unilateral chewing habit with presence of TMJ sounds.

Salah satu gejala gangguan sendi tempomandibula (STM) yang sering dirasakan oleh penderita adalah bunyi sendi. Penyebab bunyi tersebut diyakini akibat buruknya koordinasi otot pterigoideus lateralis, displacement diskus artikularis dan iregularitas permukaan artikulasi (eminensia artikularis dan kondilus). Berdasarkan penelitian sebelumnya dinyatakan bahwa kebiasaan mengunyah unilateral dapat menyebabkan ketidak seimbangan distribusi beban kunyah saat mandibula digerakkan, yang mengakibatkan terjadinya displacement atau dislokasi pada diskus dan bunyi saat membuka dan atau menutup mulut. Dengan demikian penelitian ini bertujuan untuk mengetahui apakah terdapat hubungan antara kebiasaan mengunyah unilateral dengan terjadinya bunyi STM, yang dilakukan pada 128 subjek penelitian mahasiswa FKG UI umur 18-22 tahun yang terdiri dari 114 subjek perempuan dan 14 subjek laki-laki. Didapat hasil, sebanyak 45 orang (35,2%) memiliki bunyi click atau pop dan sebanyak 20 orang (15,6%) memiliki bunyi krepitasi (kresek-kresek). Pada analisa statistik menggunakan uji Pearson Chi-Square, menunjukkan nilai P adalah 0.413 untuk bunyi click atau pop dan 0.352 untuk bunyi krepitasi (kresek-kresek), P>0,05. Dengan demikian disimpulkan bahwa tidak terdapat hubungan antara kebiasaan mengunyah unilateral dengan terjadinya bunyi STM."

"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."

"Occlusal splint is commonly used for treatment of the temporomandibular joint disorder (TMD). It can be made of hard and soft material. Hard occlusal splint (HOS) which was known earlier had been recognized more effective then soft occlusal splint (SOS) which recently gained some popularity. This clinical study based on case series was to detemined which type of occlusal splint was more effective for TMD. This study involved 20 subjects and they were divided into HOS and SOS group with 10 subjects in each group. HOS was processed with heat curing acrylic and SOS with vacuum former. Before and after 4 weeks of treatment, 5 TMD symptoms (impaired range of movement, impaired TMJ function, muscle pain, TMJ pain and pain on movement of mandible) were measured using Helkimo diagnostic index. The results were analyzed with Kolmogorov-Smimov Z's test. The findings showed statistically significant improvement in impaired range of movement and muscle pain in favor of HOS group(p<0.05). Although they were not statistically significant, HOS group showed better improvement than SOS group in TMJ pain and pain on movement of the mandible. In TMJ's function, no changes werefound in both groups. In general, HOS was more effective than SOS for treating TMD in relatively short period of time. Despite of the phenomena, the popularity of SOS was not followed with its effectiveness."

"Latar Belakang: Prevalensi kecemasan pada mahasiswa lebih tinggi dibandingkan pada populasi umum.

Background: The prevalence of anxiety in college students are higher than in general population. This can be influenced by several factors, including academic, socioeconomic status, cultural, moral, and also biological factors. The high level of anxiety also increases the risk of temporomandibular disorder in college students.

Objective: This study aims to find out the association between anxiety and temporomandibular disorder, and also find out the association between gender, socioeconomic status (parental education and monthly family income), and cultural factor (origin) with anxiety and temporomandibular disorder in college students.

Methods: A cross-sectional study using online questionnaire of 527 students from University of Indonesia, that conducted on November 2021. There are two given questionnaires, State-Trait Anxiety Inventory that consisted of two part and 40 questions in total to assess anxiety, and Temporomandibular Disorder Diagnostic Index that consisted of 8 questions tao assess temporomandibular disorder.

Result: The chi-square test showed that there was a statistically significant difference (p<0.05) of temporomandibular disorder based on anxiety, either A-State or A-Trait. The kendall correlation test showed that temporomandibular disorder, have positive and weak statistically significant correlation to anxiety, either A-State or A-Trait. The chi-square test showed that there was a statistically significant difference (p<0.05) of anxiety, either A-State or A-Trait, based on gender. The kendall correlation test also showed that gender, have positive and weak statistically significant correlation to anxiety, either A-State or A-Trait. However, the continuity correction test showed that there was no statistically significant difference (p 0.05) of temporomandibular disorder based on gender. The chi-square test also showed that there was no statistically significant difference (p 0.05) of anxiety, either A-State and A-Trait, and temporomandibular disorder based on socioeconomic status (parental education and monthly family income) and cultural factor (origin).

Conclusion: There was an association between anxiety, either A-State or A-Trait, and temporomandibular disorder, as well as gender and anxiety, either A-State or A-Trait, in college students. However, no association was found between gender and temporomandibular disorder, as well as socioeconomic status (parental education and monthly family income) and cultural factor (origin) with anxiety,either A-State or A-Trait, and temporomandibular disorder in college students.

"Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 421-426Temporomandibular joint disorder may be caused by variety of factors; one of which is the posture of head and neck. However, the remains controversial and a subject of debate by experts. The objective of this study was to know whether there was a relation between temporomandibular disorders and the head and neck posture seen radiographically. Subject were 40 dental students from University of Indonesia who met the inclusion criteria, selected through questionnaire, and subjective examinations based on Helkimo's dysfuction index. Then, lateral cephalometries radiographic were done to all subjects. In the radiogram, a horizontal line was made from the nasion point to the sella tursica, and a vertical line was drawn along the prominent bone of C1 - C5. The angle between the two lines was measured, and used to represent the head and neck posture. The design of the study was cross sectional. Based on statistical analysis, there was no significant relationship between the anamnestic dysfunction index as well as the clinical dysfunction index that represented the temporomandibular joint disorders and the posture of head and neck seen radiographically."

Low back pain (LBP) often persists after lumbosacral fusion, and sacroiliac joint (SIJ) ishypothesized to be a source of pain. To date, there are no studies regarding the associationbetween lumbosacral fusion and SIJ pain in Indonesia. The objective of this study is toinvestigate the association between lumbosacral fusion and SIJ pain. We also investigatedthe characteristics and prevalence of post-lumbosacral fusion SIJ pain. This was a crosssectionalstudy. The study was conducted from June to September 2019. Subjects werepatients who underwent lumbosacral fusion at Cipto Mangunkusumo Hospital, Jakarta,Indonesia during the period between January 2015 and December 2018. A total of 43subjects were recruited for this study. Twenty-six (60.5%) subjects were female, and themean age was 57.65 􀁲 9,7years of age. In our study, the annual incidence of postlumbosacralSIJ pain in 2015, 2016, 2017, 2017 was 78.6%, 40%, 81.3%, and 87.5%,respectively. The median onset of SIJ pain 8 (4-14) months, and the median visualanalogue scale score was 4 (2-6). Gender, body mass index (BMI), and fusion level weresignificantly associated with the development of SIJ pain (p = 0.002, p = 0.001, and p =0.002, respectively).

"Pasen dan cara kerja : 30 pasen OA lutut (15 pria, 15 wanita) dengan peningkatan sudut Q (> 15°) yang memenuhi kriteria inklusi dan ekslusi kemudian dicatat derajat nyeri (Nilai VAS; Visual Analogue Scale), derajat OA (Klasifikasi Kellgreen & Lawrence) dan IMT. Selanjuinya dilakukan pemeriksaan pola ajakan otot vastus medialis dan vastus lateralis dengan EMG. Ditentukan awal ajakan otot vastus lateralis dibandingkan dengan otot vastus medialis. Grafik EMG dinilai pada tugas berdiri berjinjit dan berdiri dengan tumit. Hasil pemeriksaan kemudian dianalisa secara stalistik lalu dilihat hubungan antar variabel secara statistik.Hasil : Terjadi perubahan pola ajakan otot vastus lateralis dan vastus medialis pada seluruh naracoba penderita OA baik laki-laki dan perempuan dengan kenaikan sudut Q (>l5°). Terdapat hubungan signifikan berupa korelasi negatif (R = -0,663; p = 0,007) antara kenaikan sudut Q dan perubahan pola ajakan pada kelompok laki-laki dengan cara pemeriksaan berdiri berjinjit. Terdapat hubungan signifikan berupa korelasi negatif (R = -0,508; p = 0,002) antara pembahan pola ajakan dan derajat OA lutut pada nilai total (Gabungan kelompok pria dan wanita, n = 30) dengan cara pemeriksaan berdiri berjinjit. Terdapat hubungan signifikan berupa korelasi negatif (R = -0,692; p = 0,04) antara perubahan pola ajakan dan derajat OA lutut pada nilai kelompok Iaki-laki dengan cara pemeriksaan berdiri berjinjit.Kesimpulan : Walaupun seluruh naracoba penderita OA lutut dengan peningkatan sudut Q mengalami perubahan pola ajakan, namun hubungan yang terjadi tidak sesuai dengan teori dasar. Terdapat hasil pemeriksaan perubahan pola ajakan yang tidak terdistribusi normal, baik berdiri berjiniit maupun berdiri dengan tumit. Hal ini, diduga sebagai penyebab timbulnya hasil-hasil yang tidak menunjang hipotesis. Penyebabnya mungkin akibat adanya faktor-faktor lain yang tidak termasuk dalam kriteria inklusi dan elslusi seperti kekakuan(rightness) jaringan lunak bagian lateral, kekendoran (laxity) jaringan lunak bagian medial, displasia tulang dan posisi abnormal patella.

Subject and Interventions : 30 pts knee OA (15 men, 15 women) with increased Q - angle (>15°) and passes exclusion and inclusion criteria, have been registered entering the EMG study on medial and lateral vastus recruitment pattern atter noted on the pain scale, knee OA grade, and BMI. The starting point of recruitment is determined using the EMG on muscle activity visualization Comparison of medial and lateral vastus recruitment starting point, concluded as the altered recruitment pattern. The EMG examination is conduct in the rock on toe and heel test. All of data was analyzed using statistic software, to determine the correlation between all variables.Results : All of the patients with increased Q-angle shows altered recruitment pattern. There is a significant negative correlation between increased Q-angle and altered recruitment pattern in male group with rock on toe test (R = -0,663; p = 0,007). The significant negative correlation occurs between altered recruitment pattern and the knee OA grade in the total value (male+female group, n=30) with rock on toe test (R = -0,508; p = 0,002). Significant negative correlation also occurs between altered recruitment pattern and the knee OA grade in the male group with rock on toe test (R = -0,692; p = 0,04).Conclusion : Even all of the knee OA patients with increased Q-angle shows altered recnritment pattern, the correlation occurs in different way with the theory. The results have not been support the hypothesis owing to the fact that the recruitment pattern data is not nomtally distributed and another factors which are not include in the exclusion criteria may affect the pain and knee OA grade. Those factors are lateral solt tissue tightness, medial soft tissue laxity, dysplastic bone and patella position abnomarlity."
