"Latar Belakang: Perubahan degeneratif pada TMJ dapat menyebabkan perubahan morfologi kondilus mandibula. Salah satu faktor yang mempengaruhi perubahan degeneratif TMJ yaitu kehilangan gigi posterior yang tidak diganti. Modalitas CBCT memberikan gambar multiplanar bidang aksial, sagital dan koronal sehingga mempermudah visualisasi TMJ secara menyeluruh, sehingga CBCT dapat menjadi modalitas alternatif untuk mengevaluasi keadaan TMJ terutama morfologi kondilus. Penelitian ini dilakukan untuk meneliti perubahan morfologi kondilus mandibula pada evaluasi CBCT yang berhubungan dengan jumlah kehilangan gigi posterior, kelompok usia dan jenis kelamin. Tujuan: Mengetahui hubungan perubahan morfologi kondilus mandibula berdasarkan jumlah kehilangan gigi posterior pada kelompok usia 30 – 45 tahun dengan kelompok usia 55 – 70 tahun pada evaluasi CBCT. Metode: Penelitian ini merupakan penelitian retrospektif analitik cross sectional. Pengumpulan sampel dilakukan menggunakan metode Non-Probability Sampling dengan teknik Purposive Sampling dan didapatkan sebanyak 70 sampel volume data CBCT. Rekonstruksi dilakukan menggunakan Software CS Imaging Patient Browser 7.0.23 dan CS 3D Imaging v3.8.7. Carestream Health Inc. Kondilus mandibula dibedakan antara sisi kanan dan kiri, hasil rekonstruksi diambil dari potongan sagital dan koronal anteroposterior. Pengamatan dilakukan dua orang, sebanyak dua kali dalam jangka waktu berbeda dan jarak waktu dua minggu. Uji reliabilitas hasil pengamatan dilakukan menggunakan Uji Cohen’s Kappa dan hasil uji intraobserver dan intraobserver menunjukan angka 0.814 – 1.000 yang termasuk dalam kategori almost perfect agreement. Hasil: Terdapat hubungan yang bermakna antara perubahan morfologi kondilus mandibula dengan jumlah kehilangan gigi posterior pada kelompok usia 30 – 45 tahun dan kelompok usia 55 – 70 tahun dalam bentuk erosi, flattening, dan sklerosis (p= <0.005). Pada variabel jenis kelamin tidak ditemukan hubungan yang bermakna (p= >0.005). Kesimpulan: Dari keseluruhan hasil penelitian dapat ditarik kesimpulan bahwa semakin banyak jumlah kehilangan gigi dan semakin bertambahnya usia, memiliki hubungan dan dapat menyebabkan terjadinya perubahan morfologi kondilus mandibula.

Background: Degenerative changes in the TMJ can lead to changes in the morphology of the mandibular condyle. One of the factors that affect degenerative changes in the TMJ is the loss of posterior teeth that are not replaced. CBCT modality provides multiplanar images in axial, sagittal, and coronal planes making it easier to visualize the TMJ thoroughly, therefore CBCT can be an alternative modality to evaluate the TMJ condition, specifically the morphology of the condyles. This study aimed to examine the morphological changes of the mandibular condyle on CBCT evaluation with the number of missing posterior teeth, age group, and gender. Objective: To determine the relationship between changes in the morphology of the mandibular condyle based on the number of missing posterior teeth in the age group 30-45 years and the age group 55-70 years. Methods: This study is a cross-sectional analytic retrospective study. Sample collection was carried out using the Non-Probability Sampling method with the Purposive Sampling technique. Reconstruction was performed using CS Imaging Patient Browser 7.0.23 and CS 3D Imaging v3.8.7 Software from Carestream Health Inc. The mandibular condyle was divided into right and left, and the results of the reconstruction were taken from the sagittal and coronal anteroposterior sections. Observations were made by two people, two times in different periods with an interval of two weeks. The reliability test from the observations using Cohen's Kappa test and the results showed almost perfect agreement category with Kappa value 0.814 - 1.000. Results: There was a significant relationship between changes in the morphology of the mandibular condyle in the form of erosion, flattening, and sclerosis with the number of missing posterior teeth in the age group 30-45 years and the age group 55-70 years (p = <0.005). In the gender variable, there was no significant relationship with changes in the morphology of the condyle (p = > 0.005). Conclusion: It can be concluded that the greater number of missing teeth and the older the subject gets has relationship with and can cause changes in the morphology of the mandibular condyle."

"Besar pembukaan mulut dapat digunakan untuk menilai fungsi sendi temporomandibula. Ukuran besar pembukaan mulut bervariasi, namun di Indonesia belum ada data mengenai rata-rata besar pembukaan mulut. Tujuan penelitian ini adalah untuk mengetahui rata-rata besar pembukaan mulut masyarakat Indonesia dan menganalisis hubungannya dengan jenis kelamin dan tinggi badan. Penelitian dilakukan dengan metode potong lintang pada 182 subjek berusia 17–22 tahun dari mahasiswa Universitas Indonesia. Hasil uji analisis t tidak berpasangan menunjukkan perbedaan yang signifikan antara rata-rata besar pembukaan mulut wanita dan laki-laki (p<0.05), dengan rata-rata laki-laki (44.8-4.9mm) lebih besar dibandingkan wanita (37.6-4.9mm). Hasil uji analisis ANOVA menunjukkan perbedaan yang signifikan pada rata-rata besar pembukaan mulut antar kelompok tinggi badan (p<0.05). Oleh karena itu, terdapat hubungan antara besar pembukaan mulut dengan jenis kelamin dan tinggi badan.

Mouth opening can be used for assessing the function of temporomandibular joint. The average of mouth opening data differs in various population and the aim of this study is to investigate the mean of normal mouth opening in Indonesian population and to analyze the difference in between gender and height groups. Cross sectional study was conducted on 182 subjects aged 17 - 22 from Universitas Indonesia. Independent t test showed significant differences between male and female (p<0.05), with male (44.8-4.9mm) significantly higher than female (37.6-4.9mm). One way ANOVA test also showed significant difference between the higher and lower height groups (p<0.05). Thus, mean mouth opening differ significantly in between gender and height groups."

"Temporomandibular disorder (TMD) usually has non-specific signs and symptoms. The patient generally can only feel the pain, and thus complains about the stomatognatic problems without knowing the cause and the source. When the patient's chied compaint is pain, it is important to identify the source of the problem in order to provide appropriate treatment. Applied treatments for TMD can vary enormously. A female patient, age 35, came to the prosthodontic clinic with the chief complaints of pain in the right joint and limitation in mouth opening for past 7 years. In the last 2 weeks, the complaints worsened. With light pressure she could still open her mouth wider but showing deviations. She also complained about headache, tension in the forehead region, and muscle pain in the upper back body. The patient also reported that she has been chewing only on the right side for more than 20 years. Lateral transcranial x-ray showed that there were no visible structural or positional disorders. Thus, jaw exercise was decided as the initial therapy for the patient. WIthin one week, all complaints dissapeared. It was concluded that jaw exercise was a very useful form of treatment for TMD provided that the correct diagnosis is established."

"Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 155-158The causes of TMD are complex and multifactorial, therefore the management should be done by several disciplines. ln this report, a 27-year-old man came to the teaching hospital of the University of Indonesia Faculty of Dentistry's Prosthodontic Department complaining about clicking sound and pain around his right joint. He received orthodontic treatment 9 years ago with removable appliance at a private practice and had 4 premolar extraction. The patient's face looked asymmetric, with a low vertical dimension, a Class II occlusion, and an anterior deep bite. Besides that, he clenched his teeth during emotional stress. Lateral tanscranial photo showed that the position of the left condyle was relatively normal or slightly anterior, and the right condyle was in the superoposterior position in the fossa with an abnormal shape. To solve this problem, the patient was referred to the Orthodontic Deparment to get a correct vertical dimension and normal anterior overbite. After 6 years, the patient was again referred to the prosthodontic Department, but the result was not successful. In order to get the right vertical dimension, an occlusal splint was fabricated to achieve a comfort jaw relation. In this position, the overbite was 2 mm, but space between the upper and lower posterior teeth was 5 mm. In this situation, full veneer crowns were not impossible to fabricate. Finally, to maintain this comfort position, the patient was suggested to wear the occlusal splint and come regularly for control every 6 months."
