“…Sülün et al [4,8] proposed that a steep slope of the eminence forms a basis for the development of reducing disc displacement. Ren et al [11,15,12] described that the reduced eminence height could be due to degenerative changes in the bone or in the process of remodeling. A steep slope of the eminence is more apparent in asymptomatic individuals than in patients with TMD s. [4] Previous studies reported a lower eminence height in women compared to men.Keller and Carano reported that in asymptomatic patients a low eminence angle can be a predisposing factor for TMDs and hence angle between the occlusal plane and the eminence ridge is lower in patients with TMDs [4] .…”

Temporomandibular joint (TMJ) is a unique joint. The dimension joint space is determined by the optimal Condylar position. Conventional radiographs cannot exactly show the relationship hence MRI and CT are being used frequently for imaging of TMJ. CBCT has recent advancement into technology especially in this field as helped to analyse the TMJ in more comphrehensive manner. The aim of this study is to assess the position of condyle in TMJ with patients of TMDs. The importance of relationship between condyle and glenoid fossa remains controversial. The CBCT utilizes less radiation and as higher resolution than normal CT. The position of condyle in the glenoid fossa is measured with high accuracy using CBCT technique for reconstruction and imaging of the TMJ. It provides reliable and accurate images. The study was designed to compare the condylar morphology in symptomatic and asymptomatic patients with TMD s.

“…Hal ini selaras dengan penelitian Ozkan dkk yang menyatakan bahwa bentuk sigmoid menunjukkan insidensi terbesar yang kemudian diikuti oleh bentuk box. 14 15 Hal ini dapat terjadi karena eminensia artikularis mengalami pertumbuhan aktif dalam arah horizontal dan vertikal pada fase postnatal sejak usia 6 bulan. Pertumbuhan dalam arah horizontal dilihat dari pergerakannya ke anterior, sedangkan pada pertumbuhan dalam arah vertikal terjadi dalam 3 fase : pada usia 6 bulan saat erupsi gigi pertama, antara usia 5 -6 tahun saat erupsi molar dan pada usia 9 -12 tahun, sehingga memengaruhi fungsi pengunyahan.…”

“…Berbeda dengan penelitian sebelumnya yaitu penelitian Cohen dkk, hasilnya menunjukkan bahwa variasi bentuk eminensia terjadi pada semua kelompok usia. 15 Variasi tersebut terjadi karena pada rentang usia ini pertumbuhan dan perkembangan eminensia artikularis berjalan lambat serta adanya perubahan oklusi dari gigi desidui ke gigi permanen serta kebiasaan buruk yang dapat berpengaruh terhadap perubahan bentuk pada struktur TMJ. 18 Usia 21 -30 tahun pertumbuhan komponen temporal telah mencapai 92%, pada rentang usia ini komponen temporal hanya mengalami penyempurnaan dan perkembangan, sehingga bentuk dari eminensia artikularis semakin stabil.…”

Perubahan bentuk, ukuran eminensia artikularis dan fossa glenoidalis selama masa pertumbuhan perlu diketahui karena berperan penting dalam pergerakan sendi temporomandibular, sehingga membantu menegakkan diagnosa ada tidaknya kelainan pada tumbuh kembang. Variasi serta perubahan dapat dilihat dan diukur melalui radiograf panoramik. Tujuan penelitian ini untuk meneliti bentuk dan inklinasi eminensia artikularis serta kedalaman fossa glenoidalis berdasarkan usia ditinjau dari radiograf panoramik. Metode: Jenis penelitian deskriptif dengan teknik pengambilan sampel purposive sampling. Jumlah sampel didapat dengan menggunakan rumus Slovin, sebanyak 60 radiograf panoramik pasien RSGM Unpad, bulan Januari-Mei 2018 dengan rentang usia 5-30 tahun dibagi kedalam tiga kelompok usia berdasarkan usia pertumbuhan komponen temporal. Bentuk eminensia, inklinasi eminensia dan kedalaman fossa diukur menggunakan software ImageJ. Data diolah menggunakan Microsoft Excel ® untuk mengetahui nilai minimum, maksimum, nilai rerata, dan standar deviasi. Hasil: Mayoritas bentuk eminensia artikularis pada tiap kelompok usia adalah sigmoid. Rerata inklinasi eminensia artikularis adalah 42°, rentang usia 5-10 tahun, 44° pada rentang usia 11-20 tahun, dan 58° pada rentang usia 21-30 tahun. Rerata kedalaman fossa glenoidalis adalah 4,62 mm pada rentang usia 5-10 tahun, 5,71 mm pada rentang usia 11-20 tahun, dan 7,52 mm pada rentang usia 21-30 tahun. Simpulan: Bentuk mayoritas eminensia artikularis selama masa pertumbuhan adalah sigmoid, serta inklinasi eminensia artikularis dan kedalaman fossa glenoidalis nilai reratanya semakin meningkat seiring dengan pertambahan usia selama masa pertumbuhan. Eminensia artikularis dan fossa glenoidalis mengalami fase pertumbuhan aktif pada rentang usia 5-10 tahun, berjalan lambat pada rentang usia 11-20 tahun, dan mengalami penyempurnaan serta perkembangan pada rentang usia 21-30 tahun.Kata kunci: sendi temporomandibular; eminensia artikularis; fossa glenoidalis; usia; radiograf panoramik Morphology and inclination of articular eminence and glenoid fossa depth based on age observed in panoramic radiographABSTRACT Introduction: Changes in the morphology and size of the articular eminence and the glenoid fossa during the growth period need to be known because it plays an essential role in the movement of the temporomandibular joint, thus helping to diagnose the presence or absence of abnormalities in the growth and development. These variations and changes can be seen and measured through panoramic radiographs. The purpose of this study was to examine the morphology and inclination of the articular eminence and the depth of the glenoid fossa based on age observed from a panoramic radiograph. Methods: This research was descriptive with a purposive sampling technique. The number of samples obtained using the Slovin formula, which resulted in 60 panoramic radiographs of the patients from Universitas Padjadjaran Dental Hospital (RSGM Unpad), during the period of January-May 2018, with an age range of 5-30 years, di...

“…However, not all patients with dislocation possess a steep AE slope. There have been many studies on the treatment of dislocation [7,8,10] or the relationship between the morphology of AE and disc displacement [11][12][13][14][15][16][17][18][19][20], but almost no studies have been found on the relationship between the morphology of AE and dislocation except for the study of Cohen et al [21]. In their study [21], the morphology of AE did not affect the anterior dislocation of the TMJ.…”

This study aimed to broaden our understanding of the predisposing factor and treatment of dislocation by analyzing and evaluating the morphology of the articular eminence (AE) in subjects with temporomandibular joint (TMJ) dislocation using cone beam computed tomography (CBCT).Methods: Methods: The subjects were divided into two groups: dislocation (31 subjects) and control (32 subjects). CBCT was used to examine 126 TMJs in 63 subjects (26 males, 37 females). The height, width, and posterior slope of the AE were measured in the parasagittal plane. The posterior slope was measured using the "top-roof line angle (TR angle)" method and the "best-fit line angle (BF angle)" method. The AE on the left side (AEL) and the AE on the right side (AER) of the subjects in the dislocation group were separately analyzed and compared with the control group after taking measurements. The average value of both sides was used when comparing with subjects with bilateral dislocation.Results: Results: Dislocations were more frequent in females (67.7%) than in males (32.3%). The dislocation group showed a gentler TR angle than the control group in the AER and in the average of AE on the both sides (AEB). The same group also showed a wider AE in the AEL and the AER (p<0.05). In subjects with unilateral dislocation, the width of the AE with dislocation was narrower and the TR angle and BF angle was steeper than the other side without dislocation (p<0.05). Conclusions: Conclusions:In subjects with unilateral TMJ dislocation, the posterior slope of the AE is steeper, and the width is narrower at the site of dislocation compared to the site without dislocation. However, in subjects with bilateral TMJ dislocation, AEB were wider, and the mean value of the posterior slope of AEB was gentler than that of the control group.
