"Background: Early operated patients with orofacial cleft often develop a retrusive maxilla. It is not clear whether this growth disturbance is attributed to the congenital malformation itself or to the cleft surgery or both. Objective: To evaluate transversal and anterio-posterior maxillary development in unoperated adult patients with unilateral cleft lip and palate (UCLP). Methods: 68 dental casts of unoperated adult UCLP patients were compared to 24 adult controls. The casts were analysed three dimensionally using an industrial coordinate measuring machine (=CMM) (Zeiss Numerex; Carl Zeiss Stutgart, Germany). 12 cephalograms of unoperated UCLP patients and 24 controls were available and measured for the following variables: Maxillary length, SNA, SNB, Gonial angle and SN-FH angle. The data obtained was analysed by paired t-test, level of significance was set at p<0,05. Results: measured on dental casts, the transversal distance at the level of the second molars was significantly wider and at the level of first premolar and canine significantly smaller compared to the control group. Cephalometrically there were no significant differences for the 5 cephalometric measurements. Conclusions: the presence of a cleft influences the development of the maxilla: The more extensive the cleft, the more extensive the effect of the dental arch, but the compression of the maxillary arch is limited to the anterior region. Measured cephalometrically the cleft has no influence on the anterio-posterior development of the maxilla. However, the sample size for the cephalometric study was small."

"Salah satu syarat "die" adalah tidak mudah mengalami abrasi atau goresan ketika pembuatan pola malam dan percobaan "casting". Pengamatan menunjukkan bahwa umumnya para dokter gigi maupun teknisi tidak melakukan pengadukan dental stone tipe IV menurut instruksi pabrik ataupun aturan standar. Dengan demikian, dapat diduga hasil akhir die yang diperoleh, kekerasannya tidak sebaik kekerasan dental stone yang diaduk sesuai dengan instruksi pabrik ataupun aturan standar, sehingga dapat mempengaruhi "fitness" restorasi cekat. Untuk itu, dilakukan penelitian cara pengadukan dental stone tipe IV yang sesuai dengan instruksi pabrik dan tidak menyalahi aturan standar untuk mengetahui pengaruh cara pengadukan terhadap kekerasan dental stone tipe IV. Pengadukan dilakukan dengan menggunakan mesin kondisi hampa udara, mesin kondisi tanpa hampa udara dan manual. Uji kekerasan dilakukan menggunakan alat indentasi "Vickers Hardness Tester" dengan beban 31,25 kg. Indentasi dievaluasi menggunakan "Frank Hardness Microscope". Gambaran rnikro dari permukaan spesimen dievaluasi dengan "Scanning Electron Microscope". Hasil uji Anova 1-arah dan test Scheffe menunjukkan perbedaan bermakna antara ketiga cara pengadukan (< 0,05). Disimpulkan bahwa cara pengadukan yang mengicuti instruksi pabrik dan menggunakan mesin hampa udara dapat meningkatkan nilai kekerasan dental stone tipe IV.

In the effort of producing a well-fit restoration, die material should be hard enough to resist scratch and abrasion during the wax-up and try-in procedures. Unfortunately, in mixing the dental stone type IV for working model and die, many dentists and dental technicians neglect the direction for use given by the manufacturer. It is assumed, that the hardness is lower by then, but not enough scientific proof has been reported. For this reason, a study is conducted to investigate the influence of spatulation on the hardness of the type 1V dental stone. The sample groups were divided into 3 groups. Each group was mixed differently, one group using a vacuum machine, one group using non vacuum machine and one group manually. Hardness was measured by means of Vickers indentor with 31.25 kg load. The indentation was evaluated using Frank Hardness Microscope. The surface of the samples were examined with SEM. One-way Anova and Scheffe test showed that each group differed significantly one to other (< 0.05). It can be concluded that the result gained with vacuum machine mixing is harder than by the other mixing procedures."

"ABSTRAKTujuan: Untuk menganalisis perbedaan sefalometri morfologi wajah di antara orang dewasa dengan UCLA, UCLP, BCLA dan BCLP yang tidak dioperasi dibandingkan dengan kelompok kontrol (non-cleft). Bahan dan metode: Penelitian retrospektif ini menganalisis sefalogram dari subjek dengan UCLA (n= 160), UCLP (n=59), BCLA (n=21) dan BCLP (n=13) dibandingkan kelompok kontrol/non-cleft (n= 52). Sefalogram dipindai pada 16-bit scanner flat bed (EPSON Expression 10000XL) pada resolusi 300 dpi. Semua sefalogram yang diubah menjadi digital oleh seorang pengamat komersial memakai software (Viewbox 3 dhal Software, Kiffisia, Yunani). Sefalometri dianalisis sesuai dengan protokol modifikasi Eurocleft. Perbedaan sefalometri morfologi wajah di antara mereka dianalisis secara statistik. Hasil: Posisi maksila (s-n-ss/SNA), posisi mandibula (S-N-Pg) dan hubungan rahang sagital (ss-n-sm/ANB) berbeda secara signifikan antara kelompok kontrol dan semua kelompok cleft (nilai p antara 0.001 dan 0.042); kelompok cleft sudutnya lebih besar dibandingkan kelompok kontrol. Posisi maksila dan mandibula arah antero posterior berbeda antara kelompok UCLA dan UCLP, juga antara kelompok BCLA dan BCLP. Inklinasi gigi insisif atas terhadap palatal plane (ILS/NL) dan sudut interincisal tidak berbeda secara signifikan antara kelompok kontrol dan semua kelompok cleft. Kesimpulan: Pada kelompok cleft dewasa yang tidak dioperasi, rahang atas menunjukkan secara morfologis lebih ke depan (s-n-ss / SNA) daripada kelompok kontrol. Morfologi wajah kelompok cleft dewasa yang tidak dioperasi tampaknya dapat tumbuh normal pada arah anteroposterior. Setiap jenis cleft memiliki karakteristik sefalometri morfologi sendiri.

ABSTRACTObjective: To analyze cephalometric facial morphology among adult, unoperated UCLA, UCLP, BCLA. BCLP and the control group (non-cleft). Materials and methods: This retrospective study analyzed the cephalograms of 160 subjects with UCLA, 59 with UCLP, 21 with BCLA, 13 with BCLP and 52 the control (non-cleft group). The cephalograms were scanned on a 16-bit flatbed scanner (EPSON Expression 10000XL) at a resolution of 300 dpi. All cephalograms were digitized by one observer with commercially available software (Viewbox 3 dHal Software, Kiffisia, Greece). The lateral cephalograms were analyzed according to a modified Eurocleft protocol. Differences in cephalometric facial morphology among them were analyzed statistically. Results: Maxillary prominence (s-n-ss/SNA), mandibular prominence (S-N-Pg) and sagittal jaw relationship (ss-n-sm/ANB) differed significantly between the control group and all cleft groups (p-values between 0.001 and 0.042), being larger in the cleft groups. Maxillary and mandibular prominence differed between UCLA and UCLP and either BCLA and BCLP. Upper incisor inclination to palatal plane (ILS/NL) and the interincisal angle did not differ significantly between the control and all cleft groups. There was also no significant difference between the unilateral cleft groups and between the bilateral cleft groups. Conclusions: In the adult unoperated cleft groups, the maxilla showed more prominent (s-n-ss/SNA) than the control group. The facial morphology of adult untreated cleft groups seems potentially normal development in anteroposterior direction. Each type of cleft has its own characteristic cephalometric morphology"

The temporomandibular disorders (TMD) are a group of disorders involving the temporomandibular joint, muscles, and surrounding structures. Dentists or dental specialists often encounter challenges when dealing with TMD patients. It is unknown how the knowledge, attitudes, and behavior of dentists and dental specialists in Indonesia are in dealing with TMD patients. The etiology of TMD is multifactorial and one of the treatments is orthodontic treatment. On the other hand, orthodontic treatment is thought to be one of the causes of TMD due to changes in the position of the teeth, mandibles, and the location of the condyle. This can be seen through clinical conditions and cephalometric radiographs. Temporomandibular joint disorders can become inflammatory so inflammatory biomarkers are widely studied. Objective: The research consists of two stages. Phase I (Qualitative) aims to obtain a measurement/questionnaire of operator’s ability (dentists and dental specialists) about knowledge, attitudes, and behavior towards patients with TMD (PSP-TMD Questionnaire), which is valid and reliable. Phase II (Quantitative) aims to obtain TMD risk prediction index based on operator capability (PSP-TMD questionnaire score), clinical conditions related to clinical factors (age, malocclusion type, overjet, overbite, and TMD etiology index), clinical conditions related to mechanical factors (bracket type, extraction case, and auxiliary tools), cephalometric radiographs (ANB, SN-MP, Go Angle, I-I and Y-Axis angles), and biomarkers of inflammation (IL-1β and CRP) Method: The research was approved by the Dental Ethics Committee, FKG-UI, No: 11/Ethical Approval/FKGUI/III/2022 and conducted at the Orthodontics Clinic and Oral Biology Laboratory, RSKGM, FKG UI, Jakarta, Indonesia, in November 2021-January 2024. Phase I involves creating questionnaires through literature review, observation, and focus group discussion (FGD) by 10 dentists and dental specialists. The FGD results were analyzed using the Framework method followed by face and content validity tests using Aiken's V, I-CVI, and I-CVR analysis. Questionnaires were tested using validity tests (Spearman correlation) and reliability tests (Cronbach's Alpha and CITC). Every stage and testing related to the substance is discussed and revised by experts. The final questionnaire (PSPGSTM Questionnaire) was tested on 370 respondents and Orthodontics residents (operators) who treated subjects in phase II research. The phase II study was conducted on 105 subjects of orthodontic post-treatment patients who were called back to sign an informed consent and fill in the TMD etiology index, DC/TMD examination, and buccal mucosal swabs. Other data were supplemented from questionnaire scores, medical records, and cephalometric radiographs. Bivariate analysis was performed to see the relationship of each variable with TMD and multivariate multiple logistic regression. Results: The PSP-TMD measurement tool/questionnaire contained 73 statements, consisting of 50 knowledge domain statements, 14 attitude domain statements, and nine behavior domain statements. The knowledge domain consists of 12 sign and symptom subdomain statements, 14 etiology subdomain statements, 11 diagnosis subdomain statements, and 13 treatment subdomain statements. The PSP-TMD questionnaire has good validity and reliability. The TMD risk prediction index was generated with four predictor factors, namely the TMD etiology index, auxiliary tools, SN-MP, and Go Angle. Conclusion: The capability of dentists and dental specialists regarding knowledge, attitudes, and behavior towards patients with TMD can be measured using the PSP-TMD questionnaire. The TMD risk prediction index consisting of the TMD etiology index, auxiliary tools, SN-MP, and Go Angle can be used to predict risk factors for TMD"

"Latar Belakang: Hipertrofi adenoid merupakan kelainan pada kelenjar adenoid yaitu berupa membesarnya ukuran dari kelenjar adenoid. Hipertrofi adenoid pada usia anak-anak dianggap suatu hal yang umum sebagai bagian dari mekanisme pertahanan tubuh. Obstruksi saluran pernapasan oleh hipertrofi adenoid dapat menimbulkan kebiasaan buruk mouth breathing yang jika tidak segera ditangani dapat mengakibatkan efek berkepanjangan seperti long face syndrome atau adenoid facies, rongga mulut kering, maloklusi dan postur tubuh yang cenderung membungkuk. Oleh sebab itu, ukuran adenoid dianggap penting karena tidak hanya berpotensi mempengaruhi fungsi respirasi, namun juga bila terjadi pada usia anak-anak dapat berdampak pada kelainan tumbuh kembang kraniofasial. Tujuan: Mengetahui nilai rata-rata rasio adenoid terhadap bony nasopharynx structure pada anak usia 6-15 tahun sebagai kelompok berisiko mengalami obstruksi saluran pernapasan atas akibat hipertrofi adenoid di RSKGM FKG UI. Metode: Studi cross-sectional dengan rasio adenoid terhadap bony nasopharynx structure pada 126 sampel radiograf sefalometri lateral digital laki-laki dan perempuan usia 6-15 tahun yang diukur menggunakan aplikasi I-Dixel Morita. Uji kesesuaian pengukuran intraobserver dan interobserver dilakukan menggunakan uji ICC dan Kappa. Analisis deskriptif dilakukan untuk setiap parameter pengukuran pada setiap kelompok usia. Hasil: Nilai rerata rasio adenoid terhadap bony nasopharynx structure menunjukkan nilai terbesar 0,70 ± 0,009 (SD) pada usia 6 tahun dan terkecil terdapat pada kelompok usia 15 tahun yaitu, 0,54 ± 0,05 (SD). Hasil pengukuran dan evaluasi lebar nasofaring menunjukkan bahwa lebar nasofaring dengan kategori normal terbanyak terdapat pada usia 15 tahun. Kesimpulan: Nilai rata – rata rasio adenoid terhadap bony nasopharynx structure menunjukkan kecenderungan penurunan seiring bertambahnya usia. Sementara itu, lebar nasofaring menunjukkan kecenderungan peningkatan seiring bertambahnya usia.

Background: Adenoid hypertrophy is an abnormality of the adenoid gland, characterized by its enlargement. It is common in children as part of the body's defense mechanism. Obstruction of the respiratory tract caused by adenoid hypertrophy can lead to the development of mouth breathing habits, which, if not treated promptly, can result in long-term effects such as long face syndrome, adenoid facies, dry mouth, malocclusion, and poor posture. Therefore, adenoid dimensions are important not only because they potentially affect respiratory function, but also because they impact craniofacial growth and development if it occurs in children. Objective: To determine the average ratio of the adenoid to the bony nasopharynx structure in children aged 6-15 years, a group at risk of upper respiratory tract obstruction due to adenoid hypertrophy at RSKGM FKG UI. Methods: This cross-sectional study measured the ratio of the adenoid to the bony nasopharyngeal structure in 126 digital lateral cephalometric radiographs of both male and female children aged 6-15 years, using the I-Dixel Morita application. Intraobserver and interobserver reliability were assessed using the ICC and Kappa tests. Descriptive analysis was performed for each measurement parameter across different age groups. Results: The mean adenoid-to-bony nasopharynx structure ratio was highest at 0.70 ± 0.009 (SD) in the 6-year-old group and lowest at 0.54 ± 0.05 (SD) in the 15-year-old group. In the evaluation of nasopharyngeal width, the highest normal category was observed in the 15-year-old group. Conclusion: The mean adenoid-to-bony nasopharynx structure ratio showed a tendency to decrease with age, while the nasopharyngeal width showed a tendency to increase with age."
