Cleft lip and palate is one of the most common congenital anomalies. Cleft lip and palate patients encounter growth problems in lip and palate area, although their overall growth and development remains unknown. Cervical vertebral maturation are indicators of physiological maturation used in interceptive treatment and orthognathic surgery. The present study aims to determine physiological maturation stage of cervical vertebrae maturation index in cleft andnon-cleft patients. Lateral cephalogram of 26 cleft patients and 27 non-cleft patients with a range of chronological age from 8-16 years old were involved. The cervical vertebrae maturation were analyzed in six stages of cervical vertebrae maturation method of Hassel and Farman. Data were analyzed using t-test (p≤ 0.05). The result shows that physiologicalmaturation stage of cervical vertebrae maturation index in cleft and non-cleft patients has no significant difference in stage acceleration (p= 0.38), stage transition (p= 0.41) and deceleration (p= 0.39). Likewise, there is no significant difference in physiological maturation stage of cervical vertebrae maturation index between cleft and non-cleft patients.

Introduction: Power chains is the common device used in fixed orthodontic treatment. Force decay in power chains is a problem that can affect the teeth movement due to a continuous force cannot be maintained. Force decay in power chain can be affected by the use of alcohol-containing mouthwash or alcohol-free mouthwash. The objective of this study was to determine the effect of alcoholic-containing mouthwash, alcohol-free mouthwash, and artificial saliva towards the power chains force decay. Methods: This research was an experimental analytic laboratory in-vitro with the comparative approach. The sample in this study were 40 power chain, short A (SA); 40 power chain, short B (SB); 40 power chain, long A (LA); and 40 power chain, long B (LB), which divided into 5 groups that were consecutively exposed to the artificial saliva as control group; Minosep® with 0.1% of chlorhexidine gluconate; Listerine® with 0% of alcohol; Hexadol® with 9% of alcohol; and Listerine® with 26.9% of alcohol. The measurement of force decay was performed with digital force gauge on day 0, 1, 14, and 28. The statistical analysis was done by using the Wilcoxon and Mann-Whitney tests. Result: There was a significant difference (p<0.05) between the force decay of power chain that exposed to the alcohol-containing mouthwash, alcoholfree mouthwash, and the artificial saliva. Conclusion: The force decay level of power chain that exposed to an alcohol-containing mouthwash was higher compared to the force decay level of power chain that exposed to an alcohol-free mouthwash and an artificial saliva.

The purpose of this study was to find out whether there were changes in occlusal plane inclination after fixed orthodontic treatment of bimaxillary protrusion cases where extraction of four first premolars were needed using the standard Edgewise appliances. The sample were fourteen orthodontic patients, aged above sixteen years old, no sexual discrimination, treated with fixed appliances at Orthodontic Specialist Clinic Faculty of Dentistry Universitas Padjadjaran. The method was pre-post design which compared occlusal plane inclination obtained from tracings of lateral cephalograms before and after orthodontic treatment. The results were calculated with the paired t-test analysis. The study revealed that there were no significant changes in occlusal plane inclination after the orthodontic treatment.

Introduction:The base surface roughness of slot bracket can affect friction in tooth movement. There are ISO-certified and non-ISO-certified stainless steel brackets on the market. Thus orthodontists must be careful in choosing the right bracket. This study was aimed to evaluate the differences of the surface roughness of ISO-certified and non-ISO-certified Roth 0.022 inch stainless steel bracket with the parameter of S a (average roughness). Methods: This research was a laboratory observational. Samples were taken randomly as many as 32 brackets divided into two groups, each consisted of two bracket brands. Surface roughness measurements were performed using an atomic force microscope (AFM), then the data were analysed by ANOVA test (p < 0.05) and Post-Hoc analysis. Results: The ISO-certified bracket has an S a value smaller than the non-ISO-certified bracket. There was a significant difference in the surface roughness of the ISO-certified and non-ISO-certified slot bracket base (p < 0.05). Conclusion: The ISOcertified bracket has a smoother base surface than the non-ISO-certified bracket base.

Pendahuluan: Pasien yang telah melewati masa tumbuh kembang dapat dirawat dengan perawatan ortodonti kamuflase atau bedah ortognati. Perawatan ortodonti kamuflase dengan hasil yang cukup baik dapat dilakukan jika diskrepansi skeletal tidak terlalu berat. Laporan kasus ini bertujuan untuk mengetahui keefektifan penatalaksanaan perawatan maloklusi skeletal kelas III dengan perawatan ortodonti kamuflase. Laporan kasus: Pasien perempuan, berusia 16 tahun 7 bulan, datang ke klinik PPDGS Ortodonti RSGM UNPAD dengan keluhan gigi depan tidak rapi dan gigi bawah terlihat lebih maju dibandingkan gigi rahang atas. Hasil diagnosis menunjukkan maloklusi dentoskeletal kelas III disertai asimetri wajah, palatum tinggi, pergeseran garis median rahang bawah, overjet terbalik, crossbite anterior, geligi berjejal, dan kurva Spee dalam. Pasien dirawat dengan straight wire appliance selama 1 tahun 8 bulan. Breket rahang atas dipasang terlebih dulu sampai overjet terkoreksi. Breket rahang bawah dipasang diikuti reduksi interproksimal. Pasien menggunakan elastik kelas III untuk koreksi relasi kaninus. Reduksi interproksimal menggunakan strip abrasif metal merupakan salah satu cara untuk mendapatkan ruangan pada kasus crowding ringan. Kombinasi reduksi interproksimal gigi anterior rahang bawah dan flaring gigi rahang atas, diikuti penggunaan elastik kelas III efektif mengoreksi overjet terbalik pada kasus maloklusi kelas III. Simpulan: Reduksi interproksimal dan elastik kelas III berhasil mengoreksi kasus maloklusi kelas III disertai crowding ringan dan masalah TSD.Kata kunci: Maloklusi, skeletal kelas III, crowding ringan, tooth size discrepancy (TSD), reduksi interproksimal. ABSTRACTIntroduction: Patient with dentoskeletal class III malocclusion, post-pubertal growth spurt, may be treated with orthodontic camouflage or orthognathic surgery. Camouflage treatment with good prognosis can have acceptable results if there is an only mild skeletal discrepancy. This report was aimed to investigate the effectiveness of camouflage treatment in dentoskeletal class III patient. Case report: A female patient, 16 y.o 7 months, came to Orthodontics Clinic of Universitas Padjadjaran Dental Hospital, complaining her anterior teeth looks crowded and her protrusive mandible. She was diagnosed with dentoskeletal class III malocclusion with asymmetrical face, high palate, midline shifting mandible, reverse overjet, crossbite anterior, crowding, and the deep curve of Spee. The patient was treated with straight wire appliance for one year and eight months. A lower bracket was bonded after anterior crossbite corrected, followed with interproximal reduction. Elastic class III was used to correct canine relationship. Interproximal reduction with metal abrasive is a common practice in orthodontic practice to gain spaces in mild crowding cases. Interproximal reduction in mandibular anterior teeth combined with anterior flaring of maxillary teeth, followed with elastic class III, effectively correct anterior crossbite in class III skeletal patient. Conclusion: Interproximal reduction and elastic class III effective to correct class III malocclusion with mild crowding and tooth size discrepancy problem.Keywords: Maloccusion, dentoskeletal class III, mild crowding, tooth size discrepancy (TSD), interproximal reduction.
