Microscrew implant is a new alternative of an orthodontic anchoring device which is planted by simple surgery procedure into soft tissue and mandibular bone to utilize mandibular bone as an intraoral anchoring source. Microscrew implant is a small screw and consists of four components that can give various advantages, made from a titanium material, and developed in various sizes and designs. Microscrew implant is strong, stable, and effective to be used as an absolute anchoring device in orthodontic treatment without losing the anchoring.

Introduction: Third molar impaction has been a controversial topic among clinician when it comes to mandibular anterior teeth crowding. The aim is to know the prevalence of third molar impaction in patient with mandibular anterior teeth crowding in Orthodontic Department, RSGM UNPAD, Indonesia. Methods: This was a descriptive research, with non-probability sampling obtained from a population with full arch 32 teeth. Totaling 54 samples from year 2011 to 2014 were obtained. The age of sample range from 15 to 25 years old. Also all panoramic radiographs taken from the year 2011 to 2014 were examined using a computer. The position of third molars were determined by Winterâs classification using angle formed between the intersected longitudinal axes of the second and third molars and anterior teeth status by using Littleâs irregularities index. Results: This study obtained data that as much as 68.52% mesioangular third molar, 19.44% distoangular, 4.63% horizontal, 1.85% buccolingual and 0% others. In mesioangular impaction condition there was crowding 83.78%, in distoangular condition there was 100% crowding, in horizontal position crowding found 100%, while at buccolingual crowding found 100%.Conclusion: In all positions the third molar impaction was accompanied by crowding of the mandible anterior teeth, with the largest percentage of impaction was the mesioangular position

The aims of this study were to introduce fixed symmetrograph as a device to analyze arch symmetry and to compare the result of arch symmetry measurements using such appliance with commonly used symmetrograph in Faculty of Dentistry Padjadjaran Universitas (Orthocross). Twenty based study models used in this study. The method used in this study was by comparing the result of measurement using orthocross with the result of measurements using fixed symmetrograph. The result of this study revealed there was no significant difference between measurement using orthocross with measurement using fixed symmetrograph (P>0,05). Based on the result of this study, it is recommended to use this fixed symmetrograph, because there were several advantages using this device, for example, symmetrographâs midlines superimpose exactly with study modelâs midlines with the aid of two vertical pins. Even more, the study model can be fixated using two fixators so that the study model and fixed symmetrograph were not moving during measurement.

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 ISO-certified bracket has a smoother base surface than the non-ISO-certified bracket base.Keywords: Surface roughness, stainless steel slot bracket, atomic force microscope

Introduction: The soft tissue aspect in orthodontics treatment has gained attention in the last few years. The soft tissue profile is said to reflect the underlying skeletal profile, which causes a convex profile in patients with class II skeletal malocclusion. This research was aimed to determine the changes in the soft tissue facial profile of class II skeletal malocclusion patients with retrognathic mandible after twin block treatment. Methods: The type of research used in this study was retrospective descriptive research with paired t-test. The population was children aged 10-13 years old with class II skeletal malocclusion that were treated with twin block appliance in the Faculty of Dentistry Universitas Padjadjaran, Indonesia. The results of soft tissue changes before and after twin block treatment were compared. Results: There was an insignificant increase in soft tissue profile angle and Holdaway’s soft tissue angle after twin block treatment (p > 0.05). Whereas, Holdaway’s H-angle was decreasing and Merrifield’s Z-angle was increasing after twin block treatment, with statistically significant difference (p < 0.05). Conclusion: There was a decrease of H-angle, indicates a reduction in facial convexity and improvement of the facial profile after twin block treatment, but no difference in soft tissue profile angle and Holdaway’s soft tissue angle after twin block treatment. Keywords: Facial soft tissue profile, class II skeletal malocclusion, retrognathic mandible, twin block appliance

Introduction: The IRF6 rs2235373 (C/T) is a polymorphism in the intron region that has been associated with non-syndromic cleft lip and palate (NS CLP) among some populations. Polymorphism in introns can also affect the transcription that should be detected through some changes in IRF6 mRNA expression. This study was aimed to evaluate the effects of IRF6 rs2235373 polymorphism on mRNA expression changes in NS CLP with its phenotypes which include complete unilateral (CU) CLP, complete bilateral (CB) CLP, cleft lip only (CLO), and cleft palate only (CPO). Methods: This study was a laboratory analytical study, using samples from 198 individuals in Indonesia (136 individuals with NS CL/P consisted of CU CLP (n=42), CB CLP (n=34), CLO (n=33), CPO (n=27), and 62 individuals as controls). DNA was extracted from venous blood, and the segment of rs2235373 was evaluated by PCR and Sanger sequencing. mRNA expressions analysis preceded by RNA extraction from oral epithelium, then real-time (RT) PCR was performed. mRNA expression changes were analysed by Livak method and Kruskal Wallis test followed by the Mann Whitney test through CC, GT, and TT genotype. Result: The mRNA expression of TT genotype from NS CU CLP and control was 3.36 higher value than CC genotype (p=0.008), and the mRNA expression of CT genotype from NS CB CLP and control was 0.16 lower value than CC genotype (p=0.000). Conclusion: The IRF6 rs2235373 polymorphism of TT genotype tend to cause mRNA overexpression in NS CU CLP, and CT genotype tend to cause mRNA underexpression in NS CB CLP.Keywords: Non-syndromic cleft lip and palate, NS CLP phenotype, IRF6, rs2235373, mRNA expression.
