Introduction: The primary second molar relation is also called the terminal plane, which is the relation between the distal surface of the maxillary and mandibular second primary molars in a centric occlusion position. One of the most important characteristics of the ideal occlusion development on the primary dentition is if the primary second molar relation classified as the flush terminal plane. This relation plays a significant role in determining the relation in permanent molar because the eruption of the first permanent molars are guided by the distal surface of the maxillary and mandibular second primary molars. The purpose of this study was to found out the clinical description of the primary second molar relation among the preschool-aged children in four kindergartens in Banda Aceh. Methods: This study was a descriptive study with cross-sectional study approach. The subject selection method was performed with a purposive sampling method involving as much as 37 subjects, which wereÂ studentsÂ of State Kindergarten of Pembina 1, State Kindergarten 2, State Kindergarten 3, and State Kindergarten of Adidarma 4, Banda Aceh. The examination was performed by using the intraoral mirror when the teeth were in the centric occlusion position. Decisions regarding the primary second molar relation were made by the bilateral occlusion (left and right). Results: The flush terminal plane was found in 45.9% of all respondents, the mesial step was 54.1%, and the distal step was 0.0%. Conclusion: The primary second molar relation among preschool-aged children generally had the mesial step.

Introduction: Tooth restoration and implant-supported was one of the methods to overcome the free end cases. Abutment and implant are two components that are fused together by a screw. Therefore, the main problem to solve are loosened screw and implant or abutment fracture because of increasing unpredictable potential force on the implant, abutment, and screw. The purpose of this research was to describe the distribution stress between the connection of the body of implant and abutment on the submerged and non-submerged design of the implant supported bridge. Method: The submerged and non-submerged design implant have been analyzed using the Finite Element Method under lateral and vertical static load for 180 N. The numeric model for lower jaw posterior segmented bone was determined by computed tomography, and the load measurement was performed to observe the distribution at the connection between the body of implant and the abutment of the implant supported bridge submerge and non-submerged design. Results: At the lateral load, the distribution strength value was 1.562x107 Pa, whilst for the non-submerged was 9.63x107Pa. At the vertical load, the distribution strength value was 1.038x107 Pa, whilst for the non-submerged was 3.342x107Pa. At the load of 180 N towards the vertical and lateral on the supported implant bridge, the distribution strength value had a smaller scale compared to the ultimate tensile strength (UTS), which was 1040 MPa (1.04 x 109 Pa). Conclusion: Both of the design including the secondary component (abutment) was safe to used as the supporting implant bridge.

Introduction: Tooth discolouration is the most common esthetic problems in dentistry. Direct composite veneer is an adjunctive therapy for severe teeth discolouration by attaching to the tooth surface using an acid etching and dental bonding agent. In several cases of severe discolouration, it is required to have certain preliminary treatments such as bleaching prior to the placement of the composite veneer. However, bleaching agents are able to lead the enamels morphology and microstructure alteration by inhibiting the polymerisation bonding thus affecting the veneer adhesion. This study was aimed to determine the tensile bond strength of direct composite veneers between the V and VII generation dentin bonding agent after extracoronal bleaching. Methods: This study was an experimental laboratory of as much as 32 human permanent maxillary central incisors were divided into 4 groups. Group 1 was treated with extracoronal bleaching and bonded with the V generation bonding nanohybrid composite. Group 2 was treated with extracoronal bleaching and bonded with the VIII generation bonding nanohybrid composite. Group 3 was only bonded with the V generation bonding nanohybrid composite. Group 4 was only bonded with the VIII generation bonding nanohybrid composite. All samples were immersed in artificial saliva then incubated at the room temperature for 24 hours. Results: The tensile strength value was determined using the Universal Testing Machine. The ANOVA test results showed significant differences in all four groups (p < 0.05). Conclusion: The VIII generation bonding agent had a higher tensile strength than the V generation.

Introduction: Salvadora persica, also known as miswak (Kayu sugi), has been used as natural toothbrushing compound for centuries. Many research suggested that it contains medically beneficial properties such as abrasives, antiseptics, astringent, detergent, enzyme inhibitors, and fluoride. The objective of this study was to assess the efficacy of miswak containing toothpaste on dental plaque accumulation. Methods: The total of 30 subjects consisted of male students of Bandung Institute of Technology, aged between 18 â 26 years old. The plaque value was measured using the Turesky Gilmore & Glickman Index Modification of Quigley & Hein at baseline (day 0), day 1, day 3, and day 7. Commercial toothpaste (PepsodentÂ®) was used as the control group in this pre and post-test designed, single-blind study. Results: After analysed using the paired t-test, the data showed that the mean plaque index of respondents using miswak and non-miswak containing toothpaste from baseline until day 7, were 1.70/1.19 and 1.61/1.44 respectively (p < 0.05). The mean plaque index reduction of respondents using miswak and non-miswak containing toothpaste from baseline until day 7, were 0.39 and 0.25 respectively (p = 0.00). Conclusion: Both kinds of toothpaste were able to reduce plaque, but miswak containing toothpaste was found to be more effective in reducing dental plaque accumulation.

Introduction: Sapphire bracket is the best aesthetic bracket with metal bracket-like mechanical properties. In conditions causing attachment lost between sapphire bracket and enamel, a rebonding procedure will needed. The shear bond strength of sapphire bracket decrease after the rebonding procedure. Sandblasting, hydrofluoric acid etching, and silanization as surface treatment are widely used to improve the bracket bond strength. The purpose of this study was to evaluate the effect of zirconia as sandblasting material towards the shear bond strength of reconditioned sapphire bracket. Methods: This study was an experimental laboratory with as much as 27 samples of sapphire bracket divided into 3 groups. Group I was rebonded with sandblasting zirconia and silane, group II with hydrofluoric acid etching and silane, and group III with new bracket bonding. The attachment strength measurement indicator was the shear bond strength test and the SEM analysis. Results: The shear bond strength test showed the average value for each group were 12.97 MPa, 9.26 MPa, and 10.58 MPa, consecutively. The test results were then analysed using a one way ANOVA and LSD (p < 0.05), which showed that significant difference only found in the comparison between group I with group II, but not in the comparison between group I with group III. The SEM analysis result showed that sandblasted surface has homogenous microporosities in high quantities. Conclusion: Zirconia as sandblasting material was effective in increasing the shear bond strength of reconditioned sapphire bracket.
