Abstract

Treatment of Class II malocclusion have impact in relation to the vertical dimensions of the skeletal and facial soft tissues mainly to the facial balancing and proportion which relate to patient facial harmony. The aim of this study was to determine the changes and differences in facial vertical dimensions to the total value of facial harmony in skeletal Class II after treatment with extraction and non-extraction of the maxillary first premolar based on Arnett and Bergmann at the Orthodontic Specialist Clinic of RSGM, Universitas Sumatera Utara. The sample consisted of initial and final cephalometry of 36 patients with age 18-35 years old, skeletal Class II malocclusion ANB > 4o, divided into extraction of maxillary first premolar and non-extraction group. Cephalometric tracing with the required points, then the photos are processed into image J software. Then the data that obtained is tested statistically with Pearson’s Correlation Test and T-Test Independent. There was a significant change between MP-SN and Pog-Imd (P=0,036) in the first premolar extraction group, but there was not a significant change in the non-extraction first premolar group. There was a significant difference in the face harmony value at point G-A between the extraction and non-extraction groups (P=0,038). There was a significant difference on the face harmony value in the treatment of malocclusion Class II orthodontic with maxillary first premolar extraction.

Abstract

Closed coil spring is an additional tool in a fixed-orthodontic treatment. NiTi is an orthodontic alloy that has shape memory and elasticity features, while stainless steel has properties of malleability, low friction between wire-bracket, as well as easy soldering and welding. Various properties of closed coil springs have been widely studied, but research on the stretching time remains unclear. This study aimed to determine the effect and differences in the stretching time for 7 days, 14 days, 21 days, and 28 days on the force magnitude of NiTi and stainless-steel (SS) closed coil spring. A 7 x 5 x 1 cm acrylic blocks with 1 cm acrylic posts were employed, and 25 mm closed coil springs were attached to the acrylic posts using modified T-sticks. The springs were immersed in an artificial saliva with pH of 6.75 for 7, 14, 21, and 28 days in an incubator at 37 °C. The container was removed from the incubator and the force was measured using a universal testing machine. Kolmogorov-Smirnoff test was carried out to analyze parametricdata, while independent T-test was used to determine the difference between each group. There was a significant effect of stretching time on the force magnitude of the SS closed coil spring in all the groups (p < 0.05). There was no significant effect of stretching time on the force of the NiTi closed coil spring on days 7, 14, and 21 (p > 0.05) but there was a significant effect on day 28 (p < 0.05). A significant effect between the ratio of the SS and NiTi closed coil spring (p < 0.05) was confirmed. Longer stretching time indicated a force loss in the SS closed-coil spring, while the NiTi spring had a more stable force which implies a formidable treatment-time for orthodontic treatment.

Abstract

Batik berarti bertitik atau membatik membuat bertitik. Membatik bertujuan untuk menciptakan lingkungan hidup yang indah. Batik sebagai budaya bangsa perlu dikenalkan dan dilesarikan kepada generasi muda di Indonesia, termasuk di kalangan anak muda. Generasi muda merupakan pilar penting dalam usaha pelestarian batik di era globalisasi dan era digial ini. Kegiatan pengenalan dan pelatihan batik terhadap siswa siswi sekolah ini sangat bermanfaat. Selain menumbuhkan kreativias juga meningkatkan kebudayaan lokal indonesia  Para peserta didik yang menjadi peserta pengenalan dan pelatihan batik sangat antusias dan mengikuti kegiatan dengan semangat. Para remaja juga mendapat pengetahuan mengenai sejarah dan ciri khas batik tulis,cara pembuatan dan juga bahan bahan yang dipakai Para peserta juga telah mampu menciptakan batik tulis dengan kreaifitas masing masing.
