ABSTRAKPenentuan dimensi vertikal oklusi (DVO) yang tepat merupakan salah satu faktor penting yang perlu diperhatikan dokter gigi dalam prosedur klinis perawatan gigi. DVO adalah jarak antara dua titik anatomi yang dipilih, yaitu satu titik pada maksila dan satu titik pada mandibula ketika posisi oklusi sentrik. Beberapa metode dianjurkan dalam pengukuran DVO. Salah satu metode penentuan DVO yang dikembangkan oleh para ahli yaitu metode antropometri. Metode ini dilakukan dengan cara pengukuran panjang jari kelingking. DVO dan panjang jari kelingking berbeda pada setiap ras manusia karena masing-masing ras memiliki ciri-ciri spesi k yang berbeda antara satu dengan yang lain. Sub ras Deutro Melayu merupakan salah satu sub ras di Indonesia. Penelitian ini bertujuan untuk mengetahui korelasi antara hasil pengukuran DVO dan panjang jari kelingking pada sub ras Deutro Melayu di Kota Padang. Penelitian ini merupakan penelitian observasional analitik dengan pendekatan cross sectional. Sampel sebanyak 112 warga Kota Padang yang merupakan sub ras Deutro Melayu dan memenuhi kriteria, terdiri dari 56 orang laki-laki dan 56 orang perempuan. Data diuji secara statistik dengan analisis Pearson correlation. Terdapat korelasi yang bermakna antara hasil pengukuran DVO dengan panjang jari kelingking dengan nilai r=0,768 dan hasil kedua pengukuran ini menunjukkan nilai yang hampir sama dengan nilai p=0,000, sehingga signi kan secara statistik (p<0,05). Pengukuran antropometri panjang jari kelingking merupakan metode yang dapat digunakan untuk menentukan DVO. Kata kunci: dimensi vertikal oklusi, jari kelingking, sub ras Deutro Melayu ABSTRACT: Correlation between VDO with length of little nger in Malay Deutro sub race. The correct determination of vertical dimension of occlusion (VDO) is an important step to to concern for dentist in clinical procedures
Background : Alginat is one of the most used impression material in dentistry.. Alginate impression need to be disinfected to prevent cross-infection. One of effective natural material that can be used as disinfectant is avocado leaves. The process of disinfection could interfered the dimensional stability of alginate impression caused of imbibition properties in alginate itself. Purpose : To determine the differences of dimensional stability of alginate impression which disinfected with avocado leave extract 100% compared 0.5% sodium hypochlorite. Method : This research was an experimental laboratory with post -test only control group design. Sample were divided into 3 groups, 1 group were sprayed with aquadest as control group and 2 treatment groups were sprayed with avocado leaves extract 100% and 0.5% sodium hypochlorite and stored for 10 minutes. The impression then casted with gypsum in cylinder mold and diameter of the cast were measured. The One Way ANOVA test were used to determine the dimensional stability of the difference between the groups. Result :The results showed that the alginate impression which disinfected with avocado leaves extract 100% have a significant dimensional change, that is 0.123 ± 0.011 mm compared with 0.5% sodium hypochlorite only 0.034 ± 0.011 mm. Conclution : There are differences in dimensional stability of alginate impression which disinfected with avocado leaf extract 100% and 0.5% sodium hypochlorite. Keywords:Dimensional stability, avocado leaves extract, and sodium hypochlorite
Stress is known as a risk factor for temporomandibular disorder. Prisoners who live in Correctional Institutions have a high risk of experiencing stress because of the existing pressure. The purpose of this study was to determine the relationship between stress and temporomandibular disorder in prisoners at Class IIB Correctional Institutions in Padang. This study was a cross-sectional study. The instrument that use to measured stress on inmates was the Perceived Stress Scale 10 (PSS-10), while to determine the diagnosis of TMD using RDC/TMD Axis I. The result showed that 7 respondents (23,3%) had mild stress, 20 respondents (66,7%) had moderate stress, and 3 respondents (10%) had severe stress. Respondents who experienced TMD were 19 respondents (63,3%). The most common type of TMD diagnosis is the disc displacement with reduction. Kolmogorov-Smirnov statistical test results obtained p=0,164 (p>0,05) which means there is no significant relationship between stress and temporomandibular disorder in prisoners at Class IIB Women’s Penitentiary in Padang. This study concludes that stress is not related to the temporomandibular disorder in prisoners at Class IIB Women’s Penitentiary in Padang.
Introduction: Heat-polymerized acrylic resin is the most basic denture material used. One of the mechanical properties of an acrylic resin is its transverse strength. The transverse strength test provides an overview of the material's durability in accepting the load at mastication. Consumption of tea, especially black tea in the world placed the second most consumed. The purpose of this study was to determine the effect of black tea on the transverse strength of heat-polymerized acrylic resin. Methods: This research was an experimental laboratory with 24 samples of heat-polymerized acrylic resin plate with the size of 65x10x2.5 mm. The sample was divided into 6 groups, each consisted of 4 samples. The first, second, and the third groups were immersed in aquadest for consecutively 1, 4, and 20 days. The fourth, fifth, and sixth groups were immersed in the black tea for consecutively 1, 4, and 20 days. The transverse strength was tested using the three-point bending method with the Universal Testing Machine. The results of the transverse strength measurement were then analyzed statistically by the One-way ANOVA test and Holm's sequential Bonferroni posthoc test as an advanced test. Results: The results of the statistical test showed that p<0.05 (p=0.000) which means that the six groups have a significant difference in the average value of the transverse strength. Conclusion: The conclusion of this research was the black tea immersion duration was affecting the transverse strength differences of the heatpolymerized acrylic resin.
Porcelain fused to metal (PFM) bridge is the most of treatment that commonly used as a fixed partial dentures. One of the indication for PFM bridge is to replacing the loss of posterior teeth. This case report discussed about the treatment of posterior missing teeth with PFM bridge. Objective: to explain the clinical procedures of PFM bridges to treat the patient with posterior missing teeth. Case report: A 29-years old woman came to prosthodontic clinic in Faculty of Dentistry University of Padjadjaran with chief complaint of right maxillary posterior missing teeth. The treatment planning that have been choosen for this case was the porcelain fused to metal bridge due this excellent characteristic of resistence to mastication force compared with other types of bridge such as all ceramic or all acrylic bridge. Beside that, the aesthetic achievement of this kind of bridges is more excellent than all metal bridges. Disscussion: A spatial analysis, calculation the number of abutment against which used, and selected design bridge very determine the success of this treatment. In addition to that, the clinical procedures consisting of abutment teeth preparation, an accurate impression, and appropriate cementation were needed to get the satisfactory result. Conclusions: The porcelain fused to metal bridge is a appropriate option for posterior missing teeth treatment that fullfil satisfactorical biomechanical and esthetic factors.
