The post is used to retain a core that supports the definitive restoration. One of the important factors in the prognosis of post-endodontic restoration system is the post space preparation design which effects to the distribution of stresses. The purpose of this study was to analyze the effect of post space preparation design at the cervical area of the root to the stress distribution on static loading using (two dimensions) finite element method. This was a numeric simulation study using two 2D digital models: seat and non-seat design of maxillary central incisors using commercial software of finite element. The procedures of pre-processing, solution, and post-processing were used to evaluate the distribution of internal stress caused by static loading 110 N which was applied at 135Â° angle with tooth longitudinal axis on the palatal surface of the core. Both models of restoration with cast post-core of Orden alloy were divided into 15,400 triangular elements. This study showed that the stress distribution from the loading location to the location of stress concentration and the value of maximum stress at cervical part of the root at non-seat design was lower than the seat design (seat design 3.69 times greater than non-seat). This study proved that non-seat design distributes stress better than seat design.

The use of fixed orthodontic appliances can improve someones mastication, speech and appearance. However, this appliance acts as a strange object that may cause irritation to the mucosa epithelial of oral cavity, because of the friction and pressure from the components of the fixed orthodontic appliances which are in direct contact with the oral mucosa. Irritation in the oral mucosa could stimulate the increase of cytokeratin. The appearance of cytokeratin is then used to identify the condition of these cells. This study was a descriptive research to find the expression of cytokeratin 19 with immunohistochemical method in oral mucosa epithelial of fixed orthodontic appliances users. Sample in this study was chosen from 30 fixed orthodontic appliances users. The result of this study was determined by calculating the number of positive cells (brown), compared with total number of cells. The account of positive cells would present the reaction of the epithelial cells according to the inflamation stage which caused by the use of orthodontic appliances. As a conclusion of this study, the use of fixed orthodontic appliances may cause changes in epithelial mucosa which form an adaptation process by increasing the number of progenitor cells marked by cytokeratin 19.

Deoxyribonucleic acid (DNA) is a genetic material which is found in all living organisms. On the human cell or eukaryotes cell, the DNA is found in the nucleus cell and the mitochondria. The DNA arrangement on each cell in human body is the same, that is why, for the analysis meaning, DNA can be isolated from any cell in the body. The source of DNA to be analyzed usually coming from the blood sample by an injection method, such a way resulting in pain and bringing about constraint. Therefore, a study was carried out to look for an alternative of DNA isolation. The aim of this experimental study was to get an optimal DNA isolation method by using oral mucous smear method with a purpose to get a quick and easy DNA isolation. The investigation materials were in the form of samples which were taken from the oral epithelial mucous cells out of three different subjects. The epithelial cells were obtained by the oral mucous smear method which in a variation of two, four and six times of smear applications, respectively. The DNA was then isolated using buffer extraction method. The concentrations of DNA were measured by using ultraviolet spectrophotometer at 260 nm wavelength. The results of DNA isolation were analyzed by Polymerase Chain Reaction (PCR) technique. The optimal DNA isolation could be analyzed by PCR technique. The experimental results show that from three different subjects of study, DNA can be isolated optimally by oral mucous smear method with six times of smear applications.

The one-third lower face height belongs to ideal proportion, ratio 1:1:1, of vertical face height. The one-third lower face height could be influenced by mastication. The one-third lower face height that shorter than normal ratio is generally followed by deep bite which may lead to temporomandibular disfunction even so eustachian tube disfunction, this condition may interfere mastication function, which can be measured by mastication performance. The research objective was to determine the effects of short lower face height to the mastication performance based on overbite. The research method was a cross-sectional study with epidemiology survey type. Research subjects 12-15 years old junior high school with Deutero Melayu Sub races in Bandung. Sampling technique used multistage random sampling by determining the size of the sample based on potluck sample and gained 24 children (group 1) with the normal ratio of vertical face height and 27 children with short lower facial height which were 11 children overbite normal (group 2) and 16 children deep bite (group 3). Mastication performance by 20 times chewing artificial test food then followed by sieving test. Mastication performance value represented by the median particle size (MPS) and the distribution of the particle distribution (b). The results of average MPS and b between group 1, 2 and 3 used statistical analysis MPS with ANOVA test which Fhit=5.56 and pvalue=0.0075, b which Fhit=3.41 and pvalue=0.0430 showed significant differences. Continued with group T test MPS (value = 0.0925) dan b (value = 0.2076) between group 1 and 2 showed a non significant differences. While between group 1 and 3 showed a highly significant differences in MPS (value = 0.0037 and ï¡ = 0,01) and a significant differences in b (value = 0.0141 and ï¡ = 0,05). Conclusions of this study were children with short lower face height and normal overbite did not decrease the mastication performance while children with deep bite decrease the mastication performance.
