Saliva gives a considerable influence against the growth of dental caries as a natural defense against caries. the things very important about saliva are its flow rate and buffering capacity. the decrease in saliva flow rate might cause food retention that furthermore would turn into dental plaques, meanwhile it’s buffering capacity will play a considerable role in maintaining the saliva’s pH and remineralization process of the teeth. One of the mechanisms which are considered to be effective in preventing dental caries is teeth brushing which could change the pH of 5,6 to a normal level. And the right time of teeth brushing will provide an optimal result.The study aims to reveal the influence of teeth brushing time against saliva buffering capacity. The study is an analytic study using a quasi-experimental design. The samples of the study are 20 (twenty) students of dentistry in Health Ministry of Bandung which was purposively selected the sample is divided into 3 groups. The first group is treated by brushing their teeth right after eating bread, the second and third group is treated 15 and 30 minutes after eating bread. The hypothesis uses Kruskal Wallis hypothesis continued by Mann Whitney test, strikethrough. The study reveals that the group brushed their teeth right after eating bread shows low category of saliva buffering is that 55% meanwhile those who brushed their teeth 15 and 30 minutes after eating bread exhibits the result as much as 65% and 25 % Thus the last group is included to those who have a medium risk of suffering from dental carries. The statistics of Kruskal Wallis test within the confidence level of 95% shows that there is an influence of teeth brushing time over the saliva buffering capacity with p<0,001. Mann Whitney test shows that the time of teeth brushing within 15 minutes after eating is better than the group who brush their teeth 30 minutes after eating.

Dental erosion is defined as irreversible loss of dental hard tissue, caused by acid condition in the oral cavity without bacterial involvement. One of the signs of dental erosion is calcium dissolution of the enamel. Yoghurt is a fermented beverage that has low pH level due to lactic acid. The aim of this study was to measure the solubility of calcium enamel after soaking in yoghurt for 12 and 18 hours. Twenty-four premolars were divided into 4 groups. Group A and B were soaked in milk for 12 and 18 hours; group C and D were soaked in yoghurt for 12 and 18 hours. Atomic Absorption Spectrophotometer (AAS) was used to measure the solubility of calcium from each sample. Data were analyzed using one-way ANOVA and LSD (p < 0.05). This study indicated that soaking premolars in yoghurt for 18 hours has greater enamel calcium dissolution than in yoghurt for 12 hours. It can be concluded that prolonged soaking premolars in yoghurt will increase the calcium enamel dissolution.

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  = 0,01) and a significant differences in b (value = 0.0141 and  = 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.

Temporo Mandibular Joint Disorder (TMD) could be caused by forward head posture. Articular sound/TMJ clicking is the most often sign and symptom for TMD that could happen in human being. The presence of TMD such as TMJ clicking would cause an imbalance masticatory system. The purpose of this research is to investigate TMJ clicking effects to masticatory performance. This research was cross-sectional study with a type of epidemiology survey. Subject were children aged 12-15 years old Deutero-Malay sub-races Live in Bandung and was taken using multi-stage random sampling technique. Subject; consisted of 24 children as control group and 28 children as TMJ clicking group. Both group were then checked for masticatory performance using multiple sieve method and 20x chewing of artificial test food. Mastication performance value represented by median particle size (MPS) particle distribution (b) for each group. MPS from TMJ clicking group (3.0571,SD=0.9990) showed higher value than control group (2.28958,SD=0.66838). Statistic analysis with t-test showed that there’s a significant result in both of group (pvalue=0,0024, α = 0,05). Conclussion, temporo mandibular joint clicking subject has lower masticatory performance.

Every human being experiences growth and development, starting from childhood to adulthood. Women who have entered puberty will experience monthly menstrual cycle. One phase of the menstrual cycle is ovulation or the fertile phase of a woman. The fertile period is the period in which there is an egg ready to be fertilized by sperm. At the time of fertility, there is an increase in the amount of estrogen and progesterone hormones. Increase in these hormones is also found in saliva. Saliva as a biological fluid in the body can be used as a diagnostic fluid. Woman’s fertile period can be assessed from the saliva. Saliva containing high estrogen hormones can form a ferning picture on saliva dried on object glass. The type of research is the study of literature. A literature study was conducted to discuss the determining of the fertile woman with saliva ferning test. The results of previous studies showed the existence of differences in saliva pictures at the time of the fertile period and the infertile period. Salivary ferning was very clearly seen in the woman’s fertile period.

Introduction: Orthodontic treatment has a main purpose to reach balanced functional occlusion and create a harmonic esthetic face. But several studies indicates that orthodontic treatment influence smile esthetics, especially smile arc and buccal corridor. One-third of the treated patients showed a flat smile arc and orthodontic treatment with extraction resulted in excessive buccal corridors. The purpose of this research is to evaluate the difference of the Objective Grading System index, developed by the American Board of Orthodontics (ABO) and smile aesthetics in patients with Class I dentoskeletal malocclusion before and after orthodontic treatment. Methods: Twenty dental casts, panoramic radiographs and grouped pre and post-treatment. Dental casts and panoramic radiographs are scored according to the guidelines of the Objective Grading System. Extra-oral photographs were assessed by researcher using modified Goldstein dentofacial analysis. Result of measurements were evaluated with statistical t-test. Results: Results of the research indicates Objective Grading System index and also score of smile esthetics before and after orthodontic treatment shows difference statistically (for Objective Grading System index P = -1121 > 2.09 and for smile esthetics P = 5.15 > 2.09). Conclusions: Extremely weak relationship was found between Objective Grading System index and Aesthetics smiles.

Introduction: Orthodontic treatment could influence alveolar bone height. The longer the treatment, the more effect it will be. The purpose of this study was determined the differences in alveolar bone height at the canine, second bicuspid, mandibular first molar in the case of mandibular premolar extraction with different treatment duration. Methods: This study is a retrospective – comparative analytic study, involving 17 samples which have finished orthodontic treatment at FKG Unpad PPDGS orthodontic clinic. The alveolar bone height was determined from panoramic x-rays obtained by measuring the ratio of alveolar crest and the cemento enamel junction to the tooth cusp (Bjorn method). The results of the study were then analyzed using t-student test with Pvalue=0.05. Results: The results showed a significant correlation in alveolar bone height reduction. In the group less than 2-years treatment, there was a reduction in alveolar bone height only at the mesial side of tooth 35 while there was a significant reduction at the distal canine, the mesial-distal second bicuspid and the mesial-distal side of the mandibular first molar in a group more than 2 years-treatment. Conclusions: This study concluded that there was a significant influence on the duration of treatment and alveolar bone height reduction in the group more than 2-years treatment.

Objective methods of determining the vertical dimension of occlusion (VDO) offer significant advantages because no radiographs or others special measuring devices are required. One of the objective measurement of vertical dimension of occusion is twice the intercanthal distance (ICD). The purpose of this study was to compare whether there was a difference between the length of VDO and the length of twice the ICD among Mongoloid race, which was represented by eighty students, chosen randomly from undergraduate students of Faculty of Dentistry Universitas Padjadjaran that fulfilled all criteria stated. Result showed that there was no difference between the length of VDO and twice the ICD in this population. Thus, in this study, the ICD can be suggested as a method to determine the VDO in this population.
