Model study is one of the standard orthodontic components which is important for diagnosis and treatment plan, but in some patients with the high gag reflex, it will be difficult to get this kind of study models. The existence of a new device which is able to show the condition of patients mouth in three space areas (axial, sagittal, and coronal) is expected to be an alternative when a study model is difficult to get. The purpose of this study is to find out whether or not there are any differences on the size of canines mesiodistal, first and second premolar resulted from CBCT imaging with Moyers analysis on the study models. The method of the research is comparative descriptive. Measurements are made on 10 CBCT imaging results and 10 study models. The mesiodistal size, the result of CBCT imaging is measured by the available computer program and also the mesiodistal size of the study models is measured using a sliding compass, and then the size of canines, first and second premolar teeth resulted from CBCT imaging are compared to the result of Moyers method analysis on the study models. The t-test is used to find out if there is a difference between teeth size value between the CBCT imaging with the study models. The significance is determined based on the p-value < 0,05. The statistical test result shows a significant difference between the size of canines mesiodistal, first and second premolar teeth, the result of CBCT imaging and the Moyers analysis result in the study models in which t count > t table.

Polimerizatian is the critical stage to determine the quality of composites resin, this involves isolated monomer carbon double bonds being converted to an extended network of single bonds. Physical and mechanical properties of composites are influenced by the level of conversion attained during polymerization. An adequate light intensity and light curing time are important to obtain the degree of polymerization. The objective of this study is to evaluate the difference of the hardness nanocomposites which activated by LED LCU based on the variation of curing times. This study is a true experimental research. The samples were made from nanocomposites material with cylinder form of 4 mm in depth, 6 mm in diameter. This samples divided into 3 groups of curing times. Group, I was cured for 20s curing time as a control due to manufactory recommended; Group II was cured for 30s, and Group III was cured for 40s and the hardness (Rebound hardness tester) was determined using Rebound scale (RS) and converted by Mohs scale (MS). There was a very significant level of hardness rate from each group using ANOVA test. The result of the study concludes that there were the differences on the nanocomposites hardness level cured under different curing times 20, 30 and 40 sec. The longer of curing times, the higher level of hardness.

The purpose of this study was to examine the stability of orthodontic treatment results in dentoskeletal class I malocclusion treated with and without extraction of four premolars and to compare the stability of treatment result between those groups. Occlusal relationship after treatment and six-month post retention were measured on dental cast using The Objective Grading System Index at Orthodontic Specialist Clinic, Faculty of Dentistry Universitas Padjadjaran. The analytic descriptive study was carried out on 30 samples that comprised 14 samples were treated without extraction of four premolars and 16 samples were treated with extraction of four premolars. ABO Measuring Gauge was used to measure seven variables: tooth alignment, the height of the marginal ridges, buccolingual inclination, occlusal relationships, occlusal contacts, overjet, and interproximal tooth contacts. The results were statistically analyzed with the Wilcoxon rank test to test the difference of The Objective Grading System Index between posttreatment and postretension. Mann-Whitney U test was applied to determine the difference between the group with the extraction of four premolars and the group without extraction of four premolars. The level of significance was set at 0.05. The results of this study showed these following variables: tooth alignment, occlusal contacts, and overjet were unstable at the group with the extraction of four premolars, while only tooth alignment was found to be unstable in the group without extraction of the four premolars. Mann-Whitney U test did not show statistically significant difference in stability comparison test between the groups.

Dentist has long been recognized as a formal health profession. Health professionals have an important role to play in the fight against tobacco. Smoking tobacco is dangerous because it related disease and also due to it being labeled as a gateway to illicit drug abuse. As individuals, the dentist can help educate the population, as community members they can support anti-smoking policies and at a societal level, they can influence national and global tobacco control efforts. The associations between tobacco use and diseases affecting the oral cavity, such as periodontal disease and cancer, are now well recognized. This has lead to proposals from some members of the profession that members of the dental team should provide smoking cessation services. Before exploring effective ways to help smokers quit, it is important to understand the nature of the addictive process and how it affects both nicotine use and cessation attempts. The potential influence of dentists as agents of change is clear from even a brief consideration of the nature and conditions of the dentist-patient relationship. The dental practice setting provides a unique opportunity to assist tobacco users in achieving tobacco abstinence. The role of psychiatrists to support the effort, therefore, becomes all the more important.

Invasion is a characteristic of the occurrence of cancer and indicates the cancer cells capability to destroy and degrade the border between the epithet and basal membrane to further spread into the surrounding extra-cellular matrix. The purpose of this research was to find the existence of impediment at the SP-C1 tongue cancer cell using celecoxib chemopreventive medication. The SP-C1 tongue cancer cells were treated in vitro using celecoxib medication as a research subject at the following concentrations 5, 10, 25, 50, 75, 100, 125%; and 0 as control group (only DMEM growth medium treatment). Pure experimental testing was carried out for 24 and 48 hours, with observation and calculation of an average number of SP-C1 tongue cancer cells. The data collected were analyzed using the ANOVA test with Newman Keuls paired range test or t-test. Research results indicated that the average number of SP-C1 tongue cancer cells invasion after administration of celecoxib medication based on administration concentration and time statistically yielded significant results. The ANOVA test results were statistically significant, that is, average occurrence of the number of SP-C1 tongue cancer cells due to the use of celecoxib at certain concentrations compared to that without celecoxib was different. At celecoxib of zero (control) concentration was 24.4 with celecoxib concentration starting at 5 up to 125% experienced a decline from its average 11 to become 2.3. The conclusion of the research was that the greater the celecoxib concentration administered, the greater the effect on the impediment of SP-C1 tongue cancer cell invasion.

Odontectomy should be performed aseptically. The goal of sterilization is the complete killing of all forms of microbial life including bacterial spores on the items being processed. Biologic monitoring provides the main guarantee of sterilization. The aim of this study was to find the interrelation of the temperature and the holding time of instrument sterilization as an infection control for the successful of lower molars odontectomy. This experimental laboratory study was conducted at the Oral Maxillofacial Surgery Department in the Hasan Sadikin General Hospital Bandung and at the Microbiology Laboratory Faculty of Dentistry, Universitas Padjadjaran, Jatinangor. The Protocol was performed in three methods of sterilization: dry heat with oven and ozone, dry heat with oven and infrared (125)C for 15 minutes), both were monitored by Bacillus atrophaeus as the biologic indicators, and autoclavization (121" C for 15 minutes) with Geobaciflus stearothermophilus as the biological monitoring, with 17 times repetition. After sterilization, all of the indicators were cultured on Nutrient Agar Plate (NAPS), and the subsequent growth was assessed. The colony forming units (CFUs) were counted by Stuart Electric Bacteria Colony Counter. Adequate positive and negative controls were used in every cycle. The results showed that after autoclavization, all spores were killed. In comparison with dry heat in the oven, there were still CFUs on the NAPs, but no colonies grow after 3 repetitions by oven and infrared. Heating in oven and ozone could only reduce the spore numbers, even after repeating 5 times. The reduction of the CFUs was greater in more repetition. According to the statistical analysis, the differences were significant. This study concluded that sterilization by oven and infrared will be achieved after 3 holding times (30-35 minutes) and dry heat with oven and ozone could only act as a germicide. In autoclavization, all of Geobacillus steorothermophilus have been killed.

Propolis is a resinous material collected by honey bees from various plants. Many types of research have shown that it has antibacterial and anti-inflammation activities. Flavonoid is the main chemical substance in propolis that inhibits bacterial growth and reduces the release of free radicals, suggesting that this component has anti-bacterial and anti-inflammatory properties. However, there is another chemical substance in propolis that shows antibacterial dan anti-inflammatory activities. The purpose of the present study was to assess the rat dental pulp tissue reaction after capped with propolis derived non-flavonoids extract. Non-flavonoids substances were purified from an ethanol extract of propolis obtained from South Sulawesi, Indonesia. A Class I cavity was prepared on the occlusal surface of the right maxillary first molar in Spraque-Dawley rats. The dental pulp was exposed and then capped with a zinc oxide-based filler as a control (Group I), or non-flavonoids propolis (Group II). Then, each cavity was filled with glass ionomer cement. The animals were sacrificed at week 1, 2, or 4. Biopsy samples were obtained, and these were stained and viewed by light microscopy. The histological examination was based on the presence of polymorph nuclear leukocytes and macrophages. The results showed that pulp inflammation occurred in both groups as early as week 1. However, the inflammation occurred in Group II was relatively milder compared to Group I at all time period. Therefore, present results suggest that application of non-flavonoids propolis extract on rats dental pulp tissue might inhibit inflammatory process.

The Thumb Rule of Leonardo da Vinci states that many proportions of the face show relationship with the length of thumb which is measured from the proximal tip of the proximal phalanx to the distal tip of the distal phalanx. Previous studies have shown that the length of the vertical dimension of occlusion (VDO) is similar to the length of thumb of the Caucasoid race. The purpose of this study is to determine whether the length of VDO have correlations with the length of thumb among those of the Mongoloid race. This study took a survey method with the analytical cross-sectional approach. A total of 80 students of Faculty of Dentistry who have fulfilled all population criteria were randomly chosen to measure the length of VDO and the length of the thumb. Results analyzed with Students t-test statistic revealed that there was a significant difference between males and females in the length of VDO and the length of the thumb, however, there was no significant difference between the length of VDO and the length of the thumb. There were very strong correlations (P<0.05) between the length of VDO and the length of the thumb. As a conclusion, the length of thumb can be suggested as an objective method to determine the length of VDO in this population.
