Objective: To assess oral cancer awareness, its associated factors and related sources of information among a selected group of Malaysians. Methods: A cross-sectional survey was conducted on all Malaysian ethnic groups aged ${\geq}15$ years old at eight strategically chosen shopping malls within a two week time period. Data were analysed using chi-square tests and multiple logistic regression. Significance level was set at ${\alpha}$ <0.05. Results: Most (84.2%) respondents had heard of oral cancer. Smoking was the most (92.4%) recognized high risk habit. Similar levels of awareness were seen for unhealed ulcers (57.3%) and red/white patches (58.0%) as signs of oral cancer. Age, gender, ethnicity, marital status, education, occupation and income were significantly associated with oral cancer awareness (p<0.05). Conclusions: There was a general lack of awareness regarding the risk habits, early signs and symptoms, and the benefits of detecting this disease at an early stage. Mass media and health campaigns were the main sources of information about oral cancer. In our Malaysian population, gender and age were significantly associated with the awareness of early signs and symptoms and prevention of oral cancer, respectively.

본 연구에서는 최근 Sato 등이 고안한 mixing ability index(MAI)를 이용하여 측두하악장애 환자 중 통증이 있는 군과 무통성 관절잡음이 있는 군을 대상으로 객관적인 저작 효율을 정상인으로 구성된 대조군과 비교하고, 주관적인 평가 방법인 설문조사법 중에서 음식섭취가능지수(Food Intake Ability Index, FIA)와 저작 능력에 대한 주관적 인식도 평가(Visual Analogue Scale, VAS)를 이용하여 저작 효율을 평가하고, 구강건강과 관련된 삶의 질을 평가하기 위해 Oral Health Impact Profile(OHIP)-49K 설문조사를 시행하였다. 각 평가 방법 간의 상관성을 알아보고, 또한 통증군에 있어서는 치료 후 통증이 감소함에 따라 저작 효율의 변화 양상을 조사하여 다음과 같은 결과를 얻었다. 1. MAI, FIA, VAS는 통증군이 정상군에 비해 통계학적으로 유의하게 감소하였으며, 관절잡음군보다도 감소하여 통증군이 정상군과 관절잡음군에 비해 저작 효율이 떨어지는 것으로 나타났다(P<0.05). 관절잡음군에서는 MAI, FIA, VAS에서 정상군과 유의한 차이를 보이지 않았다. 2. 구강건강관련 삶의 질에 대한 설문지인 OHIP-49K의 경우 정상군에 비해 통증군과 관절잡음군 모두 통계학적으로 유의하게 증가하여 구강건강과 관련한 삶의 질이 떨어지는 것으로 나타났다. 3. 전체 대상자(71명)에서 객관적 저작 능력 평가 방법인 MAI와 주관적 저작 능력 평가 방법인 FIA와 VAS간에는 서로 유의성 있는 상관관계를 보였다(P<0.01). OHIP-49K에서도 MAI를 제외하고 모두 통계학적으로 상관관계가 있는 것으로 나타났다. 4. 관절잡음군에서는 FIA와 VAS에서만 통계학적으로 상관관계가 있는 것으로 나타났으며(P<0.01), 이외의 모든 항목은 상관관계가 없는 것으로 나타났다. 5. 각 평가 방법 간의 상관성에서 FIA와 VAS는 전체 대상자, 통증군, 관절잡음군 모두에서 상관관계가 있는 것으로 나타났다. 6. 통증군에서 치료 전에 비해 치료 후 통증 감소와 함께 VAS에서는 통계학적으로 유의성 있게 증가 하였다(P<0.05). 반면에 MAI에 있어서는 저작 효율이 증가하는 경향을 보였으나 통계학적 유의성은 없었다. 또한 FIA, OHIP-49K에서도 치료 전과 후 통증 감소에 따른 변화는 없는 것으로 나타났다. 이번 연구를 통하여 측두하악장애 환자에서 저작 효율을 감소시키는 주요인은 통증이며, 관절잡음은 저작 효율을 감소시키는 요인은 아니지만 삶의 질을 저하시키는 한 요인으로 작용한다는 것을 알 수 있었다. 따라서 측두하악장애 환자에서 저작 효율을 개선시키기 위해서는 우선적으로 통증을 치료하는 것이 가장 중요하며, 삶의 질을 향상시키기 위해서는 통증뿐만 아니라 관절잡음에 대한 관리도 필요할 것으로 사료된다.

Purpose: This study was performed to evaluate the effect of powered toothbrush with a wireless remote display on the subjective and objective oral hygiene improvement. Methods: One hundred and fifteen subjects in healthy or mild gingivitis status between the ages of 20 and 90 were recruited and reviewed for study inclusion criteria. At first visit, 115 pre-screened subjects filled in the questionnaire form which consisted of demographic factors, behavioral factors (smoking, alcohol consumption), toothbrushing habits (brushing time and frequency), self-reported oral health status, and self-satisfaction. Baseline clinical indices (Plaque index, Gingival index) were also recorded by a periodontist. Subjects were instructed how to use powered toothbrush with a wireless remote display, and were provided with it. Thirty days after first visit, 90 subjects returned for the second assessment by self-reported questionnaire form and professional clinical checkup. Statistical analysis was performed using paired t-test for the difference between baseline and second visit data. The relationship among variables was examined with chi-square test and Fisher' s exact test. Results: Significant differences were not found on self-reported satisfaction related with sex, smoking, alcohol consumption (P<0.05). Self-reported tooth brushing habit was improved in the aspect of brushing time and frequency. Significant differences were found on the self-reported oral health status, self-satisfaction, and clinical indices between the baseline and second visit data (P<0.01). Clinical indices were significantly reduced after using powered toothbrush with a wireless remote display (P<0.01). No adverse reactions were reported during the study period. Conclusions: Powered toothbrush with a wireless remote display successfully promoted oral hygiene from the subjective and objective viewpoint after 30 days of home usage.

Background: Conclusive evidence exists about associations between several life-threatening diseases and passive smoking. The objective of our study was to investigate the prevalence of passive smoking among Iranian dental students, to assess their attitudes towards tobacco control programs, and to explore the association between these two and tobacco use. Methods: In eight randomly selected dental schools, all fourth-year students were surveyed by means of a self-administered anonymous questionnaire in December 2010. The Global Health Professions Student Survey (GHPSS) questionnaire served as the data collection instrument. Exposure to environmental tobacco smoke (ETS) was assessed during the previous week. Chi-square test, logistic regression, and linear regression served for statistical analyses. Results: The response rate was 84% (325 students, 66% female). Exposure to ETS was reported by 74% of the participants. Men were significantly more exposed to ETS at home, and in other places than were women. Most of the students agreed on queried tobacco control policies. The lowest agreement (72%) was for banning smoking in coffee shops and teahouses. A logistic regression model showed that adjusted for gender, passive smoking at home is significantly associated with current tobacco use. A linear regression model suggested that the total score of attitudes is significantly associated with passive smoking at home, passive smoking in other places, tobacco use experience, and current tobacco use. Conclusions: The study reports high exposure to ETS among dental students, and its association with current tobacco use and attitudes towards tobacco control.

Objective : This study came to be carried out in order to develop oral health education program for maintaining adolescents' oral health and to be helpful for qualitative improvement in prevention program by surveying the awareness and behavior on preventive method of dental caries in adolescents. Method : The collected materials of totally 1,100 people who responded were carried out frequency analysis by using SPSS 12.0(Statistical Package for the Social Science). Results : 1. As for the results of awareness on fluoride effect and sealant effect, the students with response to 'effect of preventing decayed tooth' were indicated to be the highest. It was indicated to be the highest in girls as for gender and in the 2nd grade as for school year. (p<0.05). 2. As for the results of being created when eating sweet food and carbonated drink, the students with response as saying that 'a decayed tooth occurs well' were indicated to be the highest. 4. As for the results on the aim of visiting dental clinic, the students with response as saying of 'visiting for having treatment' when tooth is painful were indicated to be the highest. Conclusion : Synthesizing this study, the students' awareness on preventive method of dental caries was high. But the practice on regular check-up or diet was indicated to be low. Through oral health education, the adolescents should be not only delivered information or knowledge, but also changed habit and behavior.

Purpose: Implant beds with an insufficient amount of cortical bone or a loss of cortical bone can result in the initial instability of a dental implant. Thus, the objective of this study was to evaluate the effect of bone cement grafting on implant initial stability in areas with insufficient cortical bone. Methods: Two different circumferential defect depths (2.5 mm and 5 mm) and a control (no defect) were prepared in six bovine rib bones. Fourteen implants of the same type and size ($4mm{\pm}10mm$) were placed in each group. The thickness of the cortical bone was measured for each defect. After the implant stability quotient (ISQ) values were measured three times in four different directions, bone cement was grafted to increase the primary stability of the otherwise unstable implant. After grafting, the ISQ values were measured again. Results: As defect depth increased, the ISQ value decreased. In the controls, the ISQ value was $85.45{\pm}3.36$ ($mean{\pm}standard$ deviation). In circumferential 2.5-mm and 5-mm defect groups, the ISQ values were $69.42{\pm}7.06$ and $57.43{\pm}6.87$, respectively, before grafting. These three values were significantly different (P<0.001). After grafting the bone cement, the ISQ values significantly increased to $73.72{\pm}8.00$ and $67.88{\pm}10.09$ in the 2.5-mm and 5.0-mm defect groups, respectively (P<0.05 and P<0.001). The ISQ value increased to more than double that before grafting in the circumferential 5-mm defect group. The ISQ values did not significantly differ when measured in any of the four directions. Conclusions: The use of bone cement remarkably increased the stability of the implant that otherwise had an insufficient level of stability at placement, which was caused by insufficient cortical bone volume.

Mitis-salivarius sucrose bacitracin(MSB) medium is widely used in the selective isolation of mutans streptococci(MS), a designation for a group of oral cariogenic species. Recently, we have isolated three bacterial strains grown on MSB agar from human dental plaques. The three strains exhibited biochemical characteristics similar to those of the biotype IV of MS, with the exception that they manifested a positive reaction for arginine deaminase. The objective of this study was to identify and characterize these three clinical isolates. The bacteria were identified with biochemical tests as well as by 16S rDNA cloning and sequencing. In order to compare the antibiotics susceptibility of the clinical isolates with that of type strain, the minimum inhibitory concentrations of 9 antibiotics were determined using broth dilution assays. The results identified all of our three clinical isolates as Enterococcus faecalis. All E. faecalis strains were found to be susceptible to penicillin G, amoxicillin, augmentin, and vancomycin, but were resistant to ciprofloxacin, cefuroxim axetil, and clindamycin. Our findings indicate that E. faecalis is capable of growing on MSB agar, and suggest that the MSB medium be improved so that only MS should be recoverable on the medium, as originally devised for their selection.
