The prevalence of periodontal disease was steadily increased. The best prevention methods for periodontal disease are teeth brushing and scaling. The purpose of this study was to investigate the status of scaling experience and related factors among some workers. Total 455 workers in 5 manufacturing companies in Gwangju were selected using convenience sampling method. General characteristics, work-related characteristics, oral health-related characteristics and scaling experience were collected by self-reported questionnaires. Chi-square tests, t-tests and multiple logistic regression analysis were performed to investigate the factors influencing the scaling experience using SPSS software. Statistical significance was defined as a p-value＜0.05. The proportion of scaling experience during the past year was 47.0%. In simple analysis, age, current working position, number of oral disease, interest in oral health, use of secondary oral products, oral health screening use, oral health education experience and awareness of scaling inclusion in the National Health Insurance (NHI) coverage were associated with scaling experience. Finally, the odds ratios (ORs) for scaling experience were significantly higher in younger subjects (adjusted OR [aOR], 3.09; 95% confidence internal [CI], 1.60∼5.96), assistant manager (aOR, 2.68; 95% CI, 1.55∼4.63), subjects with high interest in oral health (aOR, 2.15; 95% CI, 1.02∼4.52), subjects with oral health screening use (aOR, 2.76; 95% CI, 1.50∼5.11) and awareness of scaling inclusion in the NHI coverage (aOR; 2.91, 95% CI, 1.80∼4.72) in multiple logistic regression analysis. Scaling experience was relatively low (47.0%). The related factors with scaling experience were age, working position, use of screening and awareness of scaling inclusion in the NHI coverage. Considering these factors will increase the utilization rate of scaling.

Objective: This study aimed to see the characteristics and satisfaction factors of users at a dental center for the disabled in Gwangju and present basic data that could provide high-quality healthcare service. Data were collected from 218 users, and result were obtained as follow.Methods: 218 users of Gwangju dental center for the disabled participated in this study from July 27 to October 31, 2015. Frequency analysis was performed for the general characteristics and utilization status; the mean and standard deviation were estimated for dental care service satisfaction; independent t-test and one-way ANOVA were performed for the mean differences in satisfaction by the general characteristics; and Scheffe test was carried out in case of significant differences. Results:Mentally disordered patients or users accompanying them were generally most satisfied; in particular, satisfaction with the facility environment and medical technology differed statistically significantly. Conclusion:On the basis of these results, it is necessary to make users of dental centers for the disabled more satisfied by making healthcare service at the center more accessible and by giving more support to the facility environment and medical technology for each disability type with the objective of making the center more usable.

ObjectivePhendimetrazine is an amphetamine analogue that acts as a sympathomimetic with anorectic properties, used for weight loss. There is scarce information on the safety of phendimetrazine associated with fetal anomaly when used early in pregnancy. Some studies suggested that use of phendimetrazine during pregnancy may increase the risk of cleft lip and palate, and congenital diaphragmatic hernia. The aim of the study was to evaluate fetal outcomes among pregnant women who were inadvertently exposed to phendimetrazine in early pregnancy. MethodsTotal 62 singleton pregnant women who were inadvertently exposed to phendimetrazine during early pregnancy were prospectively followed up (twin pregnancy was excluded). In addition, 122 age and gravity matched pregnant women were not exposed to any potential teratogenic agent during pregnancy were recruited as controls. ResultsMean age of exposed women was 33.2 ± 4.9 years, with mean gravity was 2.2 ± 1.1 and mean gestational weeks at exposure was 4.2 ± 2.0. All gestations were confirmed by ultrasonography. Of exposed women, 3 (1.0%) had spontaneous abortions, 2 had artifi cial abortion, 23 cases were lost to follow-up and 7 cases were transferred to other hospital. Therefore, 26 pregnancies inadvertently exposed to phendimetrazine were evaluated. Two babies had abnormal outcome: one had choroid plexus cyst, another baby had bilateral equinovarus. In control group, 11 babies were born with abnormal outcome (7.7% vs. 12.0%; P = 0.54; odds ratio, 0.61; 95% confi dence interval, 0.12 to 2.96). ConclusionThese preliminary results suggest that phendimetrazine may not pose substantial fetal risks. Although more information is needed, there is a critical need for further research on medication used during pregnancy.
