Objectives : The purpose of this study was to evaluate the effects of incremental dental care(IDC) program on kindergarten children. Methods : The subjects were 46 kindergarten children aged 6 who wished participation in IDC program during 5 weeks at oral health center in G-college from March to May, 2012. The data of subjects were examined into oral conditions such as toothbrushing method and frequency, modified O'leary plaque index and dental caries activity before and after IDC program. The collected data were analyzed by SPSS statistical package version 19.0. Results : 1. The rolling and fones methods of toothbrushing increased from 10.8% to 91.3% after IDC program(p<.001). The change of toothbrushing frequency showed that over 3 times a day increased from 52.2% to 76.0% after IDC program(p<.01). 2. The modified O'leary plaque index of before toothbrushing education increased from 1st visit(score 32.19) to 5th visit(score 57.14) and after toothbrushing education increased from 1st visit(score 64.45) to 5th visit(score 78.27) during IDC program(p<.001). 3. As a results of dental caries activity test before and after IDC program, it was found that the bacterial numbers in S.mutans and Latobacillus reduced from 0.74, 0.70 to 0.28, 0.41 (p<.01) and the saliva buffering capacity increased from 1.50 to 2.02(p<.001). Conclusions : It is considered very necessary that IDC program should be maintained and extended to dental clinic so as to enhance the oral health state of kindergarten children.

Objectives: Previous studies have reported inconsistent findings in the association between dental diagnostic X-ray exposure and thyroid cancer. This study was a meta-analysis of case-control studies evaluating the association between exposure to dental radiation and the thyroid cancer risk. Methods: We searched the PubMed and EMBASE databases to identify studies on dental radiation and thyroid cancer risks that were published up to September 2018. Quality of studies was assessed using the Newcastle-Ottawa scale. A fixed-effects model was used to estimate pooled odds ratios (ORs) and 95% confidence intervals (CIs) using STATA 14.0. Potential publication biases were evaluated using Egger's test and Begg's funnel plot. Results: From the literature search, we included six case-control studies in this meta-analysis. The meta-analysis using the fixed-effects model found that dental X-ray exposure was associated with 2.34 times increased risk for thyroid cancer (OR=2.34, 95% CI=1.79-3.21). There was no heterogeneity in the data (p=0.662, I² =0%). Egger's test showed that there was no publication bias (p=0.532). Conclusions: This meta-analysis confirmed the association of dental X-ray exposure and thyroid cancer risk. The current results underscore the importance of applying safety regulations at dental clinics to protect thyroid glands during dental radiography examinations.

Background: We aimed to assess the dose needed to achieve the propofol effect-site concentration using target-controlled infusion in intellectually disabled patients and to detail the most effective method for achieving a safe level of consciousness without hemodynamic changes as well as detail any resulting adverse effects. Methods: We performed a retrospective review of sedation service records of 138 intellectually disabled patients (51, mental retardation; 36, autism; 30, brain lesion, 12 genetic diseases, 9 dementia) aged over 15 years and weighing over 30 kg. These patients had received propofol via target-controlled infusion in the special care dental clinic of Seoul National University Dental Hospital from May 2008 to September 2018 for restorative treatment (112), minor surgery (13), prosthodontics (7), periodontics treatment (5), and implant (1). Results: For all groups, the duration of dental treatments was $43{\pm}18$ minutes, total sedation time was $73{\pm}23$ minutes, and total BIS values was $57{\pm}12$. The propofol maintenance dosage values for each group were: mental retardation, $3{\pm}0.5(2-4){\mu}g/ml$; autism, $3.1{\pm}0.7(2-5){\mu}g/ml;$; brain lesion, $2.8{\pm}0.7(1.5-5){\mu}g/ml;$; genetic disease, $2.9{\pm}0.9(1-4){\mu}g/ml;$ and dementia $2.3{\pm}0.7(1-3.4){\mu}g/ml;$. Conclusions: The dementia group needed a lower dosage to reach a safe, effective propofol effect-site concentration than the other groups. Since there were no complications, deep sedation is a great alternative to general anesthesia for dental treatment of intellectually disabled patients.

Objectives : The purpose of the study is to investigate the correlation between the pain, depression, dental anxiety in the patients visiting to dental clinic for the ultrasonic scaling treatment. Methods : The study is a cross-sectional correlation study. A self-reported questionnaire was filled out by 254 patients having no history of mental illness in Seoul and Gyeonggido from December 12 to 20, 2013. The study instruments included modified Beck's Depression Inventory (BDI), STAI items by Spilberger, Humphis' Modified Dental Anxiety Survey(MDAS), and Visual Analogue Scale. Results : There existed correlation between the ultrasonic scaling pain, depression, dental anxiety, trait anxiety, and state anxiety. Dental anxiety was the most influencing factors on the pain. Conclusions : It is very important to reduce the anxiety in the patients more actively.

Ophiopogonin D (OPD) is a steroidal glycoside derived from Ophiopogon japonicus, a traditional Chinese medicine with diverse biological activities, including antithrombosis, anti-inflammation, and antitussive effects. To investigate the cellular effects and mechanisms of OPD on oral squamous cell carcinoma, cell viability was explored, and the effects of OPD on cell cycle regulators, apoptotic marker proteins, and key proteins involved in metastasis and signaling pathways were examined by MTT assay and Western blotting in YD38 cells. OPD strongly inhibited cell proliferation and induced caspase-dependent apoptosis of YD38 cells by suppressing the cell cycle and activating caspase-3 and poly ADP ribose polymerase. Additionally, OPD suppressed the expression of vital proteins regulating metastasis and proliferation within the integrin/matrix metalloproteinases/FAK and AKT/PI3K/mTor pathways. Thus, OPD can be a potential treatment candidate for gingival cancer.

The purpose of this study was to investigate the effects of preschool children's taste preferences on their intake of nutrients and the degree of dental caries. The subjects were 126 preschool children (boys 62 and girls 64) in Daegu area. Their taste preferences and food intake were investigated and their teeth were also examined. The energy intake of boys (1550 kcal) were significantly higher than that of girls (1441 kcal). Daily dietary intakes of nutrients-except niacin and vitamin C-were higher than those of RDA. Vitamin B$_1$ intake of the group preferring a salty taste was significantly lower than that of the other group (p<0.05). Vitamin B$_2$ intake of the group preferring a salty taste was significantly higher than that of the other group (p<0.05). Vitamin C intake of the group preferring a hot taste was significantly higher than that of the other group (p<0.05). The group with a preference for sweet had more experiences of dental caries and more decayed teeth than the other group, but which is not significant. The experiences of dental caries were negatively correlated with protein intake (p<0.01). The decayed teeth were negatively correlated with energy and protein intakes (p<0.01). Our data suggested that taste preferences are associated with vitamins intake and the degree of dental caries in preschool children. It means the sweet preference increased the experiences of the dental caries.
