Objectives : The removal of most reliable mechanical dental plaque that is to say tooth brushing was generalized to control of dental plaque, many oral health goods have also developed due to the effect differences followed by individual habit. The electric toothbrush have studied and developed widely as major field of study that electric toothbrush having various moving phase was sold and developed at the market. Methods : Accordingly author studied about selling electric toothbrushes shape (vibration type, ultra-sonic minuteness vibration type, semi rotation type) to raise the efficiency after comparing to the moving them that total 8 groups classified by poor tooth models for example normal set of tooth, crowding tooth, bracket attached tooth, prosthetic status etc. and executed plaque removal effect on the tooth through comparing experiment. Results : The removal rate of artificial plaque on the tooth was improved in proportion to the increase of tooth brushing time(p<0.05). The ultra-sonic minuteness vibration and semi rotation type was superior to toothbrush of vibration type comparing to the removal rate of plaque on the tooth(p<0.05). Conclusions : The electric toothbrush of supersonic minuteness vibration and semi rotation type can be recommended most of tooth types regardless of oral tooth setting status for example, normal set of tooth, crowding tooth, bracket attached tooth, porcelain tooth.

Purpose: To test the plaque-removal efficacy of a single-tufted toothbrush on the posterior molars compared with a flat-trimmed toothbrush. Methods: Forty-nine subjects were selected. Professional instruction and written brushing instructions were given. After thorough supra-gingival scaling and polishing, all subjects were asked to abstain from oral hygiene procedures for 24 hours prior to the first experiment. The subjects were randomized to a treatment sequence. The modified Quigley and Hein plaque index was recorded pre- and post-tooth brushing, at 6 surfaces of the posterior molars. After a wash-out period, all the remaining plaque was removed professionally. Twenty-four hours of brushing abstinence was again performed. The plaque index was recorded pre- and post-tooth brushing after the subjects were given the second toothbrush in the cross-over sequence. Results: The percentage reductions in plaque scores achieved with the single-tufted brushes were significantly higher than those of the flat-trimmed brush at the maxillary buccal interproximal, marginal and mandibular lingual interproximal site. The other locations showed no significant difference. Conclusions: The results of the present study implied that the single-tufted brush could be an effective tool for the removal of plaque at some, but not all, sites of the posterior molars.

The relationships between children's health behavior and variables that effect children's health behavior has been investigated in a number of previous studies. This study was conducted to examine the effects of a peer's social reinforcement on children's dental health behavior in an elementary school. The research design was a nonequivalent pre and post-test quasi-experimental design and the study subjects with one hundred and thirteen eight to nine years old children, and their mothers (57 experimental group, 56 control group) were selected as a study group. Subjects were selected by the convenience sampling method. The study was carried out in an elementary school in Namwon city, Korea, from the 26th of April to the 12th of June in 1999. Data were collected in both the pre and post-test portions. Using the "Health Belief Model", each item of the questionnaire for measurement of dental health behavior was modified and administered for the children and their mothers. The questionnaire for the measurement of dental health behavior was developed by Oh, Y.B.(1994). The Cronbach's ${\alpha}$ of the questionnaire for children were .81, and for the mother were .79. In this study, the health belief model consists of "perceived susceptibility", "perceived seriousness", "perceived barrier", "perceived salience", and "perceived benefit". The questionnaire for the children was composed of 37 items, and the questionnaire for the mother was composed of 40 items. Data were analyzed by frequency, ${\chi}^2-test$, ANOVA, Pearson's Correlation, and multiple regression analysis by a SAS program. The results of this study were summarized as follows ; 1. The first hypothesis that the experimental group would have more change in the frequency of brushing per week than that of control group was accepted(t=3.817, p=0.000). Mean tooth brushing scores in the experimental group improved significantly from pre-test to post-test, but in the control group there was no significant improvement in tooth brushing scores. 2. The second hypothesis that the experimental group would have more change in score of dental health behavior than that of control group was accepted(benefit : t=2.804, p=0.006, salience: t=2.608, p=0,010). An evaluation between the experimental group and the control group showed significant change from pre-test to post-test in health behavior scores. 3. The third hypothesis that higher scores of social reinforcement would create more change in the scores of tooth brushing frequency in the experimental group was accepted(${\beta}$=0.169, p=0.000. Multiple regression was used to examine the peer's social reinforcement scores and the relative influence of significant variables in previous ANOVA and Pearson's correlation test on children's frequency of brushing during the post-test. The results of the study indicated that the combination of social reinforcement of peers with variables pertaining to mother and householder were significantly related and effectively improved a child's tooth brushing.

Objectives： Oral health care program for the elementary school children (ESOHCP) should be met the first priority because dental caries are highly sensitive and prevalent among them. This study was performed to enhance the efficiency of ESOHCP, and their oral health promotion. Methods： The Subjects were 346 students (3rd grade 163, 6th grade 185) of one elementary school in Busan. Dental IQ and actual oral health status； the decayed, mixing and filling teeth were checked through questionnaire and oral health examination from April to June 2002. Dental IQ was presented out of one hundred, and data analysis was done using SAS (ver 8.1) program. Results： The students' cognitive level about the causative and preventive factor of dental caries was relatively high. However, the practical aspects of preventive behavior - tooth brushing； three times per day (20％), three minutes per time (22％), oral health examination； one time per three months (10％) left much to be desired. And, only 27％ of the subjects had experienced in school oral health education. The mean level of dental IQ was 79 out of 100, and 51 ％ and 42％ of them had the decayed and teeth with filling, respectively, with the rate of DMFT 82％, DT 43％, FT 57％. The level of dental IQ was higher in case of having his (her) own tooth brush (p＝0.072), standard tooth brushing (p<0.001) three times per day, post meal, three minutes per time, present experience of oral health examination (p<0.001) and dental clinic visit (p<0.001). The grade of caries was more serious in case of 6th grade (p＝0.059), an absence of his (her) own tooth brush (p＝ 0.090), present experience of oral health examination (p＝0.021), and an absence of regular dental clinic visit (p＝0.003). The frequency of oral health examination (γ＝ 0.620), tooth brushing； times per day (γ＝0.445), post meal (γ＝0.355), expending times per brushing (γ＝0.352), right cognition to the treatment of caries (γ＝0.401), positive attitude to dental treatment (γ＝0.387), the frequency of dental clinic visit for the past one year (γ＝0.152) showed significant correlation with dental IQ. In the multivariate analysis, dental IQ was influenced by the frequency of oral health examination, right cognition to the cause of caries, times of teeth brushing per day, right cognition to the treatment of caries, etc., with adjusted R2＝0.857. Conclusion： Though the students' cognitive level about the causative and preventive factor of dental caries was high, the practical aspects of preventive behavior left much to be desired. Ant the current ESOHCP considered to be still inefficient. However, frequent dental visits had apparent correlation with hish level of dental IQ. The specialized and practical program should be needed for the efficient ESOHCP. Harmonized effort from educational, health and dental society is essential.

Purpose: This study studied and investigated the oral health behavior of students in the Department of Dental Technology at D College at D City. Methods: A self-administrated survey was conducted by students currently enrolled at the Department of Dental Laboratory Technology at D College (June 4, 2015 ~ June 12, 2015), and 320 copies that were available for statistical processing were statistically analyzed by using the SPSS 19.0 Program. Results: Among the survey respondents, 91.6% had experience of dental treatment. The highest response regarding the frequency of tooth brushing appeared to be 'twice' with 44.7%. The responses regarding the time of tooth brushing appeared to be highest for 'before sleeping' with 65.3%, which was followed by 'after breakfast' with 60.6%. To the question asking which areas are brushed during tooth brushing, the response of 'teeth, gum, and tongue' appeared to be highest with 44.4%. Among the respondents, 64.7% experienced scaling, however, the experience rate for scaling appeared to increase in proportion with the increase of class year (p< .001). Regarding the subjective feel for the importance of oral health and necessity of tooth brushing, the scores appeared to be both 4.56. However, the score appeared to be 3.27 regarding one's subjective perception of one's own oral health condition. Regarding one's subjective oral health knowledge level depending on gender, female students showed a meaningfully lower rate (3.12 points) compared to male students (3.29 points) (p< .05), and depending on class, the knowledge level appeared to be meaningfully higher along with the increase in class year (p< .001). The experience of receiving oral health education appeared to be 78.4%, and 88.8% of the respondents responded that there is need for oral health education, however, the intent to participate in an oral health education program appeared to be 56.6%. Conclusion: As a result of the study, it could be concluded that oral health management behaviors and awareness of the students at the Department of Dental Technology at D University to prevent oral diseases were rather poor.

Purpose: The purpose of this study was to examine the effect of tooth-brushing oral care on oral health and ventilator-associated pneumonia of patients in Intensive Care Unit (ICU). Methods: A total of 74 participants were recruited from a medical, surgical, or neurosurgical ICU at S Hospital in Seoul, Korea, from September of 2010 to January of 2011. An experimental group (n= 36) received oral care with tooth-brushing while a control group (n=38) received oral care with cotton ball and gauze. In both group, the oral care was done three times a day at least one minute for 7 days. Oral health was examined by the Modified Oral Assessment Guide before the intervention and each night. Results: There is no difference between the groups in aspect of passage of time (p = .603), interaction between time and intervention (p =.300), the performance intervention (p = .766), and the incidence of VAP (p = .486). Conclusion: The effect of oral care with tooth-brushing on oral health and VAP was not different from that of usual oral care in ICU. However, further study is necessary due to high attrition in this study.

The purpose of this study was to evaluate the long term tooth-brushing effect on the color change of specially treated IPS Empress porcelain surface. Staining techique with blue stain and liquid was used. The surfaces of the specimen were treated with 5% and 10% Hydrofluoric acid, 50mm and 250mm alumina sandblast, and then blue stain and liquid were used for external stain. After 29,200, 58,400, 87,600, 116,200 brushing strokes (equivalent to 2, 4, 6, 8 years each), color changes of the stained layer were measured with spectrophotometer(CM-3500d, MINOLTA, Tolkyo, Japan). The result of this study was obtained as follows : 1. The color changes were great after 29,200 tooth brushing strokes in every group, but from 29,200 strokes to 116,800 strokes, there were no significant color changes in each group. (p>0.05) 2. The greastest color changes were observed in 5% HF treated group and the least color changes were observed in $50{\mu}m$ aluminar sandblast treated group in every stroke (p<0.05), but no statistical difference between groups compared with control group (p>0.05). According to these results, pretreatment of I.P.S. Empress porcelain with alumina sandblast improved the color stability It is thought that about 8 year-tooth brushing strokes does not change the color of IPS Empress porcelain significantly on this condition, but long term follow-up will be needed.
