The purpose of this study was to offer the importance on factors of selecting dental institution according to general characteristics targeting general dental patients, and the information of having important influence upon choosing dental clinic and dental hospital. The survey was carried out from August 2009 to September. As a result of analyzing SAS(ver 9.1), the following conclusions were obtained. In the importance on factors of selecting dental institution according to general characteristics, it was thought to be important in convenience of movement or mobility such as distance, transportation, and parking convenience according to age level. According to final academic background, the importance in a factor of rumor in dental clinic was high(p < 0.05). According to job, the significant difference was shown in rumor of dentistry and parking convenience(p < 0.05). According to income, the factor in the appearance of training a medical specialist was indicated to be statistically higher in the group with over 5 million won than the group with under 2 million won(p < 0.05). Given seeing the distribution of opinion about dental hospitals (comparison with dental clinics), the excellence in the medical staff's ability was indicated to be the highest in all of the factor of influencing the use satisfaction(${\beta}=0.18$), the factor of influencing the recommendation level(${\beta}=0.21$), and the factor of influencing the re-use intention(OR=2.09).

The purpose of this study was to compare between early childhood teachers and mothers in oral health knowledge, oral health care behavior, and perception of oral health education. The subjects in this study were 90 early childhood teachers who worked in all of kindergartens and child-care centers and 235 mothers who have young children (aged from 1 to 5) in 2 kindergartens and 2 childcare centers Y region. They completed questionnaires about oral health knowledges, oral health care behaviors, and perception of oral health education. The collected data was analyzed by descriptive statistics, $x^2$-test, and Fisher's exact test of SPSS WIN. The results were as follows: 1. There was not statistically significant difference between early childhood teacher's knowledge about oral health and mothers'. 2. There was statistically significant difference between early childhood teachers' oral health care behaviors for children and mothers' in prevention of cavity, keeping toothbrushes, guiding oral health behaviors, and check up at dentist's. 3. There was statistically significant difference between early childhood teachers' perception of interest and experience in oral health education and mothers'. Therefore, There was not difference between early childhood teacher's knowledge about oral health and mothers. But early childhood teachers more frequently carry out preventing of cavity, keeping toothbrushes, guiding oral health behavior to their children than mothers. Mothers were more interested in oral health than early childhood teachers. And Mothers wanted to be educated about children' oral care and early childhood teachers wanted to be educated about guidebook and media of oral health education.

Cerebral palsy is one of the primary handicapping conditions of childhood. The prevalence of malocclusions in patients with cerebral palsy is approximately twice than in general population. Even though these high rates of malocclusions, most clinicians may feel uncomfortable about treating such problems to reduce inclination of anterior teeth because to reduce of protrusion makes to decrease risk of trauma. This is the case report about mitigation of maxillary anterior teeth protrusion in patient with cerebral palsy. A 14 year old boy who had cerebral palsy visited our dental hospital. He had severe protrusive maxillary anterior teeth and narrow arch form. He was experienced at using Castillo morales appliance in early childhood. He had mild mental retardation and was able to learn simple skills. He and his parents had willing to improve his dental problems. A gentle impression taking on maxilla was done. Removable appliance was made including median screw and labial bow. We provide a period of adaption for 3 weeks. After of anterior teeth through activation of labial bow was done once a month by dentist. The treatment carried out for 10 months and we could observe reduced labial inclination of maxillary right central incisor and more wide arch form. Hawley type retainer was set at maxilla for retention. In conclusion, accompanying careful case selection and treatment, patient with cerebral palsy can be treated and should not be ignored their orthodontic needs.

Daejeon school-based toothbrushing program using toothbrushing room started at 2007. Ministry of Health and Welfare started national toothbrushing room program without pilot project at 2011. The aim of this study was to provide the basic data to assess of the effect of this program. 59 experimental subjects and 60 control subject were selected after written consent. Oral Examination was done by 1 dentist using WHO standard and Survey of Child Oral Health-Related Quality of Life(COHIP), oral health knowledge and oral health behavior were done using self-registration form. We analyzed the result after adjusting economic status and subjective for the difference between experimental and control groups using SPSS 19.0. The experimental group had lower plaque index, better COHIP and more oral health knowledge significantly(p<0.05). But, The significance was not found in dental caries index and oral health behavior. We suggested the oral health education program and other dental caries prevention program including sealants were needed to prevent dental caries, although school-based toothbrushing program could improve COHIP.

This study was conducted to investigate the effects of professional oral healthcare program in eldery residents long-term care facilities. Ninety-four elderly residents from 5 different facilities in Asan participated in this study. The subjects were divided into 3 groups, with 32 in experimental group I, 30 in experimental group II, and 32 in the control group. Subjects in experimental group I were treated by a dental hygienist with professional oral healthcare and received daily oral care from caregivers who had completed elderly oral healthcare course. Subjects in experimental group II received daily oral care from caregivers who had completed elderly oral healthcare course. Control group received daily oral care from caregivers. These 3 groups were tested for dental plaque, halitosis, tongue coating, and salivary flow at baseline, and after 4 and 12 weeks of treatment. There were significant differences in the dental plaque index between the groups, mediate times, and mediate methods, in halitosis between the mediate methods, and in tongue coating between the mediate times, as well as the mediate methods. Finally, salivary flow was significantly different with regard to mediate methods between experimental group II and the control group. Therefore, to improve the oral health condition of elderly residents, involvement of a part-time dentist and scheduled professional oral healthcare are necessary. Furthermore, elderly oral healthcare education for nursing staff, including managers, should be provided.

The purposes of this study were to understand the oral health promotion behavior and dental health condition of primary school children and to examine the relationships between the two variables. For that purpose, 729 fifth and sixth graders from four primary school located in Seoul were surveyed. In addition to the survey responses, dental examination results were used for analysis. The findings were as follows: 1. The children scored 3.51 out of full 5 points in oral health promotion behavior. they scored the highest at 3.82 in dietary habits, which were followed by going to a dentist for prevention purposes at 3.43, the method and frequency of brushing teeth at 3.40 and the use of fluorine at 3.39. 2. It turned out that 46.9% of the children had decayed permanent teeth. The number of decayed teeth was $1.66{\pm}2.32$, that of missing teeth was $0.03{\pm}0.24$. 3. There were reverse correlations(r = -0.32) between the children's subjective perception of their dental health condition and decayed teeth. The more positive perceptions they had for their own dental health condition, the less decayed teeth they had(p < 0.01). 4. There were also reverse correlations(r = -0.10) between the children's oral health promotion behavior and decayed teeth. The more they were engaged in Behavior of alimentation, the less decayed teeth they had(p < 0.01). The results indicate that primary school children can keep their dental health by practicing the right oral health promotion behavior, which calls for a need to develop and apply dental health education programs to promote the oral health promotion behavior among primary school children.

Many people in Korea suffer from a fear of dental treatments; however, only a few studies have focused on this population. This study assessed the effectiveness of cognitive behavioral therapy (CBT) and its interventions in reducing dental anxiety, especially when administered by trained dental staff. Using case studies, the authors analyzed the content of each session and examined the process of reducing dental anxiety. First, the authors observed that the results of both dental fear scale and subjective unit of disturbance decreased significantly with changes in cognitive distortions related to dental anxiety and that rapid improvements were noted after two therapy sessions. Second, the study reported that practicing relaxation (deep-breathing) and muscle relaxation techniques; using hand signals to indicate anxiety or discomfort; establishing an empathic relationship with the therapist; making an anxiety list; and graded insensitive and exposure along with rehearsal, were effective in coping with dental anxiety and in changing negative thoughts towards the dentist. Third, a simple cognitive behavioral intervention can be effective in reducing dental anxiety. In summary, a short-term, five-session psychological intervention with CBT produced a sustained decrease in the symptoms of dental anxiety, allowing the patients to receive the required procedures. The authors discussed the study limitations and the implication of their results on future research.

Purpose: This study assessed marginal bone remodeling and soft tissue esthetics after the loading of single bone-level implants in the anterior maxilla. Methods: An open, single-arm observational clinical trial with 3 years of follow-up was performed, including 22 implants. The patients presented with a single tooth gap in the anterior maxilla (tooth positions 14-24), with natural or restored adjacent teeth. An implant was placed at least 8 weeks post-extraction and healed submerged for 6 weeks. After the second-stage operation, a fixed provisional prosthesis was provided. The final restoration was placed 6 months after the provisional restoration. The time of the provisional crown connection was considered to be the baseline in this study. Esthetic parameters and the marginal bone level were assessed at 6, 12, 24, and 36 months. Results: All implants were well integrated in the bone. A statistically significant increase was found in the mean implant stability quotient between the time of the provisional prosthesis and the time of the final prosthesis. Most implants (95.5%) revealed marginal bone resorption (<0.5 mm), and just 1 implant (4.5%) showed a change of 2.12 mm from baseline to 36 months (mean $0.07{\pm}0.48mm$), while the crestal bone level decreased significantly, from $2.34{\pm}0.93mm$ at baseline to $1.70{\pm}1.10mm$ at 36 months. The facial gingival margin and papilla were stable and the esthetic scores indicated high patient and dentist satisfaction. Conclusions: Platform-switching bone-level implants placed in maxillary single-tooth gaps resulted in successful osseointegration with minimal marginal bone resorption. The peri-implant soft tissue was also esthetically satisfying and stable.
