Objectives: The purpose of this study was to assess the effect of mothers education attainment on prevalence of dental caries among their preschool children. Methods: Data were obtained from the third 2006 Korea National Oral Health Survey. A total of 515 preschool children aged 2 to 7 years and their mothers were selected in this study. We used mother's education level as her socioeconomic position and controlled children's tooth brushing frequency, tooth brushing before bed, the frequency of eating snack, and the preventive dental visit. Whether children experienced dental caries or not and the number of decayed or filled or missing tooth surface they had were used as outcome variables. Results: The proportion of children affected with dental caries was 46.21%. The mother's education level affected children's caries significantly (p<0.05) and children whose mother attended less than high school had more possibility of having caries than children whose mother graduated from college or more (p<0.05). This effect was still significant and got larger(p<0.05), even after controlling children's dental health behavior. Conclusion: This study showed that mother's education level affected the prevalence of caries among their preschool children. In addition, this result indicated a need for more definite policy for children's dental health in lower socioeconomic class with general dental education.

The purposes of this study were to investigate the oral health status of the disabled children attending special schools in Seoul and Gyeonggi area, which were to collect baseline data for set up a oral health center in special schools. The study group comprised 915 disabled children aged 12~15 year. They were examined clinically and surveyed on 4 oral health related characteristics according to the type and level of disabilities The results may be summarized as follows: 1. DMFT index was the highest in children with crippled disorder. The plaque control was more required to the children with mental retardation or developmental disorder other than another types of disabilities. 2. About one third of the children with mental retardation or developmental disorder had their teeth brushed at least 3 times daily without any help. Over the half of the children with crippled disorder had their teeth brushed 2 times daily, 33.3% were independent and 38.9% totally dependent on help from others. 3. The more level of disabilities was higher, the more frequency of tooth brushing was lower and degree of dependance of the tooth brushing was higher. 4. There was tendency to visit to dental office more frequently for relief of dental symptoms in children with crippled disorder 5. The inability to call for help from others was the major barrier to dental care for the disabled.

The purpose of this study to provide base data of various dental hygiene management systems are necessary to improve the oral health of visitor oral prophylaxis practice units, investigating and analyzing the oral health behavior and awareness of 130 scaling patients who visited the oral prophylaxis practice units of J Health College from April to May of the year 2007. The following conclusions were obtained 1. 50% of them had more than 2 times of toothbrushing a day, and 45.5% had more than 3 times of toothbrushing a day. 2. Toothbrushing was done after having a breakfast in 75.4% and 71.5% brushed their teeth after having a dinner. As the time to brush teeth, 45.4% of the subjects spentless than 3 minutes and 39.2% of them spent less than 2 minutes, and 48.5% of them bushed their teeth in up and down directions and 43.8% used mixed approaches. 3. The usage period of a toothbrush lasted about 3 month in 33.1% and 26.2% used a toothbrush about 2 month, and 20% of the subjects had the experience of using dental floss or interdental brush. 4. 61.5% of the subjects had the experience of having scaling treatment. The frequency of scaling was found to be 38.5%. 5. As the cause of having caries of the teeth, 73.8% responded it as unfaithfully brushing and 50% the subjects considered smoking is very harmful to dental health. 6. The most important behavior for dental health was found to be not eating sugars that were pointed out by 75.4% of subjects. Based upon the above listed study results, various dental hygiene management systems are necessary to improve the oral health of patients who visit oral prophylaxis practice units, especially, the correct toothbrushing and periodic oral examination with preventive scaling were thought to be necessary.

Objectives: The purpose of the study is to investigate the related factors to dental care utilization, oral health behaviors, and oral health status in immigrant workers in Korea. Methods: The subjects were 504 foreign immigrant male workers over 20 years old who visited Daegu labor consultation center for oral health survey and oral examination. The questionnaire included 5 questions of socioeconomic characteristics, 8 questions of oral health practice behavior, 6 questions of dental clinic visit, 8 questions of social relations and Korean language proficiency. The question for health behavior was measure by body mass index(BMI). Social relations and Korean language proficiency instrument was modified by Seol from "Family welfare survey in Korean international marriage" and scored by Liker 5 scale. Results: The oral health examination of the immigrant workers was as follows: decayed teeth - 76.6%, filling teeth - 27.4%, missing teeth - 69.8%, dental caries experience above five or more - 60.2%, periodontal pocket tissues - 58.9%. Simplified Oral Hygiene Index was very poor and accounted for 49.0%. Dental care utilization experience was closely associated with social relation indexes including attendance in family events, household stuff help, financial help and counseling for hard work(p<0.01). Dental care utilization experience proportionally increased with proficiency in Korean literacy including speaking, listening, and writing abilities of Korean language(p<0.01). Conclusions: In order to improve the oral health condition of the immigrant workers, it is important to provide social network, Korean language proficiency support, and health insurance coverage through economic burden reduction by the Korean government.

Objectives: The purpose of this study was to explore and analyze experiences with home-visiting oral health education in vulnerable populations and to provide foundational data necessary for the development of preventive strategies for oral health promotion among these patients. Methods: Using a phenomenological research, in-depth interviews were conducted between August 29 and October 31, 2023 with 20 vulnerable individuals participating in the Home Visit Oral Health Education Program under the Gwangju+ Gwangsan Integrated Care Service project spearheaded by the Gwangju Medical Welfare Cooperative. Results: After analyzing the contents of the participants' experiences, 130 meaningful words and 14 subcategories were identified and categorized into five major themes. Participants expressed discomfort when chewing or swallowing food and felt burdened by visits to the dentist. Although they experienced considerable loneliness because they spent a significant amount of time alone, they enjoyed communicating through visitation care and expressed gratitude for receiving oral health education. Conclusions: Oral health education through home visits cam increase awareness of oral health management among vulnerable populations and serve as an important means of improving their quality of life.

Objectives: This retrospective cohort study examined the incidence of interappointment emergencies during multiple-visit molar root canal treatments conducted by undergraduate students. Treatments performed without the use of intracanal medicament were compared to treatments that incorporated calcium hydroxide as an intracanal medicament. Materials and Methods: Interappointment emergencies, defined as instances of pain or swelling that required the patient to make an unscheduled follow-up visit, were recorded for up to 2 months after the intervention. To avoid the influence of obturation on the observed incidence of emergency visits, only unscheduled visits occurring between the start and end of the root canal treatment were included. Results: Of the 719 patients included in this study, 77 (10.7%) were recorded as experiencing interappointment emergencies. Of these emergencies, 62% occurred within 2 weeks following the most recent intervention. In the group of patients who did not receive intracanal medicament, the incidence of interappointment emergencies was 11.9% (46 of 385 patients). In comparison, this rate was 9.3% (31 of 334 patients) among those who received calcium hydroxide as an intracanal medicament (odds ratio, 1.33; 95% confidence interval, 0.82-2.15; p = 0.249). Conclusions: Interappointment emergencies may arise at any point during root canal treatment, but they most commonly occur within the first 2 weeks following intervention. The omission of intracanal medicament in multiple-visit molar root canal treatments, performed by undergraduate students, did not significantly increase the incidence of these emergencies.

Purpose: The aim of this retrospective study was to investigate the cumulative success rate, the implant survival rate, and the occurrence of biological complications in implants supporting full-arch immediately loaded rehabilitations supported by upright and tilted implants. Methods: The clinical records and periapical radiographs of patients who attended follow-up visits were collected, and information was recorded regarding marginal bone loss resorption, the occurrence of peri-implant infectious diseases, and the implant survival rate. Implants were classified as successful or not successful according to two distinct classifications for implant success. Results: A total of 53 maxillary and mandibular restorations including 212 implants were analysed, of which 56 implants were studied over the full five-year follow-up period. After five years, the cumulative success rate was 76.04% according to the Misch classification and 56.34% according to the Albrektsson classification. The cumulative implant survival rate was 100%, although one implant was found to be affected by peri-implantitis at the second follow-up visit. Conclusions: The cumulative success rate of the implants dropped over time, corresponding to the progression of marginal bone resorption. The prevalence of peri-implantitis was very low, and the implant survival rate was not found to be related to the cumulative success rate.

Objective: To investigate the dental phenotypes and treatment modalities (Tx-Mod) in Korean patients with Parry-Romberg syndrome (PRS) using longitudinal data. Methods: The samples consisted of 10 PRS patients, who were treated and/or followed-up at Seoul National University Dental Hospital between 1998 and 2019. Using a novel PRS severity index based on the numbers of the atrophy-involved area and asymmetry-involved item, we classified them into mild (n = 3), moderate (n = 2), and severe (n = 5). Dental phenotypes, including congenitally missing tooth (Con-Missing-Tooth), microdontia, tooth with short root (Short-Root), tooth with dilacerated root, and delayed eruption/impacted tooth, were investigated along with Tx-Mod. Results: The side of occurrence of all dental phenotypes showed 100% concordance with the side of PRS involvement. The most two common dental phenotypes were Con-Missing-Tooth and Short-Root (n = 29 and n = 17 in six patients). The sums of the average number of Con-Missing-Tooth and Short-Root increased from mild PRS to moderate PRS and severe PRS cases (1.0, 6.0, and 6.2). In terms of Tx-Mod, growth observation due to mild atrophy, fixed orthodontic treatment, and grafting were used for mild PRS cases. Tx-Mod for moderate PRS cases involved growth observation for surgery due to an early age at the initial visit. For severe PRS cases, diverse Tx-Mod combinations including unilateral functional appliance, fixed orthodontic treatment, growth observation, grafting, and orthognathic surgery were used. Conclusions: The novel PRS severity index may be useful to provide primary data for individualized diagnosis and treatment planning for PRS patients.

With regard to toothbrushing method, the most of the male patients(43.8%) brushed their teeth by rolling the toothbrushes up and down, and the most of the female patients(46.1%) did that both up and down and right and left. As to the influence of smoking, the largest number of the smokers(50.0%) and nonsmokers(40.4%) brushed their teeth both up and down and right and left. statistically significant differences were shown by gender and smoking(p<0.05). 2. As for knowledge acquisition route on periodontal diseases by gender, there was no way for the men(38.2%) to get the information, and the largest number of the women (43.4%) acquired the information through the internet. With respect to smoking, the largest numbers of the smokers(38.2%) and nonsmokers(37.5%) got the information by the internet, and statistically significant differences were found (p<0.05). 3. Concerning treatment method of periodontal diseases provided by the dental clinic, the largest number of the men(33.7%) got their teeth scaled, and the greatest group of the women(29.6%) had their gums treated. The treatment method made statistically significant differences by gender (p<0.05). Regarding smoking, the largest group of the smokers(32.4%) had their teeth scaled, and the largest number of the nonsmokers(28.7%) got their gums treated. significant differences were made statistically by smoking (p<0.05). 4. As to instruction on the prevention of periodontal diseases, the largest group(63.2%) intended to take that. The second (23.0%) was eager to do it, and the third(13.8%) was unwilling to do it.

Objectives: The purpose of the study was to investigate the subjective oral health status, oral health promotion behaviors, and related factors in the university students in Jeonnam. Methods: A self-reported survey was completed by 480 university students in Jeonnam from June 1 to 15, 2016 based on convenience sampling. The questionnaires consisted of general characteristics of the subjects, subjective oral health status, and oral health promotion behaviors. The collected data were analyzed by frequency analysis, independent t-test, one-way ANOVA and multiple regression analysis among others. Results: The average of subjective oral health status was 3.36 and the oral health promotion behavior was 2.87. It was shown to have influence upon the oral health promotion behaviors in the more the use of oral care products, in the better the oral health condition, in the more dental visit experience, in the more you do not drink, and in the more experience in oral health education. Conclusions: To improve the oral health in the university students, interest, knowledge, attitudes, and behavior in the oral health should be changed through development of oral health education programs. Also, efforts to develop curriculum and establish the university policies will be necessary so as for the university students to have responsibility for general health care including oral health in the universities.
