Temporomandibular joint disorders (TMDs) can occur at any age, including childhood and adolescence, and pain-related TMDs can affect growth and quality of life. In the present study, recent trends in the diagnosis and treatment of TMDs in children and adolescents were analyzed over a 10-year period. Using 10 years of data from the Health Insurance Review and Assessment Service (HIRA) and Jeonbuk National University (JBNU) Dental Hospital, patients between 0 and 19 years of age diagnosed with K07.6 (temporomandibular joint disorders) were analyzed by 5-year bins. Both datasets indicated a higher prevalence in females (1.2-fold in HIRA, 1.5-fold in JBNU) and in ages 15 to 19 years (72.1% in HIRA, 74.7% in JBNU). HIRA reported a 42.3% increase in prevalence per 100,000 people, from 651.4 in 2011 to 927.0 in 2020. JBNU reported K07.66 (masticatory muscle disorders) as the most common diagnosis in subjects under 10 years of age and K07.60 (internal derangement of temporomandibular joint) in those over 10 years of age. In addition, both were treated mainly by a combination of physical therapy and medication, and the treatment rate increased in accordance with age. Because TMDs can affect various structures in the orofacial region and cause pain that tends to differ with age, an early and specific diagnosis appropriate for age is important for treatment. Therefore, pediatric dentists need to promptly recognize TMDs in children and adolescents and consult with specialists as the prevalence increases.

The Status of oral health and dental prosthetic treatment in Daegu and Gyoung Buk area was examined. To investigate the correlation between factors such as demographic and socioeconomic characteristics and status of oral health and knowledge about oral preventive measures, a survey was performed. After analyzing the effects of knowledge levels about dental prosthetic treatment on the oral health status and preventive measures, following results were obtained. A Total of 625 people participated in the survey for three months from October 2007 to January 2008. The responses from the survey were then analyzed to assess whether those with less knowledge of preventive measures tended to have more dental prosthetic work. Of those that took part in the survey: ${\cdot}$ 30.2% were in their twenties ${\cdot}$ 56.2% were married ${\cdot}$ 51.4% of respondents had at least a college degree ${\cdot}$ 42.4% had monthly incomes below one million Won ${\cdot}$ 24.3% were students ${\cdot}$ 55.8% were from urban areas After studying the relationship between oral health and various demographics, researchers concluded that respondents' sex, income, job and place of residence had no effect on the overall status of their oral health. However, those that were divorcees or widows (1.95${_+}/{_-}$ 0.32), over the age of 70 (1.67${_+}/{_-}$0.31), or had little education (0.82${_+}/{_-}$0.28), all demonstrated a statistically significant effect on their oral health with a significance level of 0.05.Cross analysis revealed a p-value of 0.000. The correlation between knowledge of oral preventive measures and other factors was examined. No difference was found between men and women but people who were divorced or lost their spouse, people over the age of 60, and people with no education, the results of knowledge of oral preventive measure was poor as 1.74$\pm$0.44, 1.85$\pm$0.40, 1.85$\pm$0.44,and 1.60$\pm$0.47 separately. Cross analysis showed that p-value was 0.000 and correlation between knowledge of oral preventive measures and those factors were statistically significant at significance level of 0.05. The status of dental prosthetic treatment was investigated. Women, people with higher income, and married people had more dental prosthetic treatment and it was related to education, income, residential area, and the status of dental prosthetic treatment. The returns of those factors was 32.7%. Respondents$^{\circ}{\emptyset}$ oral hygiene status and knowledge of oral preventive measures was related to demographic or socioeconomic factors. Therefore, a preventive program for oral health care needs to be developed in advanced countries. Knowledge of oral health is below the international average and more research and effort needs to be put in to develop public knowledge of dental prosthetic treatment. Government intervention such as enacting an oral health initiative or dental insurance that covers prosthetic treatments is urgently needed.

The purpose of this study was to analyze the relationship between objective oral health status determined by dentists, self-perceived subjective oral health status, and oral health related quality of life (OHRQoL) in the elderly. The related factors affecting OHRQoL in the elderly were also surveyed. Four hundred and thirty elderly individuals who visited the three public health centers and four dental clinics in Busan were selected by convenience sampling. Twelve dental hygienists investigated the subjective oral health status and OHRQoL using the 14-item Oral Health Impact Profile (OHIP-14) and twentyone dentists examined the objective oral health status, including healthy remaining teeth, treated remaining teeth, functional remaining teeth, missing teeth, and non-treated missing teeth. Data were analyzed using SPSS ver. 12.0. OHRQoL was higher when oral and periodontal status was perceived as healthy, when there was no toothache, no interference in mastication, and when study subjects had the ability of food softening. It was also higher when study subjects had ${\geq}20$ remaining teeth and <9 missing teeth, and were wearing denture. The related factors affecting OHRQoL of the elderly were the type of medical insurance, toothache, ability of food softening, perception of periodontal status, and the number of healthy remaining teeth. There was a significant relationship between the subjective-objective oral health status and OHRQoL in the elderly. A continuous oral health care system aimed at retaining ${\geq}20$ healthy remaining teeth is needed to improve oral health and OHRQoL for the elderly, especially for the elderly receiving medical aid.

This study conducted an interview questionnaire survey of 245 old people in some halls for the aged in the Daejeon Metropolitan City from June 1 to 31, 2008. on their attitudes toward and practice items for oral health, resulting in the following findings. 1. In terms of socio-demographic characteristics of the subjects, males females were 48.2% and 51.8% respectively, and in the educational level, no-education, elementary school graduation, middle school graduation, and high school graduation and higher were 27.8%, 33.9%, 26.5%, and 11.8%, respectively, showing the statistically significant difference (p=0.009). 2. In terms of attitudes toward oral health management by oral health care education, regarding questions of use of oral and dental hygiene products (p=0.016), experience in scaling, and whether or not they wear false teeth (p=0.018), a group having received the education rather than a group not having received it showed more positive oral health management attitudes, indicating the statistically significant difference. 3. In daily living inconvenience of acute oral health diseases according to oral health care education, acute oral diseases presents in a group with the education ($2.30{\pm}0.72$) lower than in a group without the education ($2.49{\pm}0.63$), indicating the statistically significant difference(p=0.031). 4. Factors of oral health diseases showed the significant relation with types of health insurance, subjective systemic health status, acute diseases and subjective oral health status (p<0.01), and the explanatory power or the final model was 38%. Accordingly it is thought that there is the indicated need for analyzing and grasping factors related to oral health diseases among the elderly through considering their attitudes toward and practice for oral health, and developing programs of enhancing the oral health of the elderly in order for them to change their attitudes and habits, and also reinforcing oral health care education for the elderly focused on making them perform oral health behaviors in a right way.

Background: Particulate matter (PM) has been extensively observed due to its negative association with human health. Previous research revealed the possible negative effect of air pollutant exposure on oral health. However, the predictive model between air pollutant exposure and the prevalence of periodontitis has not been observed yet. Therefore, this study aims to propose a predictive model for the number of patients with periodontitis exposed to PM and atmospheric factors in South Korea using deep learning. Methods: This study is a retrospective cohort study utilizing secondary data from the Korean Statistical Information Service and the Health Insurance Review and Assessment database for air pollution and the number of patients with periodontitis, respectively. Data from 2015 to 2022 were collected and consolidated every month, organized by region. Following data matching and management, the deep neural networks (DNN) model was applied, and the mean absolute percentage error (MAPE) value was calculated to ensure the accuracy of the model. Results: As we evaluated the DNN model with MAPE, the multivariate model of air pollution including exposure to PM_2.5, PM₁₀, and other atmospheric factors predict approximately 85% of the number of patients with periodontitis. The MAPE value ranged from 12.85 to 17.10 (mean±standard deviation=14.12±1.30), indicating a commendable level of accuracy. Conclusion: In this study, the predictive model for the number of patients with periodontitis is developed based on air pollution, including exposure to PM_2.5, PM₁₀, and other atmospheric factors. Additionally, various relevant factors are incorporated into the developed predictive model to elucidate specific causal relationships. It is anticipated that future research will lead to the development of a more accurate model for predicting the number of patients with periodontitis.

The purpose of this study was to examine how clients who visited dental institutions perceived client services, what sorts of client services were provided to them and to what extent they were satisfied with them. It's ultimately meant to seek ways to enhance and enlarge client services. A survey was conducted on 379 residents who used dental institutions in Seoul and Gyeonggi provinces, and the findings of this study were as follows: 1. 64.6 percent of the people investigated weren't aware of client services, and 33.0 percent viewed them as part of medical services. 77.5 percent had grievances about dental institutions they'd ever used. 2. The biggest complaint was that the dental treatments they received weren't covered by the dental insurance. As for how to solve their grievances, the largest group of them told the employees of the dental institutions about their complaints or didn't use them again. When asked whether the dental institutions took any steps to get rid of their grievances, the greatest group replied they had no idea. and the second largest group answered they took no measure. 3. By age and educational level, those who were in their 60s and up and stopped at elementary school were best cognizant of client services. Among client service variables, they were most satisfied with how the employees handled their complaints, and as to overall satisfaction, their willingness to revisit ranked highest. 4. Concerning connections among client service awareness, service variables and overall satisfaction level, their awareness of client services had a positive correlational relationship with every service variable and satisfaction level. Among the service variables, prompt client services and employee attitude were positively correlated to overall satisfaction level, but service procedure, facilities and information services exercised little impact on that. 5. As for what factors affected their content with client services, their client service awareness was identified as one of the important factors to influence their use of dental institutions, the outcome of their visit and their willingness to revisit. The above-mentioned findings suggested that dental institutions should strengthen publicity activities to inform people of client services, and encourage them to express their grievances. In addition, they should take an immediate action to remove their complaints, and try to get a successful feedback to offer higher-quality medical services and customer-oriented services.

Purpose: The aim of this study was to compare the prevalence, amount, and rate of supraeruption of the maxillary second molar according to sex, age, and history of periodontitis. Methods: Data were collected retrospectively from the charts and panoramic radiographs of 65 patients who were scheduled to undergo implant placement at the site of the mandibular second molar. The amount of supraeruption of the maxillary second molar and the alveolar bone level of the neighboring teeth were measured on digital panoramic radiographs. The prevalence was evaluated in each group, and univariate and multivariate logistic regression analyses were used to identify factors influencing the prevalence of supraeruption. The amount and the rate of supraeruption were compared between pairs of groups using the Mann-Whitney U test. For all tests, P values <0.05 were considered to indicate statistical significance. Results: Supraeruption occurred in 78% of the patients. The prevalence of supraeruption was affected by sex, age, and history of periodontitis. The mean amount of supraeruption was 0.91 mm and the mean rate of supraeruption was 0.14 mm/month. The amount and the rate of supraeruption showed no significant differences according to sex, age, or the distance from the cementoenamel junction to the alveolar bone crest (P>0.05). Conclusions: These results show that the amount of supraeruption on the maxillary second molar was similar to the thickness of the enamel on the occlusal surface. When a single implant is scheduled to be placed on the mandibular second molar, supraeruption of the antagonist should be considered.

Purpose: This study aimed to determine the long-term outcomes after peri-implantitis treatment and the factors affecting these outcomes. Methods: This study included 92 implants in 45 patients who had been treated for peri-implantitis. Clinical data on the characteristics of patients and their implants were collected retrospectively. The change in the marginal bone level was calculated by comparing the baseline and the most recently obtained (≥3 years after treatment) radiographs. The primary outcome variable was progression of the disease after the treatment at the implant level, which was defined as further bone loss of >1.0 mm or implant removal. A 2-level binary logistic regression analysis was used to identify the effects of possible factors on the primary outcome. Results: The mean age of the patients was 58.7 years (range, 22-79 years). Progression of peri-implantitis was observed in 64.4% of patients and 63.0% of implants during an observation period of 6.4±2.7 years (mean±standard deviation). Multivariable regression analysis revealed that full compliance to recall visits (P=0.019), smoking (P=0.023), placement of 4 or more implants (P=0.022), and marginal bone loss ≥4 mm at baseline (P=0.027) significantly influenced the treatment outcome. Conclusions: The long-term results of peri-implantitis treatment can be improved by full compliance on the part of patients, whereas it is impaired by smoking, placement of multiple implants, and severe bone loss at baseline. Encouraging patients to stop smoking and to receive supportive care is recommended before treatment.

치의학계에서는 의료사고를 일으킬만한 중환자나 응급환자의 빈도가 상대적으로 낮아 의료분쟁에 휘말리는 경우가 적었기 때문에, 이에 대하여 비교적 안전지대로 인식되어 왔다. 그러나 요즈음은 남의 일로 보아 넘기기에는 어려울 정도로 의료분쟁이 증가하고 있다. 이런 연유로 최근에 이르러서는 비교적 다양한 의료사고와 분쟁에 관한 연구가 이루어지고 있으며, 적당한 대처를 위하여 관련된 사항을 분석하고 있으나, 자료가 부족한 실정이다. 본 연구는 2004년 현재 서울시치과의사회 소속 개원치과의사 3684명중, 설문지가 회수된 1882명을 연구대상으로 하며, 치과의사를 대상으로 하는 의료배상책임보험이 시행되고 있는 최근의 개원 치과에서 일어나는 의료사고 및 분쟁의 실태와, 일반적인 치과의사들의 의식을 분석하고, 전체적인 흐름을 파악하여 향후대책의 자료를 제시하는 것을 연구목적으로 한 것으로 다음과 같은 결과를 얻었다. 1. 응답자의 98.47%가 향후 의료사고 및 분쟁 발생에 대한 의구심을 가졌다. 2. 응답자의 27.42%가 의료분쟁을 경험하였으며, 전공의 수련여부와 의료분쟁 경험률 사이에는 유의한 차이가 나타나지 않았다. 3. 의료사고 중 치주.보존 관련 사고가 20.50%로 가장 높았으며, 임프란트 관련사고도 6.17%로 나타났다. 4. 응답자의 43.02%만이 치료 전 충분히 설명을 하였으며, 환자의 정확한 동의없이 치료를 시작하는 경우도 25.90%로 나타났다. 5. 설명 및 동의를 시행하지 않아 의료분쟁이 발생한 것은 16.55%이며, 의무기록 관련자료가 부족하여 문제해결에 어려움을 당한 경우는 10.26%로 나타났다. 6. 응급조치를 시행할 수 있다고 생각하는 경우는 49.73%였으며, 이중 정확한 지식을 갖춘 경우는 23.60%로 나타났다. 7. 의료분쟁 발생시 88.09%가 치과의사에게 조언을 구하였으며, 또한 단체로는 구치과의사회에 주로 자문을 구했다. 8. 의료분쟁과 관련하여 소비자보호원으로부터 자료 제출 요구를 받은 경우는 5.26%로 나타났으며, 이들 중 75.61%는 이에 성실히 대응하였다. 9. 의료분쟁을 해결한 후 83.63%는 비교적 안정적인 심리상태를 회복하였다. 10. 응답자의 99.46%가 의료분쟁처리기구가 필요하다고 느꼈으며, 78.58%는 매우 시급하다고 생각하였다. 11. 66.70%의 치과의사가 의료분쟁 경험이 없이도 의료배상책임보험에 가입하였다. 그러나 응답자의 73.36%는 이 상품에 대하여 잘 몰랐으며, 가입자의 93.36%는 분쟁처리과정을 잘 알지 못했다. 12. 79.00%의 응답자가 의료배상책임보험에 가입한 후에는 의료분쟁이 발생하여도 당황스러우나 가입 이전보다는 비교적 안심할 수 있다고 느끼고 있었다. 13. 의료배상책임보험에 의한 분쟁의 해결시 치과의사는 71.92%가 보통이상으로 만족하였으나, 환자는 35.61%만이 만족하였다. 14. 의료배상책임보험의 보완점으로 53.22%가 분쟁의 신속한 해결을 위해서 보험사, 의사, 환자 모두가 합의 유도에 동참해야 한다고 생각하였으며, 또 29.08%의 응답자가 합의과정에서 환자측의 업무방해를 보험사에서 방어해 주기를 바라고 있었다. 이상의 결과들을 볼 때 증가하는 의료분쟁에 대한 인식을 제고하고 이에 대한 교육 및 해결 장치의 보완이 필요할 것으로 사료된다.
