Objectives: The purpose of the study was to find out dental caries and periodontal disease based on oral healthcare of adults in Busan. This study will provide the preventive oral healthcare for the periodontal diseases and dental caries. Methods: The study subjects were 369 people from the regular dental health checkup in the general hospital in Busan. After receiving informed consent, a self-reported questionnaire was completed from October 1, 2014 to January 31, 2015. The questionnaire consisted of dental caries and periodontal diseases by direct examination and toothbrushing method. Data were analyzed by ${\chi}^2$ test, Fisher's exact test, and Pearson's correlation. Results: In the morbidity of dental caries and periodontal diseases, the dental caries was most common in those having restored teeth(236 subjects, 64%), while periodontal diseases were found in mild cases of gingival inflammation in 285 subjects(77.2%), and mild cases of dental calculus in 274 subjects(73.4%). Most of the respondents replied that they did not have systemic disease or oral health related symptoms. According to toothbrushing pattern, dental caries experiences were most common in those having less frequent toothbrushing less than 3 minutes and no tongue brushing. The outbreak of dental caries was more common in 5 times than 3 to 4 times a day. Conclusions: The education of the right toothbrushing method and use of dental floss is the most important prevention of dental caries and periodontal disease in the adults.

Objectives: Although a few studies have investigated the relationship between kidney and oral function (number of remaining teeth), their results remain inconclusive. Therefore, this study aimed to investigate the relationship between kidney function and oral health in community-dwelling healthy elderlies and examine the factors associated with kidney function. Materials and Methods: We used cross-sectional data from the Shimane prefecture cohort recruited by the Center for Community-Based Health Research and Education in 2019. We collected clinical data on dental status, background factors and kidney function (estimated glomerular filtration rate [eGFR], mL/min/1.73 m² and creatinine levels, mg/dL). Results: The study enrolled 481 participants, whose mean age was 66.7±7.4 years, and 223 (46.4%) participants were men. Multivariate analysis revealed significant correlations between eGFR (B=0.17, P=0.04), creatinine (B=-0.54, P<0.01), and the number of remaining teeth. The number of remaining teeth was associated with creatinine and eGFR, which are indicators of kidney function. Conclusion: This study suggests that preserving the teeth may prevent decline in kidney function. Dental professionals should provide instructions and professional care to reduce the risk of systemic diseases such as kidney dysfunction.

Mastoid lymph node inflammation is a rare entity. Pathological conditions in the vicinity of the mastoid processes can be challenging for maxillofacial head-neck surgeons to address. We report a case of suppurative mastoid lymphadenitis in an 18-year-old Caucasian male. To our knowledge, there are no publications that highlight the clinical, ultrasonographic, intra-, and postoperative data for any pathologic process that presented as mastoiditis.

The aims of this study were to investigate the nosocomial infection route of methicillin-resistant Staphylococcus aureus (MRSA) and explore preventative methods for this pathogen that involve blocking its dispersion. We cultured MRSA from nasal cavity swabs collected between June and July 2008 that we obtained from eight dental healthcare providers, 32 nurses and the sputum specimens of two patients from our hospital. In addition, we used VITEK 2 equipment to measure drug sensitivity, and we further performed biochemical testing and pulse-field gel electrophoresis (PFGE) to isolate MRSA colonies. The incidence of these bacteria on the nasal swabs was 25.0% from dental clinic healthcare providers, 13.6% from the internal medicine ward nurses and 30.0% from intensive care unit nurses. Moreover, MRSA was detectable in sputum specimens of ward patients. The antimicrobial agents resistance and partial PFGE types of MRSA showed a similar pattern. We suggest from these analyses that nasal cavity infection by MRSA could occur by cross contamination between healthcare providers and patients which underscores the importance of stringent MRSA management practices.

Measuring and quantifying the burden of disease (BoD) is crucial for healthcare policy-related decisions. For this purpose, summary measures of population health (SMPH) have been proposed to overcome the limitations of prevalence, incidence, and mortality. Oral health remains separated from the mainstream healthcare system, and the lack of reliable epidemiological data has been pointed out as the cause. In this study, we aimed to understand the flow of international and domestic BoD research related to oral disorders and the direction in which those studies should advance in the future. It is necessary to continuously revise the previously measured BoD of oral disorders and calculate the BoD by performing subdivisions, starting from the development of lay descriptions. Furthermore, developing elaborate BoD measurement methodologies that reflect the complexity of the oral cavity is essential.

Purpose: This study was conducted to develop an evidence-based clinical imaging diagnostic guideline for implant planning, taking into account efficacy, benefits, and risks. Materials and Methods: The guideline development process employed the adaptation methodology used for Korean clinical imaging guidelines(K-CIG). Core databases(Ovid-Medline, Ovid-Embase, National Guideline Clearinghouse, Guideline International Network) and domestic databases (KoreaMed, KMbase, and KoMGI) were searched for guidelines. The retrieved articles were analyzed by 2 reviewers, and articles were selected using well-established inclusion criteria. Results: The search identified 294 articles, of which 3 were selected as relevant guidelines. Based on those 3 guidelines, 3 recommendations for implant planning were derived. Conclusion: We recommend radiography or cone-beam computed tomography (CBCT) scanning for individual patients judged to require a cross-sectional image after reading of a panoramic X-ray image and a conventional intraoral radiological image. Various steps should be taken to raise awareness of these recommendations among clinicians and the public, and K-CIG should be regularly reviewed and revised.

Objectives: The purpose of this study is to find out differences in oral health status, defined as their oral health and oral health quality of life among the elderly depending on their income and education levels. Methods: This study used 922 senior citizens over 65 from the data (2015) of the 6th National Health and Nutrition Survey (NHNS). The regression analysis was adopted to identify factors affecting their oral health status which has effect on their oral health quality of life. The statistical package SPSS 21.0 was employed. Frequency analysis, chi-squared analysis and regression analysis were used, and the significance level or Cronbach's alpha value was 0.05. Results: Depending on income levels, there were differences in their oral health status as to whether they use oral hygiene products, take dental examinations, join private health-insurances, and delay dental treatments or not. And educational levels also made significant differences in their oral health status as to whether they smoke, drink alcohol, how many times they brush teeth a day, whether they use oral hygiene products, take dental treatments, and join private health-insurances. Regression analysis on the relationship between their oral health status and the oral health quality of life showed that there were significant differences depending on whether they take dental treatments, delay dental medical treatments, smoke, take oral examinations, how many times they brush teeth a day, and whether they use oral hygiene products, or join private health-insurances. Conclusions: The study shows that a comprehensive plan is needed to raise attention on proper oral health-care and ultimately to improve the quality of life by considering the daily number of tooth brushing, oral hygiene product use, regular dental treatments, and other medical uses.

This study investigated the relevancy between the subjective awareness and the level of knowledge of oral health by surveying oral health management behaviors of elderly citizens over 60 years old in certain areas. The survey was conducted from September 1 to December 30, 2016 among the elderly aged 60 or older in the GyeongBuk, and 442 responses were used in the data analysis. The statistical analysis methods were frequency analysis, t-test and ANOVA analysis. The subjective oral health awareness in accordance with oral health management behaviors were higher in the groups who brush their teeth better and for longer duration (p<.05), where the oral health knowledge level in accordance with oral health management behaviors were higher in the groups who received toothbrushing training (p<.05). Based on the above results, the subjective oral health awareness and the oral health knowledge level of elderly citizens should be improved through continuous educations for ideal oral health management behaviors in order to promote oral health of elderly citizens.

Objective: This systematic review aimed to provide a comparative analysis of the treatment outcomes, including hard and soft tissues, postoperative stability, temporomandibular disorders (TMD), and quality of life (QoL), in patients with facial asymmetry who underwent orthognathic surgery. Methods: The primary objective was to address the question, "How do different factors related to surgery affect the outcomes and stability of orthognathic surgery in the correction of facial asymmetry?" A meta-analysis was conducted on the outcome parameters, such as skeletal, dental, and soft tissue symmetry, TMD, QoL, and relapse, using the Hartung-Knapp-Sidik-Jonkman method for random-effects models. Subgroup analyses were conducted considering surgery-related factors such as surgical techniques (one-jaw vs. two-jaw), use of the surgery-first approach, utilization of computer simulation, and analytical methods employed to evaluate asymmetry (2D vs. 3D). Results: Forty-nine articles met the inclusion criteria. The metaanalysis demonstrated a significant improvement in the symmetry of hard and soft tissues. The subgroup analysis indicated that the treatment outcomes showed significant improvement, regardless of the factors related to surgery. Changes in TMD signs and symptoms varied according to the surgical technique used. Quality of life improved in the facial, oral, and social domains. Skeletal relapse was observed during the follow-up. Conclusions: Our findings support the positive outcomes of orthognathic surgery in the treatment of facial asymmetry in terms of skeletal and soft tissue improvements, stability, relief of TMD symptoms, and enhancement of QoL. However, most of the included studies showed a low certainty of evidence and high heterogeneity.
