Objectives: The aim of this study was to evaluate the oral health status and behavior in Korean diabetic adults. Methods: The study subjects were 11,840 adults who participated in the fifth Korea National Health and Nutrition Examination Survey(2010-2012). Diabetic status was defined by doctors and fasting blood sugar(FBS) level. Oral health status was assessed by decayed-missing-filled teeth(DMFT), community periodontal index(CPI), periodontal disease, denture needs, limitation of oral function, and chewing difficulty. The oral health behavior was evaluated by oral examination within a year, brushing times a day, and use of auxiliary oral product. The data were analyzed by descriptive analysis, chi-square tests and multiple logistic regression analyses. Results: The prevalence rate of diabetes mellitus diagnosed by doctor and FBS was 8.3% and 10.2%, respectively. The prevalence rate of periodontitis was 25.4%. The proportions of $DMFT{\geq}20$, $CPI{\geq}3$, periodontal disease, denture needs, oral function limitation and chewing difficulty in the confirmed diabetic group by doctor were significantly higher than those of the non-diabetic group(p<0.05). In multiple logistic regression analysis, the adjusted odds ratio(aOR) for periodontal disease(aOR=1.73, 95% CI=1.41-2.12), presence of denture needs(aOR=1.40, 95% CI=1.06-1.84), limited oral function(aOR=1.43, 95% CI=1.15-1.78) and chewing difficulty(aOR=1.41 95% CI=1.13-1.77) in diabetic subjects were significantly higher than those of the non-diabetic subjects. There were similar associations between diabetes defined with FBS and oral health. In oral health behavior, diabetic subjects had significantly lower odds ratios for oral examination(aOR=0.76, 95% CI=0.60-0.98), brushing time ${\geq}2$ times(aOR=0.73, 95% CI=0.57-0.93), and auxiliary oral products(aOR=0.74, 95% CI=0.59-0.94). Conclusions: There was a significant relationship between oral health status and behavior in Korean diabetic adults. Further study is needed to evaluate the underlying mechanisms between diabetes mellitus and oral health status.

The labiomandibulotomy approch to the oral cavity and oropharygeal region was first described by Roux in 1836 and become popular for oral and oropharyngeal tumors in cases where there are no clinical and radiological signs of mandible invasion. Anterior labiomandibulotomy and swing procedure provides excellent access and facilitate a mandibular resection and subsequent repair. In last two years, 8 cases of oral and oropharyngeal tumors were treated by this approach at the Dept. of Oral & Maxillofacial Surgery, Holy Family Hospital, Catholic University of Korea. And we analyzed postoperative complications as well as functional evaluations, and the results were as follows; In 4 cases, marginal mandibulectomy were combined with labiomandibulotomy and in case of malignancies, neck dissection was performed simultaneously. In almost case, plate and miniscrew fixation was used for osteotomy sites. Histologic evaluation of the resection margins of the specimens revealed tumor free in all cases. The postoperative complications were occured in 3 cases, one case of nonunion, one case of orocutaneous fistula, and one case of wound dehisence. Occlusal stability, jaw movement and swallowing function were acceptable postoperatively in 3 months. From above results, we concluded that, this approach not only provides wide exposure, permitting radical removal of benign and malignant lesions but also preserves function with minimal complications.

Objectives: The purpose of this study is to identify the association between oral health status and pulmonary ventilatory defects. Methods: The 6th (2013-2015) National Health and Nutrition Examination Survey data was used. The study subjects were those aged 40-79 who had pulmonary function examination. Complex samples general linear model analysis, Complex samples cross-tabulation analysis, and Complex samples logistic regression analysis were conducted. Results: In terms of restrictive ventilatory defects, the study subjects (8.3%) who recognized that their oral health status was bad outnumbered those who recognized that their oral health status was good (6.1%) (p<0.05). Many of the study subjects who experienced difficulty in biting, chewing and/or speech, and who had an unhealthy periodontal had restrictive ventilatory defects and obstructive ventilatory defects (p<0.05). The association between oral health status and pulmonary ventilatory defects was analyzed. The findings showed that those who had unhealthy periodontal had a 1.33 times higher probability of pulmonary ventilatory defects than those who had a healthy periodontal (p<0.05). After taking into account general characteristics (age, sex, incomes, education, and smoking) of the subjects, the association between oral health status and pulmonary ventilatory defects was analyzed. The result found that only in cases where one experienced dental caries was an association with pulmonary ventilatory defects found. In other words, those who had dental caries showed a 0.73 times higher probability of pulmonary ventilatory defects than those who had no dental caries (p<0.05). Conclusions: Based on the findings of this research, oral health status was found to be associated with pulmonary ventilatory defects. To improve oral health, it is necessary to provide life-cycle stages based oral health education. Therefore, it is required to develop an oral health education program and develop a national oral health policy.

Objectives: To provide basic data for oral health policy by identifying the differences in oral health behaviors and conditions among middle-aged people in their 40s and 50s and relating these to their health-related quality of life, and to identify factors affecting health-related quality of life. Methods: In this study, secondary data from the National Health and Nutrition Examination Survey were used. Data were gathered from 8,127 participants, of which 2,353 were middle-aged (40-59 years old). Covariance analysis was performed using a complex sample general linear model to investigate the changes in the subjects' health-related quality of life (EQ-5D) according to their general characteristics, oral health behaviors, and oral health status. Results: Oral health behavior was not significantly related to health-related quality of life. In contrast, a higher oral health status (chewing function) was associated with better health-related quality of life. Conclusions: In conclusion, this study suggested a close relationship between oral health status (chewing function) and health-related quality of life. Therefore, it is necessary to recognize the importance of oral health in improving the health-related quality of life of middle-aged people in their 40s and 50s, as well as in informing oral health policies and preventive measures for individuals and communities.

Objective: To investigate the potential correlation between fixed orthodontic retention failure and several patient- and treatment-related factors. Methods: Patients finishing treatment with fixed appliances between 2016 and 2017 were retrospectively included in this study. Those not showing fixed retention failure were considered as control group. Patients with fixed retention failure were considered as the experimental group. Additionally, patients with failure of fixed retainers in the period of June 2019 to March 2021 were prospectively identified and included in the experimental group. The location of the first retention failure, sex, pretreatment dental occlusion, facial characteristics, posttreatment dental occlusion, treatment approach and presence of oral habits were compared between groups before and after treatment separately by using a Fisher exact test and a Mann-Whitney U test. Results: 206 patients with fixed retention failure were included, 169 in the mandibular and 74 in the maxillary jaws. Significant correlations were observed between retention failure in the mandibular jaws and mandibular arch length discrepancy (P = 0.010), post-treatment growth pattern (P = 0.041), nail biting (P < 0.001) and abnormal tongue function (P = 0.002). Retention failure in the maxillary jaws was more frequent in patients with IPR in the mandibular jaws (P = 0.005) and abnormal tongue function (P = 0.021). Conclusions: This study suggests a correlation between fixed retention failure and parafunctional habits, such as nail biting and abnormal tongue function. Prospective studies with larger study populations could further confirm these results.

Increased intracellular levels of $Ca^{2+}$ are generally thought to negatively regulate lipolysis in mature adipocytes, whereas store-operated $Ca^{2+}$ entry was recently reported to facilitate lipolysis and attenuate lipotoxicity by inducing lipophagy. Transient receptor potential mucolipin1 (TRPML1), a $Ca^{2+}$-permeable non-selective cation channel, is mainly expressed on the lysosomal membrane and plays key roles in lysosomal homeostasis and membrane trafficking. However, the roles of TRPML1 in lipolysis remains unclear. In this study, we examined whether the channel function of TRPML1 induces lipolysis in mature adipocytes. We found that treatment of mature adipocytes with ML-SA1, a specific agonist of TRPML1, solely upregulated extracellular glycerol release, but not to the same extent as isoproterenol. In addition, knockdown of TRPML1 in mature adipocytes significantly reduced autophagic flux, regardless of ML-SA1 treatment. Our findings demonstrate that the channel function of TRPML1 partially contributes to lipid metabolism and autophagic membrane trafficking, suggesting that TRPML1, particularly the channel function of TRPML1, is as therapeutic target molecule for treating obesity.
