$M{\ddot{o}}nckeberg$ sclerosis is a disease of unknown etiology, characterized by dystrophic calcification within the arterial tunica media of the lower extremities leading to reduced arterial compliance. Medial calcinosis does not obstruct the lumina of the arteries, and therefore does not lead to symptoms or signs of limb or organ ischemia. $M{\ddot{o}}nckeberg$ sclerosis most commonly occurs in aged and diabetic individuals and in patients on dialysis. $M{\ddot{o}}nckeberg$ arteriosclerosis is frequently observed in the visceral arteries, and it can occur in the head and neck region as well. This report describes a remarkable case of $M{\ddot{o}}nckeberg$ arteriosclerosis in the head and neck region as detected on dental imaging studies. To the best of our knowledge, this is the first case that has been reported in which this condition presented in the facial vasculature. The aim of this report was to define the radiographic characteristics of $M{\ddot{o}}nckeberg$ arteriosclerosis in an effort to assist health care providers in diagnosing and managing this condition.

Family type is not only an important sociodemographic variable for health studies but also influences the health behavior and health condition of individuals. This study assessed a representative sample to see whether family type is associated with health behavior in Korean adults age 65 and older. This is a cross-sectional study of 9,535 Korean elderly who participated in the 2010-2012 Korean National Health and Nutrition Examination Survey. The subjects were classified as couple cohabitation, couple-offspring cohabitation, alone, or alone-offspring cohabitation. We assessed the relationship between family type and six health behaviors (smoking, high risk drinking, walking, oral examinations, health screenings, and influenza vaccinations) after controlling covariates. The "alone" classification had a significantly higher risk of no health screening, but was more likely to have an influenza vaccination than couples. Significant interactions between family type and healthy behavior were observed with oral health screening, influenza vaccination, and smoking {Odds ratio (95% confidence interval), 1.452 (1.066-1.980), 1.375 (1.083-1.747), 2.246 (1.604-3.146)}. There is a significant association between family type and healthy behaviors.

Titanium(Ti) alloys has been mostly concerned with biocompatibility, corrosion resistance, and biofunctionality. However, very little is known, about the biological effects of titanium on microorganism and in particular on the oral flora. So, the effect of titanium on the in vitro growth of oral microorganism forming dental caries was studied under either aerobic or anaerobic condition. In this study, the mostly bacterial species commonly found in dental plaque or gingival sulcus grew well in an aqueous medium containing $100{\mu}g/ml$ of titanium standard solution.

Objectives: This study aimed to assess the relationship between electric toothbrush use and the presence of community periodontal index (CPI) code calculus among Korean adults. Methods: Data from the 7th Korea National Health and Nutrition Examination Survey were analyzed. Multiple logistic regression analysis with a complex sampling design was conducted, adjusting for general characteristic factors. Analyses were performed using SPSS Statistics 29.0. Results: Among the participants, the prevalence of electric toothbrush users was 5.3%. Within this group, 4.7% had periodontal disease, whereas 5.9% did not (p=0.025). Even after adjusting for general characteristics factors in model II of electric toothbrush use, the odds ratio remained statistically significant at 0.791 (95% CI: 0.631-0.992) in all cases. Conclusions: Electric toothbrush use appears to be associated with potential benefits in managing the CPI code calculus distribution; however, evidence supporting this notion remains insufficient. The study findings suggest that these results could be a basis for future studies related to oral hygiene products and the design of oral health promotion programs.

Objectives: The aim of this study was to investigate the association between masticatory ability, oral health-related quality of life, and cognitive function in an elderly population using structural equation modeling. Methods: A total of 308 subjects, aged 65 years and over, were recruited from the senior citizen center in Daegu, South Korea and provided consent for inclusion in the study. The Korean version of the Mini-Mental State Examination (K-MMSE) was used to assess the level of cognitive function. Masticatory ability was evaluated through chewing tests, patient-perceived masticatory function and, measurement of relative occlusal forces on molar teeth using the T-Scan $III^{(R)}$ system. All data were analyzed using ${\chi}^2$ tests, t-tests, and one-way ANOVA in SPSS version 23.0 for windows. Structural equation modeling was performed using SPSS AMOS version 22.0. Results: There was a significant association between cognitive function and molar teeth occlusal force. Ability of food chewing score and patient-perceived masticatory function could affect oral health-related quality of life (P>0.05). Higher occlusal forces on molar teeth, compared to anterior teeth, positively correlated with higher cognitive function. Conclusions: These results suggest that an individual's oral health condition could affect molar teeth occlusal forces and may be related to a risk of developing dementia. Therefore, there is a need for implementing nation-wide policies to improve oral health, such as masticatory function, in the elderly population.

The purpose of this study was to analyze the dental treatment of patients with disabilities, especially according to the frequency of general anesthesia, and to propose the improvements in oral care. The subjects of the present study were 85 patients including age, sex, medical condition, dental treatment and the number of general anesthesia. The patients were divided into regular and irregular check groups according to their follow-up patterns. These two groups were compared for the frequency of general anesthesia and the type of repeated treatment. The results showed that restorative treatment was superior in numbers under first visit of general anesthesia. And more general anesthesia was performed in the irregular recall check group compared with the regular recall check group. This survey suggest that easy access to a dental clinic and the convenience of treatment is needed. On the other hand, there is a time limit on the dental care for disabilities by the dentist. Therefore oral care training program should be simultaneously provided for parents to improve the efficiency of dental care at home. In conclusion, efforts should be made for more comprehensive and effective dental care including regular recall check and preventive home care for disabilities.

Objectives : The purpose of the study is to investigate the effect of the oral hygiene care program in stroke patients. Methods : The subjects were 62 stroke patients of rehabilitation department in Youngnam University Hospital in Daegu. The study was carried out from January, 2010 to October, 2010. Intervention group was 35 and the control group was 31 patients. Tooth brushing instruction, oral health education and scaling were implemented in all patients at baseline. This program was conducted 5 times during hospitalization in intervention group. Results : In the intervention group, the mean age was 59.2 years, and women accounted for 66.7% and the control group consisted of 72.4% of women and mean age was 58.5 years. The average of the number of permanent teeth with experience of dental caries, the values of dental calculus index, plaque index, bleeding index and tooth mobility were 11.88, 11.79, 9.91, 3.16 and 1.16, respectively. The control group showed 10.21, 11.79, 9.91, 3.16 and 1.16, respectively. The proportion of subjects whose CPI was higher than 3 accounted for 97%, and the O'Leary index score was 38.6 in the intervention grou. The control group showed 100% and 38.79. Conclusions : Oral condition improved significantly in the intervention group in the third session. These findings may provide essential information for oral health program planning and implementation.

Verruco-papillary lesions (VPLs) of the oral cavity described in the literature involve a spectrum of conditions including squamous papilloma, verruca vulgaris, focal epithelial hyperplasia, condyloma, proliferative verrucous leukoplakia and verrucous carcinoma. A majority of the VPLs are slow growing, benign in nature and have a viral aetiology. Virus associated benign mucosal outgrowths are not too difficult to diagnose either clinically or by microscopy. Apart from virus-associated lesions, VPLs harboring malignant potential or behaviour such as verrucous carcinoma, proliferative verrucous leukoplakia, oral verrucous hyperplasia (OVH), oral papillary squamous cell carcinoma (PSCC) and oral conventional squamous cell carcinoma with papillary features (CSCC) need to be further clarified for better understanding of their predictable biologic behavior and appropriate treatment. Current understanding of potentially malignant VPLs is perplexing and is primarily attributed to the use of confusing and unsatisfactory terminology. In particular, the condition referred to as oral verrucous hyperplasia (OVH) poses a major diagnostic challenge. OVH represents a histopathological entity whose clinical features are not well recognised and is usually clinically indistinguishable from a verrucous carcinoma and a PSCC or a CSCC. A consensus report published by an expert working group from South Asia as an outcome of the 'First Asian Regional Meeting on the Terminology and Criteria for Verruco-papillary Lesions of the Oral Cavity' held in Kuala Lumpur, Malaysia, recognised the clinical description of these OVH as a new entity named 'Exophytic Verrucous Hyperplasia'. Previously described clinical features of OVH such as the 'blunt' or 'sharp' variants; and the 'mass' or 'plaque' variants can now collectively fall under this newly described entity. This paper discusses in detail the application of the standardized criteria guidelines of 'Exophytic Verrucous Hyperplasia' as published by the expert group which will enable clinicians and pathologists to uniformly interpret their pool of OVH cases and facilitate a better understanding of OVH malignant potential.
