This study was performed to grasp the relation between the effect and the satisfaction of a mouth gymnastics program on the promotion of oral function of old persons. The experimental group of 47 old persons conducted a mouth gymnastics exercise two times every week for 12 weeks, while the control group of 39 old persons carrying out physical examinations. The mean salivary secretion in the experimental group was 0.075 ml and more than 0.046 ml in the control group. Maximum mouth opening in the experimental group, 4.12 cm, was higher than 3.92 cm in the control. Oral diadochokinesis in experimental and control group was 1.69 times per second and 1.65, respectively. The result of principal component analysis by Quartimax method with Kaiser normalization showed that program prevalence prediction of mouth-gymnastics exercise was high, and it is estimated that this exercise program would be more popular for health promotion of old persons. From the correlation analysis, mouth gymnastics exercise made salivary flow increase(r=.592), this exercise should be recommended actively for improving mouth health of old persons. Also more modification is required for old persons with difficulty in mouth gymnastics exercise. Some movements of the mouth gymnastics exercise need be modified, and then the exercise should be publicized as one of the ways to improve holistic health of the aged.

Introduction: Gutkha contains harmful and carcinogenic chemicals and oral cancer caused by tobacco usage has been reported as a major preventable cause of death worldwide by the World Health Organization. The Telangana state government implemented a ban on gutkha usage starting in 2013 but how effective this ban has been remains unclear. Objectives: The objective of this study was to determine the actual impact of the gutkha ban on users and vendors. Methodology: A cross-sectional study was conducted among gutkha users and tobacco vendors in Ranga Reddy district, Telangana. Based on a pilot study the sample size was determined as 368 and 384 for users and vendors respectively. Two separate questionnaires were administered to these groups. The parameters studied mainly included knowledge regarding the ban, and its impact. Results: About 49.1% of the users were aware of the ban on gutkha. Newspapers were the main source of information regarding the ban as reported by 45.3% of users. After the ban, 29.8% of gutkha users switched to other tobacco products. Awareness of health hazards and non-availability of gutkha was the most important reason stated for quitting or reducing consumption. Conclusion: The perspective of ban when visualized from the users point of view depicted a negative impact while the vendors portrayed a positive impact. Considering the addictive potential of the ingredients of gutkha, recording the effects of the ban on regular consumers and determining whether they can still obtain the products by illicit trade, would be noteworthy for implementation of strict rules.

Objective: The current study aimed to investigate the impact of high-fat diets composed of different animal and vegetable fat sources on serum metabolic health markers in Japanese quail, as well as the overall lipid content and fatty acid profiles of the edible bird tissues following significantly increased dietary lipid supplementation. Methods: Fifty seven male quail were divided into six groups and fed either a standard diet or a diet enriched with one of five different fats (22% coconut oil, lard, palm oil, soybean oil, or sunflower oil) for 12 weeks. The birds were subjected to an oral glucose tolerance test following the feeding period, after which they were euthanized and blood, liver, breast, and thigh muscle samples collected. Total fat content and fatty acid profiles of the tissue samples, as well as serum uric acid, triglyceride, cholesterol, total protein, albumin, aspartate transaminase, and total bilirubin concentrations were assessed. Results: High-fat diet feeding had no significant effects on the glucose tolerance of the birds. Dietary fatty acid profiles of the added fats were reflected in the lipid profiles of both the liver and breast and thigh muscle tissues, indicating successful transfer of dietary fatty acids to the edible bird tissues. The significantly increased level of lipid inclusion in the diets of the quail used in the present study was unsuccessful in increasing the overall lipid content of the edible bird tissues. Serum metabolic health markers in birds on the high-fat diets were not significantly different from those observed in birds on the standard diet. Conclusion: Thus, despite the various high-fat diets modifying the fatty acid profile of the birds' tissues, unlike in most mammals, the birds maintained a normal health status following consumption of the various high-fat diets.
Objective: This study aimed to investigate the effects of fluoride-containing acidic tea beverages on bovine teeth surfaces. Methods: The pH values and fluoride concentrations of 11 kinds of mineral water and 23 kinds of tea were measured. The fluoride-containing Seopyenje black tea beverages with pH 3.48 were chosen for the experimental group. Distilled water that did not contain fluoride and had the same pH value as that of the Seopyenje black teas served as the positive control. The Jeju Samdasoo mineral waters with neural pH (pH 7.52) and no fluoride were chosen as the negative control. Bovine teeth in each group were submerged for 10 minutes. Thereafter, surface microhardness of each bovine teeth was measured and the results were analyzed. Results: The pH value range was 6.94-8.09 ($mean=7.37{\pm}0.08$) for the 11 kinds of mineral water and 3.48-6.74 ($5.62{\pm}0.05$) for the 23 tea beverages. Titratable acidity of the Seopyenje black tea beverages was higher than that of the distilled water mixed with citric acid, and the pH was 5.5 and 7.0, respectively. The fluoride content of the 11 kinds of mineral water was 0-1.09 ppm ($mean=0.44{\pm}0.02ppm$) that of the 23 tea beverages was and 0-0.74 ppm ($0.64{\pm}0.06ppm$). In terms of enamel microhardness reduction of the bovine teeth, the tea beverages had the largest effects. There was no significant difference in microhardness reduction between the tea beverages and distilled water mixed with citric acid (P>0.05). Conversely, a significant difference was found between the kinds of mineral water and tea beverages, and also between mineral water and distilled water mixed with citric acid (P<0.05). Conclusions: Acidic tea beverages appeared to erode the surfaces of bovine teeth. The amount of fluoride in the tea beverages was not enough to inhibit erosion. Therefore, frequent intakes of acidic tea beverage are likely to increase erosion on the surfaces of bovine teeth, by affecting the enamel microhardness of teeth.
Objective : To investigate the prevalence of dental anomalies and to determine the associations between dental anomalies in permanent teeth Materials and methods : The samples were 1,240 patients (760 females and 480 males, mean age=15.1 years) who visited the Samsung Medical Center. Dental anomalies were diagnosed using pre-treatment dental casts, radiographs, clinical examinations, and medical/dental histories. Prevalence and association were investigated according to gender and sidedness. The Chi-square test was performed for statistical analysis. Results : The most common missing tooth was the lower lateral incisor, followed by the lower and upper second premolars. This particular dental anomaly is characteristic of the East Asian population (prevalence of congenital missing tooth=12.3%). The upper anterior area was the most frequently affected area (prevalence of supernumerary tooth was 1.5%). The presence of a supernumerary tooth was more prevalent in males than in females (p<.05, odds ratio=3.2). The most frequently affected tooth was the upper canine (prevalence of impacted tooth=4.3%). Unilateral impaction of the upper canine occurred significantly more often compared to bilateral impaction (p<.001). The prevalence of peg lateralis was 2.7%. The presence of congenital missing tooth was closely associated with peg lateralis (p<.01). If children aged 7~8 years have peg lateralis, the rest of the teeth should be checked for congenital absences. Conclusion : The early detection of dental anomalies and understanding of their associations help clinicians determine the appropriate treatment timing and methods of dealing with these anomalies.
The purpose of this study was to investigate the association between university students' dental fear and their psychological hardiness and subjective well-being, promote positive awareness of and access to dental service, and develop a plan for continuous oral health care. To collect data, convenience sampling of college students in North Jeolla Province was performed, and they were asked to complete a self-administered questionnaire from May 1 to 30, 2017. Dental fear was negatively correlated with both psychological hardiness and subjective well-being, and psychological hardiness and subjective well-being were positively correlated with each other. University students' dental fear, psychological hardiness, and subjective well-being were found to be correlated with one another; therefore, dental clinics need to apply a positive style of coping, taking into account psychological responses suitable for clinical competence on the basis of satisfactory communication, with the objective of promoting oral health.
Objective: To determine Korean facial profile preferences based on lip position as assessed by Hispanic-Americans of varying western adaptation levels and to determine whether the age and sex of the rater had any influence. Methods: For this study, 132 Hispanic-Americans and 68 Caucasians of varying age, sex and western adaptation levels volunteered to rate their preference of Korean male and female facial silhouettes having lips ranging from retruding to protruding. The Hispanic-Americans were also asked to complete a Bidimensional Acculturation Scale questionnaire to determine their western adaptation status: low-acculturated Hispanics (LAH; lesser western-adapted Hispanic participants) or high-acculturated Hispanics (HAH; higher western-adapted Hispanic participants). Results: The LAHs preferred significantly more retruded lip positions (p < 0.05) while HAHs showed some similarities with Caucasian participants in the results for the Korean male profile, even though HAHs preferred more retruded lip positions for the Korean female profile than Caucasians did (p < 0.05). The age and sex of raters did not influence the preference of facial profiles (p > 0.05). Conclusions: The results of this study suggest that Hispanic-Americans prefer a flatter Korean lip profile. It would be prudent for orthodontists to offer patients the option of altering lip profile through orthodontic and/or orthognathic surgery treatments.

Objective: The aim of this study was to compare the initial stability as insertion and removal torque and the clinical applicability of novel orthodontic zirconia micro-implants made using a powder injection molding (PIM) technique with those parameters in conventional titanium micro-implants. Methods: Sixty zirconia and 60 titanium micro-implants of similar design (diameter, 1.6 mm; length, 8.0 mm) were inserted perpendicularly in solid polyurethane foam with varying densities of 20 pounds per cubic foot (pcf), 30 pcf, and 40 pcf. Primary stability was measured as maximum insertion torque (MIT) and maximum removal torque (MRT). To investigate clinical applicability, compressive and tensile forces were recorded at 0.01, 0.02, and 0.03 mm displacement of the implants at angles of $0^{\circ}$, $10^{\circ}$, $20^{\circ}$, $30^{\circ}$, and $40^{\circ}$. The biocompatibility of zirconia micro-implants was assessed via an experimental animal study. Results: There were no statistically significant differences between zirconia micro-implants and titanium alloy implants with regard to MIT, MRT, or the amount of movement in the angulated lateral displacement test. As angulation increased, the mean compressive and tensile forces required to displace both types of micro-implants increased substantially at all distances. The average bone-to-implant contact ratio of prototype zirconia micro-implants was $56.88{\pm}6.72%$. Conclusions: Zirconia micro-implants showed initial stability and clinical applicability for diverse orthodontic treatments comparable to that of titanium micro-implants under compressive and tensile forces.

General anesthesia is an effective behavior management method for disabled patients or uncooperative children who have difficulty in cooperation. The objective of this study was to assess and analyze dental treatment under general anesthesia in department of pediatric dentistry at Pusan National University Dental Hospital for 5 years. One hundred and nine cases of general anesthesia from June 2013 to May 2018 were surveyed for this study. Patients' distribution, reasons for general anesthesia, treatment pattern, agents for general anesthesia, duration of treatment, and visiting route were assessed. The proportion of male was higher than female and age group of 5 to 9 was highest. Reasons for general anesthesia were handicapped situations with or without systemic disease(52%), operative treatment needs(13.2%), uncooperative(15%) and others(29.8%). Most used agents for general anesthesia were thiopental sodium and sevoflurane. Dental treatment under general anesthesia for handicapped and uncooperative children has been increasing. Therefore, it is important to improve the system and efficiency of general anesthesia to provide satisfactory treatment.
The objective of the current study is to provide basic data necessary for the development of systematic program that is required for the systematic occupational work training of dental hygienists who newly employed at dental hospitals or clinics. The results of the surveys were listed as in below. The survey was conducted for 175 experienced dental hygienists who are in charge of occupational work training in 6 regions(Seoul, Kyunggi, Busan, Ulsan, Kwangju, Chungnam, Kyungnam) of the country where the occupational work training for new dental hygienists is systematically operated. 1. The recognition of experienced dental hygienists for the importance of occupational work training revealed that image training was the most importantly recognized by dental hygienists in Seoul Kyunggi regions(pE.01). In case of Busan region, periodontic training and conservative dentistry training were the most importantly recognized, and customer service training was mostly highly recognized in Ulsan region(pE.01). In case of Kwangjuregion, dental health insurance claim training was recognized as most important subject, and Patient consultation training was the most importantly recognized in Chungnam region. In case of Kyungnam region. Oral surgery was recognized as the most important training subject. 2. Regard on the importance of the range of occupational work training, the experienced dental hygienists with less than 2 years of experience were found to recognize the training of greeting and naming most importantly, the dental hygienists with 2~3 years of experience most importantly recognized oral surgery, and the dental hygienists with 4~5 year of experience were found to recognize conservative training most importantly. In case of dental hygienists having 6~9 year of experience recognized periodontic and conservation trainings as the most important subjects, and the dental hygienist having more than 10 years of experience were found to recognize conservative and image trainings mostly importantly.
