The aim of this study was to investigate clinical and cephalometric characteristics of patients with anterior open bite and mandibular condylar resorption. Total of 45 subjects were recruited from the patients who visited the Department of Oral Medicine, Kyungpook National University Hospital in 2006 for treatment of temporomandibular dysfunction. After taking patient's history concerning temporomandibular joint dysfunction, clinical examination was performed and panoramic, transcranial, and lateral cephalometric radiographs were obtained. The cephalometric data were compared to those of normal Korean population. The results were as follow: 1. Clinical characteristics 1) Female was 4.6 time more prevalent than male, and 82.2% of the subjects were in second and third decade. 2) Angle's Class I occlusal type was 51%, Class II was 29%, and Class III was 20%. 3) The mean value of the overjet and overbite were 3.2mm and -1.1mm, respectively. 4) Most of the patients had parafunctional oral habits. 2. Cephalometric characteristics 1) SNA showed no significant difference between condyle resorption and normal group. However, in female resorption group, SNB was lesser and ANB was greater than those in normal group. 2) SN-GoMe and FMA increased in resorption group. 3) Palatal plane angle did not show significant difference between resorption and normal group. 4) Total posterior facial height was significantly smaller and total anterior facial height showed no significant increase as compared with those of the normal group. 5) Mandibular body length did not show any significant difference between resorption and normal group.

Background: This study aimed at investigating the meal regularity, health, and oral health habits of single Korean households to understand the impact of these factors on the risk of metabolic syndrome, in addition to preventing and managing metabolic syndrome. Methods: Using raw data from the 8th Korea National Health and Nutrition Examination Survey (2019), 274 study subjects, aged 19 to 64, were selected primarily from single adult households. Complex sample statistical analysis was performed using the Predictive Analytics Software Statistics ver. 18.0 program. Results: Regarding the meal regularity in single-person households in Korea, the younger group outperformed the middle-aged group, and those who drank more than once a month performed better than those who drank less than once a month. In terms of oral health, regardless of the age and the income level, participants who ate three meals a day had a higher rate of speech problems and chewing difficulties than those who ate irregularly or regularly on a regular day. Factors influencing the risk of developing metabolic syndrome were age, speech problems, and frequency of toothbrushing. Compared to the younger group, there were 0.361 times more people in the middle-aged group; and compared to those without speech problems, there were 1.161 more people with speech problem. Compared to those who tooth brushed more than four times a day, there were 1.284 more people who tooth brushed 2 to 3 times a day and there were 5.673 times more people who tooth brushed less than once. Conclusion: Based on the study results, it is necessary to implement a program that can plan and apply customized management measures and prevent metabolic syndrome by improving and correcting the health and oral health behaviors of single-person households in Korea. Therefore, active mediation measures, such as support and publicity at the local or national level, should be planned.

Burning mouth syndrome is characterized by a burning sensation in oral cavity without clinical signs. There has b een no established theories about the diagnosis and treatment. The purpose of this article is to examine the clinical feature of BMS patients of Korean and to present a treatment protocol that can be helpful in clinical applications. The subjects chosen for the study were 52 patients who had visited Department of Oral Diagnosis at Yonsei University Dental Hospital and were diagnosed as BMS. We did questionnaires and precise oral exam, laboratory exam, grouping of our patients, individual treatment for the groups and classification of responses to the treatment. The following results were obtained: 1. Chief complaints were throbbing (71.2%), pricking, stinging, tingling (30.8%), burning(25a%). The tongue is the most frequently affected site (82.7%), followed by full mouth, gingiva, palate, buccal mucosa, lips, throat, labial mucosa and floor of mouth. 2. The average age of onset was 48.1 year and the male to female ratio was 1 to 3. The average duration of symptom was 11.69 months for male and 23.07 months for female. 3. 32.7% of patients had appealed continuous pain, which was the most cases. Aggravating factors were peppery food, salty food, hot food, fatigue, tension conversation, sour food, cold food and toothpaste. Reducing factors were cold food, diet, going to sleep and smoking. 4. Associated symptoms were dry mouth, other life problem, altered taste perception, bad taste, throat pain, tingle and difficulty in swallowing. 5. Most of patients had appealed that there was not associated event on onset of symptom, and the order of prevalence is as fallow; dental treatment, stress, denture wearing, an attack of a systemic disease. 92.3% of patient appealed that there was no psychological withering and 7.7% of patients appealed positively. 6. There were eight males and four females that had jobs. 7. There was no family history in 100% of patients in questions about presence of family history. 8. 96.2% of patients appealed that there was no oral habits. 13.5% of patients had dryness of oral mucosa in oral exam. A significant relation to dental prosthesis was not observable, but incidence of diseases due to stress appeared high in BMS which had the clinical characteristics as above. A group having low serum iron was 63.5% and in this group period of potential iron deficiency appeared high in incidence just before move to anemia. A group represented positive response was 38.5% in fungus study for Candida albicans. Since we can expect high treatment response by prescription of iron-contained drug and antifungal drug in these patients, diagnosing patients' condition of BMS can be achieved in more various aspects through study for serum iron and Candida albicans. Furthermore, it is expected that treatment protocol can be made.

Objectives : The purpose of this study was to examine the influential factors for the oral-health practice of adult workers and the relationship of their health-promotion life style to the factors of oral-health practice in an attempt to determine the impact of health-promotion life style. Methods : The subjects in this study were 160 workers who worked in Seoul, North-Jeolla and South-Jeolla Province, and were at the age of 20 and up. The survey was conducted from February 1 to July 20, 2011. Results : As for the relationship of the general characteristics of the workers to the factors of their health-promotion practice, gender made statistically significant differences to toothbrushing female (3.24), and there were statistically significant differences in education/concern according to more than college(2.72) scored higher academic credential(p<0.05). The group of the workers whose health-promotion life style was better in terms of all the toothbrushing(3.35), use of oral hygiene supplies(2.19), regular dental-clinic visit(2.70), dietary control(2.84) and education/concern(3.20) scored higher, and there were statistically significant differences in the factors of education/concern(p<0.05). Their health-promotion life style had an impact on regular dental-clinic visit among the factors of oral-health practice(p<0.05), and there was a positive correlation between health-promotion life style and tooth brushing, dietary control(p<0.05), regular dental-clinic visit, education and concern(p<0.01) the factors of oral-health practice. Conclusions : Workers should be stimulated to get into sound life habits to change their behavior, and they should be urged to improve their preventive health care, to get a dental checkup and ultimately to promote their health as well. Companies should take measures to accelerate the oral health promotion of workers and provide more dental checkup programs for them to be more concerned about their oral health, to promote their oral health and to maintain the best oral health.

Dental erosion is a complex disease of multifactorial etiology with high risk of loss of tooth structure, which still has not been appropriate interest. The aim of this study was to assess the prevalence and risk indicators of dental erosion in Korean school children. A cross-sectional survey was performed on 664 children aged 8~9 years. Data concerning gender, types of caregiver, dietary habits, oral hygiene habits and parental knowledge were obtained from a questionnaire, which was answered by the parents of the children. Association between erosion and the factors were statistically analyzed with chi-squared test and independent t-test at a significance level of 0.05. Dental erosion was present in 242 children. In carbonated drinks, dental erosion was significantly associated with preference, frequency of consumption and the ingestion method (p < 0.05). In fruit juices, dental erosion was significantly associated with preference and frequency of consumption (p < 0.05), but no significant associations were found with the ingestion method (p > 0.05). There were no significant associations between dental erosion and gender, type of caregiver, oral hygiene habits and parental knowledge (p > 0.05). In conclusion, it was considered that motivation to be followed by practice is important as well as education for prevention of dental erosion.

This research examined the oral environmental factors to identify the risk factors for oral bacteria detection. This study comprised of 60 office workers aged between 20 and 65 years, and was performed from January 15 to February 28, 2015. The study variables measured were the stimulated and unstimulated salivary flow rates, salivary buffering, saliva pH, dry mouth at the dorsum of the tongue and the sublingual region, halitosis, and the degree of tongue-coating as oral environmental factors. To identify the presence of oral bacteria, pathogens were detected by extracting the gDNA of the resting salivary flow rate. The risk of S.mutans detection was 15 times higher with smokers, 1.3~1.6 times higher when the resting or stimulated salivary flow rate was reduced by 1 mm. The risk of P.intermedia detection was 13 times higher in smokers, 4.3 times higher as the severity of oral dryness was lowered, and 4 times higher for adults with a tongue coating than those without. In addition, the risk of detecting TM7 was 5.5 times higher as sublingual dryness was decreased by 1mm. The oral bacterial count will be reduced considerably by smoking cessation education and habits that facilitate a salivary flow rate. Furthermore, adults with good and well-managed dental hygiene are anticipated to have less oral bacteria and fewer dental diseases.

Objectives : By analyzing the affects of the mother's oral care to the caries experiences of the elementary school children, To looking for the way to prevent dental caries in the primary school, to provide baseline data to perform the associated oral health education. Methods : Between the 3,676 children's dental check-up data and the 2,934 survey of parents from 9 elementary schools in the the Gyeonggi Province, the exactly matching data of 2,358 pairs, children versus mothers, were analyzed during the period, 2009 May 4 to July 20, By using the PASW 18(SPSS-PC 18), Frequency analysis of the collected data, and cross-analysis, ANOVA, Bonferroni post-analysis was performed. Results : The findings of the study were as follows. 1. In children, the ratio(DMF rate)of the dental caries experience in permanent teeth, appeared higher for men than women. Divided by grade level, the ratio of caries experience in the permanent teeth(DMF rate) generally appear higher in older than young. Thus between the child's gender and grade level by the ratio of caries experience in the permanent teeth(DMF rate) showed the statistically significant differences (p<0.05). 2. Between the socioeconomic characteristics of mothers and the children's level of dental caries experiences, not showed the statistically significant difference.(p>0.05). 3. The significant difference showed between the dental caries levels of the children and the mother's oral health care behavior - a toothbrush replacement period, mother's broken teeth, mothers guidances of the brushing after snacks for children(p<0.05). Conclusions : The mother's oral health attitudes and behaviors can affect to their children's oral care habits. Therefore The mother themselves should have the right proper habit of oral health care, so that in oral health care mothers should be the model for their children. Institutionally more systematic and detailed oral health educational program in conjunction with the family is needed.

Purpose: Infection with HIV-1 virus has become a critical worldwide public health problem. The oral complications of HIV infection with its progression of impairment of the host response to combat infection present unique challenges to the periodontists. Material and Methods : Medline research was carried out to find relationship of the progression of HIV infection to the occurrence of oral lesions including the HIV-related periodontal diseases. Results: The linear gingival erythema, necrotizing ulcerative periodontitis, necrotizing ulcerative gingivitis and oral candidiasis are common lesions in HIV-infected individuals. The linear gingival erythema and necrotizing ulcerative periodontitis lesions in HIV-infected subjects were found to have a similar microbiological profile. There are several general considerations in the periodontal management of the HIV-infected patient with or without periodontal disease. The altered immunity and host response in patients with HIV infection may also affect the incidence and severity of other common forms of periodontal disease not associated with HIV infection. Conclusion: Periodontal diseases in HIV-infected individuals present unique challenges in diagnosis, monitoring, treatment and maintenance. Therefore exact HIV staging, geographic location, antiviral and antimicrobial therapies and oral habits should be taken into consideration when treating HIV-infected patients.
