Objectives : The purpose of this study to provide preliminary data to effective halitosis control. Methods : A survey was carried out the self-perception of causative factors of halitosis in 98 female college students in Chungnam province. In addition, the levels of oral gas and breath gas were measured by use of the B&B checker, and an analysis was made of the correlation between halitosis and obsessive-compulsive disorder (OCD). Results : 1. Subjective halitosis awareness degree different degree of dryness, 'None', 'some', 'little' people who feel as the 'little fly' (68%), 78.3%, 70% was higher (p<0.05), halitosis interest 'very worried', 'worry', 'normal' person with a' not at all 'to 58.3% higher (p<0.01). 2. In regard to OCD severity, 49.0%, 34.7% and 16.3% were found to be mild, moderate and severe respectively. Halitosis tended to be severe in proportion to OCD severity, which was statistically significant (p<0.05). 3. Oral gas had a positively correlation with breath gas (r=0.329, p<0.01), but had a negative one with OCD severity (r=0.204, p<0.05). Conclusions : Symptoms of oral dryness and halitosis interest were associated with self-perception of halitosis. The levels of oral gas and breath gas were in inverse proportion to OCD severity. Hereat, it needs to analyze psychogenic factors properly as regards the diagnosis or treatment of halitosis.

가철성 보철물에서는 교합을 어떻게 형성하느냐에 따라 의치에 가해지는 힘의 크기가 결정되고 그에 따라 의치의 안정에도 영향을 미친다. 즉, 의치에 가해지는 외력이 의치의 유지력보다 크면 의치가 불안정해지지만 가해지는 이탈력을 줄여서 의치의 유지력보다 작아지도록 하면 의치의 안정을 얻을 수 있다. 그러므로 주의 깊은 검사와 진단과정을 통해 환자에게 적절한 교합을 설계하는 것은 의치 성공의 중요한 기준인 안정에 필수적이다.

Purpose: To evaluate the performance of the LOGICON Caries Detector using RVG-4 and RVG-ui sensors, by comparing results of each detector to the results of clinical and histological examinations. Materials and Methods : Pairs of extracted teeth were radiographed, and a total of 57 proximal surfaces, which included both carious and non-carious situations, were analyzed. The RVG-4 produced 8-bit images, while the RVG-ui unit produced 12-bit images, which were taken in the high sensitivity mode. The images produced by the LOGICON were evaluated by a trained observer using both automated and manual caries detection software modes. Ground sections of the teeth established the actual absence or existence of caries. Results: LOGIC ON-aided caries detection and depth discrimination of the RVG-4 and RVG-ui sensors were equally inconsistent irrespective of whether the LOGIC ON software was set to the automated or manual mode. Sensitivity ranged from 50% to 57% for caries penetration of the enamel-dentin junction. Conclusion: Care needs to be taken when using LOGIC ON in conjunction with RVG images as an adjunct for treatment planning dental caries. Even when applied by a trained observer, substantial discrepancies exist between the results of the LOGIC ON software-guided evalutations using RVG images and histologic examination.

Purpose: This study was performed to survey the incidence and imaging characteristics of the antral exostoses in a Korean population. Materials and methods: The cone-beam computed tomographic images of 5,268 patients were reviewed for the presence of antral exostoses. Incidence, location, shape, structure and dimension were evaluated. Gender and side difference were analyzed by chi-squared test. Results: Ninety eight antral exostoses were found in 78 (1.5%) out of 5,268 patients. Gender and sides showed no statistically significant differences. Antral exostoses was often found in the lateral wall and floor of the maxillary sinus, accounting for 58.2% and 38.8% of the exostoses, respectively. Most exostoses had broad base and were composed of spongy bone surrounded by compact bone. The mean dimension was 9.1(W)*4.9(D)*5.3(H) mm. Conclusion: Antral exostoses is not uncommon in a Korean population. The identification of antral exostoses is clinically significant to avoid unnecessary examination and treatment. It also needs to be examined carefully in the implant planning or sinus lift procedure.

The purpose of this study was to examine the influence of oral health education experience on needs for oral health education in children and adolescents in elementary and secondary schools. A self-administered survey was conducted on the students in elementary, middle and high schools located in the city of Mokpo, South Jeolla Province, from October 1 to 31, 2018. The data that were collected from 327 students were analyzed by SPSS 21.0. Statistical data on frequency, percentage, mean and standard deviation were obtained, and t-test, one-way ANOVA, correlation analysis and logistic regression analysis were carried out. The findings of the study were as follows: First, the subjects got 2.25 on a three-point scale in self-rated oral health status. This score was above average, which indicated that the students thought they were in good oral health. As for problems with oral health, dental caries was given the highest score of 2.48 on a five-point scale, followed by oral malodor with 2.35. Second, the students who experienced oral health education accounted for 69.1 percent, and the students who felt the need for this education represented 82.6 percent. As for educational content desired, the biggest group of 57.8 percent hoped to learn about how to prevent and manage dental caries, and the second largest group of 17 percent wanted to learn about how to take care of oral health during orthodontic treatment. Third, as a result of investigating the state of oral health education by the grade of school, the elementary school students had more oral health education experience than the middle and high school students, and the middle school students placed the most importance on the necessity of oral health education. The differences were statistically significant. Fourth, as a result of analyzing the correlation between oral health education experience and the necessity of oral health education, the students who had more oral health education experience asked more for this education, which implies that there was a statistically significant positive correlation. The findings of the study ascertained that oral health education should be provided for students in childhood and adolescence to boost the level of their oral health knowledge and change their oral health attitude in a positive manner. If oral health practice programs that connect schools, local communities and families with one another are developed to guide the oral health behaviors of teenagers in the right direction, it will make a contribution to the promotion of oral health.
