Objectives: This study aimed to investigate the relationship between consumption of sweet drinks and foods with accompanying oral hygiene health behaviors, and their condition of oral hygiene rural residents who are expected to have relatively poor oral hygiene compared to their urban counterparts. Methods: The 384 subjects, who are aged over 40 and have taken dental examination by dentists in health branches in 6 Myouns, Kongju city, Chungchongnamdo Province during the period between June 1st through 31st, 2004, were asked about dental health behaviors and subjective symptoms using questionnaires. Results and Conclusions: Based on dental health behavior according to sweet beverage and food, the dental health behavior was desirable in both sexes for 'almost daily drink' concerning sweet beverages and 'almost never eat' concerning sweet food, with no statistical significance. As for oral conditions, the groups who responded to 'almost daily drink/eat' for sweet beverages and food had the highest rate of non-treated teeth, lost teeth, DMFT and CPITN, with no statistical significance. Multiple logistic regression analysis with the consumption frequency of sweet foods as explanatory variables and 5 factors of oral conditions as dependent variables, revealed that there was no statistical significance in the oral conditions according to the consumption frequency of sweet drinks while, as for sweet drinks, there was a significant difference to the group who answered as 'occasional gum bleeding' in the case of 'almost daily eat.' responders(OR= 2.33, 95% CI=1.42-3.81, p<0.05).

Objectives: The purpose of this study was to investigate the factors affecting subjective oral symptoms according to the gender of youth from multi-cultural families in Korea using data from the 14th (2018) Korean Youth Health Behavior Survey. Methods: The independent variables used in this study consisted of gender and sweet drink intake. The dependent variable was experience of subjective oral symptoms. Compensation variables consisted of general characteristics of school type, academic performance, economic status, drinking status, smoking status, and number of tooth brushings day before. The subjects of the study were 835 children of multi-cultural families whose parents were foreigners. All statistical analyses were performed by complex samples cross-tabulation analysis and complex samples logistic regression analysis. Statistical analysis was performed using the PASW statistical package 21.0 (Statistical Packages for Social Science Inc., Chicago, IL, USA). A significance level of 0.05 was used for statistical significance. Results: The composite sample logistic regression analysis showed that there was a statistically significant difference between gender and intake of sweet drinks in experience of subjective oral symptoms. Conclusions: These results suggest that factors influence subjective oral symptoms in Korean multi-cultural adolescents. Therefore, I hope that they will be used as basic data for the introduction and development of a customized oral health education program for improving oral health of multi-cultural adolescents.

Objective: This study aimed to quantitatively assess the relationship of smile esthetic variables with various types of malocclusion, and identify the cephalometric factors affecting smile measurements. Methods: This retrospective study included 106 patients who were treated with retention at the orthodontic department of Taipei Medical University Hospital. Hard-tissue variables were measured using lateral cephalographic tracings, and nine smile esthetic variables were measured using facial photographs. The patients were divided into three groups according to their overjet (< 0, 0-4, and > 4 mm). An analysis of variance was conducted to compare the pretreatment cephalometric variables and smile esthetic variables among the three groups. Multiple linear regression analysis was performed to identify the cephalometric factors affecting the smile measurements in each group. Results: Except the upper midline and buccal corridor ratio, all of the smile measurements differed significantly among the three groups before orthodontic treatment. Some of the smile characteristics were correlated with the cephalometric measurements in different types of malocclusion. The overjet was the major factor influencing the smile pattern in all three types of malocclusion. Conclusions: Smile characteristics differ between different types of malocclusion; the smile may be influenced by skeletal pattern, dental procumbency, or facial type. These findings indicate that establishment of an optimal horizontal anterior teeth relationship is the key to improving the smile characteristics in different types of malocclusion.

Purpose : To compare cephalometric measurement between measuring methods in digital and conventional lateral cephalometric radiograph. Materials and Methods : Twenty digital and conventional lateral cephalometric radiographs were selected. In digital group, cephalometric measurements were performed manually using hardcopies and automatically using $V-Ceph^{TM}$ program on the monitor. In conventional group, the same measurements were performed manually on conventional films, and for automatic measurement conventional films were digitized by scanner. All measurements were performed twice by 4 observers, and 24 cephalometric variables were calculated and the time spent for each measurement was recorded. The differences in measurements data and the time spent for each measurement were compared within each group. Intra-observer and inter-observer comparisons were performed. Results : In both groups, no statistically significant difference between manual and automatic measurements was observed and most of the variables didn't show statistically significant differences between methods. The observer with less experience tended to show statistically significant differences of measurements between methods, and differences from other observers. The differences of measurements between methods in digital group were lesser than those of conventional group with statistical significance in 8 variables out of 24. With automatic method and in digital group, the spent time was shorter. Conclusion : With direct digital radiograph, automatic method using manually idenitified landmarks can be preferable in cephalometric analysis. (Korean J Oral Maxillofac Radiol 2005; 35 : 15-23)

We examined the associations between Latino cultural variables and four sexual behaviors among female adolescents of Mexican origin. Participants ages 14 to 19 (N = 153; 70% born in the U.S) completed surveys about four sexual behaviors (making out, receiving and performing oral sex, and vaginal sex) and cultural variables (nativity, language use, familism, and importance of female virginity). Findings indicated that participants who were born in the U.S. were less likely to have engaged in making out and vaginal sex than participants born in Mexico. Participants reporting stronger familism were less likely to have engaged in making out and oral sex than participants reporting less familism. For all behaviors, placing a greater value on female virginity was associated with lesser odds of engaging in that behavior. This study expands our understanding of the role of nativity and Latino values in the sexual behaviors of Mexican-origin female adolescents.

This study examines the relationship between second language use outside of class and oral proficiency development. It first identifies out-of-class activities of international graduate students in the U.S. and the average time spent speaking English in those out-of-class activities. Interviews and student self-measurements of time spent speaking English each day were used to investigate the types and quantities of out-of-class activities. In addition, two sets of student oral proficiency test scores were collected. Correlation analysis is used to find out the relationship of the variables between the most salient out-of-class activities and oral proficiency gains. The findings indicate that second language use outside of class is important for international graduate students to improve their oral proficiency. This is especially true with regularized interaction such as talking at work and the average time spent speaking in English a day outside of class. This study suggests that learners of English in an ESL environment should be encouraged to take part in out-of-class activities in addition to English use in the classroom in order for them to improve their oral proficiency.

Objective: To provide reliable prediction models based on dentoskeletal and soft tissue variables for customizing maxillary incisor positions and to optimize digitalized orthodontic treatment planning. Methods: This study included 244 Chinese women (age, 18-40 years old) with esthetic profiles after orthodontic treatment with fixed appliances (133 in group I: 1° ≤ The angle between the nasion [N]-A point [A] plane and the N-B point [B] plane [ANB] ≤ 4°; 111 in group II: 4° < ANB ≤ 7°). Dental, skeletal, and soft tissue measurements were performed on lateral cephalograms of the participants. Correlation and multiple linear regression analyses were used to determine the influence of dentoskeletal and soft tissue variables on maxillary incisor position. Results: The ideal anteroposterior position of the maxillary incisor varied between sagittal skeletal patterns. The position of the maxillary incisor correlated with the sagittal discrepancy between the maxilla and the mandible (ANB), protrusion of the midface, nasal tip projection, development of the chin, and inclination of both the maxillary and mandibular incisors. Distance from the maxillary central incisor to nasion-pogonion plane predicted using multiple linear regression analysis was accurate and could be a practical measurement in orthodontic treatment planning. Conclusions: Instead of using an average value or norm, orthodontists should customize a patient's ideal maxillary incisor position using dentoskeletal and soft tissue evaluations.

Objectives : The purpose of this study was to investigate influential factors for the use of oral hygiene supplies with a view to give the right directions for related oral health education. Methods : Subjects were recruited in dental clinics in Seoul and Gyeonggi Province. Questionnaire data were carried out from June 1 to August 31, 2012. Results : 1. The awareness towards oral hygiene supplies revealed a mean of $5.46{\pm}3.87$ out of 14 points. Familiarity with the oral hygiene supplies was $2.62{\pm}2.66$ and that of oral hygiene supplies was $2.63{\pm}1.48$. 2. A regression analysis showed that by selecting the use of oral hygiene supplies as a dependent variable and the model turned out to make an 8.1% prediction. Among the selected independent variables, familiarity with the use of oral hygiene supplies revealed a statistically significant influence on the use of oral hygiene supplies that was a dependent variable(p<0.000). Conclusions : Awareness of oral hygiene supplies didn't have a lot of impact on the use of the supplies. It is important to motivate learners to make use of oral hygiene supplies in case of oral health education.

Objectives: This study aimed to understand the effect of factors, possibilities, and desires on oral examination experience behavior of the elderly using raw data from the 2017 Community Health Survey. Methods: Hierarchical logistic regression analysis, an analysis method that controls the input order of a series of independent variables, was performed for 67,835 senior citizens aged 65 and older. Results: In terms of predisposing factors-in women, the higher the level of education, the higher the oral examination practice rate, and the lower the oral examination practice rate in divorce and bereavement among those aged 75 years or older. Regarding enabling factors, the lower the income rating, the higher the oral examination experience rate in religious and social participants as well as, leisure and charity participants, and the lower the oral examination experience rate in the natural environment. Regarding the need factors, the oral examination practice rate was high when the subjective oral health level was recognized as good. Conclusions: As a result, Anderson's model confirmed that various factors affect oral examination experience behavior, and institutional support for policy consensus is needed to promote oral examination experience behavior in older people in various directions.
