This study was performed to investigate the changes of oral diet intake during the admission period and identify the factors related with nutritional status in discharging of leukemia patients. This is a retrospective cross sectional study on 46 leukemia patients receiving chemotherapy at the Catholic University of Korea Seoul St. Mary's Hospital from July to September 2009. The patients' charts were surveyed on the general characteristics and factors relating chemotherapy. The calorie count method was used to investigate diet intake during admission period. Multivariate logistic regression analysis was used to identify possible confounding factors. A p < 0.05 was considered statistically significant. The mean age was $42.8\;{\pm}\;14.6$ years and the average length of stay was $30.4\;{\pm}\;7.0$ days. The incidence of malnourished patients was 60.9% in discharging. There was a significant difference in chemotherapy sessions and chemotherapy period between well-nourished and malnourished patients. The average energy intake was 1,525.9 kcal in well-nourished patients and 1,143 kcal in malnourished patients, which was significant different. From repeated measures ANOVA test, the changes of oral intake during admission period were significant by groups. In addition, there were significant differences in oral intake according to each period between well-nourished and malnourished patients. In multivariate logistic regression analysis, both the ratio of total oral energy intake to recommended energy intake and chemotherapy sessions were significantly associated with nutritional status in discharging. The results of this study could be used to establish a protocol of nutritional management for leukemia patients receiving chemotherapy.

This study investigated the effects of Oligonol intake on cortisol, interleukin (IL)-$1{\beta}$, and IL-6 concentrations in the serum at rest and after physical exercise loading. Nineteen healthy sedentary male volunteers participated in this study. The physical characteristics of the subjects were: a mean height of $174.2{\pm}2.7$ cm, a mean weight of $74.8{\pm}3.6$ kg and a mean age of $22.8{\pm}1.3$ years. Each subject received 0.5 L water with Oligonol (100 mg/day) (n = 10) or a placebo (n = 9) daily for four weeks. The body composition, the white blood cell (WBC) and differential counts as well as the serum cortisol, IL-$1{\beta}$, and IL-6 concentrations were measured before and after Oligonol intake. The cortisol concentration and serum levels of IL-$1{\beta}$ and IL-6 after Oligonol intake were significantly decreased compared to before treatment (P < 0.01, respectively). In addition, the rate of increase of these factors after exercise was decreased compared to the placebo group. There was no change in the WBC and differential cell counts. These results suggest that oral Oligonol intake for four weeks had a significant effect on inhibition of inflammatory markers in healthy young men.

Objectives: This study aimed to examine the effects of dietary protein intake and quality on periodontal disease in Korean adults. Methods: The data used for analysis were obtained from the 7th Korean National Health and Nutrition Examination Survey (2016-2018). Data were analyzed using chi-square and t-test. Additionally, multiple logistic regression analysis was performed to assess the association between dietary protein intake and quality and periodontal disease. Statistical significance level was set at <0.05. Results: Multiple logistic regression analysis of dietary protein intake and periodontal disease in the model adjusted for socioeconomic factors showed that were significantly related to the Q1 (odds ratio [OR]: 1.18, 95% confidence interval [CI]: 1.01-1.39). However, this correlation was not significant in the model in which all variables were corrected. Moreover, analysis of the dietary protein quality and periodontal disease in model 4, which was adjusted for socioeconomic variables, showed that were significantly related to the low score (OR: 1.13, 95% CI: 1.00-1.27). Conclusions: The results showed a significant association between periodontal disease and poor intake and quality of dietary protein in the Korean adult population.

This study examined the prevalence of MIH and severity of hypomineralization exhibited by MIH-affected tooth based on the clinical examination of 950 children between age 8 and 9 in the city of Jeonju. The etiology was also studied utilizing a questionnaire on the MIH risk factors. The prevalence of MIH was 7.1%. The examined MIH-affected teeth showed statically significant difference in the degree of their hypomineralization (p < 0.05). The permanent first molar showed greater frequency of MIH compared to the permanent incisor, and the MIH code 2a and 3 were only observed in the permanent first molar (p < 0.05). From the questionnaire, showed the significant relationship between the occurrence of MIH and risk factors such as stress and antibiotics intake during pregnancy, low birth weight and events like hospital admission, frequent respiratory infection, high fever and long-term antibiotics intake within the three years of children's lives (p < 0.05). Among all the possible risk factors, the antibiotics intake during pregnancy only showed high correlation with the incidence of MIH (p < 0.05).

The objective of this study was to investigate the relationship among snack consumption patterns, Socio-Economic Status(SES) and oral health behavior in Samcheok-si children. We surveyed oral health behaviors, SES, and snack consumption patterns of children from guardians of three kindergartens in Samcheok-si. There were 148 representative samples who completed the survey sheet. Chi-square test and logistic regression were conducted by SAS 9.2 survey data analysis procedure. The result of relationship between sugar snack intake frequency and house income, and caregiver's education years were significantly different (p<.05). Also, Soda consumption frequency and mother's age, and house income were significantly different (p<.05). The relationship between toothbrushing children by caregiver and fruit consumption frequency were significantly different (p<.05). Fruit consumption and caregiver's education years were associated. Also, soda intake frequency and candy reward were associated with caregiver's age and education years respectively. We found that snack intake behavior of the Samcheok-si children was not associated with their oral health behavior.

Objectives: The aim of the study is to investigate the health belief model affecting the oral health behavior in middle and high school students. Methods: The subjects were 296 middle and high school students in Seoul, Gyeonggi and Incheon from February 15 to March 21, 2014. The students filled out the self-reported questionnaires after receiving informed consents. The instrument was adopted and revised from those of Kim & Hwang, and Choi & Joo. The questionnaire consisted of 4 questions of general characteristics, 9 questions of oral health status including subjective oral health status, frequency of tooth brushing, duration of tooth brushing, method of tooth brushing, use of oral health devices, dental clinic visit, scaling services, snack intake, and smoking. The oral health belief consisted of 25 questions including susceptibility, seriousness, barriers, benefit, and self-efficacy using Likert 5 scale. The reliability of Cronbach's alpha in the study was 0.725. Data were analyzed using SPSS ver 18.0 for frequency analysis, t-test, ANOVA, ${\chi}^2$-test, and Pearson's correlation coefficient, simple regression, and binary logistic regression. Results: Oral health beliefs of middle and high school students affected the oral health behaviors. Susceptibility, barriers and self-efficacy also influenced on the oral health behaviors. In order to provide the best oral health education, susceptibility and self-efficacy are the primary factors to increase motivation because the motivation endows the students with correction of oral health behaviors that improve the knowledge, attitudes, and decrease barriers in oral hygiene. Conclusions: It is important to correct oral health behaviors in the middle and high school students by providing the continuing and systematic oral health education.

Background: Smartphones are a modern necessity. While they are convenient to use, smartphones also have side effects such as addiction. This study assessed the relationship between smartphone use, a part of everyday life in modern society, and oral health. Methods: An analysis was conducted using 2017 Korea Youth Risk Behavior Web-based Survey data. The propensity score estimation algorithm used logistic regression and 1:1 matching algorithm using nearest-neighbor matching. After matching, a total of 15,032 participants were classified into two groups containing 7,516 teenagers each who did and did not use smartphones, respectively. Results: Comparison of oral health behaviors according to smartphone use revealed a statistically significant difference in the frequency of tooth brushing per day, use of oral hygiene products, intake of foods harmful to oral health, and experience of oral health education (p<0.05). The factors affecting oral pain experience of adolescents were examined. Compared to male participants, female participants had an odds ratio of 1.627 for oral pain (p<0.05). According to the household income level, compared to the group with higher income, the group with lower income showed higher oral pain experience (p<0.05). Oral pain experience was 1.601 times more frequent among teenagers using smartphones (p<0.05). Conclusion: The results of this study indicated that use of smartphones by adolescents affected their oral health. These findings indicate the need for improved oral health management through the use of effective school oral health programs and individual counseling by oral health professionals, promotion of information dissemination through public media, and development of prevention strategies.

In this study, the objective masticatory efficiency of two groups of temporomandibular disorder patients, pain and sound groups, was compared with that in a normal group using the MAI (mixing ability Index). The subjective chewing ability was evaluated using questionnaires, such as the Food Intake Ability Index (FIA) and Visual Analogue Scale (VAS). The Oral Health Impact Profile (OHIP)-49K of the patients was also examined to measure the oral health-related quality of life. The results were as follows: 1. The MAI, FIA and VAS in the pain group were significantly lower than in the normal and sound groups. This shows that the chewing efficiency of the pain group was lower than the normal and sound groups (P<0.05). However, there was no significant difference between the sound and normal groups. 2. The OHIP-49K for the oral health-related quality of life showed a significant increase in both the pain and sound groups compared with normal group. This means that the oral health-related quality of life was lower in both the pain and sound groups. 3. There was a correlation between the MAI, FIA and VAS (P<0.01) in all subjects (71 persons). The OHIP-49K was associated with the FIA and VAS. 4. There was a correlation between the FIA and VAS (P<0.05) in the sound group but no correlation in the other groups. 5. There was a correlation between the FIA and VAS in all groups. 6. The VAS was increased significantly in the pain group according to the level of pain reduction after treatment (P<0.05). However, there was no significant increase in the MAI, even though there was an improvement in masticatory efficiency. In addition, there was no difference in the FIA and OHIP-49K according to the level of pain reduction after treatment. In this study, it is believed that pain is a main factor decreasing the masticatory efficiency in patients with temporomandibular disorders. Moreover, TMJ sounds decrease the quality of life but do not decrease the masticatory efficiency. Therefore, it is important to control the pain in order to improve the masticatory efficiency in temporomandibular disorder patients. Moreover, managing both pain and sound can improve the quality of life.

It has been documented that SPA0355 exerts antiinflammatory effects via the inhibition of nuclear factor-kappaB activation. In present study, we investigated the inhibitory effects of SPA0355 on periodontitis in an animal model. Periodontitis was induced by ligation of the cervix of the 1st molar in the left mandible in rats. After ligature, the rats were randomly divided into four groups and topically applied with SPA0355 (0.5, 1, and 2%) or the vehicle alone once daily for 10 days. Body weight and food intake were measured daily throughout the experimental period. At day 10 post-ligature, the infiltration of inflammatory cells and distance of the cementoenamel junction (CEJ) to the alveolar bone crest (ABC) in the distal area of ligatured tooth were estimated histopathologically. No changes in body weight or food intake were found between the control and SPA0355 groups. The degree of inflammation was decreased in all three SPA0355 application groups. A decrease CEJ-ABC distance was observed in the 0.5% and 1% SPA0355 groups. These results indicate that SPA0355 inhibits the infiltration of inflammatory cells and alveolar bone resorption and suggests its potential as a therapeutic agent for periodontitis.

Purpose: This study set out to evaluate the compliance to, and efficacy of oral supplementation, using a 1.5 kcal/mL or 1 kcal/mL sip feed, in children with mild to moderate malnutrition. Methods: This was a parallel, randomized, controlled open-label trial in children aged 3 to 6 years with a weight for height Z (WHZ) score <-1 and ${\geq}-3$, who were randomized to receive a total of 600 kcal/day from either a 1.5 kcal/mL or a 1.0 kcal/mL pediatric sip feed for 28 days. Assessments included daily study product intake, body weight, tolerance and dietary intake from solid food. Results: Of 110 children recruited, 98 ($mean{\pm}standard$ deviation of age $49{\pm}7months$) completed the study. Both sip feeds were well tolerated, with high compliance ($80{\pm}24%$ and $81{\pm}22%$ of prescribed volume in 1.5 kcal/mL and 1.0 kcal/mL groups respectively, p=0.79). Both study groups gained similar weight during the 28 days intervention period ($0.42{\pm}0.40kg$ in 1.5 kcal/mL group vs. $0.49{\pm}0.49kg$ in 1.0 kcal/mL group, p=0.43). There were no significant differences between the groups in weight gain and in the change in WHZ score over the intervention period. Dietary analysis at the end of the study did not show replacement of solid food by the oral nutritional supplements. Conclusion: In children with mild to moderate malnutrition, both 1.5 kcal/mL and 1 kcal/mL pediatric sip feeds had high compliance and were well tolerated, and were equally effective in promoting weight gain in the 28 days study period.
