This study aimed to assess and compare the immune response in beagle dogs following the oral administration of a 5% propolis liquid concentrate and a 1:1 mixture of propolis and wet pet food. To assess the immune response, cell counting kit assays, cytokine enzyme-linked immunosorbent assay for TNF-alpha, IFN-gamma, and IL-1 beta, and flow cytometry were conducted. Propolis was administered at a concentration of 5% and a dosage of 20 g, with the beagles monitored over 8 weeks. Three beagles served as controls, while four beagles each were assigned to the propolis-only group and the propolis and feed mixture group. The results demonstrated that, regardless of its form, propolis enhanced immune responses in beagles. These findings suggest that administering of a mixture of propolis and wet pet food may increase the palatability of propolis for beagle dogs while maintaining its immune-enhancing effects.

A tracheostomy tube serves as airway management for patients whose respiration is impeded due to inflammation, tumor, or traumatic events. If the patients who have tracheostomy tube, visit dental clinic for dental treatments, we should consider the underlying general condition of patients and then make treatment plans according to their state. A 22-Year old male patient, who had tracheostomy tube on his neck, came to our department for comprehensive dental treatment. Mild mental retardation was observed and he was taking anti-convulsant drugs for the prevention of epileptic seizure. Multiple advanced dental caries, hopeless teeth, and impacted third molars were also observed by clinical and radiographic examination. Due to the risk of epileptic seizure and low cooperativity to tolerate the treatment, general anesthesia was recommended by physician, and the anti-convulsant drug was administrated during procedure. In this case, we aimed to report the multidisciplinary approach for the dental treatment of patient having a tracheostomy tube.

Background: Dental caries is one of several prevalent oral diseases caused by dental plaque biofilms. This study evaluated the anti-cariogenic effects of a bamboo salt (BS) and sodium fluoride (NaF) mixture on oral bacteria. Methods: The effects of several mixtures of NaF and BS on acid production, growth, and adhesion to glass beads of Streptococcus mutans, and their anti-cariogenic properties were investigated. The growth of S. mutans was measured according to optical density at 3, 6, 9, 12, 15, 18, and 24 hours after treatment using spectrophotometry at a wavelength of 600 nm, while pH was measured using a pH meter. Adhesion of S. mutans was measured according to the weight of glass beads from each group before and after incubation. Gene expression was measured using real-time polymerase chain reaction. Acid production and growth patterns of S. mutans were compared using repeated measures analysis of variance, followed by Scheffe's post-hoc test. The Kruskal-Wallis test was used to compare adhesion, followed by the Mann-Whitney test. Gene expression in the experimental and control samples was compared using the Student's t-test. Results: Growth, acid production, and adhesion of S. mutans were inhibited in all experimental groups. Expression of gft and fructosyltransferase in S. mutans was inhibited in all groups. A mixture of NaF and BS significantly reduced growth, acid production, adhesion, and gene expression of S. mutans compared with the other groups. Conclusion: Results of the present study demonstrated that a mixture of NaF and BS was useful as a mouth rinse in preventing dental caries.

Objectives: The purpose of this study was to provide the basic data necessary for the development of educational programs and materials that enable the public to have accurate knowledge and awareness of fluoride. Methods: A survey was conducted from December 2016 on 354 members of the public, aged 20 or older in South Korea to find out the effects of using toothbrush. The results can be summarized as follows. Statistical analysis of the collected data was performed using the SPSS WIN 21.0 statistical program. Results: As a result of examining the factors affecting the perception of fluoride, when fluoride education was experienced (p<0.01), fluoride was recognized (p<0.01), fluoride was experienced (p<0.05), When fluoride was considered to be good (p<0.01), the perception of fluoride was high. Conclusions: The perception of fluoride was relatively low, and the need for more active promotion of fluoride was identified. Therefore, dental medical personnel and the personnel who carry out the oral health education should make the people actively carry out education about fluoride.

Lesch-Nyhan syndrome is rare X-linked genetic disorder involving absence of the enzyme hypoxanthine guanine phosphoribosyl transferase (HGPRT) related to purine metabolism. The deficiency of HGPRT activity leads to an excesscive uric acid production and consequent hyperuricemia. It occurs almost exclusively in males, and the incidence is estimate to be 1/100,000~380,000. Clinical presentation is characterized by developmental delay, mental retardation, choreoathetosis, spastic cerebral palsy, nephrolithiasis, obstructive nephropathy and acute gouty arthritis. A characteristic feature of Lesch-Nyhan syndrome is the appearance of intractable self-mutilation behavior. Self-mutilation behavior is complicated by secondary infection and tissue loss as well as pain. The dental management of self-mutilation includes presertive methods of using appliances such as lip bumper or soft mouthguard and radical methods such as extraction of all teeth or orthognathic surgery. A case of Lesch-Nyhan syndrome patient with self-mutilation and severe lower lip injury is presented. He was treated successfully with soft mouthguard.

BACKGROUND/OBJECTIVES: Heavy alcohol consumption causes the development of alcoholic liver disease (ALD), a neglected but important public health problem. Many studies have pointed out that probiotics could improve gut health, which is also considered to be a cause of ALD. Therefore, this study screened the probiotics, Lactobacillus casei GKC1 (GKC1), L. fermentum GKF3 (GKF3), Bifidobacterium lactis GKK2 (GKK2), L. rhamnosus GKLC1 (GKLC1), L. paracasei GKS6 (GKS6), and L. plantarum GKM3 (GKM3), for their potential benefits in alleviating ALD for applications to disease prevention. SUBJECTS/METHODS: C57BL/6N mice were divided into 8 groups (n = 6 in each): normal control, positive control (alcohol-diet fed), and treatments of feeding probiotics GKC1, GKF3, GKK2, GKLC1, GKS6, and GKM3 under an oral dose 0.82 g/kg B.W. per day by oral gavage. The experiment was conducted for 8 weeks, and the concentrations of alanine aminotransferase (ALT), aspartate aminotransferase, triglyceride (TG), and total cholesterol (TC) in mice were measured. The glutathione (GSH), catalase (CAT), and histology were analyzed after sacrifice. RESULTS: The results showed a decrease in the serum ALT, liver TG, and liver TC levels in the GKS6, GKM3, and GKLC1 groups compared to the positive control. In addition, the decreasing GSH and CAT levels were inhibited in the GKS6 and GKM3 groups. The histopathological results showed that all probiotics could reduce the accumulation of liver fat. Furthermore, there was a significant difference in GKLC1 with lower stomach damage compared to the alcohol-fed mice without any addition of probiotics. CONCLUSIONS: GKLC1, GKS6, and GKM3 can be used as supplements for alleviating the development of ALD.

Background: Hepatitis B is an important public health problem as one of the leading causes of morbidity and mortality. The aim of this study was to compare the theoretical and practical knowledge levels of dental assistant students about Hepatitis B Virus. Methods: The 1st and 2nd grade students of the Oral and Dental Health program were invited to participate in the survey. Out of the 68 invited students, 61 completed the questionnaire. The average ages of the male and female students surveyed were 20.27±1.45 and 19.56±1.16, respectively. A total of 34 questions were asked, of which 15 measured basic theoretical knowledge and 19 assessed basic practical knowledge. Results: There was no statistically significant difference between the students' knowledge for each question according to their sex and grade. When the questionnaire was grouped into basic theoretical and basic practical knowledge levels, both were observed to be high. While the lowest correct answer rate was 35.00% for the questions about practical applications, it was 31.14% for the questions measuring the level of theoretical knowledge. There was no statistically significant difference when the levels of knowledge of 1st and 2nd grade students were compared. Students answered the majority of the questions correctly, and ranged between 71% and 100%. Conclusion: Students' high level of basic theoretical knowledge can be a result of their in-class education on the fundamentals. However, their knowledge about the correct approaches in practical applications indicates the beneficial role of having well-defined criteria and prevention protocols that are required in hospitals and the effectiveness of their environmental orientations.

This study's aim was to investigate their opinions to improve the educational system for dental hygienists on the basis of their duties as dental hygienists. The qualitative study was conducted among 19 dental hygienists at Daejeon, Korea from July to August 2016. Two researchers followed each subject for working hours in a day and recorded all the tasks and time to take for each task. After one day, the researchers met each subject and conducted face-to-face interviews to investigate the opinions about the dental hygiene curriculum and national board examination. The main duties recognized by more than half of the subjects were oral disease prevention including scaling and dental treatment assistance. The subjects' minority opinion about the main duties included radiography, impression taking, dental implant surgery assistance, orthodontic treatment, patient counseling, dental management and staff management, and oral health education. The most important tasks perceived by the subjects were prosthetic and implant impressions, scaling and implant surgery assistance. The subjects' minority opinion about the most important duties included patient counseling and making temporary crowns. The most difficult tasks answered by the subjects were prosthetic and implant impressions and dental implant surgery assistance. The subjects' minority opinion about it included patient counseling, scaling, and making temporary crowns. They mentioned that their curriculum in college was different from the actual work and the national board examination was not reflective of their real duties. We found out Korean dental hygienists had a lot of roles as dental assistants, dental business managers, and so on. We suggest that the law, curriculum and national board examination for dental hygienists should be revised to be able to reflect the reality of the clinical field.
