The purpose of this study was to investigate the effects of an oral health care education program for care providers on the nutritional status of the elderly in a long-term care facility. This study was conducted at a long-term care facility located in K metropolitan city using a nonequivalent control group non-synchronized design. Fifty-four nursing home residents aged 65 years or older were assigned either to the intervention group (n=27) or the control group (n=24). The intervention group received oral health care from the care providers' intervention group, who provided oral health care for 6 weeks after 6 weeks of oral health care education. Data were collected from the control group and intervention group at the baseline 6 and 12 weeks after oral care education and were analyzed using SPSS windows 16.0. The halitosis was lower in the intervention group than the control group at 12 weeks (P<0.01). Body mass index of the intervention group at 12 weeks was higher than that at 6 weeks. Iron intake of the intervention group at 12 weeks was lower than that at baseline. At baseline, the intakes of riboflavin, folate, and potassium were lower than 75% of dietary reference intakes. In conclusion, an oral care education program for care providers was effective in improving the oral hygiene of nursing home residents, and dietary plans are needed to improve the nutritional status of them.

Objectives: This study aimed to: 1) investigate the beverage consumption pattern among Korean adults, and 2) analyze the relationship between the frequency of beverage consumption and oral health status. Methods: We used data from the 6th Korean National Health and Nutrition Examination Survey. A general linear model was employed to assess the associations between demographic factors and frequency of beverage consumption; and oral health status and the frequency of beverage consumption. Results: The beverage with the highest frequency of intake was coffee (11.5 times per week). More frequent consumptions of fruit juices and carbonated drinks were associated with higher numbers of decayed teeth. Conclusions: To improve oral health, frequent intake of acidic and sweetened beverages should be reduced, and the consumption of milk should be encouraged.

In the past gut microbiome has been the main focus of microbiome research. Studies about the microbiome inside oral cavities and other organs are underway. Studies about the relationship between noninfectious diseases and periodontal diseases, and the negative effects of harmful oral microbes on systemic health have been published in the recent past. A lot of attention is being paid towards fostering a healthy oral microbial ecosystem. This study aimed to understand the roles and effects of the microbiome inside the human body can potentially help cure various diseases including inflammatory bowel diseases with no known cure such as Crohn's disease, atopic dermatitis, obesity, cancer, diabetes, brain diseases and oral diseases. The present study examined technological trends in the correlation between the human microbiome and diseases in the human body, interactions between the human body's immunity, the metabolic system, and the microbiome, and research trends in other countries. While it has been proven that human microbiome is closely correlated with human diseases, most studies are still in the early stage of trying to compare the composition of microbiomes between health and patient groups. Since the oral environment is a dynamic environment that changes due to not only food intake but also other external factors such as lifestyle, hygiene, and drug intake, it is necessary to continue in-depth research on the microbiome composition characteristics to understand the complex functions of oral microorganisms. Analyzing the oral microbiome using computational technology may aid in disease diagnosis and prevention.

Objectives: This study aims to evaluate carbonated drinks induced dental caries with qualitative analysis and to compare with oral organic acids including lactate, acetate, propionate, formate, butyrate, pyruvate and valerate which cause caries when taking either 10% sucrose drinks or carbonated drinks. Methods: Saliva was collected from six study subjects before and after (start, 5, 10, 30 minutes) taking water intake upon (A) 10% sucrose intake, (B) 10% sucrose intake, and (C) carbonated drink intake, then they were centrifuged at 1,200 rpm followed by removing bacteria and enzymes with syringe filtering, performing a qualitative analysis with HPLC conductivity detection (GP50 gradient pump, ED 50 detector) after saliva pre-treatment under isocratic 100 mM NaOH mobile phase. Results: Higher risk of dental caries was evaluated in order of C>B>A, with the results of total oral organic acids' concentration, lactates of organic acids and organic acids produced after 5 minutes from the 3 types of drinks intake. Conclusions: Carbonated beverages were estimated to develop higher dental caries induction than beverages containing 10% sucrose because of the high organic acid concentration in the mouth after its intake.

Background: The purpose of this study was to evaluate the change of food intake after different dosages of botulinum toxin A (BTX) injection in the animal model. Additionally, the dimensional and histological change at 14 days after BTX injection was also evaluated. Methods: The comparative study was performed using the BTX injection model in rats (n = 5 for each group). Group 1 was the saline-injected group. Group 2 was the 5-unit BTX-injection group to each masseter muscle. Group 3 was the 10-unit BTX-injection group to each masseter muscle. Food intake rates and body weight were checked daily before and after BTX injection until 10 days. All animals were sacrificed at 14 days after BTX injection, and the specimens underwent hematoxylin and eosin stain and immunohistochemical staining for myosin type II (MYH2). Results: The recovery of food intake in groups 2 and 3 decreased significantly compared with group 1 from day 2 to day 7 and day 9 after injection (p < 0.05). The BTX-treated masseter muscles were significantly smaller than those in group 1 (p = 0.015). The immunohistochemical findings demonstrated that the expression of MYH2 was significantly higher in group 3 compared to groups 1 and 2 (p < 0.001). Conclusions: BTX injection to the masseter muscle in rats demonstrated short food-intake-rate reduction with recovery until 10 days after injection. The thickness of the masseter muscle and MYH2 expression were significantly changed according to the injected dose of BTX.

Background and Objectives : Globus pharyngeus is a sensation of foreign body in the throat. There are many studies evaluate relationships between globus pharyngeus and organic diseases such as laryngopharyngeal reflux, esophageal motility disorders as well as psychotic causes. But, Also many patients without etiologic causes complain of globus sensation. The authors performed a study that evaluate association between oral water intake and symptoms of globus sensation on the basis of a belief that pharyngeal dehydration due to lack of oral water intake causes globus sensation. Materials and Methods : A survey using visual analogue scale to evaluate symptoms was performed with 73 patients with globus pharyngeus. Results : Patients who drink water less than 500 mL per day (p=0.04) and less than five times per day (p=0.02) were improved after 6 months due to education and doctor's recommendation. Conclusion : Frequent and enough water intake should be recommended to resolve symptoms of globus sensation.

Objectives: Medication-related osteonecrosis of the jaw (MRONJ) is a well-known side effect of certain drugs that are used to influence bone metabolism to treat osteometabolic disease or cancers. The purpose of our study was to investigate how high-concentration and low-concentration bisphosphonate (BP) intake affects the disease severity. Materials and Methods: Data collected from the medical records of 52 patients treated with BPs, antiresorptive, antiangiogenic drugs and diagnosed with MRONJ were included in this study. Age, sex, type of systemic disease, type of drug, duration of drug treatment, jaw area with MRONJ, drug administration protocol, and MRONJ clinical and radiological findings were obtained. Patients were divided into two groups: anti-neoplastic (Group I, n=23) and anti-osteoporotic (Group II, n=29). Statistical evaluations were performed using the IBM SPSS ver. 21.0 program. Results: In both groups, more females had MRONJ. MRONJ was found in the mandibles of 30 patients (Group I, n=14; Group II, n=16). When we classified patients according to the American Association of Oral and Maxillofacial Surgeons staging system, significant differences were seen between groups (${\chi}^2=12.23$, P<0.01). More patients with advanced stage (stage 2-3) MRONJ were found in Group I (60.9%). Conclusion: According to our results, high-concentration BP intake, age and duration of drug intake increased disease severity.

A 42-year old male patient was referred to the Department of Oral Medicine, Kyungpook National University Hospital due to the chief complaint of limite mouth opening. Three years ago, the patient was diagnosed as an infarction of both cerefellar hemispheres, acute obstructive hydrocephalus and acute epidural hematoma of frontal lobe at the department of neurosurgery.Both of the infarcted cerevellar hemispheres and the epidural hematoma of frontal lobe were removed with suboccipital and frontal craniectomu. After the brain surgery jaw opening range was decreased progressively and ultimately mouth opening became almost impossible. Spasmodic and rhythmic contractions of the masseter muscles occurred intermittently during daytime as well as sleeping. Food intake was available only through Levin -tube. Actibe jaw opening exercise was prescribed with the aids of tongue blades. A moist hot pack and indomethacin phonophesis were also applied 20 minutes three times a day to decrease discomfort muscle activities. After a month of treatments, the opening range was increased to 5mm at the premolar area and oral food intake was possibel. The L-tube was removed and the patient was discharged.
