Aplastic anemia (AA) is a serious hematologic disease characterized by hypocellular bone marrow and deficient production of erythrocytes, granulocytes and platelets. Serious complications such as uncontrolled bleeding and bacteremia can occur. A case of severe AA are presented with dental considerations. A 4-year-old boy had been referred from Seoul National University Hospital for dental examination before the hematopoietic stem cell transplantation (HSCT). Treatments were planned under general anesthesia, due to the poor compliance. Following medical consult, dental treatments were performed after platelet transfusion and antibiotic prophylaxis. Postoperatively, neither significant bleeding nor complictation was observed. On the time of the treatment planning. the anesthesiologist and dentist should perform a complete hematological assessment. It is imperative not only platelet counts but also other leukocyte counts are under safe boundaries. It is mandatory to follow strict aseptic precautios for all anesthetic and surgical maneuvers. In severe thrombocytopenic patients, platelet transfusion should be considered. Also, it is recommended to establish a good oral hygiene.
The purpose of this study is to confirm the relevance between the frequency of beverage consumption and periodontal disease among Korean adults. The data used for analysis was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013-2015). The subjects were 9,042 adults aged 19 to 64. In non-smoking group, people with periodontal disease had less intake of milk, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In smoking group, people with periodontal disease had less intake of milk, liquid yogurt, carbonated beverage, and fruit juice and more intake of coffee than people without periodontal disease. In the results of verifying the correlation between periodontal disease and beverage intake in accordance with the matter of smoking after revising the socio demographic characteristics, in non-smoking group, the intake of coffee was correlated with periodontal disease. In smoking group, the intake of milk was correlated with periodontal disease. Since the intake frequency of some beverages is related to periodontal disease, there should be guidelines on beverage consumption during the periodontal disease prevention education.
This research was conducted in order to examine the effect of tooth brushing room M elementary school in Changwon-city and to provide foundation data for effective project operation afterwards. The subjects were 347 students at the M elementary school where the tooth brushing room was being taught. The control group is 289 students at J elementary school where the tooth brushing room was not being taught. Research and analysis were carried out with structured survey and examination of decayed, missing, filled teeth (DMFT) index, decayed, missing, filled tooth surface (DMFS) index and O'leary index. The data was analysed by IBM SPSS Statistics ver. 19.0 program and the result is as follows: Depends on the tooth brushing room there was difference in statistical significance in filling teeth, sealant tooth surface, filling tooth surface, missing tooth surface, DMFS, O'leary index between the subject and control group. The less the frequency of brushing, the higher the DMFT index. Negative correlation was statistically significant. With incorrect brushing method, the less the frequency, the higher the DMFS index, Negative correlation was statistically significant. When the tooth brushing room was being implemented, O'leary index became low, negative correlation was statistically significant. As a result, in order to continue the effective operation of tooth brushing room, constant supervision and monitoring on students should be acutely needed by a principal, a school nurse and teachers in charge. Also together with a systemized cooperation between a health center and a nearby university's related majors departments, the research proposes to execute constant oral health education and to expand the implementation project of the tooth brushing room at nearby elementary schools.

It is a trend that carbonated drink intake among adolescents is increasing, which makes young people more vulnerable to dental erosion. However, in Korea, public knowledge about dental erosion is very insufficient. The aim of this study was to investigate the prevalence of dental erosion and to assess its risk indicators among 13-15 years old students in Yangsan, Korea. A total of 1,371 adolescents were examined by one calibrated clinician. Dental erosion was assessed by using the Visual Erosion Dental Examination system. Correlation between their dietary habit, oral hygiene and dental erosion was assessed. The data showed that 676 (49.3%) adolescents had dental erosion. The prevalence of dental erosion was significantly higher in females than in males. The prevalence of tooth erosion in mandible is higher than in maxilla. Dental erosion was generalized to develop mostly on anterior teeth, especially lateral incisor, however, the severity score was highest in canines. Following questionnaire analysis, dental erosion was significantly associated with milk and flavored milk. No other associations were detected. The prevalence of dental erosion in this study is higher than those of previous reports. On the contrary to previously reported studies, the prevalence of dental erosion in females is higher than in males.

This study was performed to investigate of dental plaque, calculus and gingival inflammation in Beagle dogs. Forty adults Beagle dogs (28 male and 12 female) were used in this study. The dogs weighed 9.5 kg and were in good oral and systemic health as determined by physical examination, and all dogs had full and normal dentition. The dogs were given a commercial pellet feed during 2 years period. For all examination procedures, the dogs were premedicated with a subcutaneous injection of atropine sulfate (0.04 mg/kg). Anesthesia was induced and maintained by intravenous administration of ketamine (8 mg/kg) and xylazine (2 mg/kg). Dental plaque, calculus and gingival inflammation were assessed by Logan and Boyce clinical plaque index. Calculi covering the maxillary carnassial and first molar teeth were extensive and were accompanied by severe gingival inflammation and pocket formation. Calculi, accompanied by gingival inflammation, were clearly evident on buccal surfaces of other teeth. Calculi didn't showed on the lingual surfaces, but linguogingival inflammation formed in premolar teeth. Although the general pattern was clear, there was considerable variation among dogs in the rate of deposition of calculus and extend of gingival inflammation. This investigation suggest that feeding of the commercial dry food without dental hygiene increase plaque accumulation and may be a contributing factor in calculi formation and periodontal disease.

In children, during developing occlusion stage, many studies confirm a high prevalence of gingival inflammation. Prevention, early diagnosis and treatment of gingival and periodontal disease is important because by establishing excellent oral hygiene habits in children, the risk of periodontal disease can be on the decrease in adulthood. This study evaluated the gingival conditions of 50 children$(8.5{\pm}3.1years)$ and 20 $adults(26.1{\pm}3.3 years)$ receiving clinical examination and GCF test at the pediatric dentistry of Chonbuk national university hospital in Jeonju, Korea. I estimated children's and adult's gingival states by measuring gingival crevicular fluid(GCF) using Periopaper and $Periotron^{(R)}$ 8000, gingival index, plaque index, DMFT scale. The results were as follows : 1. There are no statistical differences of GCF volume among the groups of the primary dentition, tooth erupting stage, complete eruption stage(p>0.1). But mean value of GCF is highest at the tooth erupting stage. 2. Comparing with adults, children have higher mean value of GCF volume with statistical differences (p<0.001). 3. There is statistically positive relationship between volume of GCF and gingival index (GI), plaque index(PLI) in both adults and children(GI; r=0.394, PLI ; r= 0.642). 4. There is no relationship between GCF volume and dental caries, composite resin treatments (p>0.05). But There is statistically positive relationship between GCF and orthodontic treatments(p<0.001) 5. Primary dentition has higher mean value of DMFT than permanent dentition(p<0.001). But there is no statistical relationship between GCF and DMFT (p>0.1).

This study investigated the dental prosthesis condition from the sixth primitive data of Korea National Health and Nutrition Examination Survey to analyze and compare the necessity of existent dental prosthesis condition, dental bridge and dentures in order to determine the real oral health condition by educational level targeting adults aged over 20 years old. From the results, based on demographic-sociologic features, 32.2% of females were under elementary school graduation level, which was lower than males, and the educational level decreased with increasing age, and these trends were statistically significant. As for income level, 45.3% of university graduates had the highest income level and 77.4% of this age group were professionals, which was the highest percentage and was statistically significant. In terms of dental prosthesis condition according to educational level, the under elementary school graduation group had the most dental prosthesis and the greatest need for partial dentures and full dentures. As for the necessary number of fixed implants, the upper jaw had the most number of fixed implants and in the lower jaw, the under middle school graduation needed the most fixed implants.
This study aims to evaluate the impact of varying exposure to dental amalgam on urinary mercury levels in children by measuring the number of amalgam-filled teeth and the variance of mercury concentration in urine over a period of 2 years. A total of 317 (male 158, female 159) elementary school children (1st~4th graders) attending 2 schools in urban regions participated in this study. At 6-month intervals, 4 oral examinations were conducted to check any variance in the conditions of dental caries and the status of dental fillings. Also, urine tests were conducted followed by a questionnaire survey. To elucidate the factors potentially affecting the mercury concentration in urine, t-test, ANOVA, chi-square test and a mixed model were used for the analysis. Regarding the status of dental fillings in line with examination time periods, deciduous teeth had more amalgam-filled surfaces than those filled with resin, whereas permanent teeth had more resin-filled surfaces than those filled with amalgam. A significant relevance was found between the exposure to dental amalgam and urinary mercury levels. Specifically, subjects whose teeth surfaces had been filled with dental amalgam showed higher urinary mercury levels than those who had no dental amalgam fillings. Based on the analysis using the mixed model, the increase in the number of teeth surfaces filled with amalgam was found to be the factor affecting the increase in urinary mercury levels. The urinary mercury levels were found to be highly associated with the exposure to dental amalgam. The more the teeth surfaces filled with amalgam, the higher the urinary mercury levels. Hence, even a trace of dental amalgam fillings can liberate mercury, affecting the variance in the urinary mercury levels. These findings suggest that some criteria or measures should be developed to minimize the exposure to dental amalgam. Moreover, relevant further studies are warranted.
This study carried out the survey of the actual condition targeting 303 patients with execution of treatment after medical examination among patients who visited from January 2, 2008 to December 31, 2008 at dental hospital where is located in K region, and analyzed by using a program of SPSS13.0. The ratio of treatment in posterior was high with 76.9% in central incisor, 62.3% in the 1st bicuspids, and 45.3% in the first permanent molars as for health in the right teeth of maxillary, and with 77.9% in central incisor, 64.4% in the 1st bicuspids, and 47.6% in the first permanent molars as for the left teeth. In the lower jaw, the ratio of treatment in posterior was high with 92.1% in central incisor, 73.9% in the 1st bicuspids, and 42.6% in the first permanent molars as for health in the right teeth, and with 92.1% in central incisor, 75.9% in the 1st bicuspids, and 43.2% in the first permanent molars as for the left teeth. The upper left cuspid was treated in older patients by age(${\chi}^2=32.33$, p=0.000), in the more patients with high blood pressure(${\chi}^2=12.60$, p=0.000), and in case of systemic disease. The significant difference was shown(${\chi}^2=6.37$, p=0.012). The older patients led to being treated cuspid among right teeth in the lower jaw. The significant difference was shown according in the more patients with high blood pressure(${\chi}^2=8.26$, p=0.004). The left cuspid in the lower jaw was treated in the older patients by age the statistically significant difference was shown(${\chi}^2=12.10$, p=0.007).
The purpose of this study was to examine the patients' knowledge and expectation of dental implants and to provide effective consulting and accurate information on implants to them. To that end, between March 23, 2008 and June 5, 2008, patients who were visiting dental clinics (hospitals) in Seoul, Gyeonggi-do, and Incheon areas were surveyed. 84.7% of subjects said that they recognized implants, and the largest number of them (26.7%) of subjects came to know via friends. According to an analysis of subjects' knowledge of the dental implant operation, the maximum value was 4.06, and the minimum value was 3.05. The opinion value on the need to have regular examination after the implant operation was highest at 4.06. Regarding expectation over the implant operation, the maximum value was 4.42, and the minimum value was 1.78. The opinion value on considering the implant operation capability the most important was the highest at 4.42. The relationship between the knowledge of and expectation over implants was significant. By gender, females had a significantly higher level of knowledge than males. Regarding preference, females scored 3.27 points, and males scored 3.23 points. By occupation, professionals earned the highest score of 3.55 in knowledge, and professionals earned the highest score of 3.31 in expectation. According to an analysis of the relation between variables of knowledge of and variables of expectation over implants, the correlation coefficient (r) between the two factors was 0.362, indicating a positive relevancy(+)(p<.01).
