Purpose : To determine wether varicella can be prevented by administration of oral acyclovir(ACV) during the incubation period of the disease. Methods : Starting 9 days after exposure to the index case in their families, ACV(40 mg/kg/day in four divided doses) was given orally to 20 exposed children for 5 days. Their clinical features was compared with those of 20 control subjects. Antibody titers to VZV were measured in both group 1 week and 4 weeks after finishing the oral ACV administration. Results : The mean age of family members with varicella(51.4 months) were significantly high compared to that of ACV prophylaxis group(28.5 months) and control group(31 months) (P<0.05). Among the 12 children with ACV prophylaxis who completed follow up blood sampling, nine children were diagnosed as VZV infection on the serologic test(75%). Among them six children showed positive VZV IgM on the first blood sample and two children showed serocoversion to positive IgM on the second test after ACV prophylaxis. One child who was negative on both IgM and IgG, showed positive IgG on the second test. The incidence of fever and severity of skin rashes were significantly low in children received oral ACV than in the control group. No or reduced number of maculopapular eruption were observed in the oral ACV group compared to multiple vesicles of the control group. Conclusion : In the present study, we observed that oral ACV prophylaxis to the family contacts is effective in reducing severity of skin lesion. It is likely that oral ACV 9 days after contact prevents or reduces blood dissemination of VZV. Little is known about clinical effect and immunity to the virus in exposed children with no varicella symptom after treatment. We propose the checking up antibody to VZV some period after oral ACV, and considering vaccination to whom with no antibody. But further more studies are needed to practical application of oral ACV for the postexposure prophylaxis of varicella.
It is improtant that performing prophylaxis procedure on an infected implant surface in order to treat peri-implantitis should not change the surface roughness and composition, so that the surface can be recovered to almost same condition as initial implant surface. This thesis, therefore, studied an effect of various oral hygiene instrument on implant surface. A surface roughness measurement instrument and an infection electron microscope were used to observe a change on surface. The purpose of this study was to obtain a clinical guidelines during implant care and peri-implantitis treatment. The result were as follows 1. Ra values (surface roughness value) at experimental group 1, group 2, and group 5 were increased significantly as compared with comparison group(p<0.05). 2. When compared experimental group 1 with each experimental groups at which prohylaxis procedure was performed, mean values of Ra at experimental group 2, group 3, group 6, and group 7 were decreased significantly(p<0.05). 3. Mean value of Ra was lowest at experimental group 2, and highest at experimental group 2, and highest at experimental group 5. 4. Analysis of SEM showed that was significant surface change at experimental group 2, group 3, group 4, group 5, and group 6 as compared with comparison group(X1000). 5. Analysis fo EDX showed that a quantity of Ti on surface for experimental group 6 was very similar to that for comparison group. In conclusion, air-powder abrasive and citric acid, plastic instrument are safe methods to use for performing prophylaxis procedure on implant care or for cleaning and sterilization process on treatment of peri-implantitis, based on the result that those method did not affect implant surface roughness and Ti composition.
Oral health projects that cater to the disabled should be more prevailing in order to ensure the maintenance and successful promotion of the oral health of disabled people. 70 public dental clinics that conducted oral health projects geared toward the disabled were examined to get a precise grip on their oral health projects. The findings of the study were as follows: 1. 31 out of 70 public dental clinics investigated(44.3%) were equipped with two or more dental hygienists who were professional human resources in charge of the oral health projects for the disabled. As for the age and disability type of the beneficiaries of the oral health projects, adolescents(74.3%) and people with mental retardation(87.1%) benefited most from the oral health projects. Concerning the most common implementation frequency of the projects, the projects were carried out once to three times a week(62.9%). 2. The most dominant oral disease treatment provided to disabled people was amalgam treatment and resin treatment(68.6%), which were the early dental caries treatment. The most common preventive treatment that was offered to improve their oral health was oral prophylaxis(82.9%). As for reform measures for the oral health projects, education of personnels in charge of the projects and their specialization(58.6%) were most emphasized. 3. Regarding factors related to the preventive oral health projects for the disabled, the implementation of oral prophylaxis and toothbrushing education was linked to the age of the beneficiaries. More oral prophylaxis was offered to teens, and more toothbrushing education was provided to preschoolers and adolescents. The age of the beneficiaries and the number of dental hygienists responsible for the projects had something to do with the application of fluorides. 4. Concerning the relationship of the preventive oral health projects for the disabled to the number of dental hygienists, one of the personnels in charge of the projects, the application of fluorides( 54.4%) and pit & fissure sealing(56.8%) were more prevalent when there were two or more dental hygienists. There was a statistically significant disparity in that regard(p<0.05). The above-mentioned findings illustrated that in order to boost the oral health of the disabled, dental hygienists who are responsible for the oral health projects for the disabled should put ceaseless efforts into fostering their professional knowledge and ability and offering quality service to disabled patients. Every public dental clinic should be equipped with plenty of professional personnels to enlarge the scope of treatment and ensure the efficiency of treatment and the preventive projects.

The purpose of this study was to provide basic information for improving oral health and dental hygiene through comprehensive dental hygiene care. The subjects in this study were 54 patients who had been treated for 4 weeks in clinic of the Dental Hygiene Department of G University under comprehensive dental hygiene control and care and measured their oral condition, intensity of oral malodor, Simplified Oral Hygiene Index (S-OHI), and Modified Personal Hygiene Performance Index (PHP-M), and surveyed their oral health behavior and oral health consciousness. The results of the study were as follows: 1. The intensity of malodor decreased by 16.49ppb from 75.33ppb on the first visit to 50.84ppb on the last visit when the comprehensive dental hygiene care had been finished. 2. As to change in S-OHI according to gender between the first visit and the last visit for comprehensive dental hygiene care, S-OHI decreased from 2.89 on the first visit to 1.16 on the last visit, and the difference was statistically highly significant. 3. As to change in PHP-M index by tooth according to gender and age between the first visit and the last visit, PHP-M index of the first 6 teeth decreased very significantly from 0.50 on the first visit to 0.34 on the last visit. 4. As a whole, significant improvement was observed in every tooth. According to gender and age, PHP-M index for Tooth No. 26, 36 and 32 decreased significantly in men and women, and those aged under 30 and those aged 30 or over, but for Tooth No. 13 and 15 and 44 it decreased significantly only in men and those aged 30 or over, and for Tooth No. 44 only in men. As presented above, the oral health behavior and oral health consciousness of the visitors to the oral prophylaxis practice room are very important, and it is necessary to enhance their interest in and knowledge of how to improve oral health. Furthermore, comprehensive dental hygiene care required for improving the visitors' oral health.

Objectives: To compare the efficacy of intravenous ondansetron (4 mg, 2 mL) and granisetron (2 mg, 2 mL) for preventing postoperative nausea and vomiting (PONV) in patients during oral and maxillofacial surgical procedures under general anesthesia. Materials and Methods: A prospective, randomized, and double blind clinical study was carried out with 60 patients undergoing oral and maxillofacial surgical procedures under general anesthesia. Patients were divided into two groups of 30 individuals each. Approximately two minutes before induction of general anesthesia, each patient received either 4 mg (2 mL) ondansetron or 2 mg (2 mL) granisetron intravenously in a double blind manner. Balanced anesthetic technique was used for all patients. Patients were assessed for episodes of nausea, retching, vomiting, and the need for rescue antiemetic at intervals of 0-2, 3, 6, 12, and 24 hours after surgery. Incidence of complete response and adverse effects were assessed at 24 hours postoperatively. Data was tabulated and subjected to statistical analysis using the chi-square test, unpaired t-test, or the Mann-Whitney U-test as appropriate. A P-value less than 0.05 was considered statistically significant. Results: There was no statistically significant difference between the two groups for incidence of PONV or the need for rescue antiemetic. Both study drugs were well tolerated with minimum adverse effects; the most common adverse effect was headache. The overall incidence of complete response in the granisetron group (86.7%) was significantly higher than the ondansetron group (60.0%). Conclusion: Granisetron at an intravenous dose of 2 mg was found to be safe, well tolerated, and more effective by increasing the incidence of complete response compared to 4 mg intravenous ondansetron when used for antiemetic prophylaxis in maxillofacial surgery patients receiving general anesthesia. Benefits of granisetron include high receptor specificity and high potency, which make it a valuable alternative to ondansetron.
The purpose of this study was to examine the satisfaction level of patients with oral health care provided by a dental hospital, especially scaling, and their oral health behavior. The subjects in this study were 263 college students who were in their 20s and selected from among patients who visited D university dental hospital in Gangwon Province during the oral prophylaxis practice of dental hygiene sophomores and juniors. The findings of the study were as follows: 1. Whether the selected students had ever had their teeth scaled was checked, and those who had outnumbered the others who hadn't. The rates of the former and latter respectively stood at 61.2 percent and 38.8 percent. Regarding places where they got their teeth scaled, the majority of the students that represented 75.2 percent did that at dental clinics. By gender, 34.4 percent of the male students did that at schools, which were larger than 11.8 percent of the female students who did. 88.2 percent of the female students did that at dental clinics, which were larger than 65.5 percent of the male students who did. Gender made significant differences to that(x2=10.79, p<.01). 2. As for satisfaction level with scaling by gender, the male students (38.7%) who had no specific idea outnumbered the female students (26.5%) who did. The female students(57.4%) who felt no pain during scaling outnumbered the male students(55.9%) who did. Gender made a significant difference to their responses. (x2=6.38, p<.05). 3. Concerning the use of oral hygiene supplies, most of the students who represented 72.2 percent had never flossed their teeth, and as many as 86.3 percent had never used a tongue cleaner. But the gaps between them and the others were not statistically significant.

To prevent musculoskeletal disorders(MSD) for dental hygiene students, who will potentially be at high risk of developing MSD while performing oral prophylaxis practice, an MSD prevention education program was designed and was offered to a group of dental hygiene students to find whether the program is effective. Before the program started and three months after the program ended, changes in the students' posture were filmed to observe them. The final subjects for analysis included 30 students in the experimental group and 41 students in the control group. To verify differences between the experimental and the control groups, repeated measures ANOVA was carried out before and after the program. After the education program, the experimental group's RULA scores for neck, left upper arm, right forearm, and wrist, RULA A score on both left and right side, RULA B score on left side, and total RULA score were significantly lowered during the operation on the upper jaw, compared with that of the control group. And, during the operation on the lower jaw, the experimental group's RULA A score, RULA B score, and total RULA score were very significantly lowered. The results of this study suggest the MSD prevention education program is effective in preventing the disorder. Thus, the program can be utilized as an education program for preventing MSDs during dental hygiene students' oral prophylaxis practice and clinical practice.
Background: The purpose of this systematic review was to investigate the effects of topical fluoride gel application on dental caries prevention in the permanent teeth of children and adolescents. Methods: We searched the EMBASE, PubMed, and Cochrane Library databases for randomized controlled trials (RCTs) assessing the effects of self-applied or professionally applied topical fluoride gels in patients <18 years of age; the search was completed on April 1, 2018. All included trials involved an experimental group (fluoride gel application) and a control group (placebo or no treatment). The outcome measures were the D(M)FS and D(M)FT indices, which were compared between the two groups. Review Manager software was used for quantitative synthesis of the final selected articles, and a forest plot was generated via a meta-analysis conducted using a random effects model. Results: The results showed that the D(M)FS and D(M)FT indices were lower in the fluoride application group than in the control group, thus indicating that fluoride gel application was effective in dental caries prevention. We also performed a subgroup analysis to determine whether the effects of fluoride application differed if patients received oral prophylaxis (self or professional) before fluoride gel application. Therefore, the two groups showed slightly larger differences when studies without oral prophylaxis before fluoride gel application were considered; however, the difference was not statistically significant. Conclusion: These findings should be utilized to raise awareness about the caries-prevention effects of topical fluoride application among patients and guardians. Further RCTs should evaluate the effects of fluoride application with or without preceding oral prophylaxis, and appropriate fluoride application guidelines should be developed to maximize the effects of fluoride application in clinical practice.
In order to develop the school dental health care in rural area, the author collected data about the population of all 6-17 year students living in Young dong-gun county, and Surveyed their dental health cares during one year of 1982. From the collected data, several dental health indices such as percentage of students of all population, percentage of students who visited dentists once or more during one year, average annual dentist visit and average annual dental treatment case were calculated and discussed. The obtained results were as follows; 1. The percentage of students of all population in Young dong-gun county was 29.65%. 2. The percentage of students who visited dentists once or more during one year was 4.67%. 3. The average annual dentist visit per student was 0.11. 4. The average annual dental treatment case per student was 0.16. 5. The oral examination case was 0.05, intraoral radiograph 0.01, oral prophylaxis 0.00, filling of dental carious lesion 0.02, pulp treatment 0.02, extraction of teeth 0.04, and others 0.02 annually in the average. In comparison with detectable need for dental treatment cases, oral prophylaxis was not supplied at all, filling of dental carious lesion was supplied about 1% and extraction of teeth was supplied about 10% of detectable need. 6. It was recommended that school incremental dental care project should be developed for school dental health programme in order to supply all of the detectable need for dental treatment.
