To evaluate the efficacy of antibiotic administration in the impacted mandibular third molar extraction the author investigated 107 patients requiring extraction of the lower third molar who visited at the Department of oral and maxillofacial Surgery, Chosun Dental Hospital and were healthy without medical problems and had no signs and symptoms of infection around the lower third molar. The patients were divided into 4 groups according to the method of antibiotics administration: 13 patients without antibiotics administration(group 1), 30 patients with only intravenous injection of $Cefazoline^{(R)}$ 2.0g 30 minutes before the procedure(group 2), 39 patients with intravenous injection of $Cefazoline^{(R)}$ 2.0g 30 minutes before the procedure and oral administration of follow-up dosages of $Augmentin^{(R)}$ for 1 day(group 3), and 25 patients with intravenous injection of $Cefazoline^{(R)}$ 2.0g 30 minutes before the procedure and oral administration of follow-up dosages of $Augmentin^{(R)}$ for 3 day(group 4). Infection rates after extraction were calculated and compared according to gender, the age of the patients, the level of impaction, and also compared between four groups. The results were as follows. 1. The overall infection rate was 8.4%. 2. The infection rate was higher in male(11.9%) than in female(4.2%), but there were statistically no significant differences between them. 3. Infection rate was lower in patients under age 30(7.2%) than in patients over age 30(12.5%), but there were statistically no significant between them. 4. Infection rate was higher in patients with complete bony impacted tooth(11.1%) than in patients with partial bony impacted tooth(6.5%), but there were statistically no significant differences between them. 5. Infection rate was 7.7% in group 1, 10.0% in group 2, 10.3% in group 3, 4.0% in group 4 and there were statistically no significant differences between groups. In summary, it is more important to extract the impacted lower third molar under aseptic condition and to minimize the injury of tissue if possible than to administer the preventive antibiotics in reducing the infection rate in healthy patients without medical problems who had no signs and symptoms of infection around the lower third molar.

Objectives : Based on data collected from patients who suffered from dental caries during the period between 1990 and 2008, the number of patients and their trends were analyzed as a source of evidence to conduct the oral health plan. Methods : A population of sample design for patient survey data was derived from computerized data saved at medical institutions accredited by National Health Insurance Corporation. Large institutions such as dental hospitals were included for the complete enumeration test, while the rest of medical institutions, for example, dental clinic, relatively small institutions, were used for the sample survey. Most of patients with dental caries were outpatients and their disease was treated at the dental hospital or dental clinic in general, therefore, main analysis was carried out at those institutions. Results : The rate of patients who suffered the dental caries has decreased to 56.8% in 2008 from 78.5% in 1990. The rate of patients who visited the dental hospital for treatment has increased to 4.8% in 2008 from 0.5% in 1990, whereas the percentage of those who visited the dental clinic has fallen to 97.9% from 99.5% during the same period. The ratio by age, in the meantime, it showed that patients aged 40s has increased to 13.5% in 2008 from 7.2% in 1990, and the number also has risen in 50s from 5.6% in 1990 to 9.9% in 2008. However, the number of children aged 0 to 9 who visited hospital for treatment of dental caries has fallen to 17.0% in 2008 from 33.9% in 1990. Conclusions : By figuring out the trends of patients with the dental caries during the period between 1990 and 2008, fundamental data for the oral health policy have been collected. As a result, the necessity of a new medical treatment system for managing the dental caries in terms of patient ages as well as the oral health policy and campaign was taken into consideration.

Obiectives : The purpose of this study was to examine the oral health knowledge and practice of elementary school children in the upper grades in a WHO healthy city for the development of oral health education programs gearing toward improving oral health care habits and oral health. The subjects in this study were 379 sixth-grade children in an elementary school in a WHO healthy city, Changwon. Methods : The questionnaire used in the study covered general characteristics with five items, oral health knowledge with 35 items and oral health care practices with 24 items. The oral health knowledge category consisted of general oral health knowledge with 13 items, knowledge on oral hygiene management with 11 items, knowledge on fluoride use with 8 items and healthy diet knowledge with 3 items. The oral health care practice category consisted of general oral health care practice with six items, practice on oral hygiene management with 11 items, practice related to fluoride use with four items, and healthy diet practice with 3 items. Results : The surveyed school children got a mean of 46.1 and 40.8 on oral health knowledge and oral health care practices, respectively out of 100 points. In the knowledge category, they scored the lowest on healthy diet knowledge with 12.6, and in the practice category, they scores the lowest on the practices related to fluoride use with 21.4. According to the regression analysis, gender had a significant impact on their oral health knowledge. The boys lagged behind the girls in that regard. Their oral health care practices were under the significant influence of knowledge level. Conclusions : Systematic education programs should be provided to prevent dental caries and promote oral health of school children, and the type of programs that stress actual oral health care is especially important.

Objectives: The purpose of this study was to apply an effective oral health promotion program and effect for underprivileged lower grade students. This study attempted to resolve some oral health inequality issues by providing underprivileged children with an oral health action program designed to promote positive oral health maintenance habits. Methods: This study was carried from May to August of 2009 with 77(control group 27 subjects, experimental group 36 subjects) elementary school students selected among first to third graders attending regional welfare center's after school program in Seoul. To the control group, conventional education methods were applied. To the experimental group, newly designed program was conducted by three project experts(1 expert, 1 dentist, 1 dental hygienist). It consisted of 5 sessions and progressed with various activities. It was focused on achieving target knowledge and changing oral health behavior. In order to evaluate the designed educational program, learners' achievement was evaluated with implementing the questionnaire and one-on-one interviews. And also the oral health improvement was evaluated based on change of Patient Hygiene Performance(PHP) index. Results: Based on the results of learners' achievement, the experimental group showed the significant increment of the oral health knowledge by the relapsed time, and it maintained after finished the program(p<0.001). The patient hygiene performance index showed not significant changed(p>0.05), but 1 month later the control group showed an increment of the PHP score, but the experimental group showed a decrement of it. Conclusions: Oral health promotion program by project approach could give a long-lasting educational effect to the children and encouraged proper oral hygiene behavioral changes.

Purpose: The aim of this study was to evaluate the effects of oral health care programs in 3 school-based oral health care center among primary schoolchildren. Methods: School-based oral health care programs included fluoride mouth rinsing, pit and fissure sealing for permanent premolars and molars, fluoride gel application and chewing of xylitol candy. All of the programs were carried out by one dental hygienist among 'D' primary schoolchildren in Daegu city under the supervision of a dentist. Baseline dental examinations were completed and preventive care was implemented for 544 children during one year. All of the children visited a school-based oral health care center every three months for a regular check-up. The final oral examination was conducted from March 15 to April 1, 2004. The data analysis data was made on the basis of SAS 8.01. Mean differences between 2003 and 2004 data were compared by paired t-test. Corresponding p-values were considered significant at values less than 0.05. Results: The DMF rate and DFT index were reduced to 8.0% and 8.4% during one year respectively, but there were no statistically significant differences. The DMF rate was significantly reduced (16.3%) after a one year program of school-based oral health care practice. The DMFT(Decay Missing Filling Tooth) index was also reduced compared to 2003 throughout the entire grade. Conclusion: School-based oral health care programs can reduce the prevalence of dental caries prevalence among schoolchildren during one year. This program also improved the oral health capacity of schoolchildren. It is recommend that the school-based oral health care program should be extended to every primary school in Korea.

Background: This study evaluated the efficacy of three intraoral topical anesthetics in reducing the injection needle prick pain from local anesthetic among children aged 7-11 years old. Methods: It is a prospective, Interventional, parallel design, single-blind, randomized clinical trial in which subjects (n=90) aged 7-11 years were included in the study based on an inclusion criteria. Subjects were divided into three groups based on computer-generated randomization with an allocation ratio of 1:1:1. Groups A, B, and C received benzocaine 20% jelly (Mucopain gel, ICPA health products Ltd, Ankleshwar, India), cetacaine anesthetic liquid (Cetylite Industries, Inc, Pennsauken, NJ), and EMLA cream (2% AstraZeneca UK Ltd, Luton, UK), respectively, according to manufacturer's instructions, for 1 minute prior to local anesthetic injection. After application of topical anesthetic agent, for all the groups, baseline pre-operative (prior to topical anesthetic administration) and post-operative scores (after local anesthetic administration) of pulse rate was recorded using Pulse oximeter (Gibson, Fingertip Pulse Oximeter, MD300C29, Beijing Choice Electronic). Peri-operative (i.e., during the administration of local anesthesia) scores were recorded using Face, Legs, Activity, Cry, Consolability (FLACC) Scale, Modified Children hospital of Eastern Ontario Pain Scale (CPS) behavior rating scale, and Faces Pain Scale (FPS-R) - Revised (For self-reported pain). Direct self-reported and physiological measures were ascertained using FPS-R - Revised and Pulse oximeter, respectively, whereas CPS and FLACC scales assessed behavioral measures. To test the mean difference between the three groups, a one way ANOVA with post hoc tests was used. For statistical significance, a two-tailed probability value of P < 0.05 was considered as significant. Results: The Cetacaine group had significantly lower pain scores for self-report (P < 0.001), behavioral, and physiological measures (P < 0.001) than the other two groups. However, there was no significant difference between the Benzocaine group and EMLA group during palatal injection prick. Conclusion: Cetacaine can be considered as an effective topical anesthetic agent compared to benzocaine 20% jelly (Mucopain gel) and EMLA cream.

This systematic review aims to determine if a single buccal infiltration (without palatal infiltration in the maxilla and Inferior Alveolar Nerve Block in the mandible) with 4% articaine can induce adequate analgesia for the extraction of primary molars (Maxillary and Mandibular) in children. PubMed, Ovid SP, and Embase were searched for studies published between January 1990 and March 2020 with the relevant MeSH terms. Titles and abstracts were screened preliminarily, followed by the full-texts of the included studies. Five articles were included for this systematic review. The outcome investigated was "Procedural pain during the extraction of primary molars after injection with single buccal infiltration of 4% articaine in comparison to single buccal infiltration, double infiltration (buccal and palatal/lingual), and inferior alveolar nerve block with 2% lignocaine." Of the five studies that evaluated subjective pain during extraction, two reported no significant difference between the articaine and lignocaine groups, and the remaining three reported lower subjective pain during extraction in the articaine group. Only two studies evaluated objective pain scores during extraction, and both studies reported lower pain scores in the articaine group. There is insufficient evidence to justify the statement that a single buccal infiltration of 4% articaine alone is sufficient for the extraction of primary molars. Further evidence is required to justify the claim that palatal infiltrations and IANB can be replaced with the use of 4% articaine single buccal infiltration for the extraction of primary molars in children.

The present study attempted to analyze the influence of the mother's demographic characteristics and knowledge on oral health as well as dental care behaviors on her practice of using dental care institutions. A self-report survey was conducted among 172 mothers of children aged 5-6 attending on three preschools located in Daegu metropolitan city. Statistical analysis was conducted using the SAS 8.01 with $X^2$-test, t-test and logistic regression. The obtained results were as follows: 1. No significant association was found among the demographic characteristics of the mother, her past experience as well as the purpose of using dental care institutions. 2. There was significant relationship between the mother's knowledge and behavior concerning oral health and her past experience of using dental care institutions; the mothers having a higher level of knowledge and who thought they themselves didn't have healthy teeth and gum tended to have more visits to dental care institutions(pE0.05). There was also significant relationship between their purpose and their actual practice of using dental care institutions: the mothers having a higher level of knowledge and who thought their own oral health was good tended to visit dental institutions more for the preventive purpose than for treatments(pE0.05). 3. As a result of logistic regression, the variables formed as models were their knowledge on oral health and their values for oral health. The standardized coefficients for the two variables were -0.19 and 0.19, respectively. For the mother's purpose of visiting dental care institutions, the variables formed as models were their knowledge on oral health and their values for oral health. The standardized coefficients for the two variables were -0.40 and -0.37, respectively. The relative contributions of the two variables to the mother's practice of using dental care institutions were on the similar level.

This study aimed to determine the fluoride intakes in 120 preschool children aged 3 to 6 residing in Jumunjin (community water fluoridation area) and Gangneung (non-fluoridation area). The parents were asked to collect 24-hour urine samples and to duplicate the samples of all the diets that their children ingested in the day of urine collection. The acid-diffusible fluoride in the food and non-carbonate beverages were isolated by the acid-diffusion technique and then measured with a fluoride electrode. The fluoride in carbonate beverages, drinking waters and urine samples were measured directly with a fluoride electrode. The geometric mean (geometric standard deviation) of daily fluoride intakes from all kinds of diet was 5.99 (2.27) $\mu$g/kg/day in the children in Gangneung and that of the children in Jumunjin was 18.36 (2.69). The amount of fluoride intake by food and drinking water in fluoridation area were significantly larger than that in non-fluoridation area but the statistical difference of fluoride intake by beverages between two areas was not observed. The GMs (GSDs) of daily fluoride excretion by urine of children in non-fluoridation area and in fluoridation area were 8.39 (1.73) and 18.62 (1.77) $\mu$g/kg/day, respectively. The correlation between fluoride intake from diet excluding beverage and urinary excretion was statistically significant. It is concluded that the amount of fluoride intake of children living in fluoridation area did not exceed the upper intake level to avoid the risk of dental fluorosis (2.2 mg/day in 4- to 8-year-olds) and urinary excretion of fluoride was good indicator of fluoride intake from diets.
