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.

Dental emergency varies from toothache to trauma of oromaxillofacial area. Recently, the number of emergency cases after dental treatment is increasing because surgical treatments such as implant installation rise. Dental emergency patients have been looking for emergency room of general hospital and they could be treated only when the dentist of night duty exists. Although there are many analyses on the dental emergency patients visiting general hospitals, research on the dental treatment only has not been provided enough. We anticipated different aspects between the dental emergency patients visiting independent dental hospital and general hospitals. We analyzed dental emergency patients' chief complaints and received procedures for almost 1-year period in Won-Kwang dental hospital in Dae-jeon where there had been no dental emergency settings. With this 1574 patients' result, we tried to find appropriate treatment plans regarding dental emergency patients occurring at night and holidays.

Objectives: This study aims to provide basic data for high-quality dental services. In addition, we will promote the operation of preventive dentistry that implements preventive measures. It was conducted to study the change of patient's treatment behavior and treatment cost due to the discontinuation of preventive dentistry in university dental hospitals. Methods: This study collected data using the integrated medical information system of the C University Dental Hospital. From September 1, 2017 to August 31, 2019, data were analyzed using frequency, percentage, mean, standard deviation, chi-square test using SPSS version 24.0 statistical program, and T-test. Results: There was a significant difference in the number of preventive dental treatment cases from 58.3% of preventive dental operation periods to 41.7% of preventive dental operation periods. As a result of comparing the medical expenses, the total medical expenses during the preventive dental operation period decreased from 521,308,872 won to 379,724,995 won during the discontinuation period, 141,583,877 won. The number of medical treatments by treatment behavior decreased 3,835 (28.4%) from a total of 13,520 preventive dental operation periods to 9,685. Conclusions: This study is meaningful as the first study to confirm the change in the treatment behavior and the change in the cost of treatment due to the discontinuation of the operation of preventive dentistry at university dental hospitals. In conclusion, it is thought that there is a possibility of the lack of accessibility and the limitation of professional preventive care due to the discontinuation of preventive dentistry.

Background: In South Korea, the number of cases of dental treatment for the disabled is gradually increasing, primarily at regional dental clinics for the disabled. This study investigated pediatric patients at a treatment clinic for the disabled within a university hospital who received dental treatment under general anesthesia. This data could assist those that provide dental treatment for the disabled and guide future treatment directions and new policies. Methods: This study was a retrospective analysis of 263 cases in which patients received dental treatment under general anesthesia from January 2011 to May 2016. The variables examined were gender, age, reason for anesthesia, type of disability, time under anesthesia, duration of treatment, type of procedure, treatment details, and annual trends in the use of general anesthesia. Results: Among pediatric patients with disabilities who received dental treatment under general anesthesia, the most prevalent age group was 5-8 years old (124 patients, 47.1%), and the primary reason for administering anesthesia was dental anxiety or phobia. The mean time under anesthesia was $132.7{\pm}77.6min$, and the mean duration of treatment was $101.9{\pm}71.2min$. The most common type of treatment was restoration, accounting for 158 of the 380 treatments performed. Conclusions: Due to increasing demand, the number of cases of dental treatment performed under general anesthesia is expected to continue increasing, and it can be a useful method of treatment in patients with dental anxiety or phobia.

Background: Articaine, commercially available in South Korea from 2004, is widely being used for dental treatments. In the surgical extraction of impacted mandibular third molars, one of the most common procedures in oral and maxillofacial surgery, the anesthetic efficacy of 4% articaine and 2% lidocaine, both with 1：100,000 epinephrine, was compared. Methods: A randomized double-blind clinical trial was conducted of 80 patients for bilateral surgical extraction of mandibular third molars with informed consents. One operator carried out the routine surgical procedures using local anesthetic 4% articaine or 2% lidocaine with the same concentration of vasoconstrictor. Latency, duration of anesthesia and the amount of anesthetic solution were recorded. A visual analog scale (VAS) was used to evaluate the intraoperative pain. Results: The pain VAS scores reported similar anesthetic effect with both local anesthetics. Not in the latency of anesthesia and the amount of anesthetic solution, statistically significant difference was found in the mean duration of anesthesia. Conclusions: It was concluded that 4% articaine could offer better or at least the same clinical feasibility compared to 2% lidocaine, particularly in terms of the duration of the local anesthesia for common dental treatments.

The purpose of this study is to evaluate possibility of using indirect composite resin instead of porcelain through the measurement of shear bond strength between zirconia core and indirect composite resin under treatment of $Rocatec^{TM}$ system for improving the adhesion of indirect composite resin. 20 cylindrical zirconia core specimens were divided into 2 groups, according to zirconia surface treatment and attached materials: 1) treated with sandblast and attached with indirect composite resin, 2) treated with sandblast + $Rocatec^{TM}$ system and attached with indirect composite resin. The shear bond strength of each experimental group was measured by MTS and the changes of zirconia core surface according to surface treatments were obtained by SEM observation and measurements of surface roughness. The mean shear bond strength values are $0.55\;{\pm}\;0.11MPa$(Group SC) and $1.16\;{\pm}\;0.46MPa$(Group SRC). The mean Ra values for the surface treatments were follows: $0.39\;{\pm}\;0.13$($100{\beta}_{{\mu}m}$ sandblast) and $0.50\;{\pm}\;0.03$($100{\beta}_{{\mu}m}$ sandblast + $Rocatec^{TM}$ system). In the analysis of EDS, Si element was detected in the Group SC. The shear bond strength between zirconia core and indirect composite resin was improved significantly by using $Rocatec^{TM}$ system.

Objective: To assess the color stability and translucency of full cubic stabilized zirconia (FSZ) following orthodontic bonding with different surface treatments and coffee thermocycling (CTC). Methods: This in vitro study was conducted on 120 disc-shaped specimens of FSZ. Thirty specimens were selected as the control group and remained intact. The remaining specimens were randomly divided into three groups based on the type of surface treatment (n = 30): airborne particle abrasion (APA), silica-coating (CoJet), and carbon dioxide (CO₂) laser. After metal bracket bonding in the test groups, debonding and polishing were performed. Subsequently, all specimens underwent CTC (10,000 cycles). Color parameters, color difference (ΔE₀₀), and translucency parameter (TP) were measured three times at baseline (t0), after debonding and polishing (t1), and after CTC (t2). Data were statistically analyzed (α = 0.05). Results: Significant difference existed among the groups regarding ΔE₀₀t0t2 (p < 0.001). The APA group showed minimum (ΔE₀₀ = 1.15 ± 0.53) and the control group showed maximum (ΔE₀₀ = 0.19 ± 0.02) color stability, with no significant difference between the laser and CoJet groups (p = 0.511). The four groups were significantly different regarding ΔTPt0t2 (p < 0.001). Maximal increases in TP were noted in the CoJet (1.00 ± 0.18) and APA (1.04 ± 0.38) groups while minimal increase was recorded in the control group (0.1 ± 0.02). Conclusions: Orthodontic treatment makes zirconia restorations susceptible to discoloration and increased translucency. Nonetheless, the recorded ΔE₀₀ and ΔTP did not exceed the acceptability threshold.
