Laser means "Light amplification by stimulated emission of radiation". Laser have unique characteristics according to wavelength. Wavelenth of Waterlase is 2780nm and it can be absorbed to water and hydroxyapatite. When laser is applied to some material, its temperature goes up due to laser's energy. But in dental treatment high temperature is not good for teeth. High temperature can make dental pulp and bone necrosis. Waterlase can be absorbed to water droplet, so when it burst, it can cut soft and hard tissue without raising temperature. so it is so proper to dental treatment.

Objectives : The purpose of this study was to investigate the level of expertise and awareness of information on toothpaste in dental hygienists and to give patients information on toothpaste. Methods : The subjects was 205 dental hygienists working at dental clinic, dental hospital or college dental hospital in Seoul and Gyeonggi-do. They filled out the questionaire from 13th to 27th April, 2013. Collected data were analyzed by SPSS 21.0 program and significant level was set at p=0.05. Results : The awareness of information on toothpaste was the highest in dental hygienists having under 3 years career and working at dental clinics(p<0.001). The level of expertise on toothpaste was the highest in those having over 5 years career and working at general hospital or college dental hospital(p<0.001). In association with the effect of toothpaste(p<0.05), experienced dental hygienists had a higher knowledge(1.68 point) that those who had no experience(2.27 point). Instruction of the oral care devices included 27.5% of dental floss, 27.1% of toothbrush and 25.4% of proxabrush, and 4.9% of toothpaste. Conclusions : The results revealed that the right choice of the toothpaste would be the best prevention of dental caries and it is necessary to educate the dental hygienists for the toothpaste information.

Coagulase-negative staphylococci (CNS) have recently become the bacteria most frequently found in clinical infections. The aim of this study was to investigate the prevalence, antimicrobial susceptibilities, and molecular characteristics of CNS isolates from dental clinic environments in Busan, Korea. One hundred and fifty-four samples were collected from 10 dental clinics and dental hospitals in Busan from December 2014 to January 2015. Species were identified by matrix-assisted laser desorption/ionization–time-of-flight. Antimicrobial susceptibility was determined by disk diffusion methods. A polymerase chain reaction was performed to detect mecA, mupA gene, and SCCmec types. Of the 154 samples, 10(6.5%) isolates were identified as CNS (5 Staphylococcus epidermidis, 2 Staphylococcus capitis, 2 Staphylococcus, and 1 Staphylococcus haemolyticus). Among the 10 isolates, 6 were resistant to penicillin, 5 were resistant to gentamicin, 3 were resistant to tetracycline, and 2 were resistant to cefoxitin and erythromycin. However, clindamycin, ciprofloxacin, teicoplanin, and trimethoprim-sulfamethoxazole resistant isolates were not present. Genes encoding mecA were detected in 4 (2 S. warneri and 2 S. haemolyticus) isolates, and mupA in 1 (S. epidermidis) isolate. One methicillin-resistant CNS (S. warneri) isolate was determined as being of the SCCmec type I. It is concluded that CNS resistant to various antimicrobial agents was widely distributed in dental clinic environments in Korea.

Background: Elderly patients with progressive dementia including Alzheimer's disease (AD) are more and more often scheduled to undergo general anesthesia for various pathologies including dental problem. But, there is high risk of deterioration of underlying mental diseases and other co-morbidities. So it is important to implement preventive strategies and take adequate measures to minimize negative perioperative events in these patients. Methods: We reviewed the 17 cases of 11 patients with AD who underwent ambulatory general anesthesia for dental treatment at the clinic for the disabled in Seoul National University Dental Hospital. Results: The mean age was 68 (57-81) years. All of them were diagnosed with AD and some had hypertsnsion, bronchiectasis, urinary incontinence. For anesthesia induction, 3 cases (1 patient) was needed physical restraint, but others showed good or moderate cooperation. Drugs used for anesthesia induction was thiopental (11 cases), propofol (3 cases) and sevoflurane (3 cases). All patients received nasotracheal intubation without difficulties. Mean total anesthetic time was 3 hour 44 min ${\pm}$ 60 min and staying time at PACU was 83 ${\pm}$ 34 min. All the patients except one who showed hypertension discharged without any complication. There was no death or long term hospitalization because of severe complications. Conclusions: If general anesthesia is needed, pertinent diagnostic tests and workup about other medical problems, and appropriate anesthetic planning are essential for safety.

Purpose: The characteristics of site plan and space configuration of public dentistry through examining the public dental healthcare centers for the disabled in Korea and comparison between them are necessary for the development of planning of the dental healthcare system. This study has been started to provide basic informations such as nationwide distribution, site relationship, and space configuration for the planning of public dental hospital architecture. Methods: Literature review of publicness and public dental healthcare and investigation on current status of public dental healthcare center for the disabled in Korea have been conducted. The site plan and space configuration of eight public healthcare centers for the disabled have been analyzed. Results: The result of this study can be summarized in three points. The first one is that public dentistry in Korea are distributed public dental hospital for the disabled in Seoul and public dental healthcare centers for the disabled in eight provinces. The second one is that the types of the dental healthcare center for the disabled are divided with remodeling type which is diverted from existed dental or medical out patient clinic space or independent building type which is planned with a new and exclusive usage for the disabled. The third one is that the space configuration of dental healthcare center for the disabled is needed more required programs, larger treatment unit space, and more private clinic space than typical dental treatment plan. Implications: This study is the starting point for the research of public dentistry and it is necessary to analyze the dental prevention and dental public policy to develop the public dental healthcare system.
