The purpose of this study is to analyze the dental hygienists' overall performance in operative restoration and the clinical performance in operative restoration according to dental hygienists' career and to provide basic data for establishing the appropriate range of dental hygienists' work. Subjects of this study are 339 dental hygienists working at dental clinic and hospital nationwide, selected by their working place, career, type of clinic, and location of clinical institution. The distribution of people who responded to the survey shows that 81 belong to beginner level(less than 2 years since entering clinic), 115 intermediate level(2 to 3 years since entering clinic), 81 higher level(4 to 5 years since entering clinic) and 62 advanced level(more than 6 years since their entering clinic). In terms of the types of clinical institution, 178 belong to dental clinics and 161 belong to dental hospitals. The survey used in this study are focused on perception about clinical performance in operative dentistry and adequacy of the work. Operative dentistry consists of operative restoration and endodontic therapy. The operative restoration consists of 15 categories such as patient welcoming, examination and diagnosis, planning of treatment, anesthesia, control of moisture, cavity preparation, pulp protection, matrix band application, amalgam filling, resin filling, glass ionomer cement filling, abrasive strip removal, rubber dam removal, bite check and polishing, patient education, and arrangement. The reliability was Cronbach's Alpha .9453. SPSS 10.0 for Windows was used to analyze the responses. One way ANOVA was utilized to verify the differences in the dental hygienists' job performance in operative restoration and their job performance according to career. When significant difference was found. Duncan multi comparison post hoc was done. To sum up the results of this study, patient welcoming look the first place in the operative restoration. It was followed by patient education, examination and diagnosis, introducing treatment plan, resin filling, glass ionomer cement filling, amalgam filling, bite check and polishing, anesthesia, pulp protection, control of moisture, abrasive strip removal, cavity preparation, matrix band application, rubber dam removal, and anesthesia. In terms of the clinical performance by career, there were significant differences in 19 activities such as medical eraluation, oral examination, patient charting, intra oral readio graphs, firm developing fixing mounting, curing light gun, education of attention content after operation. Based on the results of this study, the specific range of operative restoration for dental hygienists should be focused on providing basic data for dentists' diagnosis, alleviation of fear and aching accompanied by injection and anesthesia, data providing for dentists' decision of anesthesia degree, and maximization of control of moisture.

Although intentional replantation is frequently used as a treatment modality for endodontic problems, severe periodontal involvement has usually been regarded as a contraindication. However, there are some studies suggesting that intentional replantation could be a successful treatment alternative for periodontally involved teeth. This paper reports the treatment of a tooth with severe periodontal involvement using intentional replantation. The tooth, which had had root canal therapy due to endodontic-periodontal combined lesion but showed extensive bone loss, was gently extracted and replanted after thorough debridement of the root surface. By intentional replantation, a tooth with severe periodontal involvement in this case could be preserved, without extraction, over the course of a 3-year follow-up period.

Objectives: The aim of this study was to examine the factors influencing empowerment among clinical dental hygienists. Through this study, we suggested to increase the empowerment and find concrete ways to increase the motivation and performance of individuals and organizations. Methods: A self-reported questionnaire was filled out by 202 dental hygienists of clinic from November 8 to December 10, 2018. Data were analyzed using SPSS 20.0. Independent t-test, one-way ANOVA, Scheffe's post-hoc test, and Pearson correlation coefficients were reviewed, and a multiple regression analysis was conducted. Results: Dental hygienists scored 3.33 points on empowerment. The variables that influenced clinical empowerment were job satisfaction, career, monthly income, and preventive treatment. These factors explained 32.3% of the variance in dental clinic hygienists. Conclusions: To enhance the performance of individuals and organizations through increased empowerment, dental hygienists need support to perform more diverse roles, such as providing preventive measures and oral health education, to enhance their professional self-concept and autonomy.

Background: When performing dental treatment under general anesthesia in adult patients who have difficulty cooperating due to intellectual disabilities, anesthesia induction may be difficult as well. In particular, patients who refuse to come into the dental office or sit in the dental chair may have to be forced to do so. However, for adult patients with a large physique, physical restraint may be difficult, while oral sedatives as premedication may be helpful. Here, a retrospective analysis was performed to investigate the effect of oral sedatives. Methods: A hospital-based medical information database was searched for patients who were prescribed oral midazolam or triazolam between January 2009 and December 2017. Pre-anesthesia evaluation, anesthesia, and anesthesia recovery records of all patients were analyzed, and information on disability type, reason for prescribing oral sedatives, prescribed medication and dose, cooperation level during anesthesia induction, anesthesia duration, length of recovery room stay, and complications was retrieved. Results: A total of 97 patients were identified, of whom 50 and 47 received midazolam and triazolam, respectively. The major types of disability were intellectual disabilities, autism, Down syndrome, blindness, cerebral palsy, and epilepsy. Analyses of changes in cooperation levels after drug administration showed that anesthesia induction without physical restraint was possible in 56.0% of patients in the midazolam group and in 46.8% of patients in the triazolam group (P = 0.312). Conclusions: With administration of oral midazolam or triazolam, general anesthesia induction without any physical restraint was possible in approximately 50% of patients, with no difference between the drugs.

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.

The concept of the Hospital run for medical treatment changing to the forms of theme complex hospital with design by the impact of a boutique design. Especially, this design's element emboss with strongly to form a ring around the special hospital as the dentistry, dermatology and plastic surgery, the woman hospital of a lying-in hospital etc. that is the higher value-added industrial among groups of medical, even general hospital that is not depend on the design relatively, the application of the interior design is extending farther. Also, this special hospital shape up become bigger, form a group and competition for admission to medical industry. For dentistry, the more departmentalize and definite service as implant, children dental clinic holding an absolute dominant position about management, and effective environmental exchange can be essential element for the most profits. Accordingly, In this study I would like to see about the space composition of the dentistry that changing with the times, suggest direction from now on the bigger, specialization and a characteristic of a space focused on recently dentistry project.

Purpose: The present study investigated the outcomes of a newly-developed, simple, and practical nonsurgical treatment modality suitable for most forms of intrabony defects around failing dental implants using intrasulcular delivery of chlorhexidine solution and minocycline hydrochloride (HCl). Methods: Forty-five dental implants in 20 patients diagnosed with peri-implantitis were included. At baseline and the study endpoint, the probing pocket depth (PPD), clinical attachment level (CAL), and the presence of bleeding on probing (BOP) at 6 sites around each implant were recorded. The radiographic osseous defect morphology at the mesial or distal proximal aspect of each implant was classified as 1) narrow or wide and 2) shallow or deep. For a comparative analysis of bone changes according to the defect morphology, the distance from the implant shoulder to the most coronal bone-to-implant contact point (DIB) at the mesial and distal aspects of each implant was measured at baseline and the endpoint. Patients were scheduled to visit the clinic every 2-4 weeks for intrasulcular irrigation of chlorhexidine and delivery of minocycline HCl. Results: We observed statistically significant decreases in PPD, CAL, and BOP after treatment. At the endpoint, bone levels increased in all defects, regardless of the osseous morphology of the intrabony defect. The mean DIB change in deep defects was significantly greater than that in shallow defects. Although the mean bone gain in narrow defects was greater than in wide defects, the difference was not statistically significant. Conclusions: We propose that significant and sustainable improvements in both clinical and radiographic parameters can be expected when intrabony defects around dental implants are managed through a simple nonsurgical approach involving combined intrasulcular chlorhexidine irrigation and local delivery of minocycline HCl.

Technological advances in contemporary medicine has discovered the causes of countless diseases and recorded a noticeable medical performance. As technology develops, the role of hospitals is expanding to include disease prevention of inpatients, on top of their fundamental role of treating diseases. Recently, hospitals are becoming more influential as they create environments to provide comfort and stability to patients. In this regard, contemporary hospitals are increasingly shifting their focus to create a patient-centric environment as well as develop into humanistic establishments. The same goes to dentists, as well. Since inpatients often have fear and frustration over treatment, hospitals should figure out the environmental factors that are more effective and relaxing for patients and design medical services to provide them. The patients' movement and spaces during their treatment were categorized by stages and collected for gazing information using eye tracking. It analyzed users' gaze information according to Heatmap analysis of distribution and frequency and was determined the presence or absence of stimuli on the components of space. This research is an advanced research to study and enhance treatment environment based on the analysis of patients' gazes. It attempted to create an opportunity to get closer to patient-centric environment by understanding the stimulants and obstacles and controlling the background settings.

Background: Adult patients with intellectual disabilities often strongly resist the anesthetic administration for dental procedures. This study aimed to evaluate the effect of midazolam premedication in improving the cooperation level of patients who are likely to be combative and irritated during general anesthesia (GA) induction. Methods: The patients who had received dental treatment under ambulatory GA for more than two times were included. And we selected 13 patients total that needed physical restraint or ketamine IM prior to induction at the first GA, and were prescribed midazolam tablet (7.5-15 mg) at the following GA. We reviewed pre-anesthetic records and anesthesia records, and evaluated cooperative levels of patients (4 levels scale) during anesthesia induction and recovery time retrospectively. Results: All 13 patients (Male 11, Female 2) had severe mental disabilities. The average age of the patients was 24 ${\pm}$ 7 (13-37) years and their average weight was 58 ${\pm}$ 16 (34-91) kg. At the first GA, 10 patients needed physical restraint prior to induction (level 3). And 3 patients were so poorly cooperative that the induction procedure was performed after intramuscular injection of ketamine (level 4). But after the midazolam intake, 7 patients were willing to receive the anesthetic induction (level 1, 2), and 6 patient needed physical restraint (P < 0.05). There were no statistical differences in the duration of general anesthesia and postoperative recovery. Conclusions: Oral intake of midazolam was effective in improvement of cooperation without any complications.
