It could be suggested that adult orthodontic patients may have peculiar psychological features as well as different periodontal tissue conditions compared with adolescent patients. The aims of the present investigation were to explore the relationships between psychological characteristics and treatment compliance of patient to orthodontist and assistants (dental hygienists). Two types of locus of control data (I-score, Internal locus of control score ; E-score, External locus of control score) were obtained for 312 adult patients and 765 adolescents and then analyzed in relation to their sex and treatment compliance. In general, orthodontic patients showed higher I-score trends than ordinary persons and adult patients manifested higher I-score than adolescent patients. Unlike adult patients, female adolescent patients showed higher I-score than male adolescent patients. Adult patients with higher E-score and adolescent patients with higher I-score than their counter-part subgroup were classified into more compliant group. Orthodontist performed more generous decision about patients' compliance than assistants. The results of this study also suggest that psychological survey in orthodontic field could comprise useful diagnostic criteria.

One of the most critical causes in determining the clinical outcomes of dental prostheses is the validity of models. However, studies that evaluated validity of digital models are few. The objectives of this study were to evaluate validity of edentulous digital models for full denture fabrication. Twenty stone models (edentulous model) were manufactured and scanned by dental blue light emitting diode scanner. Twenty digital models were manufactured. Six linear distances (inter-canine distance, inter-molar distance, two dental arch lengths (right, left), two diagonal of dental arch lengths (right, left) were measured for validity evaluation. The measurements of distances of stone models were used by digital vernier caliper and digital models were used by computer program. The mean${\pm}$deviations values of six distances were calculated. The means were compared by the Mann Whitney U test (${\alpha}=0.05$). All statistical analysis were performed using IBM SPSS Statistics ver. 20.0. Although digital models were smaller than stone models in six distances, there were no significant differences (p>0.05) and non exceeded the clinical acceptable range. The edentulous digital models for full denture fabrication can be considered clinically acceptable.

Objectives: This study presents the basic data necessary to explore the methods used of Korean dental hygienists to resolve oral health inequalities in Korea via reviewing the professionalization trend of American dental hygienists. Methods: The supervision levels of American dental hygienists, and system of dental therapists were analyzed using the data published by the relevant associations. Results: In America, dental hygienists help address oral health inequalities. However, due to limitations in the supervision levels and scope of practice of dental hygienists, the autonomy of dental hygienists was expanded, and mid-level practitioner were employed. The autonomy for dental hygiene practice was higher in public than in private in America. Some states have introduced dental therapists as mid-level practitioners. Their practice settings have limitations such as serving low-income, uninsured, and underserved patients or serving in a dental health professional shortage area. Conclusions: It is necessary to expand the autonomy of dental hygienists based on their profession. In particular, it is suggested that they start with the low-risk level practices. Further, it is necessary to introduce a dental hygiene specialist system specialized for fields with high social demands.

Among the subjects who had experience in visiting a dental clinic, 31.1% replied that they were highly interested in oral health, and to the question on the selfperceived current oral health condition, 35.1% replied that there was something wrong in their oral health condition. 2. With regard to correlation between general characteristics and interest in oral health, 79.9% of the male subjects and 83.2% of the female ones were highly interested in oral health. According to age, interest in oral health was highest among those aged 26 or older 92.0%. 3. With regard to correlation between general characteristics and oral health condition, if the presence of dental caries or periodontal disease was considered an indicator of poor oral health, 66.0% of the male subjects and 70.9% of the female ones appeared unhealthy, 72.0% of students aged 26 or older showed satisfaction. 4. The most frequent reason for not visiting a dental clinic was 'Not sick' 34.6%, and among those who had experience, the most frequent reason for visiting was 'To get treatment of sick teeth' 63.0%. With regard to the perceived kindness of dentist and dental hygienist, 40.6% and 45.8% of the subjects, respectively, were highly satisfied. The most frequent reason for satisfaction was 'Comfortable with patient reception' 34.4% and the most frequent reason for dissatisfaction was 'Explain treatment insufficiently' 30.7%. 5. As to perceived kindness according to gender, 60.9% of the male subjects and 56.1% of the female ones were satisfied with dentist's kindness, and 66.9% and 59.6%, respectively, were satisfied with dental hygienist's kindness. According to age, 62.5% of students aged 26 or older showed satisfaction with dentist's kindness and 78.3% of them with dental hygienist's kindness. 6. As to perceived kindness according to correlation between interest in oral health and current selfperceived oral condition, the kindness of dentists(68.0%) and hygienists(67.8%) was perceived higher when interest in oral health was high and not very interested and the kindness of dentists(50.0%) and hygienists(66.78%) when selfperceived oral condition was healthy, and the difference was statistically significant (p<.022 and p<.023, respectively).

Purpose: The aim of this study was to assess the degree of awareness and actual practice of dental practitioners regarding infection control during prosthodontic treatment. Materials and methods: Study participants were composed of dentists, dental hygienists, dental technicians working at dental university hospital, general hospital, dental hospital and dental clinics in Daejeon, Korea (n=126). The questionnaires included the data on general characteristics, education, awareness and practice of infection control procedures during prosthodontic treatment through personal self-administration survey. Awareness and practice were measured by Likert scale ranging from 1 to 5. Statistical analysis was done by one-way ANOVA. Influence of awareness on practice was estimated by regression analysis. Results: 27.7% of the respondents answered that the infection control education regarding prosthodontic treatment is insufficient. The mean value of awareness and practice of infection control during the prosthodontic treatment were $2.72{\pm}0.80$, $1.58{\pm}0.88$, respectively. The mean value of practice who answered that had education curriculum at college was $1.62{\pm}0.9$, and $1.31{\pm}0.49$ who did not. The mean value of awareness who equipped guideline was $3.01{\pm}0.9$, and $2.56{\pm}0.70$ who did not. Conclusion: 1. The respondents who received the infection control education by college curriculum showed higher degree of practice than the respondents who did not. 2. The respondents who have appropriate infection control guidebook in their workplace showed higher degree of awareness than the respondents who did not. 3. There was a correlation between the awareness and practice of infection control during prosthodontic treatment; the degree of awareness becomes higher, so does the degree of practice. 4. During the prosthodontic treatment, the degree of practice was lower than the degree of awareness on infection control.

Restoration of missing oral tissues by using implant therapy is one of viable options in prosthodontic treatment. The purpose of oral rehabilitation are function, esthetics and phonetics. Recently, with the increasing esthetic demand of the patient, dentists and laboratory technicians are more concern ed about natural appearance of implant prostheses. There are so many factors which affect final esthetic results of treatment such a shape, color, proportion, gingival contour etc. To provide natural and vivid looking artificial prostheses to a patient, the careful diagnosis, treatment plan and laboratory Support is crucial. Several cases will be reviewed and discussed in terms of material, gingival shape, contour, speech and connection mode etc. to fabricate natural looking implant prostheses.

Lowe syndrome, also known as oculocerebrorenal syndrome, is a rare genetic disorder involving eyes, kidney and nervous system, and occurs predominantly in mostly males. The patients with Lowe syndrome are characterized with prominent forehead, thin and sparse hair, protruding ears, congenital cataracts, glaucoma, mental retardation, stunted growth, hypotonia, decrease in muscle mass and tendon reflexes, renal tubular dysfunction, and metabolic bone disease. A 6-year-old boy with Lowe syndrome was admitted to our clinic, with multiple caries and a chief complaint of intermittent pain on the left mandibular molar area. Because of difficulty in management of behavior and his medical problem, general anesthesia was performed for dental care. No specific complication was noticed during dental treatment procedure under general anesthesia and also during periodic recall-checks. General anesthesia itself, however, could be a potentially life-threatening procedure due to patient's biomedical problems. When a dental procedure under general anesthesia is to be required in patient with Lowe syndrome, it may be advisable being teamed with physicians, and general anesthesia duration should be as short as possible.

Close communication between clinicians and dental technicians is an important factor in providing successful prostheses. The exchange of opinions with laboratories has mainly been in the form of written prescriptions and a photos, but it has been reported that information transmission may be limited. Currently, as digital technology-based prosthesis fabrication is common, 3D image objects can be stored on the web and can be easily viewed through a mobile web browser. In this article, we introduce cases where the design of the prosthesis was improved by designing the prosthesis using CAD software and reviewing the prosthesis designed with the clinical side through a web viewer. Through this protocol, it was possible to improve the occlusal surface and crown contour, the opposing teeth condition, the size of the gingival embrasure, and the shape of pontic. The process of sharing, discussing, and modifying the prosthesis design with the clinician and technician through a web viewer contributes to reflecting the diversity of oral conditions and individualized needs, thereby helping to make functional and esthetic prostheses.
