This study was conducted to evaluated dental health promotion behavior and dental health belief of dental hygiene students in Gwangju and Chunnam. The results of this study were as follow: (1) Higher perceived susceptibility was more decreased grade(p<0.001) and more decreased economic level(p<0.05), more perceived dental healthy(p<0.001). Higher perceived benefit was more increased grade(p<0.001), at perceived health was very unhealth(p<0.05), at perceived dental health was very unhealth(p<0.05), in case of dental office visit before 1 year was highier(p<0.01). Higher perceived seriousiness was at middle economic level(0.01), more increased perceived unhealth status(p<0.05) and perceived unhealthy dental status(p<0.01). Higher perceived salience was more increased grade(p<0.001), in case of dental office visit before 1 year was highier(p<0.001). Higher perceived barrier was more increased grade(p<0.001), more increased economic level(p<0.05), at perceived health was very unhealth(p<0.01). (2) Higher dental health promotion behavior was more increase grade in preventive dental utilization and user dental health recomended device and selection eating case of healthful food to dental health and selection uneating case of harmful food to dental health(p<0.05). (3) performance in dental health promotion behavior was significantly correlated with perceived susceptibility(r=-0.081), perceived benefit (r=0.133), perceived seriousiness(r=0.210), perceived salience(r=0.187).

Actinomycosis is an infrequent chronic infection regarded as the most misdiagnosed disease by experienced clinicians. The Office of Rare Diseases at the National Institute of Health has also listed this disease as a "rare disease." This article presents a case report of actinomycosis of the alveolus with unusual clinical features but a successful resolution. It also states the importance of biopsy of deceptive inflammatory lesions that do not respond or recur after conventional treatment modalities.

Objectives: Although a few studies have investigated the relationship between kidney and oral function (number of remaining teeth), their results remain inconclusive. Therefore, this study aimed to investigate the relationship between kidney function and oral health in community-dwelling healthy elderlies and examine the factors associated with kidney function. Materials and Methods: We used cross-sectional data from the Shimane prefecture cohort recruited by the Center for Community-Based Health Research and Education in 2019. We collected clinical data on dental status, background factors and kidney function (estimated glomerular filtration rate [eGFR], mL/min/1.73 m² and creatinine levels, mg/dL). Results: The study enrolled 481 participants, whose mean age was 66.7±7.4 years, and 223 (46.4%) participants were men. Multivariate analysis revealed significant correlations between eGFR (B=0.17, P=0.04), creatinine (B=-0.54, P<0.01), and the number of remaining teeth. The number of remaining teeth was associated with creatinine and eGFR, which are indicators of kidney function. Conclusion: This study suggests that preserving the teeth may prevent decline in kidney function. Dental professionals should provide instructions and professional care to reduce the risk of systemic diseases such as kidney dysfunction.

3D printing is a process of producing 3d object from a digital file in STL format by joining, bonding, sintering or polymerizing small volume elements by layer. The various type of 3d printing is classified according to the additive manufacturing strategies. Among the types of 3D printer, SLA(StereoLithography Apparatus) and DLP(Digital Light Processing) 3D printer which use polymerization by light source are widely used in dental office. In the previous study, a full-arch scale 3d printed model is less precise than a conventional stone model. However, in scale of quadrant arch, a 3d printed model is significantly precise than a five-axis milled model. Using $3^{rd}$ Party dental CAD program, full denture, provisional crowns and diagnostic wax-up model are fabricated by 3d printer in dental office. In Orthodontics, based on virtual setup model, indirect bracket bonding tray can be generated by 3d printer. And thermoforming clear aligner can be fabricated on the 3d printed model. 3D printed individual drilling guide enable the clinician to place the dental implant on the proper position. The development of layer additive technology enhance the quality of 3d printing object and shorten the operating time of 3D printing. In the near future, traditional dental laboratory process such as casting, denture curing will be replaced by digital 3D printing.

Purpose : The current research examines the muscle activity that happens during scaling practice subject to 20 dental hygienic students with musculoskeletal pain and then propose a basic data according to the working attitude of the Dental Hygienist. Method : The Nordic-style questionnaire is used to define experimental group with musculoskeletal pain and control group. During the scaling the surface EMG device is used to measure the muscle activity of experimental and control group. Study design : The surface EMG is measure RMS(root mean square) of suboccipital muscle, biceps brachii, upper trapezius, and brachioradialis muscle activity. Results : In the experimental group, the RMS of upper trapezius and brachioradialis is increased during scaling practice(p<0.05), but the control group's RMS is not changed(p>0.05). Conclusion : Musculoskeletal pain may contribute to increase muscle activity of neck & arm during scaling practice. In the future we think there is a need to raise the office efficiency by subjecting to dental hyginiest that are in the clinics and performing experiments.

It has been suggested in research results thai dental hygienists have high risk of carpal tunnel syndrome, mainly caused by the repeated motion of extensor and flexor or the use of vibration tools, compared to other occupations. To find out the situation of the carpal tunnel syndrome of dental hygienists, who are exposed to work-related musculoskeletal disorders, this study used 132 questionnaires given on May 22, 2004, the period of continuing education of the first half year in the Gwangju Jeonnam area, and obtained the following results. 1. Subjects worked at a dental ciinic(32.6%), a hospital(31.8%), and a public health center(35.6%). Age by work was under 24 in a clinic(17.4%) and a hospital(15.9%), and over 30 in a public health center(35.6%). 2. In practice conducted over one time a day, a scaling accounted for 90.7% in a doctor's office; 595% in a hospital; and 3.0% in a public health center, suggesting significant difference(p<0.01). Pit and fissure sealant accounted for 53.5% in a clinic; 53.2% in a hospital; and 95% in a public health center, also suggesting significant difference(p0.01). 3. Symptoms of carpal tunnel syndrome appeared in a wrist(12.1%), a right hand(14.4%), and a left hand(5.3%). 4. In case of temporary crown practice, symptoms appeared in a wrist(22.0%), a right hand(14.0%), and a left hand(4.0%), suggesting significant difference(p<0.01). The above results showed that 12.1% of dental hygienists was exposed to carpal tunnel syndrome. Thus, it is considered very important that dental hygienists should be given education of the danger of continuous work in certain motions and prevention education of improving repeated position, and make efforts to reinforce self-control ability.

Background: The management of the behavior of handicapped children when providing required dental care is often a problem, whether in the dental office or in a hospital setting. Because of the high incidence of poor cooperation, many of these patients are scheduled for dental care under general anesthesia with preoperative medical assessment. The purpose of this study was to carry out a clinico-statistical survey on dental treatment for handicapped children under general anesthesia. Methods: After approval from the institutional review board, the medical records of 64 handicapped children between 1997 and 2002 were reviewed to determine the patient profiles, anesthesia management, and complications. The charts of these patients, who underwent dental examination, scaling and prophylaxis, and restoration and extraction of teeth under general anesthesia, were reviewed. Results: The mean age was 12.8 years old, and males (53%) predominated females (47%). Twenty-four patients had mental retardation, twelve had autism, six had cerebral palsy, 4 had behavior disorder, others had heart disease, convulsive disorder, etc. Sixty-two had intravenous thiopental with neuromuscular blocker, 2 had intravenous ketamine induction. Nasotracheal intubation was uneventful in 55 patients, nine had orotracheal intubation because of difficult visualization of the larynx. Twenty-one patients experienced postoperative complications in the recovery room, including epistaxis, nasal obstruction, vomiting, airway obstruction, respiratory depression. Conclusions: General anesthesia is a very effective way of completing the dental treatments for disabled children. We emphasize the need to train anesthesiologists in the care of disabled patients.

The purposes of this study were to investigate the oral health status of the disabled children attending special schools in Seoul and Gyeonggi area, which were to collect baseline data for set up a oral health center in special schools. The study group comprised 915 disabled children aged 12~15 year. They were examined clinically and surveyed on 4 oral health related characteristics according to the type and level of disabilities The results may be summarized as follows: 1. DMFT index was the highest in children with crippled disorder. The plaque control was more required to the children with mental retardation or developmental disorder other than another types of disabilities. 2. About one third of the children with mental retardation or developmental disorder had their teeth brushed at least 3 times daily without any help. Over the half of the children with crippled disorder had their teeth brushed 2 times daily, 33.3% were independent and 38.9% totally dependent on help from others. 3. The more level of disabilities was higher, the more frequency of tooth brushing was lower and degree of dependance of the tooth brushing was higher. 4. There was tendency to visit to dental office more frequently for relief of dental symptoms in children with crippled disorder 5. The inability to call for help from others was the major barrier to dental care for the disabled.
