OBJECTIVEThe purpose of this investigation is to find out a method to evaluate dental manpower resources.

METHODSWe selected population, GDP, number of dentist and number of different oral health professionals from certain internet stations, published books and journals from 1996 to 2000 as our investigating data.

RESULTSData was collected from 100 countries. Our investigation found that the design of dental manpower index to evaluate dental manpower resources was effective and convenient.

CONCLUSIONDental manpower index is a good method to evaluate dental manpower resources.

PURPOSE: The aim of this study was to assess the esthetic outcome of maxillary anterior single implants by comparing the esthetic perception of dental professionals and patients. MATERIALS AND METHODS: Twenty-three patients with single implants in the esthetic zone were enrolled in this study. Dentists of four different dental specialties (Three orthodontists, three oral surgeons, three prosthodontists, and three periodontists) evaluated the pink esthetic score (PES)/white esthetic score (WES) for 23 implant-supported single restorations. The satisfactions of the patients on the esthetic outcome of the treatment have been evaluated according to the visual analog scale (VAS). RESULTS: The mean total PES/WES was 12.26 ± 4.76. The mean PES was 6.45 ± 2.78 and mean WES was 5.80 ± 2.82. There was a statistically significant difference among the different specialties for WES (P<.01) and Total PES/WES (P<.01). Prosthodontists were found to have assigned poorer ratings among the other specialties, while oral surgeons gave the higher ratings than periodontists, orthodontists, and prosthodontists. CONCLUSION: Prosthodontists seemed to be stricter when assessing aesthetic outcome among other specialties. Moreover, a clear correlation existed between dentists' and patients' esthetic perception, thereby providing rationales for involving patients in the treatment plan to achieve higher levels of patient satisfaction.

Osteonecrosis of the jaw (ONJ) is a well-known pathological condition in oncology derived from the use of bisphosphonates (BPs) and denosumab. Many molecular and immunological targets have been introduced for daily use in cancer treatment in recent years; consequently, new cases of ONJ have been reported in association with these drugs, especially if administered with BPs and denosumab. When the drugs are administered alone, ONJ is rarely seen. The objective of our study was to analyze the recent literature relative to the association of ONJ with these new drugs highlighting the pathogenic, clinical and therapeutic aspects. The close collaboration between maxillofacial surgeon, oncologist, dentist, and dental hygienist remains the most important aspect for the prevention, prompt recognition, and treatment of this pathology.

Aircraft accidents are not new occurrences. Most people considered flying to be particularly dangerous in the early days of flight, and fatal aircraft crashes were not surprising Although investigation into the mechanical causes of crashes progressed, it was not until the 1950s that value of medical investigation of aircraft crashes became apparent. The identification process is an essential elements of an adequate investigation. Accurate identification of all fatalities incurred in an aircraft accident is often the first step in determining where each person was located at the time of the disaster and what role they may have played in its cause, Separated into basic elements, the identification process involves (1) the collection of identification information about missing persons, (2) the observation of identifying features of the victims, and (3) the comparison of the two groups of information. Many investigators know about identification techniques, but they have considered them as an isolated process anti have not integrated them into the overall investigation. Typically, physicians, dentists, and other medical personnel are assigned tasks based on a preconceived disaster plan that they had no role in developing to identify the victims of aircraft crash occurred in Guam at 6 August 1997, we performed analysis the data filed from the National Transportation Safety Board (NTSB), Office of Chief Medical Examiner, Territory of Guam, U.S.A. and National Institute of Scientific Investigation, Korea (NISI). The total of passengers on boards were 254 including 23 all-crews, Among them, only 25 (22 passengers and 3 air crews) were survived. We obtained that the first identified bodies were 100 remains including hospital dead 7 cases using by conventional methods such as finger prints, medical & dental records, and so on. We also analyzed he victims' seating configuration based on boarding pass and surveyed the process from the identification & notification to releasing the body, funeral services and transportation.

OBJECTIVES: This study investigated the busyness of dentists and analyzed factors related to busyness in these professionals. METHODS: The subjects were 243 practicing dentists. Surveys were carried out via mail. Busyness was measured by using the Mumma scale. The data were analyzed using the Kruskal-Wallis test. RESULTS: The dentists' busyness index was 1.91. Of the participants, 40% of practicing dentists wanted more patients, 30.8% did not overwork but did not want more patients, and 27.1% overworked and did not want more patients. The busyness index was significantly related to the number of dental hygienists and dentists. However, it did not differ with respect to the number of assistant nurses. CONCLUSIONS: The busyness index should be considered when developing relevant human resource plans.

OBJECTIVES: This study was conducted to investigate the awareness of the students currently attending dental colleges/schools in Seoul regarding the scope of work done by a dental hygienist (DH) and a chair-side dental assistant (DA).METHODS: A direct questionnaire survey was conducted among 950 students who currently attend dental colleges/schools in Seoul. We were able to use a total of 458 samples for final analysis after excluding inappropriate ones. The contents of this structuralized survey included the obligation of proper name badge use for dental health care personnel, the legal work scopes of a DH and a DA in accordance with the revised execution of the ‘Legal Acts on Medical Technicians’, and the inclusion/exclusion of such contents from dental colleges/schools curricula. The results were statistically analyzed via the IBM SPSS Statistics 25.0 software.RESULTS: Many subjects were aware of the difference in scope of work performed by a DH and a DA (P < 0.001), but not their legal obligation to wear appropriate name badges in accordance with the ‘Proposal for the Establishment of the Name Badge Standards for Healthcare Practitioners'. The subjects generally showed higher comprehension of the scope of work performed by a DH (74.3%) than that performed by a DA (57.7%). Without the presence of any corresponding curriculum, accurate responses tended to increase with the students' seniority. Most students (94.4%) agreed with the need to include a class that teaches the scope of work performed by a DH and a DA in their school curricula.CONCLUSIONS: We have found that education regarding ‘Name Badge Standards for Healthcare Practitioners’ and classification of a dental assistant's scope of work is lacking in the existing curriculum. Therefore, it is necessary to establish additional curriculum.

Dental practice can produce and spread some infetious diseases from patients to dentist, dental assistant, and dental labors. One possible method for preventing these cross-contamination is to immerse dental impression in chemical disinfectants. So far many investigators studied on the dimensional changes of dental impressions and on the surface qualities of stone casts made from impression following immersion in disinfectants. This study was proposed to evaluate some popular impression/disinfectant combination from the point of dimensional stability. Impression was taken from dental arch-shaped metal model. Irreversible hydrocolloid and 3 elastomers(polyvinyl siloxane, polysulfide, polyether) were immersed in 3 disinfectants (2% glutaraldehyde, 1% povidone-iodine, 0.5% sodium hypochlorite) for 10 minutes and measured both cross-arch and anterior-posterior distance under stereo microscope to evaluate dimensional change. The results obtained were as follows: 1. Dimensional changes of irreversible hydrocolloid impression was statistically different in crossarch and anterior-posterior distance when immersed in 2% glutaraldehyde solution and in anterior-posterior distance when immersed in 0.5% sodium hypochlorite solution from control group(p<0.05). 2. Dimensional changes of polyvinyl siloxane and polysulfide impression were not statistically different from control group (p>0.05). 3. Dimensional changes of polyether impression was statistically different in cross-arch distance when immersed in 0.5% sodium hypochlorite solution and in anterior-posterior distance when immersed in 1% povidone-iodine solution from control group (p<0.05). 4. In all cases, dimensional changes were less than 0.1% from the original dimension and concluded clinically acceptable

Dentists

This study's aim was to investigate their opinions to improve the educational system for dental hygienists on the basis of their duties as dental hygienists. The qualitative study was conducted among 19 dental hygienists at Daejeon, Korea from July to August 2016. Two researchers followed each subject for working hours in a day and recorded all the tasks and time to take for each task. After one day, the researchers met each subject and conducted face-to-face interviews to investigate the opinions about the dental hygiene curriculum and national board examination. The main duties recognized by more than half of the subjects were oral disease prevention including scaling and dental treatment assistance. The subjects' minority opinion about the main duties included radiography, impression taking, dental implant surgery assistance, orthodontic treatment, patient counseling, dental management and staff management, and oral health education. The most important tasks perceived by the subjects were prosthetic and implant impressions, scaling and implant surgery assistance. The subjects' minority opinion about the most important duties included patient counseling and making temporary crowns. The most difficult tasks answered by the subjects were prosthetic and implant impressions and dental implant surgery assistance. The subjects' minority opinion about it included patient counseling, scaling, and making temporary crowns. They mentioned that their curriculum in college was different from the actual work and the national board examination was not reflective of their real duties. We found out Korean dental hygienists had a lot of roles as dental assistants, dental business managers, and so on. We suggest that the law, curriculum and national board examination for dental hygienists should be revised to be able to reflect the reality of the clinical field.
