Purpose: The dental age estimation of children is performed using dental maturity. Postmortem missing of the anterior teeth or the distortion of image of the anterior teeth in panoramic radiographs can make it difficult to analyze the development of the anterior teeth. This pilot study was conducted to derive a new age estimation method based only on the developmental stage of mandibular posterior teeth. Methods: This study was conducted using panoramic radiographs of 650 subjects aged 3 to 15 years old. The dental developmental stages of the lower left first premolar, second premolar, first molar and second molar were evaluated according to the Demirjian's criteria. The intra-/inter-observer reliability was evaluated, and multiple linear regression analyses were performed including the developmental stage of each tooth as an independent variable. Results: The intra-/inter-observer reliability was 0.9626 and 0.8877, respectively, and showed very high reproducibility. Multiple linear regression analyses were performed for males and females, and the age calculation table was derived by obtaining the intercept and the coefficient according to the development stage of each tooth. The coefficient of determination (r²) of the age calculation method was 0.9634 for male and 0.9570 for female subjects, and the mean difference between chronological age and estimated dental age was -0.42 and -0.21, respectively. Conclusions: This pilot study evaluated the developmental stages of four lower posterior teeth in the Korean group according to Demirjian's criteria, and derived age estimation method. The accuracy was lower than when more teeth were used, but it will be useful to estimate age of children when the anterior teeth are difficult to accurately analyze.

The number of geriatric patients seeking dental service is ever-rising because of increased life expectancy, also with problem of increased chronic medical conditions. One of them are patients on anti-thrombotic medication. Bleeding complication after minor oral surgery by anti-thrombotic agents is of concerns to dentists on dental management of these patients. Risk and benefit of the anti-thrombotic agents must be weighed before initiating dental procedures, which should be established as a treatment guideline. Purpose of the paper is to optimize the management of the dental patients on antithrombotic medication via standardization of treatment protocol of such a patient.

Objectives : This study aims to provide the basic data for the maintenance and management of healthy implants through finding out the educational experience of toothbrushing and the oral hygiene management for the implant patients and to determine the maintenance measure. Methods : From April 1 to october 1, 2012, 250 patients in the dental clinic in Daejeon completed the self-reported questionnaire. Results : As for the educational experience of toothbrushing, 66.4 percent received the training for toothbrushing and 33.6 percent had not received the training for toothbrushing. Those who brushed three times a day accounted for 74.1 percent. Those who received the training for toothbrushing comprised 56.0 percent and took regular check up of every 6 months. Approximately 50.0% received regular scaling service every 6 months. Periodical medical check up comprised 55.6% among those who received toothbrushing education. Approximately 63.9% thought that periodical medical check up is the most important to maintain oral health. Conclusions : There were important factors for oral health. They were tooth-brushing, the utilization of various oral hygienic products, and the awareness of importance of oral hygiene management. The customized education program for the general public should be implemented as regular as possible.

Objectives: The purpose of this study is to look into the health insurance systems and application in Korea and Japan in order to improve elderly people's quality of life. Their quality of life can be improved by upgrading the long term care systems; and extending treatment and prevention. Methods: This study is to examine long term care systems articles through content analysis in the National Health Insurance Service. Data were collected from the printed Internet and analyzed. Results: A part-time dentist system in elderly care facilities has trouble in taking care of old people's oral health due to both lack of time and operational difficulties. It is urgent to arrange dental experts who can permanently stay in care facilities and to build systems which can be managed periodically and continually. Conclusions: As having staff training for the efficiency and using the manpower in care facilities (care workers), it is necessary to solve the unequal medical service in oral health care for the elderly in Korea.

Purpose: This study aimed to evaluate the structural complexity of craniofacial trabecular bone in multiple myeloma by fractal analysis of panoramic and lateral skull radiography, and to compare the fractal dimension values of healthy patients (HPs), pre-treatment patients (PTPs), and patients during bisphosphonate treatment (DTPs). Materials and Methods: Pairs of digital panoramic and lateral skull radiographs of 84 PTPs and 72 DTPs were selected. After application of exclusion criteria, 43 panoramic and 84 lateral skull radiographs of PTPs, 56 panoramic and 72 lateral skull radiographs of DTPs, and 99 panoramic radiographs of age- and sex-matched HPs were selected. The fractal dimension values from panoramic radiographs were compared among HPs, PTPs, and DTPs and between anatomical locations within patient groups using analysis of variance with the Tukey test. Fractal dimension values from lateral skull radiographs were compared between PTPs and DTPs using the Student t-test. Pearson correlation coefficients were used to assess the relationship between the mandible from panoramic radiographs and the skull from lateral skull radiographs. Intra-examiner agreement was assessed using intraclass correlation coefficients (α=0.05). Results: The fractal dimension values were not significantly different among HPs, PTPs, and DTPs on panoramic radiographs or between PTPs and DTPs on lateral skull radiographs (P>0.05). The mandibular body presented the highest fractal dimension values (P≤0.05). The fractal dimension values of the mandible and skull in PTPs and DTPs were not correlated. Conclusion: Fractal analysis was not sensitive for distinguishing craniofacial trabecular bone complexity in multiple myeloma patients using panoramic and lateral skull radiography.

The purpose of this study is to analyze the cost of dental implant by top-down method and, on that basis, to provide salient information for the suitable standard of dental insurance fee. A survey data and accounting documents from 36 samples of dental clinics secured with the organisation authority are used and analysed for extracting the representative sample of dental clinic. A researcher visited the dental clinics in person and conducted additional interviews in the omitted case of accounting documents. A dental implant cost by top-down method was estimated to 1,430,000 won. Labor cost accounted for 43% of the total cost structure, ranking it 1st and, management cost, material cost and interest cost on investment cost in order are investigated. Labor cost counts of the total cost that shows the similar aspect to the existing result. Cost in cost accounting of medical care would be used for the judge that cost pursed value for dental service, not price or fee.

Purpose: This study aimed to obtain basic data on oral health improvement by investigating the EQ-5D index according to the oral prosthesis status of elderly persons aged 65 years or older in Korea using the Seventh Korea National Health and Nutrition Examination Survey. Methods: In this study, 3,426 elderly persons aged 65 years or older were included to analyze the relationship between the dental prostheses status and EQ-5D index in the collected data. Results: Compared to the "complete denture" in oral prosthesis, EQ in case of no dental prostheses or fixed dental prostheses is comparable to removable prosthetics such as "no dental prostheses," "one fixed bridge," and "two or more fixed bridges." Removable partial denture and complete denture required for the maxillary and mandibular EQ-5D index were significantly higher in "not necessary" than in "complete denture necessary" in all the elderly persons. Conclusion: The condition of the dental prosthesis and the need for a removable partial denture and complete denture for the elderly's EQ-5D index were confirmed, and it was found that the fixed dental prostheses were more effective than the removable dental prostheses. Therefore, oral health education programs for the elderly should be developed to promote dental function and oral health maintenance.
