Pain snd disability often fractures of the cslcaneus even though the original injury was skillfully treated. The causes are traumstic arthritis of the subtalar joint, abnormalities of the peroneal tendons or weakness of Gastrocnemius, etc. We have experienced the resection of lateral prominence of calcaneus in 7 patients who complained of pain by entrapment of peroneal tendons between lateral malleolus and lateral prominence of malunited calcaneus. The follow up time after operation was 3 years and 4 months to 12 months. In all patients the pain was markedly improved between postoperative 5 weeks and 10 weeks. When the last follow up, 6 patients among 7 patients except one case of subtalar arthritis were astisfaetory.

OBJECTIVES: In 2002, the Ministry of Health and Welfare initiated a national sealant program (NSP) in public health centers in order to promote oral health among children in rural areas as well as among children with low socio-economic status in urban areas. However, this program was terminated in 2009 and substituted with the national insurance coverage of sealants (NICS). The aim of this study is to evaluate the impact of the change from NSP to NICS on regional inequality. METHODS: Based on data obtained from the 2010 and 2012 Korea National Oral Health surveys conducted, we analyzed the average number of permanent teeth with sealants (mean sealant) on the first molars and the prevalence of active dental caries in permanent teeth (D rate), segregated by region, in 8-year-old children. Analyses were performed using SPSS 21.0 (SPSS Inc., Chicago, IL, USA) after taking into consideration the complex design of the samples. RESULTS: The D rate of rural children was higher than that of those in metropolitan and city areas. Compared to the 2010 data on the mean sealants on the first molars, a 14.4% and 48.1% increase was observed in the mean sealants in children in the metropolis and in cities in 2012, respectively. However, this number decreased by 7.5% only in the rural areas. CONCLUSIONS: Accessibility to dental services was limited in the rural areas as compared than in other areas; this result is based on the fact that the D rate in rural areas was higher than that in other areas. The NSP has decreased this regional inequality with regard to the accessibility to dental services. However, it was suggested that the mean sealant on the first molars was reversed due to a change from NSP to NICS.

OBJECTIVES: This study aims to compare home care dental devices for their dental plaque removal ability. METHODS: A single blinded randomized crossover clinical study design was used to measure plaque index (Turesky Modification Quigley-Hein Plaque Index). RESULTS: All 3 groups showed a statistically significant decrease in the plaque index after usage (P<0.001). In manual tooth-brushing group, the teeth on the right dental arch showed a greater decrease in the plaque index than on the left arch (P=0.041). All appliances showed greater plaque reduction in the upper right posterior teeth than in the lower right posterior teeth (P=0.009, 0.004, 0.007). CONCLUSIONS: The results of this study support development of more effective oral hygiene appliances and emphasis on oral hygienic education.

The aim of this study was to evaluate the efficacy of a topical 0.2% hyaluronic acid (HA) preparation in the management of wound after removal of arch bar for facial bone fracture and a suture site after orthognatic, oral cancer or oral surgery. Forty patients participated in a randomized, placebo controlled, double-blind trial to evaluate the efficacy of the topical HA and preparation. HA topically applied to the wound after removal of arch bar or stitch out, 3 times a day for 4 weeks. Evaluation is performed once a week for 4 weeks. For subjective evaluation, relative pain reduction in visual analog scale (VAS) and existence of heat sensation was accessed. For objective evaluation, gross evaluation, papilla index, existence of wound dehiscence, redness and swelling was checked. The same evaluation was performed in each arch bar group and suture group. For whole subject, 0.2 % HA group resulted higher reduction than placebo group in pain of site in first week with significancy. Same findings were seen other weeks but there was no significancy. 0.2% HA group had better result than placebo in objective evaluation (papilla index, wound dehiscence, redness and swelling), but in gross evaluation placebo had better result than 0.2% HA group with no significancy. Subject was divided into suture group and arch bar group. Same aspect was seen, but only suture group had significancy not arch bar group in pain reduction score. 0.2% HA group resulted higher reduction than placebo group in pain of site in first week with significancy, especially in suture group. It reveals topical application of HA in wound especially suture site reduced pain in early stage. And 0.2% HA group had better result than placebo in papilla index, redness and swelling with no statistical significancy. In conclusion, HA has effect of pain reduction and healing promotion in the mucosal wound after oral surgery.

OBJECTIVES: The object of this study was to determine the reasons for tooth extractions of permanent teeth in Korea. METHODS: 2009 National patient samples (NPS) data were obtained for patients from the Health Insurance Review and Assessment (HIRA). We conducted a frequency analysis of the reasons for 93,176 permanent teeth extraction. RESULTS: Overall, periodontal disease was the most frequent reason for tooth extraction (54.9%), followed by dental caries (38.4%). The males lost more teeth, due to periodontal disease than the females. In the below 30 age groups, caries was the main reason for tooth extraction. However, periodontal disease was remarkably increasing in those aged that were 30 year old and over. CONCLUSIONS: Most of the permanent teeth are extracted, due to caries and periodontal disease. Furthermore, there has been no efficient way of prevention for periodontal disease in public health activities, which targeted the population of the middle age group. Such method might be required.

OBJECTIVES: The Delphi study was performed in Korea to develop a consensus opinion for the quality improvement in National oral health examination, and to obtain a basic data on how to improve the evaluation system of the National health examination. METHODS: Consensus was developed through two rounds of assessment in September and October, 2011. Seven professors and six dentists, recommended by Korean Dental Associations, were chosen as the Delphi experts. The Delphi questionnaire collected data in the following categories; management of facilities, preparation before oral screening, notice, certification of human resource, preservation of oral screening sheets, charge for oral screening, notification of agreement with using oral screening data, and the notification of oral screening results. To develop new criteria, the additional delphi questionnaire collected data in the following categories; human resource for dental screening, relevancy of instruments and facilities, a dental screening process. Respondents were asked to indicate their level of agreement with the questionnaire statements on a scale from 0 to 9 (0 indicating total disagreement and 9 indicating total agreement). The mean, coefficient of variation, median and agreement level were calculated. Agreement level was calculated by the proportion of respondents who chose more than 7. Consensus was considered to be defined when the agreement level was more than 45% in each section. RESULTS: Consensus was achieved in every criterion except for management of facilities, charge for oral screening and notification of agreement with using oral screening data. In new criteria, consensus was achieved in every criterion except for human resource for dental screening. CONCLUSIONS: Experts for the National Oral Health Examination in Korea achieved a consensus on certain aspects of the evaluation system of the National Oral Health Examination. It is needed to consider an improvement of the evaluation criteria on the National Oral Health Examination program.

Congenital cystic adenomatoid malformation of the lung (CCAM) is a rare benign pulmonary lesion characterized by abnormal overgrowth of the fetal bronchiole. The prenatal diagnosis of CCAM is important because the prognosis of the CCAM is depend on the type, bilaterality, and other associated abnormalities, which can be detected by prenatal ultrasonography. We experienced a case of CCAM that was detected by prenatal ultrasonography and report the case with a review of several related literatures.

The National Health Screening program has been implemented in Korea since 1980. First, we had searched recent scientific evidences and verified the accuracy of the data on target oral diseases. In order to determine the validity, we searched scientific bibliographic data and concluded that dental caries and periodontal disease were major oral problems. Second, we developed new improved forms for National Oral Health Screening. To improve these forms, we reviewed previous forms and gathered expert opinions. The new forms were consistent with the examination forms given to all age groups, and information on oral health conditions, dental education needs, and post-treatment care was included in the modified forms. We then designed manuals for dentists, which contained information on the screening criteria as well as consultation and patient education guidelines. The manuals were divided into three parts, including explanation of the screening criteria, standard of the decision, and education and consultation guidelines. By using these new and modified National Oral Health Screening forms, we expect an improvement in the National Oral Health Screening Program and enhancement in the oral health condition of patients.

Caries remains prevalent throughout modern society and is the main disease in the field of dentistry. Although studies of this disease have used diverse methodology, recently, X-ray microtomography has gained popularity as a non-destructive, 3-dimensional (3D) analytical technique, and has several advantages over the conventional methods. According to X-ray source, it is classified as monochromatic or polychromatic with the latter being more widely used due to the high cost of the monochromatic source despite some advantages. The determination of mineral density profiles based on changes in X-ray attenuation is the principle of this method and calibration and image processing procedures are needed for the better image and reproducible measurements. Using this tool, 3D reconstruction is also possible and it enables to visualize the internal structures of dental caries. With the advances in the computer technology, more diverse applications are being studied, such automated caries assessment algorithms.
