The purpose of this study was to make public oral health plan more effective and the improvement of the hors-pital management system for better clinical dental practice. Distribution and trends were examined in all patients who had been examined and diagnosed at Department of Pedodontics, Dental Hospital, Chosun University over 10 year-period from 1990 to 1999 Results were as follows, 1.The number of patients per year was increasing trend after 1996 and higher visiting rate in male(55.9% ) than in female(44.1%). 2.Age distribution had shown 3∼4 year-old group being the largest (23.4% ) and each percentage of 5∼6, 7∼8,0∼2. 9∼10. 11∼12, 13∼14. above∼15 year-old group was 19.9%, 17.7%, 14.6% 12.6%, 8.0%, 3.3%, 0.5%. 3.Geographic distribution showed a majority of patients in Kwang-Ju (83.0%) . Group in the suburbs of Kwang-Ju (Jang-Sung group) was 5.4%. 4.Dental caries showed the highest percentage(40.5%) in chief complaints and percentage of oral exam, orthodontic problem, oral pain, trauma. supernumerary teeth, swelling was 13.9%, 12.6% . 8.8%. 7.4% , 5.5%,4.9% 5.In all patients with traumatic problem, crown fracture showed the highest percentage(41.4%) and percentage of subluxation was 19.4%. 6 Majority(78.7% ) of patients were not refired, and percentage of patients refered from local clinic was 20.5%. 7 Patients who had periodic check-up comprised 19.6% , and percentage of after 3, 6, 9. 12, 18,24month was 36.7%,22.2%, 13.5%, 11.3%,5.4%, 11.0%.

The success of tooth transplantation or replantation depends on the viability of periodontal ligament in the transplanted tooth. Mechanical injury to periodontal tissues frequently results in dental root resorption and ankylosis, which leads to the failure of transplantation or replantation. Enamel matrix derivative (EMD) has been recently used to induce periodontal regeneration. In this report, we show a clinical case of EMD application in the transplantation of an inversely impacted and immature tooth. An impacted second premolar was found in the right maxilla of a 14 year-old girl. The tooth was inversely impacted and the root formation was incomplete. When transplantation was carried out. EMD was applied to the periodontal tissues of the extracted premolar. The tooth was fixed at the correct position and the clinical condition was followed for evaluation for 3 months. Radiographs after 3 months exhibited new bone formation surrounding the transplanted tooth. There were no signs of root resorption or ankylosis, and reconstruction of the bone defect area at the maxilla was also found. Short-term results from this case indicated that EMD application was effective in the transplantation of an inversely impacted and immature tooth. In adddition, EMD might contribute to obtain good healing without ankylosis. Further follow-up observations are necessary to evaluate the regenerative effects of EMD.

The aim of this study was to evaluate the optical density of laser fluorescence for detection of incipient caries. Prepared and polished bovine enamel specimens were demineralized in a STPP solution for varying periods of time between 3 hrs. and 60 hrs. with an area of sound enamel retained on each specimen. The randomized specimens were analyzed for optical density of enamel deminaralization using laser fluorescence. The specimens were sectioned and examined lesion depth by posarizing light microscope. Results were analyzed statistically with SAS program. The results from this study can be summarized as follows: 1. Optical density measured by laser fluorescence and lesion depth measured by polarizing light microscope was increased as demineralization time was increased(p<0.001). 2. Between optical density measured by laser fluorescence and lesion depth measured by polarizing light microscope was correlated highly(γ≥0.74956, p<0.001). 3. Regressive equation was obtained in this study as follows. Y=[X-0.260851]/ 0.000271 (R-square : 0.5618, p<0.001) (X: DENSITY, Y: DEPTH) In summary, optical density measured by laser fluorescence would be within the range of possibility to quantitatively presume demineralization amount of incipient caries lesion.

This study is finding the most appropriate model of kangwondo watershed. To synthesize earth hydrograph, It is found to several parameters which are used in existing hydrographes. then the synthestic hydrograph is compared and investigated wish many hydrographes of the rivers in kanwondo. These methods, Nakayasu, Clark, SCS are used to calculate the run-off of this watershed. When the calculated run-off is compared with real rating-curves, then it is found that the SCS method using the Clark's concentrantion time is the best way on this area having large watershed, long river length and gentle water slope, the Nakayasu method is more suitable on this area having small watershed, short river length and steep water slope. Also it is founded from analyzing run-off hydrographes, peak run-off and peak time that the Clark's method applied Kirpich's concentration time way is suitable in the area of kanwondo.

Children who have severely destructive anterior primary dentition, as in nursing bottle caries, in trauma, in rampant caries and in developmental defects. present the dentist with one of the most perplexing situations in dentistry. Especially. children with managed behaver difficultly is very severly situations. This paper reported a new technique for the utilization of resin post and strip crown to indirect methods on severely destructive primary anterior teeth. We name it "indirect short resin post crown" in this paper. Indurect technique be considered to be a simple, a retentive, retentive, intensive, color-stable and esthetic restoration.
