Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

This study was conducted to evaluate the temperature rise on the root surface while the root canal is being obturated using continuous wave of condensation technique. Maxillary central incisor was prepared for repeated canal obturation. Ten thermocouples (Omega Engineering Inc., Stanford, USA) were placed at 1mm increment from the anatomical root apex. The real temperature of Buchanan plugger was recorded before insertion into the root canal. The root canal was obturated with continuous wave of condensation technique as described by Buchanan and the root surface temperature was recorded during obturation at 150℃, 200℃, 250℃ and 300℃ temperature settings of System B HeatSource (Model 1005, Analytic technologies, Redmond, WA, USA). After completion of the temperature recording, the dentinal-cementum thickness at each sites was measured. The data were analyzed using one-way ANOVA followed by Scheffe's test and linear regression test. The results were as follows. 1. When the temperature was set at 150℃, 200℃, 250℃ and 300℃ on the digital display of System B HeatSource, the real temperature of the plugger at the 1mm point from the tip revealed 130.82±2.96℃ 158.00±5.26℃, 215.93±6.91℃ and 249.88±3.65℃ respectively. 2. The position of 8 mm from the anatomical apex showed the highest temperature increase at each temperature settings and it was significantly higher than those of other positions (p<0.01). The temperature rise was constantly increased toward coronal portion from apex of the root. 3. The maximum temperature increase on the root surface was 2.37±0.09℃ at 150℃ setting, 3.11±0.12℃ at 200℃ setting, 3.93±0.09℃ at 250℃ setting and 5.69±0.15℃ at 300℃ setting respectively. These results suggest that it be relatively kind to the supporting tissues of the root that the root canal is obturated using continuous wave of condensation technique at 150℃, 200℃, 250℃ and 300℃ temperature settings on digital temperature display of System B HeatSource.

This study was conducted to evaluate safety to the supporting tissues of the root while the root canal is obturated using continuous wave of condensation technique. A extracted maxillary central incisor was prepared for repeated canal obturation. After conventional access opening, working length was then established to the point 1㎜ from anatomical root apex. The root canal was prepared with GT rotary Ni-Ti file (Dentsply Maillefer, Switzerland). Five thermocouples (Onega Engineering Inc., USA) were placed at 2㎜ increments on one side beginning 1㎜ from the anatomical root apex and the other five thermocouples at 2㎜ increments on the other side beginning 2㎜ from it. For obturation, a nonstandardized medium size gutta-percha cone and a ML Buchanan plugger (Analytic technologies, USA) were selected. After drying of root canal, AH 26 root canal sealer (Dentsply Detrey, Germany) was applied on the wall of the root canal. Baseline temperature was measured on the root surface. The ML size plugger was preheated for 2seconds and then the real temperature of it was recorded before insertion into the root canal. The root canal was obturated with continuous wave of condensation technique as described by Buchanan. The root surface temperature was recorded during obturation and it was performed ten times at each of the following temperature settings: 150℃, 200℃, 250℃ and 300℃. After completion of the temperature recording, the dentinal-cementum thickness at each sites where thermocouples were attached was measured. The data were analyzed using one-way ANOVA followed by Scheffe's test and linear regression test. The results were as follows. 1. When the temperature was set at 150℃, 200℃, 250℃ and 300℃ on the digital display of System B HeatSource, the real temperature of the plugger at the 1㎜ point from the tip revealed 130.82±2.96℃, 158.00±5.26℃, 215.92±6.91℃ and 249.88±3.65℃ respectively. 2. The position of 8 ㎜ from the anatomical apex showed the highest temperature increase at each temperature settings and it was significantly higher than those of other positions (p<0.01). The temperature rise was constantly increased toward coronal portion from apex of the root. 3. The maximum temperature increase on the root surface was 2.37±0.09℃ at 150℃ setting, 3.11±0.12℃ at 200℃ setting, 3.93± 0.09℃ at 250℃ setting and 5.69± 0.15℃ at 300℃ setting. These results suggest that it be relatively kind to the supporting tissues of the root that the root canal is obturated using continuous wave of condensation technique at 150℃, 200℃, 250℃ and 300℃ temperature settings on digital display of System B HeatSource.

Objectives : By analyzing the affects of the mother`s oral care to the caries experiences of the elementary school children, To looking for the way to prevent dental caries in the primary school, to provide baseline data to perform the associated oral health education. Methods : Between the 3,676 children`s dental check-up data and the 2,934 survey of parents from 9 elementary schools in the the Gyeonggi Province, the exactly matching data of 2,358 pairs, children versus mothers, were analyzed during the period, 2009 May 4 to July 20, By using the PASW 18(SPSS-PC 18), Frequency analysis of the collected data, and cross-analysis, ANOVA, Bonferroni post-analysis was performed. Results : The findings of the study were as follows. 1. In children, the ratio(DMF rate)of the dental caries experience in permanent teeth, appeared higher for men than women. Divided by grade level, the ratio of caries experience in the permanent teeth(DMF rate) generally appear higher in older than young. Thus between the child`s gender and grade level by the ratio of caries experience in the permanent teeth(DMF rate) showed the statistically significant differences (p<0.05). 2. Between the socioeconomic characteristics of mothers and the children`s level of dental caries experiences, not showed the statistically significant difference.(p>0.05). 3. The significant difference showed between the dental caries levels of the children and the mother`s oral health care behavior - a toothbrush replacement period, mother`s broken teeth, mothers guidances of the brushing after snacks for children(p<0.05). Conclusions : The mother`s oral health attitudes and behaviors can affect to their children`s oral care habits. Therefore The mother themselves should have the right proper habit of oral health care, so that in oral health care mothers should be the model for their children. Institutionally more systematic and detailed oral health educational program in conjunction with the family is needed.(J Korean Soc Dent Hygiene 2012;12(1):145-156)

조진숙,황윤찬,김선호,황인남,최보영,정영진,정우남,오원만 전남대학교 치의학연구소 2003 구강과학 Vol.15 No.4

This study was performed to confirm the actual temperature rise on the surface of Buchanan plugger by evaluating the temperature rise on the surface of it, the peak temperature of pluggers of various size using thermocouple. The heat carrier system 'System B Heatsource' (Model 1005, Analytic Technologies, USA) and the Buchanan pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200 which Dr. Buchanan's "Continuous wave of condensation" technique recommended on digital display and the power level on it was set to 10. The touch mode was used. Five thermocouples were placed in direct contact with the surface of each size of Buchanan's pluggers at 1 ㎜ increments from the tip to the 4 ㎜ length of shank. Each thermocouple was secured with cyanoacrylate adhesive and orthodontic resin block. The two wire leads of each thermocouple were connected to the appropriate channels of Data Logger. This was configured to simultaneously record input from the five thermocouples. The heat control spring was touched for 1, 2, 3, 4 and 5 seconds, and the temperature rise on the surface of the pluggers were measured at 1 sec intervals for more than 5 seconds with an accuracy of 0.01. Ten trials was determined for each plugger. The average of temperature rise and standard deviation was calculated for each size of plugger. The data were statistically analyzed by one-way ANOVA to determine their significance. The results as follows. 1. The position at which the temperature peaked was approximately at 1∼2㎜ far from the tip of Buchanan plugger (p<0.01). 2. The peak temperature was 215.25±2.28℃ in F plugger, 185.94±2.19℃ in FM plugger, 169.51±9.12℃ in M plugger, and 160.79±1.27℃ in ML plugger and the peak temperature was highest in F type and followed by, in descending order, FM type, M type. ML type showed the lowest peak temperature (p<0.01). This results suggest that the actual temperature on the surface of the pluggers does not correlate well with the temperature set on digital display. Heat concentrates around the tip. The larger plugger reveals lower temperature rise relatively.

As sensitive images what users recently feel on the design of web sites affect user's satisfaction and the frequency of revisit, it's necessary to grasp the sensitivity preference based on the characteristics of web sites, and specially it is demanded to analyze the sensibility of user's characteristics as customized web sites has been emphasized. There are relatively abundant guide lines on designing taking a side view of aesthetics though most of guide lines are based on designer's intuition and common sense. This study focuses on design methodology what can bring about the sensibility from users which coincides with the purpose of the web sites, breaking from the design which was focused on efficient usability . First of all, web sites which have well awareness are selected and categorized into 4-5 categories and the color schemes are assorted from the categories. The color schemes are constructed in the image scale space of I.R.I Color Laboratory and the sensitive adjectives are extracted. Through the research, it is recognizable that user's sensitivity was almost the same as the extracted sensitive adjectives which can show a well-planned color scheme can make a planner's intended sensitivity to accord with a user's sensitivity. Effective color scheme can build up and enhance the sensitive communication between planners and users. This study will be a significant chance to suggest that efficient color schemes can be constructed based on the sensitive adjectives and the color schemes and designers can objectify characteristics of their subjective sensitivity and make an opportunity to build up the sensitive communication and to enhance the sensitive communication on web sites.

가족성 저인산혈증(famiial hypophosphatemia)은 근위 세뇨관의 인산 재흡수 기전의 결핍으로 혈청 칼슘 농도는 정상이나 혈청 인산 농도가 낮아져 저인산혈증을 나타내는 가장 흔한 유전성 구루병이다. 혈청 인산이 낮음에도 불구하고, 소변으로의 인산 배출이 증가되어 있고 혈청 알칼리성 인산 분해 효소의 상승이 현저하다. 주로 반성 우성 유전이며 보통 남아에서 여아보다 임상 증상이 심하다. 이러한 가족성 저인산혈증 환자의 전신적 소견으로는 앞이마의 돌출, 사각형 머리, 작은 키, 휜 다리가 나타나며, 치과적 소견으로 치조백선과 치낭의 비박, 얇은 법랑질, 확장된 치수강과 근관, 치근단 농양과 치주 농양의 높은 발생률, 원인불명의 치근단 희박화 골염이 나타난다. 본 증례는 유치 충치 치료를 위해 내원한 환아가 임상적으로 작은 키와 휜 다리, 방사선적으로 많이 확장된 치수강과 근관이 관찰되어 소아과에 의뢰한 바 가족성 저인산혈증으로 진단받아 그 임상적 소견과 치과적 치료에 대해 보고하는 바이다. Familial hypophosphatemia is the most common hereditary rickets which occur hypophosphatemia as the calcium concentration in the blood serum is normal but the phosphate concentration in the blood serum decreases by dysfunction of renaltubular phosphorus reabsorption. In spite of the low concentration of phosphate in the blood serum discharge of phosphate by urine and alkaline phosphatase increases remarkably. It is a sex-linked and normally male show severe clinical symptoms than female. This kind of familial hypophosphatemia patients show frontal bossing. square head, short of status for general finding, and for dental finding, thinning of limina dura and dental follicle, thin and hypoplastic enamel, enlarged pulp chamber and canal, high occurance rate of periapical and periodontal abscess and unknown cause of rarefying osteitis. This case is to report about the clinical finging and dental treatment of a child patient, who came to the hospital for treatment of deciduous teeth caries but was refered to pediatrics because the child showed clinically short of status, bow-leg and radiographically enlarged pulp chamber and canal, there as diagnosed as familial hypophosphatemia.
