The aims of this study were to establish the effect of gender and age on number of fungiform papillae and electrogustometric thresholds of the tongue, and to determine the relation between number of fungiform papillae and electrogustometric threshold. Sixty-two healthy subjects of 20 to 39 years old were enrolled in this study. Examination areas were defined as center, anterior, left lateral, right lateral, and posterior on the dorsal surface of the tongue, which was stained with methylene blue dye and photographed with a scale bar on it. The number of fungiform papillae within $1\; cm^2$ square area of each examination site was counted twice. The counted values were averaged to produce means. Taste thresholds were measured three times on each examination area using an electrogustometer. Means of the threshold values were calculated. 1. The number of fungiform papillae was the largest at the anterior examination area, followed by right lateral, left lateral, posterior and central. Women had more fungiform papillae than men at anterior, right lateral, and center areas. Subjects in twenties showed more fungiform papillae than those in thirties at anterior, right lateral, and left lateral areas. 2. Anterior area of the tongue measured the lowest electrogustometric threshold, followed by left lateral, right lateral, posterior and center. The threshold was higher in men at anterior and right lateral areas. The subjects in thirties had higher threshold only at right lateral area than those in twenties. 3. Electrogustometric threshold was inversely correlated with the number of fungiform papillae at anterior and posterior areas. The results showed that the number of fungiform papillae and taste threshold varied according to tongue locus, and they were influenced by age and gender. The results also suggested that the number of fungiform papillae was related to electrogustometric threshold inversely.

Age estimation is fundamental and important in personal identification with forensic medicine and dentistry. Recently, a lot of studies using various part of the body have been done for age estimation. Age estimation with teeth is the most significant method comparing ones with other part of the body. Gustafson method and Johanson method using postmortem teeth have been authorized in accuracy and systemization and used domestically and internationally. The verification of the accuracy in above methods had been tried many times but it is still rare in Korea. Fifty-nine teeth(incisors, canine, premolars and molars) which were extracted due to periodontal diseases or orthodontic problem were collected. Present study is to 1) compare the accuracy of estimated age in applying Gustafson method and Johanson method to the teeth in Korea, 2) compare and analyze the correlation with results using Gustafson method and Johanson method by age, gender, maxilla - mandible and anterior - premolar - molar. Teeth were embedded in resin and sliced and then examined each one using Gustafson method and Johanson method. The results are as follows: 1. Actual age was a significant difference in estimated age by Johanson method. Actual age was a significant correlation in estimated age by Gustafson method and modified Johanson method. Modified Johanson method was more significant than Gustafson method. 2. In estimated age by Gustafson method, Johanson method and modified Johanson method, there was no significance with actual age by location and gender. 3. In estimated age by Gustafson method, Johanson method and modified Johanson method, there was significance with actual age by age group. Finally, Gustafson method and Johanson method can be used in Korea. To make more accurate verification, however, it needs more specimen and postmortem teeth. Johanson equation proposed by himself has to be developed by further studies.

By repeating nocturnal bruxism occlusal appliance's wearing condition that is used to cure temporomandibular disorders into the vitro experiment, research aims to find out how moisture infiltrated and drying cycle process affects on the surface microhardness of the resin for occlusal appliance and flexural strength. By utilizing resin for occlusal appliance which is the main component of poly methyl methacrylate, bar shaped sample was produced. For the resin sample utilized as the controlled group 1, the sample was infiltrated in the moisture for 7 days in the temperature of 37C. Then, the resin sample of the controlled group 2 was maintained in a dry condition for 7 days in the normal temperature. After that, each sample's surface microhardness and flexural strength were measured. For the resin sample that is utilized as the experimental sample, the sample was infiltrated in the moisture for 7 days in the temperature of 37C. Then, it was inundated for 8 hours a day and dried in the normal temperature for 16 hours with the continuous process of moisture infiltration and dry cycle process for 30 days. During this cycle process, sample's surface and flexural strength were measured in the 1st day, 7th day, and 30th day. Then, it was statistically analyzed to find out the difference of controlled and experiment group's surface microhardness and flexural strength. Results are 1. For the experimental and controlled group's surface microhardness of the resin for the occlusal appliance, it did not show any significant differences after moisture infiltration and dry cycle process repetition. 2. In case of the flexural strength for resin for the occlusal appliance, experimental group with moisture infiltration and dry cycle for 30 day process had greater effect than the experimental group at the 1st day and controlled group These results can be considered to be utilized from the patients of the temporomandibular disorders towards occlusal appliance used and maintained method.

Objective: The purpose of this study was to investigate the remineralization effect of bamboo salt containing dentifrice on incipient dental caries lesions using confocal laser scanning microscope by the chemical pH cycling model. Methods: Specimens of bovine tooth enamel were embedded in resin, polished, exposed to a lactate carbopol buffer system for 48 hours, and divided into 3 groups: (1)control, (2)containing SMFP(0.76% and bamboo salt 2.0% with DCPD abrasive formula), and (3)containing NaF(0.22% and bamboo salt 3.0% with a silica abrasive formula). Each group contained 12 specimens. Surface hardness was compared before and after application of the chemical pH cycling sequences for 20 days. A confocal laser scanning microscope(CLSM) was used for evaluation of remineralization on subsurfaces of enamel lesions. Results: Remineralization of bamboo salt dentifrice with NaF, silica and bamboo salt 3% was significantly greater than those for the SMFP, DCPD and bamboo salt 2% groups as indicated by surface hardness (p<0.05). Dentifrice with NaF, silica and bamboo salt 3% decreased the fluorescent lesion depth compared to the other groups by CLSM. Conclusion: Dentifrice with NaF, silica and bamboo salt 3% could be a useful preventive agent against incipient dental caries.

Dental caries and periodontal disease are the most common oral disease. Periodontal disease repidly increases during adolescence and the main cause of tooth loss in adults. This study was performed to investigate the oral health behavior and periodontal status using the community periodontal index of treatment needs(CPITN) and to find the associated factors with it of university students. The subjects were 615 students who attended to periodic health examination which was held from May 30th to June 2nd, 2000. The results were as follows; 1. The subjects were composed of 64.5% in males and 35.5% in females. The types of oral health practice were tongue brushing(61.8%). use of mouth rinsing solution(19.8), abstention of sweet foods(17.1%) in order. 2. The treatment of dental caries, scaling, tooth extraction and dental prosthesis were main causes of visit to dental clinic. 3. The scores for knowledge of oral health(male : 6.53, female : 6.70)and the number of dental caries(male : 1.96, female :2.27)were not statistically significant. 4. The degree of CPITN were 20.9% and 31.7% for 0, 3.0% and 5.5% for I, 63.7% and 55.9% for 2, 11.1% and 6.9% for 3 and 0% for 4 in males and females. 5 In males, the assorciated factors with peridonotal status were effective and frequent tooth brushing, self-congnition of oral health status, participation of oral health education and amount of dental caries. In females, efective tooth brushing, and scaling were associated with periodontal status. As a result of this study, it was concluded that more than 70 percent of subjects needed periodontal care. To keep good oral health for a lifetime. we should understand the necessity of appropriate oral health education and the early treatment of periodonal disease during adolescence.
