Herpes simplex is caused by viruses of the herpesvirus hominus family. HSV have four categories: type 1, 2, 6, and 8. Generally HSV-1 affects the mouth. Once infected by HSV, the person's infection is permanent. Retrograde transport through adjacent neural tissue to sensory ganglia leads to a lifelong latent infection. Recently, we treated a patient with recurrent herpes-stomatitis mimicking acute necrotizing ulcerative gingivitis (ANUG). The results were satisfactorty so we report this case. 31 years old male patient showed sore throat, gingival ulceration, palpable both submandibular lymph node, and sulcular pus formation around posterior decayed teeth. This is the third time he has suffered from this symptom. Tentative diagnosis was acute necrotizing ulcerative gingivitis. Antibiotic therapy was started. But, intraoral symptom got worse in process of time. Especially ulcer of marginal gingiva got worse. Viral disease was suspected. We carried out viral cultivation. At the same time topical application of antiviral ointment (herpecid$^{(R)}$) was performed on oral ulcer unilaterally for the purpose of diagnosis and reducing pain experimentally. The next day pain was decreased dramatically on application area. Basing on the viral cultivation and clinical effect of antiviral ointment (herpecid$^{(R)}$), we have diagnosed it as a recurrent herpes-stomatitis and concluded that viral infection was major cause of disease and bacterial infection was secondary.

Purpose: The objective of this study was to evaluate the caries prevention effect of school-based fluoride mouth rinsing (FMR) program implemented in the Hanuul district of Mongolia, which has a very low socioeconomic status and extremely poor infrastructure for oral health. Materials and Methods: One hundred and seventy children aged from 6 to 8 years of the FMR school and 187 children aged from 6 to 8 years of the control school completed the baseline survey. Children from the FMR school rinsed with 0.05% sodium fluoride everyday under supervision, while those from the control school did not. Adjusted caries preventive fraction (CPF) for 2 years were calculated to evaluate the effect of the FMR program. Result: After 2 years, 288 schoolchildren remained in the study. Decayed, missing or filled permanent teeth (DMFT) and index of the FMR and the control schools at baseline were 0.11 and 0.12, respectively, and the average DMFT increment of the FMR and the control schools after 2 years were 0.35 and 0.65, respectively. The adjusted CPF of DMFT was 48.5%. Conclusion: These findings show that a school-based FMR is an effective caries preventive program in a socially deprived community with poor infrastructure for oral health.

Mechanical removals in decayed teeth have been performed using drill and sharp hand instruments. These methods have some disadvantages such as pain, local anesthesia and overextended cavities Therefore chemo-mechanical excavation of dentin carious lesions has been introduced. The purpose of this study was to evaluate the efficacy of traditional mechanical methods using burs and chemo-mechanical methods (Carisolv) of caries dentin. Mechanical caries removal was carried with low speed round bur Chemo-mechanical caries excavation was performed with Carisolv (Medi-team), using the Carisolv hand instruments. The mean time to remove caries with two different methods was evaluated and the data analyzed with SPSS software (ver 11.5) by t-test (p < 0.05). For histomorphometry of caries removal were also carried with mechanical or chemo-mechanical (Carisolv) methods from 20 extracted caries permanent molars. Complete caries removal was verified with a $\#$23 sharp explorers, Caries Detector (Kuraray Co. Japan), and standard apical radiography. 1. Chemo-mechanical method was taken more times than mechanical method (1.5 fold) (p < 0.05) 2. Excavation for caries took more time for molar lesion than premolar lesion, and the least time was taken to remove the caries in incisor lesion (p < 0.05). 3. There were no significant differences to remove the caries between the maxilla and mandible (p > 0.05). 4. The remaining carious dentin was detected after the ckemo-mechanical removal of the carious dentin, and no smear layer were seen after the mechanical and chemo-mechanical removal of the carious dentin.

The purpose of this study is to investigate the retention and caries prevention practical effectiveness of fissure sealant and regular checkup with cost-benefit analysis. The data of this study is based on "2000 The Survey of Korean Oral Health" by Ministry of Health & Welfare. This study is to investigate cost-benefit analysis on proper treatment for the decayed, in case of operating fissure sealant on molars at 1 year after eruption of permanent teeth. The obtained results were as follows: (1) Cost-benefit analysis on fissure sealant in 6-75 year old 43,736 thousand Korean people reveals that cost of fissure sealant is 1,610,994 million won and benefit is 69,460,691 million won. (2) Benefit of fissure sealant is 39.51 times as much as cost of fissure sealant. (3) Cost of twice in a year regular checkup is 2,678,544 million won. Indirect cost of regular checkup is 2.6 times as much as direct cost. (4) Cost of fissure sealant and twice in a year regular checkup is 4,289,538 million won, and benefit is 69,460,691 million won. Benefit of fissure sealant and twice in a year regular checkup is 16.2 times as much as cost.

This study carried out to provide basic educational material of primary school children to improve the children's oral health by oral health checkup and survey over 215 students in the first grade and the fourth grade at the primary school in Hwaseong city. The collected data were analyzed by SPSS Win 12.0 program 1. The rate of students who have decayed permanent teeth was 57.2%, and there seemed to be a significant difference between the two genders showing 61.6% for male students and 53.3% for female students. Also 1st grade showed 56.0% and 4th grade 58.1% respectively. 2. The male students who claimed 'bleeding gum' against questions about oral illness experiences were 15.7% whereas female students were 28.0%. There was a significant difference(p<0.05) by the gender. 3. The 4th grade students who said 'Toothache while eating cold food' about questions of oral symptoms appeared as 19.4% and 1st grade students were 8.8%. Also there was a significant difference(p<0.05) by the grade. 4. Regarding oral health improvement behavior, there were significant differences in frequency of toothbrushing a day, the number(p<0.05) of eating snacks a day and the number(p<0.01) of experience of visiting dental clinic(p<0.01). 5. About oral health behavior frequency of daily toothbrushing was found as twice(50.2%), twice of eating snacks a day(70.2%), using fluoride toothpaste 60.9% and visiting a dental clinic(60.0%), were shown as the highest numbers.
