To improve oral hygiene management, the effects of toothbrush training on general oral hygiene based on the simplified oral hygiene index(S-OHI) and degree of knowledge about toothbrushing were examined. Pre-and post-training changes in the S-OHI (lower score = better oral health status) showed a significant decrease in score in all variables (gender, age, marital status, occupation, and level of education).Pre- and post-training changes in the degree of knowledge about toothbrushing showed a significant increase. Negative correlations between the S-OHI, oral health status, and degree of knowledge about toothbrushing and the S-OHI and the Decayed, Missing, Filled (DMF) index (the better the oral cavity environment, the lower the DMF index) were observed. Positive effects of repeated toothbrush training on the maintenance of healthy oral cavity environment and continuous oral health management were observed, as reflected by the correct toothbrushing-related knowledge and skills.

Objective : This study was performed in order to provide basic data for halitosis prevention and establish a device to efficiently eliminate halitosis and to analyze the factors that affect the halitosis. Methods : Oral examination on the Gingival index, CPITN, Tongue Plaque index, and OHI-S as well as halitosis measurement among 293 rural residents. Results : Gingival index was high at mild on female and at moderate on male(p=0.025). Sorting the result by age, mild was 54.1% in the 40s, and moderate was 49.5%, 42.0% and 70.0% each in the 50s, 60s, and the 70s(p=0.005). The need for dental plaque management was 100%. The need for scaling was high with 78.3%, 93.0%, 89.9%, and 90.0% each for the 40s, 50s, 60s, and 70s. The need for complex periodontal treatment was also high with 32.4%, 47.5%, 48.7% and 60.0%, each for the 40s, 50s, 60s, and 70s(p=0.050). The highest bad condition for OHI-S was 69.5%, and good being 18.9%, and very bad being 11.6%. For moderate tongue plaque index was 74.4% as the highest. As the level of education increased, the slight tongue plague was increased, but in contrast, the moderate and higher tongue plague index was decreased(p=0.010). OG under 50ppm was 61.1% on male and OG over 50ppm was 50.9% on female(p=0.041). In OG over 50ppm, CPITN was 52.1% and 41.9% in scaling and complex periodontal treatment group(p=0.018). OHI-S, in bad and very bad condition with OG, over 50ppm, was 48.7% and 46.9%(p=0.019). The higher tongue plague index showed significant amount of increase at OG and EG above 50ppm(p=0.006). $NH_3$, as the tongue plaque index increased, the wider range of distribution was shown(p=0.000). As for the multiple regression analysis result, there have been selected females and tongue plaque index as factors affecting OG. There have been selected age and tongue plaque index as factors affecting EG and there have been selected females as factors affecting on $NH_3$. Conclusions : With the aforementioned results in mind, the status of halitosis among rural residents is considered to bare a close relation with oral environments. we have to focus on correct tooth brushing methods and tongue brushing, with using tongue cleaner to remove fur of tongue plaque. Also, in order to analyze exactly the factors of individual halitosis, we need continuous and systematic study.

The present study purposed to prevent oral diseases and to improve oral health in children. For this purpose, we selected 70 cases who are 5~7 years old preschoolers at the kindergarten affiliated to G College in Gyeongsangbukdo, and analyzed the general patterns of oral care and the relation of the patterns with dental plaque and deciduous dental caries in the children. Specifically, we conducted oral examination and applied pit and fissure sealant according to the eruption of deciduous molar and first molar. In addition, we executed the 1st and 2nd tooth brushing instruction (TBI), and surveyed S-OHI and PHP twice. Excluding 14 preschoolers who did not appear in the 2nd survey, we performed the study with 56 preschoolers and drew conclusions as follows. 1. The number of decayed or missed or filled teeth among deciduous teeth was 3 or more in 42.9% of female children, and 46.4% of male children, so male children showed a slightly higher rate. 2. The degree of dental plaque formation was $1.64{\pm}1.22$ among the surveyed children. 3. The oral health index was lower after TBI than before in all the children (P<.001). 4. Change in the oral health index was particularly larger in 7 year old female children (p<.005). 5. The patient hygiene performance index was lower after TBI than before in both the buccal surface and lingual surface of the children (p<.005). 6. The patient hygiene performance index was lower after TBI than before in all of male children's teeth except the right maxillary first deciduous molar (p<.001).

This study used 3 kinds of experimental toothpaste prepared with different contents of SLS, i.e. A (0%), B (1.1%), C (2.2%). These 150 subjects were subdivided again into three groups. After 4 weeks application of the three kinds of toothpaste, it was found that there were differences in dental plaque test (PHP) among the 3 groups; that is; a higher SLS content was associated with a lower PHP index. In addition, it was found that all 3 groups showed a reduction in simplified oral hygiene index (OHI-S). After 4 weeks application of the three groups of toothpaste, it was found that a higher SLS content was associated with a lower salivary flow, but there was no significant variation in salivary mucosity and pH. Further, it was found that SLS was negatively correlated with salivary flow, which supports the theory that SLS may induce xerostomia.

Objectives: The objective of the study was to investigate the oral health index in orthodontic patients by dividing the patients into two groups; the OHCP (Oral Health Care Program)group and the control group. Methods: The subjects in Busan were divided into two groups, including the OHCP group (205 patients) and the control group (119 patients), during orthodontic treatment that took place from October 2015 to October 2016. The oral health index was subdivided into three groups according to the oral interest level of the OHCP and control groups. The oral health index used was Simplified Oral Hygiene Index (S-OHI) and Community Periodontal Index of Treatment Needs (CPITN). Results: When the degree of oral interest was compared, he OHCP group before application and after application saw a significant difference (p<0.001) in all the variables except the S-DI. Meanwhile, the control group saw no significant difference in most variables. after OHCP application, The OHCP group was significant differences in all variables (p<0.001), and the control group was no significant difference in most variables. Conclusions: Oral hygiene management for orthodontic patients should be systematically and professionally programmed differently from that for general dental treatment patients. As such, dental hygienists should take this into consideration and proactively develop and research programs similar to OHCP for orthodontic patients.

The purpose of this study was to provide basic information for improving oral health and dental hygiene through comprehensive dental hygiene care. The subjects in this study were 54 patients who had been treated for 4 weeks in clinic of the Dental Hygiene Department of G University under comprehensive dental hygiene control and care and measured their oral condition, intensity of oral malodor, Simplified Oral Hygiene Index (S-OHI), and Modified Personal Hygiene Performance Index (PHP-M), and surveyed their oral health behavior and oral health consciousness. The results of the study were as follows: 1. The intensity of malodor decreased by 16.49ppb from 75.33ppb on the first visit to 50.84ppb on the last visit when the comprehensive dental hygiene care had been finished. 2. As to change in S-OHI according to gender between the first visit and the last visit for comprehensive dental hygiene care, S-OHI decreased from 2.89 on the first visit to 1.16 on the last visit, and the difference was statistically highly significant. 3. As to change in PHP-M index by tooth according to gender and age between the first visit and the last visit, PHP-M index of the first 6 teeth decreased very significantly from 0.50 on the first visit to 0.34 on the last visit. 4. As a whole, significant improvement was observed in every tooth. According to gender and age, PHP-M index for Tooth No. 26, 36 and 32 decreased significantly in men and women, and those aged under 30 and those aged 30 or over, but for Tooth No. 13 and 15 and 44 it decreased significantly only in men and those aged 30 or over, and for Tooth No. 44 only in men. As presented above, the oral health behavior and oral health consciousness of the visitors to the oral prophylaxis practice room are very important, and it is necessary to enhance their interest in and knowledge of how to improve oral health. Furthermore, comprehensive dental hygiene care required for improving the visitors' oral health.

Objectives : The objective of this study was to compare oral health behaviors and oral health indices between regular scaling group and irregular scaling group. Methods : This study was performed at M Dental Clinic in Busan on 352 dental patients treated between January 2014 and June 2015 using V6.0 software and medical interviews. The 352 patients were divided into 3 groups and oral health behavior (OHB) and oral health indices were compared. Results : The OHB scores significantly differed among Groups C and A. Group C had the lowest number of "Bad" scores for the Simplified Debris Index (S-DI), Simplified Calculus Index (S-CI), and Simplified Oral Hygiene Index (S-OHI). Groups B and A had the lowest number of "Excellent" scores. Group C had the lowest bleeding on probing (BOP), calculus rate (CR) and decayed teeth (DT). Furthermore, Group C had the highest number of missing teeth (MT) and filled teeth (FT). Conclusions : Patients who underwent regular scaling had the highest OHB and oral health index scores. This emphasizes the importance of regular scaling for prevention and early detection of oral disease.
