The purpose of this study was to reveal analyze the relationship between status of participation in an oral health care program and oral health outcomes among patients in Korea, and to evaluate the results to provide evidence regarding the feasibility of widespread implementation of the program. Patients were designated as either cooperative or non-cooperative with the oral health care program and were assigned to each group accordingly. Modified dental hygiene process (M-DHP) of the oral healthcare program was modified to form the dental hygiene process. The study included 48 patients at a dental clinic in Busan, Korea. Questionnaires were used to collect information on oral health behavior (OHB), clinical examination was used to record bleeding on probing (BOP) and O'Leary index, and phase microscopy was used to identify microorganisms. Differences between groups were evaluated using repeated measures ANOVA. Our results showed that the group cooperative with the oral health care program showed greater improvement in OHB, BOP, and O'Leary index than the non-cooperative group. Second, patient satisfaction with the M-DHP was very high, particularly for content and the friendly nature of the staff. The cooperative group showed greater improvement in oral health than the non-cooperative group for all metrics. Our results suggest that this low-coste program, if implemented, would be actively accepted and utilized in dental clinics.

Objectives : In general, the active of volatile compounds which become usually known as the principal ingredient of bad breath is closely connected with temperature. In this study, an investigation was made into the correlation between oral malodor and the temperature of rinsing water. Specifically, an analysis was made of saliva in rinsing water with relation to amount, flow and pH. In addition, a calculation was made of O'Leary index. The results are expected to be basic data for oral malodor reduction plans. Methods : A total of 30 women who are in their 20s without any systemic disease and teeth braces and non-pregnant were chosen for the study. The research was carried during 3 weeks from 28 Mar to 11 Apr in 2011. Results : Saliva was not significantly affected by the temperature of rinsing water, in connection with saliva amount, saliva flow and saliva pH. The O'Leary index and oral malodor was the highest in warm water, but the subjects preferred rinsing with cold water. Conclusions : In conclusion, oral malodor was found to be reduced in inverse proportion to the temperature of rinsing water. Thus, it is recommended to rinsing water with warm water after tooth brushing.

Purpose : The purpose of this study was to compare the plaque removal effects of vacuum oral cleaner developed for the patients with limited mobility with those of manual toothbrushes and high pressure injection oral cleaner (dental water jet). Meterials and methods : Thirty human subjects were measured with Patient Hygiene Performance index (PHP index) and O'Leary index before and after the use of toothbrush, high pressure injection oral cleaner and vacuum oral cleaner. These three different oral hygiene methods were conducted with seven-day intermittence. Then the statistical analysis was carried out to define plaque removal rate of three different oral hygiene methods (${\alpha}=.05$). Results : According to the efficacy analysis of plaque removal before and after the oral cleaning using each of three methods, significant reduction in plaque after the treatment compared to the previous state when using toothbrush, high pressure injection oral cleaner, and vacuum oral cleaner was observed (P < 0.001). PHP index of tooth brushing was higher than that of the high pressure injection oral cleaner, while PHP index of vacuum oral cleaner did not show significant difference from either of the other two methods. There was no significance difference in O'Leary index among the three methods. Conclusion : Effect of plaque removal using the vacuum oral cleaner is comparable to that of manual tooth brush or high pressure injection oral cleaner, so it will be helpful for self-oral hygiene care of the patients with limited mobility.

교정치료 중 구강 내 환경 변화를 파악하기 위하여 교정치료 시작 후 24개월까지의 임상적 구강위생지수 및 타액, 구강 내 미생물의 변화양상을 평가하였다. 30명의 환자를 대상으로 하여, 임상적 구강위생지수(DMFS [decayed, missing and filled surfaces], O'Leary's plaque index, plaque pH), 타액의 변화(비자극/자극시의 타액량, 완충능(buffer capacity), pH, 잠혈(occult blood)류량, 구강 내 미생물(Streptococcus mutans, Lactobacillus) 변화를 파악하였다. 추가적으로 설문지를 이용하여 구강위생관리 및 식습관을 평가하였다. 분산분석, 회귀분석 및 Spearman의 상관분석을 통해 데이터를 분석하였다. 교정치료 도중 DMFS 값은 유의성있게 증가한 반면, plaque index는 감소하였고, plaque pH는 산성을 나타내었다 (p = 0.23). 비자극 시 타액량은 치료 중 유의성있게 변화하였으며 (p = 0.13), 자극 시의 타액량은 여성에서 장치 부착 이후 증가하는 양상을 보였다. Buffer capacity는 남성에서 치료 도중 감소되었으며, 타액의 pH는 유지되었다. 구강 내 미생물 및 잠혈류량은 고위험 수준까지 증가하였으며 성별의 차이는 나타나지 않았다 (p > 0.05). 치료 전 plaque와 구강위생용품의 사용 (r = 0.429; p = 0.018), 최종 DMFS와 비자극 시의 타액량 (r = -0.372; p = 0.043) 간에 뚜렷한 상관관계가 확인되었다. 교정장치의 부착으로 인해 구강 내 미생물은 증가하고, plaque pH는 산성화되어 치주조직의 손상이 일어나게 되었다. 또한 Buffer capacity는 변하지만, 치료 기간중의 타액의 pH는 유지되었다.

Purpose: The purpose of this study was to evaluate the efficacy of the modified plaque score (MPS) for assessing the oral hygiene status of periodontitis patients. Methods: A total of 116 patients were included in this study. After evaluation of the $L{\ddot{o}}e$ and Silness gingival index (GI), Silness and $L{\ddot{o}}e$ plaque index (PlI), O'Leary plaque control record (PCR), and MPS, patients were randomly assigned to either a conventional tooth brushing instruction (C-TBI) group (n=56) or a professional intraoral tooth brushing instruction (P-TBI) group (n=60). The MPS and clinical parameters were re-evaluated after scaling and a series of root planing. The convergent validity of MPS with the PlI and PCR was assessed. The measurement time for MPS and PCR was compared according to the proficiency of the examiner. Results: After root planing, the GI, PlI, PCR, and MPS improved from their respective baseline values in both groups. Three different plaque indices including the MPS, showed significant differences between the C-TBI group and the P-TBI group after root planing. The MPS showed significant concurrence with the PCR and PlI. The mean time for PCR measurement was $2.76{\pm}0.71$ times longer than that for MPS measurement after 2 weeks of training. Conclusions: MPS seems to be a practical plaque scoring system compared with the PlI and PCR. These findings suggest that repetitive plaque control combined with an easily applicable plaque index (MPS) may facilitate more effective oral hygiene education and improved periodontal health.
