Dental plaque resides passively at a site and makes an active contribution to the maintenance of health. The bacterial composition of plaque remains relatively stable despite regular exposure to minor environmental stress. This stability, homeostasis is due to a dynamic balance of microbial interactions. However, the homeostasis can break down, leading to shifts in the balance of the microflora. This change can be a sign of initial dental caries. It is proposed that disease can be prevented or treated not only by targeting the putative pathogens but also by interfering with the processes that drive the breakdown in homeostasis. It is essential to understand the plaque as a mixed species biofilm. In this essay I reviewed an extension of the caries ecological hypothesis to explain the relation between dynamic changes in the phenotypic/genotypic properties of plaque bacteria and the demineralization and remineralization balance of the dental caries process. We will have the strategies to impact significantly on clinical practice as understanding dental biofilm.

치과 임상실습에서의 손의 수세와 장갑착용의 미생물 차단효과에 대해 알아보기 위하여 수세하지 않고 장갑을 착용하는 경우, 비누와 데톨로 수세한 후 장갑을 착용한 경우로 구분하여 손과 장갑의 일반 세균 수를 측정하였고 그 결과는 다음과 같다. 수세하지 않고 장갑을 착용한 손과 장갑에서는 $9.938{\time}10^3CFU/ml$, 비누로 수세한 후 장갑을 착용한 손과 장갑에서는 $9.44{\time}10^3CFU/ml$, 데톨로 수세한 후 장갑을 착용한 손과 장갑에서는 $6.58{\time}10^2CFU/ml$의 일반 세균이 검출되었다. 비수세의 경우 가장 많은 수의 일반 세균이, 비누로 수세한 경우에는 비수세와 유사한 일반 세균 수가 검출되었으나 데톨로 수세한 경우의 일반 세균 수는 급격히 감소하여 비누로 수세하는 것은 병원성 미생물 차단에 효과적이지 않지만 데톨로 수세하는 것은 일반 세균 수 감소에 효과적임을 알 수 있었다. 또한 수세하지 않고 장갑을 착용한 경우와 수세한 후 장갑을 착용한 모든 경우에서 일반 세균 수가 감소하여 장갑의 미생물 차단 효과가 명확하게 보여졌다. 비누와 데톨로 수세 후 장갑을 착용한 경우 일반 세균 수는 장갑 착용 3시간이 경과하여도 변화가 적었지만 수세하지 않고 장갑 착용한 경우 처음 장갑을 착용한 3시간 이후부터 일반 세균의 수가 다시 증가하는 경향을 보여 적어도 장갑 착용 3시간 이후부터는 같은 환자의 시술 중이라도 새로운 장갑으로 교체를 하는 것이 미생물 감염 발생 가능성을 최소화하기 위해 효과적임을 알 수 있었다.

Objectives: This study investigates dropout intention and the structural relationship between the dental hygienist role and satisfaction with the study major perceived by dental hygiene students. Methods: A survey was conducted on 269 dental hygiene students. The survey items covered general characteristics, department choice motivation, the desirability of dental hygienist career, practice clinical experience, perception of dental hygienist role, satisfaction with study major, and dropout intention. Independent sample t-test, one-way ANOVA, Mann-Whitney U test, multiple linear regression analysis, and structural equation modeling were used for statistical analysis. Results: The dropout intention level of dental hygiene students was 2.4 out of 5.0. Satisfaction with study major partially mediates perception of dental hygienist role and dropout intention (direct effect=0.182, p=0.024, indirect effect=-0.437, p=0.010). Perception of dental hygienist role (β=-0.255, p=0.010) and satisfaction with study major (β=-0.661, p=0.010) showed a negative relationship with dropout intention. The factor most affecting dropout intention was satisfaction with study major. Dropout intention was high when selecting a major based on external motivations (β=-0.448, p<0.001). Conclusions: Perception of dental hygienist role and satisfaction with study major directly or indirectly affect dropout intention. Therefore, improving satisfaction with study major and improving the perception of dental hygienists will help reduce dropout intention.

Objectives : The aim of the trial was to study the effect of plaque control(tooth brushing instruction) for oral health improvement on periodontitis patients. Methods : 30 patients(35~65 years) with advanced periodontal disease were subjected to a baseline examination including assessment of oral hygiene status(O'leary index), gingival condition(bleeding). the assessment were repeated after 2, 4, 6 weeks. cognitive, behavioral and clinical outcomes were assessed in the primary care setting by questionnaire and clinical oral examination. Results : The oral hygiene status expressed as the individual mean percentage of tooth surfaces with plaque 59.3% at baseline and 21.2% after 6 weeks(p<0.001). The gingival bleeding status expressed as the individual mean point of interdental papilla 3.8 at baseline and 1.9 after 6 weeks(p<0.001). Also, the patients self-assessment about correct tooth brushing behavior was 3.9(5-point likert scales), satisfaction of plan practices 4.1(5-point likert scales), efficacy of tooth brushing instruction 8.7(10-point likert scales). Patients wanted to continuous participation. Conclusions : A verification of effect after individualized oral health instruction and repeated dental plaque control represented to significance on plaque control score, oral care practice and oral health recognition. The important oral care step against periodontal disease is to establish good oral health habits. Also, oral health behavior recognition is more important for the practice of oral health. Therefore professional plaque control and tooth brushing instruction absolutely need in improving oral health.
