口腔预防常见考点总结 Presented by Kurtis.D in 2011 Part 1, oral epidemiology Oral epidemiology: It is the field of stomotology concerned with the determination of causes, incidence, and characteristic behavior of oral disease outbreaks affecting human populations. It includes the interrelationships of host, agent and environment as related to the distribution and control of disease. Silness and Loe’s plaque index: It is an index to describe the oral health and periodontal disease prevention by score the plaque thickness instead of area. Pathfinder survey: It is a epidemiology survey method. It is suitable for understand the health condition of a group in a short term and estimate the needed resources. Kappa: Kappa is a value to check the data reliability. When the kappa is less than 0.40, the reliability is unreliable. 0.41-0.60 is moderate reliability. 0.61-0.80 is good reliability, 0.81-1.0 is complete reliable. 口腔流行病学的作用 Function of oral epidemiology 1, 描述人群口腔健康与疾病的分布状态 2, 研究口腔疾病的病因和影响流行的因素 3, 用于研究疾病预防措施并评价其效果 4, 用于口腔疾病监测 5, 制订口腔卫生保健规划并评价其发展 口腔流行病学研究方法 Research methods of oral epidemiology 1, Descriptive epidemiology Cross-sectional study Longitudinal study Studies analyzing available routine data-sets 2, Analytic epidemiology Case-control study Cohort study 3, Experimental epidemiology/ Field trial/ Intervention study Field trial Community intervention trial Clinical trial 列举龋病指数（至少5个） List and discuss at least 5 caries index 1, DMF index It is the most common used index to describe caries. It records amount of the decayed, missing and filled teeth/teeth surface. 2, dmft index It is used to describe the deciduous teeth caries. 3, Caries average/caries surface average It describes the average amount of the decayed, missing and filled teeth/teeth surface. 4, Caries prevalence rate It describes the frequency of caries cases in a group of people in a survey period. 5, Caries incidence rate It describes the frequency of new caries cases in a group of people in at least one ye
