龋齿是人类的多发病、常见病之一。它的发生与多种因素有关。近代科学研究表明,适量的氟是人体建造牙齿和骨骼的必要元素。由于氟的理化特性,能抑制口腔中的致龋细菌,抑制食物发酵生酸,具有防止龋齿的作用。本文仅就氟对龋齿患病率的影响调查小结如下。调查方法一、调查对象:为全县中、小学校学生。二、检查指标:1.氟斑牙:根据《北方地方性氟中毒防治标准试行草案》划分氟斑牙分型分度。但是由全身性疾病、营养障碍或局部感染造成的牙齿发育不良、“四环素牙齿”、牙齿外伤等
Dental caries is one of the most common diseases in humans. It occurs with a variety of factors. Modern scientific research shows that the right amount of fluoride is an essential element of the human body to build teeth and bones. Due to the physicochemical properties of fluorine, it can inhibit the cariogenic bacteria in the oral cavity, inhibit the fermented acid from food, and has the effect of preventing dental caries. This article only fluorine on the prevalence of dental caries survey summary is as follows. Survey methods First, the survey: for the county primary and secondary school students. Second, the inspection indicators: 1. Dental fluorosis: According to the “Northern endemic fluorosis prevention and control of the draft standard” classification of dental fluorosis classification. However, dental stunting caused by systemic diseases, nutritional disorders or local infections, “tetracycline teeth”, dental trauma, etc.
