众所周知,牙硬组织极易受到矿物酸的作用。某些学者指出矿物酸在龋病发生中的作用。但是,长期工作于矿物酸蒸气所污染空气里的人们与矿物酸无接触的人们牙齿的龋患率相比并不增高。本研究的目的是确定矿物酸作用下龋病的发生和发展情况。著者进行了103支白鼠的实验研究。把鼠分成四组。一为实验组,其余三组为对照组。实验组(21支)饲养于被盐酸蒸气污染的空气里,并给以引起龋病病
As we all know, tooth hard tissue vulnerable to the role of mineral acids. Some scholars pointed out the role of mineral acids in the occurrence of dental caries. However, people who work long hours in the air polluted by mineral acid vapor have a lower caries rate than those who have no contact with mineral acids. The purpose of this study was to determine the occurrence and development of dental caries under the action of mineral acids. Author conducted 103 experimental studies in rats. Divide the rats into four groups. One for the experimental group, the remaining three groups for the control group. The experimental group (21) was kept in air contaminated with hydrochloric acid vapor and given to cause caries disease
