从19世纪到20世纪这100多年中,大量的科学研究证实,糖确实是引起龋齿的一种危险因素。另一方面,有关研究也证实了龋齿是由多种因素引起的一种感染性疾病。在龋齿发病过程中,细菌是主要致病因素之一。致龋细菌的主要作用之一是利用摄人口内的糖,经发酵后产生酸,引起口腔内PH值下降,使口腔呈酸性环境。若频繁摄人甜食,致口腔内PH值持续下降至临界值以下,使牙釉质不断遭受到酸的侵蚀,便引起脱矿,从而导致龋齿的发生。
From the 19th century to the 20th century, more than 100 years, a large number of scientific studies have confirmed that sugar is indeed a risk factor for dental caries. On the other hand, the study also confirmed that dental caries is caused by a variety of factors, an infectious disease. Bacteria are one of the major causative agents during the development of dental caries. One of the major effects of cariogenic bacteria is the use of sugar in the mouth, resulting in acid after fermentation, causing the oral pH value decreased, so that the oral acidic environment. If the frequent intake of sweets, causing the oral pH value continued to drop below the critical value, the enamel continue to suffer from acid erosion, it will cause demineralization, resulting in the occurrence of dental caries.
