龋齿是我国最常见的疾病。我国大约有半数人口患龋齿,龋齿数约十亿个。据全国对13万多名学生进行口腔病调查结果证实:学生恒牙龋齿发病率,城市为40.54%,农村为29.7%。乳牙龋齿发病率,城市为79.6%,农村为58.5%。可以看出,学龄前儿童乳牙龋齿发病率相当高,特别是生活条件比较优越的城市儿童。
Dental caries is the most common disease in our country. About half of China’s population is suffering from dental caries, about a billion caries. According to the survey of more than 130,000 students in the country, the incidence of dental caries in students was 40.54% in urban areas and 29.7% in rural areas. The incidence of deciduous dental caries was 79.6% in urban areas and 58.5% in rural areas. As can be seen, the incidence of deciduous dental decay in preschool children is quite high, especially in urban children with better living conditions.
