据作者的资料,约有4.5%的小儿患佝偻病,并且发现患佝偻病的小儿的龋齿损害指标低于无佝偻病的小儿,和以前的文献资料相反。对3～18岁的小儿和少年有计划地进行口腔检查,划分出有龋齿和无龋齿两组,每组507例,两组年龄分布相似。检查结果,无龋齿组,患佝偻病者比例高,占6.51±1.09%;有龋齿组,患佝偻病者比例低,占2.56±0.77%。患佝偻病的学龄前儿童,龋病较轻;有龋齿组3～7岁小儿的失
According to the authors, about 4.5% of children have rickets, and children with rickets have been found to have lower rates of dental caries damage than rickets-free children, as opposed to previous literature. Oral examination was planned in children and adolescents aged 3-18 years. Two groups of caries-free and tooth-free caries were divided into two groups of 507 cases each with similar age distribution. The results showed that the caries-free group had a high proportion of patients with rickets, accounting for 6.51 ± 1.09%. The caries-bearing group had a low rate of rickets, accounting for 2.56 ± 0.77%. Pre-school children with rickets, caries less; dental caries group 3 to 7-year-old children's loss
