本文报告了45个正常儿童,25个患膀胱纤维变性的儿童和25个患哮喘病的儿童的牙结石形成情况。6岁以下的正常儿童有牙结石的只有9%,在7—9岁之间约占18%,10岁以上儿童约有43%。钙的浓度在患囊性纤维性变与患哮喘病的儿童中是相似的。可是都比正常儿童在分泌中钙的浓度有明显的增高。在患囊性纤维性变的儿童中,其磷质也有明显增高。而在患哮喘病的儿童中,其磷质是较少限度的增加。在所有儿童中关于钠、钾以及流动率,没有什么差别。在6岁以下的儿童,其牙石发生率低,可能是由于乳牙其釉质的特殊性与恒牙者有区别。儿童中牙结石多发生于下前牙,而少发生于上后牙。在正常人的颌下腺唾液中所含的钙比腮腺唾液中几乎多二倍。患囊性纤维性变与哮喘病儿童中其牙石
This article reports on the formation of dental calculus in 45 normal children, 25 children with cystic fibrosis and 25 children with asthma. Normal children under 6 years old have only 9% of calculus, about 18% of people aged 7-9, and 43% of children over the age of 10. The concentration of calcium is similar in children with cystic fibrosis and with asthma. However, compared with normal children in the secretion of calcium concentration was significantly increased. In children with cystic fibrosis, the phosphorus is also significantly higher. In children with asthma, however, their phosphorus levels are marginally increased. There is no difference in all children regarding sodium, potassium and mobility. In children under the age of 6, the incidence of dental calculus is low, probably due to the special nature of deciduous teeth and permanent teeth are different. Tooth in children and more occurred in the lower anterior teeth, and less occurred in the upper teeth. In normal submandibular gland saliva, calcium is almost twice as much in parotid saliva.
