Degree of mineralization of enamel is one of the parameters mediating in its resistance to acid dissolution and at the stage of teething, the enamel is immature and, therefore, present a higher susceptibility to dental caries. This investigation was carried out with 38 preschool children (means = 5.5 years) and 19 children coursing second grade (means = 7.6 years). They were treated with 10 oral rinsing with mineralizing solution in order to evaluate its effect on enamel resistance to acid dissolution; colorimetric technique was used for such purpose. A study in vitro was also performed in impacted third molars extracted by surgery and to two halves of the clinical crowns of such molars the treatment was applied; the other two halves were taken as control. Increase of enamel resistance found was 18.6% in the study of preschool children and 34.6% in the children attending to second grade school. In both groups, 89.5% of the children increased enamel resistance and in the study in vitro increaser enamel was 14.9%.. It is concluded that the use of risings with mineralizing solution at the outbreak of permanent teething increase, significatively, enamel resistance, and that at the age of seven the enamel is still immature, thus its resistance to acid dissolution can be also increased using mineralizing solution.
牙釉质的矿化程度是介导其抗酸溶解能力的参数之一,在出牙阶段,牙釉质不成熟,因此对龋齿的易感性更高。本研究对38名学龄前儿童(平均年龄5.5岁)和19名二年级儿童(平均年龄7.6岁)进行。为了评估矿化溶液对牙釉质抗酸溶解能力的影响,他们接受了10次用矿化溶液的口腔冲洗治疗;为此使用了比色技术。还对手术拔除的阻生第三磨牙进行了体外研究,并对该磨牙临床牙冠的两半进行了治疗;另外两半作为对照。在学龄前儿童的研究中,发现牙釉质抗酸溶解能力提高了18.6%,在二年级儿童中提高了34.6%。在两组中,89.5%的儿童牙釉质抗酸溶解能力提高,在体外研究中,牙釉质抗酸溶解能力提高了14.9%。得出的结论是,在恒牙出牙开始时使用矿化溶液冲洗可显著提高牙釉质的抗酸溶解能力,并且在7岁时牙釉质仍然不成熟,因此使用矿化溶液也可提高其抗酸溶解能力。
