Almost everyone on the planet has suffered dental caries. It is why dental caries are considered a public health problem. The anticariogenic efficacy of dental sealants for pits and fissures is related to their retention. Air abrasion and acid etching are two current techniques for applying pit and fissure sealants. Our objective was to compare the efficiency of retention a pit and fissure sealant in primary dental organs pre-conditioned with acid etching and air abrasion.
A descriptive, comparative study was conducted in 40 primary dental organs randomly divided into two groups for conditioning the enamel with one or the other technique. Sealants and double-standard mesh for brackets with double ligatures were applied to test shear bond strength with an Inströn testing machine. Student's t-test was used to compare the shear-peel bond strength exerted by the two techniques.
The average traction tolerated in the group treated with air abrasion was 2.62 kgf, and in the group treated with acid etching was 3.55 kgf, with statistically significant differences (p=0.007).
Acid etching demonstrated greater efficiency than air abrasion for retention of dental sealant for small pits and fissures in primary teeth.
地球上几乎每个人都患过龋齿。这就是为什么龋齿被视为一个公共卫生问题。窝沟封闭剂的防龋效果与其保留率有关。空气喷砂和酸蚀是目前应用窝沟封闭剂的两种技术。我们的目的是比较在经酸蚀和空气喷砂预处理的乳牙中窝沟封闭剂的保留效率。
进行了一项描述性比较研究，将40个乳牙随机分为两组，分别用一种技术对釉质进行预处理。应用封闭剂以及带有双结扎丝的双标准托槽网来通过英斯特朗试验机测试剪切粘结强度。采用学生t检验比较两种技术施加的剪切-剥离粘结强度。
空气喷砂处理组的平均耐受拉力为2.62千克力，酸蚀处理组为3.55千克力，具有统计学显著差异（p = 0.007）。
对于乳牙中小窝沟的封闭剂保留，酸蚀显示出比空气喷砂更高的效率。
