To analyze the clinical behavior of 2 pit and fissure sealants through clinical/computerized evaluation.
Occlusal sealants were placed on maxillary and mandibular first and second premolars according to a split-mouth design. All premolars were sealed with either Concise (3M Espe) or Prisma Shield (Caulk/Dentsply) sealant agents. A hematoxylin-based staining solution was applied on the occlusal surface 7 days, 18 months, 36 months, and 11 years after occlusal sealing to allow checking of the sealant material on the surface. At each analysis time all occlusal surfaces were photographed, and the photographs corresponding to each time period were analyzed with SigmaScan 4.0 Software. The alterations of the sealed area of each sealant were analyzed with the software and recorded. Next, the measurements of the areas were tabulated and analyzed according to each period. Analysis of variance (ANOVA), with parts subdivided into time, and the t test, with a significance level of 5%, were used.
The greatest sealed area was maintained by the sealant Concise. However, over the course of 11 years, all sealants began to show the same level of alteration in sealed area.
The sealing materials showed alteration in sealed area over time, but they were efficient in controlling caries lesion formation on premolar pits and fissures.
通过临床/计算机化评估分析两种窝沟封闭剂的临床性能。
根据双侧对照设计，在上颌和下颌第一、二前磨牙上放置窝沟封闭剂。所有前磨牙均用Concise（3M Espe）或Prisma Shield（Caulk/Dentsply）封闭剂进行封闭。在封闭后7天、18个月、36个月和11年，在咬合面上应用苏木精染色液，以便检查表面的封闭剂材料。在每次分析时，对所有咬合面进行拍照，并使用SigmaScan 4.0软件分析与每个时间段相对应的照片。用该软件分析并记录每种封闭剂封闭区域的变化。接下来，将各区域的测量值列表并按每个时间段进行分析。采用方差分析（ANOVA），将部分细分为时间，并采用t检验，显著性水平为5%。
封闭剂Concise保持了最大的封闭面积。然而，在11年的过程中，所有封闭剂在封闭区域开始显示出相同程度的变化。
封闭材料的封闭区域随时间发生变化，但它们在控制前磨牙窝沟龋损形成方面是有效的。
