From the dental literature, it is clear that the clinical application of pit-and-fissure sealants is a necessity in pedodontics. The choice between the non-invasive and the invasive techniques remains a matter of debate. In this SEM study, a comparison is made between different types of burs in order to obtain the best fissure preparation before the application of a sealant. The results of this study clearly show that, by applying the invasive sealing technique, the choice of an adequate bur is important to obtain a caries-free fissure, with a minimal loss of tooth substance. Two types of burs were found to perform best, according to the amount of tooth substance removed. Moreover, from a clinical point of view they were also found to be the most efficient ones. A detailed review is given concerning the choice of the actual preventive restorations for use in pedodontics.
从牙科文献中可以清楚地看出，窝沟封闭剂的临床应用在儿童牙科学中是必要的。非侵入性技术和侵入性技术之间的选择仍然存在争议。在这项扫描电子显微镜研究中，对不同类型的车针进行了比较，以便在应用封闭剂之前获得最佳的窝沟预备。这项研究的结果清楚地表明，通过应用侵入性封闭技术，选择合适的车针对于获得无龋窝沟、使牙体组织损失最小至关重要。根据去除的牙体组织量，发现两种类型的车针表现最佳。此外，从临床角度来看，它们也是最有效的。文中对儿童牙科学中实际预防性修复体的选择进行了详细综述。
