密封剂材料通常用于牙科，以防止牙齿上形成空腔。它们防止细菌粘附到牙釉质上，从而阻止脱矿和龋齿的发展。在这项研究中，不同的密封剂材料之间的界面的临界区和牙齿加工的牙齿工作的结果进行了研究离体扫描源（SS）光学相干断层扫描（OCT）。光学检查和X射线检查没有发现任何缺陷，而SS-OCT证明能够准确评估每种类型缺陷的位置、性质和尺寸。具体而言，针对窝沟封闭剂的结构的不同失效，包括气泡、内部裂纹、封闭剂材料的结构缺陷和釉质的结构缺陷，以及未覆盖的封闭剂材料和釉质/封闭剂界面（牙科封闭剂的边缘完整性和边缘适应性）。因此，为牙科医生完成了对可能出现在该牙科界面中的缺陷类型的调查。
Sealant materials are typically employed in dentistry in order to prevent the development of cavities on the teeth. They prevent bacterial adhesion to enamel, thus arresting the development of demineralization and of caries. In this study, the critical zone of the interface between different sealant materials and the results of the dental work for the teeth processed were investigated ex vivo using swept source (SS) optical coherence tomography (OCT). Optical inspection and X-ray investigation revealed no defects, while SS-OCT proved capable to asses exactly the position, the nature, and the dimensions of each type of these defects. Specifically, different failures were targeted into the structure of pit and fissure sealants, including bubbles, internal cracks, structural defects of sealant material, and structural defects of enamel, with uncovered sealant material and enamel/sealant interface (marginal integrity and marginal adaptation of dental sealant). The investigation of the possible types of defects that may appear into this dental interface was thus accomplished - for the dental practitioner.
