本体外研究旨在比较新型化学机械去龋剂Carisolv（MediTeam AB，Sävedalen，Sweden）与传统慢速旋转器械（牙钻）的疗效。选取14颗离体的无釉质覆盖的深龋磨牙作为研究对象。其激光荧光值超过30（DIAGNOdent; KaVo，比伯拉赫，德国）。通过龋损中心对牙齿进行切片后，用传统钻孔（钻）去除一半;用Carisolv凝胶去除另一半。继续去除龋坏牙本质，直到通过视觉和触觉标准认为病变无龋为止。还记录了每种去龋技术的准备时间。将每颗牙齿的两半固定在10%的缓冲甲醛中1周。然后将它们脱钙、脱水并包埋在石蜡块中用于组织学研究。取5 μ m厚的连续切片后，将切片固定在载玻片上，脱蜡，脱水并用甲苯胺蓝染色，在光学显微镜下观察。检查每个切片是否存在细菌。14颗常规预备牙中有13颗（93%）龋蚀完全清除，而化学机械预备牙中有5颗（36%）龋蚀完全清除（P < 0.05）。Carisolv的平均（+/-SD）去龋时间为272 s（+/-53.3），钻孔为116 s（+/-49.4）。本研究的结果表明，传统旋转器械（牙钻）在去除龋组织方面比Carisolv更有效，而且所需时间更短。
The purpose of this in vitro study was to compare the efficacy of a new chemomechanical caries removal agent, Carisolv (MediTeam AB, Sävedalen, Sweden), with conventional slow-speed rotary instrument (bur). Fourteen extracted human molar teeth with deep dentine caries and no enamel coverage were selected for the study. Their laser fluorescence values were over 30 (DIAGNOdent; KaVo, Biberach, Germany). After the teeth were sectioned through the centre of the carious lesion, one half was removed with conventional drilling (bur); the other half was removed with Carisolv gel. Removal of carious dentine was continued until the lesion was deemed caries-free by visual and tactile criteria. The preparation time for each caries removal technique was also noted. The two halves of each tooth were fixed in 10% buffered-formaldehyde for 1 week. They were then decalcified, dehydrated and embedded in paraffin blocks for histological studies. After taking serial sections of 5 microm thickness, sections were mounted on glass slides, deparaffinized, dehydrated and stained with toluidine blue for observation under a light microscope. Each section was examined for the presence of bacteria. Complete removal of caries was achieved in 13 (93%) of 14 conventionally prepared teeth, and 5 (36%) of 14 chemomechanically prepared teeth (P < 0.05). Mean (+/-SD) time for caries removal was 272 s (+/-53.3) with Carisolv, and 116 s (+/-49.4) with drilling. The results of this study suggest that conventional rotary instrument (bur) was more effective than Carisolv in removal of carious tissue and also takes shorter time.
