A study of the pulpal biocompatibility of the Caridex system was carried out on human premolars to be extracted bilaterally for orthodontic reasons, in 3 volunteers aged 10 to 13 years. A class V cavity was prepared bilaterally on the 2 premolars to be extracted: one of the cavities was washed with Caridex. The other was used as a control. The extractions were made immediately, 4 and 7 weeks after these operative procedures. Histological examinations showed that the Caridex system was biocompatible for the human dental pulp. A comparative study of carious cavities was conducted using light microscopy, Gram stain and transmission electron microscopy on the quality of the cleaning obtained after conventional cavity preparation and use of the Caridex system. After Caridex treatment, the dentinal surface was free of demineralized zones and no smear layer was present. The occasional presence of bacteria was noticed after conventional use of a bur as well as after Caridex. More limited clinical indications of the Caridex system are proposed.
对3名年龄在10至13岁的志愿者进行了一项研究，该研究针对因正畸原因需双侧拔除的人类前磨牙，评估了Caridex系统的牙髓生物相容性。在拟拔除的2颗前磨牙双侧制备V类洞：其中一个洞用Caridex冲洗。另一个作为对照。在这些手术操作后立即、4周和7周进行拔牙。组织学检查表明，Caridex系统对人类牙髓具有生物相容性。使用光学显微镜、革兰氏染色和透射电子显微镜对传统洞制备和使用Caridex系统后获得的清洁质量进行了龋洞的比较研究。经Caridex处理后，牙本质表面无脱矿区域，也不存在玷污层。在传统使用车针后以及使用Caridex后，偶尔会发现细菌。提出了Caridex系统更有限的临床适应症。
