This study was aimed to verify the debridement potential of the Caridex system against radicular cervical caries. 14 freshly extracted teeth with cervical caries were split and the fragments were freed from the dentinal caries using three methods: root planning (with a white stone), conventional excavation with a bur (tungsten) and the Caridex system. The results show that the Caridex system can partially dissolve the decayed dentin but leaves behind smeared surfaces as well as part of dentin infiltrated by bacteria. The root planning treatment smears the dentinal surface and thus blocks the tubules which also appeared to be infiltrated with bacteria. The excavation method allowed for a complete elimination of the decayed dentinal tissue down to the hypermineralized zone.
本研究旨在验证Caridex系统对牙根颈部龋的清创潜力。将14颗新拔除的颈部龋患牙劈开，然后使用三种方法从牙本质龋中分离出碎片：根面平整（用白色石尖）、用车针（钨钢）进行传统挖除以及使用Caridex系统。结果表明，Caridex系统可以部分溶解龋坏的牙本质，但会留下玷污层表面以及部分被细菌侵入的牙本质。根面平整处理会涂抹牙本质表面，从而堵塞似乎也被细菌侵入的牙本质小管。挖除法能够完全清除龋坏的牙本质组织直至矿化过度区。
