The change in the concepts of cavity preparation and the development of reliable adhesive materials lead to the development of alternative methods of caries removal. Chemo-mechanical caries removal (CMCR) involves the chemical softening of carious dentin, followed by its removal with gentle excavation.
The present study was conducted to evaluate clinically the efficiency of caries removal using a new chemo-mechanical agent (Papacarie) compared to the conventional drilling method including the need for local anesthesia, the need for drill, duration of the treatment and the pain reaction.
This study was split mouth design. The study was performed on thirty seven bilateral open carious lesions. They were divided into two equal groups according to method of caries removal. In Group I, caries was removed using the Papacarie system and in Group II, caries was removed with the conventional drill.
The results showed that the Papacarie was as efficient as the drill in caries removal from open carious lesions with no significant difference in the operating time. The new CMCR agent also reduced significantly the need for local anesthesia and the use of drill. In addition, Papacarie was also more comfortable than the traditional rotatory instruments.
It was concluded that Papacarie could be an effective caries removal method to treat children, particularly those who present with early childhood caries or management problems.
窝洞制备概念的改变以及可靠粘结材料的发展导致了龋病去除替代方法的发展。化学机械去龋（CMCR）包括龋坏牙本质的化学软化，随后通过轻柔挖除将其去除。
本研究旨在临床评估一种新型化学机械制剂（Papacarie）与传统钻牙方法相比在龋病去除方面的效果，包括局部麻醉的需求、钻牙的需求、治疗持续时间和疼痛反应。
本研究采用双侧对照设计。对37例双侧开放性龋损进行研究。根据龋病去除方法将它们分为两组，每组数量相等。第一组使用Papacarie系统去除龋坏组织，第二组使用传统钻去除龋坏组织。
结果表明，Papacarie在去除开放性龋损中的龋坏组织方面与钻牙效果相同，操作时间无显著差异。这种新型化学机械制剂还显著减少了局部麻醉的需求和钻牙的使用。此外，Papacarie比传统旋转器械更舒适。
得出结论，Papacarie可能是一种治疗儿童龋病的有效方法，特别是那些患有早期儿童龋病或治疗存在问题的儿童。
