No consensus exists regarding the need for a second clinical session to remove carious dentin that remains in the pulp wall after partial caries removal. The purpose of the present article was to review studies that evaluated the effect of partial caries removal as provisional or definitive treatment on the dentinal microflora, the pulp response, or the progression of carious lesions in primary teeth. The results showed that partial caries removal performed in 1 session is more advantageous than removal in stages over 2 visits. This treatment, in addition to permitting the inactivation of caries lesions and reducing cariogenic micro-organisms in dentin, reduces the risk of pulp exposure caused by cavity reopening and excavation of remnant carious dentin. The favorable outcomes of partial caries removal in a single session support the indication of this modality as a definitive alternative restorative treatment for the primary dentition.
对于在部分龋损去除后，是否需要第二次临床操作来去除牙髓壁上残留的龋坏牙本质，目前尚无共识。本文的目的是综述一些研究，这些研究评估了部分龋损去除作为临时或确定性治疗对乳牙牙本质微生物群落、牙髓反应或龋损进展的影响。结果表明，一次完成部分龋损去除比分两次就诊逐步去除更具优势。这种治疗方法除了能使龋损失活并减少牙本质中的致龋微生物外，还降低了因窝洞重新开放和残留龋坏牙本质的挖掘而导致牙髓暴露的风险。单次就诊进行部分龋损去除的良好效果支持将这种治疗方式作为乳牙确定性替代修复治疗的适应证。
