手术干预后炎症活动的影响可损伤牙髓组织;在严重的情况下，它可导致牙髓并发症。在这篇文章中，作者报告了洞准备和修复事件的影响，以及它们如何相互作用，以减少或增加202个修复的V类洞中牙髓炎症活动的严重程度。虽然在没有细菌的情况下观察到一些炎症活动，但当腔体感染时，牙髓炎症活动的严重程度增加。氧化锌丁香油酚和树脂改性玻璃离子水门汀可防止洞体修复中的细菌微渗漏，这些材料未观察到严重的炎症活动。在用牙釉质粘结树脂和粘合剂粘结复合材料修复的洞中观察到细菌，并且与严重的炎症活动等级相关。洞内残留牙本质厚度影响炎症活动程度。在没有感染的情况下，术后20周后炎症活动度降低。在存在感染的情况下，牙髓炎症的等级保持稳定，直到至少30周过去。
The effects of inflammatory activity following surgical intervention can injure pulp tissues; in severe cases it can lead to pulpal complications. With this article, the authors report on the effects of cavity preparation and restoration events and how they can interact together to reduce or increase the severity of pulpal inflammatory activity in 202 restored Class V cavities. Although some inflammatory activity was observed in the absence of bacteria, the severity of pulpal inflammatory activity was increased when cavity restorations became infected. Zinc oxide eugenol and resin-modified glass ionomer cement prevented bacterial microleakage in cavity restorations, with no severe inflammatory activity observed with these materials. Bacteria were observed in cavities restored with enamel bonding resin and adhesive bonded composites and were associated with severe grades of inflammatory activity. The cavity remaining dentin thickness influenced the grade of inflammatory activity. In the absence of infection, the grade of inflammatory activity decreased after 20 weeks post-operatively. In the presence of infection, the grade of pulpal inflammation remained stable until a minimum of 30 weeks had elapsed.
