Abstract

The study evaluated the effect of sodium hypochlorite (NaOCl) treatment on fluorotic enamel bonding of four adhesive systems. They were Single Bond 2 (SB2), Prime&Bond NT (PBN), Clearfil SE Bond (CSB), and Single Bond Universal (SBU). One hundred eighteen extracted moderate fluorotic molars were divided into eight groups according to NaOCl pretreatment and four adhesive systems. The microshear bond strength (μSBS), etching pattern, and penetration depth (PD) were observed. The statistical method was two-way ANOVA and least significant difference (LSD) test (α=0.05). The application of NaOCl significantly increased the μSBS of PBN and SBU (p<0.05). The enamel-etching pattern of CSB and SBU was deeper under SEM. A noticeable increase of PD was in SB2 and SBU after the application of NaOCl (p<0.05). Pretreatment of 5.25% NaOCl for the 60 s can increase μSBS of PBN and SBU, PD of SB2 and SBU, and improve enamel-etching pattern of CSB and SBU to fluorotic enamel.

摘要

该研究评估了次氯酸钠（NaOCl）处理对四种粘结系统与氟斑牙釉质粘结效果的影响。这四种粘结系统分别是单键二代（SB2）、全优粘结剂（PBN）、可乐丽SE粘结剂（CSB）和单键通用型粘结剂（SBU）。118颗拔除的中度氟斑磨牙根据NaOCl预处理情况和四种粘结系统分为八组。观察微拉伸粘结强度（μSBS）、酸蚀模式和渗透深度（PD）。统计方法为双向方差分析和最小显著差（LSD）检验（α = 0.05）。NaOCl的应用显著提高了PBN和SBU的μSBS（p < 0.05）。在扫描电子显微镜下，CSB和SBU的釉质酸蚀模式更深。应用NaOCl后，SB2和SBU的PD显著增加（p < 0.05）。用5.25%的NaOCl预处理60秒可提高PBN和SBU的μSBS、SB2和SBU的PD，并改善CSB和SBU与氟斑牙釉质的釉质酸蚀模式。
