This study aimed to compare the effect of proanthocyanidin-rich grape seed extract (Pa-rich GSE) in two different concentrations on the bond strength to dentin tissue for four different cement groups (resin cement (P), resin modified glass ionomer cement (K), calcium aluminate glass ionomer cement (C), glass ionomer cement (G)). One hundred and eighty dentin surfaces of the extracted molar teeth placed on acrylic cylinders were divided into 12 groups randomly ( = 15). Each cement group was further divided into control (CP, CC, CK, CG), 6.5% Pa-rich GSE (P6.5, C6.5, K6.5, G6.5) and 12.5% Pa-rich GSE (P12.5, C12.5, K12.5, G12.5) subgroups. In accordance with the manufacturer's recommendations the cements were applied. After shear bond tests, surfaces were examined under a stereomicroscope. Median shear bond strength (in MPa) of CP, CK, CC, CG groups were 14.13, 7.05, 4.87, 3.86; for the P6.5, G6.5, C6.5, K6.5 groups they were 13.98, 13.42, 6.21, 3.27; and for the P12.5, C12.5, K12.5, G12.5 groups they were 15.08, 5.40, 3.10, 0.00, respectively. CK and K6.5 groups showed a significant difference from the K12.5 group ( < 0.05). Also, CG, G6.5 and G12.5 groups were found statistically different from each other ( < 0.05). Applied to the dentin surface, 6.5% Pa-rich GSE enhanced the bond strength of glass ionomer cements.
本研究旨在比较两种不同浓度的富含原花青素的葡萄籽提取物（富含原花青素的GSE）对四种不同粘结剂组（树脂粘结剂（P）、树脂改性玻璃离子粘结剂（K）、铝酸钙玻璃离子粘结剂（C）、玻璃离子粘结剂（G））与牙本质组织粘结强度的影响。将放置在丙烯酸圆柱体上的180颗拔除磨牙的牙本质表面随机分为12组（每组n = 15）。每个粘结剂组进一步分为对照组（CP、CC、CK、CG）、6.5%富含原花青素的GSE组（P6.5、C6.5、K6.5、G6.5）和12.5%富含原花青素的GSE组（P12.5、C12.5、K12.5、G12.5）亚组。按照制造商的建议应用粘结剂。在进行剪切粘结试验后，在体视显微镜下检查表面。CP、CK、CC、CG组的中位剪切粘结强度（单位：MPa）分别为14.13、7.05、4.87、3.86；P6.5、G6.5、C6.5、K6.5组分别为13.98、13.42、6.21、3.27；P12.5、C12.5、K12.5、G12.5组分别为15.08、5.40、3.10、0.00。CK组和K6.5组与K12.5组相比有显著差异（P < 0.05）。此外，CG组、G6.5组和G12.5组在统计学上彼此不同（P < 0.05）。应用于牙本质表面时，6.5%富含原花青素的GSE可提高玻璃离子粘结剂的粘结强度。
