摘要

目的研究四氟化钛(TiF 4)溶液对酸蚀症牙本质粘接强度的影响。

方法选取24颗新鲜拔除的人第三磨牙,获取冠部近髓腔的牙本质,随机分为6组,每组4颗牙,其中4组通过酸蚀和机械力方法建立人工酸蚀症牙本质模型,另外2组为健康牙本质。随机选取1组人工酸蚀症牙本质和1组健康牙本质,使用扫描电镜和显微硬度仪测定其表面形貌与表面硬度,评价人工酸蚀症牙本质的建模效果。另外3组人工酸蚀症牙本质和1组健康牙本质用于粘接测试,按不同处理分为4组:4.0% TiF 4处理酸蚀症牙本质组(4.0% TiF 4-ED组)、2.5% TiF 4处理酸蚀症牙本质组(2.5% TiF 4-ED组)、无处理酸蚀症牙本质组(ED组)及健康牙本质组(SD组)。使用SE Bond自酸蚀粘接系统进行粘接,AP-X复合树脂分层充填,测定即刻微拉伸粘接强度并观察断裂模式。

结果人工酸蚀症牙本质和健康牙本质的显微硬度值分别为(56.92±5.27)HV和(60.19±4.52)HV,组间比较差异有统计学意义( P<0.05)。扫描电镜结果证实,人工酸蚀症牙本质与自然酸蚀症牙本质的微观形貌特征相符。4.0% TiF 4-ED组、2.5% TiF 4-ED组、ED组和SD组的微拉伸粘接强度分别为(28.94±8.04)MPa、(46.08±8.19)MPa、(20.39±7.46)MPa和(45.16±7.86)MPa。2.5% TiF 4-ED组和SD组的微拉伸粘接强度比较,差异无统计学意义( P=0.529),二者均高于4.0% TiF 4-ED组和ED组(均 P<0.05)。4组断裂模式分布比较,差异有统计学意义( χ 2=54.91, P<0.001)。2.5% TiF 4-ED组以内聚牙本质断裂为主,提示其粘接强度可能高于微拉伸测试均值。

结论酸蚀症牙本质粘接强度低于健康牙本质,2.5% TiF 4溶液可显著提高酸蚀症牙本质的粘接强度。

ABSTRACT

ObjectiveTo investigate the effect of titanium tetrafluoride (TiF 4) solution on bonding strength of acid-etched dentin.

MethodsTooth crown dentin proximal to the pulp cavity was obtained from 24 freshly-extracted human third molars and randomly divided into 6 groups ( n=4 each) . Among them, 4 groups were modeled for artificial acid-etched dentin by means of acid-etching and mechanical friction. The other 2 groups were used as sound dentin controls. One each of the artificial acid-etched dentin groups and sound dentin control groups were randomly selected and studied under scanning electron microscope and microhardness tester to measure the surface morphology and hardness, and to evaluate the effectivity of the modeling for artificial acid-etched dentin. The other 3 groups of artificial acid-etched dentin and remaining group of healthy dentin were used for bonding test, re-assigned into 4 groups according to different treatments: etched dentin treated with 4.0% TiF 4 (4.0% TiF 4-ED group) , etched dentin treated with 2.5% TiF 4 (2.5% TiF 4-ED group) , untreated etched dentin (ED group) and sound dentin control (SD group) . All dentin samples were then bonded with a self-etching system (SE bond) , layered by AP-X composite resin with light-curing. Microtensile bonding strength (μTBS) test was used to measure the immediate bonding strength and to determine the fracture pattern.

ResultsThe microhardness values of artificial acid-eched dentin and sound dentin were (56.92±5.27) HV and (60.19±4.52) HV, respectively, with significant difference between groups ( P<0.05) . Scanning electron microscopy confirmed that the artificial acid-etched dentin presented microscopic morphological characteristics consistent to natural acid etching. The μTBS of 4.0% TiF 4-ED group, 2.5% TiF 4-ED group, ED group and SD group were (28.94±8.04) MPa, (46.08±8.19) MPa, (20.39±7.46) MPa and (45.16±7.86) MPa, respectively. The μTBS did not differ significantly between the 2.5% TiF 4-ED group and the SD group ( P=0.529) , and both were higher than those in the 4.0% TiF 4-ED group and the ED group (all P<0.05) . The fracture patterns differed significantly among the 4 groups ( χ 2=54.91, P<0.001) . In the 2.5% TiF 4-ED group, cohesive dentin fracture was the main cause, suggesting that the bonding strength may be higher than the mean measurements from the micro-tensile test.

ConclusionThe bonding strength of acid-etched dentin is lower compared with sound dentin. 2.5% TiF 4 solution can significantly improve the bonding strength of acid-etched dentin.

牙酸蚀症是指牙齿受到非细菌性酸的侵蚀,酸性物质对牙齿硬组织中的羟基磷灰石酸蚀脱矿,导致牙齿表面硬组织的进行性丧失 [ 1 ]。而酸蚀导致的牙齿表面硬组织脱矿软化,是牙齿磨耗的重要始动及促进因素 [ 2 ]。牙酸蚀症可以导致牙齿重度磨耗的发生 [ 3 ],给患者带来诸如牙齿敏感不适、疼痛等症状,并引起咀嚼效能下降。造成牙齿侵蚀的酸可分为内源性酸及外源性酸,随着软饮料特别是碳酸饮料消费量日趋升高,牙酸蚀症的发病率正在快速提高,全球范围内青少年及成人牙酸蚀症的发病率已超过30% [ 4 , 5 , 6 ]
近年来随着微创理念流行且技术日益发展,树脂粘接已经成为牙酸蚀症修复治疗的核心要素 [ 7 , 8 ]。当酸蚀仅累及牙釉质时,自酸蚀树脂粘接系统的粘接强度下降 [ 9 ],而全酸蚀树脂粘接系统尚能提供临床可接受的粘接强度 [ 10 ];但当酸蚀症进一步侵犯牙本质层而形成酸蚀症牙本质时,目前广泛使用的各类粘接系统及其相应产品则表现为较健康牙本质降低的粘接强度 [ 11 , 12 ]。当前应用广泛的通用型自酸蚀树脂粘接系统对酸蚀症牙本质的即刻粘接强度仅约为健康牙本质的一半,而当牙本质酸蚀合并机械力时粘接强度相比单纯酸蚀则有进一步下降的趋势 [ 12 ],因此对酸蚀症牙本质粘接应做进一步研究。
四氟化钛(tetroflouride,TiF 4)属于金属氟化物的一种,TiF 4水溶液可与牙本质表面暴露的胶原纤维结合并固定,提高牙本质表面的硬度及弹性模量 [ 13 ];它还可以在牙本质表面形成一层致密的二氧化钛氧化层,具有抗微渗漏、抗酸等作用,可用于酸蚀症的预防 [ 14 ]。Torres等 [ 15 ]及Basting等 [ 16 ]研究发现TiF 4可被添加至两步法自酸蚀系统的预处理剂中,并可稳定地存在且不影响对健康牙本质的粘接效果;Tranquilin等 [ 17 ]研究发现,在应用全酸蚀系统行健康牙本质粘接时,磷酸酸蚀后再涂布TiF 4溶液,可提高牙本质粘接强度。上述研究提示,TiF 4有望提高酸蚀症牙本质的粘接强度。
研究发现,0.1%~4%的TiF 4均可增强牙齿抗酸及抗龋能力 [ 18 , 19 , 20 ],且在这一范围内浓度越高抗酸效果越好。在牙本质粘接领域,2.5%和4.0%(w/v)是两个常见的浓度 [ 12 , 15 , 16 , 17 ],故本研究尝试采用2.5%及4.0%浓度的TiF 4溶液处理酸蚀症牙本质,观察其对酸蚀症牙本质粘接的影响,报告如下。
