Abstract

Purpose: To evaluate the effect of different concentrations of ethylene-diamine-tetra acetic acid (EDTA) on bond strength (BS) and nanoleakage (NL) of fiber posts bonded into root canals.

Materials and methods: Seventy-two single roots were endodontically treated and divided into six groups (n = 12), according to the combination of the following factors: surface treatment (no irrigation [control], 17% EDTA, or 24% EDTA), and composite cement applied with an adhesive used in a self-etch mode (Single Bond Universal/RelyX Ultimate [SB], 3M Oral Care; Ambar Universal/Allcem [AM], FGM). After fiber post cementation, six 1-mm-thick disks were obtained for each root. Push-out bond strength (BS) was evaluated using 8 specimens per group, and the other 4 specimens were used to examine nanoleakage (NL). Data from BS and NL of each adhesive were evaluated by two-way ANOVA (surface treatment vs root region) and Tukey's test (α = 0.05).

Results: The application of 17% and 24% EDTA did not influence the bond strengths of either adhesive. In general, the application of 17% and 24% EDTA increased NL values for both adhesives.

Conclusion: Pre-treatment with different concentrations of EDTA was not able to improve the adhesion of fiber posts into root canals with universal adhesives..

EDTA灌洗液对纤维桩into根管与通用粘接剂粘接的影响。

目的:评价不同浓度的乙二胺四乙酸(EDTA)对纤维桩粘结into根canals的粘结强度(BS)和纳米渗漏(NL)的影响。材料和方法:对72根单根进行根管治疗，根据以下因素的组合分为6组(n = 12):表面处理(无冲洗[对照]，17% EDTA，或24% EDTA)，复合胶合剂应用于自蚀刻模式的粘合剂(single Bond Universal/RelyX Ultimate [SB]， 3M Oral Care;Ambar Universal/Allcem [AM] [， FGM]]。纤维桩胶结后，每个根获得6个1 mm厚的盘。每组取8个试件进行推出粘结强度(BS)评估，其余4个试件进行纳米渗漏(NL)检测。采用双因素方差分析(表面处理vs根区)和Tukey检验(α = 0.05)对各胶粘剂的BS和NL数据进行评估。结果:应用17%和24% EDTA对两种胶粘剂的粘接强度of均无影响。总的来说，17%和24%的EDTA的应用增加了两种胶粘剂的NL值。结论:不同浓度的EDTA预处理均不能改善纤维桩into root canals与通用adhesives.的粘连性。

期刊介绍： New materials and applications for adhesion are profoundly changing the way dentistry is delivered. Bonding techniques, which have long been restricted to the tooth hard tissues, enamel, and dentin, have obvious applications in operative and preventive dentistry, as well as in esthetic and pediatric dentistry, prosthodontics, and orthodontics. The current development of adhesive techniques for soft tissues and slow-releasing agents will expand applications to include periodontics and oral surgery. Scientifically sound, peer-reviewed articles explore the latest innovations in these emerging fields.
