Introduction: In orthodontic treatment, it is essential to establish a satisfactory bond between enamel and bracket. After the self-etch primers (SEPs) were introduced for the facilitation of bracket bonding in comparison to the conventional etch-and-bond system, multiple studies have been carried out on their shear bond strengths which have yielded different results. This study was aimed at co...
Background and Aim: By application of casein phosphopeptide amorphous calcium phosphate (CPP-ACP) as a remineralizing agent, it may be feasible to only remove the carious dentin and better preserve the tooth structure. This study aimed to assess the shear bond strength of composite to primary enamel treated with CPP-ACP using total-etch and self-etch bonding systems. Materials and Methods: T...
A good adhesive is an important factor to consider in orthodontic bonding. Frequent bracket failure prolongs treatment duration and causes inconvenience to patient and operator. This study aimed to compare the effectiveness of two bonding agents, i.e. the self etching primer (SEP) and the conventional etch and bond (CEB) by monitoring the incidence, time and sites of bracket failure. Eighty ort...
Background and aims. The aim of this study was to evaluate the effect of dilution and curing methods of an etch-and-rinse adhesive and a self-etching primer from the same manufacturer at early exposure time on cytotoxicity of primary human gingival fibroblasts. Materials and methods. Primary human gingival fibroblasts were exposed to different dilutions of Adper Single Bond (ASB) and Adper Prom...
objective: microleakage has always been a problem in restorative dentistry. to decrease microleakage, modern bonding systems, different application methods and sandwich technique have been recommended. the purpose of this study was to assess the microleakage in class v cavities restored with open sandwich technique using self-etch and total-etch bonding systems. methods: in this in vitro stud...
Current dental adhesive technology involves either an etch-and-rinse or self-etching approach.8 Evidence of clinical durability exists for both approaches, albeit depending on the specific brand.4,5 Today, enamel still requires phosphoric-acid etching and thus an etch-andrinse approach to obtain a durable bond. The adhesiveenamel bond seals the cavity and even protects the more vulnerable bond ...
background and aims. the aim was to evaluate the effect of casein phosphopeptide–amorphous calcium phosphate (cpp-acp) on microtensile bond strength (µtbs) to carious affected dentin (cad) using etch-and-rinse and self-etch adhesive systems. materials and methods. the occlusal surface of 32 human molars with moderate occlusal caries was removed. infected dentin was removed until reaching cad an...
Introduction: Nowadays, the main focus of dental studies is on adhesive dental materials; since clinical long-term success of bonded restorations depended more on marginal microleakage minimization. So, the aim of this study was Evaluation of Diode laser irradiation effect on microleakage in class V composite restoration before and after adhesive application. Materials and methods: In this in v...
OBJECTIVES The aim of this in vitro study is to determine (1) shear bond strength (SBS) of brackets bonded with self-etch and total-etch adhesive after ozone treatment (2) bond failure interface using a modified Adhesive Remnant Index (ARI). METHODS 52 premolars were randomly assigned into four groups (n=13) and received the following treatments: Group 1: 30 s Ozone (Biozonix, Ozonytron, Veho...
Background and Aim: Data regarding the efficacy of universal adhesives are limited. This study aimed to assess the durability of a universal adhesive bond to superficial dentin using etch and rinse and self-etch modes. Materials and Methods: In this in vitro, experimental study, 32 sound molars were randomly divided into two groups of Scotchbond Universal adhesive with two-step etch and rins...
