Objectives: To evaluate the influence of the surface treatment and adhesive system on the shear bond strength and the failure mode of orthodontic brackets bonded to polymethylmethacrylate surfaces. Methods: Ninety metal brackets (n=15) were bonded to aged discs of polymethylmethacrylate SR Ivocron subjected to three ...

Objective: To evaluate the influence of light exposure time on the adhesive strength and thefailure mode of orthodontic brackets bonded to human enamel. Methods: 100 metal brackets were bonded with Transbond XT to the enamel bucal surface of human premolars. The sample was randomly divided into 5 experimental groups ...

Objectives: To evaluate the influence of dental fluorosis and etching time on the shear bond strengths (SBSs) of orthodontic brackets to human enamel. Methods: A total of 48 human maxillary central incisors, extracted for periodontal reasons were used. The sample was divided into three experimental groups (n = 16): gro...

Objetivos: Estudar a influência do tipo de bracket estético sobre a resistência ficcional de arcos de aço inoxidável; determinar o efeito da alteração na angulação de segunda ordem entre bracket e fio ortodôntico sobre a fricção produzid...

Objectives: To compare the effects of application mode of one self-etching adhesive on theshear bond strength of metallic orthodontic brackets. Methods: Seventy-five healthy bovine incisors were divided into 5 groups (n = 15). The self-etching primer (Transbond Plus, 3M Unitek) was applied on the enamel actively and p...
