objectives: this study aimed to compare the microleakage beneath metallic brackets following two different methods of enamel preparation and light curing. materials and methods: a total of 120 bovine deciduous lower incisors were randomly divided into four groups of 30 teeth. the preparations were as follows: group i: acid etching + transbond xt primer + direct illumination, group ii: acid etch...
self etching primers, due to ease of manipulation, have been extensively used in recent years. these self etching primers containing a relatively weak acid, may not provide an optimal bond strength. the purpose of the present in-vitro investigation was to evaluate the effects of 37% phosphoric acid application prior to applying self etching primers on composite bond strength. in this experiment...
background: the aim of this study was to evaluate the shear bond strength of an antimicrobial and fluoride-releasing self-etch primer (clearfil protect bond) and compare it with transbond plus self-etch primer and conventional acid etching and priming system. materials and methods: forty-eight extracted human premolars were divided randomly to three groups. in group 1, the teeth were bonded wit...
background and aims. nano-ionomer (ni) interacts with tooth structures superficially, and there is a concern about the enamel bonding ability of mild self-etch ketac primer. this study compared the effect of different adhesive procedures (self-etching and etch-and-rinse approach) on long-term marginal microleakage of nano-filled resin-modified glass-ionomer (ni) cervical restorations. materials...

INTRODUCTION The use of self-etch primers has increased steadily because of their time savings and greater simplicity; however, overall benefits and potential disadvantages and harms have not been assessed systematically. In this study, we reviewed randomized controlled trials to assess the risk of attachment failure, bonding time, and demineralization adjacent to attachments between 1-stage (s...

Comparison of Helioseal F microleakage with 37% phosphoric acid and self – etch primer (In - vitro) Dr. Z. Bahrololoomi* - Dr. M. Nyazmand** *- Assistant Professor of Pedodontics Dept. - Faculty of Dentistry – Shaheed Sadoughi Yazd University of Medical Sciences. **- Dentist. Background and Aim: Recently, the use of self – etch primers, due to their ease of manipulation, for fissure sealant the...
statement of problem: the bond strength between restorative material and tooth structure is so important for conduction of durable restoration. considering the recent attention to low shrinkage composite resins, evaluation of micro tensile bond strength of these materials would be valuable. objectives: to compare the microtensile bond strength of silorane composite resin (filtek p90) with the c...
