introduction: in recent dentin adhesive systems etching of enamel/dentin are achieved simultaneously. the objective was to evaluate the microleakage of composite restorations using single bond2 (5th generation), clearfil s3 bond and g bond (7th generation). methods: class v cavities were prepared on 45 extracted intact premolars with gingival margins at the cementoenamel junction and they were...
Shear bond strength of dentin bonding agents to coronal and radicular dentin Dr. M. Barakatin * - Dr. MR. Malekypour * - Dr. P. Farjampour ** *Assistant Professor of Operative Dentistry & Dental Materials Dept., Faculty of Dentistry, Azad University (Khorasgan). ** Dentist. Abstract Background and Aim: The purpose of this study was to compare the shear bond strength of three bonding agents know...
Background and Aims: As in fissure sealant therapy the tooth surface is mostly enamel, the use of an enamel bonding agent (hydrophobic bonding agent) may be more cost effective than that of newer generations of bonding (hydrophilic bonding agents). The aim of this study was to compare the retention and durability of fissure sealant therapy when applying an enamel bonding agent, a dentin bondi...
background: marginal seal has a principal role in durability and clinical success offissure sealants. the aim of this study was to compare the microleakage of two materials used as pit and fissure sealant with different methods of application. methods: the 55 extracted premolars were assigned randomly to one ofthe following five groups: group 1: acid-etching (ultra-etch) + fissure sealant (conv...

An evaluation of the quality of the apical seal using a dentin bonding agent as a sealer with the single cone gutta percha obturation technique Dr. S. Moradi * - Dr. H. Gorjestani ** * Assistant Professor of Endodontics Dept., Faculty of Dentistry, Mashhad University of Medical Sciences. ** Assistant Professor of Endodontics Dept., Faculty of Dentistry, Kerman University of Medical Sciences. Ab...
Introduction: Contamination of etched enamel to saliva before placement of sealant prevents the appropriate bonding and results in microleakage. Using bondings is effective for decreasing the microleakage. This experimental study aimed to evaluate the effect of bonding agent on microleakage of a fissure sealant before or after contamination to saliva. Methods: In this experimental study 40 sou...
An evaluation on the effects of 37% phosphoric acid and self – etching primer on shear bond strength of enamel Dr. A. Davari* - Dr. H. Hajizadeh* - Dr. H. Sharifikhatoonabadi** *- Assistant Professor of Operative Dentistry Dept. - Faculty of Dentistry - Yazd University of Medical Sciences. **- Dentist. Background and Aim: The goal of this study was to evaluate the effects of 37% phosphoric acid...
background: bonding of molar tubes is becoming more popular in orthodontics. occasionally, these bonding are done on posterior porcelain crowns or bridges. the purpose of this study was to evaluate the shear bond strength of buccal tubes on feldspathic porcelain crowns with two different methods. materials and methods: forty porcelain right molar crowns were fabricated for this study. the crown...
Comparison of microleakage in different methods of restoration in posterior Clv cavities - Dr. N. Mohammadi* Dr. R. Khezrian** *- Assistant professor of Operative Dentistry Dept. Faculty of Dentistry Tabriz University of Medical Sciences. ** - Dentist. Background and aim: Despite improvements in the properties of composites, glass ionomers and other tooth colored materials, a nu...
