Interfacial fracture toughness of self-adhesive and conventional flowable composites to dentin using different dentin pretreatments
Aim
The aim of the present study was to investigate the effect of different dentin pretreatments on the interfacial fracture toughness of a self-adhesive flowable composite to dentin compared with that of a conventional flowable composite.
Methods
Caries-free human molars were sectioned to expose the underlying dentin and were randomly divided into seven groups (N = 12) of dentin pretreatments bonded to a self-adhesive flowable composite (Vetise Flow, VF) or a conventional flowable composite (Clearfil Magesty Flow, CM). For VF; Control group (group C-VF), there was no pretreatment, self-etching primer (SP), oxalate dentin desensitizer (OX), and chlorhexidine gluconate (CH) were used. For CM; SP (group SP-CM), OX followed by SP (OX-CM), and CH followed by SP (CH-CM) were used. The interfacial fracture toughness was measured using a universal testing machine. Data were analyzed by Kruskal-Wallis test and analysis of variance.
Results
For VF, the fracture toughness of SP-VF was significantly higher than that of other groups. For CM, a significantly higher fracture toughness for SP-CM than that of OX-CM was found. For all dentin pretreatments, the fracture toughness values were significantly higher for CM compared with the VF.
Conclusions
The self-adhesive flowable composite had reduced bonding efficacy to dentin compared with that of the conventional flowable composite, regardless of the type of dentin pretreatment.
期刊介绍：
Journal of Investigative and Clinical Dentistry (JICD) aims to publish quality, peer reviewed original research and topical reviews on all aspects of investigative and clinical dentistry and craniofacial research, including molecular studies related to oral health and disease. Although international in outlook, the Editor especially encourages papers from the Asia Pacific. The journal also aims to provide clinicians, scientists and students of dentistry with a knowledge transfer platform for rapid publication of reports through an international journal, which will be available free online until 2012. Its scope, therefore, is broad, inclusive and international, but with a particular focus on Asia Pacific. The Editor welcomes manuscripts in the following key thematic areas in oral and maxillofacial sciences: Community Dentistry and Oral Epidemiology, Conservative Dentistry, Dental Biomaterials, Dental Pedagogy, Endodontics and Traumatology, Implant Dentistry, Oral Biosciences, Oral and Maxillofacial Surgery, Oral Medicine, Oral Pathology and Oral Microbiology, Orthodontics, Oral Radiology, Oral Rehabilitation, Paedodontics, Periodontology and Periodontal Medicine.
