Shear bond strengths of calcium silicate-based sealer to dentin and calcium silicate-impregnated gutta-percha
Aim
To compare the shear bond strengths of a calcium silicate-based root canal sealer (CSS), to dentin or calcium silicate-impregnated gutta-percha (CSGP), with the shear bond strengths of an epoxy resin-based sealer.
Methods
For sealer/dentin testing, 40 hemisectioned roots were divided into 2 groups. Coronal root dentin discs were bonded with CSS or epoxy resin-based sealer. For sealer/core material testing, CSGP and conventional gutta-percha discs were bonded with a matching sealer (N = 20 per group). The shear bond strengths were tested using a universal testing machine. The failed modes were analyzed using stereomicroscopy and scanning electron microscopy.
Results
The CSS sealer had significantly higher shear bond strength to dentin than did epoxy resin-based sealer (P < .01). However, shear bond strengths of the 2 sealers to core materials did not significantly differ (P = .74). The remnants of the CSS sealer adhering to dentin or calcium silicate gutta-percha disc were observed.
Conclusions
The CSS sealer had better adhesion to dentin than did epoxy resin-based sealer. However, the bond of the CSS sealer to impregnated gutta-percha was not superior to the epoxy resin-based sealer bonded to conventional gutta-percha.
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.
