摘要
目的:本研究旨在研究经光活化釉处理或未经热循环处理的临时假体表面的血链球菌粘附性。方法每种树脂36份标本分为4组:热活化丙烯酸树脂组;化学活化丙烯酸树脂;双丙烯酸酯复合树脂(Protemp;3 m ESPE);和bis-GMA (Charisma);贺利氏Kulzer)。一半的标本进行了上釉,另一半进行了机械抛光。将标本随机分为有热循环和无热循环两组(N = 9),各2000个循环。表面能,粗糙度和微生物分析。结果在热循环前后,除双丙烯酸基团外,釉处理组的表面粗糙度均低于未处理组。除热循环前后的双丙烯酸基团外,釉料处理组的表面能值均较高。热循环后,除经釉处理的化学活化丙烯酸树脂组和未经釉处理的热活化丙烯酸树脂组外,细菌粘附力数值均下降。结论釉料的应用和热循环对细菌在聚合物表面的粘附无显著影响。
Influence of a light-activated glaze on the adhesion of Streptococcus sanguinis to the surface of polymers used in fabrication of interim prostheses
Aim
This study aimed to investigate the adhesion of Streptococcus sanguinis to the surface of interim prostheses that were treated or not treated with a light-activated glaze, and subjected or not subjected to a thermocycling procedure.
Methods
36 specimens of each resin were divided into 4 groups: heat-activated acrylic resin; chemically-activated acrylic resin; bis-acryl composite resin (Protemp; 3M ESPE); and bis-GMA (Charisma; Heraeus Kulzer). Half of the specimens underwent application of glaze and the other half underwent mechanical polishing. Specimens were randomly distributed into groups (N = 9) with and without thermocycling (2000 cycles). Surface energy, roughness and microbiological analyses were performed.
Results
Groups treated with glaze showed lower roughness when compared with the same groups without glaze treatment, before and after thermocycling, except for the bis-acryl groups after thermocycling. Surface energy values were higher in the groups treated with glaze, except the bis-acryl group before and after thermocycling. After thermocycling, the values of bacterial adhesion decreased numerically, with the exception of the chemically-activated acrylic resin group treated with glaze and the heat-activated acrylic resin group without glaze treatment.
Conclusion
The application of glaze and the thermocycling do not influence, in a statistically significant manner, the bacterial adhesion on polymer surfaces.
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.
