Antiseptics and microcosm biofilm formation on titanium surfaces

Abstract Oral rehabilitation with osseointegrated implants is a way to restore esthetics and masticatory function in edentulous patients, but bacterial colonization around the implants may lead to mucositis or peri-implantitis and consequent implant loss. Peri-implantitis is the main complication of oral rehabilitation with dental implants and, therefore, it is necessary to take into account the potential effects of antiseptics such as chlorhexidine (CHX), chloramine T (CHT), triclosan (TRI), and essential oils (EO) on bacterial adhesion and on biofilm formation. To assess the action of these substances, we used the microcosm technique, in which the oral environment and periodontal conditions are simulated in vitro on titanium discs with different surface treatments (smooth surface - SS, acid-etched smooth surface - AESS, sand-blasted surface - SBS, and sand-blasted and acid-etched surface - SBAES). Roughness measurements yielded the following results: SS: 0.47 µm, AESS: 0.43 µm, SB: 0.79 µm, and SBAES: 0.72 µm. There was statistical difference only between SBS and AESS. There was no statistical difference among antiseptic treatments. However, EO and CHT showed lower bacterial counts compared with the saline solution treatment (control group). Thus, the current gold standard (CHX) did not outperform CHT and EO, which were efficient in reducing the biofilm biomass compared with saline solution.

Doença periodontal e diabete melito tipo 2 / Periodontal disease and diabete melito type 2

Introdução: a doença periodontal é considerada a sexta complicação clássica do diabete melito. Estudos recentes relatam que o diabete melito e a doença periodontal apresentam uma associação bidirecional, na qual o diabete favorece o desenvolvimento da doença periodontal e esta, quando não tratada, dificulta o controle metabólico do diabete. As periodontites relacionadas a doenças sistêmicas são causadas pela placa bacteriana e também exacerbadas pela condição oral. Objetivo: realizar uma revisão de literatura em relação à influência da doença periodontal no fator sistêmico do paciente diabético, e por sua vez, a influência do diabete no desenvolvimento e progressão da doença periodontal. Conclusão: o diabete melito é um fator de importância na incidência e prevalência da doença periodontal, assim como a doença periodontal pode ter influência sobre o controle metabólico do diabete. O tratamento periodontal parece contribuir para a melhoria do controle glicêmico de indivíduos diabéticos e com doença periodontal.

Introduction: periodontal disease is considered the sixth classic complication of the diabetes melito. Recent studies tell that the diabetes melito and the periodontal disease represent a bidirectional association, in which the diabetes favors the development of the periodontal disease and this, when no treated, it hinders the metabolic control of the diabetes. The periodontites related to systemic diseases are caused by bacterial plate and also exacerbated by the oral condition. Objective: accomplish a literature revision in relation to the influence of the periodontal disease in the diabetic patient’s systemic factor, and for its time, the influence of the diabetes in the development and progression of the periodontal disease. Conclusion: the diabetes melito is a factor of importance in the incidence and prevalence of periodontal disease, as well as the periodontal disease it can have influence on the metabolic control of the diabetes. The periodontal treatment seems to contribute for the improvement of the glycemic control of diabetic individuals and with periodontal disease.
