Avaliação in vitro da ação de substâncias químicas auxiliares, clorexidina e medicações intracanais sobre C. albicans, E. faecalis, E. coli e sua endotoxina em canais radiculares: [recurso eletrônico]

The purpose of this study was to evaluate the antimicrobial activity of chlorhexidine gel 2% as auxiliary chemical substance on the biomechanical preparation (BMP) and medication intracanal (ICM) on C. albicans, E. faecalis, E. coli and their endotoxin in root canals. We used 48 single-rooted human teeth divided into four groups according to dressing ICM: 1) Ca(OH)2 + pyrogen-free saline solution; 2) 2% chlorhexidine gel (CLX); 3) Ca(OH)2 + CLX, and; 4) pyrogen-free saline solution (control group). Were collected the contents of root canals to confirm the presence of microorganisms (confirmation), immediately after instrumentation (1st collection), after 7 days of the BMP (2nd collection), after 14 days of the action of ICM (3rd Collection) and 7 days after removal of the ICM (4 th collection). Were performed: the evaluation of antimicrobial activity and the content analysis of endotoxins for all sampling tests. The results were statistically analyzed using Kruskall-Wallis and Dunn tests with a significance of 5%. It was found that the CLX as auxiliary chemical substance has significantly reduced microorganisms confirmation collection when compared. In relation to the neutralization of endotoxin, it was found that the 1st and 2nd collections presented a decrease of 92.03% and 98.10% in mean percentage respectively, when compared to the confirmation collection. In the 3rd and 4th samplings, the Ca (OH)2 + CLX group showed the best results. It was concluded that the BMP and the ICM were able to eliminate the tested microrganisms, however, they were not able to completely eliminate endotoxins root canal

Influência da clorexidina na capacidade de umectabilidade da dentina hígida e afetada por cárie por um sistema adesivo

To evaluate the effect of chlorhexidine (CHX) on the wettability of sound and caries affected dentin by a simplified adhesive system. Material and Methods: Flat coronal dentin surfaces were produced on 60 sound molars, 30 of which were artificially decayed. The teeth were divided randomly into 3 groups (n = 10) with smear layer (SL), without SL impregnated with water and without SL impregnated with chlorhexidine. The SL removal was performed by phosphoric acid etching for 15 s. 20 uL of distilled water or 2% chlorhexidine digluconate were applied on the demineralized dentin for 60 s. Then, a drop of Single Bond 2 was deposited on each surface. Contact angles between dentin surface and adhesive was measured by means of a goniometer and data were submitted to ANOVA and Tukey tests (α = 0.05). Results: Higher contact angles were obtained on sound versus caries affected dentin (p <0.05), regardeless of the surface treatment. For both substrates, contact angles statistically higher were obtained for dentin covered with SL (P <0.05). The SL removal resulted in significant reduction of the angles (P <0.05) and no difference was found among angles produced on demineralized dentin impregnated with water or chlorhexidine (p> 0.05). Conclusion: Caries affected dentin wettability was higher than sound dentin and that characteristic was not influenced by chlorhexidine application.
