Abstract
The effect of five intracanal dressings, calcium hydroxide, chlorhexidine gluconate (1% gel and 0.2% solution), camphorated parachlorphenole and 1% metronidazole was tested in vitro in four media. The canals of 40 test teeth were artificially infected with Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans. Significant differences were observed between five intracanal dressings regarding the number of P. aeruginosa after 3 and 7 days (p < 0.05) and C. albicans after 3 days (p < 0.05). Specimens with calcium hydroxide and camphorated parachlorphenole have significant antibacterial efficacy. Camphorated parachlorphenole has significantly reduced the number of all tested microorganisms P. aeruginosa and C. albicans after 3 and 7 days in comparison with other materials (p < 0.05). Calcium hydroxide has shown similar effect on P. aeruginosa as camphorated parachlorphenole regarding the efficacy after 3 days (p < 0.05). Chlorhexidine gel has shown the weakest efficacy on P. aeruginosa after 3 days, compared to all tested materials, but its antibacterial efficacy after 7 days was statistically greater compared to other materials (p < 0.05), except for camphorated parachlorphenole. All tested materials had good antimycotic efficacy against C. albicans except metronidazole that, as was expected, had no efficacy against yeast (p < 0.05). We can conclude that the antibacterial efficacy of chlorhexidine gel is enhanced with time, while camphorated parachlorphenole and calcium hydroxide have fastest and strongest antimicrobial efficacy.
