ObjectiveThis study investigated the effect of topical application of 0.12% chlorhexidine, 10% povidone-iodine and 50% erythromycin on the optimization of healing process of traumatic ulcers made on ventral tongue of rats.DesignForty-Eight Wistar rats were randomly divided into four groups: control, chlorhexidine (Chx), povidone-iodine (PvI) and erythromycin (Er). An ulcer of 5 mm in diameter was made on the ventral tongue of the animals. After 24 h, a microbiological sample was taken and daily application of the substances started. Six animals each group were euthanized at 4 days and the others at 8 days postoperative, totaling three and seven days of treatment. Prior to euthanasia, a new microbiological collection was performed.ResultsThe experimental groups showed less area of residual ulcer. A significant difference was seen between the PvI and Chx in relation to the control after three days of treatment (p<0.05). Although the experimental groups displayed greater newly formed epithelial area, there was no significant difference compared to the control (p>0.05). Er exhibed the lowest inflammation scores after seven days of treatment (p = 0.05). PvI showed reduction of microorganisms at both times and under aerobic (p < 0.01 at 3 days and p < 0.001 at 7 days) and microaerophilic (p<0.05) conditions. Er significantly reduced the count of microorganisms in aerobic condition when compared to control group (p<0.05 at 3 days and p<0.01 at 7 days).ConclusionsAll drugs promoted reduction of the microorganisms at the site of the injury, which may have a direct effect on the tissue repair process.
