Design outcomes

Secondary

MeasureTime frame
Expected outcome 2: It was expected that the active oxygen gel would result in lower postoperative pain after mandibular third molar extraction when compared with 0.2% chlorhexidine bioadhesive gel, assessed using the Visual Analog and Numeric Scale on postoperative days 1, 3, and 7.;Found outcome 2: Postoperative pain progressively decreased throughout the follow-up period in both groups, with no statistically significant difference between treatments on the evaluated days. A slight trend toward lower pain scores was observed in the active oxygen gel group during the early postoperative period.;Expected outcome 3: It was expected that the active oxygen gel would result in lower postoperative facial edema after mandibular third molar extraction when compared with 0.2% chlorhexidine bioadhesive gel, assessed by linear facial measurements before surgery and on the seventh postoperative day.;Found outcome 3: Facial edema showed no statistically significant difference between the active oxygen gel and 0.2% chlorhexidine bioadhesive gel groups, demonstrating similar postoperative evolution between treatments.;Expected outcome 4: It was expected that the active oxygen gel would be associated with a lower occurrence of trismus on the seventh postoperative day after mandibular third molar extraction when compared with 0.2% chlorhexidine bioadhesive gel, assessed by maximum mouth opening measurement.;Found outcome 4: The occurrence of trismus on the seventh postoperative day was similar between the active oxygen gel and 0.2% chlorhexidine bioadhesive gel groups, with no significant difference between treatments.;Expected outcome 5: It was expected that the active oxygen gel would reduce the need for postoperative analgesic use after mandibular third molar extraction when compared with 0.2% chlorhexidine bioadhesive gel, assessed by recording paracetamol consumption during the seven postoperative days.;Found outcome 5: Paracetamol consumption was similar between the active ox

Primary

MeasureTime frame
Expected outcome 1: It was expected that the active oxygen gel would promote better soft tissue healing on the seventh postoperative day after mandibular third molar extraction when compared with 0.2% chlorhexidine bioadhesive gel, assessed using the Landry et al. healing index.;Found outcome 1: Soft tissue healing on the seventh postoperative day after mandibular third molar extraction was similar between the active oxygen gel and 0.2% chlorhexidine bioadhesive gel groups, with no statistically significant difference between treatments, as assessed using the Landry et al. healing index (p = 0.5385).
