ABSTRACT
Aim
This randomized clinical trial compares the usefulness of adjunctive antibiotics, while strict asepsis was followed during periodontal surgery involving guided tissue regeneration.
Materials and methods
Two groups of 20 consecutive patients each with advanced periodontal disease were randomly assigned to treatment. They displayed one angular defect each with an intrabony component ≥3 mm, probing pocket depth and probing attachment level (PAL) ≥7 mm. Test group included 13 males, mean age 60 years, treated with enamel matrix derivative (EMD) and demineralized freeze-dried bone allograft with modified papilla preservation technique, received oral amoxicillin 1 gm, 1 hour preoperatively and 2 gm for 2 days postoperatively. Control group included 10 males, mean age 57 years, treated with EMD and demineralized freeze-dried bone allograft with modified papilla preservation technique, received no antibiotics.
Outcome measures were clinical attachment level (CAL) gain, residual periodontal pocket depth (res. PD), gingival recession (GR), bleeding on probing (BOP), adverse events and postoperative complications.
Patients were followed up to 12 months after periodontal surgery involving guided tissue regeneration.
Results
There were no significant differences between both groups for CAL gain, res. PD, GR, BOP nor other clinical parameters, though patients’ subjective perception of postoperative discomfort was significantly smaller in the group receiving antibiotics.
Conclusion
Antibiotics do not provide significant advantages concerning clinical periodontal parameters nor concerning postoperative infections in case of proper asepsis. It does, on the contrary, reduce postoperative discomfort.
Clinical significance
Regarding the results of this study, adjunctive systemic antibiotics in combination with guided tissue regeneration may be useful in reducing postoperative discomfort but may not be helpful for improving periodontal regeneration outcomes.
