Abstract

Aim: To compare the impact of antibiotics on health‑related quality of life (QoL) outcomes following third molar surgery. Materials and Methods: The study population consisted of 135 subjects that required surgical extraction of mandibular third molar under local anesthesia and met the inclusion criteria. The subjects were randomized into three study groups of 45 subjects each: Group A ‑ extended amoxicillin/clavulanic acid (GlaxoSmithKline Beecham England), 1 gram pre-operatively and then 625 mg BD for 5 days Group B ‑ prophylactic amoxicillin/clavulanic acid (GlaxoSmithKline Beecham England) 1 gram pre-operatively only, and Group C ‑ prophylactic levofloxacin 1 gram preoperatively only. Patients were assessed pre‑ and post‑operatively on days 1, 3, 5, 7, and 14 using the United Kingdom oral health‑related QoL (OHRQoL) questionnaire. Results: This study showed that surgical removal of impacted teeth exerted a negative influence on patient’s QoL across various physical, social, and psychological aspects of life. Comparing the three groups, Group A showed a slightly better QoL score; although, there was no statistically significant difference among them. Studies have shown better clinical recovery following administration of antibiotics after third molar surgery. Conclusion: There was a significant deterioration in OHRQoL in the immediate postoperative period, particularly postoperative days 1 and 3 following third molar surgery. QoL was also observed to be slightly better in Group A than Groups B and C, although this was not statistically significant.
