Comparison of the influence the amount of sterile normal saline solution in reducing the postoperative complications after third molar surgery

OBJECTIVE: This study aimed to determine the optimal amount of serum used for reducing complications after impacted lower third molar surgery. METHODS: This study was performed as a randomized clinical trial with patients requiring mandibular third molar surgery. Patients with random selection were divided into 1of 3 intervention groups: intervention group A received 20 ml of normal saline 0.9% as irrigation solution of socket and B intervention group and C intervention group received 40 and 60ml of normal saline0.9%, respectively. Pain intensity, swelling, change in normal daily activities, General patient satisfaction were assessed on the 2 and 7 days after surgery. The pain was measured using a visual analog scale(VAS) and the number of analgesic tablets consumed. Data were analyzed using Kruskal-Wallis analysis and analysis of variance (ANOVA). P value<.05 was considered significant. RESULTS: A total of 330 patients had a mean age of 25.6 years, 95% male .There was a significant difference between the amount of pain, swelling, satisfaction and change of mouth smell on the 2 and 7 days after surgery in the between 3 groups (P<0.05). There was no significant difference between the rate of change in the quality of life on the 2 and 7 days after surgery in the between 3 groups (P>0.05). CONCLUSIONS: According to the findings of the present study, it seems that the use of low serum levels can reduce the amount of pain, general satisfaction and mouth smell after surgery and increase swelling scores.
