Abstract
BACKGROUND AND AIM
The surgical extraction of impacted wisdom teeth is a standard practice in dentistry. Unfortunately, inflammatory reactions such as discomfort, edema, and trismus frequently jeopardize patients' well-being after the extraction of third molars. Saline solutions at room temperature (25°C) are routinely used in impacted tooth extraction. Refrigerated saline solutions were used to work with cold solutions, and as the refrigerator temperature was 4°C, this study was designed to have a cold solution temperature of 4°C. This study aimed to assess the influence of saline irrigation at various temperatures (4°C, 25°C) on postoperative edema, pain, and trismus after the extraction of impacted third molars.
MATERIALS AND METHODS
Eighteen patients with bilateral symmetrical mandibular impacted third molars were enrolled in this split-mouth, randomized, prospective, double-blind clinical trial. For each patient, one side was irrigated with a saline solution (% 0.9 isotonic sodium chloride) at 4°C (test), and the other side was irrigated with a saline solution at room temperature (25°C) (control). Pain, trismus, and facial edema were noted on the 2nd, 4th, and 7th days. A Mann-Whitney U-test was used to compare pairs, and a Wilcoxon signed-rank test was used to compare groups.
RESULTS
The two groups had no considerable differences in terms of pain levels and facial edema (P > 0.05). Regarding trismus, the maximum mouth opening for cold irrigation (4°C) was significantly higher than for room temperature irrigation (25°C) across all postoperative periods (P < 0.05).
CONCLUSION
Cold irrigation therapy (4°C) exerts beneficial effects more than room temperature (25°C) irrigation on the trismus after impacted mandibular third molar surgery.
