Effects of Irrigation Solutions at Different Temperatures Used in Mandibular Third Molar Surgery

17 settembre 2026 aggiornato da: Sara SAMUR ERGÜVEN., Saglik Bilimleri Universitesi

A Comparison of the Effects of Irrigation Solutions at Different Temperatures Used in Oral Surgery on Postoperative Complications and Oral Health-Related Quality of Life

The present study aims to compare the effects of saline, chlorhexidine, and hydrogen peroxide irrigation solutions at different temperatures on postoperative complications, including pain, swelling, and mouth opening, as well as oral health-related quality of life, in patients undergoing surgical extraction of impacted mandibular third molars. The irrigation solutions will be applied immediately following surgical tooth extraction at temperatures of either 4°C or 25°C.

An a prior power analysis based on repeated-measures analysis of variance (Repeated Measures ANOVA, within-between interaction) was performed. An effect size of f = 0.25, a Type I error rate (α = 0.05), and a statistical power of 1 - β = 0.95 were assumed.

Based on the power analysis, a minimum of 11 participants per group was determined to be sufficient. Considering potential loss to follow-up and missing data, the sample size was increased by approximately 15%, and it was decided to enroll 13 participants in each group. Accordingly, the planned study will be conducted with a total of 78 participants allocated to six groups, and all participants will be evaluated at four different time points.

Descrizione dettagliata

The removal of mandibular third molars is among the most common procedures carried out in oral surgery. After extraction, patients often experience postoperative complications such as pain, swelling, and limited mouth opening. If these complications become more severe, they can negatively impact the patient's oral health-related quality of life.

In mandibular third molar surgery, following elevation of the soft tissue flap to gain access to the tooth, bone removal is performed using high-speed rotary instruments with continuous irrigation using physiological solutions . Following bone removal and exposure of the tooth, the extraction is performed. Subsequently, irrigation of the extraction socket with physiological saline or antiseptic solutions has been recommended. After socket irrigation and evaluation of the bony structures, the surgical site is sutured and postoperative instructions are provided to the patients.Although the aforementioned studies have demonstrated that socket irrigation may produce favorable postoperative outcomes, to the best of our knowledge, no study has evaluated the effectiveness of irrigation solutions used at different temperatures for socket irrigation.Therefore, the present study aims to compare the effects of saline, chlorhexidine, and hydrogen peroxide irrigation solutions at different temperatures on postoperative complications, including pain, swelling, and mouth opening, as well as oral health-related quality of life, in patients undergoing surgical extraction of impacted mandibular third molars. The irrigation solutions will be applied immediately following surgical tooth extraction at temperatures of either 4°C or 25°C.

The present study aims:

  1. To evaluate the effectiveness of 0.2% chlorhexidine gluconate and 1.5% hydrogen peroxide irrigation solutions at temperatures of 4°C or 25°C, compared with saline irrigation at the corresponding temperatures, on postoperative complications, including pain, mouth opening, and swelling, following mandibular third molar surgery.
  2. To evaluate the effectiveness of 0.2% chlorhexidine gluconate and 1.5% hydrogen peroxide irrigation solutions at temperatures of 4°C or 25°C, compared with saline irrigation at the corresponding temperatures, on oral health-related quality of life following mandibular third molar surgery.

Accordingly, the planned study will be conducted with a total of 78 participants allocated to six groups, and all participants will be evaluated at four different time points.
