About this study
Official title: Effect of Post-operative Chlorhexidine on Postoperative Pain and Complications After Surgical Removal of Mandibular Third Molars: a Randomized Controlled Trial
This study aimed to assess the impact of postoperative chlorhexidine use on pain management following mandibular third molar removal
In this prospective, randomized controlled trial,130 patients who underwent mandibular third molar surgical removal were divided into two groups: one group used chlorhexidine for postoperative rinsing and the other did not rinse. Pain levels, measured using the Numeric Rating Scale (NRS), were recorded daily for the first seven days post-surgery. Paired-samples t-tests were utilized for data analysis.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Chlorhexidine Digluconate Mouthwash without AlcoholOther
In the rinsing group, the patients received a bottle of 0,2% chlorhexidine
| Study group | Role | What they receive |
|---|---|---|
| Post-operative rinsing with chlorhexidine | Other | In the rinsing group, the patients received a bottle of 0,2% chlorhexidine Receives: Other: Chlorhexidine Digluconate Mouthwash without Alcohol |
| No post-operative rinsing | No intervention | Those allocated to the control group received no post-operative rinsing |
What is being measured
The primary outcome is the main question the study is designed to answer.
Postoperative pain after removal of third molar
The primary endpoint is the difference in the postoperative pain measured on a numerical rating scale (NRS) evaluated at seven days
Measured: 7 days after the inclusion pain was measured on a numerical rating scale
Secondary outcomes (1)
Post-operative complications
As secondary outcome measures alveolitis, foodimpaction, bleeding or infection
Measured: 7 days after the treatment the patient was seen at the outpatient clinic for clinical assessment. At this moment the number of patients with alveolitis, foodimpaction and bleeding was scored.
