Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The volunteer participants were divided into 2 groups using the Block Randomization method as follows:
Group 1: Participants in this group were administered with 500 milligrams of Paracetamol after tooth extraction. They were instructed to take 1 tablet every 6 hours, totaling 10 tablets.
Group 2: Participants in this group were administered with 400 milligrams of Ibuprofen after tooth extraction. They were instructed to take 1 tablet after meals, totaling 10 tablets.
Both groups of volunteers will receive a checklist to remind them to take their medication as prescribed by the dentist and volunteers must bring the checklist to the dentist on the follow-up day.

Outcomes

Modified Landry Turnbull and Howley indices (LTHI)
Timepoint [1] 337454 0
3 days and 7 days (primary timepoint) after tooth extraction.
Primary outcome [2] 337455 0
Concentration of MMP-9 (pg/ml) and TGFß1 (pg/ml).
The concentration of MMP-9 (pg/ml) and TGFß1 (pg/ml) indicates the level of wound healing. In cases where the wound heals well, there should be a low concentration of MMP-9 (pg/ml) and a high concentration of TGFß1 (pg/ml). Conversely, if wound healing is poor, there will be a high concentration of MMP-9 (pg/ml) and a low concentration of TGFß1 (pg/ml). MMP-9 and TGFß1 will be assessed together as a composite primary outcome.
Timepoint [2] 337455 0

Eligibility
Key inclusion criteria
For the inclusion criteria, subjects were selected as patients who need to remove upper third molar tooth within an age range of 15-30 years, who were of healthy status (American Society of Anesthesiologists: ASA class I and II), and who reported a normal body mass index (BMI) within a range of 18.5-24.5 kg/m2. In addition, they were free from pathological conditions, denied having any history of chronic illnesses and drug allergies.
Minimum age
15 Years
Maximum age
30 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
The terms of exclusion were as follows: 1) Patients who were pregnant, heavy smokers, allergic to paracetamol, ibuprofen, or any anesthetic medications (e.g., mepivacaine and epinephrine-related drugs). 2) Patients who had undergone any pre-existing medical conditions such as hypertension, diabetes, liver disease, kidney disease, blood clotting disorders, and gastritis. 3) Patients who had wounds/injuries in various parts of their bodies prior to initiating the experimental study or those that had severe gingival inflammation (Gingival index > 2). 4). Patients who had taken medication or dietary supplements that could impact the wound healing process. 5) Patients who experienced psychological or communication disorders.

Efficacy
Statistical methods / analysis
Sample size was calculated according to the data obtained from the previous correlated study using the STATA® version 16.0 software (StataCorp, LLC, College Station, TX, USA). Initially, the total sample size was comprised of 16 individuals, who were then divided into two groups (n = 8 each). However, the researchers decided to increase the sample size to a total of twenty individuals, which were then divided into two groups (n = 10 each) by including additional participants.
Results were analyzed and expressed as interquartile range (IQR) using the STATA® version 16.0. Median concentrations of MMP-9 and TGF-beta1 in the saliva samples collected at different time points among patients who received paracetamol and ibuprofen were determined and compared using Mann-Whitney U test at a 95% confidence level. Proportions of LTHI values between patients who had received paracetamol and ibuprofen were determined and compared using Fisher’s exact test at a 95% confidence level. The relationship between LTHI values, MMP-9 concentrations, and TGF-beta1 concentrations were determined and compared using Spearman’s correlation coefficient at a 95% confidence level. Accordingly, at least p < 0.05 was considered significantly different.
