Brief summary
The present clinical trial randomized will be to assess the link between the different haplotypes of CYP2C8 and CYP2C9 genes and the clinical efficacy of ibuprofen after lower third molar extractions. Onset, duration of postoperative analgesia, duration of anesthetic action on soft tissues, intraoperative bleeding, hemodynamic parameters, postoperative mouth opening and wound healing at the 7th postoperative day were evaluated. For this purpose, 200 healthy volunteers underwent removal of one lower third molar, under local anesthesia with articaine 4% (1:200,000 adrenaline) will be genotyped and phenotyped for these genes and their postoperative records with all data collected will be compared with the haplotypes found in the Brazilian population.
Detailed description
The aim of this study will be to assess the link between the different haplotypes of CYP2C8 and CYP2C9 genes and the clinical efficacy of ibuprofen after lower third molar extractions regarding pain, swelling and trismus, adverse reactions, the amount of pain medication used, the patient satisfaction with the drug and the influence of the ability on preoperative modulation of conditioned pain. We will evaluate also the relationship between the different haplotypes of OPRM1 gene (SNP A118G), the salivary concentrations of pro-inflammatory cytokines (IL-2, IL-4, IL-6, IL-10 and TNF-±), and preoperative conditioned pain modulation. Therefore, 200 patients will be genotyped and phenotyped for these genes and their postoperative records with all data collected will be compared with the haplotypes found in the Brazilian population. For analysis of the proposed genes, saliva will be collected, which will serve as a source of genomic DNA. For molecular analysis it will be performed polymerase chain reaction (PCR). All tests will be conducted and validated by Applied Biosystems®. Also it will be held in the research, genetic sequencing of the genes CYP2C8, CYP2C9 and OPRM1, to verify possible correlations of these genes with postoperative pain and pain modulation.

Intervention model description
Two Hundred healthy volunteers underwent removal of one lower third molar, will be treated to control pain, swelling and trismus with ibuprofen 600mg. Therefore, these 200 patients will be genotyped and phenotyped for these genes and their postoperative records with all data collected will be compared with the haplotypes found in the Brazilian population.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Subjective evaluation of postsurgical pain at the moment of the rescue medication utilization | Seventh postoperative day | Subjective evaluation of postsurgical pain at the moment of the rescue medication consumption which was annotated by the volunteer after the surgery, in a Visual Analogue Scale (VAS, 0-100 mm). |
| Quality of anesthesia | During the surgical procedure | Quality of anesthesia during surgery based on a category 3point scale: 1) the patient reported no discomfort; 2) the patient reported discomfort, without the need to supplement the anesthesia; 3) reported some discomfort by the patient, requiring anesthesia complementation. Intraoral bleeding that will be evaluated by the surgeon according to a 3point scale (1: minimal, 2: normal and 3: Maximum), immediately after the following steps: injection of the first cartridge anesthesia, incision, mucoperiosteal detachment, osteotomies, tooth section, extraction, cleaning and suturing. |
| Intraoperative bleeding during the surgeries steps | During the surgical procedure | Intraoperative bleeding, rated by the surgeon according to a 3 point category rating scale (1 minimal bleeding; 2 normal bleeding; 3 excessive bleeding) (SISK, 1986), immediately after the following steps: injection of the first cartridge of articaine, tissue incision, flap reflection, bone removal (when this procedure was necessary), tooth extraction, cleaning of the operated site, and completion of suturing. |
| Blood pressure variability during the surgeries steps | During the surgical procedure | Systolic blood pressure, diastolic, and mean to be verified and recorded at surgical moments previously described (injection of the first cartridge anesthesia, incision, mucoperiosteal detachment, osteotomies, tooth section, extraction, cleaning and suturing), carried out with the aid of a system for monitoring hemodynamic parameters. |
| Heart rate variability during the surgeries steps | During the surgical procedure | Heart rate to be verified and recorded surgical at moments described above, carried out with the aid of a system for monitoring hemodynamic parameters. |
| Oxygen saturation variability during the surgeries steps | During the surgical procedure | Oxygen saturation to be verified and recorded at surgical moments described above, carried out with the aid of a system for monitoring hemodynamic parameters. |
| Evaluation of changes in the postsurgical pain during the first 24 hours until 96 hours after the procedure | Seventh postoperative day | Subjective evaluation of postsurgical pain, which was annotated by the volunteer after the surgery, in a Visual Analogue Scale (VAS, 0-100 mm). The subjective pain evaluations will be performed by patients at the following times after administration of the drug \[0, 15, 30 and 45 min, 1; 1.5; 2; 3; 4; 5; 6; 7; 8; 10; 12; 16; 24 hr, 48, 72 and 96 h\]. What will be taken into account on this outcome is the representation of the postsurgical pain, that will be noted on the Visual Analogue Scale (in millimeters) in respective moments. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Onset and duration of surgery after administration of local anesthetic | During the surgery | Will only be considered those surgeries in which there is no difference in the duration time of the procedure between the patients. This time count will be started after the administration of the first local anesthetic. Unit of mesure used will be hours. |
| Incidence, type and severity of adverse reactions after the surgery | Seventh postoperative day | Will be considered as adverse reactions: gastrointestinal irritation, nausea, vomiting, bleeding, allergy, headache, dizziness, drowsiness or any other type of reaction presented after surgery. |
| Total amount of rescue medication | Seventh postoperative day | The total amount of rescue medication that was used by the patient during the postoperative period (Acetominophen- 750 mg) will be analyzed. |
| Measurement the facial edema | On the second day after surgery and on the seventh day after surgery. | It will apply the method used by Ustun et al. (2003), which takes into account the sum of the following measures (obtained with flexible tape measure): A) distance between the lateral corner of the eye and the gonion, B) away from the tragus corner of the mouth and C) away from the tragus to the soft tissue of pogonion. Preoperative sum of three measures will be considered as the baseline that way. The difference between the values obtained in the postoperative period and baseline indicate the facial edema in the 2nd and 7th days. |
| Postoperative mouth opening | Second and Seventh postoperative days | Mouth opening (mm) between the mesial-incisal corners of the upper and lower right central incisors at maximum opening of the jaws was measured and recorded before the surgery and during the second and seventh postoperative days. |
