Brief Summary

This project aims to study various predictive factors of postoperative pain after oral surgery among different parameters accessible preoperatively, in order to build a predictive model. It also aims to validate the external consistency of the Pain Sensitivity Questionnaire in an odontological context.

Detailed Description

This project aims to study various predictive factors of postoperative pain after oral surgery among different phenotypic parameters accessible to preoperative interrogation (anxiety about dental care, personal perception of pain sensitivity, gender, eye color, hair color, blood group) in order to build a predictive model. It also aims to validate the external consistency of the Pain Sensitivity Questionnaire (PSQ) in an odontological context, by studying the relationship between the personal perception of pain sensitivity (measured by the PSQ) and anxiety about dental care (measured by the Corah Dental Anxiety Scale), as well as dramatization in the face of pain (measured by the Pain Catastrophizing Scale).

GroupInterventionDescription
Open-label cohort, with short follow-upQuestionnairesThis is a collection of data from postoperative questionnaires and simple, non-invasive clinical observations. The oral surgery acts in question are performed in daily practice without any change in patient management. The intraoperative data collected come from routine care. Postoperative data (pain and analgesic intake) are collected by self-questionnaires and no visit on purpose is required.
Primary Outcome Measures
NameTimeMethod
Postoperative pain Day 1Information gathering on the evening of day 1

The pain will be measured from the collection of an intensity measured on a simple 11-point numerical scale (ENS) ranging from "0 = no pain" to "10 = the worst pain imaginable"

Postoperative pain Day 2Information gathering on the evening of day 2

The pain will be measured from the collection of an intensity measured on a simple 11-point numerical scale (ENS) ranging from "0 = no pain" to "10 = the worst pain imaginable"

Postoperative pain Day 3Information gathering on the evening of day 3

The pain will be measured from the collection of an intensity measured on a simple 11-point numerical scale (ENS) ranging from "0 = no pain" to "10 = the worst pain imaginable"

Postoperative pain Day 4Information gathering on the evening of day 4

The pain will be measured from the collection of an intensity measured on a simple 11-point numerical scale (ENS) ranging from "0 = no pain" to "10 = the worst pain imaginable"

Postoperative pain Day 5Information gathering on the evening of day 5

The pain will be measured from the collection of an intensity measured on a simple 11-point numerical scale (ENS) ranging from "0 = no pain" to "10 = the worst pain imaginable"

Secondary Outcome Measures
NameTimeMethod
Explanatory variable 1: Pain Sensitive Questionnaire1 time only before surgery

The Pain Sensitivity Questionnaire (PSQ) is a self-administered questionnaire comprising 17 items, each rated from 0 to 10. items n° 3-6-7-10-11-12-14 evoke moderately painful situations (and their sum makes it possible to calculate a "minor" PSQ score), and items n° 1-2-4-8- 15-16-17 evoke clearly painful situations (and their sum makes it possible to calculate a "moderate" PSQ score). The sum of these two scores is the "total" PSQ score. As each response to each item ranges from 0 to 10, the minimum value for all scores is 0, and the maximal ones for the minor, the moderate and the total PSQ scores are respectively 7, 7 and 14. The higher the scores, the higher the sensitivity to pain.

Explanatory variable 2: Corah's Dental Anxiety Scale (CDAS)1 time only before surgery

Corah's Dental Anxiety Scale is based on 4 main questions and calculates a score from 5 to 20 (0-8: no anxiety; 9-12: moderate anxiety; 13-14: high anxiety; 15-20: severe anxiety)

Explanatory variable 3: Pain Catastrophizing Scale (PCS)1 time only before surgery

Pain Catastrophizing Scale is based on 13 questions that cover 3 representative domains of dramatization: exaggeration of the pain felt (magnification), the tendency to constantly meditate on the pain (rumination) and the feeling of abandonment or lack of associated support (helplessness). As each response to each of the 13 responses items ranges from 0 to 4, the minimum value for the PCS score is 0, and the maximal is 52. The higher the score, the higher the level of pain catastrophizing.

Explanatory variable 4: Gender1 time only before surgery

Gender will be determined between male or female subject

Explanatory variable 5: Eye color1 time only before surgery

The color of the iris will be determined by the scale of Martine and Schultz:

Light tones:

1-2: Blue 3: Blue gray 4: Gray 5: Blue-gray with yellow/brown spots 6: Grey-green with yellow/brown spots 7: Green 8: Green with yellow/brown spots 9-10-11: Light brown or hazelnut brown

Dark tones:

12-13: Brown 14-15: Dark brown to black

Explanatory variable 6: Hair color1 time only before surgery

Hair color will be determined by color:

Black Brown Blond Red

Explanatory variable 7: Blood group1 time only before surgery

The blood group will be determined by the groups:

O HAS B AB as well as Rhesus + or -
