Detailed Description
Pain is the most common complication following surgical removal of an impacted mandibular third molar (SRM3). Acute postoperative pain (APP) following SRM3 is a normal physiological response to the tissue damage and usually treated sufficiently by paracetamol, non-steroidal anti-inflammatory drugs, or opioids. Increasing age, gender, smoking habit, length of surgery, type of anesthesia, intraoperative complications, surgeon's experience, and contamination of the surgical wound are well-known risk factors that affects the intensity and duration of APP. However, APP can transcript into postoperative chronic pain (PCP) without an explainable reason or a specific risk factor. Moreover, specific predictors for development of PCP following SRM3 is currently not sufficiently elucidated.
PCP is defined as pain lasting for two months or more after surgery, when other causes of pain are excluded. The characteristics and intensity of PCP varies among individuals and specific factors for developing PCP has not yet been clearly elucidated. PCP leads to severe functional limitations and impaired oral health-related quality of life (OHRQoL). The presence of pain prior to surgery as well as the intensity and duration of APP are considered as critical predictors for developing PCP. Various pharmacological and preventive strategies have therefore been proposed to minimize the risk of APP following SRM3 including modification of the surgical technique, sufficient intra- and postoperative pain control as well as preoperative psychological intervention focusing on the psychosocial and cognitive risk factors. Moreover, risk factors, such as genetic and epigenetic modifications have also been associated with APP and PCP. Among epigenetic modifications, non-coding RNAs have shown to be associated with the development of PCP. However, clarification of factors that specifically influence the development of PCP following SRM3 remains unknown.
Advanced platelet-rich fibrin (APRF) is a centrifuged fibrin matrix composed of concentrated growth factors, platelet cytokines, and blood cells, which possesses the ability to stimulate wound healing and tissue regeneration. Manufacturing of APRF from blood samples and application of APRF in the extraction socket following SRM3 have diminished the intensity and duration of APP and facilitated improved wound healing, as reported in systematic reviews and meta-analyses. Application of APRF in the extraction socket following SRM3 possess therefore the ability to minimize the risk of developing PCP due to a shorter period of APP.
The objective of the present study is therefore to identified specific predictors for developing PCP following SRM3. Eighty patients with an impacted mandibular third molar will be randomly allocated to SRM3 with or without application of APRF in the extraction socket. A standardized postoperative pain-management regime will be applied following SRM3. Blood samples (80mL) will be obtained intraoperative and one week postoperatively for all included patients. The investigated non-coding RNAs in the blood of participants will be used to assess their association with pain sensitivity and risk of developing PCP. Self-administrated questionnaires and visual analogue scale (VAS) will be used to correlate the results of the of non-coding RNA dysregulation with the duration and intensity of postoperative pain, social and working isolation, physical appearance, eating and speaking ability, diet variations, sleep impairment, and discomfort after one week, one month, and one year, respectively. The Modified Dental Anxiety Scale is used to measure preoperatively dental anxiety. OHRQoL is evaluated by self-administrated questionnaires obtained preoperatively and compared with postoperative assessment after one week, one month, and one year. The primary outcome measure is intensity and duration of postoperative pain following SRM3 with or without application of APRF in the extraction socket. These results will be correlated with alteration in non-coding RNAs expression to identified possible predictors for developing PCP. The results will be published in international peer-reviewed journals as well as presented at congresses.
