Efficacy of aPDT in Reducing Pain and Swelling Following Molar Extraction Surgery- Blinded Randomized Controlled Clinical Trial

November 27, 2022 updated by: Livia Azeredo Alves Antunes, Universidade Federal Fluminense
This project aims to evaluate the effect of antimicrobial photodynamic therapy (aPDT) on the reduction of swelling and postoperative pain in lower molar extraction procedures. This is a clinical study approved by the Research Ethics Committee, which will be performed in 40 patients between 20 and 60 years. Patients included in the study should have at least one lower molar (first or second molar) with indication of exodontia. Participants will follow the exclusion criteria: pregnant or breastfeeding women; patients with obesity (Body Mass Index - BMI); make use of any activity smokers and ex smoker to 6 months; diabetics; immunosuppressed; in osteoporosis; making use of antimicrobials in the last 3 months; making use of medications that interfere with bone remodeling; with cysts or tumors in place. Surgical procedures that exceeded the clinical time of 30 minutes and / or required opening of the flap or osteotomy were excluded from the study. After the sample calculation, forty patients will be involved in this project, where forty molars (first and second molars) will be extracted in the mandible, which will be randomly divided into 4 groups. The control group (C.G), will contain 10 patients, where 10 molars will be extracted in a conventional way, without any additional treatment to be done. Test group 1 (T.G1) will contain 10 patients where 10 molars will be extracted and immediately after extraction, the fresh sockets will receive in their inner portion a local application of aPDT. The test group 2 (T.G2) will present 10 patients, where 10 molars will be extracted that immediately after the exodontia, the fresh socket will receive local application of infrared in the outer vestibular portion. Finally, Test Group 3 (T.G3), will be composed of 10 patients, where 10 molars will be extracted, joining the approaches of the previous groups (aPDT + infrared). Pain intensity will be assessed through a visual analogue scale and swelling assessed by measuring a perimeter between the tragus, the base of the jaw and the commissure of the lips. The data will be collected in four moments: before the surgery, 72 hours, 7 days and 30 days postoperatively.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
