Effectiveness of Light-emitting Diode (LED) Photobiomodulation in the Extraction of Retained Lower Third Molars
Pain, Postoperative, Edema, Trismus
About this trial
This is an interventional treatment trial for Pain, Postoperative
Eligibility Criteria
Inclusion Criteria:
- Patients who need surgical removal of retained lower third molars;
- Patients who agree to participate in the study after reading and signing the Term of Consent for Participation in Clinical Research.
- Patients with indication for extraction of lower third molars (recurrent infections, bad position, orthodontic indication) or written professional indication (ASA I - negative medical history), systolic blood pressure less than 140mmHg, and diastolic blood pressure lower than 90mmHg and heart rate values of 70 ± 20 beats / minute and have the upper and lower central incisor teeth.
Exclusion Criteria:
- Patients who have systemic diseases, chronic pain or neurological and psychiatric disorders;
- Claim to be smokers;
- Are using anti-inflammatories, analgesics or bisphosphonates in the last 15 days;
- Present active pericoronaritis;
- Are pregnant;
- are breastfeeding;
- Severe temporomandibular disorders
- Have photo sensitivity history
- Are allergic to any drug used in the research (paracetamol, chlorhexidine 2%)
- Patients presenting radiolucent images associated with the teeth to be extracted
- Patients who present any type of complication during surgery (hemorrhage, operative difficulty, time greater than 90 minutes of surgery), as these cases are not in the standard expected for third molar surgeries. In this case the central action analgesic will be prescribed. These data will not be part of the statistical analysis but will be described and discussed as well as possible adverse effects.

Sham group
The patients (n=17) will receive daily intra and extra oral LED applications from the immediate postoperative period up to 7 days after the surgical procedure. The LED irradiation will be performed in two areas, one intra and one extra oral. The LED to be used in the intraoral site will be red, 660+/-20nm wavelength, 5 mW power, 2.7J/cm2 energy density for 7 min, 2J energy per point, knowing that the 6 irradiated spots will have 12J in total. In the extra oral site the infra-red LED will be used, 850+/-20nm wavelength, power of 5mW, 3.8J/cm2 of energy density for 10 min, 3J of energy per point, knowing that 36 will be irradiated, so we will have 108J in total.
Patients (n=17) will be treated in the same way as the LED group. The person in charge of the application will simulate the intraoral and extraoral irradiation by positioning the LED in the same locations described for the LED group, but the equipment will be kept off. So that the patient does not identify the sound of activation of the device (beep), it will be recorded, and connected at the time of application.
