Effects of Photobiomodulation Conditioning in Impacted Third Molars

Effects of Photobiomodulation Conditioning of Orofacial Tissue in Surgery for Removal of Impacted Mandibular Third Molars: Randomized, Sham-controlled, Double-blind Clinical Trial

The removal of third molars should be considered to avoid problems such as cysts and other complications. Surgical intervention with the manipulation of oral tissues has the undesirable postoperative effects of pain, trismus (limited mouth opening) and edema. Photobiomodulation has also proved effective regarding reductions in pain, edema and trismus. The aim of the present study was to evaluate the effectiveness of photobiomodulation for the conditioning of tissues involved in the surgical removal of impacted mandibular third molars in terms of reducing or eliminating postoperative pain, trismus and edema.

Detailed Description

The investigator will select 62 patients from Nove de Julho Clinics, minimal 18 years old, with impacted third molar teeth. The volunteers will be randomly allocated to two groups using a block randomization process: photobiomodulation group (PG) and sham group (SG). The same surgeon and assistant performed all operations. The surgeon, assistant and patients will be all blinded to the LED treatment protocol. The participants in the active photobiomodulation group will be irradiated with infrared LED at a wavelength of 850 nm 08J 80 seconds perpendicular to the surface of the skin in gentle stationary contact at three extraoral points. For the participants in the sham group, a device with a similar appearance will be used that did not emit radiation. Treatment will be administered one hour prior to the surgical procedure as well as 48 hours and seven days (removal of sutures) after the first irradiation. The visual analog scale will be used for the measurement of pain intensity, facial measurements evaluated edema. Mouth opening range will be measured with sterilized manual calipers between the incisal edge of the maxillary and mandibular central incisors. The distribution of the data (normal or non-normal) will be determined using the Shapiro-Wilks test. Data with normal distribution will be analyzed using two-way repeated-measures analysis of variance (ANOVA), the t-test for two groups with independent measures and the paired t-test for two groups with dependent measures. Data with non-normal distribution will be analyzed using the Wilcoxon test for paired data and the Mann-Whitney test for independent data. Categorical data will be analyzed using Fisher's exact test for independent data and McNemar's test for paired data. The significance level will be set at α = 0.05.

Intervention / Treatment
EXPERIMENTAL: Photobiomodulation
The participants in the active photobiomodulation group will be irradiated with infrared LED at a wavelength of 850 nm perpendicular to the surface of the skin in gentle stationary contact at three extraoral points. Treatment will be administered one hour prior to the surgical procedure as well as 48 hours and seven days (removal of sutures) after the first irradiation.
Device: Infrared LED
The participants in the active photobiomodulation group will be irradiated with infrared LED at a wavelength of 850 nm perpendicular to the surface of the skin in gentle stationary contact at three extraoral points. Treatment will be administered one hour prior to the surgical procedure as well as 48 hours and seven days (removal of sutures) after the first irradiation.
SHAM_COMPARATOR: Sham Photobiomodulation
For the participants in the sham group, a device with a similar appearance will be used that did not emit radiation. Treatment will be administered one hour prior to the surgical procedure as well as 48 hours and seven days (removal of sutures) after the first irradiation.
Device: Similar device - Infrared ED
For the participants in the sham group, a device with a similar appearance will be used that did not emit radiation. Treatment will be administered one hour prior to the surgical procedure as well as 48 hours and seven days (removal of sutures) after the first irradiation.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Infrared Led.
Time Frame: Throught study completion, an average 48
In the immediate pre-surgery period, three measurements were taken on the face of the patient with a previously sterilized flexible metric tape (centimeters): tragus - pogonion; tragus - lip commissure; and angle of mandible - outer orbicular commissure. Mouth opening range was measured (centimeters) with sterilized manual calipers between the incisal edge of the maxillary and mandibular central incisors The visual analog scale was used for the measurement of pain intensity. Each patient marked a point along a line between two extremes numbered zero (no pain) to 10 (worst possible pain) to represent the pain felt at moment of evaluation (69,70).
