Outcome Measures

Primary Outcomes (1)

  • Remaining wound area analyzed through photographs

    The defect area was measured after 90 post-operative days. For this, standardized photographs were taken (in terms of brightness, distance, and angle). A scale was used as a reference to measure the area. These photographs were exported to image software (Image J-NIH, Bethesda, USA), and the wound area was measured in square millimeters (mm²)

    3 months

Secondary Outcomes (2)

  • Tissue colorimetric evaluation analyzed through photographs

    3 months

  • Presence or absence of scars or keloids

    3 months

Other Outcomes (1)

  • Tissue brightness evaluation

    3 months

Study Arms (3)

Free gingival graft + PBM Sham

SHAM COMPARATOR

The patients allocated to the control group will receive sham irradiation. For this, black rubber protection will be placed at the tip of the laser device, which do not allow the light to reach the tissue. The applications will be performed by a different operator from the one who will measure the study parameters. During irradiation, the tip of the laser probe will be placed perpendicularly with slight contact on the area. Laser therapy will be initiated in the immediate postoperative period (just after sutures) and will be repeated by four more applications performed every other day, with a total of 5 laser applications.

Procedure: Free gingival graftDevice: GaAlAs laser

Free gingival graft + GaAlAs Laser 60

EXPERIMENTAL

The irradiation will be performed with a GaAlAs diode laser that continuously emits a wavelength of 660 nm with a power of 30 milliwatts (mW). The patients allocated for the group 60 will receive the following protocol for laser application: Five (5) points of irradiation will be performed using a total energy density (fluence) of 60 Joules/cm2 and a time of 56 seconds per point (1,68 Joules/cm2 per point). During irradiation, the tip of the laser probe will be placed perpendicularly with slight contact on the area. Laser therapy will be initiated in the immediate postoperative period (just after sutures) and will repeated by four more applications performed every other day, with a total of 5 laser applications. The power of the equipment will be calibrated prior to each application.

Procedure: Free gingival graftDevice: GaAlAs laser

Free gingival graft + GaAlAs Laser 15

EXPERIMENTAL

The irradiation will be performed with a GaAlAs diode laser that continuously emits a wavelength of 660 nm with a power of 30 milliwatts (mW). The patients allocated for the group 15 will receive the following protocol for laser application: Five (5) points of irradiation will be performed using a total energy density (fluence) of 15 Joules/cm2 and a time of 14 seconds per point (0,42 Joules/cm2 per point). During irradiation, the tip of the laser probe will be placed perpendicularly with slight contact on the area. Laser therapy will be initiated in the immediate postoperative period (just after sutures) and will be repeated by four more applications performed every other day, with a total of 5 laser applications. The power of the equipment will be calibrated prior to each application.

Eligibility Criteria

Age20 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients presenting indication of anterior maxillary exodontia (15 to 25), with normal gingival contour in the teeth indicated for exodontia; The tooth included in the study, as well as the adjacent teeth do not present a loss of periodontal insertion.
  • Patients agreed to and signed the formal consent to participate in the study after receiving an explanation of risks and benefits from an individual who was not a member of the present study (Resolution no. 196 - October, 1996, and Ethics and Code of Professional Conduct in Dentistry - 179/93).

You may not qualify if:

  • Were excluded patients with systemic problems that contraindicated surgical procedure
  • Those under medication that could interfere with the wound healing
  • Those who smoked
  • Those who were pregnant or lactating, and
  • Those who had had periodontal surgery on the study area.
