Measurements with LDF in group A and B will be performed on the day of surgery before anesthesia and in the postoperative days of 3, 7, 14 and 28 days. To standardize the position (location and angulation) of the LDF probe relative to the gingival tissue at different evaluation times, the measurements will be performed with the aid of an individual acrylic guide supported on the tooth with perforations for fitting the point of the fiber optic probe (Donos et al., 2005; Retzepi M, 2007). In this way, the LDF probe will be inserted perpendicular to the tissues with a distance of 0.5 mm from the gingiva, remaining immobile during repeated measurements. In order to perform these measurements, patients will be comfortably accommodated in a standard semi-cline position, in the same dental chair, in a calm environment with a constant temperature (23 ± 20oC). Measurements will be performed by the same operator who has been properly calibrated and blinded to the experimental groups.
