Interventie / Behandeling |
|---|---|
|
Placebo-vergelijker: Placebo
The placebo group received an application of placebo gel for the control of post-bleaching tooth sensitivity.
|
Before bleaching treatment with 35% hydrogen peroxide, participants in the placebo group received a placebo gel without active ingredients, applied under the same conditions described for the experimental gel.
|
|
Actieve vergelijker: KF2 - Potassium nitrate
The KF2 group received an application of 5% potassium nitrate and 2% sodium fluoride for the control of post-bleaching tooth sensitivity.
|
Prior to bleaching treatment with 35% hydrogen peroxide, participants in the KF2 group will receive an application of a desensitizing gel containing 5% potassium nitrate and 2% sodium fluoride on the labial surfaces of the maxillary and mandibular central incisors, lateral incisors, and canines, and on the buccal surfaces of the maxillary and mandibular premolars, for 10 minutes.
|
|
Experimenteel: Jucá - Libidibia ferrea gel
The Jucá group received an experimental 0.5% Libidibia ferrea gel for the control of post-bleaching tooth sensitivity.
|
Prior to bleaching treatment with 35% hydrogen peroxide, participants in the Jucá group will receive an application of the experimental 0.5% Libidibia ferrea gel on the labial surfaces of the maxillary and mandibular central incisors, lateral incisors, and canines, and on the buccal surfaces of the maxillary and mandibular premolars, for 10 minutes.

Post-whitening sensitivity assessment
Tijdsspanne: 14 days
|
To assess postoperative sensitivity, patients will be instructed to complete a form to record daily tooth sensitivity during the 14-day treatment period, based on their individual perception of pain.
This form will be provided at each bleaching session and returned to the researcher at the following session, that is, one week after each bleaching session.
The assessment form will include a visual analog scale (VAS), consisting of a 10-cm horizontal line with scores of 0 and 10 at its ends, where 0 indicates no sensitivity and 10 indicates severe tooth sensitivity.
Patients will be instructed to draw a vertical mark along the horizontal line of the scale to record the intensity of tooth sensitivity each day.
Subsequently, the distance in millimeters from the zero endpoint will be measured using a millimeter ruler, thereby obtaining the patient's pain intensity score.

Color evaluation
Tijdsspanne: Baseline (T0) and one week after the second bleaching session (T1)
|
The VITA Easyshade spectrophotometer (VITA Zahnfabrik, Bad Säckingen, Germany) will be used for color measurement.
The evaluated tooth area will be the middle third of the labial surface of the maxillary canines.
To standardize color readings, silicone matrices will be fabricated, with the impression extending from canine to canine.
A window will be created on the labial surface of each canine in the silicone guide using a metal device with a 6-mm diameter, corresponding to the diameter of the spectrophotometer tip.
Thus, the tip of the device will be inserted into the silicone guide to obtain the color parameters.
Subsequently, the color difference between baseline (T0) and one week after the second bleaching session (T1) will be calculated using the CIEDE2000 formula (ΔE00).
