Effects of an Experimental Propolis Gel on Tooth Sensitivity Control and Post-bleaching Color Change: a Randomized Clinical Trial
Effects of a 0.5% Experimental Propolis Gel on Tooth Sensitivity Control and Post-bleaching Color Change: a Randomized Clinical Trial
연구 개요
상태
상세 설명
All groups will undergo in-office whitening treatment, carried out in 2 sessions with a 7-day interval, according to the steps described below:
Prophylaxis; Application of gingival barrier; Application of desensitizing agent or placebo, according to the established groups; Handling of the whitening material following the manufacturer's instructions: application of Whiteness HP 35% whitening gel for 30 minutes Final removal of the whitening gel and gingival barrier, followed by rinsing with water.
The application of the desensitizing agent or its placebo will follow this sequence:
Relative isolation with cotton rolls; Active application of the product on the buccal surfaces of all teeth using a rubber cup for 10 minutes; Rinsing with water.

개입 / 치료 |
|---|---|
|
위약 비교기: Placebo- KY original gel
The Placebo group received the application of placebo gel for post tooth bleaching sensitivity.
|
Prior to bleaching treatment with 35% hydrogen peroxide, the Placebo group received the application of a placebo gel (without active ingredient), under the same conditions described for the experimental gel.
|
|
활성 비교기: KF2- Potassium nitrate
The KF2 group received the application of potassium nitrate for post tooth bleaching sensitivity.
|
Prior to bleaching treatment with 35% hydrogen peroxide, the dental elements of the KF2 received application of the potassium nitrate gel on the buccal surfaces of the central incisors, lateral incisors, canines and upper and lower premolars, for 10 minutes.
|
|
실험적: Propolis- Propolis 0,5% gel
The Propolis group received the application of experimental gel of propolis 0,5% for post tooth bleaching sensitivity.
|
Prior to bleaching treatment with 35% hydrogen peroxide, the dental elements of the Propolis received application of the experimental desensitizing gel on the buccal surfaces of the central incisors, lateral incisors, canines and upper and lower premolars, for 10 minutes.

Post-whitening sensitivity assessment
기간: 14 days
|
To assess post-operative sensitivity, patients will be instructed to fill out a form to record daily tooth sensitivity during the 14 days of treatment, based on their individual perception of pain.
This form will be handed out at each whitening session and returned to the researcher at the following session, that is, always one week after each whitening session.
The assessment form will consist of a visual analogue scale (VAS).
This scale consists of a 10 cm horizontal line with scores of 0 and 10 at its ends, where 0 means no sensitivity and 10 means severe tooth sensitivity.
The patient will be instructed to draw a vertical line along the horizontal line of the scale, recording the intensity of tooth sensitivity per day.
So that the distance in millimeters from the zero end can later be measured with the aid of a millimeter ruler, thus obtaining the patient's pain intensity level.

Color evaluation
기간: Baseline (T0) and one week after the 2rd whitening session (T1)
|
The VITA Easyshade spectrophotometer (VITA Zahnfabrik, Bad Säckingen, Germany) will be used to measure the color, where the area of dental correspondence to be evaluated will be the middle third of the vestibular surface of the upper canines.
To standardize the color readings, silicone matrices will be made, where the impression will be extended from canine to canine.
A window will be created on the vestibular surface of each canine of the silicone guide using a metal device with a radius of 6 mm, 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 the baseline (T0) and one week after the 2rd bleaching session (T1) will be calculated using the CIEDE2000 formulas (ΔE00).
