“…Pal e found a shade change of À3.75 to À4.87 using 28% hydrogen peroxide with a light-emitting diode activation (15). Others have found shade changes from À6.1 to À11 measuring with Vita shade tabs (6,22). While the shade change was less than in other studies, gum chewing did not inhibit the whitening activation because all three groups had similar average shade changes.…”

“…While the shade change was less than in other studies, gum chewing did not inhibit the whitening activation because all three groups had similar average shade changes. Not all studies evaluating shade change use an objective measurement, and many employ the Vita Classical Shade Guide tabs that rely on the human eye (6,11,19,22,27). The use of a spectrophotometer offered an objective measurement of tooth shade (28,29).…”

“…Another mechanism to decrease sensitivity is the use of a glutaraldehyde and 2-hydroxyethyl methacrylate desensitizer. Glutaraldehyde and 2-hydroxyethyl methacrylate were placed on the labial surfaces of teeth before in-office whitening was shown to significantly reduce sensitivity compared to a placebo (22). While many of these treatment options have shown to reduce sensitivity with whitening, the incidence of sensitivity is still prevalent, most notably during in-office whitening procedures.…”

“…Another clinical trial (MEHTA et al, 2013) compared tooth sensitivity during and after bleaching with hydrogen peroxide gel following application of GLUMA Desensitizer PowerGel or placebo. The results, once again, showed that prebleaching application of the desensitizing agent significantly reduced tooth sensitivity during and after bleaching when compared with treatment with placebo.…”

ABSTRACT:The objective of this clinical study was to determine the effect of adding desensitizing agents in homemade experimental whitening gel Carbamide peroxide 16%. 60 young patients were selected (between 18-28 years), who used randomly (by lottery) the whitening gel DA (with desensitizing agent) or whitening gel CO (without desensitizing agent) characterized as control of a double-blind study, ie the patient and the evaluator did not know the product that was being used. Teeth 15, 14, 13, 12, 11, 21, 22, 23, 24 and 25 were bleached. The guidelines of how to apply the bleaching agents were performed by an experienced and calibrated team, and the application accompanied by examiners in several phases. To measure the color we used a Visual Range Vita Classical through visual inspection by the evaluators and patient information. A comparative test regarding each individual stimulation caused by mechanical attrition and thermal probe with clinical test was done (air syringe) in order to verify the presence of sensitivity in three phases: before treatment, after 7 and 14 days. Data were collected using Visual Analogue Scale (VAS) adapted to four criteria: no pain, mild pain, moderate pain and severe pain. The correlation of the data x teeth sensitivity were obtained separately, and tabulated for further comparative analysis. The results showed that there was no difference between the groups in terms of bleaching effect. In the post-operative sensitivity test, the subjects who used the product without desensitizing showed higher levels of sensitivity in different types of teeth, regardless of sex or age. It was concluded that the addition of desensitizing agent in the carbamide peroxide 16% whitening gel produced less post-bleaching sensitivity index. We emphasize that from the teeth evaluated, the premolars showed higher sensitivity index, followed by the canines and incisors. There was no difference in the bleaching capacity of the products used, demonstrating that the addition of desensitizing did not affect the efficacy of the treatment.

“…Although it could be mostly mild or moderate, it is at times so severe that the treatment is discontinued. [4] Enamel is generally considered to be impermeable. Nevertheless, the oxidative free radicals generated from hydrogen peroxide have low molecular weight and are able to denaturize proteins.…”

Background/Purpose: The eff ect of bleaching agents on dental hard tissues was uncertain. Moreover, reverting the side eff ects caused by bleaching using nutraceuticals as remineralizing agents remained uninvestigated. Hence, the aim of this study was to evaluate the eff ect of 22% carbamide peroxide (CP) on the mineral content of enamel and to evaluate the remineralization of bleached enamel after treatment with three diff erent remineralizing agents. Materials and Methods: A total of 30 extracted human maxillary incisors were selected, and their initial mineral content was analyzed using scanning electron microscopy with energy dispersive X-ray spectroscopy (EDX). All the specimens were bleached with 22% CP and their mineral content was reanalyzed. They were then randomly divided into three groups. Group A: Remineralization with casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), Group B: Remineralization with a 6.5% grape seed extract (GSE) solution prepared in phosphate buff er, and Group C: Remineralization with 6.5% wheat grass solution in phosphate buff er. Remineralization was carried out for 10 min, and EDX analysis was carried out again. Statistical analysis was done using oneway ANOVA and Student's t-test. Results: Bleaching with 22% CP signifi cantly decreased the mineral content of the enamel. All the three remineralizing agents signifi cantly increased the mineral content. Group A (CPP-ACP) showed the highest remineralization than Group B and C but was not statistically signifi cant. Conclusion: Within the limitations of the present study, it can be concluded that bleaching with CP decreases the mineral content of enamel and agents such as CPP-ACP, GSE, and wheat grass help in remineralizing the bleached surface.
