A SYSTEMATIC REVIEW OF THE RISK AND SERENCE OF DENTAL HYPERESTHESIA AFTER A WHITENING PROCEDURE

Аннотация

A systematic review and meta-analysis were conducted to assess the risk and severity of tooth sensitivity after bleaching with and without a desensitizer in adult patients. Discoloration and risk of gum sensitivity were also assessed. A comprehensive MEDLINE search was conducted through PubMed, Scopus, Web of Science, Cochrane Library. Most of the studies had an unclear risk of bias. There were no differences between groups in the risk ratio for MD (hazard ratio = 0.99; 95% confidence interval [CI] = 0.74-1.33); GZ intensity (standardized mean difference [SMD] = 0.04; 95% CI = 0.79-0.70); color change in color units (CPC - 0.04; 95% CI = 0.50-0.42); discoloration in ΔE* (CRR = 0.41 (95% CI = 0.07–0.89) and gingival irritation risk ratio (CRR = 1.05; 95% CI = 0.81–1.36). With the exception of the risk of GBM, which was rated as moderate quality of evidence, all other outcomes were rated as low to very low GBM, discoloration, and risk of gingival irritation were similar between groups, but the quality of the evidence for these outcomes was rated as low or very low, which reduced the level of confidence in these outcomes. The inclusion of desensitizers in the whitening gel did not reduce the risk of HC, and the quality of this evidence was considered moderate. On the other hand, GB intensity, discoloration, and risk of gingival irritation were similar between groups, but the quality of the evidence for these results was rated as low or very low, which reduced the validity of the results.
