Potential Outcome, Enamel Surface Roughness and Tooth Sensitivity of in Office Bleaching and at Home Bleaching

Abstract

Bleaching has become the treatment of choice for most tooth discolorations. In-office bleaching and at-home bleaching are the most frequently performed vital tooth bleaching techniques. Both of these techniques are proven to improve tooth discoloration, but unwanted effects can also occur, such as tooth sensitivity and increased tooth enamel surface roughness. Tooth sensitivity is a common side effect of bleaching procedures and the effect of bleaching on dental hard tissue is still a matter of controversy. This literature aims to conduct an integrative literature study with scientific evidence related to the potential results, enamel surface roughness, and tooth sensitivity in in-office bleaching and at-home bleaching techniques. Method: Analyzing journals from databases such as Medline (PubMed), Ebsco, Google Scholar, textbooks, and accredited national journals. Conclusion: This review reveals that at-home bleaching has the same potential as in-office bleaching in lightening tooth color. Higher tooth sensitivity was found in in-office bleaching, however in at-home bleaching with 20% carbamide peroxide the tooth sensitivity could be higher. An increase in tooth enamel surface roughness can occur in both techniques, but the at-home bleaching technique is more influential
