White and brown opacities due to fluorosis have always been a concern for esthetics. In our study, resin infiltration technique with tailored etching times and increased infiltration time exhibited best immediate esthetic improvement for nonpitted fluorotic opacities and stains. These esthetic outcomes reaffirm the applicability of RI technique for nonpitted fluorosis, which was originally advocated only for white spot lesions due to early caries. This will in turn help the dentists to plan the esthetic management of nonpitted fluorosis in a micro-invasive manner.

“…Regarding DF, 8 of the selected studies assessed the bleaching of the affected teeth, 9 analyzed the effects of enamel microabrasion, 4 evaluated the effect of a combined treatment (tooth bleaching and enamel microabrasion) and Gugnani et al used a resin infiltrant. Gupta et al and Mehta et al studied the effect of oral administration of calcium and vitamins in reducing lesion size whereas Hasanuddin et al applied fissure sealants to molars with DF.…”

Introduction Defects in the maturation stage of amelogenesis result in a normal volume of enamel but insufficient mineralization, called hypomineralization. Molar‐incisor hypomineralization (MIH), amelogenesis imperfecta and dental fluorosis (DF) are examples of such defects. Objective To evaluate the effectiveness of the treatments applied to the different forms of dental hypomineralization. Materials and Methods PubMed, Scopus, Cochrane Library, Web of Science, and Embase were screened. The research was limited to studies published in English, Spanish, and Portuguese, until May 30, 2018. The research question was formulated following the Population, Intervention, Comparison, Outcome strategy. The quality of the methodology of each article was evaluated employing the Cochrane Handbook for Systematic Reviews. Results From the initial research, 7895 references were obtained, of which 33 were included in the systematic review. The following treatments were reported: desensitizing and remineralizing products, resin infiltration, restorations, fissure sealants, tooth bleaching, enamel microabrasion and calcium, and vitamins supplements. Conclusions Although the results are suggestive, there is a clear need for a greater uniformity of the methodologies, thus allowing for the development of clinical guidelines. Nevertheless, it was possible to identify several effective treatments for teeth with MIH (arginine pastes or fluoride varnishes) and DF (tooth bleaching and/or enamel microabrasion). Clinical Significance Because MIH, amelogenesis imperfecta, and DF are commonly seen in dental daily practice, it is extremely important to analyze the literature regarding its treatment.

“…The bleaching effect is achieved due to oxidative action of peroxides and its sub-products on the organic matrix of the tooth tissues modifying its optical properties (6,7). Despite the high success rates observed for both in-office and athome bleaching procedures (4,5), using oxidative agents are unable to solve aesthetic alterations of teeth when the discoloration is intrinsic in the enamel due to fluorosis staining and other enamel hypoplasia, or white lesion spot caused by dental caries (8,9).…”

Impact of Microabrasion on the Effectiveness of Tooth Bleaching

2017

The aim of the present study was to evaluate the effect of prior microabrasion on the teeth color change and tooth bleaching effectiveness. Eight sound molars were mesiodistally sectioned and the halves were randomly allocated to receive enamel microabrasion or non-abrasion (control) in one of surfaces (buccal or lingual), while the remaining surface received the other treatment. The tooth color on baseline was evaluated by spectrophotometer (CieL*a*b system). After the microabrasion procedure, the tooth color was measured again. Following, the specimens were bleached with 35% hydrogen peroxide for two sessions with one-week interval. The color was re-evaluated 7 days after each section and 30 days after the second session. The effect of enamel microabrasion on color changes was evaluated by paired T-test. Deltas L*, a*, b*, and E were calculated and data submitted to 2-way repeated measure ANOVA followed by Tukey`s test. Paired T-test was also used to assess possible differences on the ultimate color achieved after tooth bleaching. Enamel microabrasion reduced the lightness and increased the redness of specimens. Specimens that received microabrasion presented higher values of ∆L* than control after each bleaching procedure; and higher ∆a* after the 2 nd bleaching session. However, the prior enamel microabrasion did not affect the ultimate values of color parameters. Despite enamel microabrasion have modified the tooth color, this procedure did not affect the ultimate results achieved with tooth bleaching using a high-concentrated hydrogen peroxide.
