Effect of etching on bonding of a self‐etch adhesive to dentine affected by amelogenesis imperfecta
Abstract
Aim Dentine affected by amelogenesis imperfecta (AI) is histologically altered due to loss of hypoplastic enamel and becomes hypermineralized. In the present study, we examined the effect of additional acid etching on microtensile bond strength of a self-etch adhesive to AI-affected dentine. Methods Flat coronal dentine obtained from extracted AI-affected and non-carious permanent molars were allocated to two groups: (a) Clearfil SE Bond (control); and (b) Clearfil SE Bond and additional etching with 34% phosphoric acid for 15 seconds. The bonded teeth were sectioned into .8-mm 2 beams for microtensile bond strength testing, and stressed to failure under tension. The bond strength data were analyzed using two-way analysis of variance (dentine type and etching step) and Student-Newman-Keuls multiple comparison test (P Results Both factors, dentine substrate (P Conclusion Additional acid etching does not improve the bond strength of a self-etch adhesive to AI-affected dentine.

“…at this point, this review revealed heterogeneous treat-ment strategies documented in the CR, very few in vitro studies (e.g., Yaman et al. 2014; Epasinghe and Yiu 2018; Massé et al. 2021), a widespread lack of clinical trials on adhesive bonding to structurally altered enamel and dentin, and…”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
