Objective The aim of this article is to describe an easy technique for managing small superfi cial defects in light to medium fl uorosis. Method and materials The proposed technique is based on a selective abrasion of the superfi cial enamel and a recreation of the superfi cial macro and micro morphology. The aesthetic appearance can be enhanced by power or home bleaching. Results The presented technique can manage enamel defects which are confi ned in the most external enamel surface with satisfying aesthetic results. Conclusions This conservative approach may be considered an interesting alternative to more invasive prosthetic techniques based on composite reconstructions or ceramic veneers, minimising invasivity, chairside time and costs for patients.

The aims of this study were, first, to measure shrinkage induced by different methods of pulse‐delay light curing and, second, to verify their influence on the marginal adaptation of class V restorations in enamel and dentin. Eight groups, comprising seven groups (n = 6) with different pulse‐delay parameters and a control group, were compared for dynamic linear displacement and force by using a fine hybrid composite. Based on these results, the pulse‐delay curing procedure with the lowest shrinkage force was chosen and tested against the control group with respect to marginal adaptation in class V restorations (n = 8) before and after simultaneous thermal and mechanical loading. Statistically significant differences between groups were found for both shrinkage properties tested, with one pulse‐delay group giving the lowest overall shrinkage values. However, the percentages of ‘continuous margin’ of this group, and of the control before and after loading, were not significantly different in dentin, whereas a significantly lower percentage of ‘continuous margin’ was detected in the pulse‐delay group in enamel after loading.

This work suggests that a 0.1-mm-thick layer of opaque porcelain in the Pd-Cu-Ga alloys studied, did not reliably reproduce the color of porcelain.
