“…They are considered the most common diseases that affect humans worldwide if they are untreated (3) . On the other hand, there is an increase in the prevalence of root caries associated with gingival recessions (4) . The most likely affected teeth by carriers and periodontal diseases more than other teeth are the abutment teeth.…”

The control of oral hygiene is of great importance, particularly in dental work, to prevent caries caused by bacteria. One method to inhibit bacterial growth is usually by using fluoridated dental materials. The objectives are to assess the effect of sodium fluoride powder (NaF) inclusion with different concentrations on the surface roughness and hardness of heat-cured acrylic resins. A total of forty disc-shaped samples with a diameter of (12±0.1) mm and a thickness of (2±0.1) mm have been fabricated from heat cure acrylic resin. They were grouped into four subgroups according to different concentrations of NaF with 10 specimens for each group. Sodium fluoride powder (NaF) was incorporated into the monomer in concentrations of 0% (control group), 1%, 3%, and 5%. Then mixing was done with polymer according to manufacturer instructions and the conventional flasking, and packing procedures were used. Finally, the specimens are subjected to hardness and surface roughness tests. The results of this study revealed that the lowest mean value surface roughness (Ra) was with the (5%) group of NaF (7828). While, for the surface hardness test, the group (5%) of Naf showed the highest mean value among their subgroups (82.30). According to the results of the current study, sodium fluoride powder (NaF) has a positive effect on both the surface roughness and hardness of acrylic resin.

Aim: To determine the enamel solubility and depth of demineralization with laser bleaching and impact of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) when applied prior to and after laser bleaching. Materials and methods:The 40 specimens obtained from 10 human premolars were treated in accordance with manufacturer protocols; laser bleaching was performed using Opalescence Boost Gel (40% hydrogen peroxide) followed by laser activation using 36 mW/660 nm diode laser applied for 4 minutes at an energy fluence of 8.6 J/cm 2 . The study consisted of four experimental groups are as follows: Specimens were, thereafter, subjected to cariogenic challenge and further evaluated for enamel solubility by measuring the loss of Ca 2+ ions and the depth of demineralization using polarized light microscopy.Results: Group 4 exhibited least enamel solubility and depth of demineralization (p < 0.0001) followed by groups 3, 2 and maximum by group 1. Conclusion:Post-laser bleaching application of CPP-ACP followed by a short burst of laser can provide exceptional resistance to enamel solubility (demineralization).
