Comparison of the Resistance of Bond Strength of Cemented Fiberglass Posts in Different Root Thirds with and without Silanization: An Study.

Aim: To compare the application of silane in the bond strength of fiberglass posts in different thirds of the cemented root with a self-adhesive system in an study.

Materials And Methods: Freshly extracted teeth were collected, which had indication of extraction for periodontal or orthodontic reasons. The study evaluated = 42 specimens that were divided into two large groups: I (control, without silane) and II (with silane); the resistance to adhesion in the respective thirds of the root (cervical, middle, and apical) was also evaluated.

Remineralizing Effect of Casein Phosphopeptide-Amorphous Calcium Phosphate and Sodium Fluoride on Artificial Tooth Enamel Erosion: An Study.

Aim: To compare the remineralizing effect of toothpastes with casein phosphopeptide-amorphous calcium phosphate (FPC-FCA) and sodium fluoride on the artificial erosion of tooth enamel.

Materials And Methods: For the first phase of artificial erosion, group I was considered as the control group without treatment or erosion. For groups II and IV, the drink was used (Coca-Cola®), for groups III and V, the drink (Inca-Kola®), and the four groups were demineralized four times a day (every 3 hours for 2 minutes) for 5 days.
