Potassium iodide (KI) has been reported to minimize the staining caused by silver diamine fluoride (SDF). This in vitro study used quantitative evaluation of color changes and silver and fluoride release to determine the effect of KI on the staining and caries-arresting properties of SDF. Results indicated that KI lost its stain-reducing property over time and reduced the effectiveness of SDF.

When 2 types of composite resin were immersed in coffee or tea after polishing with either aluminum oxide discs or diamond-impregnated spiral wheels, the color stability of all polished specimens was found to be clinically acceptable. The coloring agent had a greater effect on color stability than the polishing technique or type of composite resin, and coffee had a greater effect than tea.

This case report describes esthetic rehabilitation in a 28-year-old patient whose maxillary anterior dentition featured irregular gingival contours, multiple restorations, unsatisfactory tooth shapes, and a single darkened tooth. Esthetic harmony was restored by combining periodontal recontouring with the placement of a lithium disilicate crown on the darkened central incisor and lithium disilicate veneers on the other teeth.

Prevalence of zygomatic air cell defects in a North American population
Daniel P. Turgeon
Rachel Novack
Panoramic images of North American adult patients were examined to determine the prevalence and presenting characteristics of zygomatic air cell defects. The prevalence in the entire sample was 2.1%, and there were no significant differences between prevalence rates based on the sex or age of the patient or the laterality (bilateral vs unilateral) or appearance (multilocular vs unilocular) of the lesion.

This in vitro study assessed the color stability of resins used for temporary prostheses. Specimens of self-curing acrylic resin, heat-curing acrylic resin (polymerized with either a pressure-curing or a flasking technique), and CAD/CAM polymethyl methacrylate resin were immersed for up to 28 days in cola, coffee, tea, or turmeric solution. The turmeric solution showed the greatest coloring ability, and the CAD/CAM specimens had the greatest color stability.
