Purpose: To evaluate the effects of various beverages on surface roughness and microhardness of PEEK and PEKK polymers.
Methods: Rectangular-shaped PEEK and PEKK polymers were fabricated and examined in the study. The specimens were immersed for 28 days at 37°C in red wine, coffee, and distilled water.
Article Synopsis
- The study investigates the color stability, solubility, and water absorption of PEEK and PEKK materials under different storage conditions using red wine, coffee, and distilled water.
- Baseline color measurements were taken before soaking, and after 28 days, significant differences were found in color change, with PEEK showing higher water sorption than PEKK.
- Overall, PEKK showed better performance in terms of less color change and water absorption, suggesting its potential as a preferable material in CAD/CAM applications.

Background: The esthetic expectations of patients are increasing by the day. That is why it is important to minimize the color changes in the oral cavity in both the temporary and permanent restorations.
Aim: This study was carried out to compare the time-dependent color changes of polished and unpolished temporary crown materials prepared by different methods in various solutions.
Objective: Diabetic patients may have vitamin deficiencies, which are important in the follow-up and complications of diabetes for various reasons. It may be beneficial to include the use of dental prosthesis among the parameters that should be investigated as a cause of vitamin deficiency during the management and follow-up of diabetes mellitus. We aimed to investigate the association between serum vitamin B12, folic acid, 25-hydroxyvitamin D, ferritin, iron, magnesium, and HbA1c levels in diabetic patients with and without removable dental prosthesis and in non-diabetic patients with prosthesis.

Materials And Methods: One hundred twenty-eight polymer-infiltrated specimens (n = 32) for four different computer aided design-computer-aided manufacturing (CAD-CAM) materials, polyether ether ketone (PEEK) (PE), polyether ketone ketone (PEKK) (PK), composite resin nanoceramic (Cerasmart) (CS), and polymer-infiltrated ceramic network (PICN) (VITA ENAMIC) (VE) were milled from CAD-CAM blocks. They were divided into two groups (n = 16) in terms of surface treatments: airborne-particle abraded (AA) or silica-coated (SC) and two subgroups (n = 8) according to adhesive application or no adhesive.
