Effect of Denture Cleansers and Surface Treatments on the Color Stability, Gloss, and Wettability
Now online in the Journal of Prosthodontics, a report on the impact of surface treatments and chemical denture cleansers on properties of CAD/CAM denture bases, co-authored by ACP members Suonds Alareifi BDS, MSD, Chao-Chieh Yang DDS, MSD, FACP, and Wei-Shao Lin DDS, MBA, MSAI, PhD, FACP.
This study evaluated how surface treatment (protective glaze layer vs. polishing only) and three different chemical denture cleansing solutions, along with distilled water as a negative control, affect changes in surface color, gloss, and wettability of various denture base materials.
Specimens were fabricated in three denture base materials (compression-molded, 3D-printed, and milled resins; n = 80 each) and assigned to polish-only or protective-coated (Optiglaze) subgroups. Then, specimens were immersed in one of four cleaning solutions: Polident (alkaline peroxide), Val-Clean (potassium caroate), Renew (alkaline hypochlorite), or distilled water (control group).
Color stability was evaluated using a spectrophotometer with the CIEDE2000 (ΔE00) formula. Surface gloss was measured with a gloss meter, and wettability was assessed by static contact angle using an optical tensiometer.
Renew produced the highest mean ΔE00 (3.90 ± 0.33), exceeding distilled water (1.76 ± 0.33), Polident (0.92 ± 0.80), and Val-Clean (0.78 ± 0.56). Using the acceptability threshold (AT) of ΔE00 = 1.8, all Polident and Val-Clean groups remained acceptable for milled and 3D-printed material. In contrast, compression-molded materials exhibited greater color instability. Polished surfaces generally retained gloss better than Optiglaze‑coated surfaces, and Optiglaze did not consistently mitigate changes in color, gloss, or wettability. Polident or Val-Clean on polished surfaces best preserved color, gloss, and wettability.
