Due to a publishing error the article: “The effect of cooling procedures on monomer elution from heat-cured polymethyl methacrylate denture base materials”, published at Journal of Applied Oral Science 2022;30:e20220161 was printed with the following error:
Where it reads:
Figure 1. The heat-cured denture base materials used in the study.
* According to the manufacturers’ information. MMA: Methyl methacrylate, PMMA: Polymethyl methacrylate, BPO: Benzoyl peroxide, HQ: Hydroquinone, EGDMA: Ethyleneglycol dimethacrylate, BDMA: Tetramethylene dimethacrylate
It should read:

* Means and standand deviations (in parentheses).Superscript letters show mean values with insignificant differences within each material group (lower case) and between material groups per treatment (upper case). LoQ: Lower limit of quantitation (5.90 ppm), LoD: Limit of detection (1.95 ppm). Bold characters show the values obtained using the cooling modes suggested by the manufacturers.
