Notes.

^aDental impressions of control groups were kept in air (A), water (W) or wet environment (WE). NR: Dental impressions of control groups were not reported to be kept in air, water or wet environment.

^bEffects of disinfection on the surface properties of dental impressions are indicated as follows: S, significant difference was found when compared to control group; NS, no significant difference; NR, not reported.
