    The objective was to compare the dimensional changes of two irreversible hydrocolloids commonly used in dental practice, according to the time elapsed after the impression. Methodology: Two irreversible hydrocolloids, Alginelle and Hygedent, were used to take 27 impressions on an acrylic master model. A reference point was chosen, measuring the transverse distance (intermolar distance), which was also measured in the dental impressions at different time intervals: immediately after the impression, and at 60 and 120 minutes. All data were recorded in the data collection form. Results: The dimensional change of the Alginelle hydrocolloid was 0.35 mm immediately after the impression, 0.42 mm at 60 minutes, and 0.47 mm at 120 minutes. The dimensional change of the Hygedent hydrocolloid was 0.48 mm immediately after the impression, 0.66 mm at 60 minutes, and 0.67 mm at 120 minutes. Conclusion: No discrepancies were found in the dimensional changes of the two commonly used irreversible hydrocolloids in dental practice according to the time elapsed after the impression.
