    The objective of this study was to compare the effectiveness of four disinfection techniques in dental impressions with condensation silicone in 2023. Materials and Methods: A total of 50 dental impressions obtained from patients were divided into 5 groups for treatment. Control group: ten impressions using condensation silicone, without disinfection, only immersed in distilled water for 10 minutes. Group 1: ten individual impressions passed through distilled water, then swabbed and immersed in 2% glutaraldehyde for 10 minutes, followed by swabbing and inoculating on agar-agar. Group 2: ten dental impressions passed through distilled water, then immersed in 0.5% sodium hypochlorite, followed by swabbing and inoculating on agar-agar. Group 3: ten dental impressions passed through distilled water, then immersed in 2% chlorhexidine, followed by swabbing and inoculating on agar-agar. Group 4: ten dental impressions passed through distilled water, then exposed to ultraviolet light for 10 minutes, followed by swabbing and inoculating on agar-agar. Results: It was observed that distilled water does not completely eliminate microorganisms, only reducing them, and no significant difference was found (p>0.05). Glutaraldehyde 2% had a p-value = 0.004, showing a significant difference (p<0.05) compared to the control group. Chlorhexidine 2% had a p-value = 0.002, showing a significant difference (p<0.05) compared to the control group. Sodium hypochlorite 0.5% had a p-value = 0.004, showing a significant difference (p<0.05) compared to the control group, while ultraviolet light had a p-value = 0.114, showing no significant difference (p>0.05) compared to the control group. Conclusion: It was concluded that the most effective agent for disinfection of dental impressions with condensation silicone is 2% chlorhexidine immersed for 10 minutes.
