Careful wetting or soaking of all surfaces of impressions is very important when using a spray.Ĭontamination dental impressions spray disinfection effectiveness. Disinfection with the aldehyde-based spray resulted in only two contaminated impressions, both in alginate.Īlcohol-based spray disinfection of dental impressions may be less effective than aldehyde spray and full immersion of impressions is recommended. Analysis of post-disinfection growth according to impression and disinfectant found significantly more contaminated PVS impressions with the alcohol-based spray than with the aldehyde spray (x 2 = 5.37, p < 0.05). Post-disinfection contamination was present on six alginate and six PVS impressions but only one polyether impression (x 2 = 1.27, P > 0.05, NSS). The counts were categorized into two groups: no growth or growth present. After incubation, all plates were examined for microbial growth.Ī total of 87 impressions were assessed (alginate = 41 poly-vinyl siloxane (PVS) = 31 polyether = 15). Plates were incubated for 3 days at 37☌ then at room temperature for 3 days. Swabs were transported to the microbiology laboratory in Amies medium and plated onto sheep blood agar within 2 hrs. Impressions were swabbed after removal from the mouth (pre-disinfection) and after spraying (post-disinfection) with either a non-aldehyde alcohol-based disinfectant, Bossklein (Silsden, W Yorks, BD20 0EF, UK) or a glutaraldehyde-based alcohol-free disinfectant, MD520 (Dürr Dental, 74321 Bietigheim-Bissingen, Germany). This study compared the effectiveness of alcohol and aldehyde spray disinfectants on analogue dental impressions in a hospital setting. The gold standard for disinfection of dental impressions is by immersion although spray techniques are also available.
