It is appropriate to use NaClO at 1 and 5.25% concentrations for impression disinfection. Although NaClO is an effective disinfectant even at low concentrations, microorganism growth was not observed at 5.25% concentration. To construct a new maxillary prosthesis with palatal lift, preliminary impression was made with irreversible hydrocolloid (Jeltrate, Alginate, Fast set. Simple rinsing of the impressions in sterile water reduced the number of microorganisms but did not decontaminate the impressions.Ĭonclusion Washing with water alone is insufficient for measured disinfection. the pontics require to be blocked out with wax. Stir water and powder with spatula until all powder has been moistened. Alginate impression materials are easy to use, less expensive, with quick setting time. Place three level scoops of powder in water. The control group with no treatment and the water and flushing group had a significantly higher bacterial load compared to the other disinfectant-treated groups in terms of bacterial load, and no significant difference has been observed between the disinfectant solutions ( p < 0.05). Maxillary Alginate Impressions Maxillary Clinician Stands to the Side of Patient Maxillary Trays Adhesive Application Mixing Technique for the Maxillary Place water in bowl first. Results All of the disinfectant solutions tested were effective in the disinfection of the impression materials examined. The differences were considered statistically significant when p < 0.05. The data obtained were statistically evaluated by using analysis of variance and post-hoc tests. Streptococcus mutans, Staphylococcus aureus, Escherichia coli, Candida albicans were used as control strains. After samples were vortexed in 3-mL physiological saline, 1-mL volume were inoculated onto brain heart infusion agar and cultured at 37☌ for 72 hours to determine the number of colony-forming units/mL. Methods Samples obtained from alginate impressions taken from eight pediatric patients selected in accordance with the inclusion criteria with a size of 1 × 1 cm were subjected to five different disinfection protocols. Alginate is one of the most frequently used dental materials and alginate impression is a simple, cost-effective, and indispensable part of dental practice. This course meets the Dental Board of Californias requirements for 2 units. The aim of this study is to evaluate the antimicrobial activity of 1 and 5.25% sodium hypochlorite (NaClO) and zeta 7 solution, a commercial disinfectant, on alginate and to compare it washing with distilled water. materials, including a thorough review of alginate impression-taking along. Objective The impression materials are contaminated with pathogenic microorganisms carried by saliva and blood in the mouth. Buy Article Permissions and Reprints Abstract
