A comparative study on efficacy of various disinfectant systems on dental impression surfaces: In vivo study
Journal Title: Journal of Dental Specialities - Year 2018, Vol 6, Issue 2
Abstract
Purpose To evaluate the microbial load on impressions and the efficacy of various disinfectants on reducing microorganisms from the impression surface after disinfectionMaterials and Methods A total of 50 dentulous impressions were made for dentate patients each of age 20 to 50 years using Alginate and Polyvinyl siloxane Impression compound and zinc oxide eugenol were used for edentulous patients each of age 50 to 70 years total of 50 edentulous impressions were made Samples were collected with the help of an 8mm diameter sterile cork borer from each individual impression Alginate ZOE and impression compound had 100 samples each Polyvinyl siloxane had 125 samples Out of 100 samples the first group of the sample was assigned as control n25 the second group of samples n25 were immersed in 2 Glutaraldehyde the third group of samples n25 were sprayed with Dimenol the fourth group of samples n25 were placed in the ultraviolet light chamber For polyvinyl siloxane an additional fifth sample group n25 was subjected to microwave radiation of 650W The viability of microorganisms that can persist after rinsing and disinfecting the impression surface was tested by inoculating in nutrient media The colony forming units were counted and compared with the control group The data were documented and statistically analyzedResults There was a significant difference in the count among the control group and the disinfectant groups Microbial load found on control groups was taken as 100 Alginate samples which were disinfected with 2 Glutaraldehyde Dimenol spray and UV light showed microbial load 31 46 44 respectively Polyvinylsiloxane samples showed microbial load 35 53 48 and 0 with microwave radiation respectively Impression compound samples showed 32 49 49 respectively Zinc oxide eugenol samples with 2 Gluteraldehyde dimenol and UV showed a load of 39 51 51 respectivelyConclusion 2 Glutaraldehyde showed higher efficacy in reducing the microflora compared to Dimenol spray and UV radiation There was complete removal of microorganisms with Microwave radiationKeywords Impression materials Disinfectants Microbial load
