Background: Laboratory bacterial cross-contamination is very high in dentistry, to avoid this disinfection is a necessity. Gypsum products are a medium of cross infection between the dentist and the laboratory personnel. The purpose of this study was to determine, if Chloramine-T is added as a disinfectant in the gypsum type III material, then are there any changes in the setting time and abrasion resistance of the gypsum. Methods: For setting time vicat needle apparatus (Brand- AIMIL Ltd.) was used for two groups one with Chloramine-T (Group-1) and one without Chloramine-T (Group-2) as disinfectant. For abrasion resistance a two body wear test was used, testing was done in two groups one with Chloramine-T (group-3) and one without Chloramine-T (Group-4) as disinfectant. For both the tests, each group had 35 samples. Pre weight and post weight of the samples were recorded for both control and experimental groups to measure abrasion resistance. For setting time the initial setting time was recorded for both the groups. Results: It was discovered that the mean value calculated for setting time was 0.08 seconds more than the control group which is significant statistical value but this difference does not make a significant change while clinically manipulating gypsum as the initial setting time is 4-6 minutes. Also the difference in the mean value was not found as statistically significant for abrasion resistance of type III gypsum product before adding Chloramine-T between the control and experimental group. Conclusions: The physical features of dental stone are unaltered with the addition of Chloramine-T as a disinfected for type III gypsum product and hence it can be utilised for all of its dental applications. Gypsum product added with Chloramine-T as a disinfectant will prevent cross-contamination from occurring and help in maintaining the sanitisation.

This study was conducted to investigate the effect of adding silica nanoparticles on the physicochemical properties, antimicrobial action, and the hardness of dental stone type 4. Dental stone type 4 powder was physically mixed with nanoparticle powder at weight percentages (0, 0.5, 1, and 2 percent). The required amount of powder was added to water according to the manufacturer's instructions. The prepared set materials were subjected to the physicochemical studies; Fourier transmission infrared spectroscopy (FTIR) was taken up to investigate the functional groups and X-ray diffraction (XRD) was used to evaluate the crystallinity. Also, scanning electron microscopy (SEM) was used to examine the morphology of the prepared samples. Agar diffusion test was carried out for the prepared samples against the Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) to test the average growth inhibition zones. Finally, the Vickers surface hardness test was performed for each group using a hardness tester. The adding silica nanoparticles to dental stone type 4 increased the diameter of inhibition zones for the groups in both bacteria significantly ( p < 0.05). The results showed that adding silica nanoparticles to dental stone type 4 increased the diameter of inhibition zones for the groups in both bacteria significantly ( p < 0.0001). There was a significant difference between all groups and the 0% group in both bacteria ( p < 0.0001). Besides, the adding of silica nanoparticles to dental stone type 4 increased the surface hardness significantly ( p = 0.0057) without any effect on physicochemical properties. The 0% and the 0.5% groups had significant differences with the 2% group ( p = 0.0046 and p = 0.0205 respectively). Then, at least 2% silica nanoparticles are needed for a significant increase. Clinical trials are needed to enlarge for dental stone type 4 containing silica nanoparticles in the future.
