Rentzia A, Coleman DC, O’Donnell MJ, Dowling AH, O’SullivanM. J Dent. Infection control: the role of disinfectionand sterilization. Some impression materials, like alginate which is commonly used in dentistry [9], absorb water and distort when they are immersed in disinfectant materials [10] due to their hydrophilic properties. Westerholm [11] and Rueggeberg [12] and colleagues also showed that spraying sodium hypochlorite can effectively disinfect the impression materials. The effectiveness of microwave ovens for different sterilization and disinfection purposes should be tested and demonstrated as test conditions affect the results (e.g., presence of water, microwave power). Disinfection Techniques: Disinfection solutions: The details are given in Table 2.4,13,14,15, Glutaraldehyde: It is a high level disinfectant and is available in neutral, alkaline and acidic forms.5 It is a broad spectrum chemical agent with fast killing capability. Dentures are being disinfected with microwaves and are found better disinfected than Naocl. These are also known as protoplasmic poisons. Chemicals used in disinfection are called disinfectants. Microbiol. Table 3 displays bacterial disinfection ability of disinfectants in preventing microorganisms growth. 1997; 78(3): 245-9. https://doi.org/10.1016/S0022-3913(97)70021-0, Samra RK, Bhide SV. Personal protective equipment: Protective eye wear, masks and gloves when handling a contaminated impression until it has been disinfected. Alginate materials prepared with a method that produces less porosity may have improved properties such as recovery from deformation, strain in compression, compressive strength, surface detail reproduction, and dimensional stability (Hamilton et al., 2010). Cross-infection control is of prime importance in dental practice but impression disinfection is still a widely neglected aspect. A study on the effect on surface detail reproduction of alginate impressions disinfected with sodium hypochlorite and ultraviolet light-An in Vitro study. These are mainly used as antiseptics rather than disinfectants. This disinfectant agent could efficiently prevent microorganisms' growth and disinfect the impression materials. Objectives: The objective of this systematic review and meta-analysis study was to identify the different disinfection methods and materials and the existing evidence on their effect on properties of the different impression materials. According to results of the present study, it can be concluded that all three kinds of disinfectant agents effectively disinfected alginate. The knowledge of the best effective methods for disinfecting specific impression material was assessed. These are bactericidal, mycobactericial and virucidal. Other disinfection methods may also be used such as microwave irradiation, ultraviolet (UV) light radiation, steam autoclaving, ozone and electrolyzed oxidizing water (EOW) disinfection. Method and Materials. The disinfection capacity of different agents can be increased as time elapses except for Pseudomonas aeruginosa which was eradicated completely in both 5 and 10 minutes. By knowing all the methods and techniques, any dental personnel can make a better choice and get best results for impression disinfection. J Occup Health.

Effect of disinfection on dental impression materials is con-troversial. Int J Pharm Sci Res;2016;7(8):661-64. This could be due to longer time of exposure of the impression material to the disinfectant by immersion than by spraying. In some studies, it has been declared that washing the impression materials with tap water only removes 40% of bacteria; however, some studies reported that it has the capacity to reduce 90%, microorganisms [6]. Disinfection and sterilization methods are used to achieve disinfection and sterility of the medical and surgical instruments. Impression material is packaged several ways for preference of use: tubes of paste, cartridge, or putty system (Figures 22-10 and 22-11). Except for control samples, all of them were disinfected with sodium hypochlorite 0.525, Deconex, and Epimax by way of spraying. chlorhexidine, NaOCl, H2O2. [1]Disinfection can be divided into three categories according to their efficacy. Table 2: Types of Disinfectants.4,13,14,15.

We are committed to sharing findings related to COVID-19 as quickly as possible. The suspensions of 0 Its chemical formula is O3.It is less stable than O2 in lower atmosphere.3 It has antimicrobial, antihypoxic, analgesic and immunostimulatory activities.28 It is used for disinfection of water lines, oral cavity and dentures. 2009;17(6):565-9. Leung RL, Schonfeld SE. After washing the samples with sterile distilled water for 30 seconds, they were put in trypsin 2% solution for 60 minutes. (Table 1).3,4,5 Dental impressions are categorized under semi-critical objects in dental practice and require high level disinfection or sterilization.6 Sterilization in an autoclave will compromise the dimensional accuracy of the impression hence it is not feasible.7 Until 1991, the recommended procedure for disinfection of impression was rinsing under running water with which only 40% of bacteria, viruses and fungi were removed and potential for transmission of microorganisms remains there.3,8,9 In recent times, a pre wash of the impression with running water is advocated first to cast off all particles, blood and saliva prior to active disinfection procedure.10 Disinfection of dental impression should be a routine procedure in the dental office and dental laboratory. The need to use a natural alternative for disinfecting dental impression materials, which should be biocompatible and effective, led us to evaluate the efficacy of Aloe vera as a disinfectant by immersion and spray method on alginate impression material and its effect on the dimensional stability of the resultant gypsum cast. The International Dental Federation (IDF) insists on disinfecting all impressions taken from patients before sending them to laboratories [4]. The statistical analysis shows that there are significant differences in the mechanical properties of the three alginate impression materials, the two mixing methods and the disinfectant.
