However, immersion is the most reliable method because all surfaces of impression and tray come in contact with disinfectant solution. Since none of the mentioned disinfection protocols have been accepted as a standard gold for disinfecting dental materials and the presence of hazardous microorganism on dental impression can impose detrimental effects, the present study was designed to investigate the disinfection effect of Deconex Solarsept solution, sodium hypochlorite 0.525%, and Epimax on alginate impression material in 5 minutes and 10 minutes. In another study by Ghahramanloo and colleagues, spraying sodium hypochlorite 0.525% could disinfect samples effectively (96.6%) in 10 minutes [9]. In Prac. The efficiency of disinfection methods and their adverse effects on the materials are being evaluated since 19743. Hiraguchi H, Kaketani M, Hirose H, Yoneyama T.

It is the responsibility of the dentist to make appropriatechoice of disinfection method for different impression materials. For each type of susceptibility testing, a standard inoculum of bacteria must be used. It is also tuberculocidal, fungicidal and virucidal for enveloped viruses as well.14,20,22,23 Alcohols are contraindicated for impression disinfection because they can cause surface changes of impressions.3 They are also not suitable for disinfection of denture bases consisting of non-cross linked resins.24, Phenols: Complex phenols are classified as intermediate level disinfectants.

It is recognised that immersion disinfection can have deleterious effects on some proper-ties of the impression materials, for example dimensional accuracy, stability and wettability10-12. Mode of Action and Development of Resistance toDisinfectants, Part 2. Disinfection and sterilization methods are used to achieve disinfection and sterility of the medical and surgical instruments. J Prosth Dent. Studies indicate that the surface of impressions taken out of the mouth is polluted with bacteria [14–17]. [1]Disinfection can be divided into three categories according to their efficacy. According to Table 1, the disinfection action of three mentioned disinfectants showed no significant difference after 5 minutes for Candida albicans and Pseudomonas aeruginosa, however, this difference was significant for Staphylococcus aureus. At low concentration, they cause lysis of rapidly growing e.coli, staphylococci and streptococci. The impression materials were Optosil Comfort and Xantopren VL Plus and the disinfectant solutions were 1% sodium hypochlorite and 2% glutaraldehyde. These materials are supplied as a base and a catalyst and are self-curing. Disinfection is the process of elimination of most pathogenic microorganisms (excluding bacterial spores) on inanimate objects.

This involves cleaning all surfaces of dental instruments to remove blood, microbes, and debris, and to prepare instruments for sterilization or disinfection. Kollu S, Hegde V, Pentapati KC. Efficacy of Chlorhexidine in Reduction of Microbial Contamination in Commercially Available Alginate materials-in-Vitro Study. In this survey, for the first time the antimicrobial effect of Epimax on impression materials was investigated. In this in vitro experimental study, 66 circular samples of alginate impression material were contaminated with Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans fungus. In the present study, all three kinds of disinfectant materials could efficiently eradicate all kinds of microorganisms, but Epimax showed more promising results compared to two other disinfectants.

The results of this study showed that a 0.525% Naocl least affected the cast with regard to compressive strength, surface changes, surface hardness and chemical reactivity.32, The Japan Prosthodontic Society has recommended the alginate impression in either 0.1-1% Naocl solution for 15-30 min or 2-3.5% gluteraldehyde solution for 30-60 minutes. We are committed to sharing findings related to COVID-19 as quickly as possible. The aim of this literature review is to generate an update on the various techniques of impression disinfection along with their mechanism of action and simple guidelines for their usage. J. Prosthet. 926. value Disinfection is the process that eliminates many to all pathogenic microorganisms on inanimate objects except bacterial endospores. 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.

This agent exerts its effect mostly on Pseudomonas aeruginosa since it eradicated 99.27% and 100% of Pseudomonas aeruginosa after 5 and 10 minutes, respectively. The most common chemical disinfectants which are used by dentists are alcohols, aldehydes, chlorine combination, phenols, biguanides, iodide combinations, and ammonium [7]. Author information: (1)Faculty of Medicine and Dentistry, Department of Dentistry, University of … Also it was shown that the disinfection capacity of Deconex can increase from 5 to 10 minutes. Although Epimax represented a significant difference with other disinfectants in 5 and 10 minutes in eradicating Staphylococcus aureus from alginate samples, there was no significant difference in its capacity in eradicating other microorganisms compared to other agents. If it is used in proper concentration and specialized equipment, it can destroy all types of micro-organisms including bacterial and fungal spores, tubercle bacilli and viruses.16 it is a colorless liquid with pungent odour. Various methods of impression disinfection have been described in literature having their own advantages, disadvantages and effects on impression material. The proper criteria for impression disinfection involves: The factors to be considered for any disinfection protocol for dental impression are effectiveness, chemical stability and efficacy of the disinfectant solution. The recommended time and concentration for the effective use of trypsin is 60 minutes and 2%, respectively. Taking this into account, we should make an effort to eliminate most of these microorganisms and reduce the rate of infection transmission in dental laboratories. Eventually, 66 alginate samples were prepared. The most frequently identified microorganisms are Streptococcus species, Staphylococcus species, Escherichia coli species, Actinomyces species, Antitratus species, Pseudomonas species, Enterobacter species, Klebsiella pneumonia, and Candida species [3]. A dental impression is a negative imprint of an oral structure used to produce a positive replica of the structure for use as a permanent record or in the production of a dental restoration or prosthesis. In recent years, with the continuous improvement in the intensification of livestock husbandry and aquaculture, the density of housed animals has increased. It is also called chemo sterilizer. 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. impressions . Appropriate application (time of contact). Introduction. These include use of disinfectant spray, immersion in disinfectant solution, and incorporation of disinfectant in stone at the time of mixing.31 Immersion in 0.525% NaOCl did not cause any changes in dimensional accuracy, surface detail quality and compressive strength.32 Microwave irradiation can also be used for cast disinfection. Rentzia A, Coleman DC, O’Donnell MJ, Dowling AH, O’SullivanM. Low level disinfection possesses narrow antimicrobial activity. Lawrence CA, Carpenter CM, Naylor-Foote AW. Merchant and J. The immersion method is more effective because disinfection of all surfaces of the impression material is guaranteed (Kaul et al., 2012). Impression materials, impression trays, and poured stone cast have been said to be the main source of cross infection between patients and dentists [1]. Journal of Pakistan Dental Association is the (JPDA) the official scientific journal of Pakistan Dental Association (PDA). Cross infection control is very important aspect of patientsafety, Impression disinfection can prevent spread of infectionfrom dental clinic to dental laboratory technician, patients and dental auxiliaries. DOI: https://doi.org/10.25301/JPDA.274.207, Received: 27 July 2018, Accepted: 02 August 2018. / The grown fungus colonies of Candida albicans on SDA were counted after 72 hours. Dentists practicing dentistry encounter potentially harmful microorganisms. In order to avoid the spread of pathogens from patients to patient, patient to health care personnel and health care personnel to patient, it is the duty of the health care policies makers to allocate the appropriate methods of cleaning, disinfection and sterilization for various surfaces and instruments.1 Cleaning is the removal of all foreign material (e.g. 8 Percentage of bacterial growth prevention by different disinfectant agents in 5 and 10 minutes.

Cross-infection control is of prime importance in dental practice but impression disinfection is still a widely neglected aspect. Also, pressure while taking an impression and saliva can alter bacterial adherence capacity. Deconex is an alcohol based disinfectant agent that in this survey could effectively disinfect impression materials. It is published quarterly. There was no significant difference in disinfection capability of the above disinfectants on Candida albicans and Pseudomonas aeruginosa and neither in disinfection ability of Deconex and Sodium Hypochlorite 0.525% on Staphylococcus aureus. Other disinfection methods may also be used such as microwave irradiation, ultraviolet (UV) light radiation, steam autoclaving, ozone and electrolyzed oxidizing water (EOW) disinfection. Most of the studies on impression disinfection focused on the dimen-sional changes and surface details3,10,14,15. Epimax completely prevented the growth of microorganisms in 10 minute (100%). study [20], it was reported that Deconex is quite effective against Pseudomonas aeruginosa and Staphylococcus aureus. 2006; 11(4):147-57. By knowing all the methods and techniques, any dental personnel can make a better choice and get best results for impression disinfection. A. Orsi and V. G.

Except for control samples, all of them were disinfected with sodium hypochlorite 0.525, Deconex, and Epimax by way of spraying. Contrary to immersing, spraying can significantly reduce the amount of distortion [6]. There are two common methods to disinfect dental materials: (1) immersion and (2) spraying [6]. These are bactericidal, mycobactericial and virucidal. Therefore, dental casts should also be disinfected.7 The American Dental Association recommends various methods for cast disinfection. Immersion in NaOCl at concentration of 1:10 (0.525%) is advised for 10 minutes. Sterilization of dental stone cast has shown improved mechanical properties but decreased compressive strength. However, according to its composition, texture, and hydrophilic setting mechanism, this material can easily get contaminated compared to the elastomeric impression materials. Epimax also completely eradicated Staphylococcus aureus with higher rate compared to two other disinfectants. APIC guideline for selection and use of disinfectants.Am J Infect Control; 1996;24(4):313-42. Epimax is a broad spectrum hydrogen peroxide based products. Pseudomonas aeruginosa is a deadly infectious agent that exists epidemically on hospital instrument [18]. 0 J Indian Prosthodont, Rad FH, Ghaffari T, Safavi SH. Clin. 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. One of the drawbacks of the present study is that it was an in vitro experimental study, which is different from clinical and in vivo situations. These are not sporicidal and cause staining of fabrics. In the present survey, 0.525% hypochlorite sodium agent which is common in housework was used. Introduction. Also the American Dental Association (ADA) has advised all dental stuffs to disinfect patients’ impression trays [5]. Disinfection by soaking in chemical materials has been shown to cover all surfaces of impression materials in one time [8], while spraying is not capable of disinfecting all surfaces effectively and also cannot cover all undercuts. In addition, the spread of animal infectious diseases is accelerating, and various animal epidemics have emerged (Wu et al., 2012; Mellata, 2013; Mughini-Gras et al., 2014; Threlfall et al., 2014; Barbosa et al., 2017; Poulsen et al., 2017; Stromberg et al., 2017; Vinayananda et al., 2017). Two methods of disinfection of dental impression materials are commonly used; spray disinfection and immersion disinfection. Method and Materials. Then the mixture was poured into a 5 cc sterile syringe; after the required time for material setting, the impression material was cut off and removed with a number 10 surgical blade from the end part of the syringe to different slices with 2 mm thickness.
