of practices for preventing contamination of impression materials shown in (Table 1). MATERIALS AND METHODS: Crown preparation was done in a dentulous acrylic resin denture base model with six natural teeth embedded into it was made to represent the dentulous maxillary arch. However, most of the dental professionals in private clinics, hospitals, dental schools and prosthetic laboratories are not following the required protocols for impression disinfection.11,12 Keeping in view the above findings, it is of utmost importance to raise the level of awareness in dental professionals involved in any process of handling, transportation, processing and storage of the dental impressions. Trypsin protease, which is able to isolate the microbes from contaminated environments, was used. ). Also it was shown that the disinfection capacity of Deconex can increase from 5 to 10 minutes. 2017:12597. It is also used as prophylactic agent before etching for the placement of restorations.29 Ozonated water can also be used as impression disinfectant. Impression materials, impression trays, and poured stone cast have been said to be the main source of cross infection between patients and dentists [].New researches have shown that 67% of materials sent to dental laboratories are infected by various microorganisms []. This could be due to longer time of exposure of the impression material to the disinfectant by immersion than by spraying. Any compatible disinfectant solution should not cause any alteration on the surface detail reproduction.37, Although some chemical disinfectants cause dimensional changes in impression surface, these changes are not expected to alter the clinical performance. The grown fungus colonies of Candida albicans on SDA were counted after 72 hours. It will also provide knowledge about mechanism of action, concentration of usage along with commercial preparations available of different disinfectants. Gelson Luís Adabo et al investigated the effect of disinfection methods on the dimensional stability of 6 elastomeric materials. The importance of cross-infection control cannot be overemphasized. In one study, while comparing UV rays disinfection with Glutaraldehyde and NaOCl, UV rays exhibited maximum efficacy.36, The factors affecting the efficacy of NaOCl include concentration and life of solution, pH, temperature and contact time with the impression surface. Rutala WA. wearing butyl or nitrile gloves, closed system for solution handling, exhaust ventilation of the places of handling and keeping the temperature of the solution low as it will reduce the airborne concentration of the solution.17, Sodium hypochlorite: It provides intermediate level disinfection and has a broad spectrum antimicrobial activity. Since so many dentists are concerned about viruses such as HIV and HBV, further studies should be conducted to find an effective method to eradicate these kinds of pathogens. Efficacy of Chlorhexidine in Reduction of Microbial Contamination in Commercially Available Alginate materials-in-Vitro Study. Also Saborow Dextrose agar (SDA) medium was used to investigate the presence of Candida albicans fungus. Impression materials were submitted to the following treatments: immersion in 5.25% sodium hypochlorite solution for 10 minutes, immersion in 2% glutaraldehyde solution for 30 minutes, and no immersion (control). %0.525 sodium hypochlorite and Deconex eliminated 97.12% and 95.39% of Staphylococcus aureus, respectively. In an in-vitro study Lu JX et al.11 found no dimension deformation on the Silicone rubber, Irreversible In Prac. Wang J, Wan Q, Chao Y, Chen Y. Therefore, disinfection of impressions should be carried out using specific methods and disinfectant solutions for each type of material. McDonnell G, Russell AD. After 5 minutes, Epimax showed the highest disinfection action on Staphylococcus aureus as it completely eradicated the bacteria. It is a sensitizer of skin and respiratory tract, so special precautions are needed while using it e.g. 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. 2012;23(4):417-21. 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. 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. A self-disinfecting irreversible hydrocolloid impression material mixed with chlorhexidine solution. Both spraying and immersing decrease surface details to the same extent. In order to disinfect all samples except controls, either sodium hypochlorite %0.525,Deconex, or Epimax were used on each sample applying spray method for 10 puffs in 15 seconds. 0 Nassar U(1), Flores-Mir C(1), Heo G(1), Torrealba Y(1). 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]. From total 21 samples, sodium hypochlorite %0.525 was used to disinfect three of them for five minutes and three others for 10 minutes. Three samples were disinfected with Deconex for five minutes and three others for 10 minutes, and three samples were selected for disinfecting with Epimax for five minutes and three others for 10 minutes. 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 antimicrobial effect of spraying and immersing methods was almost equal while mere water rinsing showed no significant disinfection effect [12]. :- river, tanks & lakes. Ferreira FM, Novais VR, Júnior PC, Soares CJ, Neto AJ. In another study, Rueggeberg et al. Muhammad Asif Mushtaq1                                                 BDS, Muhammad Waseem Ullah Khan2                                  BDS, FCPS. 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. Dentists, dental materials, and dental laboratories are exposed to different types of pathogenic microorganisms. Merchant and J. It is also fungicidal but requires more contact time. According to results of the present study, it can be concluded that all three kinds of disinfectant agents effectively disinfected alginate. ( Morton HE.

They are not flammable. For Deconex-Epimax and hypochlorite sodium-Epimax, there is a significant difference in eradicating Staphylococcus aureus ( 2010;10(3):182-9. https://doi.org/10.1007/s13191-010-0040-y, Shambhu HS, Gujjari AK. Also the American Dental Association (ADA) has advised all dental stuffs to disinfect patients’ impression trays [5]. An overview of dental impression disinfection techniques- a literature review. Guiraldo RD, Borsato TT, Berger SB, Lopes MB, Gonini-Jr A,Sinhoreti MA. This study revealed that alginate can be effectively disinfected by three types of disinfecting agents by spraying method, although Epimax showed the highest disinfection action after 10 minutes compared to other agents. Other disinfection methods may also be used such as microwave irradiation, ultraviolet (UV) light radiation, steam autoclaving, ozone and electrolyzed oxidizing water (EOW) disinfection. Table 2: Types of Disinfectants.4,13,14,15. For Candida albicans fungus, the samples were taken from 48 hour Saborosa and Dextrose agar cultures. Different techniques of impression disinfection and other methods of cross-infection control must be a part of undergraduate curriculum of dental  universities and dental technician schools. Spray disinfection and immersion disinfection are the two methods of impression disinfection. 1992;68(1):191-5. https://doi.org/10.1016/0022-3913(92)90303-R, Touyz LZ, Rosen M. Disinfection of alginate impression material using disinfectants as mixing and soak solutions. A double-blind peer review system is followed to ensure a high quality of publications. The present randomized experimental study was carried out with the cooperation of Department of Microbiology the School of Dentistry, of Isfahan University of Medical Sciences aiming at evaluating the disinfection effect of: sodium hypochlorite %0.525 (Chloran, Tehran, Iran), Deconex (Borer chemie, Switzerland), and Epimax (Emad, Isfahan, Iran) on the alginate impression material (Zhermak, Rome, Italy). In order to assure that the samples were kept sterile during preparation, three samples were selected as negative controls (blank) and were incubated on TSB culture for 24 to 48 hours, after which the bacterial growth was examined. study in 1992 [11], the efficacy of eight different disinfectant agents was assessed; among them Sporicidin and 0.525% sodium hypochlorite effectively eradicated Staphylococcus aurous in all samples.

Gypsum casts as a potential source ofmicrobial cross-contamination. J Dent. It can be postulated that the use of a more resistant type of bacteria can explain this difference. Official Journal of the Pakistan Dental Association. 1 impressions . 8.0 Disinfection and Sterilization | Environmental Health and Safety. However, immersion is the most reliable method because all surfaces of impression and tray come in contact with disinfectant solution. These are not sporicidal and cause staining of fabrics. Disinfection – disinfection is a process in which all microbes are removed, except bacterial spores. In this in vitro experimental study, 66 circular samples of alginate impression material were contaminated with Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans fungus. The impressions were put in sterile test tubes separately with 1 cc of microbial suspension each and then incubated at 35°C for one hour. In 2008, Kotsiomiti et al. Hemalatha, R., & Ganapathy, D.

The effect of tray material on change in volume (calculated as after disinfection minus before disinfection) was significant for one impression material; acrylic trays produced the greatest effect. 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. Ghahramanloo et al. 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. However, studies show that among the population, the spreading rate of Staphylococcus aureus to the nasopharynx is only 10% [13]. Sterilization of dental stone cast has shown improved mechanical properties but decreased compressive strength. Kollu S, Hegde V, Pentapati KC. 2018; 9:37. https://doi.org/10.4103/ijpvm.IJPVM_143_16. The most important feature of Epimax is that it does not make bacteria resistant against disinfectant materials and it is highly biocompatible and does not induce any allergic reactions. ). The impression materials were Optosil Comfort and Xantopren VL Plus and the disinfectant solutions were 1% sodium hypochlorite and 2% glutaraldehyde. HOW TO CITE: Mushtaq MA, Khan MWU .

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). 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. 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.

These results are also in accordance with the results of the present study. This disinfection capacity can be increased as time elapses except for Pseudomonas aeruginosa which was eradicated effectively in both 5 minutes and 10 minutes. / For information concerning the proper disposal of all disinfected or sterilized waste, please refer to the Generators’ Guide to Hazardous Material / Waste Management. In another study by Ghahramanloo and colleagues, spraying sodium hypochlorite 0.525% could disinfect samples effectively (96.6%) in 10 minutes [9]. Surface detail reproduction and dimensional accuracy of stone models: influence of disinfectant solutions and alginate impression materials. [1]Disinfection can be divided into three categories according to their efficacy. Disinfection of dental impressions by immersion is considered one of the safest methods of disinfection, since literature states that the porosity of dental impression materials leads to the penetration of microorganisms, which disinfection by spray may not effectively destroy. < When removing an impression from the mouth, the material must be suf… 0 Details of Health givers disinfection practices shown in (Table 2).
