. 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 impressions were put in sterile test tubes separately with 1 cc of microbial suspension each and then incubated at 35°C for one hour. This involves cleaning all surfaces of dental instruments to remove blood, microbes, and debris, and to prepare instruments for sterilization or disinfection. 1 The aim of this study was to investigate the effect of three different types of disinfectant agents on alginate impression material after 5 and 10 minutes. Author information: (1)Faculty of Medicine and Dentistry, Department of Dentistry, University of … Results. This is why, chemical disinfection is considered the most harmless form of impression disinfecion.2% gluteraldehyde had exhibited more dimensional changes than 5.25% Naocl in immersion disinfection procedure.38, The American Dental Association’s revised guidelines recommend chemical agents that are virucidal, bactericidal and sporicidal. 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.

Objective: This study evaluated the effect of chemical disinfection and microwave irradiation on the surface hardness and roughness of two commercially available hard relining materials (Ufi Gel hard, GC Kooliner) and one denture base resin (Trevalon).Materials and Methods: A total of 72 specimens (n = 24) were divided into four groups. These results are also in accordance with the results of the present study. [1]Disinfection can be divided into three categories according to their efficacy. J Indian Prosthodont Soc. Rutala WA, Weber DJ. Journal of Pakistan Dental Association is the (JPDA) the official scientific journal of Pakistan Dental Association (PDA). In order to enhance the knowledge and improve the behavior of dental health care workers about impression disinfection, a structured literature (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. It is published quarterly. 2012; 34(5):292-9. https://doi.org/10.1136/inp.e2741, Lepe X, Johnson GH. It is bactericidal, virucidal and mycobacteriostatic. 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. A study on the effect on surface detail reproduction of alginate impressions disinfected with sodium hypochlorite and ultraviolet light-An in Vitro study. The suspensions of Drying:- 4/5ths of weight of bacterial cell consist of water and hence drying has a deleterious effect on many bacteria.

Disinfection and sterilization methods are used to achieve   disinfection and sterility of the medical and surgical instruments. In an in-vitro study Lu JX et al.11 found no dimension deformation on the Silicone rubber, Irreversible 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. 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. Intermediate level disinfection involves destruction of microorganisms like tubercle bacilli but not able to kill spore. Elastomeric impression materials have an elastic or rubber-like quality after setting. It is also used as prophylactic agent before etching for the placement of restorations.29 Ozonated water can also be used as impression disinfectant. In another study, Rueggeberg et al. Guiraldo RD, Borsato TT, Berger SB, Lopes MB, Gonini-Jr A,Sinhoreti MA. 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). Kollu S, Hegde V, Pentapati KC. 2016;44(5):e1-6. did a PubMed search between 1980 and 2005 on the effect of chemical disinfection, by immersions or spraying, on the impression’s dimensional changes. Impression can also be immersed in chlorhexidine solution and it causes effective disinfection.25 According to one study, 1.0 g/L chlorhexidine solution can be used to produce self-disinfecting alginate impression material for clinical use. and We are committed to sharing findings related to COVID-19 as quickly as possible. 2010;10(3):182-9. https://doi.org/10.1007/s13191-010-0040-y, Shambhu HS, Gujjari AK. Comparison of disinfectant agents and control group in 5 minutes and 1 dilution. 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. These are also known as protoplasmic poisons. value J. But immersion is not the method of choice for hydrocolloids material as they are extremely hydrophilic.3,34, In 1996, the American Dental Association council on dental materials endorsed immersion for polysulphide and addition silicone impression material whereas spraying with chlorine compound was advocated for disinfection of polyether impression material for 2-3 min.35 UV rays can be used for disinfection of water supplies, laboratory equipment, dental headpieces, dental impression and implants.

They have irritating effect on mucous membrane.20,21  Organic material present on any surface can lead to neutralization of disinfectant capability of iodine. Review articles are excluded from this waiver policy. They concluded that the use of 0.525% sodium hypochlorite spray on the surface of alginate effectively disinfect 96.6% of the samples [9]. By knowing all the methods and techniques, any dental personnel can make a better choice and get best results for impression disinfection. exposure to UV light, steam autoclave, ethylene oxide gas autoclave, and radiofrequency flow discharge etc.3. These dental casts can be a medium of cross infection between patients and dental health care workers. chlorhexidine, NaOCl, H2O2. Also Deconex showed significantly higher disinfectant action in removing Staphylococcus aureus compared to 0.525% hypochlorite sodium. :- river, tanks & lakes. Sterilization of dental stone cast has shown improved mechanical properties but decreased compressive strength. Sunlight:- Active germicidal effect due to the combined effect of U.V and heat rays. 8.0 Disinfection and Sterilization | Environmental Health and Safety. The aim of this study was to investigate the effect of three different types of disinfectant agents on alginate impression material after 5 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. Most of the studies on impression disinfection focused on the dimen-sional changes and surface details3,10,14,15. 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). Recommendations for hygiene in dental practice including treatment of infectious patients,”, Council Ondt, “Council on prosthetic services and dental labaratory relation. 1 Alginate is one of the most widely used dental impression materials due to its ease of mixing, the flexibility of the set impression, its accuracy when properly handled, and low cost. Other disinfection methods may also be used such as microwave irradiation, ultraviolet (UV) light radiation, steam autoclaving, ozone and electrolyzed oxidizing water (EOW) disinfection. According to one study, aqueous ozone is more biocompatible than other disinfectant solutions e.g. Lawrence CA, Carpenter CM, Naylor-Foote AW. Settings and Design:In vivo - comparative study. Sign up here as a reviewer to help fast-track new submissions. 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. These are mainly used as antiseptics rather than disinfectants. Dimensional stability of dental impressions after immersion disinfection S. Pamela Herrera, MS, DDS,Virginia A. 5 J Occup Health. In Hoseini et al. < Medical surfaces can also be disinfected with isopropyl alcohol. Hemalatha, R., & Ganapathy, D. Disinfection of dental impressionA current overview. These are bactericidal, mycobactericial and virucidal. study [20], it was reported that Deconex is quite effective against Pseudomonas aeruginosa and Staphylococcus aureus. According to Fahimeh et al, the compatibility of disinfectant solution with impression material should be assessed prior to disinfection procedure. 4 found that spraying disinfectants on alginate does not cause dimensional distortion in poured stone casts compared to casts from water-rinsed controls. 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. Dent. Rev. However, studies show that among the population, the spreading rate of Staphylococcus aureus to the nasopharynx is only 10% [13]. 2012, Article ID 695151, 5 pages, 2012. https://doi.org/10.5402/2012/695151, 1Dental Implant Research Center, School of Dentistry, Isfahan University of Medical sciences, 81746-73461 Isfahan, Iran, 2Department of Prosthodontic, Torabinezhad Center Research, Dental School, University of Medical Sciences, 81746-73461 Isfahan, Iran, 3Department of Microbiology, School of Medicine, Isfahan University of Medical Sciences, 81746-73461 Isfahan, Iran. Dentists practicing dentistry encounter potentially harmful microorganisms. 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. APIC guideline for selection and use of disinfectants.Am J Infect Control; 1996;24(4):313-42. Eventually, 66 alginate samples were prepared. Two factors are fundamental: 1) the effectiveness of the disinfection process, and 2) the effect of treatment on the impression and thereby on … Preliminary investigation of a method for disinfection of dental impressions. Ferreira FM, Novais VR, Júnior PC, Soares CJ, Neto AJ. It is the responsibility of the dentist to make appropriatechoice of disinfection method for different impression materials. 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. 1 Dentists, dental materials, and dental laboratories are exposed to different types of pathogenic microorganisms. Yüzbasioglu E, Saraç D, Canbaz S, Saraç YS, Cengiz S. A surveyof cross-infection control procedures: knowledge and attitudes of Turkish dentists.

Assistant Professor, Department of Prosthodontics, Punjab Dental Hospital/de’Montmorency College of dentistry. Objective This study investigated the effect of a commonly used immersion disinfectant upon three different impression materials and any subsequent effects on … This disinfection capacity can be increased as time elapses except for Pseudomonas aeruginosa which was eradicated effectively in both 5 minutes and 10 minutes. Dental impressions can act as vehicle for various types of micro-organisms E.g. 2006; 95(6):462-8. https://doi.org/10.1016/j.prosdent.2006.03.019, Maillard JY, McDonnell G. Selection and use of disinfectants. 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. 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.

A self-disinfecting irreversible hydrocolloid impression material mixed with chlorhexidine solution. Copyright © 2012 Hamid Badrian et al. According to results of the present study, it can be concluded that all three kinds of disinfectant agents effectively disinfected alginate. Methods of disinfection of alginate impression material and its effect on its dimensional stability Although at present, in dentistry, many different types of disinfectants are available, none of them are universally acceptable as mentioned earlier. Except for control samples, all of them were disinfected with sodium hypochlorite 0.525, Deconex, and Epimax by way of spraying. In recent years, with the continuous improvement in the intensification of livestock husbandry and aquaculture, the density of housed animals has increased. Hamid Badrian, Ehsan Ghasemi, Navid Khalighinejad, Nafiseh Hosseini, "The Effect of Three Different Disinfection Materials on Alginate Impression by Spray Method", International Scholarly Research Notices, vol. 5 Ideally not recommended for impression disinfection as simple phenols are low level disinfectants.They are incompatible with latex, acrylic, rubber and cause acute toxicity as well.3,4, Chlorhexidine: It is an intermediate level disinfectant and antiseptic. 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. Takigawa T, Endo Y. Ethyl alcohol is more potent in bactericidal than bacteriostatic activity. In vitro evaluation of dimensional stability of alginate impressions after disinfection by spray and immersion methods. Table 2 illustrate the bacterial disinfection capability of the three above-mentioned disinfectants after 10 minutes.

Table 3 displays bacterial disinfection ability of disinfectants in preventing microorganisms growth. Nassar U(1), Flores-Mir C(1), Heo G(1), Torrealba Y(1). Elastomeric Impression Materials. For each type of susceptibility testing, a standard inoculum of bacteria must be used. Clin Infect Dis; 2004; 39(5):702-9. Addition or condensation silicone impression materials can be sterilized in steam autoclave without remarkable changes in dimensional accuracy.3, Corresponding author: “Dr. 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. Gelson Luís Adabo et al investigated the effect of disinfection methods on the dimensional stability of 6 elastomeric materials. The impression materials were Optosil Comfort and Xantopren VL Plus and the disinfectant solutions were 1% sodium hypochlorite and 2% glutaraldehyde. Aim: The aim of the study was to investigate the effect of disinfection and steam autoclaving on the elastic recovery of three different elastomeric impression materials. 2012-01-01 00:00:00 The Centers for Disease Control and Prevention (CDC), in its infection control guidelines, indicated that dental impressions are potential sources of … Disinfection – disinfection is a process in which all microbes are removed, except bacterial spores. 926. However, according to its composition, texture, and hydrophilic setting mechanism, this material can easily get contaminated compared to the elastomeric impression materials. 0 J. Prosthet. In Westerholm study, it was showed that Sodium hypochlorite can absolutely (99.99%) prevent the growth of Staphylococcus aureus [11], and these results are in agreement with the results of the present study as this material eradicated 97.12% and 98.84% of Staphylococcus aureus after 5 and 10 minutes, respectively. The relationship of concentration and germicidalefficiency of ethyl alcohol. Disinfection and Sterilization in Health CareFacilities: What Clinicians Need to Know? blood, saliva, debris) from objects while decontamination is the removal of pathogenic micro-organisms from objects. The knowledge of the best effective methods for disinfecting specific impression material was assessed. Various methods of impression disinfection have been described in literature having their own advantages, disadvantages and effects on impression material. Statistical Mann-Whitney test was used for data analysis (α = 0.05). The International Dental Federation (IDF) insists on disinfecting all impressions taken from patients before sending them to laboratories [4]. Two methods of disinfection of dental impression materials are commonly used; spray disinfection and immersion disinfection. Impression materials, impression trays, and poured stone cast have been said to be the main source of cross infection between patients and dentists [1]. For Deconex-Epimax and hypochlorite sodium-Epimax, there is a significant difference in eradicating Staphylococcus aureus ( Disinfection with 2% glutaraldehyde solution showed a slight expanding effect on the dimensional stability of the hydrophilic silicone rubber impression materials (less than 0.03%). The importance of cross-infection control cannot be overemphasized. It was observed that Epimax is more efficient in eradicating Staphylococcus aureus compared to two others disinfectant agents. 2018]. ). 2017:12597. Using a Pasteur pipet bent with heat at 90 degrees, the samples were spread on cultures. Immersion in NaOCl at concentration of 1:10 (0.525%) is advised for 10 minutes. The purpose of this Guidance Document for Disinfectants and Sterilization Methods is to assist lab personnel in their decisions involving the judicious selection and proper use of specific disinfectants and sterilization methods.

An appropriate mixture of water and alginate powder was prepared in a bowl with a sterile spatula according to the manufacturers' instructions. 0 Thus, the disinfection of the livestock and poultry houses has become … Candida causes common opportunistic infections known as oral candidiasis found in patients with immune deficiency [19]. Various methods of impression disinfection have been described in literature having their own advantages, disadvantages and effects on impression material. Egusa and colleagues in 2008 showed that alginate impressions taken from patients mouths contain hazardous microorganisms like Staphylococcus aureus, methicillin resistant Staphylococcus, Candida albicans, and Pseudomonas aeruginosa with rate of 55.6%, 25.9%, 25.9%, and 5.6%, respectively [18]. 2006;48(2):75-87. 2018; 9:37. https://doi.org/10.4103/ijpvm.IJPVM_143_16. J. Appl. In the present survey, 0.525% hypochlorite sodium agent which is common in housework was used. Isopropyl alcohol is normally used as antiseptic. 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. At the last, three more samples were used as positive controls to check for any microbial pollution. Disinfection of impressions: A. 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. It is very useful disinfectant with advantages including fast bactericidal activity, ease of use as it is soluble in water, relatively stable, nontoxic at use concentrations, low cost, non-staining, noninflammable and colorless. Current status of knowledge,”, A. H. Rowe and J. O. Forrest, “Dental impressions. It can be postulated that the use of a more resistant type of bacteria can explain this difference. J Prosthet Dent. × 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. 8 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.
