Abstract:
The aim of this study was to determine quantitatively and qualitatively the inorganic particle fraction of commercially available dental elastomers. The inorganic volumetric fraction of two addition silicones (Reprosil Putty/Fluid and Flexitime Easy Putty/Fluid), three condensation silicones (Clonage Putty/Fluid, Optosil Confort/Xantopren VL and Silon APS Putty/Fluid), one polyether (Impregum Soft Light Body) and one polysulfide (Permlastic Light Body) was accessed by weighing a previously determined mass of each material in water before and after burning samples at 600ºC, during 3 h. Unsettled material samples were soaked in acetone and chloroform for removal of tthe organic portion. The remaining filler particles were sputter-coated with gold evaluation of their morphology and size, under scanning electron microscopy (SEM). Flexitime Easy Putty was the material with the highest results for volumetric particle fraction, while Impregum Soft had the lowest values. Silon 2 APS Fluid presented the lowest mean filler size values, while Clonage Putty had the highest values. SEM micrographs of the inorganic particles showed several morphologies - lathe-cut, spherical, spherical-like, sticks, and sticks mixed to lathe-cut powder. The results of this study revealed differences in particle characteristics among the elastometic materials that could lead to different results when testing mechanical properties.

Abstract:
Elastomers are synthetic rubber materials formed by polymers, which are joined by a small number of cross-links that form a three-dimensional network. The aim of the current study was to compare the surface detail reproduction of polyvinyl siloxane and polyether-based elastomeric impression materials (2 years after their expiration date) to the ones that have not exceeded this period-of-time. Four groups comprising 5 samples, each (n = 5), were divided based on material (polyvinyl siloxane – Express and polyether – Impregum Soft) and expiration date (expired, or not). The manipulated material was placed on a tray in a way to fully cover its inner part. Later on, it was placed on a metal matrix presenting 20-, 50- and 75-μm lines. Molds were removed after polymerization and surface detail reproduction was measured in comparator microscope (Stereozoom Microscope), along the 20 μm line (25 mm in length), at 4x-magnification, in compliance with ISO 4823. Surface detail reproduction values were subjected to descriptive analysis - results were expressed in percentage (%). All groups presented 100% of surface detail reproduction, regardless of impression material or expiration date. Surface detail reproduction of the investigated materials was not influenced by the evaluated elastomers’ expiration date.

Abstract:
Elastomer is often used to make an impression. In prosthodontics, impression material that have been exposed to infected saliva pose a main source of cross contamination in dental office and laboratories, therefore desinfection of impression is recommended by American Dental Association (ADA) to prevent possible transmission of infectious diseases. Piper betle L. 25% and sodium hypochlorite 0,5% can both be used as desinfection agent by spraying the impression materials. But some desinfection process can effect the dimensional accuracy of the impressions materials especially the hidrophilic materials. The aim of this study was to determine the influence of spray desinfection with piper betle L. 25% and sodium hypochlorite0,5% on dimensional accuracy of cast made by elastomeric impression materials. Type of this research was a laboratory experiment. The samples of this research were the cast made by elastomeric impression materials, two abutment preparations in shape with diameter (buco lingual)6.33 mm, height (occluso gingival) 8.02 mmand distance between the centers of the abutments 28.25 mm and total samples were 30 for 3 groups. The cast dimension was measured using digital caliper and dimensional accuracy test was analyzed with T-Independent test. The result showed that there was a statisticallyinfluence of spray desinfection with piper betle L. 25% and sodium hypochlorite0,5% on dimensional accuracy of cast made by elastomeric impression materials(p<0.05) and the percentage of the dimensional change is in normal range recommended by ADA 19 (<0,5%). Therefore, spray desinfection with piper betle L. 25% can be used in elastomeric impression materials.

Abstract:
Hydrocolloids were the first elastic materials to be used in the dental field. Elastic impression materials include reversible (agar-agar), irreversible (alginate) hydrocolloids and synthetic elastomers (polysulfides, polyethers, silicones). They reproduce an imprint faithfully, providing details of a high definition despite the presence of undercuts. With the removal of the impression, being particularly rich in water, the imprints can deform but later adapt to the original shape due to the elastic properties they possess. The advantages of using alginate include the low cost, a better tolerability on the part of the patient, the ease of manipulation, the short time needed for execution, the instrumentation and the very simple execution technique and possibility of detecting a detailed impression (even in the presence of undercuts) in a single step. A comprehensive review of the current literature was conducted according to the PRISMA guidelines by accessing the NCBI PubMed database. Authors conducted a search of articles in written in English published from 2008 to 2018. All the relevant studies were included in the search with respect to the characteristics and evolution of new marine derived materials. Much progress has been made in the search for new marine derived materials. Conventional impression materials are different, and especially with the advent of digital technology, they have been suffering from a decline in research attention over the last few years. However, this type of impression material, alginates (derived from marine algae), have the advantage of being among the most used in the dental medical field.

Abstract Aim To demonstrate the clinical feasibility of autoclaving certain silicone impression materials in order to avoid potential cross-contamination during handling, transport, and subsequent processing. Background Semicritical devices are recommended to be treated at least with high-level disinfectants or actually steam sterilized at 134°C. To date dental impressions have been disinfected rather than sterilized, so the question remains should they be sterilized before being sent to the dental laboratory? Case Descriptions Two identical impressions per case were made of metal-ceramic crown and fixed partial denture preparations on the same patient using addition type polyvinyl siloxane (PVS) impression materials (AFFINIS, R Coltene/ Whaledent AG, 9450 Altstatten, Switzerland) in different trays. The first impression (IMPx1) was cleaned and treated with an intermediate-level disinfectant (FD 322.Fast Disinfection Spray, Durr Dental, 74321 Bietigheim-Bissingen, Germany). The second impression (IMPx2) was cleaned, treated with an intermediate-level disinfectant as with IMPx1, subjected to a computer tomography (CT) scan with a dimensional resolution of ±10 μm, steam sterilized, and then subjected to a second CT scan. The dimensional changes of the second impression after steam sterilization were calculated by comparing the overlay of the two CT scans and expressed by color coding of the impression graphics. After the second scan, the impression was sent to a dental laboratory to fabricate a metal-ceramic crown or metal-ceramic fixed partial denture restoration to the one produced from the first impression (IMPx1) subjected only to disinfection. This process was repeated for four clinical cases. Conclusion Impressions made with AFFINIS® silicone impression materials in a rigid reinforced polycarbonate impression tray or in a metal dual-arch tray can be autoclaved. The overall dimensional stability of the impressions and the quality of single crowns and small fixed partial dentures made using IMPx2 was not compromised. The maximum dimensional differences at the preparations of the nonautoclaved and the autoclaved impressions were found to be within acceptable limits of about 50–100 ìm. Clinical Significance Steam sterilization of AFFINIS® impressions is possible without adversely affecting dimensional change. In addition, clinicians can clearly indicate to the dental practice and laboratory personnel that sterilization of the impressions has been performed, cross-contamination is unlikely, and the impressions present no apparent health hazard during transport and subsequent processing.

Abstract:
There are many steps in fabrication of dental crowns and bridges at which an error can occur, and a technician can only fabricate a quality restoration if the impression itself is of adequate quality. All dental practitioners should have the ability to evaluate the quality of dental impression before sending to the laboratory. Elastomeric silicones (polysiloxane) are the most utilised impression materials in dental practice. The present study deal with the deficiencies of silicones dental impressions sent to commercial dental laboratories for fabrication of single crowns and bridges.

Abstract:
Choosing an appropriate impression material is a challenge for many dentists, yet an essential component to provide an excellent clinical outcome and improve productivity and profit. The purpose of present study was to compare wettability, tear strength and dimensional accuracy of three elastomeric impression materials, with the same consistencies (light-body). Three commercially available light body consistency and regular set 3M ESPE Express polyvinylsiloxane (PVS), 3M ESPE Permadyne polyether (PE), and Identium (ID), impression materials were comparedTear strength test, contact angle test and linear dimensional accuracy were evaluated for three elastic impression material. Among the three experimental groups PE impression material exhibited the higher mean values of tear strength, followed by ID group then PVS which showed the lowest mean value. For wettability test, Polyether group exhibited the lowest mean values of contact angle, followed by mean values of contact angle of ID group, while the PVS group showed the highest contact angle. There was a significant difference in the linear distance measurements between the two parallel impression coping/analogue assembly of the working models obtained by using (Identium, 3M ESPE ExpressPVS , 3M ESPE Permadyne polyether) the polyether impression materials provide higher tear strengths and lower wettability than elastomer impression materials and Identium material have acceptable tear strengths and wettability. All three experimental impression materials were distorted in both conditions (angled and parallel implant situations)

Abstract:
ABSTRACT Context The elastomeric impression material is the most widely used impression material in contemporary dental practice; their accuracy is critical for the outcome of indirect restorations. The accurate duplicate cast obtained from single impression reduces the professional clinical time, patient inconvenience, and extra material cost. Aim To compare the accuracy of the cast obtained from various impression methods utilizing elastomer impression materials. Materials and methods The stainless steel working cast model assembly consisting of two abutments and one pontic area was fabricated. Two sets of six each custom aluminum trays were fabricated, with 5 mm spacer and 2 mm space. The impression methods evaluated in the study were additional silicone putty reline (two step), heavy-light body (one step), monophase (one step), and polyether (one step). Type IV gypsum casts were poured at intervals of 1, 12, 24, and 48 hours. The resultant cast was measured with a traveling microscope for comparative dimensional accuracy. The data obtained were subjected to analysis of variance test at significance level <0.05. Results The die obtained from putty reline two-step impression techniques had the percentage of variation for the height -0.36 to -0.97% with 0.40 to 0.90% increase in diameter. One-step heavy-light body impression dies recorded the increased width by 0.50 to 0.80% and height reduced by - 0.73 to -1.21%. The resultant dies from additional silicone monophase impressions had a percentage of variation for width 1.20% and height by-1.34%. The similar value for width and height for polyether was -1.46% and -1.30% respectively. Conclusion Putty reline technique dies had better dimensional accuracy after repeated pour followed by dies from heavy-light body additional silicone impression. Key message The multiple pour cast from putty reline elastomeric impressions is clinically acceptable, while cast from polyether was smaller in dimension.

ABSTRACT A meticulous impression is paramount for a precision fit of indirect restoration. Unfortunately, for many clinicians, making an impression for fixed prostheses is one of the challenging aspects in restorative dentistry. Advances in elastomeric chemistries have given birth to a new generation of impression materials: a combination of a polyvinyl and a polyether impression material, called vinyl siloxane ether. The purpose of this article is to explore the new impression material which is effective and efficient to obtain predictable, accurate, high quality impressions in dental practice.

Abstract:
Molding in a fixed prosthesis is one of the most important stages in rehabilitative treatment, as it is there that attempts are made to reproduce dental preparations and adjoining regions by using appropriate materials and techniques. Among the fixed prosthesis molding materials available on the market, the elastomers stand out, which are polymers where the prey occurs through the increase of the chain and the establishment of cross-links. The objective of the study is to present a clinical case and perform a literature review on the use of condensation silicone and addition to molds in Fixed Prosthesis. In this literature review, a survey of PubMed, Scielo and Lilacs data was performed, using the descriptors: Denture, Partial, Fixed; Dental Impression Materials and Elastomers. It is possible to conclude that in the field of Dentistry, the elastomers, among them the condensation-cured and addition-cured silicones, both provide high precision models and are the most used materials in works with fixed partial dentures. Therefore, it is up to the professional to know the properties and adapt to the best group of chosen materials.

O objetivo deste estudo foi analisar a influência de diversos métodos de desinfecção na estabilidade dimensional de elastômeros para moldagem, por meio de uma revisão de literatura. Para isso realizou-se pesquisa nas bases de dados PubMed, Scielo e ScienceDirect, utilizando-se os seguintes descritores e estratégias de busca: “elastomers” AND “desinfection” AND “dental impression materials”. Foram recuperados 116 artigos em inglês e português e selecionados 10, adotando como critério de inclusão: estudos laboratoriais publicados de 2007 a 2017, que abordassem a relação entre alterações dimensionais dos elastômeros e métodos de desinfecção. Os estudos analisaram 12 procedimentos de desinfecção, utilizando diferentes tempos de imersão e exposição em siliconas de condensação, de adição e poliéteres. Os métodos averiguados foram: a utilização de glutaraldeído 2% cloreto de benzalcônio hipoclorito de sódio 5,25% micro-ondas sabonete neutro orftalaldeído 0,55% autoclave fitoterápicos clorexidina 4% álcool GL 70° raios ultravioleta e ácido paracético. Todos os métodos provocaram alguma alteração dimensional nos elastômeros, especialmente nas siliconas de condensação. A contração foi observada principalmente nos materiais desinfectados com glutaraldeído 2%, sobretudo após a primeira hora de separação molde-modelo, entretanto, esta não foi superior a 1%. Conclui-se que, apesar de provocarem alterações nas dimensões dos moldes de elastômeros, os desinfetantes podem e devem ser utilizados, sem prejuízos do ponto de vista clínico.Palavras-chave: Elastomers.

Abstract:
Introduction: Saliva and blood contaminated impressions are often a source of cross contamination between the clinic and dental laboratory. Explicit communication and observance of an infection control protocol for handling of dental impressions must exist among the office staff as well as between office and dental laboratories. Though disinfection of impression is routinely followed, autoclaving elastomeric impression is an effective method of sterilization them. Objectives: The purpose of this study was to evaluate dimensional stability and detail reproduction of a new addition silicon impression material after disinfection. Methods: In this study, a total of twenty impressions for the master model using heat resistant plastic stock trays. The twenty impressions were divided into two groups according to disinfection technique: (Table 2) Group 1: (n=10) Control group, untreated impressions. (C.G) Group 2: (n=10) Impressions were chemically disinfected. (D.G). after all impressions treatment, they were poured with extra hard stone (type IV) to get stone casts. Dimensional accuracy and detail reproduction of the impression material were evaluated indirectly through the recovered improved stone casts from impressions of the master model using the travelling microscope. Results: Cross arch distance (A): Epoxy resin master model cross arch distance measurement (A) was (41.36 mm). 1.1 Measurements of the cross-arch distance of stone casts Control group (C.G): The mean and standard deviation values of distance (A) in stone models obtained from C.G. were 41.553 ± 0.170 mm. Disinfection group (D.G): The mean and standard deviation values of distance (A) in stone models obtained from D.G were 41.368 ± 0.083 mm. ANOVA test showed that there was a statistically difference shrinkage between the groups (P-value = 0.006). 1.2 Measurement of the dimensional changes in the cross-arch distance of the different groups. The mean and standard deviation values of cross arch distance changes in stone models of C.G. were 0.191 ± 0.170 mm. while dimensional changes in stone models obtained from D.G. were 0.006 ± 0.082 mm. Conclusion: The purpose of this study was to evaluate dimensional stability and detail reproduction of a new addition silicon impression material after disinfection. In this study an epoxy resin master model was duplicated from a modified dentate mandibular model. Within the limitations of this study, it could be concluded that Chemical disinfectant of polyvinyl siloxane impression material can be successfully used in making fixed partial dentures.

Abstract:
This study investigates 2 polyethers (PE), 2 polyvinylsiloxanethers (VXSE), and 10 polyvinylsiloxanes (PVS), seven of which had a corresponding light-body consistency and seven of which had a corresponding heavy-body consistency. Each light-body elastomer underwent a flowability test using the shark fin method 20, 50, and 80 s after mixing. The tear strength test DIN 53504 was used after setting the time (T0). Next, 24 h later (T1), hydrophilicity testing was used with static contact angles in water drops during polymerization (20, 50, and 80 s, as well as after 10 min). The heavy-body elastomers underwent shark fin testing with a corresponding light-body material at 50 and 80 s after mixing. The results of light-body testing were combined in a score to describe their performance. The highest differences were detected within flowability in shark fin heights between PE and a PVS (means of 15.89 and 6.85 mm) within the maximum tear strengths at T0 between a PVS and PE (3.72 and 0.75 MPa), as well as within hydrophilicity during setting between VXSE and a PVS (15.09° and 75.5°). The results indicate that VSXE and novel PVS materials can significantly compensate shortcomings in PE towards tear strength and hydrophilicity, but not flowability.

Abstract:
Abstract A quality-made dental impression is a prerequisite for successful fixed-prosthodontic fabrication and is directly dependent on the dimensional stability, accuracy and flexibility of the elastomeric impression materials, as well as on the appropriately used impression techniques. The purpose of this paper is to provide a literature review of relevant scientific papers which discuss the use of various silicone impression materials, different impression techniques and to evaluate their impact on the dimensional stability and accuracy of the obtained impressions. Scientific papers and studies were selected according to the materials used, the sample size, impression technique, storage time, type of measurements and use of spacer for the period between 2002 and 2016. In the reviewed literature several factors that influence the dimensional stability and accuracy of silicone impression molds, including the choice of the type of viscosity, impression material thickness, impression technique, retention of the impression material on the tray, storage time before the casting, number of castings, hydrophilicity of the material, release of byproducts, contraction after polymerization, thermal contraction and incomplete elastic recovery were presented. The literature review confirmed the lack of standardization of methodologies applied in the research and their great diversity. All findings point to the superiority of the addition silicone compared to the condensation silicone.

Abstract:
Objective. Anecdotal evidence suggests that impression materials and techniques used in general dental practice for fixed partial dentures vary from those taught in dental schools. The aim of this survey was to integrate impression techniques evolved all over the years for fixed partial dentures and to know the techniques and materials which are used in the present day by the practitioners. Materials and Methods. A total of 1000 questionnaires were sent to various practitioners in India, out of which 807 questionnaires were filled. Results. The results showed that 84.8% of prosthodontists (65.56%, urban areas) use elastomeric impression materials as well as irreversible hydrocolloids and 15.2% use irreversible hydrocolloid only. Amongst other practitioners, 55.46% use irreversible hydrocolloid (45%, rural and semiurban areas) and 44.54% use elastomeric impression materials. Elastomeric impression technique practiced most commonly is putty reline with/without spacer (77.2%); other techniques are multiple-mix and monophase techniques. Conclusion. The ideal materials, technique, and armamentarium are required for the long-term success of the treatment for fixed partial denture. Also, if the ideal procedure is not followed, it will lead to a compromised fit of the final prosthesis and failure of the treatment.

ABSTRACT Introduction Prosthodontic practice involves procedures in which impressions of the maxillary and mandibular arches are mandatory. Cross infection is one of the major problems that can occur in regular dental practice. Every dentist should take utmost care to prevent cross infection as oral cavity is the source of variety of microorganisms which can often cause diseases that can be fatal. Although precautions, such as wearing of gloves and mask, sterilization of instruments are given importance, the need for disinfection of impressions is often neglected. Hence, the aim of the study was to assess the disinfection potential of radiofrequency glow discharge (RGD) by microbiological studies. Materials and methods Disinfection potential of RGD on addition silicone (Reprosil, Dentsply, Milford DE, USA) was assessed. Total sample size was 20. Samples were divided into two groups of 10 each. Group I – control group and group II – RGD-treated group. Main groups were subdivided into subgroups A and B. Data collected were analyzed. Results The RGD-treated samples were found to be culture sterile which meant that there were no signs of growth of any organisms, thus proving the disinfection potential of RGD. Conclusion From this study, we can conclude that RGD is a very rapid and handy device, which can disinfect saliva contaminated elastomeric impression material surfaces. Clinical significance When compared with the difficulties and lack of efficiency encountered in disinfecting impressions by immersion and spray atomization, RGD can be very handy in dental clinics, as it is a very rapid and convenient method for infection control.

ABSTRACT Objective: The aim of this study was to evaluate the stability of elastomer through detail reproduction and its dimensional stability (DS) after disinfection with 0.2% chloramine-T. Materials and Methods: The elastomeric impression dental materials used in this study were polydimethylsiloxane (Oranwash L), polyvinyl siloxane (Express), polysulfide (Permlastic), and polyether (Impregum Soft). The entire press procedure was performed on a matrix in accordance with the ISO 4823. Detail reproduction was analyzed using an optical microscope (Stereozoom Microscope) over the 20-μm line with 25 mm of length at a magnification of ×4. DS was measured using an optical microscope (Scanning Tunneling Microscope) by subtracting the distance between the lines X and X’ over the 20-μm line on the matrix (DM) from the distance between the lines on the impression material (DI) divided by DM and multiplied by 100 establishing the equation: DS = ([DI – DM]/DM) ×100; then, 100% was added to the results of the equation. The detail reproduction values were subsequently subjected to descriptive analysis by percentage (%), and the DS values (%) were submitted to Kolmogorov–Smirnov test, two-way ANOVA (material × disinfectant), and Tukey’s test (α = 0.05). Results: All elastomeric impression materials showed 100% of detail reproduction, regardless of the disinfection procedure. Polysulfide (not disinfected) and polysulfide and polydimethylsiloxane (after disinfection with 0.2% chloramine-T) showed the smaller mean values of DS. Conclusion: According to the stability properties analyzed, chloramine-T can be used for disinfection of elastomer molds.

Abstract:
A replica method involving the use of a polyvinylsiloxane impression material with a resin cast, particularly suitable in the study of marine biofilms, is described. The technique has advantages over other methods in that it is quick, non-toxic, non-destructive and inexpensive. Replicas of critical-point dried eggcases of the dogfishScyliorhinus canicula(L.) (Elasmobranchii: Squaliformes) showed the replica to be true down to the size of bacteria. It was also possible to replicate larger areas such as patches of living barnacles on an intertidal rock.The study of marine biofilms often involves the use of destructive techniques such as conventional scanning electron microscopy (SEM), histology andin vacuospectroscopic methods (Baier & Meyer, 1986), so a single surface may not be examined repeatedly. Alternatively, the surface of interest may not be amenable to examination by standard techniques due to, for example, large size or incompatibility of the material of interest. In materials science the use of replica techniques to overcome such problems have been common (Goodhew, 1973), though techniques commonly involve the use of solvents (Loh, 1989) or silicone elastomers that may have a curing period of several hours (Gordon, 1984) and are consequently unsuitable for the study of biofilms. Scott (1982) reviewed the use of dental impression materials for field use in metallurgy and in recent years, dental impression materials have been used in the study of plant morphology (Green & Linstead, 1990). In this paper we consider the use of a hydrophilic polyvinylsiloxane impression material in the study of both microscopic and macroscopic marine biofilms.

Abstract In many areas of dental practice which involves exposure to blood and other body fluids, there is growing concern regarding improvements in cross-infection control. There is a need for disinfection methods to be effective while also being cheap, rapid, non-toxic, broad spectrum and easy to practice. Impression materials used in prosthodontics cannot be heat sterilized and are often damaged by chemical disinfection. In recent advances, ultraviolet disinfection method has begun to prove its effectiveness to control contamination of impression materials by killing microbes while preserving the quality of material. This scientific paper to be presented is on a study conducted to evaluate the effect of ultraviolet disinfection on the dimensional stability and infection control of elastomeric impression materials.

ABSTRACT Background There are a great amount of materials and techniques to use during dental prosthesis production that may confuse the dentist at the time of choice. Material's choice should be done considering ideal chemicophysical and biological properties and high detail reproduction. Aims The present study aimed to test the influence of differents impression materials and storage times on the dimensional accuracy of casting models. Materials and methods Four elastomeric materials– polysulfide, polyether, condensation silicone and addition silicone–were used to reproduce a master model of human teeth which were prepared for metaloceramic fixed prosthodontics. Six reference points were established on each tooth in order to determine four intervals: MD–mesial-distal, BL–buccal-lingual and CO–cervical-occlusal distance from premolar, and INT– interpillar distance–from the distal surface of the premolar to the mesial surface of the molar. The impressions were stored for half, 2 and 12 hours and pondered with a type IV gypsum. Results Cast measurements data were subjected to ANOVA (4 × 3), Tukey's – α = 0.05, Kruskal-Wallis and Dunn's tests – α = 0.05. The interaction between materials and storage time presented statistically significant for VP and CO intervals. For each storage time, materials presented dimensional alteration statistically significant. Conclusion Impression materials accuracy was affected by the storage time. All materials presented different dimensional accuracy when evaluated in a same period of time. Polysulfide was the only material that presented stable behavior over the time.

ABSTRACT Aim The aim of this study was to evaluate the influence of immersion period in two disinfectant solutions on dimensional change of four elastomeric impression materials. Materials and methods Four representative materials of each class of elastomers: Xantopren (polydimethylsiloxane—PDS), Express (polyvinyl siloxane—PVS); Permlastic (polysulfide— PS) and Soft Impregum (polyether—EP) were mixed according to manufacturers’ instructions and then inserted into a metal matrix prepared according to the specification of ISO 4823. The molds were removed from the matrix after 7 minutes and immersed in disinfectant solutions (sodium hypochlorite 0.5 and 2% glutaraldehyde) for 5, 10, 20, 30 and 60 minutes (n = 7), except the control group, which was not immersed. Once removed from solutions, the test samples were washed in water for 15 seconds, dried and measured three times, using a comparative optical microscope, with accuracy of 0.0005 mm. The analysis of variance with three criteria and Tukey's test with significance level of 5% showed that differences in linear dimensions of the materials analyzed were not statistically significant (p > 0.05) after soaking in sodium hypochlorite 0.5 and 2% glutaraldehyde, for the tested periods of time. Clinical significance Combinations of molding material and disinfecting solution can be used in the dental clinic for infection control, without changing the dimensional molds, for immersion periods not longer than 20 minutes.

Abstract:
ABSTRACTReplacement of missing ears is a challenging task in which extensive array of materials and techniques have been employed. This article describes a different and simplified procedure for fabricating auricular prostheses very similar to the intact left ear of the patient. A 65-year-old male patient was referred to the Department of Prosthodontics with the loss of the right ear. In this case, the impression was made using hydrocolloid material (alginate) from the both defected and the opposite side. After hardening of the stone casts, a custom-made transparent splint plate was designed for the left auricular side. The splint was reversed and a cast model of the right auricular side was obtained as pouring the dental stone into transparent orthodontic splint. After getting the impression from cast model, conventional wax pattern and try on process was done. Finally, silicone elastomer was polymerized and the retention of the prosthesis acquired with the magnetic attachments. The technique described is economical, conventional, and time-saving. Furthermore, the prosthesis imitates the patient's intact auricular tissue.

Abstract:
A review of the literature reveals an abundance of research papers which are focused on the physical properties and "simulated" clinical performance of impression materials. The three major developments during the past two decades were: (1) the introduction of the dimensionally stable addition silicones, (2) the development of dustless alginates, and (3) the reduction in technique sensitivity which resulted from the availability of automatic-mixing syringe tips. These syringe tips ensure consistently homogeneous mixtures of base and catalyst pastes with reduced waste. In addition, the more rapid mixing potential extends the traditional working time of the material. Little progress has been made toward correlating in vitro properties with in vivo performance. Since typical in vitro studies of impression materials are conducted under nearly ideal conditions, the information derived is of relatively limited value in predicting their clinical performance under more demanding conditions. Future research should focus more on clinically relevant properties, including freedom from porosity, viscosity-time relationships, tissue displacement potential, tear strength, elastic recovery, sensitivity to storage conditions, compatibility with die stones, degradation potential after exposure to disinfectant and sterilizing solutions, and ability to be re-poured accurately.

Abstract:
Major advances in impression materials and their application have occurred during the last decade, with greater emphasis being placed on rubber impression materials than on dental compound, zinc oxide-eugenol, and agar and alginate. Of particular interest has been the effect of disinfection solutions on the qualities of impressions and the biocompatibility of impression materials. The principal advance in hydrocolloids has been the introduction of the agar/alginate impression technique, which has simplified the procedure and improved the quality of gypsum dies compared with those prepared in alginate impressions. The tear strength of some alginates has been improved, and some have been formulated so that the powder is dustless, thus reducing the health hazard as a result of patient inhalation of dust during the dispensing process. Polyether and silicone impression materials have been modified so that the working time, viscosity, and flexibility of the polyethers have been improved and, with the introduction of addition silicones, their accuracy has become exceptional. Although the early addition silicones liberated hydrogen after setting, thus delaying the pouring of models and dies, most addition silicones have been improved so that no hydrogen is released and dies can be poured immediately. The introduction of automatic mixing systems for addition silicones has simplified their manipulation, has reduced the number of voids in impressions, and has reduced the amount of material wasted. The incorporation of surfactants into addition silicones has made them hydrophilic, with wetting properties similar to those of polyethers, and has made pouring bubble-free gypsum dies easier. This review is confined to published and unpublished information of the past decade. It will also suggest trends that should be anticipated in the near future based on this information. The review will not present information developed before 1975, which is available in several textbooks on dental materials by Craig (1985a), Phillips (1982), and Williams and Cunningham (1979).

The dimensional stability of dental impression materials is one of the variables that contribute to the accuracy or to the inexactitude of dentures. The rheological properties of several dental impression materials were determined by amplitude and frequency sweep tests. Deformation, storage modulus G’, loss modulus G” and complex viscosity η*were studied for each sample. Moreover, the texture, the stability of the shape, the capacity of distribution on different surfaces and the stability to storage for a long period of time were investigated. All these samples, characterized by a gel structure with G’>G”, are suitable as impression materials. Irreversible hydro-colloids) may be used for different kind of impressions because of their fidelity and elasticity; they also present medium time elasticity and may be easily prepared.

<p><strong>Objective:</strong> The aim of this study was to evaluate the internal and marginal adaptation of inlays fabricated from different types of impressions (conventional and digital) and different ceramics (feldspathic and lithium disilicate). <strong>Material and Methods:</strong> Forty premolars were prepared for all-ceramic inlay restoration and assigned to 4 groups (n=10), according to the impression method (conventional with addition silicone and digital impressions) and ceramic type (lithium disilicate and feldspathic ceramic blocks). For each type of impression, 10 inlays were fabricated from lithium disilicate blocks and the other 10 from feldspathic ceramic blocks, by means of the CAD-CAM system. The internal adaptation was analyzed by replica. The marginal fit was analyzed under a stereomicroscope by directly measuring the gap formed between the inlay and the tooth in the proximal and occlusal regions. <strong>Results:</strong> The marginal or internal adaptations were not affected by type of impression (conventional = digital impression), irrespective of the ceramic type. Only the internal adaptation was affected by material, i.e., feldspathic ceramic had lower values than disilicate ceramic, when considering the digital impression. <strong>Conclusion:</strong> The conventional and digital impressions promote similar marginal and internal adaptation of tested feldspathic and disilicate ceramic inlays. For digital impression the feldspathic ceramic showed better internal adaptation than lithium disilicate. </p><p><strong>Keywords</strong></p><p>Ceramics; Dental internal adaptation; Dental marginal adaptation; Dental impression technique.</p>

Abstract:
Background: Infection control is an imperative issue in the dental practice. Almost all of the dental procedures involve dealing with the saliva, blood and oral fluids which may have sufficient pathogens and cause cross infection through contaminated instruments, materials and surfaces. Therefore the dental health care workers must be aware of the possible contamination and should follow the measures to prevent it. The aim of the study is to assess the knowledge of dental health care professionals regarding infection control and modes of infection control employed by them during one of the dental procedure i.e. impression making. Methods: A self-assessment questionnaire based survey was carried out among dental health care professionals to assess the knowledge and practice of infection control in dental clinics. Survey instruments containing 14 questions were randomly distributed to 113 dental health care professionals regarding knowledge of infection control methods and infection control practice during impression making in dental clinics and hospitals. Data was collected and analyzed. Results: Though most of the health care professionals (88.6 %) think an impression taken from patient mouth will have enough pathogens to cause cross infection, our study showed that only 52.3 % of them disinfect all the impression and washing impression under running water was the method used for disinfection by the majority (78.9 %). Conclusions: The knowledge about infection control during impression making is better among the dental health care professionals. But there is a need to improve the practice to minimize cross infection in dental set up and reduce the associated morbidity and mortality rates for both dental practitioners themselves and patients.
