Statement of Problem: Dental impressions are infected with various types of micro-organisms e.g. Hepatitis B, C, HIV, Mycobacterium, Herpes simplex, Ebola etc. In order to prevent their spread through dental impression it is important to sterilize the impression just after removal from patient’s mouth. Numerous method to disinfect impressions have been described in literature having their own advantages, disadvantages and effects on impression material. To enhance the knowledge of a dental health care workers about impression disinfection, a structured literature review of the current disinfection techniques has been carried out.
Material and Method: One electronic database (PubMed) was searched through in November 2019. The term “dental impression disinfection” was chosen. The titles and abstracts were screened and the studies which performed “disinfection techniques in dentistry” were selected.
Conclusions: Cross infection control is very important aspect of clinician and patient safety. It is the responsibility of the dentist to make appropriate choice of disinfection method for different impression materials.

Impression materials are used to record intraoral structures for the fabrication of definitive restorations. Accurate impressions are necessary for construction of any dental prosthesis. The relationship between static and mobile oral structures must be reproduced accurately for an optimum cast. Making a cast in gypsum materials from an impression of dental anatomy aids dentists in designing and constructing removable and fixed prostheses. The accuracy of these final restorations depends greatly on the impression materials and techniques. Accurate impressions depend on identifying the applications that do or do not fit each material’s characteristics. Materials used without adequate knowledge of their characteristics can impair a successful outcome. Often, the choice of impression materials depends on the subjective choice of the operator based on personal preferences and past experience with particular materials.Keywords

Proper occlusal relationships are a part of successful prosthetic treatment for edentulous patients. Fabrication of complete dentures involves clinical and laboratory procedures that should be performed precisely for achieving success with fabricated dentures. These occlusal errors can be corrected, (1) in a patient’s mouth or (2) by recording new centric relation and remounting dentures on an articulator. The second method is more viable because the denture base moves over the oral mucosa which is unable to identify premature contacts in centric occlusion and tooth guided eccentric excursions.This article depicts the modest and effective clinical chairside remounting procedure.Keywords

The success of any fixed prosthesis is multifactorial right from preparation to passive fit during cementation,various phases both in clinical and laboratory procedures. Die preparation is a procedure without which the success of any prosthesis is compromised. Different systems have been used for preparing die which serves as a platform for the construction of pattern for future prosthesis. Over the years, these die systems passed various modifications and innovations striving towards precision that governs the fit of any prosthesis. This article evaluates two such systems which evolved independently for their positional accuracy through-out a simulated laboratory procedure.Keywords

Background: Wettability of impression materials is essential to obtain a void-free cast. The purpose of this study was to evaluate the wettability of the impression materials immediately after setting and also to determine the change in wettability after 24 hours.
Materials and Method: Four impression materials were selected among which two were hydrocolloids and two were elastomers. Fifteen samples of each were experimentally tested immediately and 24 hours after sample preparation. Data obtained were subjected to t-test and analysis of variance for statistical comparisons at a 5% level of significance.
Results: The contact angle values were recorded immediately and 24 hours after setting. Lesser the contact angle value more the wettability of the impression material. The changes in wettability with respect to time were statistically analysed and it showed a statistically significant difference between the materials both immediately and after 24 hours.
Conclusion: Within the limitations of the study, Elastomers showed better wettability when compared to the hydrocolloids at both time interval and they have negligible time dependant change. Newly introduced cream alginate showed better wettability at both time intervals equivalent to the elastomers and can be considered for usage.

Many elder groups have been studied to determine their frequency of dry mouth complaints and their salivary flow rates. To appreciate these it is first necessary to understand two related concepts. First, complaints of dry mouth (or xerostomia) may not reflect reduced salivary function may instead reflect dehydration or other systemic conditions. Therefore studies that only examine the complaints of dry mouth will not reflect the true risk for oral diseases in the population. Second, it is very difficult to determine values for normal salivary function. Other studies suggest that salivary flow rates in elders are related to the number of medications they take on a regular basis, time number of systemic disorders they report, and the length of time for which they consume the drugs.Keywords

Background: Primary Implant Stability of dental implants is an essential factor for achieving successful osseointegration. The quality of bone is one of the most crucial factors that affects primary implant stability.
Sufficient bone to implant contact [BIC] is an essential criterion for biomechanically stable dental implant.
Osseodensification, a recently developed technique has been at the forefront of evolutionary changes in osteotomy site preparation in implantology. This technique involves low plastic deformation of bone that is created by rolling and sliding contact using a densifying bur that is fluted such that it densifies the bone with minimal heat elevation. This technique has been proposed to help in better osteotomy preparation, bone density and increases primary implant stability.
Method: A literature review was done to analyse the osseodensification procedure, its advantages over conventional osteotomy on bone density and primary implant stability.
Conclusion: Densifying drills [Densah] for bone osseodensification resulted in undersized osteotomy compared to conventional drills. It also resulted in improved bone density and increase in percentage bone volume and bone to implant contact, thereby improving implant stability.

Background: The science of dental impression materials must be necessity encompass a knowledge and appreciation of certain biological consideration that are associated with the selection and use of materials designed for the oral cavity. The minute amounts of components that leach out of impression materials are most unlikely to cause toxic reactions, locally or systemically. Reliable analysis data is therefore necessary to clarify the varied issues of safety and frequency of adverse reactions normally medicine, together with dentistry treatment.
Method: A literature review was done to analyse the biological considerations of dental impression materials and its hazards.
Conclusion: Many potential problems exist, but few documented adverse reactions have been published. It is expected that one requirement will be for clinicians and manufacturers to report biological side effects associated with use of the materials to certifying bodies or health authorities. Reliable research information using robust methodology is therefore required to clarify the varied questions of safety and frequency of adverse reactions in general dentistry, including Prosthodontic treatment.

Statement of Problem: Colour and shade selection is an important parameter which is essential in aesthetic replacement, thereby enhancing the psychology of the geriatric patient. Though its effectiveness is well known, its use is seen to be restricted. With current advancements in shade matching, its utility needs a systematic review.
Objective: The objective of this is to review about the improvement in aesthetics in the construction of complete denture by selection of the appropriate colour and shade matching similar to natural tooth in geriatric patients.
Method: Using various key words, an electronic search was performed from several databases-Medline/Pubmed, Cochrane Library and Google scholar. Furthermore, a manual searching of relevant journals and bibliographies of reviews was performed. Studies, which met the relevant criterias were selected for full text reading.
Results: This systematic review started with search various relevant articles, which were finally narrowed down to eighteen according to the inclusion criteria.
Conclusion: A thorough knowledge about the science of colour and shade selection is essential to the success in the field of Prosthodontics. It should be approached in a methodical manner. This enables the dentists to make the best choice and communicate it appropriately to the laboratory.
Clinical Significance: Even though the benefits of Shade matching are yet to be proven, evidences so far have not shown any adverse effects associated to shade matching. This means that the decisions made by clinicians whether or not to use shade matching depends upon clinical evaluation, patient physical and psychological health.

Prosthodontic rehabilitation of a patient with few teeth remaining is always challenging for a dentist. Over denture is a complete or partial denture prosthesis supported partly by soft tissues and partly retained by natural teeth and is a viable option when compared with conventional complete denture. The concept of conventional tooth-retained overdentures is a simple and cost effective treatment than the implant overdentures. When few firm teeth are present in compromised dentition, they can be retained and used as abutments for overdenture fabrication. This helps to improve the retention and stability of the final prosthesis significantly. The following case report discusses the use of resilient stud attachments to retain maxillary and mandibular overdentures.Keywords

Background: Interocclusal recording materials are generally used in prosthetic dentistry to register the jaw relationship. These materials have a wide range of viscosity, elasticity, and volumetric changes within various material groups. Newer elastomeric interocclusal materials are chemical modifications of elastomers whose comparative properties relevant to clinicians are yet to be studied.
Aims: To compare the dimensional change between the polyvinylsiloxane bite registration materials manufactured by different brands within the duration of 12 hours, 24 hours, and 48 hours storage.
Methodology: The dimensional changes of the different polyvinylsiloxe bite registration pastes were compared three-dimensionally in different time intervals with the standardised die measurement was 25mm between the vertical lines.
Conclusion: Within the limitations of the study, it was found that all 3 interocclusal recording materials NEOSILK, CADBITE, AND O-BITE showed no significant distortion when stored in-vitro for 12 hours. All Materials showed significant distortion when stored in-vitro for 24 hours and 48 hours. All three materials showed more distortion when stored in 48hours compare to 24 hours. Among polyvinyl siloxane interocclusal recording materials NEOSILK showed better dimensional stability when compared with CADBITE and O-BITE when stored in-vitro 24hours and 48hours. Hence we recommend Neosilk bite material for better dimensional stability when compare with other materials.
