Abstract
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. To compare the accuracy of the cast obtained from various impression methods utilizing elastomer impression materials. 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. 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. Putty reline technique dies had better dimensional accuracy after repeated pour followed by dies from heavy-light body additional silicone impression. The multiple pour cast from putty reline elastomeric impressions is clinically acceptable, while cast from polyether was smaller in dimension. Haralur SB, Toman MS, Al-Shahrani AA, Al-Qarni AA.

Abstract
Prosthetic eyes often cause dryness, irritation, and inflammation of the anophthalmic sockets. To reduce the discomfort caused due to dryness of ocular prosthesis by a custom-made hollow ocular acrylic prosthesis, which is filled with lubricant drops slowly and systemically released into the ophthalmic cavity upon blinking. Thirty-eight patients wearing unilateral artificial eye for a period of more than 6 months were evaluated. An innovative customized hollow prosthesis is described, which was incorporated with a hollow reservoir containing a combination of a tear substitute along with cyclosporine A (0.05%) acting as the lubricant. The patients were then evaluated with the help of a questionnaire, regarding the comfort, dryness, soreness, and the ease of use of prosthesis. A self-formulated grading system was used to record the scores. Postinsertion of this hollow prosthesis, there was a marked reduction in the dryness, irritation, discomfort, and signs of inflammation. It was concluded that the continuous flow of the lubricant onto the dry prosthetic eye helps in reducing dryness, irritation, soreness, and inflammation. A hollow ocular prosthesis that can continuously discharge lubricant onto the dry prosthesis can help in increasing patient's acceptance and comfort. Gupta R, Aggarwal R, Bharat A, Nijhawan S.

Abstract
To compare the compressive strengths of composite resins and resin-modified glass ionomer cements (RMGICs) at different times. A total of 36 samples were prepared, 12 samples of each group, composite resins Filtek Z 250, Filtek Z 350, and resin-modified glass ionomer cement. Compressive strengths of specimens were measured after 1, 24 hours, and 7 days. Test was carried out on a “Universal Testing Machine” with cross-head speed of 5 mm/min. There was a significant difference between all the three restorative materials. Analysis of variance showed that mean compressive strengths of Z 250 after 1, 24 hours were higher than Z 350 and RMGIC (p < 0.05). The mean compressive strengths were reduced after 7 days in all the three groups, but after 7 days, the values of Z 250 when compared with the Z 350 and RMGIC were higher. The study demonstrated that compressive strengths of hybrid composite resins (Z 250) were significantly higher than that of nanocomposites (Z 350) and RMGIC. Sharma A, Mishra P, Mishra SK.

Abstract
Total glossectomy impairs various functions of tongue, such as mastication, speech, swallowing, and also results in psychological breach for the patient during social activities. In a glossectomy patient, the new size of the oral cavity often produces a change in the resonance associated with certain sounds. Also, due to the decrease in size and function of the tongue, interruption occurs in articulation patterns between the tongue, the hard and soft palate, and the teeth. We performed a review with a bibliographic search in Scopus, Web of Science along with the PubMed/Medline, Google scholar and internet. We included the articles with major contribution toward management of total glossectomy, excluded articles and works about surgical treatments in anatomical locations other than the oral cavity. To obtain maximum rehabilitation for these patients, the dentist must have a thorough knowledge of the physiologic processes involved in oral functions. The present article is an overview of various objectives and design concepts for rehabilitation of a total glossectomized patient. Yarramaneni V, Balakrishnan D, Aparna IN, Kapoor S.
