title: Dental ceramics: a review of new materials and processing methods

description: Abstract The evolution of computerized systems for the production of dental restorations associated to the development of novel microstructures for ceramic materials has caused an important change in the clinical workflow for dentists and technicians, as well as in the treatment options offered to patients. New microstructures have also been developed by the industry in order to offer ceramic and composite materials with optimized properties, i.e., good mechanical properties, appropriate wear behavior and acceptable aesthetic characteristics. The objective of this literature review is to discuss the main advantages and disadvantages of the new ceramic systems and processing methods. The manuscript is divided in five parts: I) monolithic zirconia restorations; II) multilayered dental prostheses; III) new glass-ceramics; IV) polymer infiltrated ceramics; and V) novel processing technologies. Dental ceramics and processing technologies have evolved significantly in the past ten years, with most of the evolution being related to new microstructures and CAD-CAM methods. In addition, a trend towards the use of monolithic restorations has changed the way clinicians produce all-ceramic dental prostheses, since the more aesthetic multilayered restorations unfortunately are more prone to chipping or delamination. Composite materials processed via CAD-CAM have become an interesting option, as they have intermediate properties between ceramics and polymers and are more easily milled and polished.

title: Randomized clinical trials of dental bleaching – Compliance with the CONSORT Statement: a systematic review

description: Abstract We reviewed the literature to evaluate: a) The compliance of randomized clinical trials (RCTs) on bleaching with the CONSORT; and b) the risk of bias of these studies using the Cochrane Collaboration risk of bias tool (CCRT). We searched the Cochrane Library, PubMed and other electronic databases, to find RCTs focused on bleaching (or whitening). The articles were evaluated in compliance with CONSORT in a scale: 0 = no description, 1 = poor description and 2 = adequate description. Descriptive analyses of the number of studies by journal, follow-up period, country and quality assessments were performed with CCRT for assessing risk of bias in RCTs. 185 RCTs were included for assessment. More than 30% of the studies received score 0 or 1. Protocol, flow chart, allocation concealment and sample size were more critical items, as 80% of the studies scored 0. The overall CONSORT score for the included studies was 16.7 ± 5.4 points, which represents 52.2% of the maximum CONSORT score. A significant difference among journal, country and period of time was observed (p &lt; 0.02). Only 7.6% of the studies were judged at “low” risk; 62.1% were classified as “unclear”; and 30.3% as “high” risk of bias. The adherence of RCTs evaluating bleaching materials and techniques to the CONSORT is still low with unclear/high risk of bias.

title: Efficiency of polymerization of bulk-fill composite resins: a systematic review

description: Abstract This systematic review assessed the literature to evaluate the efficiency of polymerization of bulk-fill composite resins at 4 mm restoration depth. PubMed, Cochrane, Scopus and Web of Science databases were searched with no restrictions on year, publication status, or article’s language. Selection criteria included studies that evaluated bulk-fill composite resin when inserted in a minimum thickness of 4 mm, followed by curing according to the manufacturers’ instructions; presented sound statistical data; and comparison with a control group and/or a reference measurement of quality of polymerization. The evidence level was evaluated by qualitative scoring system and classified as high-, moderate- and low- evidence level. A total of 534 articles were retrieved in the initial search. After the review process, only 10 full-text articles met the inclusion criteria. Most articles included (80%) were classified as high evidence level. Among several techniques, microhardness was the most frequently method performed by the studies included in this systematic review. Irrespective to the “in vitro” method performed, bulk fill RBCs were partially likely to fulfill the important requirement regarding properly curing in 4 mm of cavity depth measured by depth of cure and / or degree of conversion. In general, low viscosities BFCs performed better regarding polymerization efficiency compared to the high viscosities BFCs.

title: Polymerization shrinkage stress of composite resins and resin cements – What do we need to know?

description: Abstract Polymerization shrinkage stress of resin-based materials have been related to several unwanted clinical consequences, such as enamel crack propagation, cusp deflection, marginal and internal gaps, and decreased bond strength. Despite the absence of strong evidence relating polymerization shrinkage to secondary caries or fracture of posterior teeth, shrinkage stress has been associated with post-operative sensitivity and marginal stain. The latter is often erroneously used as a criterion for replacement of composite restorations. Therefore, an indirect correlation can emerge between shrinkage stress and the longevity of composite restorations or resin-bonded ceramic restorations. The relationship between shrinkage and stress can be best studied in laboratory experiments and a combination of various methodologies. The objective of this review article is to discuss the concept and consequences of polymerization shrinkage and shrinkage stress of composite resins and resin cements. Literature relating to polymerization shrinkage and shrinkage stress generation, research methodologies, and contributing factors are selected and reviewed. Clinical techniques that could reduce shrinkage stress and new developments on low-shrink dental materials are also discussed.

title: Light curing in dentistry and clinical implications: a literature review

description: Abstract Contemporary dentistry literally cannot be performed without use of resin-based restorative materials. With the success of bonding resin materials to tooth structures, an even wider scope of clinical applications has arisen for these lines of products. Understanding of the basic events occurring in any dental polymerization mechanism, regardless of the mode of activating the process, will allow clinicians to both better appreciate the tremendous improvements that have been made over the years, and will also provide valuable information on differences among strategies manufacturers use to optimize product performance, as well as factors under the control of the clinician, whereby they can influence the long-term outcome of their restorative procedures.

title: Study of the block/grout interface in concrete and clay block masonry structures

description: ABSTRACT This work aims to study the behavior of the block/grout interface for concrete and clay block masonry. This was achieved by push-out and pull-out experimental tests including reinforcement bar in the latter one. The experimental result showed that there is a good bond between the concrete blocks internal faces and the grout, enough to prevent infill-slippage, and that the whole tensile strength of the usual reinforcement bars is achieved provided they are properly anchored. Nevertheless, for clay blocks there is a low bond between the clay blocks internal faces and the grout, allowing the infill-slippage before the reinforcement bars reach their yield stress.

title: Evaluation by Experts and Designated Users on the Learning Strategy using SketchUp Make for Elevating Visual Spatial Skills and Geometry Thinking

description: Abstract The teaching and learning of Geometry should be meaningful and not merely reacting to the teacher's stimuli. Hence, students should be given opportunities to experiment when learning mathematics through exploration and investigation of geometric shapes by themselves. For that reason, a Learning Strategy for 3-dimensional Geometry using the SketchUp Make dynamic software, called LSPE-SUM was designed through a step-by-step instruction to help students to improve their visual spatial skills and geometric thinking. Visual spatial skills were carefully integrated onto each van Hiele levels of Geometry thinking through specific arrangement of specially crafted learning activities. Such arrangement was vital to ensure that students could achieve better cognitive enhancement in visual spatial skills by communicating and interacting physically and socially according to the hierarchical van Hiele model of Geometry thinking. LSPE-SUM capitalized the dynamic features of SketchUp Make to facilitate the elevation of visual spatial skills and Geometry thinking during the learning processes. The whole process of designing and developing the LSPE-SUM adopted the five cyclic stages of ADDIE instructional design model. The purpose of this article was to report the details of the final two stages, more specifically, implementation and evaluation of LSPE-SUM. This learning strategy was tried out twice upon twelve different students in a classroom setting over a period of 3 weeks each. Besides that, LSPE-SUM was also given to experts to obtain their views and evaluation on its functionality. Quantitative and qualitative approaches were used to collect data as well as to analyze the experts and students’ views on the suitability of LSPE-SUM. Analysis of students’ views suggested that LSPE-SUM has assisted most of them in elevating both their visual spatial skills and Geometry thinking; while, all experts claimed that LSPE-SUM was pedagogically functional and served its purposes well.

title: Evaluation of preoperative subconjunctival single application of mitomycin C in primary pterygium

description: Abstract Pterygia are usually benign lesions that do not require specific treatment. It is a fibrovascular growth onto the nasal side of the cornea. It`s cause has not been fully elucidated yet, but seems to be related to long -term ultraviolet ray exposure. When symptoms are not controlled with conservative treatment surgery is considered, but the recurrence rate is still high, and efforts have been made to avoid it. Mitomycin C (MMC) is a fibroblast proliferation inhibitor that can be used as adjuvant to surgery to reduce recurrence. We report here a case that describes pterygium surgery performed in both eyes of the same patient, being one with MMC and the other eye without it. Both pterygium were sent to laboratory analysis. The results and proliferation index were compared between the eyes.

title: Unilateral floppy eyelid syndrome with ipsilateral intolerance to brimonidine

description: Abstract The authors report a case of unilateral floppy eyelid syndrome with ipsilateral intolerance to brimonidine in a 65-year-old man. The singularity of this case is the combination of two rare illnesses of great phlogistic potentiality in the same eye. The purpose of this article is to report a case of unilateral floppy eyelid syndrome with ipsilateral intolerance to brimonidine, emphasizing a possible relation between them. The result was a unilateral keratopathy that emulated an intraepithelial neoplasia. The key to solving the problem was an unexplained anterior uveitis that raised the suspicion of drug toxicity.The upper eyelid eversion of the affected eye during sleep seemed to be the common denominator of both ailments. The bizarre aspect of the epitheliopathy most likely resulted from the combination of trauma, insufficient lubrication, and drug intolerance.
