17. Synthesis and characterization of poly(vinyl alcohol)/chondroitin sulfate composite hydrogels containing strontium‐doped hydroxyapatite as promising biomaterials.

Author

Grazioli, Guillermo, Silva, Adriana F., Souza, Jaqueline F., David, Carla, Diehl, Lisiane, Sousa‐Neto, Manoel D., Cava, Sergio S., Fajardo, André R., and Moraes, Rafael R.

Abstract

Novel poly(vinyl alcohol)/chondroitin sulfate (PVA/CS) composite hydrogels containing hydroxyapatite (HA) or Sr‐doped HA (HASr) particles were synthesized by a freeze/thaw method and characterized aiming towards biomedical applications. HA and HASr were synthesized by a wet‐precipitation method and added to the composite hydrogels in fractions up to 15 wt%. Physical–chemical characterizations of particles and hydrogels included scanning electron microscopy, energy‐dispersive spectroscopy, Fourier‐transform infrared spectroscopy, X‐ray diffraction, thermogravimetry, porosity, compressive strength/elastic modulus, swelling degree, and cell viability. Particles were irregular in shape and appeared to have narrow size variation. The thermal behavior of composite hydrogels was altered compared to the control (bare) hydrogel. All hydrogels exhibited high porosity. HA/HASr particles reduced total porosity without reducing pore size. The mechanical strength was improved as the fraction of HA or HASr was increased. HASr particles led to a faster water uptake but did not interfere with the total hydrogel swelling capacity. In cell viability essay, increased cell growth (above 120%) was observed in all groups including the control hydrogel, suggesting a bioactive effect. In conclusion, PVA/CS hydrogels containing HA or HASr particles were successfully synthesized and showed promising morphological, mechanical, and swelling properties, which are particularly required for scaffolding.

23. Current trends and future perspectives of dental pulp capping materials: A systematic review.

Author

da Rosa, Wellington L. O., Cocco, Alexandra R., Silva, Tiago M. da, Mesquita, Luana C., Galarça, Arthur Dias, Silva, Adriana F. da, and Piva, Evandro

Abstract

Abstract: To systematically review the literature to analyze the current trends and future perspectives of dental pulp capping materials through an analysis of scientific and technological data. This study is reported in accordance with the PRISMA Statement. Nine databases were screened: PubMed (MedLine), Lilacs, IBECS, BBO, Web of Science, Scopus, SciELO, Google Scholar, and The Cochrane Library. Additionally, the following patent applications were searched online in Questel Orbit (Paris, France), USPTO, EPO, JPO, INPI, and Patentscope databases. A total of 716 papers and 83 patents were included. Calcium hydroxide was the main type of material studied, especially for direct pulp capping, followed by MTA. Patents related to adhesives or resins increased from 1998 e 2008, while in the last years, a major increase was observed in bioactive materials (containing bioactive proteins), materials derived from MTA (calcium silicate, calcium phosphate and calcium aluminate‐based cements) and MTA. It was possible to obtain a scientific and technological overview of pulp capping materials. MTA has shown favorable results in vital pulp therapy that seem to surpass the disadvantages of calcium hydroxide. Recent advances in bioactive materials and those derived from MTA have shown promising results that could improve biomaterials used in vital pulp treatments. © 2017 Wiley Periodicals, Inc.

35. Comparative Effectiveness of Dental Anatomy Carving Pedagogy: A Systematic Review

Author

Azevedo, Renato de A., Rosa, Wellington Luiz de O., Silva, Adriana F., Correa, Marcos B., Torriani, Marcos A., and Lund, Rafael G.

Abstract

The aim of this study was to review the effectiveness of methods used for teaching dental anatomy carving to dental students in operative dentistry as evaluated in published studies. This systematic review is described in accordance with the PRISMA statement. Two independent reviewers performed a systematic literature search of research published from January 1945 until May 2014. Seven databases were screened: MedLine (PubMed), Lilacs, IBECS, Web of Science, Scopus, SciELO, and The Cochrane Library. After removing duplicates, only studies using dental carving to assess the practical knowledge of anatomy were selected. The tabulated data were organized by title of article, names of authors, number of students assessed, assessment method, material used, groups tested, main results, and conclusions. The methodology quality was assessed according to the Cochrane Handbook for Systematic Reviews of Interventions. Initially, 2,258 studies were identified in all databases. Five articles met the eligibility criteria and were included in this review. According to these studies, the geometric method, teaching step‐by‐step along with the teacher, and adjuvant methods such as the use of tutors and teaching through digital media with DVDs proved to be effective in improving learning. There is no standard technique that is widely accepted for the teaching of dental carving, nor is there an appropriately validated method of evaluation to verify whether the teaching methods used are effective for the acquisition of skills and expertise in dental anatomy by students.

36. Histologic Response and Tenascin and Fibronectin Expression After Pulp Capping in Pig Primary Teeth With Mineral Trioxide Aggregate or Calcium Hydroxide.

Author

Leites, Antonio B., Baldissera, Elaine Z., Silva, Adriana F., Tarquinio, Sandra, Botero, Tatiana, Piva, Evandro, and Demarco, Flávio F.

Subjects
FIBRONECTINS, TENASCIN, DENTAL pulp, CALCIUM hydroxide, DENTAL glass ionomer cements
Abstract

This study evaluated the histological response and the expression of tenascin (TN) and fibro-nectin (FN) after pulp capping with mineral trioxide aggregate (MTA) or calcium hydroxide (CH). Class V cavities and pulp exposure were performed in 40 primary pig teeth. The pulps were capped with either MTA or CH, and the cavities were sealed with resin-modified glass ionomer cement. CH was used as a control. Seven and 70 days posttreatment, the animals were sacrificed and teeth were prepared for histological evaluation. TN and FN were detected by immunostaining. A severe inflammatory response was observed after 7 days in the CH group (p<0.043), while in the MTA group, a mild response was observed. Similar reparative dentin deposition was observed after 70 days for both groups (p<0.005). The expression of FN and TN was similar for both groups in the two periods evaluated. TN and FN were expressed during pulp reparative events, independently of the capping material. [ABSTRACT FROM AUTHOR]
