fa The Bonding of Glass Ionomer Cements to Caries-affected Primary Tooth Dentin کودکان Pediatric Dentistry پژوهشي Research <p> <strong>Purpose:</strong> </p><p> The purpose of this study was to evaluate the bonding of glass ionomer cements (GICs) to sound and caries-affected dentin by microtensile bond strength (μTBS) and nanoleakage (NL) tests. </p><p> <strong>Methods:</strong> </p><p> Occlusal cavity preparations were made in 36 sound primary molars. Half of the specimens were submitted to a pH-cycling model to create simulated caries-affected dentin. Teeth were randomly restored with one of the three materials: (1) resin-modified GIC with nanoparticles (Ketac N100 KN) (2) resin-modified GIC (Vitremer VI) and (3) high-viscosity GIC (Ketac Molar Easy Mix KM). Specimens were tested using a microtensile test (1 mm/minute). One specimen from each tooth was immersed in ammoniacal silver nitrate for 24 hours and revealed after eight hours to assess interfacial NL. The μTBS means were analyzed by 2-way analysis of variance and Tukey's post hoc test. For NL, Kruskal-Wallis and Mann-Whitney tests were used (P<.05). </p><p> <strong>Results:</strong></p><p>  No difference was found between sound and caries-affected dentin (P>.05). KM showed the lowest GIC-dentin μTBS values, while VI and KN showed higher values. Infiltration of ammoniacal silver nitrate into the adhesive interface was not affected by sound or caries-affected dentin. </p><p> <strong>Conclusion:</strong></p><p>  Caries-affected dentin does not jeopardize the bonding of glass ionomer cements to primary tooth dentin. </p><hr><p></p><p> <strong>Source: </strong>Journal of American Academy of ‍ Pediatric Dentistry</p><p><a href="http://www.ingentaconnect.com/content/aapd/pd/2013/00000035/00000004/art00003" target="_blank"><font color="#0000ff"> Full Text</font></a></p> DENTAL BONDING; DENTAL CARIES; GLASS IONOMER CEMENTS 0 0 http://idai.ir/browse.php?a_code=A-10-32-2572&slc_lang=fa&sid=1 Fabiana Bucholdz Teixeira Alves 100319475328460012167 100319475328460012167 No Department of Pediatric Dentistry, School of Dentistry, Universidade Estadual de Ponta Grossa, Ponta Grossa, Parana, Brazil Daniela Hesse 100319475328460012168 100319475328460012168 No Department of Pediatric Dentistry, School of Dentistry, Universidade de São Paulo, São Paulo, São Paulo, Brazil Tathiane Larissa Lenzi 100319475328460012169 100319475328460012169 No Department of Pediatric Dentistry, School of Dentistry, Universidade de São Paulo, São Paulo, São Paulo, Brazil Camila De Almeida Brandão Guglielmi 100319475328460012170 100319475328460012170 No Department of Pediatric Dentistry, School of Dentistry, Universidade de São Paulo, São Paulo, São Paulo, Brazil Alessandra Reis 100319475328460012171 100319475328460012171 No Department of Restorative Dentistry, School of Dentistry, Universidade Estadual de Ponta Grossa, Ponta Grossa, Parana, Brazil Alessandro Dourado Loguercio 100319475328460012172 100319475328460012172 No Department of Restorative Dentistry, School of Dentistry, Universidade Estadual de Ponta Grossa, Ponta Grossa, Parana, Brazil Thiago Saads Carvalho 100319475328460012173 100319475328460012173 No Department of Pediatric Dentistry, School of Dentistry, Universidade de São Paulo, São Paulo, São Paulo, Brazil Daniela Prócida Raggio danielar@usp.br 100319475328460012174 100319475328460012174 Yes Department of Pediatric Dentistry, School of Dentistry, Universidade de São Paulo, São Paulo, São Paulo, Brazil
