Resumo: | Aim: In the first article, the Systematic Review sought previous studies from the last 10 years, which investigated direct restorations in teeth endodontically. In the second article it was evaluate, in vitro, the fracture load of cavity preparations restored with transfixed posts and bulkfill composite resin. Methods: A search was carried out in the health sciences databases (The Cochrane Library, Embase, PubMed-MEDLINE, LILACS, Web of Science, BBO, SCOPUS, Scielo e Science Direct) including articles published until October 2019. Eighty extracted human third molars were randomly divided into eight groups (n=10): G1 ? sound teeth; G2 - endodontic treatment + transfixed fiberglass post + composite resin; G3 - transfixed fiberglass post + composite resin; G4 ? endodontic treatment + transfixed zirconia posts + composite resin; G5 - transfixed zirconia post + composite resin; G6 ? endodontic treatment; G7 ? composite resin; G8 ? endodontic treatment + composite resin. The specimens were subjected to mechanical cycling with a vertical load of 200 N. Then, the fracture load test was performed in a universal testing machine with a cross-head speed of 1 mm/minute. The types of fracture were analyzed. Results: Based on the results of the Systematic Review, it is concluded that using glass ionomer cement and transfixing fiberglass pins in the dental crown, favor the increased fracture load in endodontically treated teeth. In the in vitro study, according to the Analysis of Variance and Tukey's test (p<0.05), G1 (3666 N) obtained the highest fracture load, not differing significantly from G3 (2856 N) and G5 (2738 N). G7 (2586 N) did not differ significantly from G3, G5 and G2 (1643 N). The lowest fracture load was obtained for G6 (844 N), which did not differ significantly from G2, G4 (1571 N), G8 (1398 N). G3 showed 100% of repairable failures, and G7 obtained 100% of irreparable failures. G1, G2 and G5 obtained 80% of repairable failures. G4 and G6 showed 60% of repairable failures. There were 50% of repairable failures and 50% of irreparable failures in G8. Conclusions: Using glass ionomer cement as a liner for direct restorations improves their longevity. The use of fiberglass or zirconia posts transfixed in MOD preparations, with or without endodontic treatment and restored with composite resin, had similar behaviors regarding the fracture load, with predominance of repairable fractures. |

No segundo artigo, avaliou-se, in vitro, a carga de fratura de preparos cavit?rios restaurados com pinos transfixados e resina composta bulkfill. M?todos: Foi realizada uma busca nas bases de dados das ci?ncias da sa?de (The Cochrane Library, Embase, PubMed-MEDLINE, LILACS, Web of Science, BBO, SCOPUS, Scielo e Science Direct.), incluindo artigos publicados at? outubro de 2019. Oitenta terceiros molares humanos extra?dos foram divididos aleatoriamente em oito grupos (n=10): G1 - h?gidos; G2 - tratamento endod?ntico + pino de fibra de vidro transfixado + resina composta; G3 - pino de fibra de vidro transfixado + resina composta; G4 - tratamento endod?ntico + pino de zirc?nia transfixado + resina composta; G5 - pino de zirc?nia transfixado + resina composta; G6 - tratamento endod?ntico; G7 - resina composta; G8 - tratamento endod?ntico + resina composta. Os corpos de prova foram submetidos ? ciclagem mec?nica com carga vertical de 200 N. Na sequ?ncia, foi realizado o teste de carga de fratura em m?quina de ensaio universal com velocidade de 1 mm/minuto. Os tipos de fratura foram analisados. Resultados: Com base nos resultados da Revis?o Sistem?tica, conclui-se que utilizar cimento de ion?mero de vidro e transfixar pinos de fibra de vidro na coroa dent?ria, favorecem o aumento de carga de fratura em dentes tratados endodonticamente. No estudo in vitro, de acordo com An?lise de Vari?ncia e teste de Tukey (p<0,05), G1 (3666 N) obteve a maior m?dia de carga de fratura, n?o diferindo estatisticamente do G3 (2856 N) e G5 (2738 N). G7 (2586 N) n?o diferiu estatisticamente do G3, G5 e G2 (1643 N). O menor valor de carga de fratura foi obtido para o G6 (844 N), n?o diferindo estatisticamente de G2, G4 (1571 N), G8 (1398 N). O G3 apresentou 100% de falhas repar?veis, e o G7 100% de falhas irrepar?veis. G1, G2 e G5 obtiveram 80% de falhas repar?veis. No G4 e G6 ocorreram 60% de falhas repar?veis. No G8 ocorreu 50% de falhas repar?veis e 50% de falhas irrepar?veis. Conclus?es: Utilizar cimento de ion?mero de vidro como forramento de restaura??es diretas melhora a longevidade das mesmas. A utiliza??o de pinos de fibra de vidro ou de zirc?nia transfixados em preparos MOD, sem ou com endodontia, e restaurados com resina composta tiveram comportamentos semelhantes quanto ? carga de fratura, havendo predomin?ncia de fraturas repar?veis.Submitted by PPG Odontologia (odontologia-pg@pucrs.br) on 2021-11-30T13:31:47Z No. of bitstreams: 1 CLAUDIA_FREITAS_DE_MOURA_MODENA_TES.pdf: 1872405 bytes, checksum: 4f61e084318a5f0ed04d86a4f69d4639 (MD5)Approved for entry into archive by Sheila Dias (sheila.dias@pucrs.br) on 2021-12-06T18:04:28Z (GMT) No. of bitstreams: 1 CLAUDIA_FREITAS_DE_MOURA_MODENA_TES.pdf: 1872405 bytes, checksum: 4f61e084318a5f0ed04d86a4f69d4639 (MD5)Made available in DSpace on 2021-12-06T18:20:42Z (GMT).
