Endodontically treated posterior teeth restored with or without crown restorations: A 5‐year retrospective study of survival rates from fracture

Abstract

Aim The aim of the present study was to investigate survival rates from fracture of endodontically treated posterior teeth (ETT) restored with or without crowns with recall periods of up to 5 years. Methods ETT with single‐unit crown or resin composite restorations were studied based on the inclusion criteria. Restoration, tooth structure loss, adjacent teeth, fracture, and restorability were recorded. Survival rates from fracture were calculated, and risk factors were identified. Results Overall, survival rate of ETT with crowns (92.2%) was significantly higher than resin composites (77.4%) (P < 0.05). ETT with one or two surface loss/es and two adjacent teeth had a high survival rate of 86.9%, which was not significantly different to ETT with crowns (P ≥ 0.05). Restoration and adjacent teeth were identified as significant factors. The majority of fractured ETT with resin composites were restorable, whereas those with crowns were unrestorable. Survival rates from unrestorable fracture were not significantly different between the crown (93.1%) and resin composite (96%) (P ≥ 0.05). Conclusions The survival rate from the fracture of ETT restored with crowns was significantly higher than ETT restored with resin composites, but was not significantly different to ETT with one or two ETT with one or two surface loss/es and two adjacent teeth. ETT restored with resin composites had mostly restorable fracture, whereas ETT with unrestorable fracture were similar between the two restorations.

Clinical performance of direct composite resin versus indirect restorations on endodontically treated posterior teeth: A systematic review and meta-analysis

“…A total of 22 studies met the inclusion criteria, which consisted of 2 RCTs, 16,17 3 prospective, [18][19][20] and 17 retrospective studies. [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] The number of included teeth varied from 57 to 1 462 936 (median 220). Mean follow-up time varied from short term (2 to 5 years) for 13 studies 16,21,23,24,28,29,32,33,35 and medium term (7.3 to 11 years) for 9 studies.…”

“…30,32 Cementation procedure was described in 8 studies: using polycarboxylate, 23,25,35 zinc phosphate, 16,26 glass ionomer, 18,26 or a selfadhesive resin cement. 17,24 A post was used in the restoration of the endodontically treated teeth in 13 studies, varying from 12% to 100% (median 46%) of the restorations. 16,20,22,25,30,32,[34][35][36] For the remaining studies, the proportion of posts was not described.…”

Fracture load of nano-ceramic composite material for anterior endocrown restorations

“…According to restorability, teeth with fractures below CEJ were considered nonrestorable and can't be retreated using the same restorative technique [20]. In the current study, endocrowns specimens were more restorable.…”

Dientes posteriores tratados endodónticamente: Alternativas para su rehabilitación basadas en evidencia científica. Revisión de la literatura

“…Existen dos alternativas para las clases II y III de Peroz (Peroz et al, 2005). La primera consiste en restauraciones de composite, considerando una tasa de supervivencia del 85,5%; no obstante, es fundamental recalcar que existe una mayor incidencia a la fractura (Jirathanyanatt et al, 2019); la segunda hace referencia a restauraciones indirectas de cobertura parcial: inlay, onlay y overlay. Ferrari et al, (2019) efectuaron un seguimiento de 3 años a las restauraciones de dientes posteriores, en los cuales se empleó o no postes de fibra de vidrio e incrustaciones; cuyos resultados se establecen como satisfactorios al exhibir una tasa de supervivencia del 93,3% para premolares y 100% para molares.…”
