Failure was defined as the need for replacement of at least one surface of the original restoration or extraction of the tooth. Individual-, tooth-, and restoration-related factors were obtained from dental records. Five-year mean annual failure rate (mAFR) and median survival time were calculated (Kaplan-Meier statistics). The effect of potential risk factors on failure was tested using univariate log-rank tests and multivariate Cox-regression analysis (α = 5%).\r\nResults: A total of 728 restorations in 101 patients were included in the analysis. The survival after 5 years amounted to 67.7% (5-year mAFR: 7.5%) and median survival time to 7.9 years. Results of the multivariate Cox-regression analysis revealed physical disability (HR: 50.932, p = 0.001) and combined intellectual/physical disability (HR: 3.145, p = 0.016) compared with intellectual disability only, presence of a removable partial denture (HR: 3.013, p < 0.001), and restorations in incisors (HR: 2.281, p = 0.013) or molars (HR: 1.693, p = 0.017) compared with premolars to increase the risk for failure.\r\nConclusion: Composite restorations placed under general anesthesia in adult patients with intellectual and/or physical disabilities showed a reasonable longevity as 67.7% survived at least 5 years.\r\nClinical relevance: Survival of composite restorations depends on risk factors that need to be considered when planning restorative treatment in patients with intellectual and/or physical disabilities.

Survival (no further intervention) and failure (removal, loss or replacement of crown, replacement of access restoration, or recementation of restoration) of crowns and retainers with repaired endodontic access cavities were recorded. The mean annual failure rates were calculated, and the effect of individual-, tooth-, and restoration-related variables on survival was assessed by univariate log-rank tests and multivariate Cox regression analyses with shared frailty (P < .05).\r\nResults: One hundred eighty repaired crowns/retainers placed in 151 patients were included (4.5 ± 3.3 years follow-up). Survival after 2, 5, 7, and 10 years amounted to 82.7%, 71.5%, 67.3%, and 48.8% (mean annual failure rate = 9.0%, 6.5%, 5.5%, and 6.9%), respectively. Although tooth type, kind of restoration, endodontic irrigant, repair conditioning methods, and kind of composite affected survival in the univariate regression analyses, only the kind of restoration (single crown vs retainer restoration) remained significant in the multivariate Cox regression model.\r\nConclusions: Repairing endodontic access cavities with composite increases the longevity of single crowns and retainer restorations."],["dc.identifier.doi","10.1016/j.joen.2019.11.012"],["dc.identifier.pmid","31980200"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/65679"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/65641"],["dc.language.iso","en"],["dc.relation.eissn","1878-3554"],["dc.relation.issn","0099-2399"],["dc.relation.orgunit","Poliklinik für Präventive Zahnmedizin, Parodontologie und Kariologie"],["dc.subject.gro","Composite"],["dc.subject.gro","endodontic treatment"],["dc.subject.gro","repair"],["dc.subject.gro","retreatment"],["dc.subject.gro","survival"],["dc.title","Effect of Repairing Endodontic Access Cavities on Survival of Single Crowns and Retainer Restorations"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
