In total, 306 posterior composite restorations placed in 44 adult patients were investigated after 10 to 18 yrs. The history of each restoration was extracted from the dental records, and a clinical evaluation was performed with those still in situ. The patient risk status was assessed for caries and \u201cocclusal-stress\u201d (bruxism-related). Statistical analysis was performed by the Kaplan\u2013Meier method and Cox-regression multivariate analysis. In total, 30% of the restorations failed, of which 82% were found in patients with 1 or 2 risk factors. Secondary caries was the main reason of failure within caries-risk patients, whereas fracture was the main reason in \u201cocclusal-stress-risk\u201d patients. The patient variables gender and age did not significantly affect survival, but risk did ( p &lt; .001). Tooth type ( p &lt; .001), arch ( p = .013), and pulpal vitality ( p = .003) significantly affected restoration survival. Within the limits of this retrospective evaluation, the survival of restorations is affected by patient risk factors, which should be included in survival analyses of restorations.<\/jats:p>","DOI":"10.1177\/0022034513484337","type":"journal-article","created":{"date-parts":[[2013,5,21]],"date-time":"2013-05-21T00:57:07Z","timestamp":1369097827000},"page":"S78-S83","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":174,"title":["Patient
