Dental Restoration Longevity among Geriatric and Special Needs Patients

Introduction:Although the population is aging and retaining more teeth, there is a lack of studies that address the longevity of dental restorations placed among older adults.Objectives:This study aimed to describe the survival trajectory of dental restorations placed in an outpatient population of geriatric and adult special needs patients over a 15-y span, with particular interest in the longevity of subsequent restorations in teeth that received multiple restorations over time.Methods:Dental restorations of different types and sizes in patients aged ≥65 y treated between 2000 and 2014 at the University of Iowa College of Dentistry were followed until they incurred an event (i.e., restoration replacement, extraction of the tooth, or endodontic treatment of the tooth). Survival analysis and extended Cox regression models were used to generate hazard ratios for selected predictor variables.Results and Conclusion:A total of 9,184 restorations were followed among 1,551 unique patients.
