Resin composites have become the first choice for direct posterior restorations and are increasingly popular among clinicians and patients in comparision to amalgam. When evaluating direct restorations, generally clinical variables and characteristics related to materials and operators have been focused. On the other hand, studies investigating the influence of factors related to patients are very rare and most of them were carried out in university clinical settings, with a lack of population-based data. This study aimed to evaluate posterior restorations placed in young adults, investigating the association between determinants experienced during the life course and two posterior restorations outcomes: the quality of tooth fillings and the dentists choice of restorative material. In addition, we reviewed the dental literature looking for clinical trials investigating posterior composite restorations over periods of at least 5 years of follow-up published between 1996 and 2011 to investigate the longevity of composite restorations in this studies and factors that influence restorations failures.A representative sample (n = 720) of all 5,914 births occurring in Pelotas in 1982 were prospectively investigated, and posterior restorations were assessed at 24 yr-old. Exploratory variables included demographic and socioeconomic, oral health and service utilization patterns during the lifecourse. Tooth related variables (type of tooth, material, size of cavity) were also analysed. Multilevel Logistic Regression models were used to determine factors associated with restoration outcomes. Failures in posterior restorations showed a significant association with socioeconomic (income trajectory from birth to age 23), clinical (presence of dental caries at age 15) and tooth-related variables (size of cavity). On the other hand, dentists choice for amalgam as posterior restorative material was associated with type of payment of dental services (health insurance vs. private), higher presence of dental caries at age 24, type of tooth (molars vs. premolars) and size of cavity. These results suggest that, although tooth-related variables have an important role in the investigated restorations outcomes, patient-related factors, such as socioeconomic and oral health variables, are also associated with these conditions and should take in account when evaluating posterior restorations
