The present study aimed at understanding the relationship between periodontitis and socio-contextual and individual determinants of health. Data from "The First Uruguayan Oral Health Survey, 2011", which included 223 and 455 individuals with 35-44 and 65-74 years old respectively, were used. A stratified, multistage cluster sampling design was adopted (cities with ≥ 20.000 residents). Periodontitis was assessed using the modified Community Periodontal Index (CPI) and clinical attachment loss (CAL) (periodontal pocket and CAL ≥ 4 mm). Independent variables included contextual socioeconomic status (SES) measured by proportion of houses with Unsatisfied Basic Needs (UBN) and individual demographic and behavioral factors. Logistic regression multilevel models were generated. Living in contexts with a higher UBN was associated with higher odds for periodontitis in both age groups, even when adjusting for individual level variables (odds ratio [OR] = 1.51, 95%CI = 1.42-1.60 and 1.31, 95%CI = 1.21-1.42, respectively). Being male or heavy smoker increased the odds of periodontitis in this population for both age groups. Social structure impacts periodontal disease by modifying individual socioeconomic situations: in better socioeconomic context, UBN acts increasing the protector role of socioeconomic situation but in a poverty context the role is attenuated. Conclusions for this study are that periodontitis varies across contextual socio-demographic groups being higher in the population with a lower SES, challenging health authorities to integrate oral health into national non-communicable diseases programs.

ObjectivesTo investigate the association between different types of dental prostheses (and residual dentition) and oral health‐related quality of life (OHRQoL).MethodsA population‐based study with a representative sample of adults and older adults in Uruguay (2010‐2011). The dependent variable was the score on the oral impact on daily performance (OIDP), and the main predictor was the pattern of tooth loss and prosthesis use. Covariates included sex, age, socioeconomic status, education, missing teeth, pain and decayed teeth. Negative binomial regression was used.ResultsThe sample comprised 762 participants. Those participants not wearing a prosthesis and with extensive tooth loss had a mean OIDP of 3.1 (95% CI = 1.6‐6.2), while those wearing removable partial dentures (RPD) and having <12 missing teeth had a mean OIDP of 3.6 (95% CI = 1.3‐10.0). Participants with a free‐end saddle had the highest mean OIDP, at 4.9 (95% CI = 2.0‐12.1). For participants with ≤12 missing teeth, any additional missing tooth was associated with an 11% higher OIDP score. Participants who wore RDPs reported fewer impacts on OHRQoL if they had extensive tooth loss or anterior tooth loss than those with a free‐end saddle, or who had lost fewer teeth.ConclusionsThe use of RPDs is associated with better OHRQoL. These findings may be valuable in clinical practice and prosthetic planning.
