Factors associated with the non-wear of mandibular dentures in the Brazilian public primary health care


Braz. oral res.




Abstract This study investigated factors that affect the use of complete conventional mandibular dentures (CCMD) by patients of the Brazilian Public Health Service. For this, two hundred and thirty one subjects who received CCMD in the Primary Health Care of the Public Health Service in Belo Horizonte – Brazil were evaluated and divided in Group 1 – irregular/non-wear; Group 2 – regular wear. Multivariate logistic regression analysis was used to create predictive models for CCMD non-wear and included socio-demographic and biological variables, technical quality of CCMD, and user satisfaction. The prevalence of CCMD non-wear was 41.10%. The mean score of CCMD quality was 54.97 (0–100). Not wearing the CCMD was significantly associated with user satisfaction and technical quality (p < 0.05). The lack of retention of the CCMD was the most important factor in the evaluation of satisfaction and quality. The final predictive model (specificity = 92.65%; AROC = 0.8759) for not wearing the CCMD retained the variables CCMD stability (OR = 0.888; 95%CI = 0.827–0.954), freeway space (OR = 0.916; 95%CI = 0.860–0.976), satisfaction with speech (OR = 0.694; 95%CI = 0.612–0.786), and irregular CCMD edges (OR = 3.185; 95%CI = 1.478–6.864). Socio-demographic and biological variables were not associated with patients not wearing the CCMD, whereas technical quality and user satisfaction were strongly associated.
