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

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.

Impacto da regeneração por biomateriais no tratamento de recessões periodontais / Impact of regeneration using biomaterials in the treatment

O tratamento das recessões periodontais tem sido motivo de estudos nasúltimas décadas. As técnicas cirúrgicas clássicas apresentam significativorecobrimento radicular e a regeneração tecidual guiada, associada aos biomateriais,tem sido sugerida como promotora de regeneração do periodontode inserção perdido. O objetivo do presente estudo foi, por meio derevisão da literatura, avaliar às técnicas de avanço coronal do retalho e daregeneração tecidual guiada associada à membrana bioabsorvível de colágenoe o fosfato de cálcio bifásico no tratamento das recessões periodontais.Os resultados obtidos nessa revisão sugerem que os procedimentosde avanço coronal do retalho e o protocolo de regeneração periodontalpromovem o recobrimento radicular, sendo que o avanço coronal do retalhoapresentou melhores resultados quanto aos parâmetros clínicos de alturade gengiva ceratinizada e percentual de recobrimento radicular, sem,entretanto, sugerir formação de novo cemento, ligamento periodontal eosso alveolar. Mais estudos longitudinais são necessários para avaliar o impactodas membranas e dos substitutos ósseos no recobrimento radiculare no ganho do periodonto de inserção.
