The characteristics of the denture base surface, in combination with the oral environment, promote the colonization and development of Candida albicans biofilm, which is the main cause of denture stomatitis. This study evaluated the effectiveness of fibrin biopolymer with digluconate chlorhexidine or Punica granatum alcoholic extract to prevent C. albicans biofilm. Conventional heat polymerized and pre-polymerized poly(methyl methacrylate) (PMMA) circular specimens (10 × 2 mm) were fabricated (n = 504) and randomly divided into groups: no treatment (control—CT), fibrin biopolymer coating (FB), fibrin biopolymer with P. granatum (FBPg), or digluconate of chlorhexidine (FBCh) coating. The specimens were inoculated with C. albicans SC5314 (1 × 10⁷ cells/mL) and incubated for 24, 48, and 72 h. Crystal violet and colony-forming unit assays were used to quantify the total biofilm biomass and biofilm-living cells. A qualitative analysis was performed using confocal laser scanning microscopy. Data obtained are expressed as means and standard deviations and were statistically analyzed using a three-way analysis of variance (α = 0.05). The FBPg and FBCh groups inhibited the growth of C. albicans biofilm in both PMMA materials analyzed, with FBCh performing better in all periods evaluated (p < 0.0001). The colony forming unit (CFU) assay showed that the FB group favored the C. albicans biofilm growth at 24 h and 48 h (p < 0.0001), with no differences with CT group at 72 h (p = 0.790). All groups showed an enhancement in biofilm development up to 72 h (p < 0.0001), except the FBCh group (p = 0.100). No statistical differences were found between the PMMA base materials (p > 0.050), except in the FB group (p < 0.0001). Fibrin biopolymer, albeit a scaffold for the growth of C. albicans, when combined with chlorhexidine digluconate or P. granatum, demonstrated excellent performance as a drug delivery system, preventing and controlling the formation of denture biofilm.

Currently, there is no consensus on the indications and clinical performance of implant-supported overdentures (IODs) involving computer-aided design and manufacturing (CAD-CAM) bars.

Objetivo: Avaliar o efeito de três antifúngicos naturais combinados com o cuidado rotineiro com próteses dentárias no tratamento da EP, por meio de uma análise quantitativa de cultura micológica. Métodos: Trinta usuários de próteses dentárias com EP foram tratados com cinco substâncias: água destilada estéril (G1), suspensão oral de nistatina (G2), extrato alcoólico de própolis 20% (G3), gel Punica granatum L. (G4) e gel Uncaria tomentosa (G5). As substâncias foram utilizadas 3 vezes ao dia durante 14 dias. A análise micológica quantitativa das amostras coletadas da mucosa palatina foi realizada em três etapas: antes do tratamento (T0), após 14 dias do tratamento (T1) e 30 dias após o término do tratamento (T2). Os dados foram avaliados pelos testes de Kruskal-Wallis e Friedman (p < 0,05). Resultados: A análise intragrupo da mucosa palatina mostrou uma redução significativa dos valores de Candida UFC/mL para todos os grupos em T1 em comparação com T0 (p < 0,05). No entanto, não apresentaram diferenças estatísticas na comparação de T1 e T2 (p > 0,05). A análise intergrupos demonstrou que não há diferenças estatísticas, independentemente do tempo de avaliação (p > 0,05). Conclusão: Os produtos naturais testados apresentaram resultado satisfatório no tratamento da EP, sendo equivalente à terapia tópica convencional com nistatina e ao tratamento apenas com procedimentos rotineiros de higiene bucal.

Objective: This study evaluated the prevalence, clinical management and sequelae in deciduous teeth involved and permanent successors in 150 children (256 deciduous teeth. Of these, 63.3% were male, 24-35 months of age at the time of the trauma (37.9%) and the falls (78.1%) represented the major etiological factor. In relation to the type of injury, 24.6% was enamel fracture; 62.5% showed support tissue injury (lateral luxation, 22.3%). In the first and second assessments (T1 and T2), the average follow-up time was 14.5 and 26 months (256 and 131 teeth).We diagnosed clinical and radiographic sequels including discoloration of the crown (T1-15.6; T2-13.7%), inflammatory root resorption (T1-7.0; T2-8.4%); and in permanent successors, enamel hypoplasia (T1-1.2; T2-2.3%), eruption disturbances (T1-2.0; T2-1.5%).The chi-square test evidenced association, in T1, between injuries to the supporting tissues and clinical (p = 0.003) and radiographic (p = 0.004) sequelae in permanent successors; and between clinical sequelae and age at the time of trauma (p = 0.005). In T2, radiological sequelae in deciduous teeth with injuries to the tooth and supporting tissue (p = 0.035); as well as clinical sequelae with elapsed time of trauma in permanent teeth (p = 0.005). It is concluded that the follow-up of traumatized deciduous teeth is essential to prevent sequelae.
