The purpose of this study was to investigate the effect of different chemical intra-oral prosthesis cleansers on the surface properties of Parylene-C coated and non-coated polymethyl methacrylate (PMMA). A total of 120 PMMA samples were prepared. Half of the samples were coated with 10 µm of Parylene-C. Samples were exposed to either air (control) or one of two types of denture cleansers, an alkaline peroxide cleanser (Steradent) or a neutral peroxide cleanser with enzyme (Poligrip). Surface roughness (Ra) and surface free energy (SFE) values were measured and compared between groups. Scanning electron microscopy was used for visual analysis. The samples coated with Parylene exhibited significantly lower mean Ra values compared to the non-coated samples (p<0.001). Immersion in Steradent increased the roughness of non-coated PMMA, but its effect was minimized on the coated surfaces. SFE increased for the samples exposed to air and Poligrip, but decreased for the samples exposed to Steradent.

“…La adherencia del hongo no depende tanto de la polimerización de la resina. Para el caso nuestro no se obtuvo este tipo de asociación (18) Sobre las limitaciones, inicialmente estaba programado el análisis con 20 muestras y solo se pudo realizar el ensayo de adherencia en 12 muestras, lo cual pudo haber interferido con la no obtención de diferencias estadísticamente significativas, en este caso se tendría que aumentar el tamaño de la muestra. El análisis por microscopía electrónica de barrido es una técnica apropiada para valorar la adherencia de microorganismos a diferentes tipos de superficies, así como sus características.…”

Objective: To determine the adherence of Candida albicans to polyamide and acrylic resins. Materials and Methods:In this experimental in vitro study 12 dental prostheses were made, 6 acrylic partial dentures which were elaborated under the heat-curing technique and 6 prosthesis made of polyamide by injection; 2 mm samples with irregular borders were taken from different areas of the prosthesis for analysis and variables such as temperature, heating time, polishing time, material used to shine, presence of porosities, accessory and abrasive used to remove excess were evaluated; the samples were held in distilled water for two days to remove the monomer excess and then they were incubated in a Candida albicans suspension strain ATCC 10231 and evaluated by scanning electron microscopy (SEM). Results: Porosities, cracks, blastospore and pseudohyphae were observed on the resins made from acrylic. The same results were observed on the samples made from polyamide to a lesser extent. Conclusion:Adhesion was found on the 12 samples evaluated. A statistically significant association was found between polishing type and abrasive type with a value of (p <0.05).

“…However, although they are well made and polished, changes can occur over time in the surface of acrylic resin, resulting in microorganism accumulation. In this context, Candida albicans is the fungi more prevalent, difficult to be eliminate and more resistant 20 , and any irregularities in polishing of acrylic resins may allow the irreversible accumulation of cells and microorganism. Proper oral hygiene of the dentures with toothbrush and toothpaste are important factors for the clinical management of the material, and polishing the surfaces of the prosthesis is critical to avoid biofilm accumulation.…”

ObjectiveTo evaluate the effect of aging in a hard denture reline (New Truliner) and an acrylic resin (Classic) ANOVA and Tukey test (α=5%). Results Regardless of the polishing, it was noted that RAC presented significantly higher surface hardness than NT; PM had higher hardness in both materials compared with PQ; on both polishing, the impact resistance of the RAC was higher than NT. Independently of TR test, the impact resistance of the materials that received PQ was higher than received PM. The PQ caused greater changes in properties than the PM. Conclusion Aging and chemical and mechanical polishing influenced the physical and mechanical properties of hard denture reline and acrylic resin.Indexing terms: Acrylic resins. Aging. Denture liners. Hardness. RESUMO ObjetivoAvaliar o efeito da termociclagem em reembasador rígido para próteses totais (New Truliner) e resina acrílica (Clássico) após polimento químico e mecânico. MétodosForam confeccionados 80 corpos de prova, divididos de forma randomizada entre 8 grupos: G 1. Resina Acrílica Clássico (RAC)/Polimento mecânico (PM); G 2. RAC/PM + termociclagem (TR); G 3. RAC/Polimento químico (PQ); G 4. RAC/PQ + TR; G 5. New Truliner (NT)/PM; G 6. NT/PM + TR; G 7. NT/PQ; G 8. NT/PQ + TR. A dureza superficial foi mensurada antes e após os polimentos, e após a TR. Os ensaios de resistência ao impacto foram mensurados após todos os tratamentos. Os dados foram submetidos à análise de variância e Tukey (α=0,05). ResultadosIndependente do polimento verificou-se que RAC apresentou resultados de dureza superficial significativamente mais altos que NT; PM gerou superfícies mais duras em ambos os materiais quando comparado ao PQ; em ambos os polimentos, os valores de resistência ao impacto da RAC foram maiores que os do NT. Independentemente da realização da TR, a resistência ao impacto dos materiais que receberam PQ foi maior que a dos que receberam PM. PQ causou maior alteração nas propriedades do que PM. ConclusãoA termociclagem e os polimentos químico e mecânico influenciam as propriedades físicas e mecânicas do reembasador rígido e da resina acrílica. Termos de indexação:Resinas acrílicas. Envelhecimento. Reembasadores de dentadura. Dureza.

Candida albicans adherence and proliferation on the surface of denture base materials

Abstract: The results obtained from this study indicate that Candida albicans proliferation in particular is not necessarily increased on denture base materials that are subjected to thermal cycling.
