“…La capa más externa de la pared celular de Candida albicans consta de un complejo de polisacáridos principalmente Manán, Glucán y Quitina, además de proteínas y una proporción variable de lípidos, los cuales están involucrados en la adhesión a las células del huésped, así como a las propiedades antigénicas (12).…”

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).

A Review of Water‐Resistant Hemicellulose‐Based Materials: Processing and Applications

Hemicelluloses, due to their hydrophilic nature, may tend to be overlooked as a component in water-resistant product applications. However, their domains of use can be greatly expanded by chemical derivatization. Research in which hydrophobic derivatives of hemicelluloses or combinations of hemicelluloses with hydrophobic materials are used with to prepare films and composites is considered herein. Isolation methods that have been used to separate hemicellulose from biomass are also reviewed. Finally, the most useful pathways to change the hydrophilic character of hemicelluloses to hydrophobic are reviewed. In this way, the water resistance can be increased and applications of targeted water-resistant hemicellulose developed. Several applications of these materials are discussed.

“…Os diferentes graus de inflamação palatal, que podem ocorrer como resultado do uso de próteses, são normalmente associados a presença de um grande número de micro-organismos do gênero Candida no espaço entre a mucosa que recobre o palato e a superfície da prótese [11,36,40], sendo assim as próteses funcionam como um reservatório onde estes micro-organismos se proliferam causando a infecção [43,44].…”

“…ao acrílico [42,44,45], ao fluxo de saliva reduzido sob as superfícies da prótese, à má adaptação das próteses totais, ao uso noturno e à deficiência na higiene oral [3,11,36]. As superfícies ásperas das próteses, especialmente na região que recobre o palato, tendem a favorecer o desenvolvimento do biofilme uma vez que nestas superfícies é mais difícil a eliminação de micro-organismos.…”

Departamento de Prótese pela oportunidade de realizar esta pesquisa.Ao programa de pós-graduação da FOUSP-Ciências Odontológicas, na pessoa do Prof. Dr. Marcelo Bonecker.À Profa. Dra. Tomie Toyota de Campos, minha orientadora. Obrigada pelas palavras de incentivo, pela confiança e por seu olhar encorajador.Ao Prof. Dr. Atlas Edson Moleros Nakamae, obrigada por ver em mim, lá no projeto Bandeira Científica, um potencial que nem eu sabia que tinha. Obrigada por todo conhecimento transmitido, por toda a confiança, oportunidade e amizade. Você me ensinou não só Odontologia e Ciência, mas lições para toda a vida. A Deus, pois sua força e sabedoria me abriram os olhos para a ciência.Aos meus pais pelo amor incondicional, pelo incentivo e pelo apoio, inclusive financeiro, para que este projeto fosse realizado.Ao meu marido Raphael, pela paciência, pela ajuda e apoio, por acreditar em mim, me incentivar e me encorajar, mesmo nos momentos mais difíceis. Obrigada pela estatística e pelas traduções. À Erika, por ser meu braço direito, e às vezes o esquerdo também! Obrigada por tudo que resolveu por mim neste período. Sem sua ajuda seria muito difícil.A toda minha Família, Guerreiros e Aldarvis, por compreenderem com tanto carinho a minha ausência em tantos almoços, jantares e viagens neste período.A todos que contribuíram para a execução deste trabalho, meu MUITO OBRIGADA! however this mechanism could not be highlighted as the responsible for the inhibition observed. The coaggregation indexes showed correlation coefficients of r = 0.5 with the microorganisms inhibition capacity. There has been intensive organic acid production in cultures and co-cultures, according to the present lactobacilli strain.Candida presence did not alter the lactobacilli UFC count, whereas the lactobacilli presence caused reduction in Candida count, especially C. albicans and C. dubliniensis. The growth curves and pH showed that the behavior of co-cultures is similar to the lactobacilli cultures. The pH analysis showed that acidification occurred for all cultures; nevertheless, L. rhamnosus has promoted a greater acidification. We concluded that lactic acid is the most important mechanism among the studied ones, being capable of reducing UFC count and shifting the growth curves for C. albicans and C. dubliniensis. Furthermore, we concluded that the inhibition occurs through multiple factors that may vary according to the present yeast and lactobacilli species.
