“…These results agreed with those of Abed (2022), who found a nonsignificant difference in acrylic roughness after immersion in electrolyzed water (37) . Heidrich et al (2018) obtained the same results, that was, rosemary and castor oils and propolis extract had no damaging effect on the surface roughness of pink acrylic resin until the fourth month (38) . Similarly, Salman and Saleem (2011) demonstrated that when the heat acrylic resin was immersed in different denture cleaner solutions, the resin's surface was not affected (39) .…”

Background: Denture cleansing was an important step that could prevent the spread of infection and improve a patient's health, the durability of the dentures, and the overall quality of life; therefore, it was necessary to choose a suitable cleanser that, in addition to being effective, did not have an unfavorable effect on the qualities of the denture base resin itself when used for an extended period. For this purpose, this study aimed to evaluate the effect of tea tree oil (TTO) on Candida albicans adhesion and the surface roughness property of poly(methyl methacrylate) denture material after immersion in TTO. Methods: A total of 55 heat-cured acrylic resin specimens were used for C. albicans adherence and surface roughness tests. They were distributed into groups (0.25%, 0.5%, 0.75%, and 1%) of TTO, distilled water (DW), and 2% clorhexidine digluconate, totaling five specimens for each group. The specimens were immersed in accordance with their group for 10 minutes. Surface roughness was determined by a profilometer, and C. albicans adherence was determined by measuring optical density with a spectrophotometer. For comparisons between groups for surface roughness and disinfection tests, one-way ANOVA was performed on SPSS program, considering α = 0.05. Results: TTO had a statistically significant effect on C. albicans adhesion to heat-cured acrylic resin (P < 0.05) compared with negative control. Meanwhile, no statistically significant difference was found between 0.75% and 1% TTO concentrations (P > 0.05), whereas the surface roughness test showed a statistically non-significant difference between TTO concentrations and DW (P > 0.05). Conclusions: Immersion of acrylic resin in TTO was effective in decreasing C. albicans adhesion to it, and the greatest decrease was obtained by 1% TTO. The surface roughness test showed a non-significant difference in acrylic roughness after immersion in TTO.

“…Apesar do HS1% ser uma solução química com propriedade branqueadora, neste estudo, ele não foi capaz de alterar a coloração da resina acrílica. Estudo anterior (Heidrich et al, 2018) encontraram alteração de cor em todos os grupos de seu estudo quando espécimes de resina acrílica eram imersos em outros extratos (óleo de rícino, óleo de alecrim, extrato glicólico de própolis), bem como em água destilada e hipoclorito de sódio, porém por maior período de tempo que neste trabalho. Nossos diferentes achados podem se relacionar com o menor tempo de imersão utilizado e o fenômeno de sorção de água que a resina acrílica apresenta quando imersa em água por longos períodos (Fernandes et al, 2011).…”

Este estudo investigou a ação do extrato hidroalcoóde Arrabidaea chica (AchE) contra C. albicans, bem como seu efeito na citotoxicidade em fibroblastos e queratinócitos e alterações nas propriedades físico/mecânicas de resina de PMMA. A susceptibilidade da C. albicans ao AchE foi avaliada por meio da CIM e CFM. Para os testes de suscetibilidade, biofilmes de C. albicans foram desenvolvidos em disco de resina acrílica de PMMA por 48 horas e imersos em 5 grupos, tampão fosfato-salino, hipoclorito de sódio 1% ou em AchE na CIM, 5xCIM ou 10xCIM. A citotoxicidade do AchE (10, 50 e 100 µg/m) em fibroblastos e queratinócitos foi avaliada pelo método MTT sendo a água destilada e NaOCl l% utilizados como controles. Para avaliação das propriedades físico/mecânicas (rugosidade superficial, alteração de cor e resistência flexural), discos foram imersos nos 5 grupos já descritos. Os discos foram incubados e os testes foram realizados após 0, 7, 14, 21 e 28 dias de imersão. O AcHE foi considerado um forte inibidor e com potencial bactericida. A 10 µg/mL não apresentou citotoxicidade, comparando-se ao grupo controle. Demais grupos experimentais foram citotóxicos, porém, com valores menores quando comparados ao NaOCl 1%. Não houve diferenças significativas nas propriedades físico/mecânicas independente do grupo ou tempo avaliados. O AchE, quando utilizado em altas concentrações, foi citotóxico em células fibroblastos e queratinócitos e, independente das concentrações utilizadas, não interferiu nas propriedades físico/mecânicas das resinas PMMA.

“…In this sense, biopolymers of plant origin have been used for developing products to the biomedical field, including polyurethane [3][4][5][6][7][8] . Polyurethane from castor oil is a compound that consists of a prepolymer and a polyol extracted from the seed oil of the Ricinus communis plant, which does not exude toxic vapors and is a biocompatible material [9,10] .…”

Surface and micromechanical analysis of polyurethane plates with hydroxyapatite for bone structure

et al. 2022

To analyze the surface topography and mechanical properties of a polyurethane derived from castor oil reinforced with hydroxyapatite (PU-HA) for bone fixation. The surface analysis was performed by Scanning Electron Microscopy (SEM) and the mechanical properties by Vickers microhardness and tensile tests. The SEM images showed that the PU surface presented important characteristics for materials intended for bone fixation, such as an irregular and porous surface. The analysis showed a surface with alternating areas with depressions and elevations of approximately 80±100 µm, presence of pores of 12 µm in size. The microhardness analysis showed values of 0.42±1.01 HV for PU-HA plates, lower in relation to the poly lactic-co-glycolic acid (PLGA) plate (control group). The elastic modulus and ultimate tensile strength of 317.4 MPa, and 35.57 MPa for PLGA sample, 1.187 MPa, and 0.29 MPa for PU-HA sample. The PU produced showed good surface properties, however demands better mechanical properties.
