Influence of melaleuca and copaiba oils on Candida albicans adhesion

Abstract

Our results demonstrated that M. alternifolia oil inhibited the growth of C. albicans. Moreover, both oils promoted significant adhesion reduction in the tested strains. These findings suggest the possibility of using these oils in prophylaxes against candidiasis.

Development of antibacterial denture cleaner for brushing containing tea tree and lemongrass essential oils

“…The results of the present study show that TO and LO have antifungal effects against C. albicans, which has also been reported in other studies 11,[14][15][16][17][18][19] . However, LO were more effective than TO based on the MIC and MBC values, and consider that the differences in antifungal effect were related to the individual components of the essential oils.…”

“…In 2004, the Scientific Committee on Consumer Products in Brussels, Belgium stated that 80-90% of the contents of M. alternifolia oil are monoterpenes 23) , which is consistent with the TO used in our study [terpinen-4ol (41.90%), γ-terpinene (20.30%), α-terpinene (9.30%), 1.8-cineole (3.2%), para-cymene (2.80%), α-terpineol (2.90%), α-pinene (2.40%), terpinolene (3.30%), limonene (1.00%), sabinene (0.20%); 87.30% of total composition]. Another report also noted that TO showed a MIC of 0.375% towards C. albicans strain ATCC10231 18) . We found that the effect of this oil was caused by its higher density due to the difference in content of terpene related to its growth environment or place of origin.…”

“…Dalwai et al reported that TO was more effective against Candida growth inhibition on heat cured resin as compared to fluconazole 17) . Tobouti et al noted that Candida have difficulty with surface adhesion following immersion in Melaleuca alternifolia oil 18) . There are also other reports describing inhibition of biofilm formation by plant essential oils, while ours is the first to show a removal effect.…”

“…Furthermore, several studies have reported that both TO and LO reduced biofilm formation on denture surface resin, and suggested their use for denture cleaning [17][18][19] . However, in clinical situations, many dentures with attached biofilm already developed are washed, though few reports have focused on removal of surface biofilm by use of an essential oil.…”

Avaliação dos efeitos adversos de soluções desinfetantes nas propriedades físicas e mecânicas de materiais para confecção de próteses totais

“…O método químico consiste na imersão da prótese em substâncias químicas com diferentes componentes e mecanismos de ação com objetivo de desorganizar o biofilme e causar a morte dos microrganismos. Vários são os estudos clínicos e laboratoriais que avaliam os efeitos dessas soluções sobre as propriedades físicas e mecânicas da resina acrílica de base, dentes artificiais, reembasadores para próteses totais e metais, bem como a capacidade de remoção de biofilme e atividade antimicrobiana (Davi et al, 2012;Pellizaro et al, 2012;Altieri et al, 2013;Rodrigues et al, 2013;Savabi et al, 2013;Vasconcellos et al, 2013;Al-Saadi, 2014;Amin et al, 2014;Freire et al, 2014;Kurtulmus-Yilmaz;Deniz, 2014;Oliveira et al, 2014;Paranhos et al, 2014;Salloum, 2014;Sczepanski et al, 2014;Tobouti et al, 2016;Yildirim-Bicer et al, 2014;Amin et al, 2015;Arruda et al, 2015;De Souza Porta et al, 2015;Gama et al, 2015;Haghi et al, 2015;Jeyapalan et al, 2015;Neppelenbroek et al, 2015;Panariello et al, 2015;Rodrigues Acosta et al, 2015;Salles et al, 2015;Sorgini et al, 2015;Badaró et al, 2016;Pero et al, 2016;Basavana et al, 2016;Matos et al, 2016). Porém, pode-se verificar a utilização de diferentes períodos de imersão diária e a avaliação dos efeitos destas soluções em um período curto de tempo, não representando a realidade clínica de uso das próteses.…”
