Tissue conditioner is used to condition inflamed mucosa induced by denture stomatitis. However, the drawback of the aging tissue conditioner is increased surface roughness, thus enhance microbial adhesion. Ocimum basilicum is known for its antimicrobial effects but its use in liners has not been investigated. Aims: This study aimed to determine the antifungal efficacy of ocimum basilicum essential oil (OBEO) when incorporated into tissue conditioner against C. albicans and the effect on the properties.
The antimicrobial activities were determined using disc diffusion, minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC). After incorporation into tissue conditioner, the color difference and surface roughness were evaluated after one day. The surface morphology and the antibiofilm activity were assessed on day 1 and day 14.
The zone of inhibition of OBEO on Sabouraud Dextrose agar was significantly wider than nystatin and deionized water (=0.000) with the MIC and MFC values were 1.25% and 5%. Both OBEO concentrations incorporated into tissue conditioner, there was no significant difference of color changes in the light-dark character (=0.102) and surface roughness (=0.920) when compared to the control group. As for adherence at days 1 and 14, both concentrations of OBEO in tissue conditioner show significantly reduced adherence of C. albicans compared to the control group (=0.000).
OBEO exhibited significantly better antifungal activity against C. albicans when compared to nystatin and deionized water and resulted in no significant color changes, better surface roughness and lesser adherence of C. albicans toward the tissue conditioner.
组织调理剂用于调理由义齿性口炎引起的炎症黏膜。然而,老化的组织调理剂的缺点是表面粗糙度增加,从而增强微生物黏附。罗勒因具有抗菌作用而闻名,但其在衬垫中的应用尚未得到研究。目的:本研究旨在确定罗勒精油(OBEO)加入组织调理剂后对白色念珠菌的抗真菌效果及其对性能的影响。
采用纸片扩散法、最低抑菌浓度(MIC)和最低杀菌浓度(MFC)测定抗菌活性。加入组织调理剂后,一天后评估色差和表面粗糙度。在第1天和第14天评估表面形态和抗生物膜活性。
OBEO在沙氏葡萄糖琼脂上的抑菌圈明显比制霉菌素和去离子水宽(P=0.000),MIC和MFC值分别为1.25%和5%。与对照组相比,两种OBEO浓度加入组织调理剂后,在明暗特性(P=0.102)和表面粗糙度(P=0.920)方面颜色变化无显著差异。至于第1天和第14天的黏附情况,组织调理剂中两种浓度的OBEO与对照组相比,白色念珠菌的黏附均显著降低(P=0.000)。
与制霉菌素和去离子水相比,OBEO对白色念珠菌表现出明显更好的抗真菌活性,且不会导致显著的颜色变化,具有更好的表面粗糙度,白色念珠菌对组织调理剂的黏附也更少。
