摘要

目的:评价和比较添加白色指甲花(WH)和天然指甲花(NH)对白色念珠菌粘附性和义齿基托材料物理性能的影响。材料和方法:243个丙烯酸树脂样品(每组9个)分为抗弯强度试验81个,白色念珠菌粘附试验81个,表面粗糙度、透明度和硬度试验81个。通过添加0.5、1.0、1.5或2.0 wt%的WH或nhh制备热聚合丙烯酸树脂样品。采用直接培养法和载玻片计数法检测白色念珠菌粘附性。弯曲强度、表面粗糙度、硬度和透明度分别采用三点弯曲试验、轮廓仪、维氏硬度试验和分光光度计进行测量。采用方差分析和事后Tukey’s检验进行数据分析。结果:在义齿基托树脂中添加0.5% WH、1% WH和0.5% NH可显著降低白色念珠菌对PMMA义齿基托树脂的粘附(p结论:添加WH和NH可降低白色念珠菌对PMMA义齿基托树脂的粘附。然而,抗弯强度、透明度和表面粗糙度受到不利影响,特别是在较高浓度下。仅用NH可降低硬度。

The in-vitro effects of white henna addition on the Candida albicans adhesion and physical properties of denture base resin.

The in-vitro effects of white henna addition on the Candida albicans adhesion and physical properties of denture base resin.

The in-vitro effects of white henna addition on the Candida albicans adhesion and physical properties of denture base resin.

Purpose: This in-vitro study evaluated and compared the effect of white henna (WH) and natural henna (NH) addition on Candida albicans adhesion and physical properties of the denture base material.

Materials and methods: A total of 243 acrylic resin specimens (9 per group) were divided as follows: 81 for flexural strength, 81 for Candida albicans adherence test, and 81 for surface roughness, translucency, and hardness. Heat-polymerized acrylic resin specimens were prepared by adding 0.5, 1.0, 1.5, or 2.0 wt% of WH or NH. Candida albicans adhesion was determined using direct culture and slide count methods. Flexural strength, surface roughness, hardness, and translucency were measured using the three-point bending test, profilometer, Vickers hardness test, and spectrophotometer, respectively. ANOVA and post hoc Tukey's tests were performed for data analysis.

Results: Addition of 0.5% WH, 1% WH, and 0.5% NH to denture base resin significantly decreased Candida albicans adhesion (p<0.05). WH and NH significantly decreased the flexural strength and translucency, except 0.5% WH, and significantly increased surface roughness, except 0.5% WH and 0.5% NH. WH addition showed nonsignificant differences in the hardness, while NH addition significantly decreased hardness (p<0.05).

Conclusion: Addition of WH and NH decreased C. albicans adhesion to PMMA denture base resin. However, flexural strength, translucency, and surface roughness were adversely affected, particularly at higher concentrations. Hardness was reduced with NH only.
