Abstract

Purpose: To evaluate the effect of adding tea tree oil to denture liners on Candida albicans and bond strength to the acrylic denture base.

Materials and methods: Disc-shaped specimens were fabricated from silicone-based resilient liner (Tokuyama, Molloplast), acrylic-based hard liner (GC Reline), and acrylic-based soft liner (Visco-gel). Tea tree oil (TTO) was incorporated into the liners at varying concentrations (0% [control], 2%, 5%, 8%). C albicans were counted by viable colony count, and optical density (OD) was measured with a spectrophotometer. The tensile strength to heat polymerized acrylic denture base was measured in a universal testing machine. The compliance of the data to the distribution of normality was evaluated using the Shapiro Wilk test. Two-way ANOVA, Bonferroni correction, and paired sample t test were performed (α = .05).

Results: The addition of TTO into liners provided a significant decrease in the OD values (P < .001). The control groups of the liners presented the highest colony counts, whereas increasing TTO decreased the results (P < .01). According to tensile bond strength test, 8% TTO addition resulted in a significant decrease for Tokuyama (P < .01) and Molloplast liners (P < .05), while 2% TTO resulted in significance for GC Reline (P < .001).

Conclusions: Denture liners containing increasing percentages of TTO presented lower amounts of C albicans colonies and decreased bond strength to the denture bases. When using TTO for its antifungal properties, the amount added should be carefully selected because the tensile bond strength may be affected.

茶树油添加到义齿衬垫中对白色念珠菌和丙烯酸义齿基托结合强度的影响。

目的：本体外研究的目的是评估茶树油在义齿衬垫中对白色念珠菌的影响以及与丙烯酸义齿基托的结合强度。材料和方法：由硅树脂基弹性衬垫（Tokuyama，Molloplast）、丙烯酸基硬衬垫（GC Reline）和丙烯酸基软衬垫（Visco gel）制成圆盘状试样，并将茶树油以不同浓度（0%-对照，2%，5%，8%）掺入衬垫中。用活菌落计数法计数白色念珠菌，用分光光度计测定光密度。在通用试验机上测量了热聚合丙烯酸义齿基托的拉伸强度。使用Shapiro-Wilk检验评估数据与正态分布的符合性。双向方差分析、Bonferroni校正，进行配对样本t检验（α=0.05）。结果：将茶树油添加到衬垫中可显著降低OD值（p）结论：含茶树油的义齿衬片，随着添加量的增加，白色念珠菌菌落数减少，与义齿基托的结合强度降低，在使用茶树油的抗真菌活性时，应谨慎选择添加量，因为添加量可能会影响抗张结合强度。

期刊介绍： Official Journal of the European Association for Osseointegration (EAO), the International College of Prosthodontists (ICP), the German Society of Prosthodontics and Dental Materials Science (DGPro), and the Italian Academy of Prosthetic Dentistry (AIOP) Prosthodontics demands a clinical research emphasis on patient- and dentist-mediated concerns in the management of oral rehabilitation needs. It is about making and implementing the best clinical decisions to enhance patients'' quality of life via applied biologic architecture - a role that far exceeds that of traditional prosthetic dentistry, with its emphasis on materials and techniques. The International Journal of Prosthodontics is dedicated to exploring and developing this conceptual shift in the role of today''s prosthodontist, clinician, and educator alike. The editorial board is composed of a distinguished team of leading international scholars.
