Abstract
Aim: This study aims to evaluate the antifungal properties of Thymus vulgaris (thyme) essential oil (TVEO) on Candida albicans-infested polymethyl methacrylate (PMMA) denture base materials and identify the volatile components of T. vulgaris essential oil.
Materials and Methods: The investigation involved establishing C. albicans's presence on resin surfaces manufactured in 1x1x0.1 cm size. The resin surfaces on which the C. albicans biofilm had formed were then soaked in a 2% and 5% solution of TVEO and the effect on the amount of C. albicans colonisation were evaluated. The volatile components of TVEO were determined using the GC-MS method.
Results: Solutions prepared from 2% and 5% TVEO showed better antifungal activity than Corega. The major components detected by GC-MS in the TVEO were carvone 61.36%, linalool 8.32%.
Conclusion: TVEO, showed significant antifungal effects on PMMA resin surfaces. This oil can, therefore, be recommended as an inexpensive, uncomplicated and efficient natural cleaning agent for those wearing dentures.

Abstract
Amaç: Bu çalışmanın amacı Candida albicans tutulumu sağlanmış polimetil metakrilat (PMMA) protez kaide materyallerine Thymus vulgaris (kekik) esansiyel yağının (TVEO) antifungal etkisini değerlendirmek ve TVEO’nun uçucu bileşenlerini belirlemektir.
Gereç ve Yöntem: Çalışmada ilk olarak 1x1x0,1 cm boyutunda hazırlanan rezin yüzeylerine C. albicans tutulumu sağlandı. Daha sonra rezin yüzeyleri, TVEO’dan hazırlanan %2 ve %5 oranındaki solüsyonunda bekletilerek C. albicans kolonizasyonundaki değişiklik değerlendirildi. TVEO’nun uçucu bileşenleri GC-MS yöntemi ile belirlendi.
Bulgular: TVEO’dan %2 ve %5 oranında hazırlanan solüsyonlar Corega’ya göre daha iyi antifungal aktivite gösterdi. TVEO’da GC-MS ile tespit edilen majör bileşenler carvone %61,36, linalol %8,32.
Sonuç: TVEO, PMMA rezin yüzeylerinde etkili antifungal aktivite gösterdi. Protez kullanıcıları için alternatif, ucuz, basit ve etkili bir doğal temizleyici olarak önerilebilir.
