The Effect of Tea Tree Oil as a Denture Cleanser on the Surface Roughness of an Acrylic Resin

Objective: This study aims to evaluate the effect of using tea tree oil and chemical agents in den- ture cleaning on the surface roughness of acrylic resin dentures. Methods: A total number of 40 acrylic resin samples (65 mm × 10 mm × 3 mm) were prepared for the study. After the samples were enumerated, their roughness values were determined and they were randomly divided into groups (n = 10) and kept in Protefix, Corega, tea tree oil, and distilled water. The time period for the immersion in the solutions was established as 20 minutes. The roughness values were measured again after 720 immersions. The data thus obtained were evalu- ated using two-way analysis varinace and post hoc Tukey's test. Results: As a result of the variance analysis, it was determined that the liquid used and the immer- sion time were not statistically significant (P > .05). Conclusions: It is exciting that natural oils have an important place in people’s lives in all aspects and that we can use them in denture cleansing. The surface roughness of base materials is impor- tant for both aesthetics and microbiology. Dentists have to consider the effects of tea tree oil on the surface roughness of base material. Keywords: Acrylic resin, denture cleaners, surface roughness, tea tree oil ÖZ Amaç: Bu çalışma, protez temizliğinde çay ağacı yağı ve kimyasal ajanların kullanılmasının akrilik rezinin yüzey pürüzlülüğüne etkisini değerlendirmeyi amaçlamaktadır. Yöntemler: Çalışma için toplam 40 adet akrilik rezin (65 mm x 10 mm x 3 mm) hazırlandı. Numuneler numaralandırıldıktan sonra pürüzlülük değerleri belirlenmiş ve rastgele gruplara (n=10) ayrılarak Protefix, Corega, çay ağacı yağı, distile suda bekletilmiştir. Çözeltilere daldırma süresi 20 dakika olarak belirlendi. 720 daldırma işleminden sonra pürüzlülük değerleri tekrar ölçülmüştür. Elde edi- len veriler, iki yönlü ANOVA ve post-hoc Tukey testi kullanılarak değerlendirildi. Bulgular: Varyans analizi sonucunda kullanılan sıvının ve daldırma süresinin istatistiksel olarak anlamlı olmadığı belirlendi (P > ,05). Sonuç: Doğal yağların insanların hayatında her yönden önemli bir yere sahip olması ve bunları protez temizliğinde kullanabilmemiz heyecan verici. Temel malzemelerin yüzey pürüzlülüğü hem estetik hem de mikrobiyoloji için önemlidir. Diş hekimleri, çay ağacı yağının temel materyalin yüzey pürüzlülüğü üzerindeki etkilerini dikkate almalıdır. Anahtar Kelimeler: Akrilik rezin, protez temizleyiciler, yüzey pürüzlülüğü, çay ağacı yağı
