تعمل أطقم الأسنان النظيفة على تعزيز صحة المريض، وطول عمر طقم الأسنان، ونوعية الحياة العامة عن طريق منع التلوث المتبادل. يجب ألا يؤدي أسلوب التنظيف الفعال إلى إتلاف المواد الأساسية للطقم. تبحث هذه الدراسة في صلابة وامتصاص الأشعة فوق البنفسجية وامتصاص الماء وقابلية ذوبان راتنج الأكريليك المعالج بالحرارة بعد 180 مرة من الغمر في منظف طقم الأسنان بزيت شجرة الشاي. تم إجراء تسعين عينة من راتينج الأكريليك المعالج بالحرارة وتقسيمها إلى ثلاث مجموعات. تتكون كل مجموعة من 30 عينة موزعة على ثلاث مجموعات مغمورة في (المجموعة الأولى: ماء مقطر، المجموعة الثانية: زيت شجرة الشاي 0.75%، المجموعة الثالثة: زيت شجرة الشاي 1%)، بإجمالي 10 عينات لكل مجموعة. تم غمر العينات لمدة 10 دقائق وفقًا لمجموعاتها لمدة 180 مرة. بعد ذلك، تم فحص العينات لمعرفة صلابة السطح، وامتصاص الأشعة فوق البنفسجية، وامتصاص الماء، والذوبان. بعد الغمر لمدة 180 مرة، أظهرت محاليل زيت شجرة الشاي اختلافات غير معنوية (P > 0.05) في صلابة السطح، وتحسن كبير إحصائيًا عن طريق تقليل امتصاص الأشعة فوق البنفسجية، وامتصاص الماء والذوبان (P <0.05). أظهر راتينج الأكريليك المعالج بالحرارة المغمور 180 مرة أن تركيز زيت شجرة الشاي بنسبة 0.75% يحسن قابلية الذوبان وامتصاص الماء ولكن لا صلابة السطح ولا امتصاص الأشعة فوق البنفسجية، في حين أن تركيز زيت شجرة الشاي بنسبة 1% يعزز امتصاص الماء والذوبان وامتصاص الأشعة فوق البنفسجية ولكنه لا يؤثر على الصلابة.
