Abstract AR
الهدف : تهدف هذه الدراسة لتقييم تأثير التطهير بالموجات الدقيقة على قوة الانثناء و صلابة السطح لمواد قاعدة الطقم الاكريلية.
المواد وطرق العمل : تم تحضير 112 عينة لدراستها (56 من قاعدة الطقم المتصلبة بطريقة الحمام المائي و 56 تمثل قاعدة الطقم المتصلبة بطريقة الموجات الدقيقة) و بالأبعاد التالية : 56 ± 0.3 * 10 ± 0.03 * 2.5 ± 0.03 ملم لاختبار قوة الانثناء 30 * 15 * ± 0.03 لاختبار صلابة السطوح تم تقسيم العينات إلى 7 مجموعات.
تم تحليل البيانات باستخدام تحليل التباين (الأنوفا) و اختبار دنكن.
النتائج : دل تحليل البيانات المجموعة على وجود فرق معنوي في الانثناء و صلابة السطوح بين المجاميع المدروسة.
الاستنتاجات : أظهرت الدراسة أن مادة الطقم المتصلبة بطريقة الموجات الدقيقة أبدت بعد تعقيمها بالموجات الدقيقة نقصان في مقدار قوة الانثناء و الصلابة إما قاعدة الطقم المتصلبة بطريقة الحمام المائي فأظهرت بعد التعقيم بالموجات الدقيقة زيادة في مقدار قوة الانثناء بينما الصلابة لم تظهر أي فرق معنوي.
Abstract EN
Aims : The aim of this in vitro study was to evaluate the apical sealing ability of matched-taper Single-cone, Thermafil, and Cold lateral condensation obturations.
Materials and Methods : Thirty-six extracted human lower canine teeth were instrumented to size (F3) with ProTaper rotary instruments after cutting of their crowns to the cement-enamel junction CEJ.
The working length was determined for each tooth.
The teeth were divided into (3) groups (10) of each and (6) teeth were used as a positive and negative control groups.
The teeth were obturated with matched-taper Single-cone, Thermafil, and lateral condensation techniques.
Tgadseal was used as a root sealer in this study.
A die penetration method was used to evaluate the apical seal using a stereomicroscope at 40X magnification.
One-way analysis of variance and Duncan's tests were used for statistical analysis.
Results: The statistical analysis of the results demonstrated that there was no statistically significant difference in microleakage between the lateral condensation and Thermafil groups.
The matched taper single cone showed the least microleakage with a significant difference than the other two groups.
Conclusions : The apical sealing ability of Matched-taper Single-cone obturation was better than the lateral condensation and Thermafil techniques when the root canal was prepared using a ProTaper rotary instrumentation.
