A comparative study of removing two different types of medicaments from root canal during two different periods
Abstract
Aim of study: the aim of this study is to compare removing Calcium hydroxide, Abdullah medicament from root canal.
Materials and Methods: this study was conducted of 30 single canal human teeth. The teeth were collected, root canals were instrumented by standardized technique, the secondary canals were manufactured in apical and middle third of the roots. Then roots were randomly assigned in 2 groups: group A for Ca (OH)2 medicament and group B for Abdullah medicament. medicaments were placed in order to remove them later after 24 hours for group B and 7 days for group A. Then the comparative study was done using X-ray images.
Results: the results showed that Abdullah medicament removal was significantly more effective than the removal of calcium hydroxide paste in both middle and apical third of the root canal.
Conclusion: In the limitation of this study, removal of Abdullah medicament is much easier than removal of Calcium Hydroxide and this affects the success of obturation procedure
هدف الدراسة : الهدف من الدراسة الحالية مقارنة إزالة كل من الضمادات التالية من الأقنية الجذرية : ماءات الكالسيوم، ضماد عبد الله.
المواد والطرق: أُجريت الدراسة على 30 سن بشري وحيد القناة. حُضِّرت الأقنية وفق الطريقة التقليدية. شُفّفت الأسنان وصُنعت أقنية ثانوية في الثلثين الذروي والمتوسط. بعدها قُسمت العيّنة عشوائيّاً إلى مجموعتين: مجموعة A وتم تطبيق ضماد ماءات الكالسيوم فيها لتتم إزالته بعد 7 أيام. ومجموعة B وتم تطبيق ضماد عبد الله فيها لتتم إزالته بعد 24 ساعة. تم تطبيق الضمادات ومن ثم أزيلت بعد مرور الفترة المحدَّدة لكل منها. كما تمت المقارنة فيما بينها باستخدام الأشعة السينية.
النتائج: أظهرت الدراسة سهولة إزالة ضماد عبد الله عند مقارنته مع ضماد ماءات الكالسيوم من الأقنية الثانوية وذلك في الثلث المتوسط والثلث الذروي من جذور الأسنان حيث كانت الفروق ذات دلالات هامة إحصائياً.
الاستنتاجات: ضمن حدود هذه الدراسة تبيّن تفوّق ضماد عبد الله على ضماد ماءات الكالسيوم وهذا الأمر له أهمية كبيرة في نجاح المعالجة اللبية.
