التغيرات الكيسية المرافقة للرحى الثالثة السفلية البازغة جزئياً ( المنحصرة)
Abstract
إن موضوع الإنطمار، وشذوذات بزوغ الأسنان هو موضوع مهم للغاية، حيث يشكل مرضى الإنطمار السني نسبة عالية من مراجعي أطباء جراحة الوجه والفكين، وبالأخص مرضى انطمار الرحى الثالثة السفلية نظراً لكثرة الاختلاطات التي تسببها مثل النخور، امتصاص جذور الأسنان المجاورة، التراكب، الكسور الفكية، التواج، الأكياس.
أجريت هذه الدراسة بهدف دراسة التغيرات الكيسية المرافقة للبزوغ الجزئي للرحى الثالثة السفلية وعلاقة هذه التغيرات بعمر، وجنس المريض.
تم إجراء دراسة نسيجية على عينة مؤلفة من 113 حالة انطمار جزئي للرحى الثالثة السفلية، والتي كان المرضى فيها يعانون من تاريخ إصابة بالتواج حولها، وذلك عند 113 مريضاً (61 ذكراً, 52 أنثى) توزعت أعمارهم بين (18-41) سنة, تم أخذ خزعة من محتويات الجيب اللثوي، والعظمي المتشكل حول الرحى، وذلك بعد القلع الجراحي لها.
أظهرت نتائج الفحص النسيجي أن هناك تغيرات كيسية التهابية (غير تطورية) حول الرحى الثالثة المنحصرة تتناسب شدتها طرداً مع تقدم العمر، ووصلت إلى مرحلة الكيسة الصريحة بنسبة بلغت (3.5%), ولم يظهر أي تأثير لجنس المريض على ظهور هذه التغيرات
The topic of impaction and abnormal eruption of teeth is very important, because the patients who have impacted teeth form the most of those who need the maxillofacial surgery care, specially the patients who have impacted mandibular third molars because of its complications as carries, resorption of adjacent teeth roots, teeth crowding, jaw fractures, pericoronitis, and cysts.
This study is done to evaluate the cystic changes that associated with partial eruption of mandibular third molars and its relation with age and sex of patient.
A histolological study was done to (113) patients who have (113) partially impacted mandibular third molar cases ( impacted), and the patients were suffer of pericoronitis around molars.
The total sample was divided into males and females as following (61) males and (53) females. The patients ages ranged between (18-41) years. We took a biopsy from gingival and bone pocket contents that developed around the impacted molar, and we took the biopsy during extracted the impacted molar surgically.
The result shows inflammatory cystic changes (non developmental) around the impacted molar, and these changes were in different stages of the mature, in addition the mature stage was congruous with advancing of age, and it reached to the cyst stage in low rate which was (3.5%).
Also, we didn’t note any effect to patients sex on appearance of cystic changes.
