#تعديلات
التعديلات أصبحت كثيرة😅..
في الدائرة المحددة باللون البنفسجي 💜فيه تعديل بسيط وهو:
عدد ال Cusp ridge هو 17 وليس 18
يعني بيكون بعد التعديل كذا 👇
"21 ridges 17 of them are cusp ridge"
#التشريح_الوصفي_للأسنان_٢_نظري

In general!
Maxillary molars have ( 3_ 5) cusps
3 or 4 or 5
Mandibular molars have ( 4_5) cusps
4 or 5
رسمات الدكتور لل Occlusal surface في جميع الاسنان الخلفية خاصة المولارز مهمة جدا من حيث مواضع وحجم ال cusp tips والتضيق و الميول . أذا طلب نرسم رسمة يفترض ان تكون مشابهه تماما خاصة في حدود السن من الخارج.
بالتوفيق للجميع

النص الذي محدد غليه بدائرة خضراء 💚
بنعدل فيه اسم ال Cusp
M.P ----> D.P
يعني بيكون النص بعد التعديل كذا👇
"2- Ridges:(Palatal cusp ridge of D.P cusp, Distal cusp ridge of D.P cusp, Mesial cusp ridge of D.P cusp, and Triangular cusp ridge of D.P cuSp )"
