简要总结
A clinical study will be conducted to verify the reliability of the root form classification of impacted lower third molars that was put by Abu-Mostafa N (2023) The root forms of partially or fully impacted lower third molars will be classified pre-operatively based on panoramic radiograph, then clinically after extraction, and the identified root classifications will be compared.
详细描述
According to Abu-Mostafa N, the roots of impacted lower third molars are classified into two types: Fused roots and separated roots. Both have different forms:
Fused roots forms: Straight, Curved distal, Curved mesial, and S-shaped.
Separated roots forms: Straight, Both roots are curved distal, Both roots are curved mesial, Joined roots, One root is straight and one is curved, and More than two roots.
A panoramic radiograph will be taken before extraction, then the roots will be classified by two Oral biologist and Oral and Maxillofacial Surgeon individually. After surgical extraction of the third molar, the roots will be examined clinically and classified according to the same classification.
The two pre-extraction radiographic classifications will be compared together, and then they will be compared with the clinical classification to check if there is a discrepancy.
