Preoperative imaging for lower third molar removal often lacks strong scientific evidence. Panoramic and intraoral radiographs are usually sufficient, with advanced imaging reserved for complex cases involving the mandibular canal.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Radiology
Background:
- Preoperative imaging is crucial for planning lower third molar removal.
- Current scientific evidence supporting specific imaging techniques is limited.
Purpose of the Study:
- To critically review the role of radiographic imaging before lower third molar removal.
- To propose a preoperative imaging strategy based on evidence and clinical experience.
Main Methods:
- Systematic literature search of Medline database using keywords 'third molar' and 'radiography'.
- Inclusion of original articles and reviews, supplemented by reference lists.
- Integration of scientific literature with authors' clinical expertise.
Main Results:
- Scientific evidence for the utility of various preoperative imaging techniques for wisdom teeth is low.
- Panoramic and/or intraoral radiographs are adequate in most cases without mandibular canal overlap.
- Posteroanterior open mouth projection can resolve many remaining cases.
- Volume tomography (CBCT, LDCT) is indicated for cases with intimate mandibular canal-wisdom tooth relationship.
Conclusions:
- A practical preoperative imaging strategy for lower third molars is proposed.
- Standard radiography suffices for routine cases, while advanced imaging is reserved for complex anatomical relationships.
- The strategy aims to optimize diagnostic yield and resource utilization in third molar surgery planning.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
