ABSTRACT
Introduction: When teeth travel horizontally over the sinus floor and their roots extend into the maxillary sinus, they may experience apical root resorption and tipping. Cone-beam computed tomography (CBCT) three-dimensional pictures provide precise, distortion-free data. Before orthodontic treatment and after alignment and levelling, this study used CBCT to assess the connections between the maxillary sinus floor and the apices of the maxillary tooth roots.
Method: Thirty CBCT samples were categorized into two groups:
1. Group I: 15 CBCT scans in the sagittal view, taken before orthodontic treatment and after alignment and leveling.
2. Group II: 15 CBCT scans in the coronal view, taken before orthodontic treatment and after alignment and leveling.
Sagittal and coronal CBCT images were used to thoroughly assess the positional relationships between the inferior wall of the maxillary sinus and the apices of the maxillary tooth roots, including molars and premolars. Measurements of distances were made concurrently in both planes.
Results: Compared to prior orthodontic treatment, CBCT images in the sagittal and coronal planes showed that the roots of posterior teeth protruded substantially more into the maxillary sinus following alignment and leveling.
Conclusion: By helping to forecast the prevalence and severity of root resorption, this study offers important insights for organizing orthodontic tooth movement via the maxillary sinus
Key words: Sagittal plane, maxillary posterior teeth, maxillary sinus, and coronal plane.
