Abstract
Background and objectives: Considering the proximity of the roots of maxillary molars to the maxillary sinus floor (MSF) and their sensitivity to odontogenic and non-odontogenic lesions, this study aimed to show the relationship between the roots of maxillary molars and the MSF using cone beam computed tomography (CBCT).
Materials and methods: This cross-sectional study included the CBCT images of 148 fully erupted maxillary molar teeth. The evaluation included the vertical relationship between the maxillary molar and the MSF, the angle of divergence between the apex of the molar roots and the thickness of the cortex of the MSF, and the distance between the apex of the molar roots and the MSF. All parameters were analyzed by sex and age. Data were analyzed using SPSS version 22. A P-value less than 0.05 was considered statistically significant.
Results: The most frequent type of vertical relationship included the lack of root contact with the sinus border and the presence of the MSF cross-section above the root apex (type I), which was significantly more common among women than men. The highest angular deviation among the three molar roots was observed in the first molar, and the angle of divergence between the buccal (B) and palatal (P) roots was greater than the angle between the B roots.
Conclusion: Based on the results of this study, the roots of the maxillary molars are far from the MSF in most cases, and the greatest divergence of the roots is related to the first molar, and this tooth should be extracted cautiously.
