Comparison of Maxillary Molar Roots with Maxillary Sinus in High-resolution CBCT: A Retrospective Study.

BACKGROUND

The maxillary sinus is a pyramidal-shaped osseous cavity, and maxillary molars are found to be in close proximity to the sinus floor or even protruding into it. The present study was conducted to measure the relation between the roots and sinus floor and also the thickness of the bone using CBCT to determine age and gender differences.

MATERIALS AND

METHODS

The individuals were separated into two groups based on age: Those under 40 and those over 40 years. There were 25 men and 25 females in the study. Axial, coronal, and sagittal slices of the CBCT images were obtained.

RESULTS

The first molar root distance and cortical bone thickness varied significantly between men and women, as well as across different ages. Mesiobuccal root with sinus floor was shown to have a substantial mean value for both sexes (P = 0.049 and P = 0.003). In females, the thickness of the buccal plate was 1.291 mm, whereas, in men, it was 2.447 mm (P = 0.000). There was a substantial difference in the thickness of the buccal plate between men and women who were at least 40 years old (P = 0.000).

CONCLUSION

This study suggests how important it is to look at anatomical features and bone thickness when determining a person's age and gender.
