Abstract

Aim: This cross-sectional study evaluated the anatomical relationship between maxillary molar roots (MMRs) and the maxillary sinus floor (MSF) in Libyan adults, assessing demographic influences. Methods: CBCT images from 102 patients (408 molars; 1,224 roots) were analyzed. Root-MSG relationships were classified as: Class I (apex below MSF), Class II (apex contacting MSF), and Class III (apex protruding into sinus)

Results: Distribution: Class I (42%, n=517), and Class II (37%, n=446), Class III (21%, n=261). Prev alence: Class I: Highest in MB roots of first molars (left: 56.9%; right: 52%), Class II: Dominant in DB roots of second molars (left: 49%; right: 48%), and Class III: Most frequent in MB roots of second molars (left: 32.4%; right: 34.3%). There was Significant associations with younger age and male gender (p<0.05).

Conclusion: Maxillary second molars' buccal roots demonstrate the closest MSF proximity, with higher intrusion risks in males and younger patients. CBCT assessment is recommended for treatment planning.
