This study analyzed the root and canal configurations of maxillary premolars in a Jordanian subpopulation using cone-beam computed tomography (CBCT) and classified them based on Vertucci’s and Ahmed’s systems.
Methods
Two hundred CBCT scans of 800 maxillary premolars were retrospectively assessed for root morphology, canal configurations, and root canal divergence and merging. Data was statistically analyzed.
Results
The study included 70 males and 130 females. Most right and left maxillary first premolars (RFPM, LFPM) had two roots (59.0% and 58.5%), with a significant association between sex and root number for RFPM and LFPM (p < 0.05). In contrast, the right and left maxillary second premolars (RSPM, LSPM) mostly had a single root (87.5% and 88.5%), with no association with sex. Vertucci’s classification showed type IV as the predominant configuration in first premolars (RFPM, 65.0% and LFPM, 67.0%) and type I in second premolars (RSPM, 44.0% and LSPM, 49.0%). A significant sex association was found only with RSPM. Ahmed’s classification revealed that maxillary premolar with two separated roots and two separated canals (2MP B1 P1) was mostly found in first premolars (RFPM, 58.0% and LFPM, 56.0%), and maxillary premolar with one root and one canal (1MP1) in second premolars (RSPM, 44.0% and LSPM, 49.0%), with a significant sex association for RSPM and LSPM (p < 0.05). Age had no impact, and symmetry was observed between the right and left sides. Three-rooted premolars were identified in four cases. Almost all of Vertucci’s types and numerous codes from Ahmed’s classification were documented.
Conclusions
CBCT revealed diverse anatomical variations in the Jordanian subpopulation, with Ahmed’s classification providing more detailed canal configurations than Vertucci’s, uncovering previously overlooked variations.
