A Microcomputed Tomographic Evaluation of Root Canal Morphology of Maxillary Second Premolars in a Pakistani Cohort

This study aimed to investigate variations in the root canal morphology of maxillary second premolar (MSP) teeth using microcomputed tomography (micro-CT). Sixty (N = 60) human extracted MSPs were collected and prepared for micro-CT scanning. The duration scanning a single sample ranged between 30 40 min three-dimensional (3-D) image was obtained all MSPs. images evaluated by observer who recorded type, number roots, orifices, apical foramina(s), delta(s), accessory canals. configuration categorized agreement with Vertucci’s classification, any not classification reported as an “additional configuration”. Descriptive statistics (such mean percentages) calculated SPSS software. most common types agreeing (in order highest lowest incidence) I, III, V, VII, II, VI. also exhibited four additional configurations that different from classification: 2-3, 1-2-3, 2-1-2-1, 1-2-1-3. A found 96.7% majority samples demonstrated two canals (73.3%). Further, 80% showed one orifice. foramina’s variable, 56.7% having solitary foramen. 33.3%, delta only 20% samples. Variable detected our study. prevalent type 1; however, results revealed some types.
