Application of two systems to classify the root and canal morphology in the human dentition: A national survey in India

Abstract

AbstractPurposeTo assess the application and accuracy of two systems (Vertucci et al. 1974 and Ahmed et al. 2017) in classifying the root and canal morphology of human dentition among final‐year undergraduates, interns, and postgraduate dental students in India.MethodsThe survey was conducted using physical and online presentation modes in two phases. Phase 1; PowerPoint presentation (PPT), describing the most used classification system (Vertucci et al. 1974) and its supplementary types and Ahmed et al. (2017) classification. A single presenter delivered the PPT to participants, using either a projector in an auditorium/seminar hall (face‐to‐face) or an online platform (zoom meeting software). Phase 2 involved determining the students’ responses. A questionnaire was distributed amongst the participants after the lecture and collected for analysis. Fisher's exact test was used to analyze the data statistically, and the significance level was set at 0.05 (p < 0.05).ResultsA total of 1082 participants were involved in this survey. Overall, 93% of study participants found that Ahmed et al. classification system was more practical and accurate than Vertucci et al. system and its supplemental configurations (p < 0.001). About 97% agreed that Ahmed et al. classification system aided in understanding root and canal morphology better than Vertucci's and its additional configurations, and they recommended to include in their curriculum (p < 0.001).ConclusionsIn comparison to Vertucci's classification system and supplementary types, the undergraduate and postgraduate dental students, and interns in India agreed that Ahmed et al. classification system is more practical and accurate for classifying the root and canal morphology.
