Context: Primary teeth often show bizarre root canal anatomy; this requires the clinician to gain a thorough knowledge of the primary root canal morphology. Complex primary root canal morphology often leads to missed canals, and hence, various strategies can be adapted to reduce this likelihood. Aim: To compare the detection rate and ease of locating root canal orifices in primary molars using magnifying loupes, methylene blue dye, and fluorescein sodium dye. Settings and design: Parallel-arm randomized clinical trial. Materials and methods: A total of 36 primary molars were divided into two groups: Group I: methylene blue; Group II: fluorescein sodium. Both groups utilized magnifying loupes (×2.5). The principal investigator used magnifying loupes, followed by the coinvestigator who used the assigned dye to detect the canal orifices. The principal investigator again examined the dyed canal orifices under magnification. The number of canals found and the ease of locating them with the three different aids were recorded on a five-point Likert scoring scale by both investigators. Statistical analysis: A comparison of the number of canal orifices and ease of location was performed using one-way analysis of variance (ANOVA) and the Kruskal-Wallis test. Results: There was a significant difference in ease of detection between loupes, methylene blue dye, and the loupes combination ( Conclusion: The dye and loupes combination was proven more effective than using dye or loupes alone.
