It was discovered that MB2 could be detected by direct observation, using a microscope, CBCT and root canal staining technique by 19.75, 48.15, 79.00, 67.90% respectively. When investigating the correlation of MB2 with the naked eyes and microscope, it showed that the level of the spearman correlation coefficient was in a high to very high level (rs=0.515). Similarly, the correlation between CBCT and root canal staining technique in the coronal and the middle third of root canal presented the high to very high level (rs=0.611, rs=0.523). However, the scales from that of the apical third of root canal was ranging from medium to high level (r=0.479). Mostly, the correlation coefficient level was in the range of the medium to high level (r=0.490). Our results confirmed that the use of microscope to investigate MB2 was significantly more effective than the direct observation. Also, there is no difference between CBCT and root canal staining technique when correlation level of examining MB2 was taken into consideration. Thus, it could be concluded that CBCT was a good clinical tool to be used in the MB2 investigating process.</p>}, number={2}, journal={Khon Kaen University Dental Journal}, author={Anansushatgul, Chayawat and Sutthiprapaporn, Pipop and Osatalert , Busakorn and Waraussawapati , Korkit and Yapanan , Papawadee and Samaksamarn, Thalerngsak}, year={2022}, month={Jul.}, pages={1–13} }
