f2-dent04_p0012: On the millimetric glass scale, measurements were made to characterize the geometrical location of MB2 canals. MB: mesiobuccal canal orifice, MB2: second mesiobuccal canal orifice, P: palatal canal orifice.

Mentions: To categorize the canal system in MBR (mesiobuccal root) mesio-distal and bucco-palatal radiographs were obtained. The size 0.8 files were placed into the main mesiobuccal and second mesiobuccal canal. The teeth with no access to the apex were eliminated. Before photographing of pulp chambers millimetric glass scale was placed in order to make measurements to characterize the geometrical location of MB2 canals. The main mesiobuccal, palatal and MB2 canal orifices were marked on the millimetric glass scale. The main mesiobuccal canal and the palatal orifices were connected through a line MB-P and in addition to this line a perpendicular line was drawn from the MB2 canal orifice to the M-P line. The main mesiobuccal canal was accepted as the origin and the vertical distance from MB2 to MB-P line was measured, as described by Görduysus et al16 (Figure 2). The images were analyzed by Image-Proplus 4.0 software to measure the relationship between MB2 canal and other canals.

The Location and Accessibility of the Second Mesiobuccal Canal in Maxillary First Molar

Tuncer AK, Haznedaroglu F, Sert S - Eur J Dent (2010)

Bottom Line: With the unaided vision, 58 MB2 canal orifices and after evaluation with the dental loup, DOM an additional 28 MB2 canal orifices were detected.In 65 molars, the MB2 canal orifices was located 0.87 mm distally and 1.73 mm palatally to the main mesiobuccal canal and in the remaining 21 molars was 0.72 mm mesially and 1.86 mm palatally.Presence of second mesiobuccal canal was similar to the other studies but in a Turkish sub-population it originates mainly distal to the main MB canal.

ABSTRACT

Objectives: The purpose of this study was to examine the location and accessibility of the second mesibuccal canal in maxillary first molar of a Turkish sub-population.

Methods: Presence and accessibility of the MB2 canal in 110 extracted maxillary first molars was examined with unaided vision, dental loups and the DOM. To characterize the geometrical location of MB2 canals, photographs of pulp chambers were obtained.

Results: With the unaided vision, 58 MB2 canal orifices and after evaluation with the dental loup, DOM an additional 28 MB2 canal orifices were detected. In 65 molars, the MB2 canal orifices was located 0.87 mm distally and 1.73 mm palatally to the main mesiobuccal canal and in the remaining 21 molars was 0.72 mm mesially and 1.86 mm palatally.

Conclusions: Presence of second mesiobuccal canal was similar to the other studies but in a Turkish sub-population it originates mainly distal to the main MB canal.
