ABSTRACT
ABSTRACT Objective:
To determine in vitro the frequency, shape, type, diameter, and patency of accessory canals in the primary molars pulp chamber floor. Material andMethods:
Sixteen healthy primary molars were evaluated by micro-computed tomography and scanning electron microscopy. Descriptive analyses of the frequency, shape (round, oval, or irregular), type (blind, true, or hidden), patency and diameter of the accessory canals were performed.Results:
Half of the teeth presented accessory canals, 62.5% of which were located in the upper molars and 37.5% in the lower molars. The most frequent shape was irregular. In three-dimensional analysis, blind accessory canals (12.5%) and with patency (18.7%) of the teeth were observed. The average accessory canal diameter was 51.97 µm (± 26.03 µm).Conclusion:
Upper molars showed a higher frequency of accessory canals with larger diameters. The irregular shape was the most frequent. 18.7% of accessory channels showed patency.Key words
