WebOct 10, 2024 · The maximum incidence of file fracture was observed in the canals with >25° curvatures (57% of the total file fractures). The present study results are in accordance with those of the past literature where severely curved canals tend to show more file fractures than the straight canals. [21] WebAug 3, 2024 · The incidence rate of fractured rotary NiTi instruments varies greatly according to the type of instrument (brand, size, taper, cross-sectional shape, and instrument design), the assessment of fracture incidence, the operator, the methodology used, and several other variables that differ among the experimental works. iphone free apps download
