Variables | Score |
---|---|
Clinical and radiographic quality of coronal restorations | 0: Anatomical restoration with no open margins, no overhangs, and no recurrent decay (Adequate) |
1: Restoration with overhangs (Inadequate) | |
2: Restoration with open margin (Inadequate) | |
3: Restoration with unsatisfactory anatomic form (Inadequate) | |
4: Restoration with recurrent decay (Inadequate) | |
5: Fractured, detached, or lost restoration (Inadequate) | |
6: tooth cusp or tooth wall fracture (Inadequate) | |
Radiographic quality of root canal filling | |
Length of the root filling | 0: root filling ending from 0 to 2Â mm short of the radiographic apex (adequate) |
1: root filling ending more than 2Â mm short of the radiographic apex, unfilled canals, detectable void between the intra-radicular post and the filling material (inadequate) | |
2: filling extruded beyond the apex (inadequate) | |
Homogeneity of the root filling | 0: root canal filling with good radiographic density, no detectable voids between filling material and root canal walls (adequate) |
1: root canal filling with low radiographic density, detectable voids (inadequate) | |
Conicity of root canal filling | 0: continuously tapering funneled preparation from the canal orifice to the apex, and cross-sectional diameter narrower at every point apically (adequate) |
1: inconsistant taper from the coronal to the apical part of the filling, or root filling deviated from the original canal (inadequate) |
