ACJ Quiz – Root Canal Treatment X Rays 01

the root canal of tooth # 2.5 is acceptable, and the opacity between two canals is the overlap of the gutta that shows more opaque and seems like a broken file

as the question asks about root canal treatment , furcation perforatio cannot be selected. Underfilled and underinstrument can be selected

the root canal of tooth # 1.7 is acceptable

the distal root is short filled and underextension or underfilled can be selected, also mesial canal is underprepared

mesial canal( in the x ray) is overextension (gutta past the apical foramen) and apical perforation, distal canal (in the x ray) is underinstrumented and underfilled

in the mesial canal the location of the canal is changed

this root canal is acceptable

in the distal canal there is over preparation , over preparation indicate preparing the whole canal or a part of it more than normal.

tooth # 3.6 shows multiple voids in both canals ( voids should be multiple and not in the coronal area)

this root canal treatment is acceptable although there is a small void in it

In the mesial canal there is a spiral instrument that is broken inside the canal.

Under and over preparation are options showing the thickness of the root canal, Underfilled means the incomplete 3D filling of the root canal, under extension is explaining about the length of the root canal

both root canal treatments are considered acceptable

As there is a broken instrument in the canal it means that the canals are not 3D filled with proper material

The root canal of the tooth # 2.6 shows under extension and underfilled, under preparation cannot be selected for this root canal.

the radiopacity seen in the canal is not a broken instrument, broken instruments happen in the apical most part of the root canal when gutta normally cannot pass over it. Here the opacity is the fiber post in the canal.

over extension means that gutta percha past over the apical foramina of the root. For this tooth also apical perforation can be selected

for this root canal voids and under extension and underfilled can be selected

for this tooth the options missed canal, under extension and underfilled can be selected

the options under extension and underfilled can be selected for this root canal treatment, under instrumentation cannot be selected as the canal can be traced

over extension only can be selected for gutta, over preparation only can be selected for the thickness of the root canal, only apical perforation and over instrumentation can be selected

at the tip of both roots sealer puffs can be seen, and the small void at the tip of the distal root is only one and should not be selected. This RCT is acceptable. Successful RCT cannot be selected

for this root canal, over extension and apical perforation can be selected.

in this RCT file is broken and the canal is not prepared beyond the apical point of the file.
