Table 1 Parameters for classification.

➢	Tooth number
➢	Presence/absence of previous RCF
➢	Presence/absence of AP according to CBCTPAI score proposed by Estrela et al [] of tooth with previous RCF⁶
➢	Presence/absence of broken instruments
➢	Extension of RCF (classified as: “short” when more than 2 mm short of the radiographic apex; “flush” when filled within 0–2 mm of the radiographic apex; and “long” when extended beyond the radiographic apex)
➢	Homogeneity of RCF (classified as: “homogeneous” when RCF presented no voids; ‘nonhomogeneous’ when RCF presented voids, poor density)
➢	Presence/absence of ledge formation
➢	Presence/absence of perforation
➢	Presence/absence of missed canals
RCF – root canal filling; AP – apical periodontitis; CBCT PAI – cone beam computed tomography periapical index.
