Table 1

Assessment of root canal treatment outcome according to the European Society of Endodontology [29].

Outcome	Clinical findings	Radiographic findings		Recall period
Favorable	(i) Absence of pain, swelling, sinus tract, loss of function, and other symptoms	Initial	Recall	At least one year
		(i) Normal periodontal space around the root	(i) Periodontal space unchanged
		(ii) Radiolucent area	(ii) Healing of the lesion with normal periodontal space around the root
Uncertain		(i) Radiolucent area	(i) No changes in the size of the initial lesion	At least after 4 years
Unfavorable	(i) Presence of pain, swelling, sinus tract, loss of function, and other symptoms	(i) Periodontal space remained normal after endodontic treatment	(i) Radiolucent area	Further treatments are required
	(ii) Presence of signs of root resorption	(ii) Radiolucent area	(i) ^aAbsence of healing: radiolucent area remained the same, increased, or diminished in size during the 4-year assessment period

^aFor an extensive radiological lesion, the tooth should be further assessed, because the lesion may heal but form a scar tissue.
