Radiographic Assessment of the Technical Quality and Periapical Health of Root-Filled Teeth Performed by General Practitioners in a Turkish Subpopulation

Table 1

Parameters recorded on endodontically treated teeth.

Parameters	Criteria	Definition
Quality of root canal treatments
Length of root canal filling	Adequate	Root filling ending ≤2 mm from the radiographic apex
	Poor	Root filling beyond the radiographic apex or root filling >2 mm from the radiographic apex
Density of root canal filling	Adequate	No voids present in the root filling or between root filling and root canal walls
	Poor	Voids present in the root filling or between root filling and root canal walls
Taper of root canal filling	Adequate	Consistent taper from the apex to the coronal part
	Poor	Not consistent taper from the apex to the coronal part
Periapical status
	Healthy periodontal ligament	If the periodontal ligament was intact with no signs of periapical pathosis
	Apical periodontitis	If the widening of the apical part of the periodontal ligament was not exceeding two times the width of the lateral periodontal ligament space, teeth were catogorized as having widening of the periodontal ligament
	Apical periodontitis	If the periapical radiolucency in connection with the apical part of the tooth exceeding at least two times the width of the lateral part of the periodontal ligament, such teeth were categorized as having obvious periapical radiolucency
Condition of coronal restoration
	Adequate	Any permanent restoration that appeared intact radiographically
	Poor	Any permanent restoration with detectable radiographic signs of overhangs, open margins, or recurrent caries, or presence of temporary coronal restorations
	Missing	No permanent or temporary coronal restoration
