Summary:
Purpose:
To evaluate the quality of both root fillings and coronal restorations, using radiographic and clinical criteria, as related to the prevalence of PARL in a Belgian subpopulation.
Materials and Methods:
– Root-filled teeth were selected on panoramic radiographs of randomly selected patients attending the
Dental School. Teeth that were not tx by the preceding year were included.
– All PA radiographs were evaluated using an X-ray viewer with 5x magnification by 2 calibrated examiners. The coronal restoration, the presence of a post in the canal, the RCT and the PA conditions were scored according
to the criteria listed in Table 1.
– Teeth were divided to 4 grps: Gp.A: good endo and good coronal resto Gp.B: poor endo and good resto; Gp.C: good endo and poor coronal resto; Gp.D: poor endo and poor coronal resto.
Most Highlighted Results:
– 745 teeth were scored clinically and radiographically.
-Gp,A ( good endo with good resto) had 22.5% of AP and Gp.B (poor endo with good resto) had a 34.4% of AP with a sig diff between both grps.
-Gp.C had a 24.3% AP and Gp.D had a 43.2% of AP with a sig diff between both grps.
-Gp.D and Gp.A had a sig diff.
-Homogeneity and length of RC filling, presence of a base, and the radiographic appearance of coronal restoration sig affected the percentage of AP.
Clinical Significance:
Coronal leakage may not be of such clinical impact as indicated by previous studies, provided endodontic treatment procedures are carefully carried out.
