“…, Kirkevang et al . ), only AP at baseline was found to be significantly negatively associated with tooth survival in the present study. However, when the endodontic variables were studied separately in relation to tooth survival using the chi‐square test, teeth diagnosed with completely filled root canals and those diagnosed with normal periapical status at baseline survived significantly more often than incompletely filled teeth and root filled teeth with AP.…”

“…Similar findings were reported in a Danish study: at the 10‐year follow‐up, the periapical condition of 50% of the teeth registered at baseline as root filled remained sound (Kirkevang et al . ). Excluding the teeth that were retreated, a lower proportion (37%) of the teeth registered at baseline as root filled remained in sound periapical condition after 20 years.…”

Aim To study the 20-year survival rate and periapical status of root-filled teeth in a Swedish population requiring high cost dental care and to identify factors related to survival and normal periapical status at follow-up.Methodology The study population comprised 104 patients selected from four local health insurance districts with treatment plans including radiographs submitted for approval for reimbursement from the Swedish National Dental Insurance in 1977. In 1998 a clinical and radiographic follow-up examination was conducted, to register the status of 449 teeth identified as root-filled at baseline. Differences in tooth survival and periapical status at follow-up, with reference to periapical status and quality of root-filling at baseline were analyzed by Chi-square tests. Multiple regression analysis was used to describe tooth survival and normal periapical status at followup, with the explanatory baseline variables: tooth type, type of restoration, type of post, quality of root-filling, periapical status, marginal bone loss and caries.Differences were considered significant at a 5% level.Results Two hundred and ninety (65 %) of the root-filled teeth survived at follow-up Baseline variables associated with low odds for tooth survival were mandibular molar, maxillary premolar, prefabricated posts other than screw-posts, severe marginal bone loss, caries and apical periodontitis (AP).Normal periapical status at follow-up was registered in 49 % of the rootfilled teeth. Baseline variables associated with low odds for normal periapical status (high risk for AP) at follow-up were mandibular molar, maxillary premolar, AP, severe marginal bone loss and inadequate root-filling quality. Of the root-filled teeth with AP 3 at baseline 42 % had been left untreated during the observation period and at followup the AP persisted in 57 % of these teeth. ConclusionsAfter 20 years 65 % of the root-filled teeth had survived and one third remained in sound periapical conditions, without any further treatment. Almost half of the APs registered at baseline were left without treatment and more than half of them persisted after 20 years.
