Abstract
Statement of problem
After endodontic treatment, teeth may require additional treatment. Data regarding
the number of treatments up to extraction after endodontic treatment are lacking.
Purpose
The purpose of this retrospective study was to evaluate the number of consecutive
restorative procedures performed on a specific tooth starting from endodontic treatment
up to extraction. A comparison was made between crowned and uncrowned teeth.
Material and methods
A retrospective study was conducted using 28 years of data from a private clinic.
The total number of patients was 18 082 and included 88 388 treated teeth. The data
were collected for permanent teeth that received at least 2 consecutive retreatments.
The data included tooth number, procedure type, date of procedure, total number of
procedures conducted during the study period, extraction date, time from endodontic
treatment to extraction, and whether the tooth had been crowned or not. Endodontically
treated teeth were divided into 2 groups: extracted and nonextracted. In each group,
a comparison was made between crowned and uncrowned teeth and between anterior and
posterior teeth by using the Student t test (α=.05).
Results
In the non extracted group, teeth that were crowned required significantly (P<.05) fewer restorative treatments (mean ±standard deviation 2.9 ±2.1) than uncrowned
teeth (5.01 ±2.98). For extracted teeth, the mean time from endodontic treatment until
extraction was 10.39 years. Crowned teeth were extracted after a mean of 11.06 years
and 3.98 treatments, while uncrowned teeth were extracted after a mean of 9.96 years
and 7.22 treatments (P<.05).
Conclusions
Endodontically treated teeth that were crowned required significantly fewer subsequent
restorative procedures than uncrowned teeth and exhibited higher survival rates up
to extraction.
