[Roentgenological evaluation of success of nonvital teeth following treatment with dental post and crown].
For the purpose of a comparative study on the occurrence of periapical changes in non-vital teeth after application of pin crowns, the authors examined radiologically 379 teeth, 175 of which had been apicectomized. The groups of teeth with pin crowns was compared with the group of apicectomized teeth with pin crowns and with a control group of 60 teeth which had only had endodontic treatment. The statistical analysis showed that the group of teeth with pin crowns did not differ significantly from the control group in the occurrence of periapical changes. On the contrary, there was a marked increase in periapical changes in the group of apicectomized teeth with pin crowns compared to the two other groups. This difference was statistically significant.
