Prevalence and quality of endodontic treatment in an elderly urban population of Switzerland.
Little oral health data on the elderly are available in Switzerland. This study assessed endodontic findings in 66-yr-old residents of the city of Zurich using intraoral radiographs. Of the 143 volunteers having a total of 2004 natural teeth, 78% had at least one endodontically treated tooth. Twenty percent of all teeth were root filled, two thirds of them being in the upper jaw. Sixty-four percent of the root fillings were judged insufficient and 8.5% of all teeth showed periapical radiolucencies, most of the latter (73%) being associated with insufficient root canal treatments. Ninety-eight percent of the root-filled teeth had intracanal retentive devices. Fifty-two percent of the teeth with insufficient root fillings were judged not to need revision, 37% needed revision, 9% needed apicectomy, and 2% were ready for extraction. The considerable endodontic treatment needs of the elderly can only be reduced by an improvement of quality of initial endodontic treatment.
