323 Patienten, die in 1993 eine Praxis in Stuttgart aufsuchten, wurden röntgenologisch untersucht. 2.7% der vorhandenen Zähne waren wurzelbehandelt. 61% dieser Zähne wiesen röntgenologisch pathologische periapikale Befunde auf. Nur 14 % der Wurzelfüllungen konnten im Bezug auf Dichte und Länge als technisch einwandfrei bezeichnet werden.

treatment needs in an urban German population.

The objective of this study was to determine the periapical status and the
quality of root canal fillings and to estimate the endodontic treatment
needs in a German population. Clinical and radiographic data and the
operative procedures performed were evaluated on 323 patients coming to a
dental surgery in Stuttgart, Germany, in 1993. In 182 individuals at least
one tooth exhibited a root canal filling, a necrotic pulp or an
irreversible pulpitis. Out of the 7897 teeth examined, 215 (2.7%) had a
root canal treatment (category A), 122 being non-endodontically treated
(1.5%) did not respond to the sensitivity test (category B) and 53 (0.7%)
were diagnosed as having irreversible inflamed pulp tissue (category C).
The prevalence of teeth associated with radiographic signs of periapical
pathosis was 61% in the group of root canal filled teeth and 88% in the
group of pulpless and non-endodontically treated teeth. Using the level and
the density of the root canal filling as criteria for evaluating the
technical standard, only 14% of the endodontic treatments of
non-apicectomized teeth were qualified as adequate. The minimal endodontic
treatment need is 2.3% related to all examined teeth when the root canal
filled teeth with clinical symptoms of periapical periodontitis (category
A) and those of categories B and C are included. The real endodontic
treatment need is suggested to be larger when considering that the
technical quality of the obturation is poor in most symptomless
endodontically treated teeth associated with a periapical lesion. In the
case of retreatment of these teeth, the endodontic treatment need would
then be calculated at 3.7%.
