Quality-shaping factors in endodontic treatments (Study II, IV-VI)
There is a marked discrepancy between the outcome of root canal treatments
reported in clinical controlled studies performed by specialists in endodontics
(Strindberg 1956, Petersson et al. 1982) or by dental students (Kerekes & Tronstad,
1979, Sjogren et al. 1990), compared to the estimated outcome found on the basis of
epidemiological studies among GDPs
(review: Eriksen et al. 2002). In most
populations, a high frequency of technically defective root fillings, a high prevalence
of periapical radiolucencies in root-filled teeth, and a strong correlation between the
two is demonstrated (Bergenholtz et al. 1973, Allard & Palmqvist 1986, Eckerbom et
al. 1987, Odesjti et al. 1990, Petersson et al. 1986, Eriksen et al. 1988, Imfeld 1991,
De Gleen et al. 1993, Buckley & Spangberg 1995, Saunders et al. 1997, De Moor et
al. 2000, Kirkevang et al. 2001, Boucher et al. 2002, Lupi-Pegurier et al. 2002,
Dugas et al. 2003, Loftus et al. 2005, Ridell et al. 2006).
