Three of these teeth contained bacteria of the species Sundqvist et aI. 89 Although there were a small number of teeth that contained bacteria at the time of root filling, there was a statistically significant difference (p = 0.033) in success rates between the teeth that had yielded positive bacteriologic samples at the time of root filling (33%) and those that had not (80%).

Study design: Six teeth that had conventional root canal treatment or re-treatment with nonresolving periapical radiolucencies underwent periapical surgery. Biopsies were obtained and analyzed descriptively by correlative light and transmission electron … The tooth and the adjacent field were decontaminated with a 2.5% sodium hypochlorite for 30 s each and then inactivated with 5% sodium thiosulfate.

root canal micro-flora in teeth with apical periodontitis is very diverse, although comprising mostly anaerobic micro-organisms (Sundqvist 1992, Dahle´n & Haapasa- Correspondence: Dr R.J.G. De Moor, Department of Operative lo 1998, Munson et al. 2002).

Efter disputationen erhöll han först post doc-anställning (1992) och sedan lektorat (1997) i STS vid dåvarande Institutionen för tvärvetenskapliga studier vid Göteborgs universitet. The teeth tx with 1 -step showed 3 times the failure rate as those previously opened for emergency treatment. The higher failure rates of those teeth presenting with apical periodontitis may serve as contraindication for 1 -step NSRCT. • Bystrom & Sundqvist (1981): One steps do not remove bacteria in nec rotic cases.

The existence of commensal or antagonistic relationships between microorganisms in the root canals of teeth with apical periodontitis was investigated. thirteen teeth without periapical lesions (Sundqvist 1976). In a well-controlled monkey experiment in which the pulps of twenty-six teeth were rendered necrotic under sterile conditions and immediately sealed in the uninfected root canals, none developed apical periodontitis, even after 6-7 months of observation.
