Species-specific polymerase chain reaction (PCR) was also performed to detect Enterococcus faecalis and Candida albicans. Bacterial DNA was detected in all samples. Twenty of the 28 taxon-specific probes tested were reactive with at least one sample.

Only eight taxa were present at levels > 10(5). Of these, streptococci and T. denticola were the most prevalent. Species-specific PCR detected E faecalis in 47% of the cases and C albicans in 6%. Findings of this study confirm the strong association between persistent/secondary intraradicular infection and posttreatment apical periodontitis.

All removal attempts were performed using an operating microscope and ultrasonic tips using a technique described by Ruddle (2003). Results Of the 170 fractured instruments, 162 could be removed without perforation of the root canal, corresponding to a success rate of 95%. At a failure rate of 5%, eight instruments could not be removed, with root wall perforation occurring in one case. The lowest success rate of 93% was found in maxillary molars, the highest success rate of 100% in maxillary premolars and anterior and canine teeth of the maxillary and mandibular jaw. All removal failures occurred in cases where the fractured instruments were located apically or in the middle and apical part of the root. Regarding the angle of root canal curvature, the lowest success rates were found between 21 degrees and 50 degrees. Conclusions The position of the instrument within the root canal, the angle of the curvature of the root canal and the location of the fractured instrument in relation to the root canal curvature were the decisive factors that had a negative influence on the treatment outcome.The removal method tested represents a highly effective technique for the retrival of fractured instruments."],["dc.identifier.doi","10.1111/j.1365-2591.2009.01652.x"],["dc.identifier.isi","000278566500001"],["dc.identifier.pmid","20456518"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/19532"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","0143-2885"],["dc.relation.orgunit","Poliklinik für Präventive Zahnmedizin, Parodontologie und Kariologie"],["dc.title","The outcome of retained instrument removal in a specialist practice"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

None of the techniques had a significant effect on cleaning the lateral grooves. Within the limitations of this study protocol ultrasonic irrigation shows a superior effect on sealer removal from the root canal surface during endodontic retreatment.

Although this neuronal network has attracted great attention for studying neuronal aspects of synaptic transmission, functions of glial cells supporting this neuronal activity remain unclear. To investigate the role of astrocytes in the respiratory network, we applied electrophysiological and immunohistochemical techniques to characterize astrocytes in regions involved in the generation and transmission of rhythmic activity. In the ventral respiratory group and the hypoglossal nucleus (XII) of acutely isolated brainstem slices, we analyzed fluorescently labeled astrocytes obtained from TgN(GFAP-EGFP) transgenic mice with the whole-cell voltage-clamp technique. Three subpopulations of astrocytes could be discerned by their distinct membrane current profiles. A first group of astrocytes was characterized by nonrectifying, symmetrical and voltage-independent potassium currents and a robust glutamate transporter response to D-aspartate. A second group of astrocytes showed additional A-type potassium currents, whereas a third group, identified by immunolabeling for the glial progenitor marker NG2, expressed outwardly rectifying potassium currents, smaller potassium inward currents, and only minimal D-aspartate-induced transporter currents. Astrocytes of all groups showed kainate-induced inward currents. We conclude that most of the astrocytes serve as a buffer system of excess extracellular glutamate and potassium; however, a distinct cell population (NG2-positive, A-type potassium currents) may play an important role for network plasticity."],["dc.identifier.doi","10.1523/JNEUROSCI.4022-03.2004"],["dc.identifier.isi","000188896100012"],["dc.identifier.pmid","14960607"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/48825"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Soc Neuroscience"],["dc.relation.issn","0270-6474"],["dc.title","Diversity of functional astroglial properties in the respiratory network"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
