A statistical analysis of anaerobic versus aerobic culturing in endodontic therapy

Irradiation of infected root canals with a diode laser in vivo: Results of microbiological examinations

“…In 1990, Ando and Hoshino examined the presence of anaerobic vs aerobic microorganisms in the root canal dentine; they stated, like Zielke et al in 1976, that anaerobic microorganisms are predominant especially in deep layers of infected root dentine [29,30]. Our study confined itself on aerobic culturing; however, these aerobic microorganisms were used as an indicator for the antimicrobial effects of diode laser irradiation.…”

Complications during root canal irrigation

“…It has been demonstrated to be an effective agent against a broad spectrum of bacteria and to dissolve vital as well as necrotic tissue (6). The benefits of the good tissuedissolving and disinfecting capabilities of sodium hypochlorite, due to the release of chloramine, have been demonstrated in several investigations (6)(7)(8)(9)(10)(11)(12)(13)(14). The concentration of the irrigant is still a matter of debate and remains controversial; many authors recommend a 5.25% concentration of sodium hypochlorite (3) while others prefer a lower concentration of 3% or even 0.5% (15,16).…”

A protocol for polymerase chain reaction detection of Enterococcus faecalis and Enterococcus faecium from the root canal

“…1964, Engström 1964, Möller 1966, Mikkelsen & Theilade 1969, Morse 1970, Zielke et al . Hence, the efficacy of various combat regimes is often assessed by sampling the root canal for the presence of persisting microbes.…”

“…However, the accuracy of this methodology has been questioned and the risks of obtaining false positive and false negative recordings have been pointed out (Bender et al . 1964, Engström 1964, Möller 1966, Mikkelsen & Theilade 1969, Morse 1970, Zielke et al . 1976, Safavi et al .…”
