Comparison of rotary and manual instrumentation techniques on cleaning capacity and instrumentation time in deciduous molars.
Although no differences were found for cleaning capacity, the reduction of instrumentation time by the rotary technique was a relevant clinical factor for endodontic treatment.
Effect of calcium hydroxide on bacterial endotoxin in vivo.
It can be concluded that the bacterial endotoxin caused a periapical lesion and that calcium hydroxide detoxified the lipopolysaccharides in vivo.
Ex vivo evaluation of the accuracy of two electronic apex locators during root canal length determination in primary teeth.
Root ZX II and Mini Apex Locator proved useful and accurate for apex foramen location during root canal length measurement in primary incisor and molar teeth with different stages of physiological root resorption.
Importance of bacterial endotoxin (LPS) in endodontics.
The literature concerning the biological activity of endotoxin and the relevance of its inactivation during treatment of teeth with pulp necrosis and chronic periapical lesion was reviewed.
Prevalence of microorganisms in root canals of human deciduous teeth with necrotic pulp and chronic periapical lesions.
In human deciduous teeth root canals with necrotic pulp and periapical lesions the infection is polymicrobial, with a large number of microorganisms and a predominance of streptococci and anaerobic microorganisms.
