Prevalence of microorganisms in root canals of human deciduous teeth with necrotic pulp and chronic periapical lesions Prevalência de microrganismos em canais radiculares de dentes decíduos de humanos com necrose pulpar e lesão periapical crônica
The objective of this study was to evaluate bacterial prevalence in 31 root canals of human deciduous teeth with necrotic pulp and periapical lesions using bacterial culture. After crown access, the material was collected using absorbent paper points for microbiological evaluation and determination of colony forming units (CFU). Anaerobic microorganisms were found in 96.7% of the samples, black...
متن کاملEffect of different dye solutions on the evaluation of the sealing ability of mineral trioxide aggregate Efeito de diferentes soluções corantes na avaliação da capacidade seladora do agregado de trióxido mineral
Alkaline materials have shown incompatibility with methylene blue dye in leakage experiments. The goal of the present study was to analyze the effect of different dyes on the evaluation of the apical sealing ability of Mineral Trioxide Aggregate root-end fillings. Fifty-six extracted human canines were submitted to root canal instrumentation and obturation. After apical resection, retrograde ca...

he purpose of this research was to evaluate the diffusion of calcium (Ca+2) and hydroxyl (OH-) ions from materials with a calcium hydroxide base Ca(OH)2 through the intact roots of deciduous teeth. This diffusion of ions is important for periapical healing. Forty-six deciduous teeth were selected and instrumented to their working length with #40 files. The teeth were washed during cleaning and ...
متن کاملInfluence of the spatulation of two zinc oxide-eugenol-based sealers on the obturation of lateral canals Influência da espatulação de dois cimentos à base de óxido de zinco e eugenol na obturação de canais laterais
The objective of this research was to evaluate, in vitro, the importance of the correct manipulation of endodontic sealers, correlating it with flow rate and with the consequent obturation of root canals. Twenty-four human canines were prepared, 1 mm from the apex, with K-files up to size 50, by means of the step-back technique. Six lateral canals were then drilled in each tooth, with size 10 f...
