Ocorrência de Mannheimia haemolytica e de Pasteurella multocida em ovinos sadios e com enfermidade respiratória

Frequency of Mannheimia haemolytica and Pasteurella multocida in the respiratory tract of lambs in the region of Botucatu, SP, Brazil, was studied. Nasopharingeal and oropharingeal swabs were obtained from 262 animals: 180 from healthy and 82 from animals with respiratory diseases. M. haemolytica was the most prevalent (47%), followed by the association of M. haemolytica and P. multocida (27%), and P. multocida (11%). Animals with respiratory disease presented higher occurrence of P. multocida in the nasopharynx as compared to healthy animals (P<0.05). No significant difference in isolation rate of M. haemolytica, P. multocida, and association of these microorganisms in the oropharynx of healthy and affected animals was observed.

Sealability of MTA and calcium hydroxide-containing sealers

Objectives: The aim of this study was to evaluate the apical sealability of Fillapex (R), Endo-CPM-Sealer (R) and Sealapex (R). Material and Methods: Ninety-four freshly extracted single-rooted teeth were selected and decoronated. All teeth were radiographed to confirm the existence of a single and straight root canal, which was prepared using Protaper Universal and 2.5% sodium hypochlorite. The teeth were randomly divided in groups of 10 specimens each according to the sealer, and the canals were filled using the single cone technique and one of the sealers. Four additional teeth were used as controls. The teeth were submitted to dye leakage with Rhodamine B for 24 h but using vacuum on the initial 15 min. Thereafter, they were cut longitudinally and the leakage was measured in a linear fashion from apex to crown. Data were analyzed by ANOVA and Tukey's tests at 5% significance level. Results: Fillapex (R) and Sealapex (R) showed significantly less dye leakage than Endo-CPM-Sealer (R) (p<0.05). Conclusions: It was concluded that Fillapex (R) and Sealapex (R) were able to prevent apical dye leakage differently from Endo-CPM-Sealer (R).
