Use of artificial primary teeth for endodontic laboratory research: experiments related to canal length determination.

Background: Due to the scarcity of exfoliated/extracted human primary teeth with complete roots, artificial teeth were developed as an alternative to be used for educational and laboratory research purposes. This study aimed to assess the feasibility of using artificial primary teeth for conducting laboratory research through an experiment related to canal length determination, comparing artificial teeth with natural teeth.

Methods: Thirty anterior and 21 posterior artificial teeth, and the same number of natural primary teeth were selected.

Homologous prime-boost strategy in neonate mice using Neisseria lactamica.

The aim of the present study was to investigate the immune response to native outer membrane vesicles (NOMVs) of Neisseria lactamica with and without Bordetella pertussis (BP) as adjuvant in intranasal (i.n./i.

Production of monoclonal antibodies against Neisseria meningitidis using popliteal lymph nodes and in vivo/in vitro immunization: prevalence study of new monoclonal antibodies in greater São Paulo, Brazil.

A rapid and efficient method for preparing monoclonal antibody (MAb) serotypes using Neisseria meningitidis outer membrane were used in BALB/c mouse footpads for the immunization. The popliteal lymph nodes were isolated 19 days later for MAb-producing hybridomas, from which the MAbs against the 37 kDa protein were screened. Variations in class 2/3 (PorB) proteins form the basis for meningococcal serotyping.
