Abstract

A tooth bank is a nonprofit institution that must be linked to a dental school; it is responsible to meet the academic and scientific needs with certified purposes by the institutional ethics committee. The duty of the tooth bank is to provide users teeth completely disinfected to prevent and reduce risks caused by microorganisms that survive in them. This observational experimental study evaluated the disinfection protocols of teeth from the tooth bank of the Faculty of Dentistry of Universidad Santo Tomas of Bucaramanga, for that purpose, the collection of 39 teeth was attained and donated to the dental clinics of USTA, afterwards the execution of washing and disinfection protocols of the teeth was performed with glutaraldehyde and sodium hypochlorite. The determination of effectiveness of the protocols was done through the turbidity test as an indicator of microbial growth. The results demonstrated that sodium hipoclorite at 5.25% did now allow any microbial growth, In the case of glutarldehyde, as well as the sodium hiplocrite did not allow microorganism growth but in the other hand it was observed that it altered the evaluated dental structures generating softness and dislodgement of its components. As a conclusion in this investigation is it established that the sodium hiploclorite at 5.25% during 7 days in direct contact is effective in the disinfection of the dental pieces, being the protocol of choice due to the advantages and benefits of this agent.
