Previdente is pleased to inform you that a revolutionary technique has been introduced that helps anxious/fearful patients remain calm enough for the visit to take place properly.

The responsible for implementing the technique is Dr. Sérgio Pereira, Previdente’s clinical director, who in 2004 acquired the necessary qualifications to apply this method – Qualification Course in Inhalational Sedation with Nitrous Oxide.

We would also like to inform you that Previdente is currently undergoing a Quality certification process (ISO 9001) in view of constantly improving our services and fully responding to our patients’ needs.
