Brief Summary

The present study aims at validating the Italian version of one of the most widely used epidemiological questionnaires for periodontitis screening: the CDC/AAP questionnaire \[hereafter referred to as the CDC/AAP\_ITA questionnaire\]. The study also aims to develop a modified version of the CDC/AAP questionnaire, enriched with additional questions, and to evaluate its diagnostic accuracy \[hereafter referred to as the QSIdP questionnaire\]. The study will be conducted at the Unità Complessa di Odontoiatria, Azienda Unità Sanitaria Locale (A.U.S.L.) of Ferrara (Director: Prof. Leonardo Trombelli), in collaboration with nine (9) other Italian clinical centers.
