Efficacy of Periodontal Risk Communication in Patients With and Without History of Tooth Loss

"Test treatment will consist of a single session structured as follows: (i) information on periodontal diagnosis (as formulated according to the classification system of the 2017 World Workshop for the Classification of Periodontal Diseases and Conditions); (ii) information on periodontal risk level (as calculated with the PerioRisk tool proposed by Trombelli et al. 2009) and profile (i.e., the magnitude of the contribution of each PerioRisk parameter to generate the patient risk level); (iii) information on treatment plan and oral hygiene instructions, with emphasis to treatment goals based on the PerioRisk output.~The operators will be trained to administer test treatment in approximately 8 minutes, but the duration of the session will be extended for additional questions and answers upon patient request."

"Control treatment will consist in a single session structured as follows: (i) information on periodontal diagnosis (as formulated according to the classification system of the 2017 World Workshop for the Classification of Periodontal Diseases and Conditions); (ii) information on treatment plan and oral hygiene instructions, and treatment goals. Although the general concept of risk of periodontitis incidence/progression will be explained, no mention will be made to the patient risk level as calculated with PerioRisk or any other tool.~The operators will be trained to administer control treatment in approximately 8 minutes, but the duration of the session will be extended for additional questions and answers upon patient request."
