Toothbrush in the Genesis and Prevention of Dental Recessions

Study Overview
=================
Brief Summary
-----------------
The aim of this research is to evaluate the effect of brushing on gingival recessions and to understand the impact of manual brushing and brushing with mechanical aid on their evolution. The study involves the recruitment of 90 patients with or without gingival recessions at the Dentistry service of the University of Genoa. The first phase involves the evaluation of the brushing force on the genesis of gingival recessions. A questionnaire will be filled out and the same toothbrushes and toothpastes will be provided for one month to 30 patients with recessions and 30 patients without recessions. After a month, the wear of the manual toothbrush and the gingival health indices will be measured. In this phase 60 patients with recessions will be divided into two groups according to the oral hygiene method that will be recommended. In the first group a super soft toothbrush will be delivered, in the second group a mechanical toothbrush. Gingival health indices will be taken and an intraoral scan will be done to measure recessions. At 6 months and 12 months the indices will be measured again and compared between the two groups. This research has two objectives: Evaluate the differences in wear of the manual toothbrush head after one month of use between patients with gum recession and patients without gum recession. In the case of greater wear among patients with recessions it could be assumed that a greater brushing force is able to determine the formation of recessions. Try to understand if there are differences between the super soft manual toothbrush and the mechanical toothbrush regarding the effectiveness of use and the delicacy on recession. Both tools are currently recommended for patients with recessions, but there are no studies in the literature comparing the two tools.
