Summary

This diagnostic validation study aims to develop and validate a digital method for dental biofilm quantification using three-dimensional images obtained by an intraoral scanner. Twenty participants will undergo intraoral scanning at three time points: before and after plaque disclosure, and after supervised toothbrushing. The digital method's accuracy will be compared with traditional clinical assessment methods (Turesky Plaque Index).
