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).
Presence of at least 20 natural teeth
Visible plaque index > 20% at initial assessment
Age between 18 and 65 years
Both sexes eligible
Use of fixed orthodontic appliances
Presence of extensive restorations or fixed dentures on the anterior teeth
Systemic conditions that interfere with the formation of dental biofilm
Use of medications that alter salivary flow
