The main questions it aims to answer are:\n\n* How well does the plaque-covered surface measurement derived from 3D intraoral scanner data agree with TMQHPI scores after plaque disclosure?\n* How sensitively do the two methods detect changes in plaque levels after supervised toothbrushing?\n* Do plaque accumulation patterns differ between natural tooth surfaces and restorative materials (direct composite restorations and indirect ceramic veneers), and where are plaque-retentive areas most frequently located?\n\nParticipants (≥18 years) will receive routine professional mechanical plaque removal as part of standard clinical care. They will then be asked to avoid mechanical and\u002For chemical plaque control for 4 days. At the follow-up visit, participants will undergo:\n\n1. An intraoral scan and standardized photographs of the full dental arch,\n2. Plaque disclosure followed by repeat scanning\u002Fphotography and TMQHPI scoring by a periodontist,\n3. Supervised toothbrushing using the modified Bass technique for 2 minutes, followed by a final scan and photographs.
