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. Digital models will be used to quantify plaque-covered surface measures and to generate 3D maps of plaque-retentive areas.",[25,26,27,28,29],"Dental Plaque Accumulation","Oral Hygiene, Oral Health","Dental Materials","Dental Plaque Imaging Methods","Dental Plaque Index","NOT_YET_RECRUITING","2026-02-19",{"date":33,"type":34},"2026-02-23","ACTUAL",{"date":36,"type":21},"2026-03-16",{"date":38,"type":21},"2027-03-24",{"name":40,"class":41},"Trakya University","OTHER",1,{"id":44,"slug":45,"hasResults":11,"nctId":46,"briefTitle":47,"officialTitle":47,"acronym":4,"eligibilityCriteria":48,"healthyVolunteers":16,"sex":17,"minAge":18,"maxAge":49,"enrollmentInfo":50,"targetDuration":4,"studyType":22,"phases":4,"briefSummary":52,"conditions":53,"keywords":58,"overallStatus":30,"whyStopped":4,"lastUpdateSubmitDate":64,"lastUpdatePostDateStruct":65,"startDateStruct":67,"completionDateStruct":69,"leadSponsor":71,"locationsCount":42},"100604653","digital-quantification-of-dental-plaque-based-on-intraoral-scanner-images-100604653","NCT07152314","Digital Quantification of Dental Plaque Based on Intraoral Scanner Images","Inclusion Criteria:\n\n* Presence of at least 20 natural teeth\n* Visible plaque index \\> 20% at initial assessment\n* Age between 18 and 65 years\n* Both sexes eligible\n\nExclusion Criteria:\n\n* Use of fixed orthodontic appliances\n* Presence of extensive restorations or fixed dentures on the anterior teeth\n* Systemic conditions that interfere with the formation of dental biofilm\n* Use of medications that alter salivary flow","65 Years",{"count":51,"type":21},20,"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.
