Quantitative Analysis of Plaque Removal Efficiency in Children With Specific Learning Disabilities

Dental plaque is one of the major etiological factors associated with oral diseases such as dental caries and gingival inflammation. Effective plaque control through proper toothbrushing habits plays an important role in maintaining oral health in children. However, children with specific learning disabilities (SLD) may experience difficulties in acquiring and maintaining adequate oral hygiene behaviors because of limitations in learning processes, attention, and motor coordination.

The aim of this study is to evaluate the short-term effectiveness of structured toothbrushing education in children aged 7-12 years with SLD and to compare plaque removal performance with healthy children using photograph-based quantitative analysis methods.

The study will be conducted at the Department of Pediatric Dentistry, Faculty of Dentistry, Alanya Alaaddin Keykubat University. Children diagnosed with SLD and age-matched healthy controls will be included in the study. All participants will receive standardized toothbrushing education supported by visual cards and educational videos. Educational materials will be prepared in a child-friendly format and based on the Modified Bass toothbrushing technique.

A plaque-disclosing agent will be applied to all participants to visualize dental plaque before photography. Intraoral photographs will be obtained under standardized conditions using the same lighting, camera settings, and imaging protocol. At each evaluation session, intraoral photographs will be obtained both before and after toothbrushing in order to assess immediate plaque removal effectiveness. Quantitative plaque analysis will be performed using ImageJ/FIJI software by calculating plaque percentage (P%) values from disclosed plaque areas.

Participants will use standardized toothbrushes and toothpaste throughout the study period. During the 2-week follow-up period, children will be encouraged to continue toothbrushing under parental supervision using the taught brushing technique. At follow-up visits, Plaque Index, Gingival Index, plaque disclosure, and intraoral photography procedures will be repeated to evaluate changes in plaque removal effectiveness and oral hygiene performance.
