This study aims to evaluate dental caries and oral hygiene status in children aged 7-12 years with specific learning disabilities (SLD) and to compare the findings with healthy children. Clinical oral examinations, including dmft/DMFT, ICDAS II, Plaque Index, and Gingival Index assessments, will be performed. In addition, questionnaire-based evaluations of oral hygiene habits, dietary habits, and parental supervision during toothbrushing will be conducted.
1,171 studies on the registry are indexed under Dental Caries; 209 are open to participants now.
