Dental Caries and Oral Hygiene Status in Children With Specific Learning Disabilities (SLD-OH)

May 21, 2026 updated by: Gül Keskin, Alanya Alaaddin Keykubat University
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.

Cohorts and Interventions

Group / Cohort
Children with Specific Learning Disorder (SLD)
Children aged 7-12 years diagnosed with specific learning disorder by a psychiatrist, presenting to Alanya Alaaddin Keykubat University Faculty of Dentistry. Dental caries experience (dmft/DMFT), caries severity (ICDAS II), plaque index and gingival index will be assessed.
Healthy Control Children
Children aged 7-12 years with no psychiatric diagnosis, confirmed healthy by a psychiatrist, presenting to Alanya Alaaddin Keykubat University Faculty of Dentistry Paediatric Dentistry Clinic. Dental caries experience (dmft/DMFT), caries severity (ICDAS II), plaque index and gingival index will be assessed.
