About this study
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| 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. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Dental Caries Experience (dmft/DMFT)
Decayed, missing, and filled teeth index for primary (dmft) and permanent (DMFT) dentition, assessed according to WHO criteria using mirror and periodontal probe under dental unit light.
Measured: Single assessment at the time of clinical examination
Caries Severity (ICDAS II)
International Caries Detection and Assessment System II score recorded for each tooth using visual and tactile examination. The highest ICDAS II code recorded for each patient is used as the individual score.
Measured: Single assessment at the time of clinical examination
Secondary outcomes (2)
Plaque Index (PI)
Loe \& Silness Plaque Index assessing dental plaque thickness at the gingival margin, scored 0-3.
Measured: Single assessment at the time of clinical examination
Gingival Index (GI)
Loe \& Silness Gingival Index assessing quality, severity and localisation of gingival disease, scored 0-3.
Measured: Single assessment at the time of clinical examination
