Dental Caries and Oral Hygiene Status in Children With Specific Learning Disabilities

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.

Treatment and study plan

Primary outcomes

  1. Dental Caries Experience (dmft/DMFT)

    Time frame: Single assessment at the time of clinical examination

    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.

  2. Caries Severity (ICDAS II)

    Time frame: Single assessment at the time of clinical examination

    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.

Secondary outcomes

  1. Plaque Index (PI)

    Time frame: Single assessment at the time of clinical examination

    Loe & Silness Plaque Index assessing dental plaque thickness at the gingival margin, scored 0-3.

  2. Gingival Index (GI)

    Time frame: Single assessment at the time of clinical examination

    Loe & Silness Gingival Index assessing quality, severity and localisation of gingival disease, scored 0-3.
