Outcome Measures

Primary Outcomes (1)

  • Change in Standardized Mini Mental Test (SMMT) score at 6 months

    The baseline SMMT score was recorded. After 6 months, the 6th month SMMT score was recorded. Change in SMMT score at 6 months= Baseline SMMT score-6th SMMT score.

    Baseline and 6th month

Diagnostic Test: Baseline Standardized Mini Mental TestDiagnostic Test: 6th month Standardized Mini Mental Test

Stage II

Stage II Alzheimer's Group (n=29): Individuals diagnosed with probable Alzheimer's disease with moderate (moderate stage) dementia according to the Clinical Dementia Rating Scale.

Diagnostic Test: Baseline Standardized Mini Mental TestDiagnostic Test: 6th month Standardized Mini Mental Test

Stage III

Stage III Alzheimer's Group (n=19): Individuals diagnosed with probable Alzheimer's disease with severe (advanced stage) dementia according to the Clinical Dementia Rating Scale.

Diagnostic Test: Baseline Standardized Mini Mental TestDiagnostic Test: 6th month Standardized Mini Mental Test

Interventions

Cognitive status assessment was done with Standardized Mini Mental Test.

Stage IStage IIStage III

Cognitive status assessment was done with Standardized Mini Mental Test.

Also known as: Periodontal Examination: Toothed/edentulous condition, occlusal relationship type and periodontal status were evaluated by periodontal examination.
