Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Hypothesis 1a): overall tooth-contact time, occlusal, outer surfaces via video analysis and software Interact, 2nd measurement time point Hypothesis 1b): overall oral cleanliness after oral hygiene as assesed via marginal plaque index (MPI), 2nd measurement time point Hypothesis 1c): self-assessed overall oral cleanliness after oral hygiene as computed via self-assessed cleanliness in segments (own questionnaire), 2nd measurement time point Hypothesis 2): N/A (Repeated measures correlation 1. vs. 2. measurement time point reagrding all behavioral parameters named in 1) Hypothesis 3): overal oral cleanliness self-assessed vs. measured via MPI, 2nd measurement time point Hypothesis 4): papillary bleeding index, 1st measurement time point; self efficacy expectations, 2nd measurement time point | — |
Secondary
| Measure | Time frame |
|---|---|
| Hypothesis 1a): tooth contact time oral, within segments, with circling movements, with horizontal movements; QIT-S; number of segments brushed sufficiently long; number of segments neglected; via video analysis and software Interact, 2nd measurement time point Hypothesis 1b): oral cleanliness after oral hygiene as assessed by Quigley Hein Index modifizied by Turesky; papillary bleeding index; 2nd measurement time point Hypothese 1c): self-assessed oral cleanliness in segments (own questionnaire) 2nd measurement time point Hypothesis 2): N/A (Repeated measures correlation 1. vs. 2. measurement time point reagrding all behavioral parameters named in 1) Hypothesis 3): MPI vs. self assessed oral cleanliness - resepective measures in segments; second measurement time point Hypothesis 4): mean attachment loss, maximum attachment loss, mean probing depth, maximum probing depth: 1st measurement time point; self efficacy expectations: 2nd measurement time points. | — |
