Oral State Evaluation Using Non-Practice Period Risk Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral health evaluation techniques do not account for the changing risks associated with the length of an oral care non-practice period, leading to inadequate assessment of oral health states, particularly when tartar formation begins.
Innovation Solution
An evaluation device and system that identify the length of an oral care non-practice period and evaluate oral health based on this duration, incorporating a non-practice period identifying section and an evaluation section to quantify risks and provide feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional brushing evaluation techniques are used, then brushing quality can be assessed, but the changing risks associated with non-practice period length are not considered
Solution Approach 1:
The system performs preliminary identification of the non-practice period length before conducting the oral state evaluation. By determining how long it has been since the subject last engaged in oral care activities, the system prepares the necessary contextual information in advance to adjust the evaluation criteria and provide more accurate risk assessment.
Solution Approach 2:
The evaluation criteria are made dynamic by adjusting them based on the identified non-practice period length. As the non-practice period extends, the evaluation system adapts the risk thresholds and evaluation standards to reflect the changing oral health risks, making the assessment more responsive to the subject's actual oral care status.
2Device complexity
If tartar formation is not considered in evaluation, then simple brushing metrics can be used, but the actual oral health risk is underestimated
Solution Approach 1:
The evaluation system adds a new dimension to the assessment by incorporating time-based factors (non-practice period length) into the traditional brushing metrics. This transforms the evaluation from a static snapshot of brushing quality to a dynamic assessment that considers both brushing performance and the temporal context of oral care abandonment, enabling detection of tartar formation risks.

AI summary
Provided is an evaluation device and others which are capable of properly evaluating an oral state. An evaluation device (1) includes: an non-practice period identifying section (103) for identifying the length of a non-practice period, which is a period during which a subject of oral state evaluation does not practice predetermined oral care; and an evaluation section (105) for evaluating the oral state of the subject depending on the length of the non-practice period.
