toothbrush

Tooth-brushing purpose

Record the stated primary use and the evidence supporting classification as a toothbrush.

1. What establishes that this implement is intended to brush tooth surfaces? definition
2. Does its primary function instead place it with interdental brushes, tongue cleaners or non-oral cleaning brushes? boundary

Complete brushing assembly

Record whether the object is a complete toothbrush and which parts are integral or detachable.

1. Which parts constitute this toothbrush in its present configuration? definition
2. Is the observed object a complete implement, a detached head or a handle awaiting a required head? boundary

Contact surface profile

Record contact-element material, layout and stated stiffness without inferring unverified performance.

1. What contact elements are present, and how are they arranged across the working surface? definition
2. What source supports any material, stiffness or tip-finish designation? provenance

Head clearance and reach

Record dimensions and access constraints while keeping individual suitability unresolved unless assessed.

1. What are the head dimensions and the neck length and angle? measurement
2. What evidence establishes whether this geometry can reach the intended brushing surfaces for the intended user? boundary

Controlled brushing motion

Record the actuation mechanism and grip features relevant to controlling the head.

1. Is brushing motion supplied by the user's hand, a powered mechanism or a documented combination? definition
2. Can the intended user securely hold and operate this handle under the expected brushing conditions? action

Powered operation readiness

Record power availability, functional controls and observed feedback without assuming that all powered brushes share features.

1. Which power source, operating modes and feedback features are documented for this toothbrush? provenance
2. Do observed charge indications, head movement or fault signals permit the intended operation under its instructions? action

Personal head identification

Record identifying marks and assignment uncertainty, including configurations with individually assigned detachable heads.

1. Who is assigned this toothbrush or fitted head, and how is that assignment evidenced? provenance
2. If assignment or prior use is uncertain, what verified guidance determines the next action? action

Care state and next step

Record care-relevant observations without equating visible cleanliness with microbiological safety.

1. What residue, retained moisture or contact with other stored brush heads is observed? measurement
2. Which documented cleaning, drying and storage actions apply to this head and handle? action

Condition-based review

Record observed deterioration and the evidence used to judge whether it requires intervention.

1. What splaying, deformation, missing elements, cracks or attachment looseness are present? measurement
2. Which verified condition or service-life criteria require head replacement or withdrawal of the whole toothbrush? action

Supported renewal path

Record replaceable parts and compatibility evidence before selecting a renewal action.

1. Which heads or power components are documented as compatible and user-replaceable for this toothbrush? provenance
2. Can the identified issue be resolved through a supported component action, or must the toothbrush be retired? action
