INDICATOR AND DENTAL INSTRUMENT HAVING INDICATOR
Document Type and Number:
WIPO Patent Application WO/2022/237748
Kind Code:
A1
Abstract:
An indicator (10, 60) and a dental instrument (100) having the indicator (10, 60), the indicator (10, 60) being used for the dental instrument (100). In one embodiment, the indicator (10) comprises a first indicator (20) and a second indicator (30) which are stacked, the first indicator (20) comprising a first pattern layer (21), and the second indicator (30) comprising a second pattern layer (31). An active substance in the oral cavity sequentially permeates through the first indicator (20) and the second indicator (30), and with the permeation of the active substance in the oral cavity, the first pattern layer (21) and the second pattern layer (31) sequentially display patterns. In another embodiment, the indicator (10) comprises an adsorption layer (11) and a display layer (12), and when the adsorption layer (11) adsorbs an active substance in the oral cavity and reaches a saturated state, the active substance permeates through the adsorption layer (11) and into the display layer (12), and the active substance acts on the display layer (12) to display a pattern. In yet another embodiment, the indicator (60) comprises a pattern layer (61) and a scale (70), the pattern layer (61) forming a change region (L) under the action of an active substance in the oral cavity, and the scale (70) being used for indicating position information of the change region (L). The dental instrument (100) having the indicator (10, 60) can optimize the indication effect and improve wearing compliance.
