The invention provides a kind of detection method of bleaching effect；Isolated Tooth is replaced to determine value of chromatism using color difference meter as detection bleaching material to demarcate the whitening effect of product medicament by the use of eggshell；Egg shell smooth in appearance, it is easy to detect；Color and luster stable homogeneous, it is xanthodont also close to human body color fastness；Therefore Isolated Tooth can be replaced to be used as detection bleaching material with egg shell, determines value of chromatism using color difference meter to demarcate the whitening effect of product medicament, there is the superiority that Isolated Tooth does not have.
Description
Technical field
The invention belongs to tooth whitening field, and in particular to a kind of detection method of bleaching effect.
Background technology
With the horizontal raising of domestic, increasing people starts to pay attention to personal appearance.In general, white tooth ratio
Xanthodont dental transition is welcome, therefore tooth whitening is also paid close attention to by more people.Although in the market tooth whitening products beautiful jade is expired
Mesh, but be mostly external import.
The research and development of current domestic tooth whitening products are in the starting stage, and professional standard (YY-T 0825-2011 teeth
The outer bleach product of science tooth) on " detection method of whitening effect ", using the Isolated Tooth of animal as bleaching material.
Rower shortcoming：
1st, from vitro people's incisor or ox incisor as bleaching material is examined, examine needs 6~10 teeth every time, for enterprise
For industry, it is not easy to obtain so much tooth.
2nd, every tooth is derived from different individuals, and because the origin cause of formation of in vitro tooth discoloration is various, bleaching effect has very big
Uncertainty, have a larger difference, detection stability is poor.For a standard, stability is critically important.
3rd, bleaching effect is typically detected using electronics color difference meter, or is estimated using color board.Instrument detects, teeth in vitro table
It is face out-of-flatness, in irregular shape, can have an impact to testing result；Range estimation is very big by subjective impact, and different people naked eyes are to color
Susceptibility is different, and everyone judgement has that its people is poor, not accurate enough.
Thus due to these randomnesss and complexity, for exfactory inspection, the versatility and standard of the standard, all by
Influence.So as to constrain the development of relevant enterprise and industry.
Same sample, 10 Isolated Tooths are detected 10 times respectively with electronics color difference meter, as a result such as following table
Abroad, there is a kind of " detection of blood purine dye paper " method.This method is blood purine coloured plastics card, through dry
After the processing such as hot-tempered, the detection material for bleaching effect experiment is obtained；Its advantage is that surfacing easily detects, even dyeing,
Obtained bleaching effect uniformity is good.Shortcoming is to make complicated, and is easy to fade, and actual discored tooth color fastness
Differ greatly.Due to being easy to bleach, dental bleaching agent especially stronger to bleaching effect, it is difficult to distinguish bleaching effect
The test result of fine or not and final whitening effect
Our company is by theoretical research and passes through substantial amounts of Experimental Comparison, has invented a kind of detection side of tooth whitening effect
Method.
The content of the invention
Find out that human teeth by being divided into enamel (enamel), dentine (ivory), tooth inward outside according to existing research
Marrow (neural gland) etc..Its enamel main component is inorganic matter --- hydroxyapatite, molecular formula：Ca10(OH)2(PO4)6；Brown
The main component of egg shell is calcium carbonate, molecular formula：CaCO3；Both inorganic calcium salts；And the yellow of eggshell color and tooth
It is even to be formed by depositions such as ferrohemes in blood；Egg shell smooth in appearance, it is easy to detect；Color and luster stable homogeneous, color fastness and also connect
Person of modern times's body is xanthodont；Therefore Isolated Tooth can be replaced to be used as detection bleaching material with egg shell, aberration is determined using color difference meter
Value demarcates the whitening effect of product medicament, has the superiority that Isolated Tooth does not have.
The present invention includes following content：A kind of detection method of bleaching effect, Isolated Tooth is replaced to be used as detection by the use of eggshell
Bleaching material, value of chromatism is determined using color difference meter to demarcate the whitening effect of product medicament.
Preferably, the eggshell in the detection method of described bleaching effect is natural brown egg shell；Egg in the market
It is readily available；Color is that egg carries, and is not to be formed the day after tomorrow, and detection stability is good；Egg surface is smooth, is easy to color difference meter
Detection.
Preferably, the detection method of described bleaching effect, comprises the following steps：
Step 1: choosing a diameter of 1cm border circular areas on brown egg shell, its surface color value is detected with color difference meter
As scale value；
Step 2: product medicament to be tested is applied to the egg shell surface circular region, according to product to be calibrated
The method of medicament carries out whitening to the brown egg shell of selection；
Step 3: choosing the whitening Test sites of egg shell with distilled water flushing, filter paper wipes egg shell top layer moisture content simultaneously
Dry；
Step 4: the aberration △ E of scale value and sample are determined with color difference meter.
Preferably, the detection method of described bleaching effect, it is characterised in that：Described color difference meter is to brown egg shell
Detected four times when color value is tested, take the average value of the testing result of four times.
5th, according to the detection method of any described bleaching effect of claim 2~4, it is characterised in that：Described product
Medicament is the medicament for needing to trigger catalytic reaction to carry out whitening by illumination, and such medicament is during tooth whitening without acutely
Physical friction；Comprise the following steps：
Step 1: choosing a diameter of 1cm border circular areas on brown eggshell, detect its surface color value with color difference meter and make
For scale value；
Step 2: the bleaching medicament of test is applied to the eggshell surface border circular areas, smearing thickness about 1mm；
Step 3: spreader portion position about at 1cm, is made light vertical irradiation smear position, beaten under the whitening instrument of selection
Open cold light tooth whitening instrument, irradiation time 20min；
Step 4: after irradiation, with distilled water flushing Test sites, eggshell top layer moisture content and placement 5 are wiped with filter paper
Minute dry, after the aberration △ E of scale value and sample are determined with color difference meter.
