news14 Show Preview IDS Cologne 2015 No side-effects Once nHAp comes into contact with the tooth surface, the nano-com- ponentssealthesensitivestructureef- fectivelyandthewhiteningprocedure can be performed without any side-ef- fects. No hypersensitivity occurs dur- ing or after the tooth whitening. The tooth-whitening cycles are shorter: in- stead of three cycles of 20 minutes each,sixcyclesof10minuteseachare recommended. This is also due to the low hydrogen peroxide concentration and has proven to be very successful. Owing to the more frequent and shorter cycles, freshly activated low- level hydrogen peroxide is applied to the surfaces. Furthermore, PrevDent responded quickly in the develop- ment of post-treatment products and introduced a toothpaste that contains nHAp.StudiesattheUniversityofPisa have already demonstrated the tooth- paste’s desensitising effect. In addi- tion, brushing one’s teeth with the PrevDent nHAp toothpaste alone has a rewhitening effect, as the continu- ously remineralised surface reflects light better. Bio-whitening In addition to the positive effects of the use of nHAp described above, it has to be stated that the tooth-whiten- ing effect of the PrevDent CrWR sys- tem is very good, even though the teeth do not appear to be quite as white directly after treatment. They have the same colour one would nor- mally expect a day after conventional whitening with a higher-concentra- tion gel. This is mainly because the teeth are not as heavily dehydrated. Onedayafterwhitening,however,the colour of the teeth is identical to that of teeth whitened conventionally, but withoutthepainfulside-effects.Inthe truest sense of the word, the proce- durecanbedescribedasabio-whiten- ing. The new technology extends the range of indications of tooth-whiten- ing treatment. Furthermore, patients withhighlydiscolouredteethandfear of the side-effects can be treated ear- lier. Frequent whitening can be per- formed in shorter intervals com- pletely free of side-effects. In my opin- ion, there are no longer any contra-in- dications to whitening treatments owing to the introduction of nHAp. In the future, treatment with nHAp is likely therefore to increase exponen- tially. No more hypersensitivity While further research is neces- sary, it has been determined that whitening with nHAp improves and sealsthetoothstructureandhasmade once-dreadedhypersensitivityathing of the past. It remains to be seen how the market will react in the near fu- ture. Most certainly, more tooth- whiteningproductswillbedeveloped. Many manufacturers will seek to in- troduce similar nHAp-containing products to the market. In any event, this is a result of the new EU directive. Ithasgivennewimpetustothewhiten- ing market.
