Streszczenie

Wprowadzenie. Wybielanie zębów stało się zabiegiem standardowo wykonywanym przez większość lekarzy dentystów zajmujących się stomatologią estetyczną. W dostępnym piśmiennictwie jest niewiele doniesień poświęconych ocenie trwałości uzyskanego efektu leczniczego w postaci zmiany koloru uzębienia.
Cel pracy. Ocena trwałości efektu działania preparatu do profesjonalnego wybielania zębów.
Materiał i metody. Zabiegowi wybielania zębów w warunkach gabinetu stomatologicznego poddano 18 ogólnie zdrowych pacjentów w wieku 22–32 lat. Zabieg przeprowadzono z użyciem preparatu Opalescence Xtra Boost® (Ultradent USA). Przed zabiegiem wybielania oraz 7 dni po jego przeprowadzeniu wykonano analizę kolorymetryczną siekaczy i kłów szczęki za pomocą spektrofotometru dentystycznego Spectroshade (MHT, Włochy). Pomiary kolorymetryczne wykonano ponownie po 6 miesiącach i po roku od zakończenia zabiegu wybielania.
Wyniki. Bezpośrednio po zastosowaniu preparatu Opalescence Xtra Boost obserwowano istotną średnią zmianę koloru ΔE na poziomie 3,89 punktu. Po roku od zakończenia zabiegu średnia zmiana koloru w porównaniu ze stanem wyjściowym wynosiła 3,50 (p = 0,05) punktu dla zębów wybielanych preparatem firmy Ultradent.
Wnioski. Preparat Opalescence Xtra do profesjonalnego wybielania zębów długotrwale zmienia kolorystykę tkanek twardych, tj. szkliwa i zębiny w warunkach in vivo.

Abstract

Background. Teeth bleaching became a standard medical procedure performed in dental practices focused on aesthetic dentistry. There are not many reviews concerning the assessment of long-term effect of bleaching materials in the context of teeth color change.
Objectives. The aim of the study was to assess the effect durability of professional tooth bleaching agent. Materials and Methods. 18 generally healthy patients aged 22-32 were subjected to in-office teeth bleaching. The patients were treated with Opalescence Xtra Boost® (Ultradent, USA) bleaching gel. Before bleaching and 7 days after bleaching a colorimetric analysis of incisors and canines of the maxilla was performed using a dental spectrophotometer Spectroshade (MHT). Colorimetric measurements were repeated after 6 months and again after one year from completion of bleaching.
Results. After application of Opalescence Xtra Boost agent, a mean color change ΔE of 3.89 points was observed. (p = 0.05) One year after treatment, a mean color change compared to the initial condition was 3.50 points (p = 0.05) for teeth bleached Ultradent’s agent.
Conclusion. Professional teeth bleaching agent examined at present study has long-term effect on hard tissue color change, i.e. enamel and dentine in in vivo conditions.
