Detaljeret beskrivelse

Dental aesthetics, including tooth color, is of great importance for majority of the people and any discoloration or staining can affect their quality of life negatively1,2. In the UK it has been reported that 28% of grownups are dissatisfied with the appearance of their teeth and in the USA that 34% of grownups population are dissatisfied with their current tooth color. Moreover, in a survey of 3215 subjects from the UK 50% have admitted that they had some kind of tooth discoloration3,4.

Tooth bleaching has become one of the most popular aesthetic dental treatments. Because tooth bleaching is an effective, non-invasive procedure for the change of tooth discoloration, it is the best of treatment options for improving teeth color 5.

Ceramic restorations with excellent biocompatibility are widely used to achieve highly aesthetic characteristics in fixed prosthodontics6. Porcelain laminate veneers have become a popular method of treated tooth discoloration. But are expensive, brittle and difficult to repair7.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: bleaching agent
intervention : bleaching agent ( Boost 40%)
Procedure: Bleaching agent ( BOOST 40%)
Opalescence Boost 40% is a 40% hydrogen peroxide, medical power bleaching gel. The jet mix syringe ensures freshness for each application and precise dosing of the activator. One barrel contains a unique chemical activation with sodium fluoride and potassium nitrate, which have been demonstrated to reduce caries susceptibility, lower sensitivity, and improve enamel micro-hardness. The other barrel contains the concentrated hydrogen peroxide. When mixed, Opalescence Boost results in a 1.1% fluoride and 3% potassium nitrate concentration.
Aktiv komparator: laminate veneers
laminate veneers ( monolithic lithium - silicate)
Procedure: laminate veneers(lithium-silicate)
A lithium-silicate glass ceramic is newly introduced to the market. After crystallization, it demonstrates an ideal combination of strength, aesthetics and translucency that mirrors the vitality of natural teeth for fabrication of full anatomic anterior and posterior crowns. It differentiated from other ceramics by its high chipping resistance, due to their monolithic composition and average flexural strength of 385 MPa. Also Milling Block has good wear resistance due to the high content of ultra-fine nano-meter size crystalline structure. Lithium-silicates ceramic blocks are available in the commonly used VITA Classical and Chromascop Bleach shades.
