Discoloration, Tooth Clinical Trial
Official title:
Shade Evaluation for Clinical Color Change of Discolored Teeth Treated by Bleaching vs Laminate Veneers.
The present study is aimed to evaluation of shade for clinical color change of discolored teeth treated by bleaching vs laminate veneers.
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.
