• Conditions: Discoloration, Tooth
• Interventions: Procedure: Bleaching agent ( BOOST 40%); Procedure: laminate veneers(lithium-silicate)

• Registration Number: NCT03621163
• Lead Sponsor: Cairo University

Brief Summary

The present study is aimed to evaluation of shade for clinical color change of discolored teeth treated by bleaching vs laminate veneers.

Detailed Description

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.
