Discoloured Teeth Clinical Trial
Official title:
Effect of High Light Intensity Bleaching Protocol Versus Descending Light Intensities Bleaching Protocol on Post Bleaching Teeth Sensitivity: A Randomized Clinical Trial
Compare teeth sensitivity using bleaching protocol with different light intensities (Philips Zoom!™ White Speed whitening gel and lamp, Discus Dental, Inc., Culver City, CA, USA.) versus bleaching protocol with the same light intensity (Philips Zoom!™ Advanced Power whitening gel and lamp, Discus Dental, Inc., Culver City, CA, USA.).
This study will be applied to patients suffering from teeth discolorations. Nowadays, vital
tooth bleaching is one of the most requested cosmetic dental procedures asked by patients who
want and aesthetically more pleasing smile. The American Dental Association (ADA) has advised
patients to ask the dentists to adamant the most suitable bleaching treatment, especially for
those complaining of tooth sensitivity, dental restorations, extremely dark discolorations,
and single dark teeth.
Tooth sensitivity (TS) is the most common clinical side effect of tooth bleaching. Tooth
sensitivity (TS) caused by bleaching procedures usually results in mild and transient pain;
however, it can occasionally cause significant discomfort that is a main deterrent to
patients successfully completing bleaching treatments. Considering that TS has been reported
as a common side effect, affecting more than 60% of the patients that undergo this cosmetic
treatment. Greater tooth sensitivity has been reported with in-office bleaching with adjunct
light compared with no light. Existing literature reveals that activation of bleaching agents
by heat or light may have an adverse effect on pulpal tissue. It was already reported that
the use of intense lights does elevate bleach temperature, but it results in increased
intrapulpal temperatures, which may further impact patient sensitivity and pulpal
health.Hence, in this study different light intensities bleaching protocol will be used
aiming at overcoming this complication.
