Abstract

The home bleaching procedure is a tooth whitening process that can be done at home using a prostheticlike
device
called
a
tray
or
nightguard
with
16%
carbamide
peroxide
concentration.
Chemicals
such

as
carbamide
peroxide
can
have
a
sensitive
effect
on
the
teeth.
Green
pear
(Pyrus
communis)
is
believed

to
have
a
content
that
can
remove
stains
on
the
surface
of
the
teeth
and
whiten
teeth
such
as
malic
acid,

citric

acid, oksalat acid, sicamat acid, fumarate acid, tartaric acid and lactic acid. This study was a
laboratory experimental study of the effectiveness of tooth discoloration applied with green pears
(Pyrus communis) and then compared with the color of teeth applied to 16% carbamide peroxide. Tooth
color changes that occurs is measured using the shade guide. In the group of green pear juice (Pyrus
communis) it produces the final color A3.5 and A3, while in the carbamide peroxide group 16%
produces the final color A1. The results of the study were analyzed using Wilcoxon and Mann Whitney
analysis to see the comparison of the effectiveness of tooth color change in the teeth. Based on the
results of the study it can be concluded that the application of green pear (Pyrus communis) is less
effective than the application of 16% carbamide peroxide.
