| Summary: | Introduction: Replication of natural skin colour in maxillofacial
prosthesis has been traditionally done using trial and error
method, as concrete shade guides are unavailable till date.
Hence a novel custom made intrinsic silicone shade guide has
been attempted for Indian population.
Aim: Reconstruction of maxillofacial defects is challenging, as
achieving an aesthetic result is not always easy. A concoction of
a novel intrinsic silicone shade guide was contemplated for the
study and its reproducibility in clinical practice was analysed.
Materials and Methods: Medical grade room temperature
vulcanising silicone was used for the fabrication of shade tabs.
The shade guide consisted of three main groups I, II and III
which were divided based upon the hues yellow, red and blue
respectively. Five distinct intrinsic pigments were added in
definite proportions to subdivide each group of different values
from lighter to darker shades. A total number of 15 circular
shade tabs comprised the guide. To validate the usage of the
guide, visual assessment of colour matching was done by
four investigators to investigate the consent of perfect colour
correspondence. Data was statistically analysed using kappa
coefficients.
Results: The kappa values were found to be 0.47 to 0.78 for
yellow based group I, 0.13 to 0.65 for red based group II, and
0.07 to 0.36 for blue based group III. This revealed that the
shade tabs of yellow and red based hues matched well and
showed a statistically good colour matching.
Conclusion: This intrinsic silicone shade guide can be effectively utilised for fabrication of maxillofacial prosthesis with
silicone in Indian population. A transparent colour formula
with definite proportioning of intrinsic pigments is provided for
obtaining an aesthetic match to skin tone. |
