Objectives:
Matching the shade of
a porcelain-fused-to-metal restoration to that of
the natural teeth is an important goal of the
restorative dentist. We aimed to compare patients’,
student's and prosthodontist’s satisfaction with the
achieved shade of porcelain-fused-to-metal
restorations.
Methods:
One or more porcelain-fused-to-metal crowns in the
anterior zone were completed in 23 patients who
needed prosthetic rehabilitation. After treatment’s
completion, a validated questionnaire to assess
satisfaction with the shade match was used in all
patients, one student and the prosthodontist who
supervised these procedures. The Kendall’s tau-b
statistic and the Weighted κ Statistic were used to
analyze the level of agreement between the ratings
given by patients, the prosthodontist and the
student.
Results:
Patients rated 86.95% of the crowns’ shade as good,
and 13.04% were rated as satisfactory. The
prosthodontist rated 30.55% crowns’ shade as good,
52.77% as satisfactory and 16.67 % as poor, and the
student rated 69.44% and 30.55% of the crowns’ shade
as good and satisfactory respectively. The level of
agreement between student and prosthodontist, as
computed by the weighted κ, was 0.25, and the level
of agreement between patients and prosthodontist was
0.09.
Conclusions:
With this simple tool, we demonstrated that although
the majority of patients were highly satisfied with
the shade-match of the restoration, the level of
agreement between patients and prosthodontist was
low. However the patient satisfaction is the most
important goal of the aesthetic restorations and
this was achieved in this cohort.
