ABSTRACT
Aim: A comparative evaluation of the gingival depigmentation by
using a surgical blade and a cryotherapy; 6 months follow-up.
Materials and Methods: 20 systemically healthy patients who were
aged 21-28 years were selected for the study and were treated with
different gingival depigmentation techniques. Cryotherapy and surgical
blade was used for the depigmentation in either of the arches. Pain
levels were assessed using a visual analog scale (VAS) during the
surgery, 1 day, 3 days and 1 week postoperatively. The recurrence of pigmentation was
assessed with melanin pigmentation index (MPI). Results: The gingiva appeared pink and
healthy after both the procedures and there was no recurrence of pigmentation. The clinical
results obtained with the Cryotherapy were esthetically pleasing with great patient comfort
and satisfaction compared to the surgical blade. There was a statistically significant
difference between the levels of pain during the procedure and 3 rd postoperative day between
the two groups. Conversely there was no difference in the levels of pain 24 hours
postoperatively and 1 week postoperatively among the two groups. Conclusion: The
Cryotherapy approach resulted in not as much of bleeding and pain as with scalpel technique.
Although no difference in effectiveness and esthetic outcome were found between the two
approaches, further well-conducted randomized trials would assist to make the absolute
conclusion.
