Comparison of the effects of Persica and protact mouthwash on gingival healing after crown lengthening surgery ‑ A double‑blinded randomized clinical trial

Abstract

Background: Plaque control is one of the main issues after crown lengthening surgery. It is
advised to use mouthwashes since mechanical plaque control is not possible due to the presence
of the wound. Thus, the present study aims to compare the effectiveness of Persica and Protact
mouthwash on gingival healing after crown lengthening surgery.
Materials and Methods: In this double‑blind clinical trial, 33 candidates were randomly divided
into three groups (n = 11). The first group used 0.2% chlorhexidine (CHX) mouthwash; the second
group used Persica mouthwash; and the third group used Protact mouthwash. Patients were followed
for 14 days and changes in their plaque index (PI), gingival index (GI), stain index (SI), tongue taste,
and color were recorded. Data were analyzed using SPSS V.22 using the Kruskal–Wallis, Wilcoxon,
and Chi‑square tests. The significance level was considered to be < 0.05.
Results: The PI decreases significantly after 14 days in the CHX group (P = 0.011), however, this
difference was not significant in the other two groups. Moreover, the GI and SI were not significantly
different in any of the groups (P > 0.05). The changes in the tongue color and taste were only
observed in the CHX group and patient dissatisfaction was higher in this group.
Conclusion: CHX is the gold standard for patients who have undergone clinical crown lengthening
surgery; nevertheless, considering its side effects and bad taste, Persica and Protact herbal
mouthwashes can be used in more sensitive and uncooperative individuals.
