Evaluation of Gingival Status in Orthodontic Patients by Three Different Mouthrinses – Anti-Oxidant, Essential Oil and Chlorhexidine - A Randomised Control Trial

Abstract

Objective: To evaluate the clinical efficacy of an antioxidant mouth wash on fixed appliance orthodontic patients with generalized gingivitis. The mouthrinse contains the antioxidants ferulic acid and phloretin.

Materials and Methods: A total of  eighty one  patients  undergoing fixed   orthodontic appliance therapy participated in the study were divided into three active interventional groups of n=27 each. Group I were given antioxidant mouthwash, group II with essential oil mouthwash and group III with chlorhexinde mouth wash were given as a interventional measure immediately after bonding of the brackets.  Each patient was evaluated at  four orthodontic treatment visits (T0, T1, T2, T3)for 3 months. Between T2 and T3, intervention was with withdrawn.  A periodontal examination, including Gingival index (GI),  Bleeding on probing (BOP), and Orthodontic plaque index (OPI) was performed at each visit. The severity of index scores was assessed by Repeated measure ANOVA followed by Post-hoc Bonferroni test and Tukey test.

Results: Gingival index:Mean differences across the three time points T1, T2 and T3 for GI in all the three groups (T2-T1: 1.03±0.35, 0.47±0.2, 1.17±0.37 and T3-T2: 1.2±0.35, 0.45±0.18, 1.65±0.24 respectively) showed a statistically significant difference (p<0.001). No statistical difference is observed for  Bleeding on probing between the groups across different time periods.

 Conclusion:  Antioxidant-mouthwash equally effective as essential and Chlorhexidine mouthwashes in  reducing severity of gingivitis in early stages of fixed  orthodontic appliance therapy.
