Clinicobiochemical evaluation of turmeric with black pepper and nigella sativa in management of oral submucous fibrosis-a double-blind, randomized preliminary study.

OBJECTIVE

To investigate the effectiveness of turmeric with black pepper and nigella sativa in oral submucous fibrosis (OSMF).

STUDY DESIGN

Forty OSMF patients were randomly divided into two groups. The study was performed under a double-blind, randomized design. Group A received turmeric with black pepper and group B received nigella sativa for 3 months. Clinical evaluation was done every 15 days. Patients' serum superoxide dismutase (SOD) levels were assessed before and after treatment and also compared with healthy controls. The response to treatment was analyzed using analysis of variance, paired t test, and unpaired t test.

RESULTS

After the treatment, groups A and B showed 3.85 ± 0.22 mm and 3.6 ± 0.07 mm improvement in mouth opening, respectively (P < .01); 87.90% and 78.91% reduction in burning sensation, respectively (P < .01); and +0.62 U/mL and +0.74 U/mL improvement in serum SOD levels, respectively (P < .05). The maximum mouth opening achieved was 8 mm in group A and 7 mm in group B. The mean pretreatment SOD level for controls and patients was 3.61 ± 0.24 U/mL in group A and 2.63 ± 0.18 U/mL in group B.

CONCLUSION

Turmeric with black pepper and nigella sativa improved mouth opening, burning sensation, and SOD levels in the present OSMF study patients; however, further investigations are needed.
