Estimation of the Salivary Copper Levels in Oral Submucous Fibrosis Condition: An In Vivo Study

Abstract

Aim: The aim of the present study was to estimate the salivary copper levels in oral submucous fibrosis (OSMF) condition.

Materials and methods: A total of 60 individuals of which an equal number of 30 each in normal healthy control group as well as in clinically and histopathologically (the biopsy was done once after the clinical confirmation of OSMF in the patient) confirmed patients of OSMF were included in the study group. Total of 51 males and 9 females were considered for the present study and the age distribution of these groups ranged from a minimum of 21 years to a maximum of 74 years. Unstimulated whole saliva was collected from the patient followed by the conventional biopsy practice. The collected saliva was then subjected for the analysis of copper levels. Trace element copper was estimated by using Digital Semiautomatic Analyzer with the help of copper kit. The clinical mouth opening of OSMF was estimated. Analysis of variance (ANOVA) and Tukey HSD post hoc test was used analyze the data wherein the participants were grouped into age ranges of 20-30, 31-40, 41-50, and >60 years.

Results: The mean salivary copper level among OSMF and control groups with respect to age in 20-30 years was 55.98 ± 15.50 and 30.87 ± 7.70, in 31-40 years was 63.96 ± 21.13 and 32.95 ± 4.56, in 41-50 years was 50.11 ± 6.83 and 30.46 ± 3.28, and >60 years was 45.65 and 13.67 µg/dL, respectively. The mean salivary copper levels among OSMF and Control groups with respect to males were 55.60 ± 15.27 and 31.18 ± 6.97 and among females were 67.0 ± 24.25 and 30.06 ± 5.77 µg/dL, respectively. The mean salivary copper levels with histopathological grades in very early stage was 47.18 ± 5.73, in early stage was 49.22 ± 7.65, in moderately advanced was 73.53 ± 10.62 and in OSMF with mild dysplasia was 79.98 ± 16.27 µg/dL, respectively. The mean salivary copper levels in individuals with clinical mouth opening more than 35 mm was 45.65 ± 6.57, in 25-35 mm was 48.94 ± 21.60, in 15-25 mm was 70.54 ± 3.52 and in less than 15 mm was 81.50 ± 16.66, respectively.

Conclusion: The present study concluded that salivary trace element levels could be used as potential diagnostic and prognostic markers in patients with OSMF.

Clinical significance: Trace elements are involved in many different physiological and metabolic processes in humans, either directly or indirectly. Copper is involved in vital biochemical activities like different redox and free radical formation and in maintaining cellular proton homeostasis. It is also associated with the processing of oxygen and a component of arecanut in all forms, which is implicated in the etiology of OSMF. How to cite this article: Gupta R, Jayanti I, Das A, et al.
