Relation of Salivary MMP-8 with Oral Submucous Fibrosis and Oral Squamous Cell Carcinoma: a Cross Sectional Analytical Study
Overview
Affiliations
Objectives: We aim to evaluate salivary matrix metalloproteinases (MMP-8) levels in oral submucous fibrosis (OSF) and oral squamous cell carcinoma (OSCC) for the purpose of diagnosis at the early stage via non-invasive method.
Setting: The study was multicentre, carried out at a tertiary care hospital in Karachi, Pakistan.
Participants: A total 60 participants of any age, sex and ethnicity were randomly selected for the purpose of this study. Patients demonstrating clinical evidence of OSF and biopsy-proven cases of OSCC were included. Patients with indeterminate histopathological report, immunodeficiency, autoimmune disorder, chronic medical and periodontal disease (periodontal depth greater than 5 mm) and individuals with interincisal mouth opening greater than 35 mm were excluded from the study.
Interventions: Salivary MMP-8 levels were observed in OSF, healthy and OSCC groups by using ELISA. One way analysis of variance was applied to establish whether MMP-8 levels of disease-free individuals and patients suffering from OSF and OSCC differed from each other.
Results: Statistically significant difference in salivary MMP-8 expression in diseased and control group was observed. MMP-8 levels in OSCC (0.64 ng/mL) and OSF (0.66 ng/mL) were underexpressed as compared with healthy participants (7.9 ng/mL).
Conclusion: MMP-8 levels were underexpressed in OSCC and OSF patients as compared with controls, which imply that MMP-8 level has an inverse relation with OSCC and OSF.
