Significance of Pulmonary function test in Oral Submucous Fibrosis: A need of the hour

Abstract

Introduction:
The study aims to measure and compare pulmonary function tests (PFTs) in oral
submucous fibrosis (OSMF) patients (smokers/nonsmokers) and normal
individuals.
Materials and methods:
The study population included 180 participants that comprised 60 nonsmoker
OSMF patients, 60 OSMF patients who smoke as well, and 60 patients with no
deleterious habits. Spirometer was used to assess PFT.
Results:
Results showed that a significant P value was obtained for forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC, peak expiratory flow rate (PEFR), and maximum voluntary ventilation (MVV) and also for the predicted values of FEV, FEV1, FEV1/FVC, PEFR, and MVV in OSMF (smokers/nonsmokers) study groups

Conclusion:
Thus, the decrease in pulmonary function can be an alarming sign for restrictive
type of pulmonary disease.
