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 150 participants that comprised 50
nonsmoker OSMF patients, 50 OSMF patients who smoke as well, and 50 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.
