Evaluation of the Histological Changes in the Structure of the Minor Salivary Glands in Patients With Oral Submucous Fibrosis (OSMF)

Background: The minor salivary glands (MSGs) are critical components of the mouth's delicate environment. The pre-malignant changes of oral submucous fibrosis (OSMF) have been associated with a decline in the quality of life and an uptick in the prevalence of oral malignancies. Aim: The aim was to provide evidence of the histological alterations in minor salivary gland structure seen in individuals with OSMF. Methods and materials: A total of 106 confirmed cases of OSMF were enrolled in the study. In order to perform an incisional biopsy, we first collected the patient's complete demographic and clinical history. Using a Vernier calliper, the inter-incisal distance was used to evaluate( )the mouth opening of the patients. An incisional biopsy of the buccal mucosa was carried out using a 6 mm diameter punch and local anaesthesia. After the appropriate demographic and medical information had been gathered. Acinar cells and the surrounding stroma of tissue slices were observed under a light microscope for alterations. The cytoplasm, nucleus morphology, cellular shape, mucin pooling, and acinar outline of acinar cells were all examined by the researchers. It was taken into account to classify OSMF histologically based on variations in juxta epithelial hyalinization. Results: Multiple aetiologies for the symptoms of OSMF were reflected in the patient's histological abnormalities in the minor salivary glands. On the measurement of the diameter of acini, we discover that the average area of salivary gland acini in OSMF patients is smaller than in the normal group indicative of a decrease in size. The number of functional acini in OSMF is fewer than compared in the control group. Conclusion: Because of the findings of this study, we now have a better understanding of the factors that play a role in the incidence of dryness of the oral and pharyngeal mucosa (OSMF), although it has to be mentioned that no major impact of OSMF on minor salivary glands was observed in our study.
