Isolation of polycrystalline ferroelectric compound from Cycas revoluta

Introduction: Oral cavity is one of the most commonly accessible sites for tumor and tumour like lesions with more prevalence for benign lesions than malignant with male preponderance. Aim: To study the spectrum of oral cavity lesions in relation to age , sex and site. Results: A total of 473 cases were included in the present study. Out of these, 263(55.6%) were males and 210 (44.39%) were females with Male: Female ratio of 1.5:1. Tongue 177 (37.4%) was the most common site closely followed by tonsils 175(36.9%), Buccal Mucosa 52 (10.9%), Lip 36 (7.6%), Minor salivary glands 14(2.9%) floor of mouth 11 (2.3%), Palate 9 (1.9%) and retro-mandibular/ post ramal (1.4%). Neoplastic lesions accounted for 11.4% cases and non neoplastic lesions for 88.5%. Benign neoplasia accounted for 37% of the total neoplastic lesions and malignant lesions constituted 62.9%. Squamous cell carcinoma being the most common malignant lesion (70.5%). Conclusion: Due to their high malignant potential and overlapping clinical features, histopathological typing of the various lesions is mandatory to confirm the diagnosis.
