Lipoma is a painless soft tissue tumour of the mesenchymal origin, which is slow growing and well circumscribed. The occurrence of lipoma is rare in the oral cavity (1-4%); however, the frequency is much higher in the head and neck region. The tumour is mostly present in the buccal mucosa, lips, tongue, palate, buccal sulcus and floor of the mouth. Sometimes the tumour becomes large enough to cause difficulty in speech and mastication. Histologically, lipoma is composed of mature fat cells, surrounded by normal fat. We present two cases of intraoral lipoma in two female patients.

Pyogenic granuloma (PG) is a kind of inflammatory hyperplastic soft tissue lesion of the oral cavity. The lesion, however, is not related to infection and arise as a reactive growth in response to various stimuli. It has a very high vascularity because of the presence of numerous prominent capillaries. The lesion has a bleeding tendency, even after a minor traumatic episode, such as during mastication. Bleeding may be at times very severe and difficult to control. We present the case of a profusely bleeding young PG in a young teenage child.

Oral submucous fibrosis (OSMF) is an insidious chronic progressive disease of the oral cavity which is considered as a precancerous condition. The suggested aetiological factor is the practice of certain customs/habits of the inhabitants of South East Asia. As the disease progresses, the oral mucosa becomes stiff due to the formation of fibrotic bands in the cheek, ultimately leading to reduced mouth opening and trismus. The early form of the disease can be treated by medicinal means, however, advance form needs surgical excision of the fibrotic tissue bands. The defect created due to the excision needs to be repaired by various grafts including split thickness skin grafting, bilateral nasolabial flaps, palatal island flaps, tongue flaps, buccal fat pad graft and temporalis muscle flap graft. We present the management of trismus following OSMF by various surgical approaches in three cases.

Introduction: Oral malignancy is usually preceded by lesions which are non-malignant to begin with and which are therefore been termed as premalignant. Many premalignant lesions and conditions like leukoplakia, erythroplakia, oral lichen planus, oral submucous brosis have malignant potentials. Aims: To evaluate the serum lipid prole in premalignant lesions and conditions like Oral Leukoplakia, Oral Submucous brosis and in Oral squamous cell carcinoma and its comparison with the lipid prole among control groups. Material and method: A total number of 225 patients were selected for the study from the OPD in Chandra Dental College and Hospital, Barabanki, U.P. the patients were selected under the criteria mentioned below. Patients with clinically evident and histopathologically conrmed with oral submucous brosis, oral lichen planus, oral leukoplakia, erythoplakia, and oral malignancy, for leukoplakia patients with histopathological conrmation sample collection was done, for patients with Oral Submucous Fibrosis after histopathological conrmation, sample collection was done and for Oral Malignancy sample collection was done after histopathological conrmation were included in this study. Result: In Control Group (1 Vs 3), the mean HDL (mean± s.d.) of patients was 72.9885± 8.6803. In Malignant Group (1 Vs 3), the mean HDL (mean± s.d.) of patients was 38.2000± 3.5106. Distribution of mean HDL with Group (1 Vs 3) was statistically signicant (p<0.0001). In Control Group (1vs3), the mean VLDL (mean± s.d.) of patients was 36.8640± 3.0412. In Malignant Group (1vs3), the mean VLDL (mean± s.d.) of patients was 26.1600± 1.5905. Distribution of mean VLDL with Group 1vs3 was statistically signicant (p<0.0001). In Control Group1 vs3, the mean LDL (mean± s.d.) of patients was 96.4448± 12.7468. In Malignant Group1 vs3, the mean LDL (mean± s.d.) of patients was 94.8000± 5.9233. Distribution of mean LDL with Group 1 Vs3 was not statistically signicant (p=0.3125). Conclusion: There was statistically signicant decrease in plasma total cholesterol, TG, LDL, VLDL and HDL observed in malignant patients as compared to the premalignant control group. The low lipid levels associated with Oral malignancy indicates that there is inverse relationship between oral cancer and serum lipid prole. Decrease in the lipid levels may be considered as a useful biochemical marker in the early diagnosis of oral malignancy.
