Oral cancers often occurs out of long standing potentially malignant lesions and conditions so called premalignant lesions and conditions. Oral precancer is a intermediate state with increased cancer rate which can be recognized and treated obviously with much better prognosis than a full blown malignancy. Oral cancer risk can be lowered or even prevented by simply understanding basic oral hygiene, different bacteria found in the mouth, and how diet influences oral cancers. Currently, research is being done on the relationship between diet and oral cancer. Oral cancer is a very serious disease that can be prevented. Practicing good oral hygiene is key to help keep the oral cavity clean. Limiting the use of tobacco and alcohol products is also important because these are the causes of most oral cancers. Lastly, eating a well balanced diet that has protective affects can reduce the risk of oral cancer. This includes a diet high in fruits, vegetables, and fish and low in high fat and cholesterol meats, rice, and refined grains.

Background: Third molar surgey always needs primary intervention as it can lead to various complications and pathologies. Considering other ways for postoperative anesthesia it was infered that submucosal group which showed simple injection technique and direct surgical site administration is more beneficial. It was noticed as a patient comfort method which can be the preferred as the drug of choice over intravenous route of dexamethasone injection. Introduction: Impaction of third molar is a common affliction and surgical removal is the only treatment option. The post-operative sequelae following the third molar surgery are pain, edema and trismus. The use of corticosteroids is to counteract it via various routes. Still, controversy exists in the literature regarding the administration of corticosteroids over the routes and time of administration. The purpose of this study was to compare the postoperative pain, edema and trismus following third molar surgery while using preoperative intravenous and submucosal routes of dexamethasone, in terms of pain, facial swelling, and trismus. Materials and Methods: This study consisted of 64 patients presented with mesioangular impacted mandibular third molar for surgical removal. Preoperative measurements of edema, trismus were analyzed. Postoperative pain was estimated using visual analogue scale. Edema was assessed by the extra oral facial measurements. Trismus was measured by recording the interincisal opening in millimeters. Dexamethasone was administered intravenously or submucosally according to the choice of operating surgeon and were divided into 2 groups. Results: Mean and standard deviation calculated for continuous variables. Changes in parameters was analysed using t test and Mann–Whitney U test. Here, submucosal group were reported with increased pain on the second postoperative day. On seventh postoperative day mean value turns to 0.7 ± 1 for submucosal and 0.6 ± 1.2 for intravenous group. On overall observation, intravenous group expressed statistically significant ( P < 0.01) reduction in pain compared to the submucosal group during immediate and second postoperative days. Conclusion: Analyzing the previous studies, and from the experience of the present one, it could be reasonably found out that administration of submucosal dexamethasone is beneficial for overall patient compliance.

Both tongue coating removal methods evaluated were efficient in reducing mutans streptococci level. This implies that physical removal of the coating on the dorsum of the tongue is important and not the method used for the same.

SUMMARYExtranodal non-Hodgkin lymphoma (NHL) is infrequent in the oral cavity and constitutes 3.5% of oral cancers, and less than 2.2% of maxillofacial lymphomas. Diffuse large B cell lymphoma (DLBCL) accounts for 40% of NHL and has a 5-year survival rate of less than 30%. Early detection of extranodal NHL by dental personnel is extremely important as a delay in diagnosis can result in the cancer being diagnosed at an advanced stage and a poor prognosis. A 60-year-old male presented with an uncharacteristic asymptomatic rapidly enlarging swelling of the anterior maxilla, which on histopathological and immunohistochemical analysis was diagnosed as DLBCL. Imaging studies showed bone invasion and lymph node metastasis with poor prognosis. The patient received radiotherapy and chemotherapy but died within 3 months of diagnosis. A literature search revealed one another case with anterior maxilla occurrence, as the few oral DLBCL so far reported have appeared on the posterior palate or other intraoral sites. BACKGROUND

Wound healing plays an important role in the success of any surgical procedure, such as extractions, and the hemocoagulase system may act as a hemostatic agent and a promoter of wound healing.
