The rarity of primary squamous cell carcinoma of salivary gland coupled with degree of morphological diversity of the salivary gland carcinomas make this group of lesions, one of the most interesting and challenging diagnosis in the head and neck region. Owing to clinical and the histological diversity, the histological examination of an entire specimen is needed for diagnosis. Although tumor grading is important, it is not an independent prognostic indicator; the diagnosis and management need careful consideration of clinical and pathological features together. There are very few reports of this tumor originating in the submandibular gland. The present article reports the rare case of primary squamous cell carcinoma of submandibular gland in a 58-year-old male with brief review.

Purpose: The intention of this study was to compare the efficacy of eyelet wiring and direct interdental (Gilmer) wiring for achieving intermaxillary fixation (IMF). Materials and Methods: This study was a prospective randomized clinical trial. The study sample was derived from the population of patients who underwent IMF at the Department of Oral and Maxillofacial Surgery, Sharad Pawar Dental College, Wardha, India, between October 2008 and September 2010. The time required for placement and removal (in minutes) was compared between the eyelet wiring and direct interdental wiring techniques. Postoperative stability after achieving IMF was analyzed in the 2 groups. The plaque accumulation in both groups was evaluated using the Turesky-Gilmore-Glickman modification of the Quigley-Hein plaque index. Complications in the form of soft tissue injury, glove puncture, and trauma to the operator's finger were also recorded. Statistical analysis was performed with SPSS statistical software for Windows, version 8.0 (SPSS, Chicago, IL) using the χ 2 test and Student t test. Results: The mean working time for placement and removal of eyelet wiring (group I) was 18.00 minutes and 9.67 minutes, respectively. For direct interdental wiring (group II), it was 30.50 minutes and 23.12 minutes, respectively. The mean plaque index values were 1.78 and 2.54 for groups I and II, respectively, which signifies a higher plaque deposition in group II. No occlusal disturbance was seen in either group. The incidences of glove perforation, soft tissue trauma, and trauma to the operator's finger were higher in group II. Conclusions: Eyelet wiring is preferable to direct interdental wiring as evidenced by fewer complications, and requires a shorter operating time in patients with minimally displaced fractures. © 2012 American Association of Oral and Maxillofacial Surgeons.

Nitric oxide (NO), a short-lived, endogenously produced gas, plays key role in various physiological as well as pathological processes. NO-inducing cell signaling events within the cell producing it and the diffusibility of it in other cells have led to the discovery of various physiological functions of NO including vasodilation, respiration, cell migration, immune response and apoptosis. On the other hand, excessive and unregulated NO synthesis has been implicated in many pathophysiological conditions including cancer. Research on NO, during the past few years is one of the growing areas in cancer biology. The high incidence of oral cancer and precancer has been linked with habits of tobacco chewing and smoking and NO has been said as the "messenger of death" in tobacco related diseases. NO seems to play a part in various stages of carcinogenesis from initiation to progression. However, there is considerable controversy and confusion in understanding its role in cancer biology. It is said to have both, tumoricidal as well as tumor promoting effects and these depend on its timing, location and concentration. Further, NO has also been shown to have antitumor, chemopreventive and therapeutic abilities. Here is an overview in which efforts are made to understand the role of this molecule in oral carcinogenesis. © 2012 Elsevier Ltd. All rights reserved.

Purpose: The aim of this study is to see the efficacy of maxillomandibular fixation (MMF) screws with arch bars and to compare the plaque index in between 2 methods of MMF. Materials and Methods: This study is a randomized clinical trial. The study sample was derived from the population of patients who reported to Department of Oral and Maxillofacial Surgery, Wardha, Maharasthra, India between October 2006 and September 2008 and who required MMF. The patients were assessed for the time required in minutes for the placement and removal of screws and arch bar. Postoperative stability after achieving the MMF of both groups was analyzed and the plaque that was accumulated in both groups was evaluated by using TURESKYGILMOREGLICKMAN modification of the QUIGLEYHEIN plaque index. Statistical analysis was performed with SPSS statistical software for Windows, version 8.0 (SPSS, Inc, Chicago, IL) using the χ 2 test and Student t test. Results: The average working time for placement and removal of MMF screws is 18.67 minutes and 10.20 minutes, respectively, and for arch bars is 95.06 minutes and 29 minutes, respectively. The mean value of plaque index in group I is 1.88 and in group II is 2.69. It signifies that plaque deposition was more in group II. No occlusal disturbance was seen in both groups. Incidence of MMF screws causing damage to tooth root is 5.81% and incidence of screw breakage was seen in 3.33% of patients. Conclusions: Oral hygiene maintenance is better in patients with MMF screws than with arch bars with fewer complications and less operating time. Erich arch bars are the preferred choice in patients who require long-term MMF, because the screws start loosening after 5 to 6 weeks. © 2011 American Association of Oral and Maxillofacial Surgeons.

Development of cancer in humans is a multistep process. Complex series of cellular and molecular changes participating in cancer development are mediated by a diversity of endogenous and exogenous stimuli and important amongst this is generation of reactive oxygen species (ROS). Reactive radicals and non-radicals are collectively known as ROS. These can produce oxidative damage to the tissues and hence are known as oxidants in biological system. Many researchers have documented the role of ROS in both initiation and promotion of multistep carcinogenesis. To mitigate the harmful effects of free radicals, all aerobic cells are endowed with extensive antioxidant defence mechanisms. Lowered antioxidant capacity or the oxidant-antioxidant imbalance can lead to oxidative damage to cellular macromolecules leading to cancer. Oral cavity cancer is an important cancer globally and tobacco is the primary etiological factor in its development. Tobacco consumption exposes the oral epithelium to toxic oxygen and nitrogen free radicals that can affect host antioxidant defence mechanisms. Elevated levels of ROS and Reactive Nitrogen Species (RNS) and lowered antioxidants are found in oral precancer and cancer. Protection can be provided by various antioxidants against deleterious action of these free radicals. Treatment with antioxidants has the potential to prevent, inhibit and reverse the multiple steps involved in oral carcinogenesis. This review is an attempt to understand the interesting correlation between ROS and RNS mediated cell damage and enzymatic and non-enzymatic defence mechanisms involved in oral cancer development and its progression and the use of antioxidants in oral cancer prevention and treatment. © 2013 Elsevier Ltd.
