Introduction: Oral field cancerization implies that oral cancer does not arise as an isolated cellular phenomenon but rather as an anaplastic tendency involving many cells at once and results in the multifocal development of cancer at various rates within the entire field in response to a carcinogen especially tobacco. This concept has been frequently used to explain the occurrence of multiple primary cancers and recurrences following complete excision of oral cancer. Discussion: This review deals in detail with the origin, principle, various theories used to explain this effect and molecular, genetic, as well as cytogenetic findings related to oral field cancerization. Further, the clinical implications and future research directives are also discussed. © 2012 Springer-Verlag. Source

Introduction: Pregnancy gingivitis is a major oral infection. Periodontium acts as a reservoir of inflammatory mediators and sub gingival biofilms of bacteria. Aim: To evaluate the anaerobic oral microbial flora in pregnant women before delivery and after delivery by comparing them with control group. Material and Methods: The study group included fifteen cases of pregnant women before and after delivery and healthy non- pregnant women of same age as control group. Sub gingival plaque samples were collected with the help of dentists. The samples were inoculated immediately into Thioglycollate broth (MV010), transported to the laboratory, inoculated on to selective media for anaerobes (Hi-media laboratories) incubated anaerobically (Gas pack).Results: Prevotella, Tanerella forsythia, Porphyromonas gingivalis and Fusobacterium nucleatum, Veillonella, Peptostreptococcus were isolated. Discussion: The anaerobic bacteria in pregnant women were Prevotella, Tanerella forsythia and Porphyromonas gingivalis. Viellonella and Peptostreptococcus were seen in control group and after delivery. Research suggests that periodontal pathogens may travel the blood stream from the oral cavity to the placenta. Conclusion: Pregnancy has significant effect on periodontal tissue. There is a significant alteration of bacterial flora during and after pregnancy. Oral health has to become a part of antenatal care /check up. Source

Probiotics are dietary supplements containing potentially beneficial bacteria or yeasts. They are administered in different quantities that allow for colon colonization. These products help in stimulating health promoting flora and also suppressing the pathologic colonization and disease spread. The use of probiotic plays an important aspect in dentistry too ever since the oral infections occupied the prime space among the other infections effecting the humans. This concept of microbial ecologic change both for medical and dental changes has accumulated a lot of evidence in recent times. But to date, no substantial literature and use has been postulated. There are claims that probiotics strengthen the immune system to combat allergies, stress, exposure to toxic substances and other diseases. There are reports of their beneficial use in HIV infection and cancers, mostly, the colo-rectal carcinomas. Their use in pre malignant and malignant oral disorders is yet to be probed. Strains of genera lactobacillus and bifidobacterium are the most widely used probiotic bacteria. This review is an attempt to discuss briefly the role of probiotics in medicine and dentistry. © JAPI.

Introduction: Pulpotomy technique basically consists of removing the coronal pulp and fixing the radicular pulp with a medicament. It is the most widely accepted clinical procedure for treating primary teeth with coronal pulp inflammation caused by caries with no involvement of the radicular pulp. Aim: To evaluate the success and efficacy of Mineral Trioxide Aggregate (MTA), Lasers and Biodentine as pulpotomy agents both clinically and radiographically. Materials and Methods: In the present study, 60 primary molars in children whose pulpal status warranted pulpotomy were selected and randomly assigned into three groups that included MTA, Laser and Biodentine allocating 20 teeth to each group. The pulpotomy procedure was then performed on all selected teeth followed by restoration with stainless steel crowns. Later the patients were recalled for 3 months and 6 months for clinical and radiographic evaluation. Results: Statistical analysis was done using Fisher exact test to determine pair wise comparison of three agents with respect to clinical and radiographic criteria. Kruskal-Wallis ANOVA, Mc Nemars test was applied to evaluate the efficacy of each agent between 3 months and 6 months. The results showed that maximum success rate was found in MTA group. However, the comparison between three groups was statistically not significant (p>0.05). Conclusion: Pulpotomies performed with either MTA, Laser or Biodentine are equally efficient with similar clinical/radiographic success and hence can be considered as alternatives to Formocresol. © 2015, Journal of Clinical and Diagnostic Research.

Introduction: Glut-1 is a glucose transporter protein, the expression of which is upregulated in malignant cells which show increased glucose uptake. Alterations in expression of Glut-1 have been reported in several pre-malignant and malignant lesions. The objectives of the present study were to compare the expression of Glut-1 in normal persons and in patients with oral squamous cell carcinoma (OSCC), to correlate the expression of Glut-1 with respect to clinical staging of OSCC and to evaluate the expression of Glut-1 with respect to different histopathological grades of OSCC. Materials and Methods: Thirty cases of OSCC were staged clinically and graded histopathologically. Immunohistochemical method was used to detect the expression of Glut-1 in OSCC and the same was compared with the normal subjects. The scores were compared using the chi-square test. Results: Glut-1 expression was detected in all grades of OSCC. A significant correlation with a P value of 0.00004 was found in immunostaining between normal and OSCC. The expression of Glut-1 was significant when compared with different clinical stages with significant P value of 0.0004 and in different histopathological grades of OSCC with a P value of 0.00001. Conclusion: Higher immunohistochemical staining scores were obtained with increased clinical staging and histopathological grades of OSCC. High expression of Glut-1 may be related to poor prognosis in OSCC. © 2014, Medknow. All rights reserved. Source
