Background. Smokeless tobacco (SLT) as a drug substance has been used throughout the world although it has dangerous effects on human health. Among the 28 known carcinogens in SLT, tobacco-specific nitrosamines are considered to be the most potent. This has challenged the metabolic condition leading to a rise in the inflammatory status, increased apoptosis, and red blood cell (RBC) membrane damage. Therefore, the present study was undertaken to evaluate the adverse effects of SLT on hematological parameters and establish a correlation between them. Materials and Methods. A total of 100 subjects (50 SLT users and 50 nonusers) were selected for the study. Complete demographic data and history were taken and clinical examination was done to evaluate any oral mucosal changes. Venous blood samples were taken to analyze the hematological parameters. Results. Significant changes were observed in the complete blood profile in SLT users when compared to nonusers. All the hematological parameters had a negative correlation with form of SLT except for total leucocyte count which had a positive correlation. Conclusion. The current study confers an imperative role into SLT mediated effects on a complete hemogram and might be beneficial in spreading awareness against its usage. It also serves as a forewarning alarm among the population consuming SLT as an alternative to smoking tobacco.

This study points to the effectiveness of levamisole as an effective adjunct therapy in the routine management of RAU.

Cemento-ossifying fibroma (COF) is considered a benign osseous tumor. Herewith, we present a case of multiple central ossifying fibroma in a 35-yeaold woman. Intraorally, there was swelling in the left upper posterior teeth region and another diffused swelling in the fourth quadrant. Radiographs revealed the presence of well-defined mixed radiolucent–radiopaque area having thin radiolucent rim followed by thick sclerotic margin. No genetic correlation could be established. As bilateral COF is a rare entity, we present such a case with different radiographic appearance, using various radiographic techniques.

Ossifying fibromas are well-demarcated benign fibro-osseous tumors of craniofacial skeleton most often in the jaws. It has two types, conventional and juvenile ossifying fibroma (JOF). JOF is considered a separate entity from ossifying fibroma due to its locally aggressive behavior and tendency to occur at a young age. Two subtypes of JOF, i.e., juvenile psammomatoid ossifying fibroma (JPOF) and juvenile trabecular ossifying fibroma have been identified on the basis of histology 70% of the JPOF occur in the paranasal sinuses, 20% in the maxilla and only 10% in the mandible. Here, we report a case of JPOF in a 14-year-old girl causing an asymptomatic expansile swelling in the right mandibular posterior region, which is a rare site for this tumor.

Background:Macrophages are important cells for the innate immunity. Circulating monocytes are attracted to tissues by chemotactic factors and become macrophages under the influence of their microenvironment. Several studies suggested that local and systemic upregulation of fibrogenic cytokines and downregulation of antifibrotic cytokine are central to the pathogenesis of oral submucous fibrosis (OSMF). Currently, there have been no attempts made to elucidate the presence and role of macrophages in OSMF.Aim:Our aim was to study the expression of CD68 in OSMF patients and to investigate the possible correlation of macrophages using CD68 in various histopathological grades of OSMF.Subjects and Methods:A prospective case–control study which included 40 patients was conducted after obtaining informed consent and Ethical Committee clearance. Ten cases were normal control and thirty cases had OSMF. Biopsy was performed and a quantitative study of macrophages was done using CD68 antigen and was immunohistochemically localized. Statistical analysis was carried out using the Statistical Package for Social Sciences (SPSS) 17.0 version (SPSS Inc., Chicago, IL, USA).Results:OSMF was observed in male patients of a younger age group. The macrophage number in the patients of intermediate and advanced stage of OSMF was higher than that of the controls which was statistically significant (P < 0.05).Conclusion:The findings of this study suggest that CD68 plays a vital role in the pathogenesis of OSMF and can be regarded as a useful marker for assessing the progress of the disease.

Objectives: Pericoronitis of mandibular third molars is commonly encountered in our day to day practice. Most of the case extraction becomes mandatory. This study was carried out to find the incidence of periodontitis on the distal aspect of the second molar adjacent to impacted third molar. Materials and Methods: A total of 400 patients were included in the study. Patient selection was randomly done. Whoever came with a chief complaint of pain in the third molar area were included in the study. They were evaluated both clinically and radiographically with an orthopantomogram. Patients' age, gender, type of impaction, presence or absence of bone loss, type of bone loss, and presence or absence of caries was evaluated radiographically and noted. Results: Periodontitis was observed in 39% of the cases and caries in 26% of the cases. Conclusions: These percentages are alarming and could be used to prophylactically extract the impacted third molars and thereby promoting the oral health of the individual.
