Association of tissue eosinophilia with oral squamous cell carcinoma has shown variable results ranging from favourable to unfavourable or even having no influence on prognosis. Also, very few studies have been done to know the role of eosinophils in premalignancy. So the present study investigated role of eosinophilic infiltration in oral precancer and cancer and its possible use as a prognosticator. 60 histopathologically proven cases (20 cases each of metastatic and nonmetastatic oral squamous cell carcinoma and oral leukoplakia with dysplasia of various grades) were included. Congo red is used as a special stain for eosinophils. Each specimen slide was viewed under high power in 10 consecutive microscopic fields for counting of eosinophils. As a result, a significant increase in eosinophil count was found in oral carcinomas compared to dysplasia. Nonmetastatic cases showed higher counts than metastatic carcinomas. So, it is concluded that eosinophilia is a favourable histopathological prognostic factor in oral cancer. Moreover, higher eosinophil counts in carcinoma group compared to dysplasia group proved that they might have a role in stromal invasion thus suggesting that quantitative assessment of tissue eosinophilia should become a part of the routine histopathological diagnosis for oral precancer and OSCC. © 2014 Megha Jain et al.

India has seen a large influx of refugee populations throughout history and the Tibetan immigration is one among them. Understanding the health status and needs of immigrants is imperative because of their growing numbers and their input to the health of the nation. The oral health professionals face many challenges while confronting refugees and immigrants from cultures different from their own. Earlier studies have shown that children, especially refugees and immigrants have had a higher prevalence of unmet oral health needs.The purpose of this study was to assess and compare the oral health status of 11-13 year old Tibetan and non-Tibetan school children in Bylakuppe, Karnataka, India.A stratified cluster sampling of 11-13 year old Tibetan and non-Tibetan school children (431 and 434 respectively) formed the study participants for this study. Assessment of dental caries, periodontal disease and malocclusion was done in accordance with criteria laid down by WHO in oral health assessment survey basic methods, 1997. Data was collected by a single trained examiner. The results obtained were analyzed by SPSS version 18. The data was statistically analyzed by using chi-square test and independent t test. The level of significance was set at 5%.The prevalence of caries was found to be higher among the Tibetan school children when compared to the non-Tibetan school children (71% and 53.9% respectively). The mean number of sextants with healthy gingiva (2.492.40) and calculus (1.632.28) was higher among the non-Tibetan school children. The mean Dental Aesthetic Index score was found to be higher for Tibetan school children than the non-Tibetan school children (26.574.62 and 23.524.36 respectively).The prevalence of caries, periodontal disease and malocclusion were found to be higher among immigrant Tibetan school children as when compared to non-Tibetan school children. The high level of unmet needs in the study population highlights the need for a comprehensive dental care programme in Bylakuppe.

Juvenile recurrent parotitis (JRP) is a nonobstructive, nonsuppurative parotid inflammation in young children. Causative factors are many such as allergy, infection, local autoimmune manifestations, and genetic inheritance have been suggested, but none have been proved. Parotid sialography is a hallmark in the diagnosis of JRP but newer modalities such as ultrasonography, computed tomography and magnetic resonance imaging-sialography are noninvasive investigative techniques. Recurrent attacks are often managed conservatively. Here we report a case of a 5-year-old child with JRP. Sailography can be used as both diagnostic and therapeutic modality.

To evaluate the effect of the probiotic BLISR K12 (Bacteriocin Like Inhibiting Substance) on the counts of Streptococcus mutans in the oral cavity. In this study 40 preschool children consisting of 16 girls and 24 boys were randomly selected. These children were divided blindly into a test and control group. The pre- salivary unstimulated saliva was collected in sterile salivary vials and subjected to microbiological assay to check for S. mutans counts for both groups. After introduction of probiotic in both groups post salivary samples were collected and again subjected to microbiological assay. A follow up collection of unstimulated saliva was done after 4 months again in both groups. A decreasing trend was seen in the S. mutans counts from pre to post salivary samples in the test group.The follow up results also showed a continual, statistically significant reduction in the counts in the test group. While in the control group there was no significant reduction. SK12 when used as a probiotic caused a significant reduction in the S.mutans count, follow up evaluation also showed a decliningtrend.

Background: Children with poor oral health are 12 times more likely to have restricted-activity days. Dental health education [DHE], with the objective of improving the oral hygiene of the participants, would have obvious merits. Objectives: To determine the effectiveness of school DHE, conducted at repeated and differing intervals, in improving oral health knowledge, practices, oral hygiene status, and the gingival health of schoolchildren belonging to two socioeconomic classes. Materials and Methods: This 36-week duration study assessed the effectiveness of school DHE conducted every three weeks against every six weeks on oral health knowledge, practices, oral hygiene status and gingival health of 415, 12- to 13-year-old schoolchildren belonging to social classes I and V. Of the three selected schools of each social class, one each was subjected to the intervention of either three or six weeks or was a control, respectively. Oral health knowledge and practices were evaluated using a questionnaire. Oral hygiene and gingival health were assessed using plaque and gingival indices. Statistical Analysis Used: Friedman's test was used for the longitudinal analysis of data. ANOVA and Student's t test were used for continuous data. Results: Plaque and Gingival score reductions were highly significant in intervention schools, and were not influenced by the socioeconomic status. When oral health knowledge was evaluated, highly significant changes were seen in intervention schools; more significantly in schools receiving more frequent interventions. The socioeconomic status influenced the oral hygiene aids used and the frequency of change of toothbrush. Controls showed no significant changes throughout. Conclusions: The DHE program conducted at three-week intervals was more effective than that conducted at six-week intervals in improving oral health knowledge, practices, oral hygiene status, and gingival health of schoolchildren.

Trauma to the anterior teeth affects the esthetic and psychological well-being of the patient. Advancement in the adhesive dentistry has facilitated the restoration of the coronal tooth fractures by minimally invasive procedures when the original tooth fragment is available. Reattachment of fractured fragment offers immediate treatment with improved preponderant aesthetics and restoration of function. Here, we describe a case of complicated fracture of the maxillary left immature permanent central incisor, which was treated endodontically followed by esthetic reattachment of the fractured fragment using the glass fiber post. Functional demands and esthetic considerations of the patient were fully met with this biologic mode of fragment reattachment.

OBJECTIVE: To evaluate the morphometry of AgNORs in odontogenic cysts and to compare their biologic behavior to determine whether AgNOR morphometry is helpful in predicting the behavior. STUDY DESIGN: Ten cases each of odontogenic keratocyst (OKC), dentigerous cyst (DC) and radicular cyst (RC) were stained with silver nitrate. Morphometric analysis of 100 selected epithelial and connective tissue cells was done to record their nuclear volume, nuclear perimeter, contour index of the nucleus, AgNOR count, AgNOR proportion and single AgNOR volume. The results were statistically analyzed using ANOVA. RESULTS: AgNOR count, nuclear volume and nuclear perimeter were greatest in the OKC followed by DC and RC, suggesting that these parameters differentiate between the aggressive and less aggressive odontogenic cysts. Single AgNOR volume and AgNOR proportion were greatest in the RC followed by OKC and DC, respectively. CONCLUSION: Results of our study taken in isolation point to AgNOR count as the most reliable factor in differentiating between aggressive and nonaggressive odontogenic cysts.

Context: Previous studies have reported that the dental follicular tissues associated with impacted lower third molars (ILTMs) may undergo cystic degeneration and/or neoplastic transformation. This is especially likely when the pericoronal space is >2.5 mm on intraoral radiographs and >3 mm on panoramic radiographs and to examine dental follicular tissue for pathological changes in patients with ILTMs and pericoronal radiolucencies of <2.5 mm. Aim: Histopathological evaluation of follicular tissues associated with ILTMs. Materials and Methods: The morphology of the hematoxylin and eosin-stained follicular tissues of 146 such impactions were studied. Results: On microscopy, no cystic structures with fibrous walls were identified. 85 cases (58%) showed fibrous or myxomatous connective tissue and no epithelial elements. 61 cases (42%) showed epithelial elements in addition to fibrocollagenous tissue. Of these, 16 cases exhibited epithelium, of which 13 cases showed reduced enamel epithelium and three cases showed squamous metaplasia/non-keratinized stratified squamous epithelium. Conclusions: All asymptomatic unerupted third molars with pericoronal radiolucency of <2.5 mm should be retained since they do not exhibit cyst formation microscopically.

This study compares the internal fit and marginal adaptation of copy milled Zirconia copings with Nickel-Chromium (Ni-Cr) copings fabricated using a lost wax technique before and after ceramic veneering. A standardized metal master die simulating a prepared crown was fabricated and twenty impressions of the metal die were made and poured with die stone. Wax patterns were made on ten dies and cast while light cure resin patterns were made on the other ten dies for copy milling the Zirconia copings. Five specimens from each group were subjected to ceramic veneering. All the test specimens were luted on to the fresh dies, embedded in dental plaster, sectioned and image analysis done using scanning electron microscopy. Thereafter statistical analysis is done using student t-test. The linear measurements for internal fit and marginal discrepancy were increased for Zirconia compared with Ni-Cr copings. The difference in the values of all the specimens of all the groups were not statistically significant (P > 0.05) except the values comparing the internal fit of Zirconia and Ni-Cr copings before ceramic veneering (P < 0.001) which was statistically significant. The internal fit and marginal adaptability of Ni-Cr copings were found to be better than the Copy milled Zirconia copings but internal fit and marginal adaptability deteriorated after ceramic veneering.

Epidermoid cysts represent the most common cutaneous cysts. While they may occur anywhere on the body, they occur most frequently on the face, scalp, neck, and trunk.Dermoid and epidermoid cysts are developmental pathologies that occur in the head and neck with an incidence of 6.9-7%.1,2 Historically, epidermoid cysts have been referred to by various terms, including follicular infundibular cysts, epidermal cysts, and epidermal inclusion cysts. Because most lesions originate from the follicular infundibulum, the more general term epidermoid cyst is favored. The main reason why some people want them removed is for cosmetic reasons as they can look unsightly. We are presenting a rare case of non hereditary multiple epidermoid cysts present only on the scalp, of a 48 year old female.
