Objective: Angiogenesis or neovascularization has long been known to aid in progression and metastasis of malignant tumors. Tumor angiogenesis is a complex event mediated by angiogenic factors released from cancer cells and or by host immune cells. Mast cells may induce tumor progression and potentiate metastasis by stimulating angiogenesis. The purpose of the present study was to validate topographic distribution of micro vessel density (MVD) and mast cell density (MCD) and help to elucidate the possible role of mast cells in tumor angiogenesis and correlating this with advanced disease parameters. Study Design: MVD and MCD were investigated in tumor specimens from 30 patients diagnosed with different histologic grades of oral squamous cell carcinoma (OSCC). Intratumor vessels were stained with collagen Type IV antibody and mast cells with Toluidine blue before being measured by light microscopy. Results: There was a significant correlation between MVD and disease progression and number of blood vessels increased from well to poorly differentiated OSCC where as MCD decreased. Conclusions: These findings suggest that angiogenesis indeed occur in OSCC and might be used as an index to inflect the aggression of the disease however mast cells make up only a part of complex process of angiogenesis along with other factors secreted by tumor. © Medicina Oral S.

We wanted to assess oral and salivary changes in end stage renal disease (ESRD) patients undergoing hemodialysis (HD) and to understand the correlation of such changes with renal insufficiency. The cross-sectional study was performed among 100 ESRD patients undergoing HD. Among these, 25 patients were randomly selected to assess the salivary changes and compared with 25 apparently healthy individuals who formed the control group. Total duration of the study was 15 months. Oral malodor, dry mouth, taste change, increased caries incidence, calculus formation, and gingival bleeding were the common oral manifestations. The flow rates of both unstimulated as well as stimulated whole saliva were decreased in the study group. The pH and buffer capacity of unstimulated whole saliva was increased in the study group, but stimulated whole saliva did not show any difference. ESRD patients undergoing HD require special considerations during dental treatment because of the various conditions inherent to the disease, their multiple oral manifestations and the treatment side-effects.

Objective. Oral squamous cell carcinoma (OSCC) may be preceded by potentially malignant disorders such as leukoplakia and oral submucous fibrosis (OSF) and has a greater than normal risk of malignant transformation. Very little is known of cytokeratin (CK) alterations in OSF, leukoplakia, and OSCC. The aim of this study was to evaluate and compare the expression of CK8 and CK18 in normal oral mucosa, oral epithelial dysplasia, OSF, and OSCC by immunohistochemistry. Study Design. Paraffin-embedded normal (n = 10), dysplasia (n = 10), OSF (n = 10), and OSCC (n = 10) tissues were stained with CK8 and CK18 by immunohistochemistry. Results. Increased expression of CK8 and CK18 was seen in dysplasia, OSF, and OSCC. Staining pattern and intensity showed variations, with intensity of staining in basal and suprabasal layers for CK8 and CK18. Conclusions. Intensity of staining in the basal layer for CK18 was statistical significant, suggesting CK8 and CK18 as surrogate markers of malignant transformation. © 2012 Elsevier Inc. All rights reserved.

Background: Occupational injuries cause major health problems, which the developed, developing, and underdeveloped nations worldwide are facing today. The present study aimed to assess dental caries, periodontal health of stone mine workers, and the relationship between wasting diseases and the years of working experience.Methods: The study population comprised 510 men, selected based on the stratified cluster sampling procedure. Clinical oral examinations were carried out, and periodontal disease, dental caries, and wasting diseases were recorded.Results: Workers were in the age group of 17e56 years; the prevalence of dental caries in the workers was found to be 74%, with a mean decayed, missing, filled teeth index of 2.89. A periodontal pocket of more than 6 mm was observed in 6% of the workers.Conclusion: The oral health of mine workers is in a poor state; steps should be taken so as to provide basic medical and dental care facilities. ©2014, Occupational Safety and Health Research Institute.

Intramuscular hemangiomas are benign lesions uncommon in the head and neck region. The masseter is the most commonly involved muscle in the craniofacial region. In the pre-auricular region intramuscular hemangiomas are often clinically misdiagnosed as parotid swelling. In the absence of calcifications within the lumen of the lesion, advanced imaging investigations such as ultrasonography (US) and magnetic resonance imaging (MRI) are extremely useful in the diagnosis and treatment planning of such lesions. A case of intramuscular hemangioma occurring in an 8-year-old male patient is presented here. US, Color Doppler US, MRI and post contrast MRI were performed and diagnosis of intramuscular hemangioma in the masseter muscle of the left side was established. The lesion was treated with percutaneous sclerotherapy with no recurrence in a six-month follow-up. © 2015 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.

The history of complete denture impression procedures has been influenced largely by the development of impression materials from which new techniques and ideas arose. The purpose of this study was to compare the retention of complete dentures made by using different impression techniques like conventional, admixed, all green, and functional techniques. The results showed that there was significant difference in retention between the six techniques where functional technique showed the highest mean value of retention followed by elastomeric, all green, and admixed, while cocktail and green stick compound showed the lowest mean value. However, on clinical examination, the retention produced by the six techniques was satisfactory.

The present study was carried out to evaluate the usefulness of mini retromandibular approach on accessibility, scarring and stability in open reduction and internal fixation of sub condylar fractures.Fifteen patients underwent open reduction and rigid fixation of middle and low subcondylar fractures, with mini-retro mandibular approach.No signs of infection were observed in any patient postoperatively. Surgical scar was imperceptible and esthetically acceptable in all the cases. Out of 15 patients, only one patient had discrepancy in occlusion and after 2months satisfactory centric occlusion was achieved. Salivary fistula (parotid fistula) was observed in 3 cases within 1week postoperatively, which was treated spontaneously with the use of hypertonic saline. Transient facial nerve weakness was observed in 2 patients, in one patient it resolved in 4weeks postoperatively and in second patient 3months postoperatively. Mouth opening increased in all the patients with time. Average mouth opening at 1week interval was 19.6mm, at 2months interval 28.2mm, and after 6months 38.33mm suggesting that mouth opening gradually increased with time. At the end of 2months postoperatively none of the patients had any restriction in lateral movements. At 2months postoperatively 4 patients had deviation but none of the patients had any deviation 6months postoperatively.It is evident from the results of our study that open reduction and internal fixation using mini-retromandibular approach is good treatment option in management of mandibular condylar fractures.

Ameloblastic fibroma (AF) and related lesions comprise a complex group of mixed odontogenic tumors. Ameloblastic fibrodentinoma (AFD) is a rare tumor and is considered as a histological variant of AF showing inductive changes that lead to the formation of dentin. Although the most common site for this tumor is the posterior mandible, hereby we are reporting a case of AFD in the anterior maxillary region which is a very rare site for this group of tumors. The present case report highlights the clinical, radiological and histological presentation of AFD in order to raise awareness for the earlier diagnosis and precise management of this rare pathological entity.
