Knowledge, Attitude and practice survey on the perspective of oral lesions and dental health in geriatric patients residing in old age homes.

AIM: The aim of the study is to analyse the knowledge about oral lesions, the symptoms of such lesions and their attitude towards the treatment of these problems faced by institutionalised geriatric individuals. METHODS AND MATERIALS: This questionnaire-based survey was conducted among 103 institutionalised elders residing at various institutions. The questionnaire consisted of questions that addressed the medical and dental issues faced by the institutionalised elders and assessed their knowledge and attitude towards dental health. All the received responses were tabulated and the results were represented graphically. RESULTS: The results of the study showed that 44.66% of the elders underwent medical check-up once yearly and 72.82% of them visited the dentist. Of all 103 elders, none of them used dentures in spite of being edentulous and only 29.13% had any knowledge about oral lesions while the rest had no knowledge of the oral lesion and considered these lesions to be normal changes with increasing age. CONCLUSIONS: The findings of the present study demonstrate the need to improve access to oral healthcare and dental health education for the institutionalised elder population. In spite of the limitations of the study, we were able to record the obvious lack of dental hygiene practises, neglect and lack of motivation for proper dental care.

Evaluation of dermatoglyphic patterns using digital scanner technique in skeletal malocclusion: A descriptive study.

BACKGROUND: Skin is the largest human organ, which performs a dynamic role in life. The ectodermal layers of the skin found on the palm with intricate lines are stable throughout life and have grabbed scientific attention. Any disturbances during their formation might possibly have the likelihood of a person developing malocclusion. AIMS AND OBJECTIVES: The aims of this study were to evaluate and compare the dermatoglyphic pattern with various skeletal malocclusions. MATERIALS AND METHODS: The study was carried out on 40 outpatients reported with an age group of 18-20 years divided into four groups as follows: Group: I - 10 (Class I occlusion), Group: II - 10 (skeletal Class I malocclusion), Group: III - 10 (skeletal Class II malocclusion), and Group: IV - 10 (skeletal Class III malocclusion). The fingerprints were recorded using scanner exclusively designed for diagnostic purpose of the study. The collected data were analyzed using SPSS statistics software Version 23.0 to find which groups had significant differences. RESULTS AND CONCLUSION: Increased frequency of arch pattern was present in participants with Class I malocclusion, and loop patterns were observed in those with Class I occlusion and Class III malocclusion and whorl patterns in Class II malocclusion with P < 0.05. Dermatoglyphic pattern remains constant throughout life and it can be used as a noninvasive aid in determining the development of malocclusion at a very early age.

p53 & Cyclin D1 expression in surgically resected clear margins of oral squamous cell carcinoma

Oral squamous cell carcinoma (OSCC) is one of the most well-known malignancies that affect the human population worldwide. The early diagnosis and early intervention of OSCC help improve the survival rate of the patients. The tumour free surgical margins are a positive prognostic factor for recurrence-free survival. The molecular markers can be used to detect the tumour free surgical margins. Aim: The aim of the study is to evaluate the expression of p53 & Cyclin D1 marker in resected surgical apparently clear margins and to correlate the p53 & Cyclin D1 expression with clinicopathological characteristics and patient outcome. Methods: The study population included retrospective cases of OSCC with apparently clear margins (2017-18) n=10 and Clinicopathological variables relevant to survival analysis were recorded. Finally, two margins were selected from each case, a total of 20 margins were included in this study. Paraffin-embedded wax blocks retrieved and tissue sections were made. Expression of cyclin D1 and p 53 was assessed by the immunohistochemical staining procedure Results: Positive expressions Cyclin D1 in 40% of mild dysplasia margins and 60% in clearance adequate margins were present. p53 expression was seen in 16% of mild dysplasia margins and 84% in clearance adequate margins. The expression of p53 and Cyclin D1 molecular markers are noted in the basal & parabasal layer of epithelium. Conclusion: Molecular markers could play a more reliable method for the assessment of dysplasia at the margins

Evaluation of muscle involvement & degeneration in advanced oral submucous fibrosis using three different stains ­ a retrospective cross-sectional study / Avaliação do envolvimento e degeneração muscular na fibrose submucosa oral avançada usando três colorações diferentes - um estudo transversal retrospectivo

Background: Oral submucous fibrosis (OSMF) is graded according to various histological factors which include the epithelial changes and the connective tissue changes. These features could be identified in routine Hematoxylin and Eosin (H and E) staining in shades of pink. However, the use of special stains provides a contrast to various connective tissue components thereby aiding in better visualization of these connective tissue changes in advanced OSMF cases. Objective:To compare and evaluate muscle involvement and degeneration in advanced oral submucous fibrosis using three different stains namely, H&E, Van Gieson, and Masson's Trichrome. Material and Methods: 10 Formalin-fixed paraffin-embedded tissue sections of advanced OSMFwere stained using 3 different stains namely Hematoxylin and Eosin (H&E), Van-Gieson, and Masson trichrome. The results obtained were tabulated and statistically analyzed using Kruskal Wallis ANOVA. Results: The hyalinization and fibrosis involving the skeletal muscle were better visualized in Masson's Trichrome but were not statistically significant. The muscle degeneration in deeper areas was better visualized in Masson's trichrome when compared to the H&E and Van Gieson. Conclusion: Hematoxylin and eosin stains all the connective tissue components in various shades of pink, use of special stains bestows contrast between different components of connective tissue, thus improvising grading of OSMF. Masson's trichrome stain can be used as a single adjunct to hematoxylin and eosin stain as changes in the superficial and deeper connective tissue could be ascertained (AU)

Contexto: A fibrose submucosa oral (FSO) é classificada de acordo com vários fatores histológicos que incluem alterações epiteliais e do tecido conjuntivo. Essas características podem ser identificadas na coloração de rotina com Hematoxilina e Eosina (H&E) em tons de rosa. No entanto, o uso de colorações especiais fornece um contraste para vários componentes do tecido conjuntivo, auxiliando assim na melhor visualização dessas alterações do tecido conjuntivo em casos avançados de FSO. Objetivo: Comparar e avaliar o envolvimento e degeneração muscular da fibrose submucosa oral avançada usando três colorações diferentes: H&E, Van Gieson e Tricrômio de Masson. Material e Métodos: 10 seções de tecido fixadas em formalina e embebidas em parafina de FSO avançada foram coradas usando essas três colorações. Os resultados obtidos foram tabulados e analisados estatisticamente por meio do teste de Kruskal Wallis. Resultados: A hialinização e fibrose envolvendo o músculo esquelético foram melhor visualizadas no tricromo de Masson, mas não foram estatisticamente significativas. A degeneração muscular em áreas mais profundas foi melhor visualizada no tricrômico de Masson, quando comparado ao H&E e Van Gieson. Conclusão: Hematoxilina e Eosina coloram todos os componentes do tecido conjuntivo em vários tons de rosa. O uso de colorações especiais confere contraste entre os diferentes componentes do tecido conjuntivo, melhorando assim a avaliação da FSO. A coloração com tricrômio de Masson pode ser usada como um único adjunto para a coloração de Hematoxilina e Eosina, pois assim é possível verificar alterações superficiais e profundas no tecido conjuntivo.

Metastasizing Ameloblastoma - a perennial pathological enigma? Report of a case and review of literature.

The Ameloblastoma is a slow growing locally invasive odontogenic epithelial neoplasm with a high recurrence rate and a low tendency to metastasize. Metastasis in Ameloblastoma was first described by Simmons and Emura in the 1920s. Slootweg and Muller proposed the term Malignant Ameloblastoma to describe a well-differentiated ameloblastoma that metastasizes but maintains the characteristic cytologic features of the original tumour and the term Ameloblastic Carcinoma to an ameloblastoma with malignant cytological features. About 2% of ameloblastomas undergo metastasis. So far there have only been two cases of Metastasizing Ameloblastoma reported from the Indian Subcontinent. We present the case of a 22-year-old male Indian patient, who presented with a diffuse swelling in the left posterior mandible. Radiographs revealed a multilocular radiolucency in the left mandible. On histopathological examination, the lesion was diagnosed as follicular ameloblastoma. Four years later the patient presented with a swelling in the left submandibular region. Histological examination revealed metastatic ameloblastoma within the cervical lymph node.
