Dental Hypotheses Apr-Jun 2014. Vol 5 ( 2) 2014;59-65 Objectives: The study aims to establish an etiological association between diabetes and precancerous lesions of the oral cavity by cytomorphometric analysis of the oral epithelium. Study Design: Smears were obtained from three distinct oral sites – buccal mucosa, dorsum of the tongue and the floor of the mouth in ten controls and ten patients previously diagnosed with type II diabetes. The oral smears were stained with Papanicolaou SA-36 solution. An eye – piece graticule was used to obtain the cytoplasm and nuclear dimension; where larger dimension was denoted as “D” and the smaller dimension was denoted as “d”. The nuclear area (NA), nuclear diameter (ND), cytoplasmic area (CA) and the cytoplasmic / nuclear ratio (C/N) were evaluated from 50 cells predominant in each oral site. Statistical Analysis: The cytomorphometric data obtained was compared between the group of diabetic patients and the control groups using the student’s t- test (SPSS version 11.0). Results: Results showed that the nuclear area and the nuclear diameter of oral epithelial cells were increased in diabetic patients, as compared to non- diabetics, while the non- diabetic patients demonstrated an increase in nuclear ratio. Conclusions: The results from this study suggest that diabetes mellitus can cause alterations in oral epithelial cells that are detectable with exfoliative cytology. Key words: Cytomorphometry, diabetes mellitus, oral exfoliative cytology`

Journal of Clinical and Diagnostic Research. 2014 Jun, Vol-8(6):42-45 Introduction: Fibro-osseous lesions, along with few reactive lesions of the jaws exhibit an overlapping histo- morphologic spectrum with respect to the nature of calcifications and stromal components. This causes difficulty in assessing the origin, pathogenesis and diagnosis of these lesions. Aim: The present study analyses the mineralized components, cellularity, stromal density and stromal composition (nature of collagen, presence of elastic and oxytalan fibres) in cases of ossifying fibroma (OF), fibrous dysplasia (FD) Materials and Methods: The study included a histochemical evaluation of six cases each of FD, OF and POF. Five consecutive sections of each case were stained with hematoxylin and eosin, picrosirius red (to assess maturation of fibres in polarizing light), van Gieson (for area fraction and collagen density) and aldehyde fuchsin (for elastic and Results: Significantly higher amounts of mature bone were seen in FD while cementicles having microlamellar pattern were predominant in OF and POF (p < 0.001). Area fraction, collagen density and immature stromal fibre content was higher in POF followed by FD and OF (p= 0.039). Oxytalan and elastic fibres were absent in FD. Conclusion: Higher cellularity of the stroma in OF was indicative of its neoplastic behaviour. Higher composition of oxytalan and elastic fibres in OF and POF supports their periodontal ligament origin. FD was distinct with more mature fibres in a lamellated bone and absence of oxytalan fibres
