Central Giant Cell Granuloma ; A Case Report.

Central giant cell granuloma ( CGCG) was classified as rarely aggressive idiopathic benign intraosseous lesion that occurs mostly exclusively in the jaws. It occurs most frequently in young women. It is usually slow growing and non neoplastic lesion which exhibits a spectrum of clinical behavior ranging from non aggressive to aggressive variants. The striking feature of this case is its aggressive nature and presence of this lesion in the anterior part of maxilla which considers being a rare finding as the lesion commonly occurs in the mandibular region anterior to first molar.

Compound Odontoma Associated With An Unerupted Maxillary Central Incisor.

Odontoma is a hamartoma of odontogenic origin which contains both epithelial and mesenchymal cells exhibiting complete differentiation with enamel and dentine laid down in abnormal position. It may result from the extraneous buds of odontogenic epithelial cells from the laminadura, enamel, dentin or cementum. The etiology of odontoma is unknown it may due to trauma, infection or genetic transmission. Treatment includes simple excision with no recurrence noted. The aim of this paper is to present a thorough review on the etiology, clinical presentation, histopathological features and treatment aspects of odontomas.

"Comparative Evaluation of Microleakage of Composite Restorative Materials".

To evaluate and compare the marginal leakage in class V cavities restored with three different tooth colored restorative materials using dye penetration system. Materials and methods: Thirty extracted premolars were randomly selected for this study. Standardized classV cavities were prepared and then divided into three equal groups. Group I was restored with nano filled composite, Group II was restored with hybrid composite and group III with polyacid modified composite. They were then subjected to thermo cycling, immersed in 2% methylene blue dye, sectioned and examined under stereomicroscope. Dye penetration for each section was recorded and data was analyzed. Results: Lowest micrileakage was recorded in group I and highest leakage recorded in Group III.Conclusion: Nanofilled composite resins provide a better sealing than hybrid and polyacid modified composites.
