Esthetic Rehabilitation of Anterior Dentition with Different Types of Ceramic Restorations: Two Case Reports.

All-ceramic systems represent an excellent restorative alternative for fixed dental prostheses, single crowns, and veneers in the anterior dentition. With respect to improved mechanical properties, lithium disilicate ceramic material provide a broad range of indications, and extended veneers can serve as an alternative to full crowns. Although ceramic veneers represent a more conservative approach compared to crowns, the correct indication is essential to achieving the ideal outcome.

Differences in CD44s expression in HNSCC tumours of different areas within the oral cavity.

Background And Aims: There is evidence of differences in p63 expression in HNSCC (head and neck squamous cell carcinoma) tumours of different sub-sites within the oral cavity which appear to have an important role in CD44 regulation. The aim of this study was to investigate CD44 expression in HNSCC tumours in different areas of the oral cavity.

Methods: Formalin-fixed and paraffin-embedded oral squamous cell carcinoma specimens from 29 patients were investigated.
