Molecular biology of wound healing.

Wound healing is a dynamic process that involves the integrated action of a number of cell types, the extra cellular matrix, and soluble mediators termed cytokines. In recent years considerable advances have been made in the research, knowledge, and understanding of growth factors. Growth factors are, in essence, proteins that communicate activities to cells.

Clinical management of highly resorbed mandibular ridge without fibrous tissue.

Alveolar ridge atrophy poses a clinical challenge toward the fabrication of successful prosthesis. Resorption of mandibular denture bearing areas results in unstable non-retentive dentures associated with pain and discomfort. This article describes rehabilitation procedure of a patient with resorbed ridge with maximal areas of coverage to improve support and neutral zone arrangement of teeth to improve stability of denture.

The role of diagnostic ultrasound as a new diagnostic aid in oral and maxillofacial surgery.

Only very few studies have been done in the past to evaluate the usefulness and limitations of ultrasonography in oral and maxillofacial surgery. This study, though in an embryonic stage, has been done to bring this technique to limelight and to put forth the importance of its use and limitations in the branch of oral surgery. The purpose of this study was to investigate and study the characteristic pattern of the oral tissues on gray scale ultrasonography and to assess the practical applicability of this new diagnostic technique in diagnosing various tissue pathologies in the field of oral and maxillofacial surgery.
