The Dental Pulp Cap and Pulpotomy: Healing Procedures or Just Plain Magic?
Abstract: Mesenchymal stem cells in the dental pulp are multi-potent progenitors with the ability to differentiate into many different cell types including odontoblasts that function in the formation of reparative (secondary) dentin. However, reparative dentin is a two-edged sword to the pulp; it is necessary to ‘wall-off’ a pulp exposure or pulpotomy, but at the same time, it compresses the pulp in its finite living space causing inflammatory and necrotic changes. …

Unani Concept of Tadarrun-e-Revi (Pulmonary Tuberculosis): A Review
Abstract: In Unani system of medicine, pulmonary tuberculosis is known as Tadarrun-e-Revi. Unani physicians also called it Diq or humma-e-diq or tap-e-diq. The ulcer which is formed in lungs due to tuberculosis is called sil. The word Diq means thinness or debility. In Diq, the increased temperature of body destroys the body fluid, because of which, the body of affected person becomes thin and dry. Hence the disease is called Humma-e-diq. …
