HEALING Definition. Replacement of damages tissue by healthy tissue. It is an attempt to restore the tissue to structural and functional normalcy. Healing may be of 2 types A. Regeneration. B. Repair by granulation tissue. A. Regeneration   Where the replacement is by proliferation of parenchymatous cells of type destroyed. This depends upon: (1) Regenerative capacity of cells. Cells may be : (a) Labile cells which are constantly prol…

Classification Epitheliums can be classified on appearance or on function Classification based on appearance - Simple - one layer of cells - Pseudostratified - looks like more than one layer but is not - Stratified - more than one layer of cells Simple epitheliums Simple squamous epithelium  Cells are flat with bulging or flat nuclei.  Lines the insides of lung alveoli and certain ducts in the kidney  Forms serous membranes …

Gingival Crevicular Fluid (GCF) is a serum-like exudate found in the gingival sulcus. Initially considered a transudate in healthy gingiva, it transitions to an inflammatory exudate during disease states. GCF serves as a valuable diagnostic medium due to its dynamic composition, reflective of periodontal status. Composition of GCF GCF contains a variety of biochemical and cellular components that mirror periodontal health: Compo…

Applegate's Classification is a system used to categorize edentulous (toothless) arches in preparation for denture construction. The classification is based on the amount and quality of the remaining alveolar ridge, the relationship of the ridge to the residual ridges, and the presence of undercuts. The system is primarily used in the context of complete denture prosthodontics to determine the best approach for achieving retention, stability, and suppo…

These amino acids have aromatic side chains, which contribute to protein structure, UV absorbance, and biochemical signaling. 1. Phenylalanine (Phe, F) Structure: Contains a benzyl side chain (a phenyl group attached to a CH₂). Properties: Non-polar, hydrophobic. Function: Precursor to tyrosine, dopamine, norepinephrine, and epinephrine. 2. Tyrosine (Tyr, Y) Structure: Similar to phenylalanine but with a hydroxyl …
