Dental Materials
The hybrid layer formed by the infiltration of resin into the etched dentin provides a strong mechanical interlock and acts as a barrier to prevent microleakage between the restoration and the tooth structure.

EndodonticsFormocresol is a commonly used fixative and disinfectant in endodontic treatment. It is known to produce tissue fixation by causing coagulative necrosis. This is the process by which the proteins within the tissue are coagulated or precipitated, leading to the death of cells due to dehydration and denaturation. The necrotic tissue is then replaced by a fibrous connective tissue, which is essential for the healing process in the periapical region following root canal treatment.

EndodonticsLaser Doppler flowmetry is used in dentistry to assess pulp vitality by measuring blood flow within the pulp tissue. It detects the movement of red blood cells using a low-power laser beam, making it a non-invasive method for determining the health of a tooth's pulp.

EndodonticsNight guard bleaching refers to a dentist-prescribed home-applied technique where the patient uses custom-fitted trays filled with carbamide peroxide gel, typically worn overnight. Key features: 1) Dentist provides custom trays and bleaching gel, 2) Patient applies treatment at home under professional supervision, 3) Uses lower concentrations (10-15% carbamide peroxide) for safety, 4) Extended contact time (6-8 hours) compensates for lower concentration, 5) Also called tray bleaching or home bleaching.

Hemoglobinuria is a sign of acute intravascular hemolysis (occurring within minutes/hours). Delayed reactions usually involve extravascular hemolysis where RBCs are destroyed in the spleen, resulting in spherocytosis and drop in Hb, but not free hemoglobin in urine.

Guiding planes are parallel vertical surfaces on abutment teeth or other intraoral structures that direct the path of insertion and removal of a removable partial denture. Their primary function is to provide a predictable and consistent path, which helps achieve predictable clasp retention and stability.
