Pin size   In general, increase in diameter of pin offers more retention but large sized pins can result in more stresses in dentin. Pins are available in four color coded sizes:           Name Pin diameter Color code ·         Minuta 0.38 mm Pink ·    &nbs…

Radiographic Advancements in Caries Detection Advancements in dental technology have significantly improved the detection and quantification of dental caries. This lecture will cover several key technologies used in caries detection, including Diagnodent, infrared and red fluorescence, DIFOTI, and QLF, as well as the film speeds used in radiographic imaging. 1. Diagnodent Technology: Utilizes infrared laser fluorescence for the detection and…

Tooth eruption Theories Tooth eruption occurs when the teeth enter the mouth and become visible. Although researchers agree that tooth eruption is a complex process, there is little agreement on the identity of the mechanism that controls eruption. Some commonly held theories that have been disproven over time include: (1) the tooth is pushed upward into the mouth by the growth of the tooth's root, (2) the tooth is pushed upward by the growth of the bone arou…

Rheumatic fever Before antibiotic therapy, this was the most common cause of valvular disease. 1. Usually preceded by a group A streptococci respiratory infection; for example, strep throat. 2. All three layers of the heart may be affected. The pathologic findings include Aschoff bodies, which are areas of focal necrosis surrounded by a dense inflammatory infiltration. 3. Most commonly affects the mitral valve, resulting in mitral valve stenosis, regurgitati…
