Study Notes

Molecular techniques Different molecular techniques such as fluorescent in situ hybridization, Southern blot, etc... can be used to detect genetic diseases.

Pit and Fissure Sealants Pit and fissure sealants are preventive dental materials used to protect occlusal surfaces of teeth from caries by sealing the grooves and pits that are difficult to clean. According to Mitchell and Gordon (1990), sealants can be classified based on several criteria, including polymerization methods, resin systems, filler content, and color. Classification of Pit and Fissure Sealants 1. Polymerization Methods Sealants can be d…

Trace Elements Type Elements Cariogenic Selenium, Lead, Barium Protective Molybdenum, Vanadium Vitamin K Exhibits anti-cariogenic properties by inhibiting bacterial growth. Veillonella Considered anti-cariogenic due to lack of glycolytic enzymes; utilizes lactate produced by other bacteria.…

MANDIBULAR CENTRAL INCISORS These are the first permanent teeth to erupt, replacing deciduous teeth, and are the smallest teeth in either arch Facial Surfaces:-The facial surface of the mandibular central incisor is widest at the incisal edge. Both the mesial and the distal surfaces join the incisal surface at almost a 90° angle. Although these two surfaces are nearly parallel at the incisal edge, they converge toward the cervical margin. The developmenta…

Chromium Alloys for Partial Dentures Applications - Casting partial denture metal frameworks Classification a. Cobalt-chromium b. Nickel-chromium c. Cobalt-chromium-nickel Composition a. Chromium-produces a passivating oxide film for corrosion resistance b. Cobalt-increase~ the rigidity of the alloy c. Nickel-increases the ductility of the alloy d. Other elements-increase strength and castability Manipulation a. Requires higher temperature …
