Cleidocranial dysplasia (CCD) is a genetic disorder caused by a mutation in the RUNX2 gene, not an alpha one gene. The condition is characterized by a range of symptoms, including large fontanelles and open sutures in the skull, large frontal sinuses, and dental abnormalities such as a high arch palate and prolonged retention of deciduous teeth.

Chelation of carboxyl groups of the polyacids with the calcium in the apatite of enamel and dentin is the main mechanism through which glass ionomer bonds to tooth structure. Glass ionomers release fluoride which results in the inhibiton of the progression of secondary caries. GIC is relatively biocompatable.
They elicit a greater pulp reaction as compared to ZnoE but generally less compared to zinc phosphate cement.

Oral PathologyWarthin's tumour (also known as papillary cystadenoma lymphomatosum) is a benign tumour that occurs almost exclusively in the parotid gland, which is a major salivary gland. It rarely, if ever, occurs in the minor salivary glands.

In orthodontics, wires with a low load deflection rate are typically preferred for areas requiring large tooth movements because they provide a more constant force as the tooth moves and the appliance is deactivated. This constant force is beneficial for controlling the rate of tooth movement.

Physiology
The parasympathetic nervous system acts on muscarinic receptors (specifically M2 receptors) in the heart to decrease the heart rate and atrial contractility, thereby contributing to a resting state and energy conservation.

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.

ProsthodonticsThe high survey line is characterized by being positioned in the occlusal third of the tooth in both the near and far zones, which is important for determining the contour of the tooth.

Calcium hydroxide is used in cases of rampant caries and unhygienic oral conditions due to its antibacterial and tissue-dissolving properties.
