ProsthodonticsEpulis fissuratum is a chronic hyperplastic tissue reaction that occurs due to chronic irritation from an ill-fitting or overextended denture flange. The overextension of the labial flanges causes trauma to the soft tissues, leading to the formation of folds of fibrous tissue in the vestibule.

Physiology
The sympathetic nervous system primarily uses norepinephrine (also known as noradrenaline) as its neurotransmitter. It is released from the synaptic terminals of postganglionic sympathetic fibers and acts on adrenergic receptors, which are found on various target cells throughout the body. This neurotransmitter is essential for the body's "fight or flight" response, contributing to increased heart rate, dilated pupils, and other physiological changes associated with stress or emergency situations.

PhysiologyThe normal plasma concentration of glucose that does not lead to its excretion in the urine is approximately 100 mg/100 ml, below which glucose is typically reabsorbed completely.

Sodium chloride is an accelerator up to about 2% of the hemihydrates, but at a higher concentration, it acts as a retarder. Sodium sulphate has its maximum acceleration effect at approximately 3.4%; at greater concentrations, it becomes a retarder. Citrates. acetates and borates generally retard the reaction.
The most commonly used accelerator is potassium sulphate. It is particularly effective in concentrations higher than 2% since the reaction product. which seems to be syngenite (K,Ca[SO4].H1O) crystallizes rapidly. Many soluble sulphates act as accelerators, whereas powdered gypsum (calcium sulphate dehydrate) accelerates the setting rate, because the
particles act as nuclei of crystallization.

ProsthodonticsBefore altering the abutment contour for clasp retention, it is essential to establish the guiding planes. This is done by disking the proximal surfaces of the abutment teeth to create a flat, smooth surface that will guide the RPD during insertion and removal. Once the guiding planes are in place, the contour of the abutment can be altered to accommodate the placement of the retentive elements such as rests and minor connectors.
