Amalgam filling: giving overall darker appearance to the tooth. Amalgam fillings often stain the tooth they are placed in. [11] This is most noticeable in very old fillings, as pigment slowly leaches out of the amalgam filling material and its associated corroded surfaces. In addition, metallic fillings cast a shadow that can be visible through ...
Diagramatic representation of mucosal erosion (left), excoriation (center), and ulceration (right) Simplistic representation of the life cycle of mouth ulcers. An ulcer (/ ˈ ʌ l s ər /; from Latin ulcus, "ulcer, sore") [2] is a break in the skin or mucous membrane with loss of surface tissue and the disintegration and necrosis of epithelial tissue. [3]
Tooth whitening or tooth bleaching is the process of lightening the colour of human teeth. [1] Whitening is often desirable when teeth become yellowed over time for a number of reasons, and can be achieved by changing the intrinsic or extrinsic colour of the tooth enamel . [ 2 ]
In dental enamel, fluorosis causes subsurface porosity or hypomineralizations, which extend toward the dentinal-enamel junction as the condition progresses and the affected teeth become more susceptible to staining. Due to diffusion of exogenous ions (e.g., iron and copper), stains develop into the increasingly and abnormally porous enamel. [7]
Remineralization is a natural process and does not have to involve fluoride. Tooth remineralization is the natural repair process for non-cavitated tooth lesions, [1] [2] in which calcium, phosphate and sometimes fluoride ions are deposited into crystal voids in demineralised enamel. Remineralization can contribute towards restoring strength ...
Acid erosion is a type of tooth wear.It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin. [1] Dental erosion is the most common chronic condition of children ages 5–17, [2] although it is only relatively recently that it has been recognised as a dental health problem. [3]
The individual ulcers (aphthae) recur periodically and heal completely, although in the more severe forms, new ulcers may appear in other parts of the mouth before the old ones have finished healing. Aphthous stomatitis is one of the most common diseases of the oral mucosa , and is thought to affect about 20% of the general population to some ...
