	'''Abfraction''' is a theoretical concept in dentistry that describes the loss of tooth structure, particularly at the cervical areas of teeth, due to ~~biomechanical loading~~ forces. ~~These~~ forces cause flexure and ~~ultimately lead to~~ the ~~breaking away of hard tissue. Abfraction is considered one~~ of the ~~[[non-carious cervical lesions]] (NCCLs)~~, ~~which also include~~ [[~~abrasion (dental)\|abrasion~~]] and [[~~erosion (dental)\|erosion~~]].		'''Abfraction''' is a theoretical concept in dentistry that describes the loss of tooth structure, particularly at the cervical areas of teeth, due to mechanical forces. This phenomenon is believed to occur as a result of [[occlusal]] forces that cause flexure and stress concentration at the cervical regions of the teeth, leading to [[enamel]] and [[dentin]] loss.

	==Mechanism==		==Mechanism==
	Abfraction is ~~believed~~ to occur when occlusal forces, such as those from [[~~bruxism~~]] or [[~~malocclusion~~]], create stress concentrations at the cervical areas of teeth. These ~~stresses lead~~ to microfractures in the enamel and dentin, ~~eventually resulting~~ in the loss of tooth structure~~. The lesions are typically~~ wedge-shaped ~~and occur at the gum line~~.		Abfraction is thought to occur when occlusal forces, such as those from [[chewing]] or [[bruxism]], create stress concentrations at the cervical areas of the teeth. These forces cause the tooth to flex, leading to microfractures in the enamel and dentin. Over time, these microfractures can result in the loss of tooth structure, forming characteristic wedge-shaped defects.

	==Clinical Presentation==		==Clinical Presentation==
	Abfraction lesions ~~are characterized by their distinct shape and location. They are usually:~~		Abfraction lesions typically appear as wedge-shaped notches at the cervical areas of the teeth, near the [[gingival margin]]. These lesions are often found on the [[buccal]] or [[facial]] surfaces of the teeth and can vary in depth and width. They may be accompanied by [[tooth sensitivity]] due to the exposure of dentin.
	* Wedge-shaped
	* Located at the cervical ~~area~~ of the ~~tooth~~, near the ~~gum line~~
	* Found on the buccal or facial surfaces of teeth

	~~These~~ lesions ~~can be sensitive to thermal stimuli and may lead~~ to [[~~dentin hypersensitivity~~]].		==Differential Diagnosis==
			Abfraction should be differentiated from other types of non-carious cervical lesions, such as:
			* [[Abrasion (dental)\|Abrasion]]: Loss of tooth structure due to mechanical wear, often from aggressive tooth brushing.
			* [[Erosion (dental)\|Erosion]]: Loss of tooth structure due to chemical processes, such as exposure to acidic substances.

	==~~Diagnosis~~==		==Management==
	Diagnosing abfraction involves a thorough clinical examination and consideration of the patient's dental history. Dentists look for the characteristic shape and location of the lesions and assess the patient's occlusion and habits such as bruxism. Differential diagnosis is important to distinguish abfraction from other NCCLs like abrasion and erosion.		The management of abfraction lesions involves addressing the underlying occlusal forces and restoring the lost tooth structure. Treatment options may include:
			* Occlusal adjustment to reduce excessive forces on the affected teeth.

	~~Treatment~~ of abfraction lesions ~~focuses on managing~~ the underlying ~~causes~~ and restoring the lost tooth structure. ~~Approaches~~ may include:		* Restorative procedures, such as [[composite resin]] fillings, to restore the lost tooth structure and protect the dentin.

	* Use of [[night guard]]s to prevent bruxism
	* Restorative procedures, such as composite resin fillings, to restore the tooth~~'s shape~~ and ~~function~~

These forces cause flexure and ultimately lead to the breaking away of hard tissue.
