Non-Carious Lesions Management Quiz

Tooth Wear

• Tooth wear is described as the loss of dental hard tissues from the surfaces of the teeth caused by factors other than dental caries, trauma, and developmental disorders.
• Physiological wear is considered an age-related normal process.

Hard Tooth Tissue Defects

• Abfraction is not a hard tooth tissue defect mentioned in the text.

Challenges in Dentistry

• Tooth wear presents one of the greatest challenges in dentistry.

Tooth Lesions

• Abrasion lesions are not associated with the presence of microorganisms that cause defects in tooth structures.

Treatment Planning

• The term "programmed treatment planning" describes the treatment planning process for severe wear if the rules are precisely adhered to in correct sequence.

Attrition

• Attrition is the mechanical wear of tooth structure due to tooth-to-tooth contact without any foreign substance intervention.
• Attrition may be regarded as pathological if the rate of wear is greater than expected or atypical for the patient's age.
• Pathological causal factors for attrition include bruxism and parafunctional habits.
• The clinical appearance associated with attrition is a flat or shiny wear facet.

Vertical Dimension Loss

• The term "vertical dimension loss" is used to describe tooth wear associated with the loss of vertical dimensions of teeth.

Tooth Wear Types

• Abrasion is a type of tooth wear that involves the wear of tooth structure due to mechanical factors other than mastication.
• Erosion is a type of tooth wear characterized by the loss of tooth structure due to chemical processes without bacterial involvement.
• Attrition is a type of tooth wear that involves the mechanical wear of tooth structure due to tooth-to-tooth contact.
• Abfraction is a type of tooth wear associated with the loss of tooth structure due to flexure and fatigue caused by occlusal forces.

Abrasion

• The term "abrasion" is used to describe the loss of tooth structure by mechanical forces during tooth brushing or other abrasive actions.

Tooth Movement

• The term " migrations" is used to describe the flattening of proximal surfaces and widening of proximal contact areas due to physiologic tooth movement.
