What does non-carious mean?

Non-carious cervical lesions (NCCLs) are a group of lesions that are characterised by a loss of hard dental tissue at the cementoenamel junction (CEJ) region at the neck of the tooth, without the action of microorganisms or inflammatory processes.

What is a non-carious lesion?

15. 1:41. Non-carious Cervical Lesions describes a condition where tooth structure is lost below the gumline due to forces other than decay. Symptoms of Non-carious cervical lesions are often visual, with notches appearing on the teeth where the crown and root of the tooth meet.

What is non-carious tooth loss?

Non-carious tooth surface loss is a normal. physiological process occurring throughout life, but it can often become a problem affecting function, aesthetics or cause pain. This loss of tooth structure or wear is often commonly termed abrasion, attrition, erosion and abfraction.

Why you will need to restore non-carious lesions?

At this time, restoration of noncarious cervical lesions (NCCLs) is a common occurrence in clinics nowadays. Some reasons for this are the growth of the elderly population, a smaller rate of tooth loss, and possibly the increase of some etiologic factors.

What does it mean when a tooth has a carious lesion?

Carious lesions where there is a visible macroscopic breakdown in the tooth surface (that is, a visible 'hole') and the area may have softened walls or floor. Dental caries (dental decay, tooth decay or 'cavities')

Non Carious Tooth Wear//Attrition, Abrasion, Abfraction, Erosion//Clinical Appearance, Diagnosis

Is a carious lesion a cavity?

Cavitated Caries Lesions

Cavitated lesions (also referred to as cavities) are lesions that have progressed to a more advanced stage.

Is the carious lesion most commonly found in elderly patients?

Myth #1. The first myth is that children are at the greatest risk of tooth decay. Dental caries is the most common chronic disease of childhood,^2,3 but older adults are at greater risk than children. Caries remains the most prevalent disease among older adults—affecting 93% of those age 65 or older.

How do you treat non carious cervical lesions?

Treatment options include techniques to alleviate dentin hypersensitivity and the placement of an adhesive restoration, eventually in combination with a root coverage surgical procedure. An adhesive restoration is considered the last treatment option for NCCLs.

What is the most likely cause of sensitivity related to a non carious cervical lesion?

Current research indicates two primary causes of these lesions- the first is abrasion, where the tooth material is reduced due to overly aggressive or improper tooth brushing technique. The other possible cause is abfraction – which creates the notches by placing stress on the teeth through grinding and clenching.

What is a lesion on the cervix?

In cervical dysplasia, abnormal cells develop on the surface of the cervix. These abnormal cells are called lesions.

How do you treat surface loss of teeth?

The conditions leading to tooth surface loss are common (if observed). Treatment can be as basic as a night guard, or it may involve opening the bite and placing veneers or crowns.

What does abfraction mean?

An abfraction is a condition in which small notches, or lesions, develop near the gum line. These notches are often angular, however, they may become rounded over time as a result of abrasively brushing the teeth.

What are the causes of loss of tooth substance?

Tooth surface loss (TSL) or tooth wear (TW) is an irreversible loss of hard tooth structure caused by factors other than those responsible for dental caries. TSL is observed clinically as attrition, abrasion, abfraction, and erosion.

When should Abfractions be restored?

Here, we suggest that restorative treatment of abfraction lesions should be considered only when one or more of the following conditions are present: 1) active, cavitated carious lesions associated with abfraction lesions; caries risk assessment must be conducted to determine the most appropriate caries management plan ...

When should I restore NCCL?

RESTORATIVE CARE

If the lesions are esthetically displeasing, become detrimental to pulp health, or if the patient experiences dentinal hypersensitivity, NCCLs should be restored.

What causes cervical caries?

Lactic acid, which appears during the life of pathogenic bacteria, destroys the thin enamel of the tooth in the area of its contact with the gums and becomes the main cause of caries. Brushing your teeth with abrasive toothpaste can also cause cervical decay.

Where do Class V lesions occur?

Class V lesions are those occurring at the cervical aspect of the buccal or lingual surfaces of teeth. Conventionally, based on the etiology, a class V lesion is broadly classified as Carious and Non-Carious lesions. The non-carious cervical lesions are further categorized into abrasion, erosion and abfraction .

What causes class5 caries?

Combined with gingival recession and exposed root surfaces, with xerostomia, teeth are at a greater risk of Class V carious lesions. Currently more than 400 medications can cause dry mouth. These medications include antihypertensives, antidepressants, analgesics, tranquilizers, diuretics, and antihistamines.

What is a Class 5 filling?

Class V: Cavity on the cervical third of the facial or lingual surfaces of any tooth (Think of the neck of the tooth)

How does dentin hypersensitivity occur?

Dentin hypersensitivity has been defined as the pain arising from exposed dentin, typically in response to chemical, thermal, tactile or osmotic stimuli that cannot be explained as arising from any other form of dental defect or pathology [13].

Does GIC bond to enamel?

As a restorative material, GIC bond to the enamel and dentin via ionic and polar bonds, and the intimate molecular contact facilitates ion exchange of fluoride with the hydroxyl ions in the apatite of the surrounding enamel^5,39.

What is considered high caries risk?

Characteristics that place a patient at high caries risk include: Sugary Foods or Drinks: Bottle or sippy cup with anything other than water at bedtime (ages 0 to 6 years) or frequent or prolonged between meal exposures/day (ages >6 years)

What does high caries risk mean?

Two significant factors that indicate a patient is at high-risk include caries in the last three years and past restorative care, thereby indicating a higher bacterial count. A current caries assessment should be performed at future dental appointments.

What is low caries risk?

A patient at moderate risk of caries generally displays no disease indicators, but more risk factors than protective factors. A patient at low caries risk displays more protective factors than risk factors. To remain caries free or inhibit caries progression, protective factors must outweigh risk factors.

How do you treat carious lesions?

Dentine/cavitated carious lesions can be treated by complete removal of decayed parts of the tooth and placement of a filling. Dentists call this non‐selective carious tissue removal and conventional restoration (CR).
