Why do we 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.

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.

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 ...

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 does non-carious mean?

15. 1:41. Non-carious Cervical Lesions describes a condition where tooth structure is lost below the gumline due to forces other than decay.

How to Restore Non-Carious Lesions on Several Mandibular Teeth

What is non-carious tooth surface 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.

What is 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')

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 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.

Should abfractions be filled?

Abfractions, however, can cause a healthy tooth to lose some of its strength and, in rare cases, may cause a tooth to break. In those situations, it may be wise to reinforce the tooth with a filling compound. This can be done easily, and often does not require any drilling.

Does abfraction need to be treated?

While it doesn't necessarily require treatment, abfraction can lead to serious problems with your teeth and gums. If you think you might have abfraction, it's important to have your dentist make the diagnosis and monitor your oral health.

How are abfraction lesions treated?

To treat a dental abfraction, the lesion is filled, much like a cavity. Your dentist will apply composite resin material to the affected area before shaping it and curing it with a special dental light. Finally, the tooth will be smoothed and polished to a natural-looking shine.

What is a Class V restoration?

These are commonly known as Class V cavities using the classification devised by G. V. Black. Amalgam, composite resin (in different formulations), glass ionomer, resin modified glass ionomer (RMGI) and compomer may all be considered appropriate restorative materials for class V restorations.

Why do teeth corrode?

Corrosion. This occurs chemically when acidic content hits the tooth surface such as with certain medications like aspirin or vitamin C tablets, highly acidic foods, GERD, and frequent vomiting from bulimia or alcoholism.

What is cause Hypercementosis?

Hypercementosis is excessive deposition of cementum on the tooth roots. In most cases, its cause is unknown. Occasionally, it appears on a supraerupted tooth after the loss of an opposing tooth. Another cause of hypercementosis is inflammation, usually resulting from rarefying or sclerosing osteitis.

How does carious lesion formation happen?

Summary. The caries process is initiated by activity within the biofilm and manifested in the underlying enamel or dentin. The caries lesion may be active or arrested, and reflects the activity in the biofilm. It should be considered the sign or symptom of the disease.

What are Class 5 lesions?

Carious class V cervical lesions are the result of chronic plaque accumulation at the cervical third of the tooth in conjunction with a significant intake of fermentable carbohydrates. An additional risk factor is reduction in salivary flow and salivary quality due to xerostomia.

What is a Class IV restoration?

The use of composite resins for class IV restorations is a procedure that demands the clinician to commit, from planning to execution, combining art and science using a minimal invasive approach that allows more tissue preservation with optimal aesthetic and functional outcome.

How are cervical caries treated?

Cervical caries, like any other type of caries, can be cured only with the help of a qualified dentist using special equipment. At home, you can only relieve pain symptoms. The doctor determines the treatment depending on the stage of development of the disease.

Which restorative material is selected for the permanent restoration of a Class I lesion?

The most common materials currently in use for the permanent restoration of carious lesions in posterior teeth are dental amalgam and resin‐based composite.

What are a dental assistant's responsibilities in a restorative procedure?

Restorative Procedures

The dental assistant prepares all the materials that will fill the tooth structure. The dental assistant prepares amalgam, resin-based composites or cast crowns for the dentist. Amalgam is an alloy that looks silver in color and is used to restore the function of the posterior teeth.

What is the main aim of restoration of carious lesion in Phase I therapy?

Reduce tissue removal treatment of carious lesions in both deciduous teeth and permanent teeth in order to save tooth substance, prolong the life of a tooth and reduce or avoid negative iatrogenic outcomes such as pain, anxiety and adjacent tooth damage.

How do you prevent carious lesions?

Fluoride compound, concentration, frequency of use, duration of exposure, and method of delivery can influence fluoride efficacy. Fluoride dentifrices are the most widely method of delivering topical fluoride. Fluorides may arrest carious lesions with or without prior removal of carious tissue.

What is a non cavitated carious lesion?

A non-cavitated caries lesion (also sometimes referred to as an early lesion, an incipient lesion, or a white spot lesion) is a demineralized lesion without evidence of cavitation.
