What is stepwise caries excavation?

What is stepwise caries excavation?

Stepwise excavation is an old concept but has become a research subject more, in recent years. It is a conservative approach to treat deep dental caries lesions where the exposure of the pulp is probable. In case of pulpal exposure, Root Canal Therapy (RCT) is the routine treatment method.

What are the 4 requirements for carious lesion development?

the patient’s (host) diet must consist of repeated digestion of refined carbohydrates, the host’s resistance to disease is decreased, the factor of time, and. there must be a specific bacteria (Streptococci or S.

What is deep caries management?

Traditionally, deep caries management was destructive with nonselective (complete) removal of all carious dentine; however, the promotion of minimally invasive biologically based treatment strategies has been advocated for selective (partial) caries removal and a reduced risk of pulp exposure.

How do you remove a deep Carie?

Deep caries may be selectively removed in either a one- or two-step process. In a one-step process, the lesion on the pulpal floor is removed until firm, leatherlike dentin is encountered. This firm, affected dentin may be remineralized18 and serves to protect pulpal health.

What is selective caries removal?

Selective caries removal (to firm or soft dentine): Caries is removed to dentine that is hard on probing in the periphery of the lesion, and to dentine which appears softened and still cuttable by excavators towards the pulp. After selective caries removal, a definitive restoration is placed immediately.

What is indirect pulp capping?

Indirect pulp capping occurs when the pulp tissue is close to the surface but not completely exposed. It usually includes two treatments spaced six to eight months apart. The indirect pulp capping procedure involves: Removing decay.

How do you diagnose caries?

Your dentist can usually detect tooth decay by:

1. Asking about tooth pain and sensitivity.
2. Examining your mouth and teeth.
3. Probing your teeth with dental instruments to check for soft areas.
4. Looking at dental X-rays, which can show the extent of cavities and decay.

What is caries risk assessment test?

The Caries Risk Assessment Tool is a research-based tool used to identify the risk factors that cause dental decay. It is also used to provide recommendations to reduce the risk of future cavities. It has been well documented that dental decay affects children throughout their childhood and into their early adulthood.

What material is used for pulp capping?

Two types of pulp-capping materials, calcium hydroxide and mineral trioxide aggregate, have been most commonly used in clinics, and an adhesive resin has been considered a promising capping material.

What RPM is caries removal?

By using the CeraTorque, carbides and other instruments can be run at both speeds—1,250 rpm for careful caries removal and 5,000 rpm for gross removal.

What is non selective caries removal?

Non-Selective Caries Removal (also known as complete caries removal): Both at the periphery of the cavity and pulpally, all carious tissue is removed to reach hard dentin, leaving no softened dentin.

What is partial caries removal?

An even more controversial approach is conservative or ultraconservative removal of carious tissue, often referred to as “partial caries removal.” In this method, the practitioner removes most but not all of the infected dentin, seals the cavity (with or without indirect pulp treatment) and proceeds with the …

What is the purpose of Dycal?

Dycal® Calcium Hydroxide Liner is a two-component, rigid-setting, self-curing material designed for use in direct and indirect pulp capping and as a protective liner under dental adhesives, varnishes, filling materials, cements, and other base materials.

What is the difference between indirect and direct pulp capping?

Pulp capping can be divided in to two categories: indirect pulp capping or direct pulp capping. For an indirect pulp cap, a carious lesion approaches the pulp tissue, but a pulp exposure does not occur. With a direct pulp cap, the pulpal tissue is exposed and a medicament is placed over the exposure.

Which test is used to identify the presence of dental caries?

Index test(s) The cornerstone of caries detection is a visual and tactile dental examination, and the ability of clinicians to accurately detect disease in this way has been researched for over half a century (Backer Dirks 1951).

What is the purpose of using a caries activity test?

These tests measure the degree to which the local environmental challenge favors the possibility of carious lesions. Caries activity tests are essential to: Establish an initial base-line level of cariogenic pathogens as a basis for future evaluation and preventive dentistry counseling.

Why do we use Dycal?

Why is calcium hydroxide used in pulp capping?

Calcium hydroxide continues to be the most accepted material for pulp capping. When calcium hydroxide is placed in contact with the pulp tissue, it preserves vitality, with no inflammatory response, stimulating the formation of a mineralized tissue barrier7.

What is a Class 5 dental restoration?

Color, shape and depth of a defect are important for restoration strength and color. Class 5 defects have tooth backing when viewed from the facial. Defect color shows through composite so thickness and translucency of composite material determines restoration color.

What is stepwise excavation for caries?

Stepwise excavation is an old concept but has become a research subject more, in recent years. It is a conservative approach to treat deep dental caries lesions where the exposure of the pulp is probable.

Why stepwise carious tissue removal in 2 stages?

The most recent inspiration for stepwise carious tissue removal in 2 stages originates from the knowhow on intralesion changes in deep carious lesions. The environmental change that takes place during the first stage of carious tissue removal is aiming for the arrest of the deep lesion, by placing a … Stepwise Excavation Monogr Oral Sci.

What are the different concepts in caries removal?
