Defenition

Chemomechanical caries removal

(CMCR)

is a non-invasive technique eliminating

infected dentine via a chemical agent.

This is a method of caries removal based

on dissolution.

History

The idea developed in 1970 while using NaOCl in endodontic treatment.

NaOcl is able to remove the organic materials in the root canals and dissolve the carious dentine tissues.

(Goldman and Kronman1976) GK101only attack the degenerated collagen fibers and soften the inner layer of carious dentine then instrument is used.

Caridex 1984 two bottle system

1. NaoCl

2. glycine, aminobutyric acid, sodium

chloride and sodium hydroxide.

3. Disadvantage

the large volumes of liquid used per cavity

preparation and the increased time

equired

Cariosolve 2009

It makes use of three naturally occurring amino acids (glutamic acid, leucin and lycine) .

Composed of two syringe

1. sodium hypochlorite (0.5%)

2. glutamic acid, lysine, leucine, carboxymethylcellulose, sodium chloride, sodium hydroxide and a red dye.

Mechanism of action

causes proteolytic degradation of the

already partially broken-down collagen in

the outer carious dentine.

followed by the removal of lesion using

specially designed non-invasive

instrument. This procedure is repeated

until all carious tissues are removed.

advantages

1. ability of selectively removing the outer layer of dentin

caries.

2. it does not attack the sound dentin as it is alkaline

3. Over-excavation of the cavity, thereby, is prevented.

4. Less perception of pain and more comfortable for

patient.

5. Less fear and anxiety to method, leads to less

discomfort to patients especially in children.

6. Removes only infected layer and leads to more tissue

preservation.

7. No pulpal irritation.

8. Well suited to the treatment of deciduous teeth, dental

phobic’s and medically compromised patients.

9. Better removal of caries in uncooperative patients.

10. Useful in physically handicapped patients.

11. Useful in patients with T.B like infectious diseases

(prevent droplet infection).

Disadvantages 1. Rotary and/or hand instruments may still be

needed for the removal of tissue Large volumes of solution were needed (200 to 500 ml) and the procedure was slow and also costly.

2. Only certain cavities were suitable for treatment by the technique and because of the time involved (10 to 15 min) and limited use, its popularity waned.

3. Although there were studies on the efficacy of caries removal by the procedure, studies on the long term success of cavities restored after CMCR treatment were lacking.

How to use it in clinic

1. Apply the gel with one of the hand

instruments.

2. Wait 30sec

3. Remove carious dentine with hand

instrument.

4. Reapt the procedure until no more

carios dentine is left.
