Minimal intervention is a new concept for the restorative dentistry that integrates prevention, remineralization and minimal invasion for the placement and replacement of restorations.

INTRODUCTION

• The original approach to the treatment of caries developed by G.V. Black (1899) was purely surgical. • He thought that the only effective method of eliminating the disease was to completely remove all of the demineralized areas to tooth structure and rebuild it with an inert restoration.

A number of problems arise from this approach:

• First, it fails to recognize that cavitation is essentially a symptom of a bacterial disease. • Second, it denies the ability of the. tooth structure to remineralize and heal.

PRINCIPLES OF MINIMAL INTERVENTIONAL DENTISTRY

- Control the disease through reduction of cariogenic flora. - Remineralize early lesions.
- Perform minimal intervention surgical procedures as required (ART, Air abrasion). - Repair rather than replace.

EARLY DETECTION

- Laser fluorescence (Diagnodent)
- Ultraviolet-induced fluorescence
- Caries detecting dyes
- xeroradiography

REMINERALIZATION

It is possible to arrest and even reverse the mineral loss associated with the caries at an early stage, before cavitation takes place. Enamel and dentin demineralization is not a continuous, irreversible process. Though a series of demineralization and re-mineralization cycles, the tooth alternatively loses and gains calcium and phosphate ions, depending on the microenvironment.

ADVANCES IN CAVITY PREPRATION

• Air abrasion
• Lasers
• Chemo mechanical Cavity preparation
• Sonic oscillating system
• Tunnel restorations

MODIFYING THE MICROFLORA

• A significant correlation between the prevalence of Streptococci mutans in saliva increment of new caries lesions was obtained. • Lactobacilli along with Streptococci mutans are also related to root surface caries. • Using 0.2% chlorhexidene as a water-based gel or an...
