Pain Assessment During Chemo-Mechanical and Smart Burs Caries Removal Versus Atraumatic Restorative Treatment in Carious Primary Molars

Pain Assessment During Chemo-Mechanical and Smart Burs Caries Removal Versus Atraumatic Restorative Treatment in Carious Primary Molars: A Randomized Clinical Trial

The aim of the clinical trial is to assess pain during Atraumatic Restorative Treatment (ART), Smart Burs and Chemo-mechanical Caries Removal (CMCR) in primary molars.

The principles of the caries removal have changed greatly in the last decade. The use of local anesthesia with conventional techniques"high-speed hand piece" increase the fear and anxiety of the child. Minimally invasive techniques reduce the pain and anxiety of the child by eliminating the use of local anesthesia.

In ART, soft carious tissue is removed by hand instruments. Although this technique is very simple.

Moreover, Smart Burs are more efficient in removal of soft infected dentine than ART leaving the affected dentin intact; as when they touch hard dentin, they become dull.

Finally, the recent effective method of caries removal is CMCR. The chemical agent contains proteolytic enzyme which destructs partially degraded collagen, leaving the infected dentin soft and easy to be excavated.

Therefore, the aim of this study is to assess pain during Atraumatic Restorative treatment, Smart Burs and Chemo-Mechanical Caries Removal in primary molars.
