The principles of the caries removal have changed greatly in the last decade. The use of local anesthesia with conventional techniqueshigh-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.
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.
