Clinical Comparison of Cariclast Gel and Rotary Drilling Technique for Caries Removal in 2d Primary Molars

Clinical Evaluation of Pain Perception and Patient Acceptance During Chemomechanical Caries Removal Using Cariclast Versus Conventional Caries Removal in 2nd Primary Molars With Occlusal Caries in Children: A Randomized Clinical Trial

This randomized clinical trial aims to compare two different methods of caries removal in primary molars: the chemomechanical technique using Cariclast gel and the conventional rotary drilling method. The study will evaluate and compare the pain perception, patient acceptance, and operative time associated with both techniques in children aged 5-7years.

Dental caries is one of the most common chronic diseases in children, and the management of carious lesions in primary teeth should be both effective and minimally invasive. Traditional caries removal using rotary instruments is associated with discomfort and anxiety among pediatric patients.

Chemomechanical caries removal (CMCR) agents such as Cariclast have been developed as a more conservative and less traumatic alternative. Cariclast works by softening the infected dentin chemically, allowing its gentle removal without pain or vibration.

This randomized controlled clinical trial will compare Cariclast with the conventional rotary drilling method regarding:

Pain perception assessed using the FLACC scale.

Patient acceptance evaluated using the Visual Analog Scale (VAS).

Operative time required to complete the caries removal procedure.

All procedures will be performed on cooperative children with occlusal caries in primary molars, without pulpal involvement, attending the Pediatric Dentistry Department, Faculty of Dentistry, Cairo University.

  1. children aged 4-7 years
