Evaluation of Chemo-mechanical Caries Removal Materials in Caries Removal

Effectiveness of Papain-based Materials Compared With NaOCl-based Materials in Chemo-mechanical Caries Removal: A Randomized Controlled Trial

• The evolution of conservative dentistry that adopts the preservation of tooth structure and affected dentin that can remineralize and save the pulp from exposure, in addition to pain and fear that companies' traditional caries removal methods had led to the development of chemomechanical caries removal materials (CMCR). The old generations of CMCR agents were NaOcl-based materials which have disadvantages such as odor taste, Unpleasant smell, high cost, Limited shelf life, and time consumption. • All of the reasons described led to a new generation of CMCR materials depending on Enzymes such as Papain. Brix3000 and Papacarie duo are Papain-based materials with promising effects in caries removal and fewer disadvantages. Selecti-solve is a dental gel whose active ingredient is papain enzyme, it removes dental caries without the need for anesthesia and is selective for the infected dentin layer only which avoids the unnecessary loss of dentin, enamel breaking, and pulp exposure. This study aims to evaluate the efficacy of Papain-based materials compared to old NAOcl-Based materials in reducing the disadvantages of CMCR agents.

In previous literature, there has not been any study that compared the whole group of chemo-mechanical caries removal materials with such a unique collection of Papain-based CMCR agents. Papain-based agents could be promising materials in the evolution of Atraumatic Restorative treatment (ART) and Chemomechanical Caries removal methods that support conservative dentistry and the conservation of tooth structure and pulp vitality. Brix3000 has EBE technology (Encapsulating Buffer Emulsion) that claims to elevate the efficiency of Papain Enzyme and permits the use of a higher concentration of Papain 3,000 U/mg in the whole material (10%). Papacarie Duo has a unique combination of the main component of Papain Enzyme 6,000 U/mg and a small percentage of chloramine t that claims to increase efficiency and reduce the side effect of chloramine-based CMCR materials. Selecti-solve is a new material that consists of Papain as the main product and has promising effects in chemo-mechanical caries removal methods.

The efficacy of caries removal will be assessed by a sharp probe aided by Caries Detector dye. The Cavity will be inspected after every application by a sharp probe to feel any tacky sensation in dentin, when it is all hard dentin, caries detector dye will be applied to aid the investigation. Caries detector dye will be left for 10 seconds and then rinsed with water, it will stain the organic matrix of less mineralized dentin so the cavity should be stained homogeneously so high-intensity colored spots refer to infected dentin and it will be removed.

Time from the beginning of the caries excavation to the end of the process will be recorded in minutes using a stopwatch.

Visual analog scale (VAS) will be used to evaluate the pain perception during the procedure of caries removal. The patient will be asked to choose a number from 0 to 10 matching the intensity of his or her pain experience during the procedure. The higher the score, the more painful the procedure is.
