“…The 'caries-infected' dentine, on the other hand, exhibited deformation of the architecture of the dentinal tubules, permanent denaturation of the collagen fibers, and significant bacterial infiltration. 16 Though the method of chemomechanical caries removal is a minimally invasive technique, there are contradictory results about the microhardness of residual dentin after its use. There are insufficient data available in the literature regarding the hardness of remaining dentine after caries excavation with CMCR agent Brix 3000 and hardness of remaining dentine after caries excavation with polymer burs.…”

Aim: To evaluate and compare microhardness of residual dentin in primary molars following caries removal with chemomechanical agent (BRIX 3000) and polymer burs (SS white). Materials and Method: Extracted maxillary or mandibular primary molars with proximal carious lesion, were selected with active carious cavities extending in to 2/3rd of dentin. The selected teeth were preserved in phosphate buffer saline solution no longer than 30 days. The selected teeth were separated into two experimental groups: group A- chemomechanical method – Brix3000 and Group B- slow speed polymer bur. After caries excavation the microhardness test was carried out on treated dentin using a Knoop indenter. Results: The results suggest a significant difference between among the groups Brix 3000â showed superior results compared to group B (Polymer burs) i.e., The results showed that the microhardness of the remaining dentine after caries excavation with Brix 3000 was found to be greater than the microhardness of the remaining dentine after caries excavation with Polymer bur. Conclusion: In conclusion of the current study, it can be stated that Brix 3000 may be utilized as a successful agent in minimally invasive caries excavation since Polymer burs showed partial removal of carious dentine.

Background This study was conducted to compare chemical, elemental and surface properties of sound and carious dentin after application of two restorative materials resin-modified glassionomer claimed to be bioactive and glass hybrid restorative material after enzymatic chemomechanical caries removal (CMCR) agent. Methods Forty carious and twenty non-carious human permanent molars were used. Molars were randomly distributed into three main groups: Group 1 (negative control) - sound molars, Group 2 (positive control) - molars were left without caries removal and Group 3 (Test Group) caries excavated with enzymatic based CMCR agent. After caries excavation and restoration application, all specimens were prepared Vickers microhardness test (VHN), for elemental analysis using Energy Dispersive Xray (EDX) mapping and finally chemical analysis using Micro-Raman microscopy. Results Vickers microhardness values of dentin with the claimed bioactive GIC specimens was statistically higher than with glass hybrid GIC specimens. EDX analysis at the junction estimated: Calcium and Phosphorus of the glass hybrid GIC showed insignificantly higher mean valued than that of the bioactive GIC. Silica and Aluminum mean values at the junction were significantly higher with bioactive GIC specimens than glass hybrid GIC specimen. Micro-raman spectroscopy revealed that bioactive GIC specimens showed higher frequencies of v 1 PO 4, which indicated high level of remineralization. Conclusions It was concluded that ion-releasing bioactive resin-based restorative material had increased the microhardness and remineralization rate of carries affected and sound dentin. In addition, enzymatic caries excavation with papain-based CMCR agent has no adverse effect on dentin substrate.

Background: Conventional method of using carbide burs on high-speed handpiece for caries eradication has long been shown to be quite successful. Nevertheless, it has several disadvantages, including heat generation, harmful effects on the pulp, the requirement for local anesthetic, excessive dentin removal, and patient discomfort. Objective: The aim of this study was to compare and assess time consumption and the caries removal effectiveness of two different minimally invasive caries eradication techniques using Smart prep bur II and Brix 3000. Materials and Methodology: Forty newly extracted carious human permanent premolars were collected from patients between the ages of fourteen and twenty-four years. Teeth were extracted for orthodontic reasons in most cases. Caries should be deep but without pulp involvement and all teeth have only one surface caries (mesial or distal Class II carious lesions). Samples have been collected, cleaned from any remnants or debris and stored in formalin solution until starting the experiment. According to the type of minimally invasive procedure, teeth were divided into two groups (n=20). Infected carious dentin for each group was removed using Smart prep bur II (polymer bur) or Brix 3000 (caries dissolving enzymes). After caries removal, cavity was checked by caries detector dye to ensure complete removal of infected carious dentin otherwise procedures were repeated. Two parameters were assessed: time consumption and caries removal efficacy for each minimally invasive type. Cavities were inspected by stereomicroscopy and caries removal was categorized after application of caries detector dye. Data was collected, tabulated and results was compared statistically. Results: Regarding the amount of time needed for soft caries eradication and the efficacy of total amount removed of infected dentine, there was no statistically significant difference found between the two techniques. Conclusion: within the limitation of this in-vitro study, both Smart Prep bur II and BRIX 3000 are efficient methods for caries eradication by minimally invasive approach. However, both are time consuming methods and dentist need to check well the cavity using caries detector dyes to ensure complete eradication of infected dentin that -in most cases- are not removed completely from the first trial by those methods.
