Evaluation of effectiveness and efficiency of caries removal by chemo-mechanical versus atraumatic restorative technique: an in-vitro experimental study

Abstract

Abstract:

Introduction: Advancement in minimally invasive dentistry in restorative dentistry have led to a giant leap in innovation. However, the effectiveness and efficiency of these methods require further scientific exploration to be incorporated into clinical practice.

Material and Methods: The study included 50 extracted human permanent molars with Class I carious lesions, characterized by distinct cavities extending into dentin (ICDAS score 5). Each sample was sectioned through the center of the carious lesion to obtain two equal halves. These halves were randomly allocated into two groups: Group I – ART (n = 50) and Group II – CMCR (n = 50). Caries removal was performed following standardized protocols for both groups. The efficiency was measured by recording the time required for complete caries removal, while the effectiveness was assessed using a caries detector dye.

Results: CMCR (4.69 ± 1.22 min) was more efficient than ART (5.89 ± 1.27 min) in complete caries removal (p<0.05). Single use of CMCR was required for complete caries removal in 80% of the specimens, while only 52% of the specimens were deemed caries free after single attempt of ART (p<0.05). There was statistically significant difference in effectiveness of caries removal between the groups.

Conclusion: CMCR is an effective and efficient technique that may serve as a viable alternative in minimally invasive dentistry for management of dental caries.
