Sumario:The methods of caries removal have been the subject of many studies over the last years. At present, methods involving the least tissue invasion have been outstanding in the field of surgical-restorative treatment. In this context, the Carisolv™ system has appeared as a less traumatic and less invasive approach, particularly in pedodontics. Thus, the objective of the present study was to carry out a comparative analysis of the dentinal structure of primary molars before and after the removal of carious tissue by mechanical (low speed drills and conventional dentinal curettes) and chemomechanical (Carisolv™ kit) procedures based on quantitative culture for cariogenic bacteria to determine the number of bacteria present in the carious dentine after both treatments. Sixty primary molars from children ranging in age from 4 to 8 years, with active occlusal caries in dentine, were divided into two groups (A and B) of 30 teeth each, with group A having been treated by the chemomechanical technique and group B by the mechanical technique. Dentin samples were placed in glass vials containing 1 mL thioglycolate broth and submitted to culture to determine the number of S. mutans and Lactobacillus per mg of decayed dentine. The results did not reveal significant differences between the two methods of caries removal; however, the chemomechanical method was more efficient in completely eliminating S. mutans (p=0.02). In summary, the present results confirm previous studies showing that the two methods are comparable in reducing Lactobacillus, but Carisolv™ is more effective in the elimination of S. mutans.
