Summary

A more biological and conservative technique of caries removal has emerged with minimally invasive restorative dentistry's advent. As a result, Smart Burs II has become a self-limiting, sensitive tool for removing caries. The current study aimed to validate and contrast the polymer burs' efficacy (Smart Burs II) versus conventional burs (Carbide burs) for infected carious dentin's selective removal in permanent first molars. Thirty permanent first molars fulfilling the inclusion criteria were chosen in 8-11 years old children with class I occlusal carious lesions. Group 1 (n=15) and Group 2 (n=15) were randomly assigned to have carious dentin removed utilizing standard carbide bur and a smart Bur II, consecutively. By employing caries detector dye, the effectiveness of caries removal was quantified as 0, 1, 2, 3, 4, or 5. The volume of removed carious tissue was recorded using impression material which was inserted into a calibrated insulin syringe. A statistically significant difference was discovered in the volume of removed carious tissue between both groups, while the efficiency of caries removal using either bur has no significant difference. Smart Bur II was more conservative in the carious dentin's removal than carbide bur. Smart Bur II was as efficient as carbide bur in caries removal.

Conditions

  • Dental Caries in Children

Interventions

DEVICE

caries removal by carbide bur

caries was removed using a slow-speed handpiece and round carbide burs in sizes #12, #14, and #16, based on the lesion's size. When hard dentin was found using a dental probe, carious dentin removal was stopped.

DEVICE

caries removal by polymer bur II

carious tissue was removed utilizing smart polymer burs of sizes #4, #6, and #8, depending on the cavity's size, running at a slow speed without water coolant, in circular motions from the center of the lesion outward. Carious dentin removal ceased when the instrument became macroscopically abraded and sharpened and could no longer remove tooth tissues.
