Introduction: The anticipation of pain experienced through dental treatment is
usually because of local anesthetic injections and a high-speed handpiece, especially
in children. Smart Burs II does not require local anesthesia; therefore, it can mitigate
the discomfort encountered during dental interventions and circumvent dental anxiety.
Aim: We aimed to evaluate the duration required for caries removal by Smart Burs II in
contrast to carbide burs, as well as the level of pain reported by pediatric patients during
the application of each method. Methods: Thirty permanent first molars that met our
criteria were included in the study. These molars were present in children aged between
8 and 11 years and exhibited class I occlusal caries. Participants were categorized
into two groups on the basis of random allocation. In Group I, which consisted of 15
participants, caries removal was performed using SmartBurs II. In Group II, which
comprised 15 participants, a conventional carbide bur was used for caries removal.
The duration of the caries removal procedure was recorded in seconds for both groups.
Patient perceptions of treatment were determined using the facial image scale (FIS).
Results: According to the statistical analysis, SmartBurs II resulted in a longer duration
and lower recorded pain scores than carbide bur. Conclusions: The employment of
SmartBurs ΙΙ necessitated an extended duration for caries removal and resulted in a
significant reduction in pain sensation during the extraction of infected dentin compared
to using traditional carbide burs.
