CAVITY
After the confirmation of SIP, the independent individual informed the single operator (SH) of which intervention should be administered. The clinician was informed about the appropriate intervention by utilizing the assigned labels (A, B) to ensure the clinician’s blinding. The researchers utilized online randomization software to assign eligible patients to either control or experimental groups (A, B). During the visit, the operator provided a standardized explanation of HP-VAS both verbally and in a written format to familiarize and train the patients in the study instrument. The patients documented the intensity of pain on HP-VAS by marking a vertical line on HP-VAS three times: pretreatment, after access cavity preparation (ACP), and after initial instrumentation. All the pre- and post-intervention research data were evaluated by a trained clinician (AA).
