2.6. Intervention
pulpal bleeding, tooth, pulpal pain, pain
ENDO, COLD
The patients were diagnosed with SIP based on pain history (spontaneous, and lingering pulpal pain), and confirmed by exaggerated response of the offending tooth to cold sensibility testing utilizing Endo-Ice. The offending tooth’s response to cold sensibility testing was compared to a similar unaffected contralateral tooth (Control), and the diagnosis was verified clinically by directly observing the pulpal bleeding upon access opening. Only the teeth with normal periapical tissues (verified with periapical radiographs), and negative responses to palpation and percussion tests were included in the study.The patients were assigned to the control group or experimental group, containing 76 patients each, according to the previously explained methodology. Before receiving the anesthetic injection, the patients were taught and then requested to score their pain levels using the Heft–Parker Visual Analogue Scale (HP-VAS) (Initial instrumentation (Local II) and ACP were done using a high-speed handpiece and diamond round and Endo Z burs. Successful blocks were denoted as mild to no pain on II and during endodontic ACP, scored using HP-VAS [A total of 170 patients were initially assessed for eligibility. Out of those, 18 patients were excluded: 10 did not fulfill the criteria for inclusion and 8 refused to take part in the RCT. The final participant count for the trial was 152 with 98 males and 54 females. The participants were allocated randomly, to either the control or the experimental group (n = 76 each group), to assess the efficacy of the anesthetic agents under investigation.
