AIM: To compare the efficacy of supplemental anaesthesia using periodontal ligament injections (PDL) and intraosseous injections with the X-Tip system in terms of the measured heart rate and patient reported pain level.
METHODOLOGY: In this single-blind randomized clinical trial, 40 patients (22 women, 18 men) with irreversible pulpitis who had experienced unsuccessful pain management by inferior alveolar nerve block with 2% lidocaine and 1 : 100 000 epinephrine were selected. Patients were divided equally and randomly into two groups. Supplementary anaesthesia was provided through intraosseous injection with the X-Tip system (X-Tip group) or by PDL injection (PDL group). After each step of injection, pain severity was assessed using a visual analogue scale. Patient heart rate was recorded with a pulse oximeter. Data were coded and analysed using Mann-Whitney U-test with SPSS (version 16) software.
RESULTS: Anaesthetic success was obtained in 100% of X-Tip and 70% of PDL group patients after the first supplemental injection. Compared with the first PDL injection, the first intraosseous injection resulted in a significant increase in heart rate (P = 0.001); however, this increase was short-lived (mean increase: 9-10 beats per min). No significant difference in heart rate or anaesthesia success was observed between men and women.
CONCLUSION: Intraosseous injection using the X-Tip system was more effective than PDL injection as a supplementary anaesthetic for pulpectomy in mandibular molars or second premolars. However, the former resulted in a transient increase in heart rate.
