Anesthetic success of supplemental infiltration in mandibular molars with irreversible pulpitis: A systematic review

AIM: To systematically review the anesthetic success rates of inferior alveolar nerve block (IANB) injection technique alone with that of combination of IANB and supplemental infiltration (SI) technique when used for pulpal anesthesia of mandibular posterior teeth with irreversible pulpitis during endodontic treatment. SETTINGS AND DESIGN: The study follows a longitudinal study design involving original research. MATERIALS AND METHODS: Electronic databases were systematically searched for randomized controlled clinical studies. Studies were selected by predefined inclusion and exclusion criteria. STATISTICAL ANALYSIS USED AND RESULT: The statistical analysis used was based on the results of the original research. All the included studies showed that there is the difference in the values comparing the two techniques, but the data are not statistically significantly different. CONCLUSION: Based on this review, the better anesthetic efficacy of the SI was observed.
