However, inferior alveolar nerve block (IANB) does not always result in successful pulpal anesthesia, during symptomatic irreversible pulpitis and has a high failure rate between 35% and 45%. Intrapulpal (IP) injection has been found to have increased efficiency and pain. The study aims to find the pain perception of 26G and 31G and the use of obturators in improving the efficacy of IP anesthesia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>Eighty patients with symptomatic irreversible pulpitis after the failure of IANB were recruited and divided into four groups to receive IP with Group I A: 26G with obturators, Group I B: 26G without obturators, Group IIA: 31G with obturators, and Group IIB: 31G without obturators.
