Comparative StudyAn ex vivo comparison of pressures within dental pulp space using conventional anesthetic technique versus needle-mounted obturator.
The intrapulpal (IP) injection technique is 1 of several ways of obtaining profound anesthesia. There is evidence to suggest that pressure is the primary factor in obtaining anesthesia using IP injection. This is an ex vivo comparison of pressures within dental pulp space using the conventional anesthetic technique versus a needle-mounted obturator technique. ⋯ IP injection with the obturator resulted in increased pressure at the apex of each tooth. This pressure increase may allow for increased anesthesia when IP injections are indicated.
