2TheApex:  Bilateral Nerve blocks were more successful (38% Uni- vs. 64% for Bilateral)

Mandibular teeth with Irreversible Pulpitis are the most challenging to gain profound anesthesia.  Due to some cross-innervations depositing anesthetic at BOTH mental foramina was found to be more successful that just one. Of course a Mental Nerve block may be preferred by patients since the tongue is not numb and it has a faster onset of action than an inferior alveolar nerve block.
