A necessary part of the dental process is to allow a patient to feel comfortable and pain-free during surgical and restorative dental procedures. The most widespread local anesthetic injection for lower teeth is the inferior alveolar nerve (IAN) block. Despite this, the rates of ineffectiveness range from 10 to 39 percent.A study testing the efficacy of adding of mannitol to the typical anesthetic used in Ian blocks was presented by the journal “Anesthesia Progress.”
The participants were forty adult patients, who received an IAN block at each appointment at least once a week.
To compare the results of the effectiveness the standard anesthetic, lidocaine with epinephrine, was used alone and with addition of 0.5 M mannitol. Mannitol is a sugar alcohol that occurs naturally in fruits and vegetables. It is rapidly excreted by the kidneys and its impact is short-lived. However, it is effective in opening the perineurial membrane. There are studies, which show the perineurial barrier around the nerve does not allow complete diffusion of anesthetic into the nerve trunk, in cases of IAN block failure.
An enhanced permeability is provided by the addition of mannitol. When administered concurrently it increases the success of an IAN block.
The participants’ levels of pain were measured by an electric pulp test of their mandibular teeth every 4 minutes during the 60 minutes after the injections of anesthetic in the IAN block solutions.
In conclusion the significant increased effectiveness of the anesthesia with the addition of mannitol to lidocaine with epinephrine was shown.
Mannitol is basically being used in the hospital for people who have increase Intracranial pressure and edema. It's good to know that Mannitol can also increase the effectiveness of anesthetics like Lidocaine.

ReplyDeleteI better check with my dentist Bondi Junction if they know about Mannitol. I don't think they've used it with any of my treatments.
