Objective: Palatal infiltration of Local Anesthesia (LA) for maxillary tooth extractions is painful. One of the techniques for reducing the discomfort of this injection is to avoid it altogether. Given enough time, LA given only as buccal infiltration diffuses to reach and anaesthetize the palatal tissues. The aim of this double blind randomized controlled trial was to test the hypothesis that LA infiltrated by dental students only into the buccal tissues should be adequate for maxillary tooth extraction. Patients & Methods: Fifty adult patients presenting for single tooth maxillary extractions were randomly allocated between to two groups. The control group received palatal injections of 0.1 ml 2% Lidocaine with 1:100,000 epinephrine, while the experimental group received a similar amount of saline (placebo). Extractions performed without further administration of LA were categorized as successful. Results: Palatal infiltration of lidocaine with epinephrine was significantly more effective than saline (p=0.002). Overall buccal infiltration alone was successful in 28% patients, with a 40% success rate in the posterior maxilla. Conclusion: Results suggest that dental students should as a matter of routine extract maxillary teeth with both buccal and palatal infiltration of LA, while buccal infiltration by itself may be considered in selected cases for the posterior maxilla.
