Outcome assessment
tooth, pain
INFILTRATION
The primary outcome was the evaluation of pain control during extraction of mandibular anterior teeth after the administration of only labial infiltration of either 2% lidocaine or 4% articaine local anesthesia without an additional lingual injection. The recorded pain value was assessed by a 10-points Visual Analogue Scale (VAS / cm), with a zero end that denotes no pain and a 10-end that represents the maximum pain sensation. Furthermore, the necessity for re-administering anesthesia was considered a failure. A descriptive analysis of the demographic variables, tooth type, and the causes of extraction was performed.
