Abstract

Objective: The current study assessed the success of infiltration anesthesia versus inferior alveolar nerve block (IANB) anesthesia during (mobile and non-vital) teeth extraction in posterior mandible.
Materials and methods: In a prospective study, 120 patients were included to extract one tooth for each patient in the posterior mandible under local anesthesia either by local infiltration = 60 (18 males, 42 females); or IANB = 60 (32 males, 28 females). Comparing anesthetic success rate of the two techniques and time until onset of anesthetic action (min).
Results: IANB was successful in 100% of the patients, where infiltration anesthesia succeeded in 85%. In addition, duration until onset of action was found to be equal with p =(0.7)
Conclusion: Infiltration technique offers a simpler substitute with less complication compared to IANB in establishing effective anesthesia for mandibular mobile and non-vital posterior teeth during intra-alveolar dental extractions.
