Summary
The aim of this study is effect of premedication on success of inferior alveolar nerve block
injection. Sixty healthy adult volunteers including criteria, are participating. The patients
will be divided into 3 groups and will be randomly given one of premedications including 1)
10 mg Ketorolac, 2) 10 mg Ketorolac plus 1000mg Acetaminophen, and 3)Placebo, 45 minutes
before applying the injection. All patients will receive standard Inferior Alveolar Nerve
Block injection . Patients with no lip numbness and positive responses to cold and electric
pulp tests would be excluded from the study. Endodontic access preparation will be initiated
15 minutes after Inferior Alveolar Nerve Block injection. Pain during treatment will be
recorded using a Heft parker Visual Analog Scale(VAS). Success will be considered as no or
mild pain (VAS≤54) during caries/dentin removal, access cavity preparation and working
lengths measurements. Data will be analysed using Mann-U-Whitney and Kruskal-wallis tests.
