comparison the effect of lidocaine inferior alveolar nerve block versus articaine lingual infiltration as primary injection on onset and duration of pulpal anesthesia in mandibular second molar with healthy pulp

the aim of present study is to compare the effect of lidocaine blocks with articaine lingual infiltration as primary injection on onset and duration of anesthesia of visitors of endo-department during 2016-2017. the distinct objectives of present study are: 1-determining qualified patients and assigning them to control and test groups 2-determining onset and duration of anesthesia for these two groups the present study was conducted in the form of clinical trials.all patients with anesthetic indication in mandibular second molar with healthy pulp and two indicative quadrants were studied.their quadrants were randomly categorized into two groups of test (articaine infiltration) and control (lidocaine blocks). the injector (syringe) had identical needle tip.the test group had articaine infiltration made in ceptodent (amount:1 carpool) and control group will be regarded as next quadrant on which the same person is administered with same syringe and lidocaine block instruments (made by Daro-Pakhsh company). for both groups,after injection start of anesthesia is recorded every minutes through electric pulp tester and it is recorded in information form no.2 . in addition,duration of anesthesia , time of anesthesia ( recorded every minute) is recorded in information form no.2 in the same method until anesthesia is over.time of start and duration of anesthesia were judged in two groups through t-tests. qualified individuals without systemic and neurologic diseases and sensitivity to anesthetic drugs,smoking and alcohol and drug addiction second mandibular teeth with healthy pulp and free from infection and swelling on both sides. in the present study,30 individuals offering 60 samples were analyzed.
