The randomization unit is individual. A randomization tool will be performed with the Randlist software (each patient entering the study will be assigned a number from 1 to 64 (for male and female) as a code and according to the arrenged numbers in the software will be randomized into four groups. The person who randomizes wont be aware of how to study, Blinding description: 1. The groups will be coded and presented to the statistical analyzer and the analyst wont be aware of the type of technique. 2. Anesthetizing will be done by one person and providing an access cavity and recording pain will be done by another person. The pain recorder wont be aware of the study technique. N/A Symptomatic irreversible pulpitis. Intervention 1: Intervention group1:IANB(Inferior alveolar nerve block) standard injection using prilocaine 3% solution (Prilocaine, Felypressin 0.03 IU/Darou Pakhsh,Iran ) will be done . After 15 minutes of block anesthesia and numbness of the lips, an infiltration on the buccal side of the affected tooth will be performed at a rate of 0.5 ml with a normal syringe with 27 gauge needle. After 5 minutes, the teeth will be isolated and the access cavity will be done. Intervention 2: Intervention group 2: After IANB injection and 15 minute timeout and anesthesia of the lips, intra-ligament injection with a special injection syringe and a short needle with 27 gauge will be done.Then, in the mesial and distal teeth, 0.2 ml of the solution will be injected and after 5 minutes the access cavity will be prepared. Intervention 3: Intervention group 3:After IANB injection and 15 minute timeout and anesthesia of the lips, second IANB injection will be done.and after 5 minutes the access cavity will be prepared. Intervention 4: Control group:In the control group, standard block injection using Prilocaine 3% solution (Prilocaine, Felypressin 0.03 IU/Darou Pakhsh,Iran) will be done . After 15 minutes and anesthesia of the lips, teeth will be isolated and access prepration will be done.
