Summary

The aim of this clinical study is to evaluate the success of buccal infiltration (BI) anesthesia + intraligamentary (ILI) anesthesia between inferior alveolar nerve block (IANB) anesthesia + buccal infiltration anesthesia in mandibular molar teeth with acute symptomatic irreversible pulpitis.The main questions it aims to answer are: * Does the anesthesia techniques adequate to perform root canal treatment painlessly? * Which technique achieved pulpal anesthesia? Participants were allocated in two groups according to the randomization blocks, with a total of 25 patients in each group. In IANB + BI anesthesia techniques, a total of approximately 2.8 ml of anesthetic solution, 1.8 ml + 1 ml, was applied, while for BI + ILI, a total of approximately 1.72 ml, 1 ml + 0.72 ml, was administered. Then, root canal treatment was performed. Researchers were compared the success of anesthesia techniques in different stages of root canal treatment.

Detailed description

A total of 50 patients, aged between 18-65, who were diagnosed with symptomatic irreversible pulpitis of the mandibular molar tooth, were included in this study. The patients were allocated in two groups according to the randomization blocks, with a total of 25 patients in each group. In IANB + BI anesthesia techniques, a total of approximately 2.8 ml of anesthetic solution, 1.8 ml + 1 ml, was applied, while for BI + ILI, a total of approximately 1.72 ml, 1 ml + 0.72 ml, was administered. After the anesthesia, a rubber dam was placed on the associated tooth of the patient for root canal treatment, the endodontic access cavity was opened, and canal preparation procedures were started. The pain levels felt by the patients during the endodontic treatment stages (starting the treatment, opening the endodontic access cavity and pulp extirpation) were determined by Heft-Parker VAS (HP-VAS) scale. Anesthesia was considered successful in patients who felt no pain (HP-VAS ratio = 0) or mild pain (HP-VAS ratio ≤ 54) during the procedures.

Interventions

Type	Name	Description
DEVICE	Inferior Alveolar Nerve Block Group	A standard IANB injection with a conventional dental injector and a 27-G needle. After determining the injection site and performing aspiration, 1.8 mL of solution was injected at a rate of 1 mL/min to block the inferior alveolar nerve. After achieving lip anesthesia, infiltration was performed at the buccal side of the affected tooth with 0.5 mL using a normal syringe and a 27-G needle. The needle insertion point was the middle of the mesiodistal distance of the crown. Five minutes later, the teeth were isolated and the endodontic procedure was started.
DEVICE	Intraligamentary Injection Group	An infiltration was performed at the buccal side of the affected tooth with 0.5 mL using a normal syringe and a 27-G needle. Then, an intraligamentary injection was performed with a special pressure injection syringe (Sopira Citoject, Kulzer, Hanau, Germany) and a 30-G needle. The needle was placed alongside the tooth and inserted at a 30 angle relative to the longitudinal axis of the crown with the needle between the teeth and the bone. Then, in the mesiobuccal, distobuccal, mesiolingual and distolingual portions of teeth, 0.18 mL of the solution was injected. Five minutes later, the teeth were isolated and the endodontic procedure was started.
