About

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.

Full 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.
