Comparison of the Efficacy of Inferior Alveolar Nerve Block and Digital Anesthesia in Pulpectomy of Mandibular Permanent Molars in Children

June 8, 2026 updated by: Nisanur Müdüroğlu, Inonu University

This study aims to compare the effectiveness of inferior alveolar nerve block (IANB) and computer-controlled digital anesthesia in achieving adequate anesthesia in pediatric patients presenting with acute dental pain and requiring emergency endodontic treatment of mandibular permanent molars. Achieving profound anesthesia in such cases can be challenging due to acute inflammation.

Participants will be randomly assigned to receive either conventional IANB or digital anesthesia. Pain perception during the procedure will be assessed using validated pain scales. In addition, physiological parameters including heart rate and blood pressure will be recorded to evaluate the stress response associated with each anesthesia technique. Anesthesia success will be determined based on the absence of pain during treatment and the need for supplemental anesthesia.

The findings of this study are expected to provide evidence-based guidance for selecting the most effective and comfortable anesthesia technique in pediatric dental patients.

Detailed Description

Achieving effective local anesthesia in pediatric patients presenting with acute dental pain remains a significant clinical challenge, particularly in mandibular permanent molars requiring emergency endodontic treatment. The success of conventional inferior alveolar nerve block (IANB) may be reduced in the presence of acute inflammation, leading to inadequate pain control and increased patient anxiety.

Computer-controlled digital anesthesia systems have been introduced as an alternative technique that allows for a more controlled and consistent delivery of local anesthetic solution. This may improve both patient comfort and the success of anesthesia.

The aim of this randomized clinical study is to compare the effectiveness of inferior alveolar nerve block (IANB) and computer-controlled digital anesthesia in pediatric patients with acute dental pain requiring emergency endodontic treatment of mandibular permanent molars.

Participants will be randomly allocated into two groups: the IANB group and the digital anesthesia group. All procedures will be performed under standardized clinical conditions. Pain perception during anesthesia administration and treatment will be evaluated using validated pain assessment scales.

In addition to subjective pain evaluation, physiological parameters including heart rate and blood pressure will be recorded to assess the stress response associated with each anesthesia technique. Anesthesia success will be determined based on the absence of pain during treatment and the need for supplemental anesthesia.

The results of this study are expected to provide clinically relevant evidence regarding the most effective and comfortable anesthesia technique for pediatric patients, thereby improving treatment outcomes and patient experience.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Anesthesia success during endodontic treatment
Time Frame: During the procedure
Anesthetic success will be defined as completion of endodontic treatment without the need for supplemental anesthesia. Pain during treatment will be assessed using the Visual Analog Scale (VAS; 0-10) and will be considered in the evaluation of anesthetic success. Higher VAS scores indicate greater pain perception and lower anesthetic success.
During the procedure

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Heart rate changes
Time Frame: Before the procedure, during anesthetic administration, during pulp chamber roof removal, during extirpation, and immediately after the procedure
Heart rate will be recorded at predefined time points to evaluate physiological stress response during anesthesia administration and treatment.
