Comparative Evaluation of the Effectiveness of Intraligamentary and nerve block Injections during tooth preparation: A Randomized Controlled Trial

Abstract

Introduction- Patients decline dental treatments due to the pain being unbearable. Local anesthesia(LAs) act by blocking the sensory conduction of harmful stimuli from reaching the central system of pain during dental treatment, it is also useful in managing fear induced anxiety states. Intraligamentary anesthesia has been widely utilized in dental practice within recent years.

Materials and methods- Patients with a chief concern of fixed replacement of missing teeth participated in the study. The study was performed on patients who were undergoing fixed partial denture treatment which included 112 males and 88 females participants with ages ranging between 18 and 40 years old and who were systemically healthy. Patients in GroupA were injected LA anesthetized using intraligamentary infiltration, whereas patients in Group B were injected with LA anesthesia using nerve block and VAS score was evaluated.

Results- In maxillary arch, Pain during the procedure in the maxillary arch was lesser (p<0.05) in case of intraligamentary (1.62 ± 0.76) than the posterior superior alveolar nerve block(1.87 ± 0.80). In the mandibular arch, pain during the procedure (p<0.05) for intraligamentary (1.62 ± 0.763) and posterior superior alveolar nerve block (1.87 ± 0.800).

Conclusion- Intraligamentary injections are useful on patients with bleeding disorders, as they eliminate the risk of encountering blood vessels during injections as in case of nerve blocks. Intraligamentary LA helps in reducing the toxicity of LA in the patients.
