The inferior alveolar nerve is at risk during surgical removal of impacted mandibular teeth and excision of benign tumors of mandible. Manual and/or mechanical instruments used in the close proximity of delicate structures do not allow the control of the cutting depth and can damage these structures by accidental contact. Piezoelectric surgery is a new and innovative bone surgery technique using the microvibrations of special scalpels at ultrasonic frequency so therefore soft tissue will not be damaged even upon accidental contact with the cutting tip. This article presents an alternative technique that uses piezoelectricity to minimize trauma to the inferior alveolar nerve, vascular tissues, or surrounding dental tissues.

Anesthetic effectiveness of mental/incisive nerve block versus inferior alveolar nerve block in mandibular first and second premolars with symptomatic irreversible pulpitis: A randomized clinical trial.
J Endod
January 2025
Department of Endodontics, Faculty of Dentistry, Cukurova University, Adana, 01380, Turkey.
Introduction: This study aimed to compare the effectiveness of mental nerve block (MINB) and conventional inferior alveolar nerve block (IANB) anesthesia during endodontic treatment of mandibular first and second premolars with symptomatic irreversible pulpitis (SIP).
Methods: In this randomized, double-blind, clinical trial, 120 patients undergoing endodontic treatment of mandibular premolars were randomly assigned to IANB (n=60) or MINB (n=60) using 4% articaine with 1:100,000 epinephrine hydrochloride. Pain levels were evaluated preoperatively and during cold tests, cavity preparation, and pulp extirpation using the Numerical Rating Scale (NRS).
Comparative Evaluation of 4% Articaine and 2% Lignocaine Anesthetic Agents in Children: A Split-mouth Randomized Control Trial.

Aim: The objective of the present study is to assess and compare the effectiveness of two different anesthetic agents, namely, 4% articaine and 2% lignocaine, in the extraction of primary molar teeth in children.
Materials And Methods: The study included 25 children requiring bilateral extractions of primary molar, with extraction performed on one side with 4% articaine and the contralateral side extraction with 2% lignocaine at two separate appointments. The anesthetic efficacy was evaluated objectively by assessing pain and the child's behavior at baseline, during injection and during extraction using the sound, eye, and motor (SEM) scale objectively, and subjectively using the faces pain rating scale (FPS).
Risk factors for inferior alveolar nerve injury associated with implant surgery: An observational study.

Department of Oral and Maxillofacial Surgery, Seoul National University Dental Hospital, Seoul, Republic of Korea.
Background/purpose: Inferior alveolar nerve (IAN) injury is the most serious complication associated with dental implant surgery, posing difficulties in treatment and potential for permanent disabilities. This study aimed to identify patient-related risk factors for IAN injury during implant placement and to investigate sensory disturbances depending on whether the implant was removed.
Materials And Methods: Twenty-eight patients with implant-related IAN injury were included.
Effectiveness of an External Cooling and Vibrating Device vs Counterstimulation in Reducing Discomfort of Inferior Alveolar Nerve Block in Pediatric Dental Patients: A Single-blinded Randomized Controlled Trial.
Int J Clin Pediatr Dent
December 2024
Department of Pedodontics, Government Dental College, Alappuzha, Kerala, India.
Background: Pain management in pediatric patients during dental procedures is very important. Here, the traditional method of behavior management is compared with novel methods.
Aim: To compare and determine the effectiveness of an external cooling and vibrating device vs counterstimulation with the conventional technique in reducing the fear and discomfort of pediatric dental patients aged 5-7 years during inferior alveolar nerve block (IANB).

Background: Sensory disorders of the inferior alveolar nerve, often arising from dental procedures, markedly impact the quality of life of patients. This article proposes a scoping review to analyze emerging trends in pharmacological treatment for these disorders, addressing scientific gaps and clinical practices.
Material And Methods: The review followed the PRISMA-ScR protocol, conducting data searches across various databases, including PubMed and Cochrane, until March 2024.
