Lidocaine HCl 2% with Epinephrine 1:100,000 is widely regarded as the benchmark local anesthetic in dentistry, relied on for its rapid onset, consistent depth of anesthesia, and excellent safety profile. Decades of clinical use have affirmed its effectiveness for a broad range of procedures, making it a staple in nearly every dental operatory.
A Reliable, Fast-Acting Local Anesthetic
One of the primary advantages of lidocaine is its dependable onset time. Most patients achieve profound anesthesia within two to three minutes following infiltration, and slightly longer for nerve blocks. This predictable onset allows clinicians to plan procedures efficiently and maintain smooth workflow throughout the day. Compared with other amide anesthetics, lidocaine strikes a balance between potency and patient tolerance, minimizing discomfort during injection and reducing the likelihood of postoperative complications.
Why 2% Lidocaine is Widely Preferred
The 2% concentration provides strong and stable nerve blockade suitable for restorative procedures, periodontal therapy, endodontics, extractions, and minor surgical interventions. Its pharmacologic profile allows it to penetrate nerve membranes quickly, creating the reversible loss of sensation needed to keep patients comfortable without prolonged numbness that may interfere with daily activities.
Role of Epinephrine 1:100,000
The addition of epinephrine at a 1:100,000 ratio enhances lidocaine’s performance through controlled vasoconstriction. By narrowing local blood vessels, epinephrine reduces systemic absorption of the anesthetic, extends its duration, and allows for a drier surgical field. This is particularly beneficial during extractions, crown preparations, and soft-tissue procedures where visibility is essential.
Prolonged anesthetic action also reduces the need for reinjection, improving patient experience and minimizing chair time. The 1:100,000 concentration is widely considered the ideal balance for routine dentistry—providing sufficient vasoconstriction without excessive cardiovascular stimulation for the majority of patients.
Stability and Convenience of 1.7 mL Cartridges
Each box contains fifty 1.7 mL glass cartridges designed for compatibility with standard dental syringes. Glass cartridges preserve the sterility and stability of the solution better than plastic alternatives, ensuring smooth delivery and minimal risk of contamination. Their consistent volume helps clinicians deliver predictable doses during both infiltrations and block injections.
Clinical Versatility Across Procedures
Lidocaine HCl 2% with epinephrine remains one of the most adaptable anesthetics due to its moderate duration and suitability for nearly every everyday dental procedure. It performs effectively for:
-
Routine restorative dentistry
-
Scaling and root planing
-
Endodontic access and instrumentation
-
Simple and surgical extractions
-
Implant site preparation
-
Crown and bridge procedures
-
Minor soft tissue surgeries
Because of its excellent safety margin and familiarity among dental professionals, it is often the first choice for both adult and adolescent patients when indicated.
A Trusted Option for Modern Dentistry
With its strong track record, balanced pharmacology, and dependable clinical results, Lidocaine HCl 2% with Epinephrine 1:100,000 continues to stand as the trusted workhorse of dental local anesthesia. Its ability to deliver rapid, profound, and stable anesthesia—combined with ease of use—makes it an essential material for any dental practice committed to patient comfort and procedural efficiency.
