Perineural Injection Therapy Training for Dentists

Perineural injection therapy (PIT) involves the subcutaneous injection of a low-concentration buffered dextrose solution (typically 5% dextrose) along the course of superficial peripheral nerves that have become chronically irritated and inflamed. The dextrose interacts with TRPV1 receptors on sensory nerve fibers, reducing neurogenic inflammation and restoring normal nerve function. This mechanism addresses the underlying neural dysfunction rather than simply masking pain.

PIT has demonstrated clinical efficacy for chronic neuropathic pain conditions including headaches and migraines, chronic neck and back pain, lateral epicondylitis, Achilles tendinopathy, knee pain, post-surgical pain syndromes, and various other chronic musculoskeletal pain conditions that have a significant neuropathic component. It is particularly valuable for patients who have not responded adequately to conventional pain treatments.

Most patients require a series of four to eight treatment sessions spaced one to two weeks apart, though significant pain reduction is often noticed after the first two to three treatments. Some chronic conditions may require additional maintenance sessions. The course teaches you how to structure multi-session treatment protocols and track clinical outcomes to guide treatment duration.

PIT has an excellent safety profile because the injections are performed subcutaneously (not deep) using a very low-concentration dextrose solution rather than corticosteroids or other medications with systemic side effects. The most common side effect is mild, temporary discomfort at injection sites. The superficial injection depth and benign injectate make PIT one of the safest interventional pain procedures available.

Traditional prolotherapy (regenerative injection therapy) uses higher-concentration dextrose solutions (typically 15-25%) injected into ligament and tendon attachments to stimulate a healing inflammatory response. Perineural injection therapy uses much lower concentrations (5%) injected subcutaneously along superficial nerve pathways to reduce neurogenic inflammation. The targets, mechanisms, and concentrations are distinctly different despite both using dextrose.

Yes, PIT integrates well with other pain management modalities including joint injections, trigger point injections, physical therapy, regenerative medicine treatments, and chiropractic care. Many practitioners use PIT as part of a comprehensive, multi-modal pain management approach that addresses both neuropathic and nociceptive pain components simultaneously.

PIT requires minimal equipment — small gauge needles (typically 27-30 gauge), sterile buffered dextrose solution, syringes, and standard injection supplies. The low equipment cost and absence of expensive imaging or specialized devices make PIT one of the most accessible interventional pain procedures to add to a practice, with virtually no barrier to entry beyond proper training.

Yes, Empire Medical Training's Perineural Injection Therapy Training is fully CME/CE accredited. You receive certification documenting your training in PIT techniques along with earned CME/CE credits applicable to license renewal and professional development requirements for your specific healthcare profession.

Dentists frequently encounter patients with trigeminal neuropathic pain, post-extraction or post-implant nerve irritation, atypical orofacial pain, and TMJ-related neuropathic conditions. PIT provides a treatment option for these patients that targets neurogenic inflammation along affected cranial nerve branches using subcutaneous dextrose — an approach distinctly different from conventional dental pain treatments.

PIT for trigeminal and orofacial nerve conditions typically falls within dental scope as it involves subcutaneous injections of buffered dextrose within the head and neck region. The treatment directly addresses dental-relevant nerve conditions. Verify your state dental board's specific guidelines. Empire's certification documents your hands-on PIT training for credentialing purposes.

Conditions that may respond to PIT include trigeminal neuropathy, inferior alveolar and lingual nerve irritation following dental procedures, atypical facial pain, some TMJ-related neuropathic pain conditions, and chronic orofacial pain syndromes with neuropathic features. PIT is particularly valuable for patients who have not responded to conventional orofacial pain treatments.

In most states, dentists are authorized to administer botulinum toxin and dermal filler injections within the head, neck, and associated structures. Some states define this scope broadly to include cosmetic applications, while others limit dental injectable use to therapeutic and functional purposes. Empire recommends confirming your state dental board's specific guidelines. Our training provides the clinical certification recognized by dental boards nationwide.

Dentists have superior knowledge of facial anatomy, nerve pathways, and injection techniques compared to most other healthcare professionals entering aesthetics. Your daily experience with local anesthesia, precise needle placement, and patient management in the facial region gives you a significant head start. Empire's course builds on these existing competencies to add aesthetic-specific protocols, product knowledge, and treatment planning skills.

Dental practices that add aesthetic injectable services typically generate $100K-$300K+ in additional annual revenue, often from their existing patient base. Botox and filler treatments have high profit margins, create recurring revenue through maintenance appointments, and attract new patients who become dental patients as well. The crossover appeal is significant — patients who trust you with their smile naturally trust you with their facial aesthetics.
