Periowave: A Unique Anti-Inflammation Therapy that Yields Superior Patient Outcomes

It is widely understood that chronic periodontitis is due to the presence of subgingival Gram-negative bacterial biofilms proliferating at the junctional epithelium, in periodontal pockets deep beneath the gumline. Mechanical debridement (scaling) and root planing (SRP) is standard therapy for chronic periodontitis. While SRP is useful for the removal of the calculus, SRP unfortunately leaves the majority of the Gram-native biofilm in the periodontal pocket resulting in the need for retreatment every 3 months to control the disease. SRP alone is often inadequate for very deep pockets, for instance pockets that are 10-13 millimetres deep. Patients with deep periodontal pockets typically are referred to specialists for surgical intervention, especially when bone loss is evident. Photodisinfection is a non-antibiotic, light based therapy that offers a non-invasive alternative to surgery. Photodisinfection has been shown to instantly inactivate the Gram-negative bacteria associated with periodontal diseases, as well as the bacterial virulence factors responsible for triggering inflammation.  The key virulence factors of P. gingivalis (a primary perio-pathogen) include the cytotoxin lipopolysaccharide (“bacterial endotoxin or LPS”), proteolytic enzymes and many toxic low-molecular weight compounds such as hydrogen sulfide and ammonia.  The proteases in particular are thought to be responsible for the majority of periodontal tissue damage.  Photodisinfection destroys the LPS and other virulence factors, a significant advantage over conventional antibiotics and antiseptics. Periowave Photodisinfection, more importantly, offers a key advantage over other therapies as it was able to demonstrate direct and immediate inactivation pro-inflammatory cytokines. The Periowave Photodisinfection approach can directly inhibit LPS, reducing the risk of cytotoxic shock, and can substantially reduce protease activity, minimizing the risk of further tissue damage. Periodontal (gum) disease is a chronic disease affecting about half the adult population.  It is the leading cause of tooth loss, responsible for about two thirds of lost teeth.  Pain and cost factors result in the majority of diagnosed patients neglecting to address their gum disease. Periowave Photodisinfection technology, with its unique ability to simultaneously eliminate the underlying bacteria causing chronic gum disease as well as reduce inflammation, is an important stress free therapy benefitting both the patient and the dental clinician.  Periowave is a cost effective and pain-free approach to the treatment of gum disease, whether as a prevention therapy in early stages of the disease or as a possible alternative to surgery in later stages of the disease.
