A Gingivitis Case Study: Periowave

A recent case study using Periowave completed by Dr Robert Fortier, DDS Cert. Perio, Quebec

Patient Profile: 29-year old female, non-smoker, 7 months pregnant. Exhibiting pregnancy gingivitis with full-mouth gingival hyperplasia caused by combination of hormonal changes of pregnancy and anticoagulation therapy. Generalized 4-5 mm pockets with profuse bleeding on probing (Fig 1.1)

Treatment Protocol: Initial Periowave treatment: Full-mouth SRP and PW treatment was performed along with localized gingivectomy to remove gingival hyperplasia. Cessation of anticoagulant therapy at birth.

Second Periowave treatment: 10 months after initial PW treatment following full mouth debridement.

Result: 10 months after initial Periowave treatment: 8 months after birth and 1 month after cessation of breast feeding, restoration of oral health. Some 4-5 mm pockets with no BOP and reduced inflammation (Fig 1.2).

1 month after second Periowave treatment: Only 3 pockets of 4-5 mm on the lingual of teeth 46-47. All other areas healthy with 1-2 mm pockets (Fig 1.3).

A Moderate Periodontitis Case Study: Periowave

A recent case study using Periowave completed by By Catherine Fairfield, RDH, Alberta:

Patient Profile: 69-year old, non-smoker male with generalized chronic periodontitis. Regularly scheduled supportive periodontal therapy (SPT) with unresponsive 7 mm pocket depth with heavy bleeding on probing on mesial of #13 (Fig 1.1).

Treatment Protocol: Initial Periowave treatment: 6 days after SPT due to heavy BOP in 7 mm PD treatment site.

Second Periowave treatment: 5 months after initial PW treatment in 5 mm PD treatment site with moderate BOP at SPT appointment.

Result: 5 months after initial PW treatment: Mesial #13 reduced from 7 mm PD with heavy BOP to 5 mm PD with moderate BOP (Fig 1.2).

4 months after second PW treatment: Mesial #13 further reduced to 3 mm PD with light BOP (Fig 1.3).

Este es el caso de una mujer de 52 años proveniente del este de la India, quien cada 4 meses asistía a su clínica dental para recibir el mantenimiento correspondiente posterior al tratamiento periodontal. La paciente había sido tratada 3 años antes por periodontitis generalizada grave. En aquel tiempo, el tratamiento consistió en raspado y alisado radicular, en cuidados en casa, equilibrio oclusal y cirugía ósea. La paciente padecía presión sanguínea alta, la cual se controlaba con lisinopril (Prinivil®) una vez al día, pero en general, contaba con buena salud. La valoración dental, mostró una bolsa entre los dientes 43 y 42, de 6 mm de profundidad que se apreciaba inflamada y sangrante. El resto de la boca se encontraba saludable.

Este es el caso de una mujer hispana de 55 años, quien se quejaba de dolor de encías y pérdida de dientes. En general, tenía buena salud y no presentaba ningún padecimiento médico.

La valoración dental mostró que el arco superior contaba con los dientes 13, 11, 21 y 23. La paciente tenía una aplicación de acrílico maxilar que no le cabía correctamente. El arco inferior, se encontraba intacto y sin problemas restaurativos; tenía una acumulación de cálculo dental moderado, pero pocos indicadores de inflamación clínica. Al sondear, se encontró que la profundidad de las bolsas periodontales, se encontraba dentro de un rango de 3-4 mm. Las radiografías mostraron niveles de hueso normales. Los dientes maxilares mostraron inflamación grave, hinchazón y sangrado.

Tratamiento con Periowave™ y resultados

El arco inferior respondió adecuadamente al raspado y alisado rutinario, sin embargo, se utilizó Periowave™ en una sesión inmediatamente después del alisado, para atender la severa inflamación maxilar. Se alineó la aplicación parcial de acrílico con un alineador suave, como una medida temporal. A los 14 días, los dientes superiores respondieron favorablemente al raspado y alisado radicular, junto con el tratamiento de Periowave™ al mostrar una solución absoluta de la inflamación.

The Use of Antimicrobial Photodynamic Therapy in the Treatment of Periodontitis

By: Veronique Benhamou, DDS, BSc, Cert. Perio, FPFA, FADI, FACD


It has been known since the beginning of the last century that microorganisms can be killed by various combinations of dyes and light. Ancient Egyptian, Indian and Chinese civilizations used light to treat various diseases, including psoriasis, rickets, vitiligo and skin cancer. In 1901, Niels Finsen used light to treat smallpox and cutaneous tuberculosis and in 1903, he won the Nobel Prize for his work on phototherapy (Nature 2003, Dennis et al) However, the interest in antimicrobial Photodynamic Therapy (aPDT) was diminished concurrently with the introduction of antibiotics; it is only in recent years, with the emergence of antibiotic-resistant strains, such as methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecalis that a search for alternative treatments has stimulated a revival of interest on aPDT. It is an effective antibacterial therapy that involves the use of specific-wave light energy to activate a photosensitive compound (photosensitizer), which interacts with locally present molecular oxygen. APDT has the potential to be a powerful alternative to antibiotic therapy, particularly for the treatment of localized infections of the skin and the oral cavity. Microorganisms that are killed by this technique include bacteria, fungi, viruses, and protozoa. Read More

Periowave™ Case Study- Gingival Inflammation and Pain Due to Oral Lichen Planus

Case Report

This is the case of a 72-year-old Caucasian woman who presented with a complaint of gingival pain on 11 and 21 during eating and brushing. She had no significant medical history (Figure 1.1). She described discomfort from 11, 21 for the previous six months. Incisional biopsies were performed, and immunofluorescence suggested oral lichen planus. Since there is no cure for OLP, attempts were made to treat the symptoms with Lidex® and later tacrolimus, though these measures provided no relief.

PeriowaveTM Treatment and Results

The patient underwent one treatment session with PeriowaveTM. Within one week following PeriowaveTM therapy, the gingival inflammation had resolved (Figure 1.2) and the patient experienced complete relief from the presenting complaint of pain.

Periowave™ Case Study #3 – Unsuccessful Prior Periodontal Therapy

Case Report
This is the case of a 52-year-old East Indian female who was on regular four-month maintenance following previous periodontal therapy. The patient had been treated three years prior for generalized severe periodontitis. The treatment at that time consisted of scaling and root planing, home care instructions, occlusal equilibration, and osseous surgery. The patient was in generally good health apart from high blood pressure, which was stable on lisinopril (Prinivil®) once a day. The dental examination showed a 6 mm inflamed bleeding pocket that was evident between 43 and 42 the rest of the mouth was healthy.

Periowave™ Treatment and Results

Scaling and root planing with local anesthesia was used to treat 43 and 42, with adjunctive treatment with Periowave following the scaling. The patient was out of the country after treatment for several months, but did return for a 12-week follow-up visit, at which time the pocket probing depth was reduced to 3 mm with no signs of inflammation

Periowave™ Case Study #2 – Gingival Inflammation and Tooth Loss

This is the case of a 55-year-old Hispanic woman who presented with a complaint of sore gums and tooth loss. The patient was in otherwise good health with no serious medical problems noted or observed.

The dental examination showed the upper arch to consist of teeth 13, 11, 21, and 23. The patient had a poorly fitting maxillary acrylic appliance. The lower arch was intact with no restorative problems. The lower arch had moderate calculus formation, but few signs of clinical inflammation; probing pocket depths were generally 3- 4 mm. Radiographs showed normal bone levels. The maxillary teeth exhibited severe inflammation with engorgement and bleeding.

Periowave™ Treatment and Results

The lower arch responded to routine scaling and root planing.However, because of the severe maxillary inflammation, the PeriowaveTM system was used for one session immediately after scaling. The acrylic partial appliance was relined with a soft liner as a temporary measure. Within 14 days, the upper teeth responded to SRP and adjunctive PeriowaveTM treatment, with a complete resolution of inflammation.
