The Use of Antimicrobial Photodynamic Therapy in the Treatment of Periodontitis

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

INTRODUCTION

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 #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.

Periowave™ Case Study #1 – Generalized Severe Bleeding On Probing

My patient was a 30-year-old Caucasian woman who complained of bleeding gums over the previous 12 months. She described severe bleeding with eating or brushing.

Her medical history revealed no significant findings. She had recently undergone a complete medical examination with extensive laboratory testing with no significant findings. She had tried seeing a naturopathic physician and had tried a non-yeast diet for the control of her gingival bleeding with no improvement. She was on no medications.

The dental examination revealed generalized severe bleeding on probing. Pocket probing depths were in the 4 mm range, except for a 7 mm pocket distofacial #13, and a 5 mm pocket mesiofacial #23. Minimal plaque deposits were found and her home care was good. This patient had a history of regular 6-month scaling and there was minimal calculus. Her last scaling was within one month with no improvement. There was little to no clinical inflammation. Occlusion, tooth position, and mobility patterns were normal. No restorative problems were noted.
