HELSINKI: A recent Finnish study titled "Effects of Regular Antibacterial Photodynamic Therapy on Oral Hygiene in Elderly 24-Hour-Care Residents" underscores the urgent need for innovative solutions in oral care. Presented at the American Association of Oral and Maxillofacial Surgeons (AAOMS) Annual Meeting in Orlando, Florida, the research highlights the potential of light-activated antibacterial therapy to combat common oral health issues like gingivitis and periodontitis.
Despite progress in dental care, maintaining oral hygiene in long-term care facilities remains a persistent challenge. According to Dr. Jaana Helenius-Hietala, DDS, PhD, Deputy Chief Dentist at Helsinki University Hospital, oral health among elderly residents in institutional care is alarmingly poor, with significant plaque accumulation and high incidences of periodontal diseases. These issues not only affect oral health but also contribute to systemic illnesses such as aspiration pneumonia, dementia, and cardiovascular diseases.
The Finnish study, conducted across two elderly care units in Helsinki, explored the efficacy of dual-light photodynamic therapy as a supplemental treatment to traditional oral hygiene practices. The therapy combines a light-activated antibacterial agent with a specific wavelength of light to target harmful bacteria in dental plaque, achieving significant improvements in oral health.
The study involved 31 elderly participants, each retaining at least 10 teeth. Subjects were divided into two groups: one receiving self-care guidance and the other receiving the same guidance alongside antibacterial light-activated therapy twice weekly.
“This therapy not only reduces harmful bacteria but also addresses dry mouth—a common issue among elderly individuals on multiple medications,” noted Dr. Helenius-Hietala.
The antibacterial method uses a photosensitizing agent applied to teeth, activated by light to produce reactive oxygen species that eliminate bacteria. This non-invasive treatment was developed through collaboration between dental professionals, microbiologists, and photodynamic therapy experts. While not yet available in the U.S., it is CE-marked in Europe and shows great promise for revolutionizing oral care globally.
Dr. Tommi Pätilä, a cardiovascular and transplant surgeon and one of the method's developers, emphasized the importance of oral hygiene in reducing risks associated with poor dental care, particularly in elderly populations. “Neglecting oral hygiene increases the likelihood of comorbidities, making innovative approaches like this essential,” he stated.
