What this trial studies

This clinical trial investigates the effectiveness of the Lumoral device, which utilizes dual-light photodynamic therapy, as an adjunct to non-surgical periodontal treatment in smokers with Stage III and Grade C periodontitis. Participants will be divided into two groups: one will use the Lumoral device nightly for 10 minutes before oral hygiene, while the other will follow standard oral hygiene without the device. Both groups will receive non-surgical periodontal treatment and will be monitored for 6 months to assess biofilm removal and host response. The study aims to determine if the Lumoral device enhances treatment outcomes compared to conventional methods alone.

Who should consider this trial

Good fit: Ideal candidates are smokers aged 35 and older with Stage III and Grade C periodontitis.

Not a fit: Patients who do not smoke or smoke fewer than 10 cigarettes per day may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved periodontal health and better treatment outcomes for smokers suffering from periodontitis.

How similar studies have performed: While the use of photodynamic therapy in periodontal treatment has been explored, this specific approach with the Lumoral device is relatively novel.
