Numerous alternative therapies developed to enhance periodontal therapy effectiveness. The 940 nm wavelength of the diode laser has the capability of being an antibacterial tool in addition to its role in improving wound healing.

Material and methods

The current study included 77 periodontal pockets obtained from 3 patients suffering from chronic periodontitis who had treated at a private clinic in Baghdad, Iraq with an initial probing depth (IPD) ranged from 4-16 mm. Diode lasers with a wavelength of 940 nm were used for the therapy, which lasted for three months with twice-weekly recalls and a follow-up assessment after six months.


After twelve weeks of treatment, the probing depth were reduced significantly to less than half their initial depth that measured in the first visit. This improvement occurred concurrently with a highly significant increment in the alveolar bone lengths after receiving the treatment for 12 weeks that persist to increase even after the end of the exposure to 940nm diode laser by three months which is associated with bone bio-stimulation.


When utilized in accordance with the right protocol, the diode laser 940 nm can be perceived as a potential periodontitis therapy since it rapidly decreases probing depth while increasing bone bio-stimulation.
