Periodontitis is a chronic inflammation of periodontal supporting tissue caused mainly by local factors. If gingivitis is not treated in time, the inflammation may spread from the gingiva deep into the periodontal membrane, alveolar bone and cementum and develop into periodontitis.
Currently based treatment of periodontitis with gum on clean governance, such as mechanical scraping ruling way under the gum as the main treatment for clearing up the dental calculus and plaque on teeth, to have certain effect, but because of the limitations of mechanical way, they are no good cleaning the inflammatory granulation tissue inside the periodontal pocket, contains a large number of pathogenic bacteria group, also affect the gum adhesion situation again, This is one of the important factors that periodontitis is easy to repeat.
Laser makes use of the photothermal effect. On the one hand, after the optical fiber penetrates into the bag, the inflammatory granulation tissue is attached to the optical fiber through the thermal effect, so as to achieve the purpose of cleaning the granulation tissue in the bag. On the other hand, laser has the function of sterilization and anti-inflammatory, and can kill the bacteria in the bag at the same time.
The research shows that laser can deal with the inflammatory granulation tissue in the inner wall of the periodontal bag and the disinfection of the bag, and solve the traditional way in the treatment of periodontitis in the absence of thorough cleaning abuses.The effect of laser combined with conventional mechanical curettage is better than that of single mechanical treatment.
