The main cause of inflammatory disease of periodont is vital functions of conditionally pathogenic microflora of oral cavity. Gingivitis is an inflammation of the gums caused by plaque and bacteria accumulation [1]. Antimicrobial phototherapy is successfully used for treatment of various inflammatory diseases [2,3]. Low-intensity light irradiation would be alternative therapeutic technique of treatment of for the patients who have contra-indications to the use of medicaments. In the past few years the development of light emitted diodes (LEDs) has advanced them to a stage where their use in phototherapy is possible [4]. We proposes the use of low intensity light diode toothbrush with irradiation at wavelength 405 nm as new aid of individual hygiene. The goal of the pilot studies is estimation of the efficacy of the treatment of inflammatory disease of gum mucosa with tooth brushing in combination with phototherapy.
Sixty subjects from 17 to 39 years old of both sexes with light to moderate gingivitis were enrolled. I group included the volunteers, who were treated by blue light emitted toothbrushes (LETBs) (405 nm), II group was control one and included the volunteers, who treated by standard manual toothbrushes. Clinical evaluation of changes in gingivitis compared with the baseline was visually assessed using five standard dental indices.
In the both groups there were improvement in gingivitis associated with improvement of indices of plaque, gingival bleeding and inflammation. However, in the first group addition improvement of studied indices was clearly seen which was considered as caused by anti-microbial action of blue light on gum tissue. The use of LETB has a multifactor therapeutic action on oral pathological microflora: mechanical removal of the bacteria and suppressing action on microorganisms due to photodynamic reaction.
