Abstract

Introduction-Gingivitis is a common disease in children and can be considered a risk factor for the occurrence and progression of diseases of the parodontal tissues.

The aim of this study was to investigate the effect of low level laser therapy on gingival inflammation in children.

Material and methods–The study enrolled 100 children divided into two groups:group I (50 children with chronic catarrhal gingivitis in whom basic therapy was applied); group II (50 children with chronic catarrhal gingivitis in whom in addition to basic therapy low level laser treatment was used). Basic therapy was applied for five consecutive days in order to remove supra- and subgingival bacterial deposites. Also during this period, low level laser therapy was applied with a Scorpion-Dental-Optima apparatus (wavelength 635nm, starting strength 25mV, exposure time 120s). The following indices were measured before therapy, after 1st and 5th treatment using Muhlemann bleeding index (PBI).

Results–There was no difference in mean PBI values between investigated groups before therapy. Results showed that mean PBI values were statistically significantly lower in I group compared to II group after the 1st and 5th treatment.

Conclusion-Using clinical parameter, we established that gingivitis can be successfully treated with basic therapy. Low level laser use can markedly improve this effect.
