It is very important to study the problem of caries and gingivitis in adolescents who are beingtreated for orthodontic pathology with bracket systems.The method of combined treatmentwhich incorporates the use of medicine and laser therapy has been proved effective in cariesprevention.This research aims to study clinical aspects of the effectiveness of the combinedinfuence of the low-intensity laser"OPTODAN"with a wavelength of 0.85μm(Scientific De-velopment and Production Center*VEND",Saratov,Russia)in carries prevention.The researchalso aims to study the disinfection method of PAD with"FotoSan"("CMS Dental",Denmark,with a wavelength of 625-635 nm,where toluidine blue is used as photosensitizer molecules)combined with regular measure to prevent gingivitis in adolescents being treated for orthodonticpathology with bracket systems.This paper presents the results of 1.5 years of clinical study of 60i2-13-year-old children.They were examined before and after the orthodontic treatment:theirdecayed,missing,flle teeth(DMFT),decayed,missing,flle tooth surfaces(DMFS)index andhygiene status(OHI-S)were calculated,gum inflammations were detected.Before the ortho-dontic treatment,their mouths were sanitized.After orthodontic appliances were placed,thechildren were randomly divided into two groups of 30 each.Children of the first group,whilebeing treated with braces,took traditional preventative measures against gum inflammation andcaries:occupational hygiene,local antiseptics(0.05%chlorhexidine solution),the use of remi.neralizing and phosphorus containing applications four times a year.The children of the secondgroup,along with the traditional scheme of preventive measures,were treated with the devices"FotoSan"and*Optodan".Results of clinical examination of the second group have accuratelyproved decrease in the growth of dental caries intensity and surface caries intensity(ADMFT,ADMFS)and in gingivitis level at the end of the orthodontic treatment.So the results of ourclinical research have proved the efectivenesof laser therapy and comprehensive prevention ofcaries and gingivitis in adolescents using bracket system.
