Resumo
One of the major medical problems facing mankind in the next
century will be the resistance of many pathogenic microbes to
existing antibiotics. Oral bacteria can easily reach other body sites
and also spread to other individuals. Therefore, antibiotic-resistant
oral bacteria have the opportunity for rapid dissemination through
the community and to transfer their resistance genes to other bacterial
species. Photodynamic therapy involves the use of light-activated
drugs which may offer an alternative approach to the use of
traditional antimicrobial agents. The purpose of this study was to
evaluate bacterial reduction in infected root canal. Thirty teeth
with their root canals prepared were contaminated with
Enterococcus faecalis. Control group was untreated. Chemical
group was treated with sodium hypochlorite for 30 minutes and in
the laser group, a photosensitizer paste was placed and maintained
in the root canals for 5 minutes and irradiated with a diode laser,
output power 10 mW and l= 685nm for 3 minutes. The bacterial
reduction was significantly higher for laser group when compared to chemical and control groups. These results indicate photodynamic
therapy as an effective method to kill E. faecalis.
