The significance of Candida albicans in the development of denture sto
matitis (DS), as well as the clinical and microbiological efficacy of
treatment with fluconazole and itraconazole was studied in 115 patient
s affected with DS and 200 controls (100 healthy patients with dental
prosthesis and 100 healthy patients without prosthesis). Specimens wer
e taken from all patients; subsequently all patients with positive cul
ture of the DS group were treated with fluconazole. A second specimen
was taken after 15 days of treatment with fluconazole, and if the resu
lts were positive again, treatment with itraconazole was instituted an
d the patients were given appointments for taking a third specimen. Th
e incidence of C. albicans was 92% in the group of patients with DS. A
fter treatment with fluconazole, a clinical cure of 97% and a microbio
logical cure of 78% was obtained in the patients with DS. In 3.2% of t
he cases strains resistant to fluconazole were found. The cases of mic
robiological resistance to fluconazole were treated with itraconazole
resulting in a clinical cure of 100% and a microbiological cure of 77%
. The results show the poor correlation of the clinico-microbiological
response after treatment with these antifungal agents in denture stom
atitis.
