Abstract
30 dentures selected for the study were disinfected using effervescent denture tablets.
Then the dentures were trimmed 1.5mm from fitting surface and relined with NBR soft
lining material. Sample was scraped from denture fitting surface after one month and
two months duration and the changes in colony forming units per mm after each month's
time were measured and marked. After one month's duration, 24 samples were reported
sterile and 6 showed colonies of Candida albicans & Staphylococcus aureus. After 2
months duration, 28 out of 30 samples became positive with C. albicans & S. aureus
colonies and aerobic spore bearing units. NBR soft liner material was sterile till
one month of clinical usage so it can be prescribed as a safe soft lining material
till one month of clinical usage in a controlled environment of oral hygiene
