AIM: This study aimed to verify the influence of oral environment and
denture cleansers on the surface roughness and hardness of two different
denture base materials.
METHODS: A total of sixteen identical removable disc specimens (RDS)
were processed. Eight RDS were made from heat-cured acrylic resin (AR) and
the other eight were fabricated from thermoplastic injection moulded resin (TR).
Surface roughness and hardness of DRS were measured using ultrasonic
profilometry and Universal testing machine respectively. Then the four RDS
(two AR and two of TR) were fixed to each maxillary denture, after three
months RDS were retrieved. Surface roughness and hardness of RDS have
measured again.
RESULTS: The surface roughness measurements revealed no significant
difference (p >0.05) for both disc groups at baseline. However, both groups
showed a significant increase in the surface roughness after three months
with higher mean value for (TR) group. On the other hand, the (AR) group
showed higher hardness mean value than (TR) group at baseline with no
significant decrease in the hardness values (p >0.05) following three months
follow-up period.
CONCLUSIONS: Denture cleansers have an effect on the denture’s
surface roughness and hardness concurrently with an oral condition which
will consequently influence the complete dentures’ lifetime and patients’
satisfaction.
