Summary: | When they are used to treat inflamed, irritated, or distorted tissues
or in implant therapy, tissue conditioners are required to function
over relatively long time periods. Purpose: This in vitro study
evaluated the effect of sealer and water storage on permanent
deformation one tissue conditioner. Material and methods: Sixty
cylindrically-shaped specimens (12.7-mm diameter 3 19.0-mm
height) were used for the deformation tests. Specimens were
divided into 6 test groups (n=10), according to surface treatment
(sealer application) and water storage (1 hour, 1 week and 2
weeks). Permanent deformation, expressed as a percent (%), was
determined using ADA specification no. 18. Data were examined a
analysis of variance and a Mann-Whitney test (α= 0.05). Results:
Significant differences were observed only after 1 week of water
storage, for both groups. The surface treated group presented the
highest permanent deformation percentage. Conclusions: This in
vitro study indicated that the tissue conditioner evaluated is only
useful for 1 week. After this period, the material must be replaced. |
