Purpose: The purpose of this study was to investigate the effect of simulated gastric fluid on the

surface hardness of different provisional prosthetic materials.

Materials and Methods: A total of fourty-eight specimens (Acrytemp, Protemp 4, Temdent Classic

Dark, Bisco Temp S) were prepared using a PTFE mould. After polishing, the specimens were

immersed simulated gastric fluid for 24 hours. Surface hardness was measured using a Vickers

hardness tester. Surface hardness measurements was carried out before and after the specimens

immersed in simulated gastric fluid. Data were analyzed using the statistical software and

subjected to one-way ANOVA and a post hoc Tukey test were used for multiple comparisons

( =0.05).

Results: The results of revealed that the simulated gastric fluid effects the hardness of provisional

prosthetic materials. There were statistically significant differences in values of hardness of

prosthetic materials (P<.001).

Conclusions: Based on the results of the study, the hardness of provisional prosthetic materials

were affected by simulated gastric fluid. The patients with gastroesophageal reflux disease should

be warned by the dentists about the strength of the provisional prosthetic materials
