Aim and objective: The purpose of this study was to compare the dimensional stability of heat cured acrylic denture base resin before and after disinfecting with different disinfectants. Materials and methods: Seventy heat cured acrylic samples were made from a preformed stainless steel metal die of dimensions 65×10×3 mm. The linear dimensions were measured before and after immersion (24 hours) in six different disinfectants with an electronic digital vernier caliper. The data was analyzed statistically using paired t-test and one-way ANOVA, Dunnette T-test. Results: It was found that the heat cure acrylic samples did not produce any statistical changes (p > 0.05) in their linear dimension, upon immersion in six different disinfectant solutions. Conclusion: It was found that all the disinfectants showed some amount of linear changes, but statistically insignificant (p > 0.05). Therefore, the present study strongly recommends standard disinfection protocol for all removable oral prosthesis used intra-orally to combat virulent microorganisms. Clinical significance: Acrylic resins are most widely used for denture prosthesis for patients with missing teeth. Procedures like adjustment and denture repair produce fine particles that can be hazardous to the dental professional. It is very important to disinfect the denture to prevent cross-contamination against virulent pathogens to avoid air-borne infections. So it is necessary to know the physical changes in acrylic resin caused due to immersion in potent biocidal agents. Owing to the porous nature of denture base resin there is inherent property to absorb water and likely to undergo dimensional changes.
