Antibacterial Effect of a Temporary Cement-Dissolving Liquid.

Area of Science:

• Dental materials science
• Prosthodontics
• Microbiology

Background:

• Temporary cements are crucial in prosthodontic treatment.
• Effective removal of temporary cement is essential for prosthetic success.
• Antibacterial properties during cement removal could enhance treatment prognosis.

Purpose of the Study:

• To evaluate the antibacterial efficacy of different temporary cement removal methods.
• To compare the effectiveness of a dissolver (Temp-off), mechanical removal, and sandblasting.
• To assess the impact of cement type (eugenol-containing vs. non-eugenol) and thickness on removal efficacy.

Main Methods:

• Three removal techniques were tested: immersion in Temp-off, mechanical removal with a dental explorer, and sandblasting.
• Two temporary cements, Temp-Bond (with eugenol) and Temp-Bond NE (without eugenol), were used.
• Cements were applied at two thicknesses: 100 μm and 250 μm.

Main Results:

• Immersion in Temp-off significantly decreased bacterial counts more than other methods (P < .05).
• No significant difference in antibacterial effect was observed between Temp-Bond and Temp-Bond NE.
• A more pronounced bacterial count reduction was noted with the thicker (250 μm) cement layer.

Conclusions:

• Temp-off dissolving liquid demonstrates significant antibacterial properties during temporary cement removal.
• The non-mechanical cleaning action of Temp-off contributes to its effectiveness.
• Utilizing Temp-off for temporary cement removal may improve prosthetic treatment outcomes due to its antibacterial capabilities.
