Dentin Cleaning Ability of an Amazon Bioactive: Evaluation by Scanning Electron Microscopy

Area of Science:

• Biomaterials Science
• Dental Materials
• Microbiology

Background:

• Effective dentin cleaning is crucial for dental restoration success, preventing debris accumulation and microbial contamination.
• Traditional cleaning methods may have limitations in debris removal and antimicrobial efficacy.

Purpose of the Study:

• To evaluate the efficacy of copaiba oil emulsions (CO) and ethanol extract of propolis (EP) in cleaning dentin surfaces.
• To compare the morphological changes on dentin surfaces treated with CO and EP against conventional methods using scanning electron microscopy (SEM).

Main Methods:

• Twenty-four pre-molar teeth were sectioned into dentin discs and divided into eight experimental groups.
• Treatments included no cleaning, air/water spray, varying concentrations of CO (10% and 30%), CO with additive (A), 1% EP, and 2% Chlorhexidine.
• Scanning electron microscopy (SEM) was used to analyze dentin surface morphology, debris, and microorganism presence.

Main Results:

• Control groups (no cleaning, air/water spray, 1% EP) exhibited significant debris and numerous microorganisms.
• Groups treated with 10% and 30% copaiba oil emulsions (with or without additive) and 2% Chlorhexidine showed substantially reduced debris (0-50 particles) and countable microorganisms (50-100 colonies).
• Copaiba oil emulsions and propolis extract demonstrated superior cleaning compared to air/water spray and untreated controls.

Conclusions:

• Copaiba oil emulsions and ethanol extract of propolis exhibit significant potential as bioactive dental cleaning agents.
• These natural compounds effectively reduce dentin debris and microbial load, suggesting feasibility for clinical application in dentistry.
