Summary
Approximal finishing strips can damage enamel and restorations. Careful selection of these dental tools is crucial for optimal restoration quality and patient outcomes.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
- Biomaterials
Background:
- Approximal finishing strips are commonly used in dental restorations.
- Their impact on restoration quality and adjacent tooth structure requires thorough evaluation.
Purpose of the Study:
- To assess the effects of approximal finishing strips on restoration surfaces, margins, and adjacent enamel.
- To provide guidelines for selecting appropriate finishing strips in clinical practice.
Main Methods:
- Scanning electron microscopy (SEM) was employed to examine the surfaces of restorations, their margins, and adjacent enamel.
- A representative sample of approximal finishing strips was investigated.
Main Results:
- The evaluated finishing strips demonstrated a tendency to damage enamel surfaces.
- Restorations exhibited suboptimal surface finish and marginal adaptation after treatment.
- Inconsistent results were observed regarding the effectiveness of the tested strips.
Conclusions:
- The use of certain approximal finishing strips can negatively affect enamel and restoration integrity.
- Clinical guidelines are proposed to aid in the judicious selection of these instruments for improved restorative outcomes.
