Summary

Glass-ionomer cement and citric acid cavity cleaning significantly reduced artificial caries lesion depth. Fluoride-releasing materials also helped minimize demineralization around dental restorations.

Area of Science:

  • Restorative Dentistry
  • Cariology
  • Dental Materials Science

Background:

  • Dental caries remains a significant oral health challenge, necessitating effective restorative materials and techniques.
  • Understanding microleakage and demineralization around restorations is crucial for long-term clinical success.
  • Artificial caries models provide a controlled environment to study lesion progression and prevention strategies.

Purpose of the Study:

  • To evaluate the effectiveness of different cavity cleaning regimes and restorative materials in preventing artificial caries-like lesions.
  • To compare the impact of dentin bonding agents and glass-ionomer cement on demineralization adjacent to restorations.
  • To assess microleakage and lesion depth using polarized light microscopy and microradiography.

Main Methods:

  • Artificial caries lesions were induced in extracted teeth adjacent to microfilled resin (with/without dentin bonding agent) and glass-ionomer cement restorations.
  • Cavity cleaning methods included water spray, 50% citric acid, and a proprietary cleaner.
  • Lesion depth and zonal patterns were analyzed using polarized light microscopy and microradiography.

Main Results:

  • Cavity cleaning with citric acid or the proprietary cleaner, and the use of fluoride-releasing materials, reduced lesion depths.
  • Glass-ionomer cement in citric acid-cleaned cavities exhibited significantly shallower lesions compared to other groups.
  • Dentin bonding agents did not influence demineralization depth around microfilled resin restorations.

Conclusions:

  • Citric acid and proprietary cleaners, along with fluoride-releasing materials like glass-ionomer cement, are effective in reducing artificial caries progression.
  • Glass-ionomer cement shows superior performance in minimizing lesion depth, particularly when combined with acidic cavity cleaning, despite its solubility.
  • Dentin bonding agents do not offer additional protection against demineralization in this artificial caries model.
