BIOLOGICAL RISKS OF RESIN-BASED MATERIALS TO THE DENTIN-PULP COMPLEX.

Area of Science:

• Restorative Dentistry
• Biomaterials Science
• Dental Public Health

Background:

• Restorative dentistry has advanced significantly due to new resin-based materials enabling tooth bonding.
• These advancements have introduced controversies regarding the biological safety of materials and techniques.
• Patient priorities have also shifted, influencing the adoption of new dental procedures.

Purpose of the Study:

• To review recent information on biological risks and consequences of resin-tooth bonding.
• To analyze how material properties and clinical manipulation influence these risks.
• To categorize biological risks into direct (toxicological) and indirect (microbiological leakage) factors.

Main Methods:

• Literature review of recent scientific publications.
• Analysis of toxicological data for resin-based dental materials.
• Examination of studies on microleakage and secondary caries in resin-bonded restorations.
• Synthesis of information on the interaction between material properties, clinical handling, and biological outcomes.

Main Results:

• Biological risks associated with resin-tooth bonding are complex and not fully understood.
• Direct biological risks stem from the inherent toxicological properties of the bonding materials.
• Indirect biological risks arise from microleakage at the tooth-restoration interface, potentially leading to secondary infections.
• Clinical manipulation by practitioners significantly affects the manifestation and severity of these risks.

Conclusions:

• Resin-tooth bonding presents both direct toxicological and indirect microbiological risks.
• Understanding and mitigating these risks are crucial for safe and effective restorative dentistry.
• Further research is needed to fully define and manage the biological consequences of these advanced dental materials.
