Why are talon cusps considered pronic to caries?

• A. They lack a protective enamel layer
• B. They have pits which can accumulate plaque
• C. They are more sensitive to temperature changes
• D. They are softer than regular enamel

Answer: (B)

Talon cusps are considered prone to caries primarily because they often have pits or grooves that can retain plaque and food particles. These structural features create niches where bacteria can thrive, leading to an increased risk of dental caries. The rougher surface and unique morphology of talon cusps can hinder effective cleaning, making it easier for biofilm to accumulate.

Additionally, the grooves or pits are often located in areas that are challenging for patients to keep clean, especially in children who may not have perfected their oral hygiene habits. This retention of plaque contributes significantly to the likelihood of caries development in these areas, highlighting the importance of diligent oral hygiene and regular dental check-ups for patients with talon cusps.
