What size condenser tip should fit passively into the cavity?

• A. 1.5 mm
• B. 1.0 mm
• C. 0.5 mm
• D. 2.0 mm

Answer: (B)

Condenser tips should be sized so they can sit into the prepared cavity with no binding. A tip that fits passively means you can place it into the cavity and seat it gently, without having to force it through walls or margins. This allows the condensation force to be transmitted evenly to all parts of the prep, helping to adapt the amalgam to floors and walls and to minimize voids. If the tip is too large, it will bind or wedge at the margins, risking damage to the tooth or overpreparation. If it’s too small, it won’t adequately condense the material, which can leave porosities and poor contact. The standard, passively fitting size is the small, conventional tip that can glide in smoothly, providing consistent condensation without forcing the cavity walls.
