What is the minimum gingival clearance needed?

0.5mm
1mm
0.75mm
0.25mm

The correct answer is: 0.5mm

The minimum gingival clearance needed refers to the space between the top of a dental restoration and the gumline. This space is necessary to prevent irritation and inflammation of the gums. A clearance of 0.5mm is considered the safest and most effective, as it allows for proper oral hygiene and prevents any potential damage to the gums. This is why options B, C, and D are incorrect as they are either too small or too large, which can lead to issues such as plaque accumulation, gingival overgrowth, or damage to the tooth structure. So, a minimum clearance of 0.5mm is the recommended standard for maintaining healthy gums and overall dental health.
