Interproximal reduction involves what?

Interproximal reduction involves what?

• A. Extraction of a tooth
• B. Bonding a second archwire
• C. Occlusal adjustment
• D. Removal of enamel from interproximal surfaces to create space

Answer: (D)

Interproximal reduction is the deliberate removal of enamel from the surfaces between adjacent teeth to create space in the dental arch. This technique, often used in orthodontics, helps relieve mild to moderate crowding or adjust tooth size discrepancies without needing to extract a tooth. By thinning the enamel on the mesial or distal sides of selected teeth, a small amount of space is gained while preserving tooth structure. The procedure must be done carefully to avoid exposing dentin and to yield a smooth, plaque-resistant surface after polishing. It is distinct from extracting a tooth, which reduces the number of teeth; from bonding a second archwire, which relates to wiring and brackets; and from occlusal adjustment, which reshapes biting surfaces.
