Biocompatibility Of Dental Materials Practice Test

Conditions that retain plaque, such as rough surfaces or open margins, increase which response around dental materials?

Hypersensitivity Inflammatory Cytotoxic Allergic reaction

Correct Answer:

Inflammatory

Explanation:

Rough surfaces and open margins around a dental restoration trap plaque, creating a biofilm that irritates the surrounding gingival and periodontal tissues. The bacteria and their byproducts provoke the body's inflammatory response, leading to signs like redness, swelling, and bleeding on probing. This is a general, nonspecific defense to bacterial challenge, not a targeted immune reaction to a material or toxin. It’s also not about direct cell toxicity or a true allergic or hypersensitive process. So the surrounding tissue response in this plaque-filled scenario is an inflammatory reaction.
