Dental Admissions Test (DAT) 2025 – 400 Free Practice Questions to Pass the Exam

The dental plaque index is specifically designed to measure the amount of plaque present on the teeth. This assessment is crucial because dental plaque is a sticky film of bacteria that forms on the teeth and can lead to various dental issues, including cavities and gum disease if not removed through proper oral hygiene. By quantifying plaque accumulation, dental professionals can evaluate a patient's oral hygiene practices and the potential risk of developing dental diseases.

Other choices, while related to oral health, do not accurately capture the primary purpose of the dental plaque index. For instance, measuring the strength of teeth or evaluating the production of saliva pertains to different aspects of dental health. Similarly, assessing gum health involves examining the condition of the gums primarily rather than specifically the plaque buildup on teeth. Therefore, understanding the significance of plaque measurement is key to preventing dental problems and promoting overall oral health.
