What is the purpose of a plaque index?

The purpose of a plaque index is primarily to evaluate the amount of dental plaque present on a patient's teeth, which directly relates to their oral hygiene practices. The measure obtained from a plaque index can offer insights into the patient's proficiency in maintaining good oral hygiene. By scoring the plaque index, dental professionals can identify areas where a patient may be struggling to keep teeth clean and can provide targeted education or intervention to improve those specific areas.

The use of a plaque index helps in tracking changes over time, allowing health care providers to assess the effectiveness of oral care routines and possibly motivate patients to enhance their oral hygiene behaviors. Thus, it serves an integral role in promoting oral health and preventing periodontal disease, making it a key tool in dental assessments.
