The index used to record the plaque score is
**Core Concept**
The plaque score is a measure used in periodontology to assess the severity of periodontal disease, specifically the accumulation of plaque on the teeth. It is an important tool for clinicians to evaluate the effectiveness of treatment and monitor the progression of the disease.
**Why the Correct Answer is Right**
The correct answer is the Silness-Loe plaque index, which is a widely used method for recording the presence and severity of plaque on the teeth. This index assesses the presence of plaque on six surfaces of each tooth, and scores are assigned based on the extent of plaque coverage. The Silness-Loe plaque index is a reliable and reproducible method for evaluating plaque accumulation, and it has been widely adopted in clinical practice.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify a widely recognized or established plaque index.
**Option B:** This option is incorrect because it does not accurately describe a commonly used plaque scoring method.
**Option C:** This option is incorrect because it is not a recognized or established plaque index.
**Clinical Pearl / High-Yield Fact**
The Silness-Loe plaque index is a simple and effective method for recording plaque scores, but it requires careful training and calibration to ensure accurate and reproducible results.
**Correct Answer: D. Silness-Loe plaque index.**
