**Introduction**

Clinical Attachment Loss (CAL) is a crucial measurement in dentistry that helps assess the loss of attachment between the tooth and the surrounding tissues. It is calculated by subtracting the Gingival Margin (GM) level from the Probing Depth (PD). To simplify this calculation, we can create a Clinical Attachment Loss Calculator using HTML and JavaScript. In this article, we’ll provide you with the code to build this calculator, along with explanations and examples for its usage.

**How to Use**

To use the Clinical Attachment Loss Calculator, follow these simple steps:

- Enter the Probing Depth (PD) in millimeters.
- Enter the Gingival Margin (GM) level in millimeters.
- Click the “Calculate” button to get the Clinical Attachment Loss (CAL) in millimeters.

This user-friendly tool will allow dental professionals to quickly determine the Clinical Attachment Loss, an essential parameter for assessing periodontal health.

**Formula**

The formula for calculating Clinical Attachment Loss (CAL) is as follows:

Where:

**CAL**: Clinical Attachment Loss in millimeters.**PD**: Probing Depth in millimeters.**GM**: Gingival Margin level in millimeters.

**Example**

Let’s consider an example to understand how to use the Clinical Attachment Loss Calculator:

- Probing Depth (PD) = 5 mm
- Gingival Margin (GM) = 2 mm

Using the formula:

So, in this case, the Clinical Attachment Loss is 3 mm.

**FAQs**

**Q1: What is Clinical Attachment Loss (CAL)?**

**A1:** Clinical Attachment Loss (CAL) measures the loss of attachment between a tooth and the surrounding tissues, an essential parameter in periodontal health assessment.

**Q2: Why is CAL important?**

**Q3: Can I use this calculator for educational purposes?**

**A3:** Yes, this calculator is designed to assist dental professionals and students in understanding and calculating Clinical Attachment Loss.

**Conclusion**

The Clinical Attachment Loss Calculator is a valuable tool for dental professionals and students alike. It simplifies the calculation of Clinical Attachment Loss, an important parameter for evaluating periodontal health. By entering Probing Depth and Gingival Margin measurements, you can quickly determine the Clinical Attachment Loss with the click of a button. This handy calculator streamlines the process, making it easier to assess and monitor periodontal conditions.
