Question

What is the recommended working force applied when using a CPITN probe?

• A. Less than 20 grams
• B. Less than 10 grams
• C. Less than 5 grams
• D. Less than 15 grams

Hint:

CPITN probe force should be light — approximately 20 grams (similar to the force needed to blanch the fingernail).

Answer 1

The Correct Option is A

The question asks about the recommended working force to be applied when using a CPITN (Community Periodontal Index of Treatment Needs) probe. This probe is used in dentistry to measure the periodontal status of a patient's gums.

Explanation:

1. The CPITN probe is a periodontal probe with a ball-point end, which is marked to help measure pocket depths and identify the presence of calculus and other periodontal diseases.

2. It is designed to provide a standardized method for periodontal examination and is utilized extensively in public health dentistry for screening and monitoring periodontal diseases.

3. The recommended working force when using the CPITN probe is crucial. Applying too much force can cause discomfort to the patient or give inaccurate readings.

4. The recommended force is less than 20 grams to ensure safe and effective probing without damaging the tissues.

Options Analysis:

• Less than 20 grams - This is the correct answer. It ensures that the probing process is gentle and accurate.
• Less than 10 grams - While gentle probing is necessary, less than 10 grams may not provide the necessary tactile feedback to identify periodontal problems accurately.
• Less than 5 grams - This force is too low for effective probing, which could lead to oversight of periodontal issues.
• Less than 15 grams - Although it is a feasible force for probing, the standard recommendation is less than 20 grams, providing a little more margin for effective probing.

Therefore, the correct option is Less than 20 grams.

Conclusion:

The CPITN probe should be used with a force of less than 20 grams for accurate and safe examination during periodontal assessments.
