periodontal probes


There are several other types of dental probes used by dental professionals for various purposes. Some of the commonly used probes include:

1. Williams Probe: The Williams probe is a traditional periodontal probe with a blunt, ball-ended tip. It is often used to measure pocket depth and assess periodontal health.

2. Nabers Probe: The Nabers probe is a specialized periodontal probe used to assess the stability and support of endodontically treated teeth.

3. Marquis Probe: The Marquis probe is designed for assessing gingival health and measuring gingival recession.

4. UNC-15 Probe: The UNC-15 probe is a periodontal probe with a 1.5 mm ball-end tip used for measuring clinical attachment level (CAL) in periodontal pockets.

5. Michigan O Probe: The Michigan O probe is used to measure the width of attached gingiva and assess gingival health.

6. Periodontal Explorer (Shepherd's Hook Explorer): The periodontal explorer is a diagnostic instrument with a curved, pointed tip used to detect dental caries and calculus deposits on tooth surfaces.

7. Furcation Probe: The furcation probe is used to assess the extent of furcation involvement in multi-rooted teeth affected by periodontal disease.

8. O'Leary Probe: The O'Leary probe is designed for plaque control assessments, measuring the presence of plaque on tooth surfaces.

9. Perio-Implant Probe: This probe is specifically designed for assessing the health and measurements around dental implants.


10. Florida Probe-Explorer Combination: Some advanced systems combine periodontal probing and dental exploration features for comprehensive periodontal and restorative assessments.

These different types of probes are used based on the specific needs of the dental examination and the area being assessed. Dental professionals select the appropriate probe based on the clinical situation and the information required to make accurate diagnoses and treatment decisions.

The Florida Probe is an advanced computerized periodontal probing system used by dental professionals to accurately measure and assess periodontal health. It is a sophisticated tool that aids in the diagnosis and monitoring of periodontal conditions, providing more detailed and precise information compared to traditional manual probing methods.

Key features of the Florida Probe system include:

1. Computerized Probing: The Florida Probe system consists of a handheld probe with a disposable probe tip. The probe is connected to a computer via a USB interface. When the probe is gently inserted into the gingival sulcus or periodontal pocket, it measures and records the pocket depth electronically.

2. Automated Measurements: As the probe is inserted into the sulcus or pocket, the computer automatically records the pocket depth and displays it on the screen in real-time. The system eliminates the need for manual measurements and reduces the potential for human errors.

3. Comprehensive Data Collection: In addition to pocket depth, the Florida Probe system can record other clinical parameters, such as gingival recession, bleeding on probing, and tooth mobility. This comprehensive data collection allows for a more detailed assessment of periodontal health.

4. Perio Charting Software: The Florida Probe system comes with specialized perio charting software that stores and organizes the collected data. The software generates easy-to-read graphical representations of the periodontal conditions, making it convenient for dental professionals to review and share the findings with patients.

5. Periodontal Risk Assessment: The Florida Probe system can also assist in determining the risk of periodontal disease for individual patients. By analyzing the recorded data, the software can identify areas of concern and provide treatment recommendations based on the severity of the periodontal condition.

6. Patient Education: The visual representation of the periodontal health data generated by the Florida Probe system can be used to educate patients about their oral health status and the importance of maintaining good oral hygiene practices.

The Florida Probe system has revolutionized periodontal examinations by providing more accurate, efficient, and comprehensive data compared to traditional manual probing methods. It enables dental professionals to deliver evidence-based periodontal care and improve patient outcomes through early detection and appropriate intervention for periodontal diseases.


The CPITN (Community Periodontal Index of Treatment Needs) probe, also known as the WHO probe, is a dental instrument used by dental professionals to assess the periodontal health of an individual. It is a standardized tool developed by the World Health Organization (WHO) to provide a quick and uniform assessment of periodontal conditions in populations during epidemiological surveys.

The CPITN probe is a periodontal screening instrument that helps identify and classify periodontal conditions into specific categories based on the presence and severity of periodontal pockets, gingival bleeding, and calculus deposits. It consists of a specially designed, ball-ended probe with color-coded markings.

Here's how the CPITN probe works:

1. Ball-Ended Probe: The CPITN probe has a rounded ball tip with a diameter of 0.5 mm. The ball-ended tip allows gentle insertion into the gingival sulcus or periodontal pocket without causing trauma to the tissues.

2. Color-Coded Markings: The probe is color-coded into four segments, each representing a specific periodontal condition:

   - Green: No calculus or bleeding on probing (Healthy)
   - Yellow: Supragingival or subgingival calculus deposits without bleeding on probing (Subgingival or Supragingival Calculus)
   - Blue: Gingival bleeding detected after probing (Bleeding on Probing)
   - Red: Periodontal pocket depth of 4 mm or more (Deep Periodontal Pocket)

3. Probing Procedure: The dentist or dental hygienist gently inserts the CPITN probe into the gingival sulcus or periodontal pocket and moves it along the tooth surface to assess pocket depth and gingival bleeding. The findings are recorded based on the color-coded segments.

The CPITN probe is particularly useful for assessing periodontal health in community settings, as it provides a rapid screening method without the need for complex measurements or expensive equipment. It allows dental professionals to identify individuals with different levels of periodontal treatment needs and prioritize interventions accordingly. However, it is important to note that the CPITN probe provides a basic screening and does not replace a comprehensive periodontal examination, which may include more detailed measurements using a periodontal probe.
