Furcation Probe

Precision Tool for Root Involvement Detection

Detecting Furcation Involvement with WeCare Surgical Dental Nabers Probe Insturment

A furcation defect refers to bone loss that occurs where the roots of a multirooted tooth divide — most commonly in molars and upper premolars.

This condition often develops as a result of periodontal disease, leading to tooth instability, plaque accumulation, and difficulty in maintaining oral hygiene.

Early detection of furcation defects is crucial for preventing tooth loss and guiding effective periodontal treatment.

At WeCare Surgical, our Nabers Probes are manufactured with surgical-grade AISI 420 stainless steel, offering exceptional accuracy, durability, and tactile sensitivity — trusted by periodontists and hygienists worldwide.

What Is a Furcation Probe?

A Furcation Probe, also known as a Nabers Probe, is a specialized periodontal instrument used to detect and measure furcation involvement — the bone loss between the roots of teeth.
It allows clinicians to determine the extent and severity of bone loss and plan treatment with precision.

Clinical Use and Application

Furcation probes are essential diagnostic tools used in:

  • Identifying furcation involvement along with radiographs and CBCT scans

  • Treatment planning in root resection, scaling, and regenerative procedures

  • Monitoring outcomes of periodontal therapy

By integrating furcation measurements with clinical findings, WeCare Surgical Probes ensure precision and confidence in every periodontal assessment.

Product Highlights

How the Furcation Probe Is Used

The Nabers Probe is used by dental professionals to measure both horizontal and vertical bone loss in furcation areas — the spaces between the roots of multi-rooted teeth.

It is primarily applied in:

  • Molars and upper premolars (teeth with multiple roots)

  • Clinical assessments of bone loss and periodontal pocket depth

Laser-engraved millimeter markings ensure consistent and reliable readings, enabling clinicians to classify furcation involvement accurately using Glickman or Hamp classification systems.

Furcation Involvement Classifications (Simplified)

Glickman Classification (1953)

Class I

The concavity, just above the furcation entrance, on the root trunk can be felt with the probe tip; however, the furcation probe cannot enter the furcation area.

Glickman Classification (1953) Class I
Glickman Classification (1953) Class II

Class II

The probe is able to partially enter the furcation, extending approximately one third of the width of the tooth, but it is not able to pass completely through the furcation.

Class II

The probe is able to partially enter the furcation, extending approximately one third of the width of the tooth, but it is not able to pass completely through the furcation.

Glickman Classification (1953) Class II

Class III

In mandibular molars, the probe passes completely through the furcation between the mesial and distal roots.
In maxillary molars, the probe passes between the mesiobuccal and distobuccal roots and touches the palatal root.

Glickman Classification (1953) Class III
Glickman Classification (1953) Class IV

Class IV

Same as a class III furcation involvement except that the entrance to the furcation is visible clinically owing to tissue recession.

Class IV

Same as a class III furcation involvement except that the entrance to the furcation is visible clinically owing to tissue recession.

Glickman Classification (1953) Class IV

Hamp Classification (1975)

Class I

This stage shows mild horizontal bone loss of less than 3 mm. The defect is limited and does not pass through the bone. Clinically, it appears as an early furcation involvement with minimal tissue damage. Early treatment can usually stop further progression.

Hamp Classification (1975) Class I
Hamp Classification (1975) Class II

Class II

Here, bone loss is greater than 3 mm but not through-and-through. The furcation defect is partially advanced, with some bone still intact. It indicates moderate periodontal involvement. Surgical care and good maintenance are often needed to control the disease.

 

Class II

Here, bone loss is greater than 3 mm but not through-and-through. The furcation defect is partially advanced, with some bone still intact. It indicates moderate periodontal involvement. Surgical care and good maintenance are often needed to control the disease.

 

Hamp Classification (1975) Class II

Class III

This class shows complete through-and-through bone loss between the roots. The furcation is fully open from one side to the other. It reflects severe periodontal destruction and loss of attachment. Treatment usually requires advanced surgical procedures.
