Study Notes

Probing Pressure

Probing pressure should be between 15 and 25 grams to obtain an accurate reading.
A pressure of greater than 25 grams can cause trauma and perforate the epithelium.
Probing pressure should be atraumatic.
When probing, it is important to consider the context of the patient and their comfort level.

Factors Affecting Probing Accuracy

Preparation: Create a mind map with factors that impact probing accuracy.
Justification: All comments about factors should be justified with evidence.
References: Make note of the references on this subject.

Tactile Sensation Activity

Identify different features on teeth, restorations, and anomalies.
Notice differences in sensations, noises, and how to enhance identification.

Normal Conditions

The probe should move smoothly from the junctional epithelium to the gingival margin without any interruptions.
The probe feels a gritty sensation as it passes over fine granular deposits.

Adaptation and Positioning of the Probe

The probe tip should be kept in contact with the tooth surface.
The probe tip should not be held away from the tooth surface.
The probe should follow the shape of the tooth, such as the bulbosity, line angles, and tooth planes.

Parallelism During Probing

The probe should be parallel to the long axis of the tooth.
If the probe is not parallel to the long axis of the tooth, inaccurate readings will be obtained.

Interproximal Probing

Ensure the probe is at the highest point of disease.
The probe should be positioned using an occlusal and proximal view.

Interproximal Probing Technique

The angle of the probe depends on the tooth and may be between 25 and 45 degrees.
The probe tip should be in the interproximal window.

Different Angles During Probing

Correct Angulation: The probe is correctly angled.
Under-Angling: The probe is angled too shallowly.
Over-Angling: The probe is angled too deeply.

Probing Walking Stroke

The probe tip should be in contact with the tooth surface during the probing walking stroke.
The probe should be walked along the junctional epithelium, adapting for live angles.

Purpose of the Probing Walking Stroke

Detect calculus and spicules.
Ensure the probe tip does not jump and miss any areas.

Limitations of Probing

Detail: Probing provides limited details.
Inaccuracies: Probing can be inaccurate.
Time: Probing takes time.
Patient Tolerance: Probing can be uncomfortable for the patient.
Operator Variation: Different operators may use varying pressure and technique.
Subjective: Interpretation of readings can be subjective.

Advantages of Probing

Cheap: Probing is a low-cost method.
Quick: Probing is a quick method.
Reproducible to an extent: Probing can be reproduced to a certain degree.
Accessible: Probing is widely accessible.

Clinician’s Need to Be Reflective

It is important for clinicians to be reflective about their probing technique to ensure accuracy.

Subgingival Calculus

The probe will move out and around a raised bump of calculus before returning to the tooth surface.

Restoration with Overhang Margin

The probe path is blocked by the overhang and must move away from the tooth surface.

Restoration with Deficient Margin

The probe will pass over the restoration and dip into the surface.

Carious Lesion

The probe will dip into the lesion and come out again as it moves along the tooth surface.
Soft lesions feel sticky and can cause the probe to become stuck.
