What is the recommended initial positioning when probing maxillary molars?

• A. Position the probe to the side of the patient's face
• B. Position the probe behind the patient
• C. Use a long handle
• D. Place the probe on the cheek

Answer: (C)

Access to the back teeth can be tricky, so starting with a long-handled periodontal probe is best. The extra length lets you reach the posterior maxillary molars comfortably and lets the tip stay aligned with the long axis of the tooth, giving you a stable, parallel path into the sulcus. This improves accuracy and reduces the need to bend the wrist, while also keeping the probe away from the patient’s cheek or lip.

Other positions would make accessing the molars awkward or unsafe: placing the probe on the cheek or behind the patient disrupts the angle and control, and positioning the probe to the side of the face doesn’t provide the reach needed for reliable measurements.
