The data entry controls

Using data entry controls you can input data specific to different sites on the selected tooth. From the data entry controls, you can input probing depths, bleeding and suppuration points, gingival margins, clinical attachment levels, and mucogingival junction measurements.

You use the keypad to enter measurements with the mouse or a light pen. Click the Facial/Lingual button to switch from the facial side to the lingual side of a tooth (or vice versa).
