The Mirror fulcrum is position on hard or soft tissue for tooth #12-DF around tooth number: (10/11 for a right-handed operator or 3:00 for a left-handed operator). The operator could select either the 13/14 curet or the 204S to remove the calculus on #12-DF supra.

The more posterior the tooth, the more angulated a shank must be. The mesial surface of a molar is less accessible than the distal surface.

The 17/23 explorer is used to detect carious lesions and defective margins of restorations. The 11/12 explorer is the preferred instrument of choice for calculus detection.

The modified pen grasp for the mirror helps the clinician provide stability and control. The clinician can use a rubber band and/or a ball to strengthen the muscles of the hand and to reduce operator fatigue.

The lower shank is closest to the handle.

The universal curet is used on all surfaces of the maxillary and mandibular teeth. The 11/12 curet is used on the mesial, buccal and distal surfaces.

Tactile sensitivity is defined as:

Answer the question based on your dominant hand. The operator chair position for tooth #3 facial is at (9:00 for a right-handed operator) or (1-2:00 for a left-handed operator). The instrument of choice to remove calculus on the lingual surface of tooth #3 could be the 7/8 or 11/12 curet?

The mouth mirror can become fogged during the examination of the tooth surfaces. The clinician can prevent condensation on the mirror face by requesting the patient to breathe through their nose and/or rub the surface of the mirror along the buccal mucosa to coat the mirror with saliva.
