Which surfaces can be accessed from the 10 O' clock position?

Accessing tooth surfaces from the 10 o'clock position is primarily suited for working on the posterior teeth that are positioned away from the clinician's body. This position allows the dental hygienist to effectively visualize and reach the buccal and lingual surfaces of the posterior teeth, as well as the occlusal surfaces of these teeth, particularly on the patient’s left side.

When working in the 10 o'clock position, the clinician has an optimal angle to maneuver instruments and provide thorough care without obstruction, making it ideal for accessing the posterior teeth that are away from them. This position facilitates a comfortable working posture and allows for better access to otherwise challenging areas.

In contrast, when attempting to access maxillary anterior teeth or mandibular anterior teeth towards the clinician from the 10 o'clock position, it may limit visibility and accessibility. The best positions for accessing those areas would typically be more frontal rather than from the side. Therefore, while there may be some limited access to the anterior surfaces, the primary focus for the 10 o'clock position is indeed on the posterior teeth that are positioned away from the clinician.
