Study Notes
Intended Learning Outcomes
- Students should be able to revise steps for a good clinical periodontal session
- Explain the rationale for a fulcrum
- Recognize and demonstrate intra-oral and extra-oral fulcrums
- Identify and demonstrate appropriate working ends using the lower terminal shank
- Explain the appropriate usage and situation for different instrumentation motions
- Demonstrate usage of instrumentation motions
Recap
- Diagrams show healthy teeth with intact enamel and supragingival, subgingival biofilms and homeostatic inflammation.
- Diagrams display various angles and application points, including elbow, knee, head of fibula to floor.
Instruments
- Images of various dental instruments are presented.
Stability & Safety
- Key elements for stability & safety include a fulcrum and finger rests
- Intra-oral and extra-oral fulcrums are described
Fulcrum
- A fulcrum supports your hand and provides safety for both you and the patient
- It allows hand movement and precise movements.
Finger Rests
- The document questions what features are ideal for a finger rest, and also what is the ideal structure for a finger rest.
Intra-oral Fulcrum
- Used to stabilize the clinician's dominant hand inside the mouth
- Use a pad of the ring finger near the tooth being instrumented.
- This decreases likelihood of injury for both patient and clinician.
- Focus on the incisal edge or occlusal surface, and occlusobuccal or occluso-lingual angles of a stable tooth.
Extra-oral Fulcrum
- Stabilizes the clinician's dominant and non-dominant hands outside the mouth.
- Commonly used on the cheek or chin.
- Students should consider potential risks.
Which End Do I Use?
- This section discusses the use of instruments.
- The cyclic process between Instrument action, Ergonomics, Detection and Grip is visible in a circular diagram.
Lower Terminal Shank
- The bent section of the shank closest to the working end is described
- Placement of the lower terminal shank is parallel with the midline plane
- Covering the whole tooth surface, atraumatic, and use of the correct aspect of the instrument are stressed.
Starting Position
- Use the lower terminal shank parallel with midline plane.
- Ensure to cover the whole tooth surface, avoiding trauma.
- Correct instrument aspect should be used.
Start Midpoint—The Move But Look Closer
- Visual aids illustrating the midpoint of movement are provided.
Which End Do I Use?
- The document displays visual examples, illustrating the correct end for the instrument's use for treatment.
Motion
- Four components (pivot) of the motion are diagrammed.
- Wrist motion activation, digital motion activation, and handle roll are included in the illustration.
Digital Motion Activation
- Explains when and why digital motion activation is used.
- Visual aids depict the procedure.
Wrist Motion Activation
- Discusses when and why wrist motion activation should be used.
- Visual aids are presented to illustrate the procedure.
Handle Roll
- When and why handle roll motion activation is conducted is discussed
- Depicted visually, the procedure is illustrated.
Look Closely and Piece It Together
- This section illustrates how to visualize and conceptualize the process more completely.
- It shows how parts relate to the whole.
