Pre-clinical Periodontal Instrumentation: H6/7
TLDRProfessor Laura Mattingly from the University of Detroit Mercy School of Dentistry delivers a comprehensive lecture on the proper use of periodontal instruments, specifically sickle scalers, in the DPE 8111 periodontics course. The video script emphasizes the importance of understanding the instrument's design, such as the flaring direction, and adopting a modified pen grasp for effective control and rolling motion. She illustrates the technique of applying the instrument with a firm fulcrum, using controlled one to three millimeter strokes, and alternating between front-to-back and side-to-side strokes. The summary highlights the need for a neutral wrist position and ergonomics, focusing on rocking on the fulcrum rather than finger motion. The lecture also touches on the process of instrumenting the lingual aspect of mandibular teeth with precision and control.
Takeaways
- 🦾 The proper use of sickle scalers is discussed, with emphasis on the instrument's design, such as flaring to the left for right-handed tooth instrumentation.
- 🤚 Modified pen grasp technique is highlighted, where the thumb is across from the index finger, with the middle finger on the functional shank and the ring finger acting as a fulcrum.
- 👐 The importance of maintaining space between the fingers to allow for rolling movement and avoiding a tight grip that could impede instrument control is stressed.
- 📏 The technique involves applying the instrument from the midline fulcrum one to two teeth away from the starting point of the tooth being treated.
- 🔄 The concept of 'rolling' the instrument is introduced, which is a key part of the modified pen grasp technique for better adaptation to the tooth's surface.
- 📉 Emphasizing the need for a firm fulcrum to prevent slips that could lead to discomfort or injury, both for the practitioner and the patient.
- 🤲 The technique involves using controlled, short strokes (1-3 millimeters) and rocking on the fulcrum rather than bending the fingers or flexing the wrist.
- 🔄 Ergonomics are improved by rolling the thumb forward or back, rather than the entire wrist, to adapt the instrument to the tooth.
- 🚫 Avoid hyperflexion of the wrist in opposite directions, which can reduce the effectiveness of the instrument's motion.
- ✋ The forearm and wrist should remain neutral, with most of the instrumentation coming from the rocking motion on the fulcrum.
- 📍 The starting point for the stroke should be at the height of the gingival margin, ensuring precision and control in the procedure.
Q & A
Who is the speaker in the provided transcript?
-The speaker is Professor Laura Mattingly, a preclinical faculty member at the University of Detroit Mercy School of Dentistry.
What course is the speaker discussing in the transcript?
-The speaker is discussing the DPE 8111 periodontics course, specifically its clinical portion.
What is the purpose of the instrument's flaring to the left or right?
-The flaring of the instrument to the left or right indicates the side of the tooth that should be instrumented. If the instrument flares to the left, the tooth should be instrumented on the right side, and vice versa.
What is a modified pen grasp?
-A modified pen grasp is a technique where the thumb is across from the index finger, with the middle finger on the functional shank and the ring finger acting as a fulcrum on the pad of the ring finger. This allows for rolling motion and better control of the instrument.
Why is it important to maintain a firm fulcrum while using the instrument?
-A firm fulcrum prevents slipping of the instrument, which could lead to injury or discomfort for both the practitioner and the patient. It ensures precision and control during the procedure.
How should the practitioner's wrist and forearm be positioned during instrumentation?
-The practitioner's wrist and forearm should be kept in a neutral position to promote better ergonomics and prevent strain. The motion for instrumentation should come from rocking on the fulcrum rather than bending the fingers or flexing the wrist.
What is the significance of rolling the instrument during the procedure?
-Rolling the instrument helps to adapt it better to the tooth's surface, ensuring effective cleaning and reducing the risk of injury to the patient's soft tissues.
What type of strokes should be used for effective instrumentation?
-Short, controlled strokes of one to three millimeters should be used. These strokes can be side to side or front to back, depending on the tooth's surface being worked on.
Why is it recommended to start the stroke at the height of the gingival margin?
-Starting the stroke at the height of the gingival margin allows for a more precise and controlled cleaning of the tooth and gingival area, preventing damage to the surrounding tissues.
How should the practitioner move the instrument to clean the lingual aspect of the mandibular teeth?
-The practitioner should start from the midline and use a combination of side-to-side and front-to-back strokes, rolling the instrument to the interproximal area for effective cleaning.
What is the importance of maintaining the instrument handles close to parallel to the tooth?
-Maintaining the instrument handles close to parallel to the tooth helps create a cutting edge against the tooth, which is essential for effective scaling and cleaning.

🦷 Introduction to Dental Instrumentation Techniques
Professor Laura Mattingly introduces the criteria for using dental instruments, specifically focusing on sickle scalers, within the DPE 8111 periodontics course at the University of Detroit Mercy School of Dentistry. She explains the importance of the modified pen grasp technique, which involves positioning the thumb, index, middle, and ring fingers to allow for rolling motion and effective instrumentation. The professor emphasizes the need for a firm fulcrum and the correct application of the instrument to the tooth, highlighting the importance of a controlled stroke technique. She demonstrates the use of the instrument on a model tooth, detailing the front-to-back and side-to-side strokes, and the importance of maintaining a neutral wrist and forearm position for better ergonomics and precise control.
📚 Advanced Instrumentation Techniques and Ergonomics
The second paragraph delves into more advanced aspects of dental instrumentation, focusing on the ergonomics and precise motion required for effective scaling. Professor Mattingly stresses the importance of maintaining a neutral wrist position and avoiding hyperflexion to ensure consistent motion and avoid unnecessary strain. She demonstrates how to rock on the fulcrum rather than relying on finger motion, which is a more efficient way to initiate strokes. The summary includes a demonstration of controlled short strokes, the correct way to adapt the instrument to the tooth using a rolling thumb motion, and the technique for working on the interproximal and lingual aspects of the teeth. The emphasis is on using short, controlled strokes and maintaining the instrument handles parallel to the tooth to create an effective cutting edge.
