Study Notes
Instrument Handling and Transfers
- Class IV motion includes operating an x-ray unit.
- Two-handed instrument exchange is the preferred method for transferring surgical instruments.
- Single-handed instrument transfers are performed with the left hand.
- Instruments with hinges should be transferred by directing the handles into the dentist's palm, while the assistant holds the working end.
Patient Positioning
- The most common patient position during dental treatment is the supine position.
- Patients are usually seated in the supine position for dental procedures.
- The sub-supine position is when the patient's head is lower than the chest.
- The dental chair's headrest supports the occipital and cervical regions of the skull and neck.
Assistant's Role and Team Dentistry
- A dentist who trusts an assistant with a specific procedure is delegating tasks.
- Team dentistry, also known as four-handed dentistry, aims to improve workflow and efficiency while avoiding back pain and muscle strain.
- Dental assistants should maintain a stool height of 4-6 inches for better visibility during procedures.
- The dental treatment area is referred to as the dental operatory.
Infection Control and Patient Comfort
- Infection control protocols require cleaning the dental chairs after every patient to ease the process.
- Comforting the patient involves initiating conversation and addressing any treatment questions they may have.
