The study of the relationship between a person's body and their work environment.
What is Ergonomics?
This is what we call the clinician's angle of approach to a patient because it is compared to the numbers on a clock.
What is clock position?
This structure can be divided into the following parts: Free - Interdental - Attached - Junctional Epithelium - Mucogingival Junction - Alveolar Mucosa - Sulcus
What is the gingiva?
This mature, highly mineralized deposit is found apical to the gingival margin.
What is subgingival calculus?
This inflammatory lesion is usually not accompanied by any clinically visible signs of inflammation.
What is the initial lesion?
This is the recommended duration for toothbrushing.
What is 2 minutes?
This instrument is used for indirect vision, retraction and illumination.
What is the mouth mirror?
This is also known as the "tooth chart"
What is the odontogram?
When these body parts are in neutral position, they are flat on the floor, shoulder width apart.
What are the feet?
This trait of a clinician will determine whether they approach the patient from the right or left side.
What is dominant hand? (also acceptable: Left-or Right- handed)
This structure is the fibrous connective tissue that surrounds and attaches the alveolar bone to the cementum.
What is the Periodontal Ligament (PDL)?
This mature, highly mineralized deposit is found coronal to the CEJ.
What is supragingival calculus?
This inflammatory condition is contained within the gingiva and does not extend into other components of the periodontia.
What is gingivitis?
This is how often the ADA recommends replacing your toothbrush.
What is every 2-3 months?
This is the ring finger of your dominant hand during instrumentation.
What is a fulcrum?
The "O" in SOAP note stands for this.
What is Objective?
When this body part is in neutral position, the wrist is aligned with the forearm, and the little finger is slightly lower than the thumb.
What is the hand?
This range of clock position is used by both the right-and left-handed clinician for treating a patient's anterior teeth.
What is 11 o'clock to 1 o'clock.
This tissue is a thin layer of calcified connective tissue that covers the tooth from the CEJ to the apical foramen.
What is cementum?
This non-mineralized mixture of colonized bacteria, organic and inorganic elements, and extracellular matrix is found on the crowns of teeth.
Supragingival biofilm
This stage is the most severe stage of advanced periodontitis.
What is Stage IV periodontitis?
This is the ideal timing for giving oral hygiene instructions to your patient.
What is BEFORE you begin scaling (OR After assessment & Before scaling)
These parts of an instrument are labeled #3: 
What are the cutting edges?
This is a patient's subjective concerns about their oral health which should be documented and addressed first.
What is a chief complaint?
When these body parts are in neutral position, they are relaxed, and in a straight line, and NOT hunched forward or lifted toward the ears.
What are the shoulders?
This position for the left-handed clinician is equivalent to the 8 o'clock position for the right-handed clinician.
What is 4 o'clock?
This structure attaches the gingiva to the tooth, forms the base of the sulcus, and migrates apically when periodontal tissues break down.
What is the junctional epithelium?
The source of elements which mineralize this deposit are sulcular fluid and exudate.
What is sub-gingival calculus?
This denotes the rate of progression of periodontitis.
What is grade?
This interdental aid is the most effective for most patients, if appropriate sizes are used.
What is a proxy brush/interdental brush?
The cutting edge of this type of curet adapts only to specific surfaces/teeth.
What is area-specific?
This dental restoration material appears similar to natural tooth structure, both clinically and radiographically.
What is composite (or composite resin)?
When this body part is in neutral working position, the head is tilted forward 0-20° and there is a vertical line of vision from eyes to treatment area.
What is the neck?
The range of clock positions used by right-handed clinicians.
8 to 1 o'clock (also acceptable: 8-12 o'clock)
This means that pus is being discharged from a probing site.
What is suppuration?
This soft deposit is made up of 4 layers which include predominantly gram-negative anaerobic bacteria and other motile organisms.
What is subgingival biofilm?
The stage/severity of periodontitis is determined by: clinical attachment loss, tooth loss due to periodontitis, and this.
What is radiographic bone loss (RBL)?
This ingredient in toothpaste is known to reduce hypersensitivity by preventing the nerve impulse.
What is potassium nitrate?
This part of an instrument is labeled #2:
What is the face?
This is the name of the computer-generated notations that appear below the tooth chart.
What is "ledger"?
