Study Notes
GI Numbers and PLI Numbers
- GI numbers should be placed on the patient's chart, and PLI numbers should be placed on the patient's chart and on the treatment plan.
- The purpose of GI numbers is to record the severity of gingivitis and monitor the effectiveness of treatment.
Criteria for Normal Gingiva
- Normal gingiva is characterized by a GI score of 0, which indicates a healthy, pink, and firm appearance.
Characteristics of Mild Inflammation
- Mild inflammation is characterized by a GI score of 1, which indicates a slight change in color, a slight loss of texture, and a slight bleeding tendency.
Characteristics of Severe Inflammation
- Severe inflammation is characterized by a GI score of 3, which indicates a marked change in color, a marked loss of texture, and a marked bleeding tendency.
Disclosing Agent
- A disclosing agent is a solution or tablet that temporarily stains biofilm and plaque, making it visible for removal.
- When applied to the teeth, a disclosing agent stains areas where plaque and biofilm have accumulated.
- Disclosing agents can be found in various forms, including tablets, solutions, and sprays.
Purpose of Biofilm in OHI
- One of the purposes of biofilm in OHI is to provide a habitat for bacterial growth, which is not a correct purpose of biofilm in OHI.
Individualized Instruction in OHI
- The main factor that determines individualized instruction in OHI is the patient's unique needs and circumstances.
Purpose of OHI
- OHI aims to achieve patient education and motivation by pointing out where plaque has accumulated.
Types of Stain
- Thin, relatively clear stains that cover the teeth are typical of newly formed plaque.
- Thicker, older, and more tenacious stains are typical of plaque that has accumulated over time.
Tooth Tilt
- The type of tooth that tilts inward in the mandibular arch is the lingual inclination.
- The type of tooth that tilts outward in the mandibular arch is the facial inclination.
Working-End and Tooth Surface Adaptation
- The part of the working-end that should always be in contact with the tooth surface for correct adaptation is the tip-third.
Instrumentation Strokes
- The direction of instrumentation strokes is away from the soft tissue base of the sulcus or pocket.
- The exploratory stroke is used to evaluate the tooth surface and detect any abnormalities.
- The assessment stroke is another name for the exploratory stroke.
- The calculus removal stroke is used to remove calculus deposits, and it typically requires a universal curet or a sickle scaler.
- The root debridement stroke is used to remove residual calculus deposits from root surfaces that are exposed or within deep periodontal pockets.
Instrumentation Angulation
- The correct angulation for the face-to-tooth surface is between 45 and 90 degrees.
- The ideal angulation range for calculus removal is between 70 and 80 degrees.
- Angulation less than 45 degrees can cause tissue injury.
- Angulation greater than 90 degrees can cause tissue injury.
Instrumentation Pressure
- The correct pressure to be applied against the tooth surface during the root debridement stroke is light to moderate pressure.
Instrumentation Strokes on Different Surfaces
- Vertical strokes are used on the mesial and distal surfaces of posterior teeth.
- Oblique strokes are used on the facial and lingual surfaces of posterior teeth.
- The purpose of the oblique stroke is to remove plaque and calculus from the facial and lingual surfaces of posterior teeth.
Sickle Scaler and Universal Curet
- The tip-third of the sickle scaler is triangular in cross section.
- The correct angulation for the face-to-tooth surface of a sickle scaler is between 45 and 90 degrees.
- A universal curet is used to remove light supra and subgingival calculus deposits.
- The purpose of the rounded back on a universal curet is to facilitate adaptation to curved root surfaces.
- A universal curet has two cutting edges per working-end, which are positioned at a 90-degree angle to each other.
- The relationship between the two cutting edges of a universal curet is that they are perpendicular to each other.
Curet A and Curet B
- The main difference between Curet A and Curet B is the size and shape of the working-end, which determines the type of pocket they can be used in.
Calculus Removal
- Calculus removal strokes on anterior teeth typically require a universal curet or a sickle scaler.
- The angulation range associated with tissue injury is less than 45 degrees or greater than 90 degrees.
- The oblique stroke is typically used on the facial and lingual surfaces of posterior teeth.
