Study Notes
Dental Staining and Removal
- Images of stained teeth were shown to grab attention
- Learning Outcomes for GDC are listed
- 1.1, 1.1.1, 1.1.8, 1.2.1, 1.2.2, 1.2.4, 1.5.3, 1.5.5, 1.7.3, 1.7.7, 1.7.8, 1.9.1, 1.10.2, 1.10.3, 1.10.4, 1.10.5, 1.10.6, 5.2
- Formative assessment involves completing a workbook.
- Classification of stains:
- Intrinsic: Originates from within the tooth's structure.
- Extrinsic: Originates from outside the tooth.
- Types of dental stains are not all the same.
- Some are directly on the hard or soft deposits of the teeth
- Some are within the tooth’s structure
- Correctly identifying the type of stain will help with removal/prevention
- Examples of extrinsic stains include:
- Yellow
- Green
- Brown
- Orange
- Black
- Metallic
- Black lines
- Extrinsic stains are on the tooth’s outer surface, caused by topical or extrinsic agents and can be removed, examples include coffee, tea, wine, and tobacco.
- N1-type dental stains bind to the tooth surface via ion exchange.
- Examples include bacterial adhesion to pellicle, tea, coffee, metals, and wine.
- N2-type dental stains have a chromogen that changes color after binding, such as aged food.
- N3-type dental stains involve a colorless material that undergoes a chemical reaction to create a stain, such as browning foods high in carbohydrates or sugars, cooking oils, baked products, and fruit.
- Predisposing factors for staining include:
- Enamel defects
- Salivary dysfunction
- Poor oral hygiene
- Microscopic pits and fissures
- Bacteria
- Causative agents for extrinsic stains include foods like coffee, tea, and red wine. Smoking and other habits like chewing tobacco may also cause staining.
- Stains can become a nidus for plaque retention, so removal is important for aesthetic reasons.
- Stains may indicate poor oral hygiene in patients.
- Methods for removing extrinsic stains include:
- Good oral hygiene
- Polishing
- Debridement/PMPR
- Power-driven scaler/air polishing
- Bleaching/Whitening
- Methods for removing intrinsic stains include:
- Vital bleaching
- Cosmetic dentistry/veneers
- Micro abrasion
- Non vital bleaching
- Composite resin restorations
- Some techniques available for stain removal were shown in images
- Final thoughts on why stains need to be removed:
- Stain is unsightly
- Stain is rough and promotes plaque retention
- Could be covering calculus (tartar)
