Study Notes
Cavity Classification
- Class I involves pits and fissures on occlusal surfaces of molars and premolars, and buccal or lingual pits of molars as well as lingual pits of maxillary teeth.
- Class II affects the proximal (mesial or distal) surfaces of premolars and molars, indicating cavities in these areas.
- Class III targets the proximal surfaces of incisors and canines, focusing on decay in the tooth structure.
- Class IV addresses proximal surfaces of incisors or canines that involve the incisal edge or angle, indicating extensive decay.
- Class V pertains to decay in the gingival third of any tooth's facial or lingual surface, also known as smooth-surface decay.
- Class VI refers to the incisive edges of anterior teeth and cusp tips of posterior teeth, often caused by wear or defects.
Tooth Condition Indicators
- Impacted or unerupted teeth are not exposed in the mouth, marked with a red circle around the entire tooth including the root.
- Missing teeth are marked with a black/blue "X"; entire quadrants or arches can be represented by a single "X" if edentulous.
- A tooth to be extracted is indicated by a red diagonal line through the tooth, or alternatively, two red parallel lines.
Caries and Restorations
- Caries for Class I affects occlusal surfaces, outlined in red for composite and shaded for amalgam; previously restored areas are marked in black/blue.
- For Class II restorations, the caries impact occlusal and interproximal surfaces of posterior teeth with similar marking conventions for restorations.
- Class III caries indicate decay for anterior teeth, outlined and marked according to the same color scheme.
- Class IV caries affect incisors and require similar marking techniques.
- Class V caries occur in the gingival third with corresponding markings for restorations.
Additional Dental Conditions
- Recurrent decay is diagnosed via radiographs or existing restorations and indicated by outlining in red where decay is identified.
- Sealants are preventive measures applied in fissures marked with an "S" for identification.
- Periapical abscess refers to infection in the pulp, marked by a red circle at the root's apex.
- Root canals indicate pulp therapy needs, marked by lines through affected roots.
Restorative and Prosthetic Treatments
- Veneers are thin porcelain or composite covers for teeth, indicated by red outlines.
- Inlays and onlays are conservative restorations, outlined with specific color code indicators depending on the material used.
- Porcelain fused to metal (PFM) crowns combine esthetics with strength marked in specific ways.
- Gold crowns are indicated with diagonal lines, showing full coverage with a distinct marking system.
- Stainless steel crowns are primarily used for primary molars, marked with "SS" on the occlusal surface.
Dental Appliances and Conditions
- Post and Core procedures provide added strength post-root canal, marked with a triangular line.
- Fixed bridges restore missing teeth areas, indicated with "X" through missing tooth roots.
- Implants involve complete tooth and root replacement, marked by horizontal lines.
- Rotated teeth are denoted by a red arrow indicating the turn direction.
- Drifting teeth show positional shifts, marked with direction arrows.
- Diastema indicates spacing between teeth with vertical red lines.
- Fractured teeth or roots are marked with a red zigzag line.
- Dentures, both complete and partial, are indicated by a complete line below tooth roots, color-coded for fabrication status.
