Study Notes
Caries Management Approaches
- Caries management includes extractive, operative, and preventative strategies.
- Preventative management prioritizes prevention over intervention, operating only when cavitation occurs and emphasizing minimally invasive techniques.
Simple Descriptions of Caries
- Simple descriptions provide an easily understandable framework for discussing caries but may oversimplify the disease.
Advantages of Simple Descriptions
- They are straightforward and easy to use.
- Widely adopted in educational and clinical settings.
Disadvantages of Simple Descriptions
- Limited to a one-dimensional view, representing only one aspect of caries.
- Lacks recognition of the complete disease process and offers no management advice.
- Subjective interpretation can lead to inconsistencies.
Epidemiological Caries Classification Systems
- Includes WHO-DMF, complications like pulp involvement, ulceration, fistula, and abscess.
- Caries Assessment Spectrum Treatment (CAST) provides a spectrum for assessing caries severity.
Clinical Caries Classification Systems
- GV Black's Classification includes six classes based on caries location.
- Mount-Hume, ADA Caries Classification System, Nyvad's criteria, and International Caries Detection and Assessment System also serve as classifications.
Purpose of Multiple Classification Systems
- Different systems cater to varying needs in epidemiology, education, and clinical practice.
- Caries detection has multiple levels, ranging from absence of obvious caries to comprehensive staging of severity.
Key Epidemiological Measure
- WHO-DMFT is the primary measure for assessing caries prevalence in populations.
WHO-DMFT Level 1 System
- DMFT counts decayed, missing, and filled teeth; uppercase for secondary dentition, lowercase for primary.
- Scores range up to 32 for DMFT (tooth unit) and 0-148 for DMFS (tooth surface unit).
Limitations of WHO-DMFT
- Cannot be used clinically due to discrete data nature (individual patient assessment).
Issues with WHO-DMFT
- Focuses on cavitated lesions, ignores initial caries; relies on clinical rather than radiographic evaluation; assumes caries as the cause for difficulties in teeth.
PUFA Level 1 System
- Records presence of severely decayed teeth (P), ulceration (U), fistula (F), and abscess (A).
Limitations of PUFA
- Exclusively epidemiological, only addressing advanced lesions without initial caries information.
Caries Assessment Spectrum and Treatment (CAST)
- Facilitates an understanding of caries severity through a structured index.
Issues with CAST
- More time-consuming than simpler classification methods.
GV Black's Classification Details
- Class 1: Pits and fissures (molars, premolars, maxillary incisors).
- Class 2: Proximal surfaces of molars and premolars.
- Class 3: Proximal surfaces of incisors and canines (non-incisal angle).
- Class 4: Proximal surfaces of incisors or canines (incisal edge involved).
- Class 5: Cervical third of facial/lingual surfaces.
- Class 6: Cavity on incisal edges of anterior teeth and cusp tips of posterior teeth.
Advantages of GV Black's Classification
- Globally recognized, practical, and historically established in general dental practice.
Disadvantages of GV Black's Classification
- Not suitable for preventative dentistry; focuses exclusively on cavitated lesions.
- Lacks information on non-cavitated lesions and activity of lesions, leading to potential underestimation of caries severity.
Mount-Hume Classification System
- Measures caries site and size, with site categories including pit and fissure, approximal, and cervical/root.
- Size categories range from minimal involvement to extensive bulk loss of tooth tissue.
Advantages of Mount-Hume Classification
- Emphasizes the natural disease process and provides a detailed description of severity.
Disadvantages of Mount-Hume Classification
- Specific limitations in clinical size estimations and operational constraints.
