Study Notes
- An index expresses clinical observations using numbers
- Using numbers provides standardized information for consistent, less subjective health condition observations
Oral Hygiene Indices
- Oral hygiene status indices can educate and motivate patients in clinical settings
- Community data collection can determine daily oral care effectiveness and monitor oral hygiene education program results
Types of Scoring Methods
- Individual assessment scores, such as biofilm records or scoring systems, are used for patient education, motivation, and evaluation
- Clinical trials determine the effect of an agent or procedure on disease prevention, progression, or control
- Epidemiologic surveys study disease characteristics in populations, such as the DMFT index
- Epidemiologic surveys determine the prevalence and incidence of conditions within a population
Biofilm Index
- Assesses biofilm thickness at the gingival area
- Traditionally known as the Plaque Index (PI Score)
- Requires the use of a disclosing agent
- Can evaluate the entire dentition or selected teeth
Biofilm Index Scoring
- 0: No biofilm
- 1: Biofilm adhering to the free gingival margin and adjacent tooth area
- 2: Moderate soft deposit accumulation within the gingival pocket, visible to the naked eye or on the tooth and gingival margin
- 3: Abundant soft matter within the gingival pocket and/or on the tooth and gingival margin
Biofilm Control Record Index
- Previously known as the plaque control record
- Records the presence of dental biofilm on individual tooth surfaces
- Helps visualize patient progress while learning biofilm control
- All teeth are included, requires disclosing agent
Biofilm-Free Score
- Determines the location, number, and percentage of biofilm-free surfaces
- Evaluates all erupted teeth using a disclosing agent
Patient Hygiene Performance (PHP) Plaque Index
- Assesses the extent of biofilm and debris on a tooth surface
- Evaluates the facial surfaces of incisors and maxillary molars, and lingual surfaces of mandibular molars (teeth 3, 8, 14, 19, 24, 30)
- Requires disclosing agent
Simplified Oral Hygiene Index (OHI-S)
- Assesses oral cleanliness by estimating tooth surfaces covered with debris and/or calculus
- Scores six tooth surfaces (3, 8, 14, 19, 24, 30)
- 0: No calculus present
- 1: Soft deposit covering up to 1/3 of the tooth surface
- 2: Soft deposit covering more than 1/3 of the tooth surface
- 3: Soft debris covering more than 2/3 of the tooth surface
Sulcus Bleeding Index (SBI)
- Locates areas of gingival sulcus bleeding and color changes
- Recognizes and records early inflammatory gingival disease
- Four gingival units are scored systematically for each tooth
- The probe must be walked to the base of the sulcus
- It is important to wait 30 seconds after probing before scoring seemingly healthy gingival units
Dental Caries Experience
- Useful for measuring prevalence in groups
- Population scores can document the number of persons in any age group affected by dental caries
- Population scores can document the number of teeth needing treatment
Dean's Fluorosis Index
- Measures dental flurosis prevalence and severity
- Originally developed in the 1930s and refined in 1942
- Relates the severity of hypomineralization of dental enamel to fluoride concentration in the water supply
Permanent Dentition: Decayed, Missing and Filled Teeth or Surfaces (DMFT)
- Determines total dental caries experience by recording the number of affected teeth or tooth surfaces
- Based on 28 teeth
- Decayed (D): Visible dental caries is present or both dental caries and a restoration are present.
- Missing (M): A tooth extracted due to dental caries, nonrestorable, and indicated for extraction.
- Filled (F): Any permanent/temporary restoration is present or defective, without any evidence of dental caries.
Primary Dentition: Decayed, Indicated for Extraction, and Filled (df and def)
- Determines the dental caries experience for primary teeth by surface or tooth evaluation
- Evaluates 20 teeth
Community-Based Oral Health Surveillance
- WHO Basic Screening Survey: Collects comprehensive oral health status and dental treatment needs data for a population
- Epidemiology: Studies health and disease in a population
- Incidence: The rate, occurrence, or frequency of a disease in a population
Documentation
- Documentation should include the name of the used index/indices.
- Documentation should also include the calculated score.
- An objective statement providing an interpretation of the index score should be made
- The documentation must include follow-up instructions.
