Study Notes

Indices

  • Express clinical observations using numbers.
  • Numbers give standardized, less subjective information about health conditions than word descriptions.
  • They measure oral hygiene status in clinical settings to educate and motivate patients
  • Findings determine daily oral care quality and monitor oral hygiene education program results in community settings.

Types of Scoring Methods

  • Individual Assessment Score: An index, biofilm record, or scoring system for patient education, motivation, and evaluation.
  • Clinical Trial: Determines the effect of an agent or procedure on disease prevention, progression, or control.
  • Epidemiologic Survey: Studies disease characteristics in populations (e.g., DMFT index) to determine a condition's prevalence and incidence in a given population.

Biofilm Index

  • Historically known as plaque index (PI Score).
  • Assesses biofilm thickness in the gingival area.
  • Requires use of a disclosing agent.
  • Can evaluate the entire dentition or selected teeth.
  • 0 = No biofilm
  • 1 = A film of biofilm adheres to the free gingival margin and adjacent tooth area.
  • 2 = Moderate soft deposits accumulate within the gingival pocket, visible with the naked eye on the tooth and gingival margin.
  • 3 = Abundance of soft matter is within the gingival pocket and/or on the tooth and gingival margin.

Biofilm Control Record Index

  • Previously known as the plaque control record
  • It records the presence of dental biofilm on individual tooth surfaces.
  • It permits the patient to visualize progress while learning biofilm control.
  • All teeth are included when using this index.
  • A disclosing agent is used as part of the process.

Biofilm-Free Score

  • Determines the location, number, and percentage of biofilm-free surfaces.
  • All erupted teeth are included in the assessment.
  • A disclosing agent is required.

Patient Hygiene Performance (PHP) Plaque Index

  • Purpose: Assess the extent of biofilm and debris over a tooth surface.
  • Selection of Teeth and Surfaces: Facial surfaces of incisors and maxillary molars
  • Lingual surfaces of mandibular molars (3,8,14,19,24,30) are also assessed.
  • Procedure: Requires a disclosing agent.

Simplified Oral Hygiene Index (OHI-S)

  • Assesses oral cleanliness by estimating debris and calculus coverage on tooth surfaces.
  • Six tooth surfaces are scored (3,8,14,19,24,30).
  • 0 = No calculus present
  • 1 = Soft deposit covers not more than 1/3 of the tooth surface
  • 2 = Soft deposit covers more than 1/3 of the tooth surface
  • 3 = Soft debris covers more than 2/3 of the tooth surface.

Sulcus Bleeding Index (SBI)

  • Purpose: Locate areas of gingival sulcus bleeding and color changes to recognize and record early inflammatory gingival disease.
  • Areas Examined: Four gingival units are systematically scored for each tooth.
  • Procedure: Walk the probe to the base of the sulcus, waiting 30 seconds before scoring apparently healthy gingival units.

Dental Caries Experience

  • Useful for measuring prevalence in groups.
  • Population scores document the number of persons in any age group affected by dental caries and the number of teeth needing treatment.

Dean's Fluorosis Index

  • Measures the prevalence and severity of dental fluorosis.
  • Developed in the 1930s and refined in 1942.
  • It relates the severity of hypomineralization of dental enamel to the concentration of fluoride in the water supply.

Permanent Dentition: Decayed, Missing, and Filled Teeth or Surfaces (DMFT)

  • Purpose: Determine total dental caries experience (past and present).
  • It is done by recording the number of affected teeth or tooth surfaces.
  • Selection of Teeth and Surfaces: Based on 28 teeth.
  • Decayed (D): Visible dental caries is present.
  • Both dental caries and a restoration may be present.
  • Missing (M): A tooth extracted due to dental caries, nonrestorable and indicated for extraction.
  • Filled (F): Any permanent or temporary restoration is present.
  • Defective restoration without evidence of dental caries.

Primary Dentition: Decayed, Indicated for Extraction, and Filled (df and def)

  • Purpose: Determine the dental caries experience for primary teeth in the oral cavity via teeth or surfaces.
  • Selection of Teeth or Surfaces: 20 teeth are evaluated.

Community-Based Oral Health Surveillance

  • WHO Basic Screening Survey: Collects comprehensive data on oral health status and dental treatment needs of a population.
  • Epidemiology: The study of health and disease in a population.
  • Incidence: The occurrence, rate, or frequency of a disease in a population.

  • Name of the index or indices used
  • Score calculated
