DMFTS+Index

dmfts Index

First thing… Dental Index is a standard quantitative method for measuring, scoring, and analyzing oral conditions in individuals and groups. Procedure: Examine each tooth in a systematic sequence making sure you have adequate light observing… Criteria for recording: Scoring Total each component separately: Total each D+M+F=DMF Question: An individual presents with dental caries on the mesial and occlusal surfaces of a posterior tooth, caries on the mesial surface of the anterior tooth, a molar tooth and anterior tooth are missing because of dental caries, and there is an amalgam restoration on the mesial distal occlusal surfaces of a posterior tooth. DMFT= DMFTS= (DMFTS can not be done off of records, need to talk to the person directly...this idex is more specific)
 * DMFTS Index- ** Decayed, Missing, or Filled Permanent Teeth or Surfaces
 * Category- ** Dental Caries
 * When is it used- ** To determine the status of dental caries activity/ experiences past or present, of decayed, missing, or filled teeth surfaces of permanent dentition by recording either the number of affected teeth or tooth surfaces.
 * Irreversible **
 * How is it used- DMFT ** is based on 28 teeth ( do not include the 3rd molars); **DMFS** is based on surfaces of 28 teeth;128 surfaces.
 * 1) 16 posterior teeth x 5 surfaces (facial, lingual,mesial, distal& occlusal) = 80 surfaces ( 16x5=80)
 * 2) 12 anterior teeth x 4 surfaces (facial, lingual,mesial, distal) = 48 (12x4=48)
 * 3) Teeth that are missing due to dental carries are recorded using 5 surfaces for posterior and 4 surfaces for anterior teeth.
 * **// Teeth not counted: //**
 * 3rd molars
 * Unerupted teeth
 * Congenitally missing & supernumerary teeth
 * Teeth restored for reasons other than carries
 * Primary tooth retained with the permanent successor erupted
 * 1) Each tooth is recorded once using the DMFT index
 * 2) 5 surfaces for posterior teeth and 4 surfaces for anterior teeth are recorded when using DMFTS index.
 * 3) DMF indices use a dichotomous scale (present or absent) to record decay
 * Decayed (D) - visible dental caries is present or both dental caries and restorations are present.
 * Missing (M)- A tooth has been extracted due to dental carries, or when it is carious, non-restorable, and indicated for extraction
 * Filled (F)- Ant permanent or temporary restoration is present or defective restoration without evidence of dental caries is present
