RCI+Index


 * RCI: Root Caries Index**
 * Category:** Dental Caries


 * Description:** According to Stedman's Medical Dictionary, the ratio of the number of teeth with carios lesions of the root and restorations of the root to the number of teeth with exposed root surfaces. RCI requires recession. It only takes into consideration areas of root exposure. Attempts to assess the extent of root caries experience within the context of individuals at risk for the disease.
 * Root Caries Index is irrerversible.**

1. The area on the root surface has to be well-defined, discolored, and soft. 2. As the clinician examines the surface area, there should be some resistance with the explorer. 3. The lesion in question is located either at the CEJ or below the CEJ on the root surface. 4. Restorations on root surface only if the lesion originated at the CEJ or confined to the root surface completely.
 * C**RITERIA FOR DIAGNOSING ROOT CARIES:

**EXAMPLES: **

**Teeth #20, #21, #28,#29 have buccal recession ** **Tooth #20: composite restoration ** **Tooth #21: lesion or decay on buccal surface **

**Total number of teeth with restorations on root surface only and/or total number of teeth with lesions/decay on root surface only divided by total # of teeth that has recession (either lingual or buccal) X 100% = RCI. **

**#20 + #21 / #20 + #21 + #28 + #29 = Total teeth with restoration/decay / Total teeth with recession = 2/4 = 0.5 X 100 = 50%. **
