| periodical index | Useful as a subject approach to the contents of a periodical issuing an annual, biennial, quinquennial, decennial, etc., index. The heading is used for the overall body of articles published by a periodical in the same sense that bibliography is useful when published as a single article. (12 Dec 1998) |

| Periodontal Disease Index | An index used for estimating the degree of periodontal disease based on the measurement of six representative teeth for gingival inflammation, pocket depth, calculus and plaque, attrition, mobility, and lack of contact. (05 Mar 2000) |
| periodontal index | A numerical rating scale for classifying the periodontal status of a person or population with a single figure which takes into consideration prevalence as well as severity of the condition. It is based upon probe measurement of periodontal pockets and on gingival tissue status. (12 Dec 1998) |
| metacarpal index | The average ratio of length to breadth of metacarpals II to V; this ratio is increased in the Marfan syndrome. (05 Mar 2000) |
| Robinson index | An index used to calculate heart work load. See: double product. (05 Mar 2000) |
| phagocytic index | The average number of bacteria observed in the cytoplasm of polymorphonuclear leukocytes after mixing and incubating, at 37캜, 1) a suspension of washed, presumably normal leukocytes, 2) the serum to be tested for opsonin, and 3) a young culture of microorganisms that are causing disease in the patient. Origin: L. Phagedaena, Gr Phago, To eat. (05 Mar 2000) |
| Rohrer's index | Body weight in grams times 100 divided by the cube of height in centimeters. (05 Mar 2000) |
| root caries index | The ratio of the number of teeth with carious lesions of the root, and/or restorations of the root, to the number of teeth with exposed root surfaces. (05 Mar 2000) |
| Russell's Periodontal Index | An index that estimates the degree of periodontal disease present in the mouth by measuring both bone loss around the teeth and gingival inflammation; used frequently in the epidemiological investigation of periodontal disease. (05 Mar 2000) |
| mitotic index | <cell biology, molecular biology> The fraction of cells in a sample that are in mitosis. It is a measure of the relative length of the mitotic phase of the cell cycle. (18 Nov 1997) |
| molar absorbancy index | Absorbance (of light) per unit path length (usually the centimeter) and per unit of concentration (moles per liter); a fundamental unit in spectrophotometry. Synonym: absorbancy index, absorptivity, molar absorbancy index, molar absorptivity, molar extinction coefficient. (05 Mar 2000) |
| Pirquet's index | An obsolete method of establishing the presence of malnutrition by dividing the weight (grams/10) by the sitting height (in cm); the cube root of the quotient if < 0.945 was considered as indicating malnutrition. (05 Mar 2000) |
| Colour Index | A publication concerned with the chemistry of dyes, with each listed dye identified by a five-digit Colour Index number, e.g., methylene blue is Colour Index 52015. (05 Mar 2000) |
| Plaque Index | An index for estimating the status of oral hygiene by measuring dental plaque which occurs in the areas adjacent to the gingival margin. (05 Mar 2000) |
| PMA index | An index which measures the presence or absence of gingival inflammation as occurring on the papillae or the marginal or attached gingivae. (05 Mar 2000) |
