considerations when using indices or evaluating studies using indices
1- Studies using different indices should be compared only as to general findings rather than specifics.2- An index should be selected according to its ability to evaluate the variable.3- Index methodology should not be modified.4- Plaque indices measuring presence/absence of plaque are for motivation, while those measuring quantity are for clinical trials and epidemiological surveys.5- Full mouth scoring is for clinical use or a small population group, while simplified indices are more useful for epidemiological studies and large clinical studies.6- Examiner intra- and inter- reliability should be established prior to use.
