Should these supplemental assays be used routinely on every periodontal patient?

What will be an ideal response?

Assessment of subgingival flora can be done in the office by ordering tests that will determine what types of bacteria are on each tooth surface and in the periodontal pockets. Individual teeth are selected to determine elevated levels of disease-causing organisms. These tests are not routinely used on every periodontal patient but should be reserved for difficult refractory patients and to monitor post-treatment.
