Application of matched pair procedures to site-specific data in periodontal research.

Abstract:

:Application of standard statistical procedures to site-specific data in periodontal research is invalid unless site-to-site dependencies are accounted for. In this paper, we present the adjustments required for valid application of matched pair procedures, including the paired t-test and McNemar's chi 2 test for correlated proportions. Examples are given involving data arising from: (1) the comparison of pre- and post-treatment clinical measurements; (ii) split-mouth protocols.

  • Oral hygiene phase revisited: How different study designs have affected results in intervention studies.

    abstract::Every periodontal researcher have been taught, and every textbook in periodontics have advocated, that a phase in which the patient is meticulously motivated and instructed in proper oral hygiene-the oral hygiene phase-must be included in any periodontal intervention. However, how is this oral hygiene phase actually p...
