When the managers of a periodontal clinical trial experienced a large gap between the projected number and the actual number of enrolled subjects within a planned time period, successful completion of the research was threatened.[1][1] This gap occurred when inclusion and exclusion criteria were too

Subject recruitment, retention, and compliance in clinical trials in periodontics.
TLDR
The recruitment process can be complicated by legal requirements of proper representation of sex and race characteristics or by stringent entry criteria, and complex designs have not yet shown to be cost-effective and may endanger recruitment success.
The advantages and disadvantages of running a clinical trial in general practices
TLDR
The experiences encountered in running a clinical trial on the use of a metal reinforced glass-ionomer cement in general dental practices imply that there can be major problems in undertaking clinical trials of this nature in the general dental service.
The Prevalence and Economic Impact of Low-Enrolling Clinical Studies at an Academic Medical Center
TLDR
Although a certain percentage of low-enrolling studies can be expected in any research organization, the overall number of such studies must be managed to reduce the aggregate costs of conducting research and to maximize research opportunities.

TLDR
This paper comments, with varying degrees of emphasis, on several issues pertinent to the analysis of periodontal trials, including the ways in which measurement variability may distort analytic results.
Protecting Human Research Participants
Research with human subjects can occasionally result in a dilemma for investigators. When the goals of the research are designed to make major contributions to a field, such as improving the
