Common Sampling Errors in Research Studies.

Proper sample selection is based on the study purpose, research question(s), and study design. Investigators must use care to select a sample population that is representative of the source and target populations. Well-defined inclusion and exclusion criteria serve as guidance when screening potential candidates for eligibility for participation in a study.

Training Dental Hygiene Students to Care for Patients with Disabilities.

The purpose of this study was to evaluate the impact of a novel training program on dental hygiene students' knowledge, attitudes and beliefs about caring for individuals with disabilities. A mixed methods approach was used. Students from five dental hygiene programs based at community colleges completed a two-hour didactic training session to supplement their existing special care dentistry coursework.

100 Years of Dental Hygiene Research: Progress and possibilities.

During the last century, the role of dental hygienists as leaders in the recognition, prevention, and treatment of oral diseases has grown, reflecting the ever-evolving knowledge base of the profession. The American Dental Hygienists' Association (ADHA) has contributed to and supported research that has formulated the scientific basis for the profession to inform education and practice. Progress has been made across multiple priority areas identified on the National Dental Hygiene Research Agenda, including educational research examining the impact of curriculum models on teaching and learning; health services research projects documenting workforce issues and cost-effectiveness of practice models; and public health initiatives expanding access to care to provide oral health care services for diverse patient populations.
