It is not necessary to advise the patient about oral hygiene, as this is a habit acquired in childhood that is difficult to change. Psychometric testing of instruments is the application of specific research methods designed to evaluate the amount of error contained within an instrument (. Three types of evidence are commonly examined to support the validity of an assessment instrument: content, construct, and criterion. To complement toothbrushing, the use of dental floss or tape is extremely important in removing biofilm on the occlusal surfaces.E. Educational Research Association, American Psychological Association & National Council on Measurement in Education, 1999). The ideal toothbrush is one that has a small head, soft bristles and straight handle and is indicated for all patients, regardless of their physical characteristics.D. Toothbrushing cannot be considered the only measure to prevent caries and periodontal diseases, so that oral hygiene needs to be seen as an essential requirement of healthy habits of the individual.C. There is no association between the prevalence of dental caries and poor oral hygiene therefore, this method cannot be considered as a preventive measure for caries disease.B. With regard to oral hygiene, mark the CORRECT OPTION:A. Reliability is consistency across time (test-retest reliability), across items (internal consistency), and across researchers (interrater reliability). Toothbrushes are the most common tools used by individuals for oral hygiene. It is the most effective dental cleaning resource. Replicability means whether the research results can be used for. The mechanical control of dental biofilm is related to the removal of biofilm at acceptable levels, through mechanized methods, with emphasis on brush Reliability is the degree to which an assessment tool produces stable and consistent results. Reliability means whether the research method will produce similar results multiple times.
