The efficacy in plaque removal following a brushing exercise is a reduction from baseline plaque scores of 42% on average, with a variation of 30-53% dependent on the plaque index used. The available evidence indicates that bristle tuft arrangement (flat trim, multilevel, angled) and brushing duration are factors that contribute to the variation in observed efficacy.

: Aim: The aim of the study was to asses the effect of the use of interdental brushes (IDB) in patients as an adjunct to toothbrushing compared with toothbrushing alone or other interdental oral hygiene devices on plaque and the clinical parameters of periodontal inflammation.
Material and methods: MEDLINE–PubMed and the Cochrane Central register of controlled trials (CENTRAL) were searched through November 2007 to identify appropriate studies. Clinical parameters of periodontal inflammation such as plaque, gingivitis, bleeding and pockets were selected as outcome variables.
Results: Independent screening of the titles and abstracts of 218 MEDLINE–PubMed and 116 Cochrane papers resulted in nine publications that met the eligibility criteria. Mean values and standard deviations were collected by data extraction. Descriptive comparisons are presented for brushing alone or brushing and woodsticks; meta‐analyses were also performed for the floss comparison.
Conclusion: As an adjunct to brushing, the IDB removes more dental plaque than brushing alone. Studies showed a positive significant difference using IDB with respect to the plaque scores, bleeding scores and probing pocket depth. The majority of the studies presented a positive significant difference in the plaque index when using the IDB compared with floss.
The dental professional should determine, on an individual patient basis, whether high-quality flossing is an achievable goal. In light of the results of this comprehensive literature search and critical analysis, it is concluded that a routine instruction to use floss is not supported by scientific evidence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
