Background summary
Gingival recession, exposure of the root surface due to apical migration of the
gingival margin, affects a significant amount of the population. Recession can
be generalized as the result of destruction of tissue due to inflammatory
disease but can also be localized and mulitfactorial of aetiology (Smith 1997
PMID: 9083906). Toothbrushing is considered to predispose localized recession
(Boyle 1950, Miller 1950, Gorman 1967 PMID: 5230025) (Rajapakse 2007 PMID:
17953693). It is also known that toothbrushing can cause gingival abrasion
(Breitenmoser 1979 PMID: 374707). However, to what extant gingival abrasion
caused by toothbrushing is associated with inducing gingival recession remains
to be unclear (Addy & Hunter 2003 PMID: 12875306)
Study objective
The aim of the study is to assess the relation of gingival abrasion to
recession in both manual and power brush users.
Study design
The study is a single- center, examiner- blind, cross- sectional study design,
comparing gingival abrasion, recession, pocketdepth and plaque removal in
manual and power brush users. Study will consist of one study visit. Subjects
are not allowed not to brush their teeth for 48 hrs prior the examination to
allow plaque to accumulate and to resolve any abrasional effects of previous
brushing exercises on the gingival tissues. First gingivitis will be assessed.
Subsequently plaque and gingival abrasion will be evaluated prior and after
brushing (subjects will brush their teeth with their own brush in their
habitual manner). Subsequently recession, probing pocket depth will be
evaluated.
