Background

The prevalence of gingival recession increases with age but is not a consequence of aging necessarily. The etiology is both complex and multifactorial, including anatomic, iatrogenic, and pathologic influences. Improper toothbrushing has been implicated as a contributing factor for many years without clear evidence to support the assumption. Short-term, longitudinal studies of manual and powered toothbrush use show gingival abrasions can be produced, but the relationship to gingival recession

Methods

The Medline, Embase, Web of Knowledge/Science, and Cochrane Oral Health Group Trials Register databases were searched, along with a hand search of the Journals of Clinical Periodontology, Periodontology, Periodontal Research, and IADR Abstracts. Nineteen articles addressing gingival recession were included in the review. A meta-analysis involved 159 subjects. Thirteen articles focused on NCCLs.

Results

Subjects were randomly assigned to use either a manual (MTB) or a power toothbrush (PTB) in the five randomized controlled trials (RCTs) included in the review of gingival recession. One study identified no significant increase in gingival recession adjacent to either canine or non-canine teeth after 6 months of brushing, but another found that both toothbrushes increased pre-existing gingival recession significantly over the course of 6 months. Two RCTs conducted 12-month studies comparing

Discussion

Some evidence suggests that patients with non-inflammatory gingival recession may benefit from the correct use of a manual or powered tooth brush to prevent gingival recession from becoming worse. The toothbrushing factors associated with the development and progression of gingival recession are frequency and method of brushing. Secondary factors include frequency of changing the toothbrush and stiffness of the bristles. Factors associated with the development of NCCLs include frequency of
