Oral mucosal peeling related to dentifrices and mouthwashes: A systematic review.

BACKGROUND

The aim of this systematic review was to summarise the clinical information available about oral mucosal peeling (OMP) and to explore its aetiopathogenic association with dentifrices and mouthwashes.

MATERIAL AND METHODS

PICOS outline. Population, subjects diagnosed clinically and/or pathologically. Intervention, exposition to oral hygiene products. Comparisons, patients using products at different concentrations. Outcomes, clinicopathological outcomes (primary) and oral epithelial desquamation (secondary) after use. Study design, any. Exclusion criteria, reports on secondary or unpublished data, in vitro studies. Data were independently extracted by two reviewers.

RESULTS

Fifteen reports were selected from 410 identified. Descriptive studies mainly showed low bias risk, experimental studies mostly an "unclear risk". Dentifrices or mouthwashes were linked to OMP, with an unknown origin in 5 subjects. Sodium lauryl-sulphate (SLS) was behind this disorder in 21 subjects, tartar-control dentifrices in 2, and flavouring agents in 1 case. Desquamation extension was linked to SLS concentration. Most cases were painless, leaving normal mucosa after desquamation. Tartar-control dentifrices caused ulcerations more frequently.

CONCLUSIONS

OMP management should consider differential diagnosis with oral desquamative lesions, particularly desquamative gingivitis, with a guided clinical interview together with pathological confirmation while discouraging the use of the product responsible for OMP.
