A recent study published in the Australian Dental Journal has revealed a significantly higher prevalence of dental staining among competitive young swimmers compared to non-swimmers. The research, conducted in Western Australia, highlights the link between swimming routines and oral health-related quality of life (OHRQL) and urges dentists to consider swimming habits as a potential risk factor for pediatric dental staining.
Research Overview
The cross-sectional cohort study evaluated 400 children who swim competitively and 400 non-swimmers. Parents and children from swimming clubs completed surveys assessing their swimming schedules, potential risk factors for staining, and OHRQL. Intra-oral photographs of the maxillary anterior teeth were taken, and staining was measured using a modified Lobene Stain Index. Key findings include:- Prevalence of Staining: 83% of swimmers exhibited staining compared to 44% of non-swimmers.
- Correlation with Swimming Hours: Staining severity, measured by the Global Stain Score (GSS), increased with total lifetime swimming hours and weekly practice time.
- Impact on Quality of Life: Staining negatively influenced the children’s self-esteem and overall oral health satisfaction, as reflected in their OHRQL scores.
Chlorine: The Culprit Behind the Stains?
The study suggests that the high prevalence of staining among swimmers could be due to prolonged exposure to chlorinated pool water. Chlorine interacts with saliva and dental plaque, forming compounds that adhere to the tooth surface and cause extrinsic discoloration.Free for members
