Clinical Report: Toothpastes may transiently alter salivary calcium
Overview
This study evaluated the short-term effects of different fluoride toothpaste formulations on total salivary calcium levels. Results indicated that while significant differences were observed immediately after brushing, these effects diminished and were no longer statistically significant after 60 minutes.
Background
Understanding the impact of toothpaste formulations on salivary calcium is important for assessing their effects on oral health. Salivary calcium plays a role in enamel remineralization and overall dental health. This study contributes to the evidence regarding the biochemical effects of commonly used toothpaste products.
Data Highlights
| Toothpaste | Calcium Concentration (ppm) | Time Point |
|---|---|---|
| Parodontax | 18.81 | Immediately after brushing |
| Dentalux | 36.57 | Immediately after brushing |
| Sensodyne | 37.70 | Immediately after brushing |
| Parodontax | 35.82 | 30 minutes |
| Dentalux | 39.15 | 30 minutes |
| Sensodyne | 39.74 | 30 minutes |
Key Findings
- Different fluoride toothpaste formulations produced varying total salivary calcium concentrations immediately after brushing.
- Parodontax showed significantly lower calcium levels compared to Dentalux and Sensodyne immediately after brushing.
- By 60 minutes, no statistically significant differences in salivary calcium levels remained among the three toothpaste formulations.
- The study did not find any significant effect of treatment sequence on salivary calcium levels.
- Limitations included the measurement of total salivary calcium rather than ionized calcium and the focus on a single brushing episode.
Clinical Implications
The transient changes in salivary calcium levels following the use of different toothpaste formulations may not have sustained relevance.
Conclusion
The study highlights the short-lived nature of the effects of fluoride toothpaste on salivary calcium levels.
