Objectives
To assess whether salivary buffer capacity is associated with diet.
Search strategy
The trials were identified from a search of the PubMed database on: January 5, 2008 using the terms: "Diet"[Mesh] AND Salivary buffer activity and a search of the LILACS database on: April 7, 2008 using the terms: Diet$ and saliva$ and tamp$
Inclusion criteria
All in-vivo or in-situ randomized/quasi-randomized control trials; case control trials (CCT) and COHORT studies with relevance to review question; published in English or Portuguese.
Data collection and analysis
The systematic literature search identified 3 articles in compliance with the broad inclusion criteria. Of these, 1 article was rejected due to insufficient internal validity. Meta-analysis was not conducted.
Main results
In the 2 accepted trials a significantly lower buffer capacity was observed in association with high-energy intake in diet, low intake of fibers in diet and chronic protein-energy malnutrition. However, no causal relationship could be found.
Authors' conclusions
Only 2 trials have been found indicating that a high-energy intake in diet, low intake of fibers in diet and chronic protein-energy malnutrition are associated with low buffer capacity of stimulated saliva. These results are still insufficient in order to draw any reliable conclusions.
