Developments in dental plaque pH modelling

Objectives The objectives of this review were to give a comprehensive account of the methods used to determine dental plaque pH over the last 50 years, to review how these methods have been used in dental cariology research and to give an update as to how dental plaque pH studies might be developed in the future. Data Published, referred papers and abstracts of conference proceedings in the literature were reviewed. Sources A comprehensive search of the electronic databases PubMed® and Medline®, was undertaken. In addition, a hand search of the Index Denticus was done to identify relevant citations before 1966. Study selection Relevant published literature in peer-reviewed publications was reviewed. No additional inclusion criteria were applied. Conclusions This comprehensive review gives an account of the background to, history of, relative merits and demerits of, applications of and future of dental plaque pH technologies.
