Case reports and clinical trials conducted in different countries (i.e., the United States, Canada, Brazil, Germany, Finland, Sweden, Japan, India, and Sri Lanka) tend to find a positive relationship between the presence of more retained teeth in older ages and the prevalence of root caries in older adults. As this tendency has been shown to prevail globally, it is estimated that the predicted demographic elderly expansion may cause, in near future, a significant increment in the number of older population requiring an effective means of preventing and treating root surface caries. Based on these concerns, the editors of the series Monographs in Oral Science by Karger Publishers, Dr. Adrian Lussi and Dr. Marilia Buzalaf, have invited me to organize a book, in which it was reunited a team of experts who could provide a critical and comprehensive understanding on the different aspects concurring for the caries phenomenon development on dental root surfaces. This team effort turned into a superb publication; the different parts of the book are indeed at the top level. Collectively, the chapters of this book brought a wide picture of the state-of-the-art in the addressed themes, which in turn will hopefully serve as a reference for readers and encourage new researches in the area.
