Epidemiological studies in dental diseases rely heavily on dental indices to assess the incidence, prevalence, and severity of conditions, which inform preventive strategies. These indices translate clinical observations into numerical values, allowing for a more objective evaluation compared to verbal descriptions. Different indices have been created to measure aspects like dental caries and fluorosis, categorizing conditions based on severity. Additionally, factors related to gingivitis and periodontal diseases contribute to the development of these indices, enhancing their effectiveness in dental health assessments.

Carefully crafted for both undergraduate and postgraduate students, this textbook offers a thorough overview of the subject, integrating both established and contemporary concepts. Several chapters introduce innovative approaches, ensuring a comprehensive understanding without oversimplifying key ideas. The authors are open to feedback and committed to addressing any oversights in future editions, emphasizing their dedication to continual improvement and accuracy in the material presented.

The book delves into the nature of dental caries, defined as an infectious disease leading to the decay of tooth tissue. It highlights the alarming rise of this condition in developing countries and identifies four key factors for its development: susceptible host tissue, cariogenic microflora, a suitable substrate, and time. The text discusses the roles of specific bacteria, such as Streptococcus mutans in early enamel lesions and Lactobacilli in dentinal caries, while also touching on the epidemiology of the disease.
