Evolution of Indices in the Screening of Periodontal Diseases: A Narrative Review

Periodontal disease is the inflammation of the periodontal supporting structures of teeth. An index is an important tool of surveillance system based on the requirements of reliability, simplicity, and validity to screen oral health disease of the population. This paper aims to discuss on various indices formulated to measure periodontal disease from past to present. This paper reviews indices and different recording systems used to measure periodontal diseases at the population level by retrieving articles, selecting, writing, and summarizing the article. The advantages and disadvantages of various indices used for measuring periodontal disease are discussed in this article. Community Periodontal Index is the most widely accepted index used in larger research studies. However, presently, clinical attachment loss is a widely accepted tool for the diagnosis of periodontal disease. Future advances in new screening methods will be able to provide new opportunities in the diagnosis of active and progressive periodontal disease, which will further help in more precise screening of periodontal disease in larger research studies.
