The Prevalence of Orthodontic Treatment Needs in Indian Population: A Systematic Review

AIM: This systematic review assesses the literature regarding the need for orthodontic treatment in the Indian population between the age group of 7 to 25 years of age. BACKGROUND: Electronic databases, including PubMed, Google scholar, Cochrane, DOAJ, Lilac and Scopus, were searched from July 2018 to January 2019, with hand searching of selected orthodontic journals undertaken to identify any missed-out records. Selection criteria included Indian population in various states of India with permanent or mixed dentition of age group 7 to 25 years where the Orthodontic treatment need was measured using IOTN and/or DAI. The quality of included studies was assessed with the use of the modified STROBE (Strengthening the Reporting of Observational studies in Epidemiology) approach. Inter-rater agreement of the review authors was used for the inclusion of primary articles, risk of bias assessment, and evaluation of the quality of evidence (modified STORBE).
