Background & objectives: Various indices are available to record different grade of severity of dental fluorosis. These indices have chances of inter- and intra- examiner variability. Therefore, study was conducted to compare three different indices for recording dental fluorosis to find out the best and most practical index of recording dental fluorosis for field studies in children living in a fluoride endemic area. Methods: The severity grades were recorded in 300 schoolchildren aged 12-15 yr having dental fluorosis of low, medium and high fluoride areas using three different indices, viz. Dean's fluorosis index (1942), tooth surface index for fluorosis (TSIF, 1984) and ICMR index (2013). Dean's index was used as gold standard. Results: The occurrence of moderate and severe cases was higher as per the Dean's index and of mild and severe cases was higher as per the TSIF and the ICMR index. The mean time required for recording dental fluorosis as per Dean's index and TSIF was similar and almost double (1.25±0.05 min) of that required for ICMR index (0.68±0.20 min). The intra-examiner variability was found to be least in the ICMR index compared to Dean's index and TSIF. Interpretation & conclusions: The ICMR index is a simple index with objective scores and takes less time in recording the dental fluorosis as compared to Dean's index and TSIF in field studies.
