Establishing dental recall interval for Pakistani children: a longitudinal study..
J Pak Med Assoc Jan ;71(7):1799-803.

To determine the caries increment rate in children to establish appropriate dental recall interval. The prospective longitudinal study was conducted from May 2016 to October 2017 in Bhakkar city of Punjab, Pakistan, and comprised schoolchildren aged 12 years. The caries progression rate was measured using the Modified Beck's method or adjusted caries increment. The response rate at baseline and at each follow-up was compared. Bonferroni correction was used to compare baseline mean caries increment with caries increment at 6, 12 and 18 months. Data was analysed using SPSS 17 and Stata 14. Of the 226 subjects enrolled, 183(81%) were present at the last follow-up. However, only 147(65%) subjects were available for all the four measurements. Significantly high caries increment among cavitated lesions was observed at all the three follow-ups compared to the baseline (p=0.0001). The caries increment rate was low in cavitated lesions, but when non-cavitated and cavitated lesions were merged, they showed high caries increment.
