    Objective. The objective of this study was to determine if the standards of dental maturation of Demirjian et al. (1973, 1976) are applicable to British children. Design. The design was cross-sectional, retrospective. Sample and method. The sample comprised 521 London children of Bangladeshi and white Caucasian (English, Welsh and Scottish) origin aged between 4 and 9 years. Dental age was assessed by crown and root stages of seven mandibular teeth from rotational pantomographs. Dental age was compared to chronological age using a t-test. Results. Differences in dental maturation between the two ethnic groups were not significant. British children as a group were dentally advanced compared to the Canadian standards. The mean (± standard deviation) advancement in girls was 0.51 ± 0.79 years and in boys was 0.73 + 0.73 years. Conclusions. The standards of dental maturation described by Demirjian et al. (1973, 1976) may not be suitable for British children.
