Abstract

Objectives: to test the London atlas for dental age estimation in Thai population.

Materials and methods: The London atlas for age estimation was tested in 111 digital panoramic radiographs from the General Police Hospital, Bangkok, Thailand. The sample was composed of children (57♂ and 54 ♀) aged between 4.00 and 15.99 years. The intra- and inter-examiner variations of tooth stage reliability were tested in 10% sample using an Intraclass Correlation (ICC). The difference between chronological age (CA) and atlas for dental age (ADA) were investigated using a paired subjects t-test. The significance of the difference between CA and ADA was tested using the F-tests of the one-way ANOVA (P < 0.05 considered statistically significant). The analysis of variance considered the effects of sex, age group and the interaction between sex and age group. Other analyses included the difference of ADA by age group and the comparison between CA and ADA by sex. SPSS Statistics 24 was used for all analyses.

Results: ADA correlated to CA with a discrepancy of 1.3 years maximum. There was no significant effect of sex (F (1, 87) = 0.278, p = .600), age group (F (11, 87) = 1.032, p = .426) and sex and age group (F (11, 87) = 1.238, p .275) between CA and ADA.

Conclusions: The estimates of dental ages correlate and reasonably reflect the chronological ages of Thai children and adolescents for both males and females from age 4.00 to age 15.99.
