Description
Summary:•First ever dental reference datasets based on two staging systems were developed for age estimation in Hispanic children and adolescents in Texas, United States.•Amongst the different dental age estimation methods, the unweighted method showed minimum difference in females and males in both the 8-stage and 14-stage systems.•The 8-stage system provided more accurate estimates of age and it is recommended for dental age estimation in Hispanic children and adolescents in Texas. Dental tissues follow a systematic pattern of development and several radiological methods have been developed and validated. This study aims to develop and validate a reference data set (RDS) for dental development of Hispanic children and to compare the mean age using the Demirjian and Moorrees tooth developmental stage (TDS) systems. A total of 600 Dental Panoramic Tomographs (DPTs) of Hispanic children aged 6 to 17 years were obtained and reference datasets (RDS) were developed by scoring all the maxillary and mandibular teeth in the left side of the arch according to the Demirjian (8 stage) and Moorrees (14 stage) scoring systems. To validate the RDS, 120 (DPTs) separate from the RDS were randomly selected, and dental ages were calculated from the RDS using unweighted and five weighted mean average methods. Statistical significance was set at p  0.05). For the 14-stage system, CA-DA for the unweighted method was 0.17 (0.33, 0.042) years for males, and 0.13 (0.41, 0.053) years for females. The difference was statistically significant for most of the Moorrees methods (p
