Abstract

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, and a paired t-test was conducted to compare the difference between Chronological Age (CA) and Dental Age (DA) for each weighting method. For the 8-stage system, the mean (sd, se) difference between CA and DA for the unweighted method was 0.04 (0.51, 0.065) years for males, and 0.07 (0.41, 0.053) years for females. The difference was not statistically significant for all five weighting methods (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 < 0.05). Dental age derived from the unweighted average method using the reference dataset derived from Demirjian's 8-stage system is recommended for dental age estimation in Hispanic children and adolescents.
