Ten Year Dental Maturation Comparison in a Southern California Hispanic Pediatric Population
Objectives: The aim of this study was to evaluate differences in dental maturation over a ten year time span in inland Southern California adolescent Hispanic population.
Methods: The comparative test population samples were a cross-section of 100 Hispanic adolescents from age 10 – 13 years in year 2018. The comparative sample (n=100) was a similarly aged population with data from the year 2008. The Demirjian molar development staging was used to record the developmental stage of first permanent molars (M1) and second permanent molars (M2) in all four quadrants as seen on panoramic radiographs.
Results: Significant differences between individual tooth maturation in 2008 and 2018 were observed in the maxillary right second molar (P = 0.015), maxillary left second molar (P = 0.033) and maxillary left first molar (P = 0.048). No significant difference between individual tooth maturation in 2008 and 2018 was noted in the maxillary right first molar (P = 0.055) and in all mandibular first and second molars. (P >0.05)
Conclusions: Dental maturity is generally accelerated for maxillary first and second molars in 2018 compared to 2008. Dental maturity occurs at the same rate for mandibular first and second molars in the time span between 2008 to 2018.
