| Sumario: | While the presentation of Short Root Anomaly (SRA) in Hispanic patients has been described previously, it is not known if this population is predisposed to increased orthodontic root resorption. This study evaluates the response of pre-existing short roots in Hispanic SRA patients to orthodontic treatment. Selected maxillary and mandibular teeth of 40 Hispanic SRA patients (19 male, 21 female) and 40 age and gender matched Caucasian patients (19 male, 21 female) with normal root length were evaluated for root resorption following comprehensive orthodontic treatment. The age range of the subjects was between 10 and 19 years. Relative root length was calculated before and after orthodontic treatment from digital panoramic radiographs. Overall, statistically significant root resorption occurred in the control group, but orthodontic root resorption was not significant in the Hispanic group (p > 0.05). When genders were separated, Hispanic females did experience a mild degree of root resorption in the upper incisors while resorption in Hispanic males was not significant. Caucasian females experienced greater root resorption than Caucasian males. Hispanic SRA patients may be safely treated with comprehensive orthodontics and could be at no more risk of root resorption than Caucasian patients with normal initial root length. |
