Abstract
AIM: The purpose of this study was to determine the prevalence of HSPM, its clinical presentation and any association to MIH in Jordanian children.
MATERIALS: A cross-sectional study involving six- to-eight-year-old schoolchildren was carried out by two calibrated examiners. The MIH/HSPM index was used for scoring defects. A self-administered questionnaires exploring pre-, peri-, and post-natal relevant histories were also completed by parents. Descriptive statistics and chi-square test were used for data analysis with a p set at 0.05.
CONCLUSION: MIH and HSPM were quite prevalent in Jordanian schoolchildren. The two conditions were significantly associated with each other, but HSPM was not predictive of MIH.
