简要总结
The second primary molar (SPM) development start at the same time as development of the first permanent molars (FPM) and permanent incisors so any systemic disturbance - causing stunted growth -occur , will result in hypo-mineralization of SPM as well as FPM and permanent incisors (Butler 1967, Weerheijm and Mejàre 2003).
The literature shows no previous studies that discuss the association between hypo- mineralized second primary molar (HSPM), MIH and the stunted growth in children.
aim: Estimate Prevalence of HSPM and MIH in stunted children.Evaluate the association between HSPM, MIH and the stunted growth in a group of Egyptian children.
• The diagnostic criteria for MIH established based on the European Academy of Pediatric Dentistry criteria (Weerheijm and Mejàre 2003) while diagnostic criteria for HSPM was established by (Elfrink et al. 2008).
