Molar incisor hypomineralization (MIH) is a developmental defect of dental enamel that shares features with hypomineralized second primary molars (HSPM). Prior to permanent tooth eruption, second primary molars could have predictive value for permanent molar and incisor hypomineralization. To assess this possible relationship, a cross-sectional study was conducted in a sample of 414 children aged 8 and 9 years from the INMA cohort in Valencia (Spain). A calibrated examiner (linear-weighted Kappa 0.83) performed the intraoral examinations at the University of Valencia between November 2013 and 2014, applying the diagnostic criteria for MIH and HSPM adopted by the European Academy of Paediatric Dentistry. 100 children (24.2%) presented MIH and 60 (14.5%) presented HSPM. Co-occurrence of the two defects was observed in 11.1% of the children examined. The positive predictive value was 76.7% (63.9–86.6) and the negative predictive value 84.7% (80.6–88.3). The positive likelihood ratio (S/1-E) was 10.3 (5.9–17.9) and the negative likelihood ratio (1-S/E) 0.57 (0.47–0.68). The odds ratio was 18.2 (9.39–35.48). It was concluded that while the presence of HSPM can be considered a predictor of MIH, indicating the need for monitoring and control, the absence of this defect in primary dentition does not rule out the appearance of MIH.

Developmental enamel defects (DDE) are often used as indicators of general health in past archaeological populations. DDE include three common types of lesions: hypoplasia, diffuse, and demarcated opacities. Molar incisor hypomineralisation (MIH) was defined in 2001 as a qualitative enamel defect affecting first permanent molars and often permanent incisors. The European Academy of Paediatric Dentistry established criteria to diagnose MIH in current populations as demarcated white or yellow‐brown opacities of enamel with or without posteruptive breakdown. MIH is prevalent in current populations (average 14.2%) and may cause important damage to first permanent molars. Aetiological factors are uncertain. The discovery of MIH in archaeological skeletal collections based on macroscopic examination has been reported previously, in particular by Ogden and colleagues (2008). If MIH exists in past populations, there are profound implications regarding current aetiological hypotheses. Aims of the present study were to (a) reassess the London postmedieval archaeological collection from which the first cases of MIH were reported and evaluate the reliability of MIH diagnosis criteria in past populations and (b) differentially diagnose developmental defects of enamel and post mortem discoloration in the teeth. Contrary to the reported prevalence in the original study (93.2%), among 47 subadult (>18 years) individuals, a low MIH prevalence was determined (27%). Reliability of MIH diagnosis was tested with three MIH experts who were also physical anthropologists. Our study highlighted that the reliability of a macroscopic diagnosis of MIH in past populations is fair (Cohen's kappa = 0.35 ± 0.11; Fleiss's kappa = 0.3). It could explain the large differential in prevalence values in studies performed in archaeological collections. Pathological and taphonomic agents can produce enamel modifications indistinguishable from one another, even to an “experienced eye.” Here, we examined the literature to highlight potential differential diagnoses of MIH (taphonomic discoloration, amelogenesis imperfecta, fluorosis, rachitic teeth, etc.). Employing nondestructive analyses to characterise and diagnose tooth discoloration in past populations is highly recommended.

Hypomineralised second primary molars: prevalence, defect characteristics and possible association with Molar Incisor Hypomineralisation in Indian children

Abstract: The prevalence of HSPM in 6-8-year-old Indian children was 5.6 %. The severity of hypomineralisation was milder in FPM compared to SPM. The presence of HSPM was reported to have significantly higher odds for development of MIH in future.
