“…EDS can analyse components without damaging the sample and provides high sensitivity for major elements of dental hard tissue (Das et al., 2016 ). A previous study showed that enamel experiences a reduction in microhardness as the mineral content and Ca/C ratio decrease (Fagrell et al., 2010 ).…”

A 10‐year‐old neutered male Chihuahua presented with unilateral dental erosion that occurred after several months of oral medications mixed with honey. A pH test was performed on all oral medications administered to the dogs to determine the cause of enamel erosion. Among the medications, the only acidic medication was clopidogrel (pH 2.65). To evaluate the effect of clopidogrel on the tooth surface under the same conditions as in the present patient, an additional preliminary study was designed in which two extracted teeth of another dog were immersed in a clopidogrel–honey mixture or only in honey. After a 3‐week soaking of the extracted tooth in the clopidogrel–honey mixture, field‐emission scanning electron microscope analysis revealed a rougher surface, whereas energy‐dispersive X‐ray spectroscopy analysis showed a reduced Ca/C ratio compared to the control tooth. In this case, prolonged exposure of the tooth surface to clopidogrel may be a cause of dental erosion.

Molar-incisor malformation (MIM) is a new type of root anomaly reported recently. The characteristics of MIM are dysplastic root formations, constriction of pulp chambers and presence of calcified matrices at the level of cementoenamel junction in permanent first molars and primary second molars. In some cases, permanent maxillary incisors are also affected.The permanent first molars of the patient in this case report were affected with MIM. Generalized pulp stones were observed in overall primary dentition. Micro-computed tomography (micro-CT) imaging and scanning electron microscope-energy dispersive X-ray spectrometer analysis were performed on the extracted mandibular first molar and maxillary primary second molar of the patient. Micro-CT images revealed the discontinuity of enamel directly connected to an accessory canal of the root.

“…Кроме гистологического строения твердых тканей зуба следует отметить изменения в минеральном составе временных зубов. По многим исследованиям были получены такие результаты, что содержание кальция и фосфора было значительно снижено в каждом слое, что подтверждает плохую минерализацию дентина и эмали [20,22,46]. По данным некоторых исследований околопульпарный дентин во временных зуба был менее минерализован и содержание кальция и фосфора было резко снижено [15].…”

Aim. Features of microscopic structure of enamel and dentin of intact temporary teeth, which are the cause of their reduced caries resistance. Materials and methods. Current information in the electronic databases Google Scholar and PubMed was examined through a systematic literature review. Articles with content related to the prevalence of dental caries in temporary teeth and the relationship between caries and tooth hard tissue structure were selected and included. Results. A total of 327 publications were reviewed. After analyzing the literature according to the inclusion criteria, the final number was 52. Conclusions. Based on the analyzed data, the structure of the hard tissues of temporary teeth is a predisposing factor for the occurrence and development of dental caries. Decreased thickness of enamel and dentin, increased concentration of organic matrix in them due to incomplete mineralization, microporosity of enamel, abnormal development of dentin layers, increased number of hypomineralized and irregular areas, underdevelopment of pulp, impaired function of odontoblasts, increased adhesion of microorganisms to the enamel surface – all these features contribute to the rapid and progressive development of caries in temporary teeth.

Comparison of the chemical composition of normal enamel from exfoliated primary teeth and teeth affected with early childhood caries: an in vitro study

Abstract: This study showed significant differences in the P content and Ca/P ratio between the enamel from teeth with ECC and in that from healthy primary teeth. These findings indicate that differences in the composition of enamel could be a risk factor for ECC.
