Nutritional status and the timing of deciduous tooth eruption.

The number of deciduous teeth in a sample of rural Ladino Guatemalan children was counted every 3 months through 24 months of age, and at 6-month intervals from 24 to 36 months. Nutritional status at birth, whether expressed as full-term birth weight or as maternal caloric supplementation during pregnancy, influences the timing of deciduous tooth eruption. Furthermore, the timing of deciduous tooth eruption seems more closely associated with postnatal weight than with birth weight. Although indices of nutritional deficiencies are associated with retarded tooth eruption, the use of mean number of deciduous teeth erupted as an estimate of mean chronological age in populations living under conditions of mild-to-moderate malnutrition is relatively accurate because errors of age estimation based on mean values for the present sample only vary between 1 and 2 months.

Semiconductor probe measurements in beagle pups during deciduous tooth development.

Bone-seeking radiopharmaceuticals were used together with clinical and radiographic procedures to study tooth development in dogs. Similarities in the pattern and time course of radiopharmaceutical uptake in jaw areas studied suggest that changes in alveolar bone metabolism are not closely related to eruption times of individual teeth.

[Delayed eruption of the premolar after pathological deciduous tooth root resorption].

The behaviour of eruption of lower premolars after pathological resorption of deciduous molar roots was examined on models and X-rays. The molars of the first dentition were shed earlier after pathological resorption of deciduous molar roots. Data of absence are measured in years in the presence of occlusal bone bridges. The middle values are more than three years. Eruption of permanent teeth happens years later or they remain impacted. Eruption dates of premolars after pathological deciduous root resorption and interruption of the lamina dura, and after physiological resorption are significantly earlier than if there is an occlusal bony bridge (p less than 0.01). The therapeutic consequence is the surgical liberation of such premolars and their removal.

Characterization of stem cells from exfoliated deciduous teeth from a patient with Alagille syndrome carrying a JAG1 mutation.

PURPOSE: Alagille syndrome (ALGS) is an autosomal dominantly inherited disorder primarily caused by mutations in the Jagged Canonical Notch Ligand 1 (JAG1) gene. Although many pluripotent stem cells are well established, no patient-derived stem cells from exfoliated deciduous teeth (SHED) have been developed. In this study, we aimed to establish SHED from an ALGS patient carrying a heterozygous JAG1mut mutation. METHODS: We isolated SHED from a deciduous tooth of an ALGS patient with a heterozygous JAG1 mutation (ALGS-SHED) by the colony-forming unit-fibroblast (CFU-F) method. We then compared the characteristics of ALGS-SHED and healthy donor-derived control SHED (CONT-SHED). RESULTS: ALGS-SHED displayed mesenchymal stem cell features as indicated by CFU-F formation, immunophenotype, and mesenchymal multipotency into adipocytes, chondrocytes, and osteoblasts. ALGS-SHED showed reduced population doubling capacity and exhibited induced chondrogenic potency and diminished osteogenic potency, but similar hepatic potency. ALGS-SHED damaged in situ potency to form bile duct-like tubular structures in the livers of chronically CCl4-injured mice. CONCLUSIONS: We successfully established ALGS-SHED from an ALGS patient carrying a heterozygous JAG1 mutation. Our established ALGS-SHED may represent a potential model for studying ALGS involving a JAG1 mutation.

Fetal alcohol syndrome.

A case of fetal alcohol syndrome in an 8-month-old infant is presented. Several of the maxillofacial anomalies associated with this syndrome were present. In addition, a large dentigerous cyst was found, a rare lesion occurring with a deciduous tooth and never before reported in association with fetal alcohol syndrome.
