Achondroplasia: craniofacial manifestations and considerations in dental management

Achondroplasia is the most common form of skeletal dysplasia dwarfism that manifests with stunted stature and disproportionate limb shortening. Achondroplasia is of dental interest because of its characteristic craniofacial features which include relative macrocephaly, depressed nasal bridge and maxillary hypoplasia. Presence of large head, implanted shunt, airway obstruction and difficulty in head control require special precautions during dental management. Craniofacial manifestations and considerations in dental management are presented in 11-year-old female patient with achondroplasia

effect of repeated applications of enamel surface treatment on in-vitro bovine enamel hardness after multiple exposures to cola drink

The aim of this study was to test the impact of repeated applications of various enamel surface treatments on the remineralization process after multiple exposures to cola drink, and to compare their ability to resist demineralization. Enamel demineralization and remineralization were monitored using surface microhardness. Bovine incisor teeth were exposed to cola drink for 2 minutes, 3 times per day for 3 days in the presence of artificial saliva. Then, the following surface treatment materials were tested: 1] Tooth Mousse, 2] MI Paste PlusTM, 3] Fluoraphat, and 4] Control [no treatment]. The procedure was repeated every 3 days for 12 days. Results showed that cola soft drink significantly [p < 0.05] decreased enamel microhardness. All tested enamel surface materials significantly [p < 0.05] increased the hardness of eroded enamel when repeatedly applied. MI Paste PlusTM showed better remineralization and higher resistance to erosion when compared to other groups. It was concluded that repeated applications of enamel surface treatment were effective in increasing enamel microhardness after erosion process, caused by multiple exposure to soft drink in bovine incisor teeth
