This study was undertaken to examine the effects of intubation on the enamel development of primary teeth in children intubated during the first 3 months of life. The teeth of 35 children were examined clinically for signs of defects. Dental enamel defects were seen in 26 (74%) patients; enamel hypoplasia was seen in 15 and enamel hypomineralization in 19 cases. In eight patients both enamel hypoplasia and hypomineralization were found. There was a preponderance of enamel defects in the right maxilla, which supports the hypothesis that an early trauma to mineralizing primary teeth caused by laryngoscope may lead to dental enamel hypoplasia.

While most dentate non-mammalian vertebrates possess simple conical teeth, some demonstrate complex tooth shapes. Lake Malawi cichlid fishes are an extreme example of this, exhibiting a myriad of tooth shapes driven by an ecologically derived rapid evolution of closely related but distinct species. Tooth shape in mammals is generally considered to be established by signaling centers called primary and secondary enamel knots, which are not believed to be present in non-mammalian vertebrates.

Summary: Hypophosphatasia (HPP) is a genetic disorder due to pathological variants in ALPL, the gene encoding tissue-nonspecific alkaline phosphatase (ALP). HPP is typically associated with bone-related symptoms, such as bone deformity, fractures and bone pain in children, but can appear in adults with symptoms resembling arthritis. A 22-year-old male experienced repeated and severe sudden attacks of joint pain in the elbows and knees.

Aims: This study aimed to evaluate the enamel remineralization effect of fluoride-incorporated bioactive glass (F-BG) toothpaste on artificial subsurface caries in primary teeth.
Materials And Methods: Forty sound primary maxillary incisors were subjected to a demineralizing solution for four days to induce artificial enamel caries. The teeth were randomly divided into four experimental groups ( = 10 per group): Group I, F-BG toothpaste (530 ppm fluoride) (BiominF); Group II, 0.

Phosphaturic mesenchymal tumor (PMT) is a rare benign mesenchymal tumor characterized by excessive secretion of fibroblast growth factor 23 (FGF23), leading to phosphate loss and systemic osteomalacia. Despite recent progress in PMT research, no consensus on diagnosis and treatment guidelines has been established. This case series describes the clinical and pathological features of six pathologically confirmed PMT patients treated at the Third Affiliated Hospital of Sun Yat-sen University from 2010 to 2024, aiming to provide new insights for the management of this condition.

The periodontal ligament (PDL) is a connective tissue, and PDL cells have a potential to differentiate into cementoblasts, osteoblasts, and gingival fibroblasts. This study investigated whether transcription factor c-Myb could induce differentiation of PDL cells for periodontal regeneration. PDL cells were isolated from extracted teeth and cultured.
