Molar incisor hypomineralisation (MIH) is a type of enamel defect affecting, as the name suggests, the first molars and incisors in the permanent dentition. [1] MIH is considered a worldwide problem with a global prevalence of 12.9% and is usually identified in children under 10 years old. [2]
The diagnosis is made by the clinical picture and the chest X-ray, which demonstrates decreased lung volumes (bell-shaped chest), absence of the thymus (after about six hours), a small (0.5–1 mm), discrete, uniform infiltrate (sometimes described as a "ground glass" appearance or "diffuse airspace and interstitial opacities") that involves ...
Budtz-Jorgensen & Bertram (1970) used different terminology for the same changes: (1) Simple localized inflammation, (2) Simple diffuse (generalized) inflammation, and (3) Granular inflammation. Bergendal (1982) included only diffuse and papillary varieties and referred to atrophic or hyperplastic denture stomatitis.
In aqueous oral care gels the peptide is present as matrix. It binds directly as matrix to the tooth mineral and forms a stable layer on the teeth. [38] This layer does protect the teeth from acid attacks. It also occludes open dentin tubule and thus reduces the dental sensitivity.
High-resolution CT image showing ground-glass opacities in the periphery of both lungs in a patient with COVID-19 (red arrows). The adjacent normal lung tissue with lower attenuation appears as darker areas. Ground-glass opacity (GGO) is a finding seen on chest x-ray (radiograph) or computed tomography (CT) imaging of the lungs.
Hutchinson's teeth resulting from congenital syphilis. Hutchinson triad is a triad of signs that may be seen in late congenital syphilis, including: interstitial keratitis, malformed teeth (Hutchinson incisors and mulberry molars), and eighth nerve deafness. [1] [2] Late congenital syphilis typically manifests after 2 years of age. [3]
Transient tachypnea of the newborn occurs in approximately 1 in 100 preterm infants and 3.6–5.7 per 1000 term infants. It is most common in infants born by caesarian section without a trial of labor after 35 weeks of gestation. Male infants and infants with an umbilical cord prolapse or perinatal asphyxia are at higher risk.
Teething is the process by which an infant's first teeth (the deciduous teeth, often called "baby teeth" or "milk teeth") appear by emerging through the gums, typically arriving in pairs. The mandibular central incisors are the first primary teeth to erupt, usually between 6 and 10 months of age and usually causes discomfort and pain to the infant.
