Fluorosis presents as irregular, diffuse enamel opacities which affect more than one tooth, in contrast to the well-demarcated borders of hypomineralised enamel seen in MIH. Amelogenesis imperfecta, a genetic condition; thus, there may be a history of similar defects in other family members. This condition affects both the primary and permanent ...
Turner's hypoplasia or Turner's tooth is a presentation of enamel hypoplasia that normally affects only a single tooth. Its causes can be the same as other forms of enamel hypoplasia, but it is most commonly associated with trauma to a primary maxillary central incisor and the subsequent developmental disturbance of the underlying permanent ...
Expansion of the cyst causes erosion of the floor of the maxillary sinus. As soon as it enters the maxillary antrum, the expansion rate increases due to available space for expansion. Performing a percussion test by tapping the affected teeth will cause shooting pain. This is often clinically diagnostic of pulpal infection. [citation needed]
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.
Fluorosis does not cause discolouration to the enamel directly, as upon eruption into the mouth, affected permanent teeth are not discoloured yet. In dental enamel, fluorosis causes subsurface porosity or hypomineralizations , which extend toward the dentinal-enamel junction as the condition progresses and the affected teeth become more ...
This diminishes the strength of the tooth which is called demineralization. For the outer layer of the tooth to reach cavitation, there is a breakdown of the enamel structure that allows the influx of the cariogenic bacteria. As cavitation progresses into dentine, the dental caries lesion becomes more severe, and this may cause tooth pain.
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]
