Internal resorption, a rare phenomenon, has been a quandary from the standpoints of both its diagnosis and treatment. It is usually asymptomatic and discovered by chance on routine radiographic examinations or by a classic clinical sign, “pink spot” in the crown. This paper emphasizes the etiology and pathophysiologic mechanisms involved in internal root resorption. Prognosis is good for smaller lesions; however, for those with extensive resorption associated with perforation the tooth structure is greatly weakened and the prognosis remains poor.
Prion diseases are a group of neurodegenerative disorders characterized by accumulation of abnormal prion proteins in the central nervous system. The prions resist conventional sterilization procedures especially when infected tissue becomes dried onto metal or glass surfaces. This article, a review of literature collected using Pubmed as search engine, describes the oral manifestations of prion diseases in addition to studying the possibility of cross contamination in the dental office. The article emphasizes the importance for dentists to be aware of these diseases, to identify the high-risk patients by obtaining adequate medical history and to know the appropriate deactivation procedures to be followed.
THE accumulation of neutral fac in the blood to such an extent as to produce turbidity of the serum is termed hyperlipaemia. This may occur physiologically after a fatty meal, secondarily to diabetes mellitus, the nephrotic syndrome and glycogen storage disease, or idiopathically.
Christ–Siemens–Touraine syndrome/hypohidrotic ectodermal dysplasia (HED) is a heterogeneous group of inherited disorders with primary defects in tissues derived from embryonic ectoderm such as hair, tooth, nail, and sweat glands. To date, more than 192 distinct disorders have been described. Here we present a case of 19-year-old female patient that manifested with HED (Christ-Siemens-Touraine syndrome).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
