Although it has been known since 1917 that mottled dental enamel (later recognized as dental fluorosis—DF) is identical with that observed in thyroid dysfunction, disturbances of thyroid hormone metabolism during crucial periods of tooth development as the primary cause of DF have received very little consideration by dental researchers. New findings indicate that thyroid hormone metabolism is ...

Submit Manuscript | http://medcraveonline.com the posterior part of the jaws and consist of a disorganized mass with no morphologic resemblance to a tooth [1]. The lesions are invariably asymptomatic and are discovered on routine radiographic examinations; however, they may be associated with pathologic changes in adjacent teeth and structures such as-malformation, impaction, delayed eruption, ...

BP: bullous pemphigoid DP: dyshidrosiform pemphigoid INTRODUCTION Dyshidrosiform bullous pemphigoid (DP) is an unusual localized variant of bullous pemphigoid (BP), first described by Levine et al in 1979. It presents with a persistent and recurrent vesicobullous eruption, sometimes hemorrhagic, localized to the soles and/or palms. Since the clinical manifestations of DP are similar to those of...

Incontinentia pigmenti is a rare genodermatosis in which the skin involvement occurs in all patients. Additionally, other ectodermal tissues may be affected such as the central nervous system, eyes, hair, nails and teeth. The disease has an X-linked dominant inheritance pattern. But in our case, there was a mutation in the body cells due to incontinentia pigmenti. The dermatological findings oc...

AIDS was believed to be associated with a certain group of people, later the belief changed when the disease start encroaching other set of people. As science evolved, the knowledge about transmission of the virus grew and the evidences for the maternal transmission of the virus were found. Among children, most cases of infection by HIV are transmitted vertically, i.e., from mother to child. As...

Using a Potential Field Source Surface model (PFSS), we study magnetic field overlying erupted filaments in solar active regions. The filaments studied here were reported to experience a kink instability or a torus instability. The torus instability leads to a full eruption, while the kink instability leads to a full eruption or a failed eruption. It is found that for full eruption the field de...

Cleidocranial dysplasia (CD) is an autosomal dominant skeletal disorder with characteristic dental findings of numerous supernumerary teeth and noneruption of permanent teeth. This investigation compared the dental development and root lengths of the mandibular first permanent molar in 11 CD patients with those of 22 healthy, normal children matched for race, age and sex. The results showed tha...

Much interest has been expressed in recent years regarding various features common to dentitions with palatally displaced canines (PDC), particularly in relation to delayed dental development and reduced tooth size. The aims of the present study were to determine whether dentitions with buccally displaced canines (BDC) have features in common, which may be specific for the condition, when compa...

PURPOSE The purpose of this project was to establish median eruption ages of primary teeth and evaluate eruption differences between contralateral teeth by gender, ethnicity, and household income. Data was derived from a caries study of preschool children. METHODS A total of 4,277 white (non-Hispanic) and Hispanic preschool children from Arizona were visually examined for caries and tooth eru...
