Oligodontia is the agenesis of numerous teeth, and is commonly associated with specific syndromes and/or severe systemic abnormalities. In this paper a patient with 14 missing permanent teeth is presented clinically with her conservative and prosthetic treatments.
A study was conducted to determine the mercury concentration in urine after placement of dental amalgam restorations. The 24-h urine mercury levels in 10 children with a mean age of 8 years were determined before the amalgam restorations had been placed, and after placement. The urinary mercury content was measured by the cold vapor atomic fluorescence method. Mercury levels in the urine samples before placement of the amalgam restorations were below the detection limit, and the values obtained after placement, although detectable, were far below the limits stipulated by the World Health Organization. Under the conditions of this study, it is considered that the mercury levels released from dental amalgams are not high enough to cause any systemic toxic effect.
Dentin Adhesit, Cavi-Line and Kavite Lak cavity varnishes were applied to the walls of prepared Class V cavities in fifty-two caries free extracted molar teeth before placing amalgam fillings. Tests with Methylene Blue dye after thermocycling showed that all cavity varnishes showed significantly lesser marginal leakage when compared with the control group without any cavity varnish.
Bizarre-appearing gingival recessions that do not correspond to any known gingival disease or oral manifestation of any known systemic disease are called factitial (self-induced) gingival disease. Psychological factors are very important in their etiology. Generally, the lesions occur during the time the child is experiencing stress associated with the frustration of his or her dependency needs. Four cases of self-induced gingival recessions involving children aged 4 to 6 years are presented and investigated from the pedodontic, periodontologic, and psychiatric viewpoints.
The EEC syndrome (ectrodactyly-ectodermal dysplasia -clefting) is defined as a multiple congenital anomaly syndrome characterized by ectodermal dysplasia, distal limb anomaly, cleft lip/palate, and lacrimal duct anomalies. This case report reviews and presents clinical symptoms and treatment of the EEC syndrome.
Mercury hypersensitivity is an allergic response mediated by the immune system. allergic reactions to mercury and other constituents of amalgam have been documented, but are very rare. The common symptoms are dermatitis, eczema, urticaria, erythema, edema and itching, occurring primarily on the face, neck, limbs and upper torso. In this paper an interesting case of mercury hypersensitivity is investigated and discussed.
