1/6. Oral rehabilitation of a bulimic patient: a case report.bulimia nervosa is among the most common health problems in contemporary society. It is a self-induced weight loss syndrome associated with distinct dental manifestations involving physical and psychologic symptoms. It is characterized by recurrent binge-purge episodes that occur at least once a day. This article describes the complete-mouth rehabilitation of a bulimic patient with a generalized enamel erosion of her dentition and a poor esthetic appearance. Porcelain-fused-to-metal restorations were used as the definitive treatment. Good esthetics and high self-esteem were the final results. Comprehensive restorative therapy was applied in this clinical case report to achieve both function and esthetics in a demanding situation.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/6. Full-mouth rehabilitation of a patient with bulimia nervosa. A case report.anorexia and bulimia nervosa are eating disorders seen mainly in adolescents or young patients. The dentist should be in the position to recognize early signs of the disorder and alert the patient (and the patient's parents, if necessary) of the possible physical, psychologi cal, and dental consequences. Such dental treatment may help motivate the patient to confront the problem. In this paper the full-mouth rehabilitation, using a combination of galvano- and metal-ceramic restorations, of a young patient suffering from bulimia nervosa is described.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
3/6. silver-alloy powder and glass ionomer cement.This article examines some physical property improvements made when a spherical silver alloy powder is added to a hydrous, restorative (type II) glass ionomer cement. When this first metal-reinforced glass ionomer cement is handmixed thickly and quickly, physical properties and clinical handling are improved. These various improvements make this metal-reinforced cement similar in clinical applications to a biocompatible dental epoxy. Three clinical cases are illustrated to show how simply this metal-reinforced glass ionomer cement can be used in dental practices.- - - - - - - - - - ranking = 2keywords = physical (Clic here for more details about this article) |
4/6. Dental erosion in patients with chronic alcoholism.tooth wear attributed to the physical wear of teeth by clenching and grinding (attrition) has been described previously in alcoholic patients. However, the pattern of wear seen in the series of cases reported here is more consistent with chemical damage (erosion) than attrition. A possible mechanism for this process is suggested, and it is further suggested that erosion is likely to play a more important role in the wear of the teeth in chronic alcoholic patients than attrition.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
5/6. The use of adhesive metal-ceramic restorations as an alternative to conventional crown and bridge materials.A compromise is often necessary when choosing the most appropriate material in the construction of crowns and bridges. The most commonly used material is porcelain fused to metal since it is aesthetic and has acceptable physical characteristics to be used in the restoration of both anterior and posterior teeth. Unfortunately, to achieve a predictable and durable result extensive tooth preparation is invariably necessary. More conservative alternatives such as dentine-bonded crowns may have inferior physical characteristics and allow less predictable control over the occlusal contour. This paper describes the construction of fixed restorations which use both lost wax and refractory die techniques in their construction. This results in a restoration which has the combined advantages of both traditional porcelain fused to metal and dentine-bonded crowns and bridges.- - - - - - - - - - ranking = 2keywords = physical (Clic here for more details about this article) |
6/6. sports drinks hazard to teeth.OBJECTIVE: To determine the dental hazards associated with sports supplement drinks by investigating the chemicophysical properties of eight brands of sports drinks. methods: The pH and titratable acidity against 0.1 M NaOH was measured. calcium, phosphate, and fluoride concentrations and viscosities of Carbolode, Gatorade, High Five, Isostar, Lucozade Sport Lemon, Lucozade Sport Orange, Maxim, and PSP22 were determined. RESULTS: The pH values of the drinks ranged from 4.46 (Maxim) to 2.38 (Isostar) and therefore were below the critical pH value (5.5) for enamel demineralisation. Both Lucozade varieties had high titratable acidities (16.30 ml 0.1M NaOH to neutrality) with Gatorade, High Five, and Isostar displaying intermediate titratable acidity, although Isostar had 74.5 ppm calcium and 63.6 ppm phosphate. The fluoride concentration of all drinks was low, and none of the drinks was particularly viscous (range 3.1-1.4 mPa.s). CONCLUSIONS: The chemicophysical analyses indicate that all the sports drinks in this study have erosive potential. However, drinks with higher pH, lower titratable acidity, and higher concentrations of calcium, phosphate, and fluoride will reduce this erosive potential.- - - - - - - - - - ranking = 2keywords = physical (Clic here for more details about this article) |
