1/13. Reattachment of a fractured maxillary incisor crown--case report.Management of traumatic injuries to the teeth is a challenge to the practising dentist. It has no prescriptive method for occurring, possesses no significant predictable pattern of intensity or extensiveness and occurring at times when dentists are least prepared for it. It may not only leave physical scars but also a psychological impact on its victim. Yet, more than half of all children traumatize either their primary or permanent teeth before leaving the school, coupled with the dynamic panorama of sporting activity worldwide and the significant increase in violence among the populations. Tooth trauma and its management loom as a major challenge to the dental practitioner. A case of a 11 year old boy with Ellis Class 3 traumatic injury to the maxillary left central incisor is reported. A pulpectomy was performed followed by reinforcement and reattachment of the crown fragment and restoration with composite resin.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/13. Unusual fracture of a mandibular second premolar: a case report.Root fractures of posterior teeth, which are defined as fractures involving cementum, dentin, and pulp, are relatively uncommon among dental traumas. This study describes an unusual horizontal fracture of a mandibular second premolar. The tooth was asymptomatic and the fracture unnoticed until the crown broke off completely. The patient had no recollection of a causative event nor was there any evidence of previous physical trauma. The tooth was extracted, embedded in resin, sliced, and examined with different light microscopes. It was concluded that the tooth had been damaged previously but not to the extent that the pulp was seriously damaged. Resorption over a period of time eventually caused the final fracture.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
3/13. Combined technique with polyethylene fibers and composite resins in restoration of traumatized anterior teeth.Traumatized anterior teeth need quick esthetic and functional repair. Esthetic requirements of anterior teeth require the use of composite materials which, in the most complex cases, can be used in association with fibers so as to improve their mechanical resistance. Many kinds of fibers are available. The authors considered parameters such as physical properties, water absorption, ease of cutting and of laying. polyethylene fibers appear to have the best properties in elasticity, translucency, adaptability, tenaciousness, resistance to traction and to impact. Fifteen children, between 7 and 13 years old, with crown fractures of the anterior sector were treated. In the case of a simple crown fracture, the missing part was restored by polyethylene fibers and composite resins. In the case of a complex crown fracture needing endodontic treatment, the fibers were used as a central core stump in order to restore the dental morphology. At control examinations, the teeth restored by this technique were acceptable, both in function and in aesthetics. Thus, the authors recommend this combined technique for predictable restoration of traumatized anterior teeth.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
4/13. Management of traumatic facial injuries.Whether minor or major, traumatic injuries to the maxillofacial area have far-reaching physical and emotional effects. Because the dentition dictates facial form and function, the oral and maxillofacial surgeon, a dental specialist with a minimum of four years of hospital-based surgical training, is uniquely qualified to manage these injuries. At times, the expertise of the general dentist and other dental specialists may be needed to provide definitive care. Several cases are provided to illustrate management of facial trauma.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
5/13. 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) |
6/13. Restoring the incisal edge.Restorative dentistry evolves with each development of new material and innovative technique. Selection of improved restorative materials that simulate the physical properties and other characteristics of natural teeth, in combination with restorative techniques such as the proximal adaptation and incremental layering, provide the framework that ensures the optimal development of an esthetic restoration. These advanced placement techniques offer benefits such as enhanced chromatic integration, polychromatism, ideal anatomical form and function, optimal proximal contact, improved marginal integrity and longer lasting directly placed composite restorations. The purpose of this article is to give the reader a better understanding of the complex restorative challenge in achieving true harmonization of the primary parameters in esthetics (that is, color, shape and texture) represented by the replacement of a single anterior tooth. The case presented demonstrates the restoration of a Class IV fracture integrating basic adhesive principles with these placement techniques and a recently developed nanoparticle hybrid composite resin system (Premise, Kerr/Sybron, Orange, CA). The clinical presentation describes preoperative considerations, tooth preparation, development of the body layer, internal characterization with tints, development of the artificial enamel layer, shaping and contouring, and polishing of a Class IV composite restoration. The clinical significance is that anterior tooth fractures can be predictably restored using contemporary small particle hybrid composite resin systems with the aforementioned restorative techniques. These placement techniques when used with proper attention to preparation design, adhesive protocol and finishing and polishing procedures, allow the clinician to successfully restore form, function and esthetics to the single anterior tooth replacement.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
7/13. Creating translucent edge effects and maverick internal tints using microhybrid resin.Today's composite resins possess optical and physical characteristics that have expanded their clinical indications. The successful and predictable application of these materials depends on the practitioner's understanding of their material properties as well as the clinical requirements involved in their delivery; identifying the characteristics of the natural tooth is also important. This presentation reviews contemporary resin materials and demonstrates simple and repeatable guidelines for margin and material placement that improve the clinician's ability to implement microhybrid resins in daily practice.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
8/13. 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) |
9/13. Clinical evaluation of two pinless incisal edge repairs: a 24-month study.Adhesive resin and composite resin were used to restore the central incisors in a 21-year-old woman at an emergency treatment. Two maxillary fractured incisors were restored (one after endodontic treatment) and reexamined over a period of 24 months (Fig 5). Some slight yellowing has been noted in the endodontically treated tooth, but it has not appreciably affected appearance. The patient did not object to the discoloration and no replacements or additions were done. The restorations showed no indications of excessive wear or physical damage during the examination period.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
10/13. Unusual fracture of a maxillary second premolar.Root fractures of posterior teeth are rare and occur as a result of severe trauma. This study describes a horizontal root fracture of a maxillary second premolar discovered during routine full-mouth radiographic examination. The tooth was asymptomatic and responded positively to electric pulp testing. The patient had no recollection of a causative event nor was there physical evidence of previous trauma. It is speculated that the fracture was caused when overzealous force was used in seating an overcontoured complete gold crown restoration of an adjacent tooth.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
