1/56. Root canal treatment of a root-fractured incisor tooth with internal resorption: a case report. A case is described in which root canal treatment with calcium hydroxide was used successfully to repair a fracture site with internal resorption of the tooth. ( info) |
2/56. Dentinal dysplasia type I: report of a case. A case of dentinal dysplasia type I is presented. This rare hereditary disturbance of dentine is characterized by short-rooted teeth with sharp conical apical constrictions, aberrant growth of dentine in the pulp chamber leading to reduced pulp space in permanent teeth and total pulpal obliteration in the primary dentition. Clinical, radiographic and histopathological material from a 7-year-old boy, showing the typical features of this disorder in which teeth are prematurely lost through periapical abscesses, cysts or spontaneous exfoliation, is described. A review of the theories of pathogenesis of this condition is included. Management of patients with dentinal dysplasia is difficult and a discussion of the shortcomings of various treatment strategies, including conventional endodontic therapy, periapical curettage and retrograde root filling, and a preventive regimen, are discussed. In this case, despite diagnosis being made at an early age and the provision of regular dental care, the patient is now losing teeth because of spontaneous abscess formation. ( info) |
3/56. Pulp stones throughout the dentition of monozygotic twins: a case report. Pulpal calcifications are relatively common. However, their occurrence in the entire dentition is relatively infrequent. The presence of such calcification arouses suspicion of systemic or hereditary origin. This case report describes twin sisters with pulpal calcifications in their entire dentitions. No systemic cause was detected. The pattern of calcification was partially consistent with the hereditary condition of dentinal dysplasia. ( info) |
4/56. Combined treatment of a large periodontal defect using GTR and DFDBA. The regeneration of periodontal structures lost to inflammatory disease is an elusive yet attainable goal of periodontal therapy. This article reports the successful treatment of a large periodontal defect using a combination of demineralized freeze-dried bone allograft (DFDBA) and guided tissue regeneration (GTR). The case presents endodontic and mucogingival complications in the combined GTR osseous graft technique. The combined techniques used in this 27-year-old patient achieved a reduction in probing depth, radiographic evidence of bone fill, and a reduction in clinical mobility. ( info) |
5/56. Whitening of endodontically untreated calcified anterior teeth. Definitive treatment for whitening endodontically untreated anterior teeth with dystrophic calcification is provided by removing the coronal sclerotic dentin and utilizing internal and external bleaching as necessary. ( info) |
6/56. Bone-like tissue growth in the root canal of immature permanent teeth after traumatic injuries. Following a severe traumatic incident to permanent immature teeth, the growth of calcified tissue in the pulp space may occasionally occur. This calcified tissue may be diffuse or in intimate contact with the dentine. It has been suggested that a wide open apex, severe damage to the root sheath, and the absence of infection are only some of the predisposing factors leading to this metaplasia of pulp tissue into bone-like tissue. Five cases are described. ( info) |
7/56. Trauma quiz. Terribly troublesome, trauma teeth. Unfortunately, we come across many traumatised teeth during our practising career. Some of these traumatic injuries are rather simple to treat whereas others provide us with a real challenge. It is absolutely essential that the diagnosis of the injury be known before any treatment is attempted. When it comes to trauma, however, defining the exact form of treatment can often be very difficult. In this paper I will discuss some of the cases that I have managed and leave it up to YOU to decide whether my treatment has been correct, incorrect or whether there is some other form of treatment that we have at our disposal that could have been attempted.

8/56. Bur extensor for root canal access. Access to a tooth with a partial canal calcification was made. The access was possible only with a bur extensor connected to a LN bur. Calcification was bypassed, and the canal was completely prepared. ( info) |
9/56. Otodental syndrome: a case report and genetic considerations. A 5-year-old boy presented with otodental syndrome. His maxillary and mandibular incisors were within normal limits. The premolar/molar areas in all quadrants were occupied by markedly macrodontic teeth showing globular shape. The canines had a similar rounded shape. Two canines and 1 of the other abnormal teeth demonstrated areas of yellow hypoplastic enamel. Radiographs revealed that some of the abnormal teeth had bifurcated pulp chambers and pulp stones. Premolar tooth germs were absent. audiometry demonstrated that the child had a marked bilateral sensorineural hearing loss for frequencies above 1000 Hz. No other members of the immediate family were clinically affected. The parents of the child were not aware of any similarly affected relatives. Suggestions with respect to possible genetic mechanisms and gene participation in the etiology of this syndrome are offered. ( info) |
| dermatomyositis is a rare disease of unknown origin, which affects both children and adults. In the juvenile form, dermatomyositis is a multisystem disease, characterized by myositis; an erythematous rash over the bridge of the nose, around the eyes, and on the trunk and limbs; vasculitis; and dilatation of the capillaries in the nail beds and gum margin. Late development of calcinosis is seen in approximately two-thirds of the patients. This case describes a 5-year-old dental patient diagnosed with dermatomyositis. This article includes the clinical manifestations of dermatomyositis in the body and in the oral cavity as well as the considerations that should be taken when treating these patients. ( info) |
