11/87. Enhanced post crown retention in resin composite-reinforced, compromised, root-filled teeth: a case report. The introduction of an intraradicular composite reinforcing technique, in conjunction with the reestablishment of matching post canal spaces, has allowed compromised, root-filled teeth to be restored with functional, esthetic post crowns. This clinical case report suggests that reconstituted post canals, in accurately adapting to passive, parallel-sided, matching, and well-fitting posts, can enhance the retention of post crowns. Other factors of clinical importance relating to the resin-reinforced technique are discussed, including fracture resistance, depth of polymerization, dentin adhesion, polymerization shrinkage, and coronal microleakage.

12/87. Nonvital tooth bleaching: a 2-year case report. A discolored, nonvital maxillary right central incisor was bleached with sodium perborate and water, used as a "walking" bleach. An excellent result was obtained, proving the efficiency of both the intracoronal bleaching technique and the materials employed. A clinical evaluation performed 2 years later revealed that the tooth was slightly stained but esthetically satisfactory. ( info) |
13/87. A cautionary tale. Case report. A healthy 26 year old female underwent unsuccessful surgery for an incorrectly diagnosed sebaceous cyst in the cheek. Eventually the problem was traced to a non-vital tooth 24. When the tooth was treated endodontically, the situation resolved in one week. ( info) |
14/87. Root extrusion, a practical solution in complicated crown-root incisor fractures. Implants and fixed and removable prostheses are very successful in replacing missing units but their cost can be inhibitory to a number of patients. In addition fixed and removable prostheses can be destructive to sound abutment teeth and can result in damage to dental and soft tissue. This report describes the restoration of a tooth with a complicated incisor crown-root fracture that extended below both the gingival cuff and the alveolar crest, by using remaining tooth tissue. The restoration was completed after root extrusion with a cast post, diaphragm and core, and porcelain crown. ( info) |
15/87. Use of an existing post to rerestore an endodontically treated tooth with a new post-and-core complex and crown: a case report. Replacement of a post-and-core restoration that has failed because of caries or fracture presents a restorative challenge to the general dentist. This case report describes a new technique that enables the utilization of an unremovable preexisting post in the fabrication of a new post-and-core complex. This complex served as a foundation for a restoration that restored form and function to the patient's dentition. ( info) |
16/87. Implant failures associated with asymptomatic endodontically treated teeth. BACKGROUND: Endosseous root-formed implants occasionally fail to osseointegrate. Causes of failure include infection, overheating of the bone, habitual smoking, systemic disease, transmucosal overloading, excessive surgical trauma and implant placement adjacent to teeth demonstrating periapical pathology. CASE DESCRIPTION: In this article, the authors present another possible cause of implant failure. The cases of four patients who received endosseous root-formed implants are discussed. Each patient demonstrated signs of infection after initial implant placement. The common factor in each failing implant was its placement adjacent to an asymptomatic endodontically treated tooth with no clinical or radiographic evidence of pathology. CLINICAL IMPLICATIONS: These patients demonstrate the importance of evaluating and possibly retreating or extracting adjacent endodontically treated teeth before placing implants. ( info) |
17/87. Treatment of cariously involved fused maxillary primary lateral and central incisors. A 3-and-a-half-year-old male child presented with fused cariously involved right maxillary primary central and lateral incisors as well as a previously traumatized non-vital left primary central incisor with a draining fistula. The child also had other restorative needs and the decision taken was to address all needs under a G.A. With respect to the fused incisors, these were split and root canals treatment was performed for all three incisors which were then restored with stainless steel crowns with esthetic facings.

| maxillary sinusitis can cause pain or discomfort to the maxillary dentition but no report of patients complaining of a "jumping tooth sensation" during sinusitis has been recorded in the literature. This article presents a case of an unusual localised sensation from a maxillary right second premolar experienced while undergoing root canal treatment. This sensation was felt during walking while the patient was suffering an episode of influenza. This sensation first occurred following debridement of the root canal. However, it persisted even after the root canal had been sealed. A hypothetical explanation of this manifestation is proposed. ( info) |
19/87. Pyogenic granuloma subsequent to apical fenestration of a primary tooth. BACKGROUND: The authors present two case reports of patients exhibiting pyogenic granulomas in the maxillary labial mucosa, which were related to an apical fenestration of a primary incisor. CASE DESCRIPTIONS: Several researchers have reported that the gingival wound and surrounding inflammatory tissue typically heal spontaneously after extraction of a fenestrated primary tooth. However, in the cases presented here, the gingival lesion did not heal after the fenestrated teeth were extracted. CLINICAL IMPLICATIONS: After extracting fenestrated teeth, clinicians need to examine the labial area at a follow-up appointment to ensure that the gingival hyperplasia heals properly. The authors suggest performing curettage of the surrounding abnormal tissue at the time of the tooth extraction. ( info) |
20/87. Submerging an endodontically treated root to preserve the alveolar ridge under a bridge--a case report. The loss of teeth results in the resorption of the residual alveolar ridges. This case report describes the successful maintenance of the alveolar ridge contour in the maxillary anterior region under a fixed prosthesis by the mucosal coverage and submersion of an endodontically retreated root, including a 6-year follow-up.
