1/9. 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.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/9. Treatment selection for anterior endodontically involved teeth.Innovations in material science and clinical techniques have expanded the number of treatment options available for nonvital anterior teeth. These options include the use of composite to fill the access opening with no additional treatment, crown placement, orthodontic extrusion, crown lengthening with or without orthodontic extrusion, dowel restorations with crown placement, and fixed bridge or implant therapy when extraction is necessary. Clinicians need to understand the benefits and limitations of each option in order to provide their patients with optimum function and aesthetics. Using case presentations, this article describes predictable approaches for the diagnosis, treatment planning, and restoration or replacement of endodontically treated teeth in the anterior region.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
3/9. Management of endodontic failures: case selection and treatment modalities.General dentists should realize that endodontic failures can be retreated successfully, avoiding tooth loss. retreatment of endodontic failure and initial root canal therapy share similar biologic principles and treatment objectives. The criteria for successful root canal therapy are important factors that must be understood before teeth are retreated. This article demonstrates three retreatment modalities for managing endodontic failures as an alternative to tooth extraction.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
4/9. The effects of periradicular inflamation and infection on a primary tooth and permanent successor.Primary teeth and the permanent successors must be understood as interdependent units, where each one of them interacts with and depends on each other. Pulpal inflammation/infection of a primary tooth and the spread of this condition over the periradicular tissues can lead to alterations in the dental germ of the permanent successor and to the surrounding structures if no therapy is done, i.e. endodontics or extraction. This work will present cases of permanent teeth that showed alteration in eruption and / or in development, as a consequence of inflammation / infection of the preceding primary teeth, such as: hypoplasia, morphological alteration on the dental crown or total arrest of. radicular formation. The teeth analysed in this study belong to patients who attended the Universidade Federal de Santa Catarina Children's dentistry Clinic. The earlier these lesions are diagnosed, the less were the destructive effects and the consequences on the primary tooth/permanent germ unit.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
5/9. Three-dimensional, non-destructive visualization of vertical root fractures using flat panel volume detector computer tomography: an ex vivo in vitro case report.AIM: To detect and to visualize radiographically vertical root fractures in extracted teeth with a prototype of a novel, high resolution, three-dimensional flat panel volume detector computer tomograph (FD-VCT) system. SUMMARY: Five teeth with root fillings and clinical symptoms such as fistulas and isolated periodontal pockets of 8 mm or more were extracted after dental radiography indicating lateral or periapical lesions. Vertical root fractures or cracks were suspected because of the symptoms and clinical findings were evident after extraction in all cases but fracture lines were not visible on routine dental radiographs acquired before extraction. The extracted teeth were explored with a prototype of a FD-VCT. Using the FD-VCT, in all cases vertical root fractures or crack lines could be detected clearly in different views, depiction-modes and cross-sections at a spatial resolution of 140 microm. The evaluation of the fracture lines and teeth could be performed in three-dimensional views. The FD-VCT findings were confirmed by detailed inspection of the extracted teeth. KEY learning POINTS: The FD-VCT is an innovative diagnostic tool for non-destructive, three-dimensional evaluation of extracted teeth in pre-clinical and experimental studies. The FD-VCT allows precise visualization and evaluation of vertical root fractures or cracks in extracted teeth. Clinical application of the system may be possible if technical modifications reduce the exposure dose: the high resolution detector systems of the FD-VCT should be combined with radiation systems that focus the radiation to the area of interest.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/9. Histological observations of periradicular healing following root canal treatment.The purpose of this study was to observe histologically the sequence of events leading to resolution of periradicular tissues, with a view to advancing the perception of periapical healing. Our material consisted of periapical specimens obtained from 15 single-rooted, endodontically treated teeth of patients aged 25-40 years. All the teeth required extraction because of complicated crown-root fracture following trauma, iatrogenic aetiology (cervical root resorption following bleaching) or extensive carious lesions. The patients were informed that, based on their clinical condition, surgical procedures should be performed under flap reflection in order to extract the fractured root. informed consent, which was necessary for the surgery, was obtained in all cases. A small block section containing the apical root tip and surrounding periapical tissues was removed prior to root extraction. The results of histological examination revealed osteoblastic activty and osteoid bone formation six days after the root canal instrumentation. periapical tissue healing was observed despite the presence of overfilled material. The lining epithelium was infiltrated with chronic inflammatory cells and surrounded by collagen bundles and newly formed bone.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/9. Acquired toxoplasmosis of a submandibular lymph node in a 9-year-old boy diagnosed by fine-needle aspiration cytology.toxoplasmosis is a parasitic infection which may be asymptomatic or produce lymphadenopathy, fever and malaise. In children the cervical lymph nodes are most commonly affected. This report describes a case of a 9-year-old boy who presented with submandibular lymphadenopathy associated with a non-vital primary tooth, which persisted following extraction of the tooth. A diagnosis of acquired toxoplasmosis was made on the findings of fine-needle aspiration cytology and subsequently confirmed by serological investigations, thus sparing the patient unnecessary hospitalization and surgery. The patient required amitryptyline as a nocturnal sedative and made a complete recovery within a few months without the need for further intervention.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
8/9. Forceps extraction of teeth with severe internal root resorption.Many treatment plans require a dental practitioner to maintain the entire labial cortical plate of bone when removing an anterior maxillary tooth. A tooth with an undermined root secondary to an endodontic perforation or internal (Idiopathic) resorption can present a surgical challenge to the general practitioner. This article describes a new technique for extracting a severely undermined anterior maxillary tooth while maintaining the entire labial cortex of bone.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
9/9. Vertical root fractures in adjacent maxillary premolars: an endodontic-prosthetic perplexity.Vertical root fractures in endodontically treated teeth occur frequently in teeth or roots in which their mesiodistal dimension is narrow, such as the maxillary upper premolars. Two cases of vertical root fractures in two adjacent maxillary reconstructed teeth are presented. As in many cases of vertical root fractures, the primary diagnosis was of endodontic treatment failure. The final diagnosis of the fractures was made either by the radiograph showing separation of root segments in one case, or by surgical exploration in the other. In both cases, tooth extraction was unavoidable.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
