1/74. Focal malakoplakia in chronic periapical periodontitis.AIMS: Three cases of chronic periapical periodontitis including focal areas with malakoplakia changes are reported. methods AND RESULTS: These areas included both von Hansemann-type macrophages and periodic acid-Schiff-positive, iron- and calcium-containing concretions. Some concretions corresponded to spherules with a targetoid configuration, thus fitting the morphological criteria for classical Michaelis-Gutmann bodies. CONCLUSION: The vast majority of the cases of malakoplakia that have been reported in the literature corresponded to a characteristic, fairly homogeneous lesion, but a few instances of focal malakoplakia have been described in various chronic conditions. These considerations support the opinion that the local conditions for the production of Michaelis-Gutmann bodies may occur focally in diseases characterized by macrophage accumulation.- - - - - - - - - - ranking = 1keywords = periapical periodontitis, periapical, periodontitis (Clic here for more details about this article) |
2/74. A case of an odontogenic cutaneous sinus tract.CASE REPORT: A 22-year-old female presented with a draining sinus tract on her left cheek. The tooth responsible was examined clinicopathologically. On clinical examination, the mandibular left first molar tooth was restored with an amalgam filling. Radiographic examination revealed base or pulp capping material below the restoration and a radiolucent periapical lesion surrounding the distal root apex. Conservative non-surgical root canal treatment was performed; 10 months later, the sinus had healed completely and the periapical lesion had resolved. Histopathological examination of pulp tissue recovered during treatment revealed foreign bodies, made up of capping material and amalgam, associated with chronic inflammation. These findings suggested that chronic inflammation in the pulp tissue had resulted in a draining sinus tract.- - - - - - - - - - ranking = 0.1342230343202keywords = periapical (Clic here for more details about this article) |
3/74. Successful treatment of pulpal-periodontal combined lesion in a birooted maxillary lateral incisor with concomitant palato-radicular groove. A case report.Palato-radicular groove (PRG) is a common developmental anomaly of maxillary incisors, whereas PRG associated with a birooted maxillary incisor is relatively infrequent. The clinical significance of PRG is related to the incidence of localized periodontitis with or without pulpal pathosis, depending on the depth, extent, and complexity of the groove. Successful treatments of PRG in single-rooted incisors have been reported in the literature. However, treatment of PRG in birooted incisors has often been ineffective. This case report describes a pulpal-periodontal combined lesion occurring on a birooted maxillary left lateral incisor with concomitant PRG in a 13-year-old boy which was successfully treated by conventional endodontic therapy in combination with periodontal treatment including accessory root resection, radiculoplasty and bone grafting. Seven-year follow-up is included in this report. The basis of a successful result is accurate diagnosis and elimination of inflammatory irritants and contributory factors. awareness of the existence of this abnormality by the clinician is important.- - - - - - - - - - ranking = 0.01427362066925keywords = periodontitis (Clic here for more details about this article) |
4/74. Repairing iatrogenic root perforations.BACKGROUND: Post preparation is an integral part of restoring endodontically treated teeth in indicated cases. Iatrogenic perforation of the root can result from preparing post space and can severely compromise the prognosis of the tooth. CASE DESCRIPTION: Two years after a patient's maxillary lateral incisor was restored with a post-retained composite resin, he went to a dental school emergency clinic with a chief complaint of soft-tissue swelling adjacent to the tooth. The authors took a periapical radiograph that revealed evidence of a circumscribed radiolucent lesion associated with the distal midroot area and a periapical radiolucency. Based on the radiograph, the authors suspected that the canal preparation for the post and the post placement had perforated the root at the base of the post. CLINICAL IMPLICATIONS: The authors used a combined surgical and orthograde approach with a biocompatible restorative material and a clear, plastic light-transmitting post to repair the iatrogenic perforation.- - - - - - - - - - ranking = 0.1342230343202keywords = periapical (Clic here for more details about this article) |
5/74. Delayed apical healing after apexification treatment of non-vital immature tooth: a case report.We report the endodontic treatment of a non-vital permanent immature tooth in which unexpected complications such as exacerbation of apical periodontitis followed by external root resorption occurred after that the initial stages of the healing process were clinically and radiographically evident. After continued treatment stable repair was obtained.- - - - - - - - - - ranking = 0.01427362066925keywords = periodontitis (Clic here for more details about this article) |
6/74. periapical abscess formation and resolution adjacent to dental implants: a clinical report.The vitality of teeth adjacent to dental implants should be considered in the treatment planning of dental implants. Both the restorability of an endodontically treated tooth and the risk of infection of the adjacent implant are important factors in planning for success. Given the illustrated difficulties and difficulties associated with resolving periapical infections of teeth and implants, it is essential to define the vitality of teeth by careful pulp testing and to consider the integrity of existing questionable, endodontically treated teeth before implant treatment. The risk of periapical infection at teeth adjacent to implants must be minimized.- - - - - - - - - - ranking = 0.13422407189868keywords = periapical, abscess (Clic here for more details about this article) |
7/74. 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.- - - - - - - - - - ranking = 0.067111517160101keywords = periapical (Clic here for more details about this article) |
8/74. Apparent periapical repair without operative intervention: a case report and discussion.CASE REPORT: A case is described where substantial reduction of an established periapical lesion appeared to take place in the absence of operative intervention, and as the crown of the tooth was progressively destroyed by dental caries. The case raises debate on the pathogenesis, diagnosis and monitoring of endodontic lesions, and may stimulate renewed research interest in these most fundamental elements of clinical endodontology.- - - - - - - - - - ranking = 0.3355575858005keywords = periapical (Clic here for more details about this article) |
9/74. Garre's osteomyelitis of an unusual origin in a 8-year-old child. A case report.Garre's osteomyelitis is a type of chronic osteomyelitis that primarily affects children and adolescents. Although the disease is well described in the dental literature and is usually associated with an odontogenic infection resulting from caries, a number of other causative factors have been occasionally reported, such as a dental extraction or a mild periodontitis. There have also been cases of unknown aetiology. This paper describes a case of Garre's osteomyelitis in an 8-year-old child, in whom the condition arose following a local periodontal infection in an ectopically erupting first permanent molar that was in infraocclusion. The lesion remained unresolved for a period of over 6 months as a result of misdiagnosis, following a number of unsuccessful treatment attempts. Identification of the true cause and treatment through periodontal surgery resulted in lesion resolution and resolved the diagnostic problem. dentists should be aware that the periodontium may be a potential source of infection for Garre's osteomyelitis in children, particularly in the presence of ectopically erupting posterior teeth. In such cases, periodontal treatment should be sufficient to treat the disease and extraction of the tooth involved may not be necessary.- - - - - - - - - - ranking = 0.01427362066925keywords = periodontitis (Clic here for more details about this article) |
10/74. The implant periapical lesion: four case reports and review of the literature.postoperative complications have been identified with implant failure in conjunction with the increased use of root-type implant restorations. The failure of osseointegrated dental implants primarily occurs as a result of peri-implantitis and occlusal overload. Less frequently reported failures, however, have been attributed to implant periapical lesions. The etiology and treatment modalities for such lesions have been speculated throughout the literature. This article discusses possible etiologies of and treatment for implant periapical lesions based on the existing literature and four case reports.- - - - - - - - - - ranking = 0.4026691029606keywords = periapical (Clic here for more details about this article) |
