1/18. Treatment of invasive cervical resorption: an analysis of results using topical application of trichloracetic acid, curettage, and restoration.OBJECTIVE: The purpose of this study was to carry out a clinical evaluation of the treatment of invasive cervical resorption. METHOD AND MATERIALS: Topical application of a 90% aqueous solution of trichloracetic acid, curettage, nonsurgical root canal treatment where necessary, and restoration with glass-ionomer cement were performed on 94 patients with a total of 101 affected teeth. A minimum of 3 years' follow-up was required, unless failure occurred before that time, in which case that treatment was included. Teeth were divided into four classes, depending on the extent of the resorptive process. Class 1 represented the least invasive resorptive lesion, near the cervical area with shallow penetration into dentin, while class 4 represented the most invasive resorptive process, which had extended beyond the coronal third of the root. RESULTS: In all class 1 and class 2 cases, the results showed complete success, judged by an absence of resorption or signs of periapical or periodontal pathosis. When overall success was judged by absence of resorption and periapical or periradicular pathosis, the success rate in class 3 lesions was 77.8%. Only 12.5% of teeth in class 4 were free of resorption and deemed to be clinically sound. CONCLUSION: The treatment regimen was successful in class 1 and class 2 cases, reasonably successful in class 3 cases, and generally unsuccessful in class 4 resorptions, where alternative treatment is recommended. diagnosis of lesions at an early stage is, therefore, highly desirable.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
2/18. Deposition of calcified tissue around an overextended gutta-percha cone: case report.CASE REPORT: Root canal treatment was performed in a mandibular right second premolar with a periapical lesion and apical resorption. The root canal was prepared with K-files using the step-back technique and 3% NaOCl as an irrigant; during obturation gross overfilling of gutta-percha occurred. The tooth was permanently restored with a post and core along with a crown. Although healing of the periapical lesion occurred and the patient reported that he was symptom-free, the tooth was extracted after 4 years because of a subgingival root fracture. Following extraction the tooth was examined with SEM. The examination revealed the presence of newly formed calcified tissue at resorption sites on the root apex. This newly formed tissue extended from the surface of the root around the apex to the extruded gutta-percha cone to which it was well adapted, forming a bridge between the cone and the root.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
3/18. root resorption and signs of repair in Papillon-Lefevre syndrome. A case study.The aim of this investigation was to describe some tooth-related histological features of prepubertal periodontitis. Teeth extracted during treatment of two Papillon-Lefevre syndrome patients were processed by means of the sawing and grinding technique. light microscopy examination revealed little or no cementum in the coronal parts of the roots. Resorptions of various depths (0.02 to 1.5 mm) and to various extents (affecting up to 1/3 of the root surface) were observed in the 5 investigated teeth. Some resorptive defects on 1 of the examined incisors showed signs of spontaneous repair. Extrinsic fibers were inserted into the new cellular intrinsic fiber cementum which had formed directly on the bottom of the defect. Intact acellular extrinsic fiber cementum was found where fibers were still attached. Here, the characteristic of pristine cementum, a hyaline layer of peripheral dentin, could be identified. If resorption was not present, the cementum did not show any signs of hypoplasia. Thus, histological features of prepubertal periodontitis in the current material were (i) areas of extensive resorption, (ii) signs of spontaneous repair, and (iii) healthy cementum.- - - - - - - - - - ranking = 2.9179943764679keywords = periodontitis (Clic here for more details about this article) |
4/18. Treating internal resorption using a syringeable composite resin.BACKGROUND: Internal resorption is a pathological process initiated within the pulp space with the loss of dentin. It often is described as an oval shaped enlargement of the root canal space and usually is asymptomatic and detectable by routine radiographs. Treatment of internal resorption has included several materials--gutta-percha, zinc oxide eugenol and amalgam alloy. These materials do not provide strength to the tooth structure. CASE DESCRIPTION: A 29-year-old woman was referred to a dental clinic for treatment of a large internal resorptive defect in the coronal and middle one-third of the maxillary left central incisor root with no apparent periapical pathosis, as well as a large periapical radiolucency at the apex of the maxillary left lateral incisor that was associated with a necrotic pulp. The authors used a dual-cure syringable composite resin in conjunction with a bonding agent within the defect to treat it. CLINICAL IMPLICATIONS: This technique seals the dentinal tubules and strengthens the remaining tooth structure. It also improves the outcome of resorptive defects and reduces operators' chair time.- - - - - - - - - - ranking = 1keywords = periapical (Clic here for more details about this article) |
5/18. 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 = 1.4589971882339keywords = periodontitis (Clic here for more details about this article) |
6/18. Ehlers-Danlos type VIII. review of the literature.Ehlers-Danlos type VIII is a rare disorder characterized by soft, hyperextensible skin, abnormal scarring, easy bruising, and generalized periodontitis with early loss of teeth. To illustrate the clinical dermatological and dental features, we present the case history of a 20-year-old patient who has suffered from poor healing of wounds at the shins and knees since childhood, which have developed into hyperpigmented atrophic scars. In the course of orthodontic treatment during the last 3 years, severe apical root resorption, gingival recession, and loss of alveolar bone were observed. family history was noncontributory for any skin or tooth disorders. The typical clinical signs confirmed the diagnosis of ehlers-danlos syndrome type VIII. As there is no specific treatment for the disorder, management is limited to the symptomatic treatment of the dental disease. It seems advisable to consider carefully the indications for orthodontic treatment in patients with Ehlers-Danlos type VIII syndrome.- - - - - - - - - - ranking = 1.4589971882339keywords = periodontitis (Clic here for more details about this article) |
7/18. The horizontally impacted maxillary canine situated in a labial position.Surgical management of unerupted teeth depends upon a thorough understanding of anatomic, physiologic and pathologic factors. attention has been given to problems of eruption in the maxillary anterior region. It is a region where a variety of anomalies occur. Since the maxillary anterior region influences appearance so greatly, early detection of difficulties and careful planning and treatment can be extremely beneficial to patients. The purpose of this case report is to present a case of maxillary permanent canine impaction in a horizontal displacement that developed after loss of the deciduous canine to chronic apical periodontitis, and incomplete root resorption of the deciduous canine.- - - - - - - - - - ranking = 1.4589971882339keywords = periodontitis (Clic here for more details about this article) |
8/18. Prepubertal periodontitis: a report of 2 cases.PURPOSE: Prepubertal periodontitis is a term suggested for a form of periodontitis that starts soon after the eruption of primary teeth. There is increased awareness that the disease entity known as "periodontitis" is in all probability a family of related but reasonably discrete diseases. The purpose of this report is to describe the clinical, radiographic, and laboratory findings in 2 patients, as well as treatment of prepubertal periodontitis. methods: This study presents 2 cases of generalized prepubertal periodontitis: a 5-year-old girl and a 13-year-old girl. RESULTS: Case 1 presented to the clinic because of parental concern for the early exfoliation of her teeth. All of her teeth with Grade III mobility, ie, 8.5, were extracted and the rest were scaled and root planed with subgingival irrigation of 0.2% chlorhexidine. She received a program of 3-month maintenance scaling and 6 months later, there was no further progression of periodontal lesions. Case 2 demonstrated the destruction of tooth roots along with extensive loss of tooth roots and alveolar bone. Since all the permanent teeth were Grade II mobile, the patient was advised to have total extraction with replacement of teeth by complete denture prosthesis at a later date. CONCLUSIONS: In case 2 premature root resorption was occurring concurrently with unexplained extensive alveolar bone loss. In Case 1, the elimination of the pathogenic microflora during primary dentition by early extraction of the teeth involved, plus daily local, mechanical and chemical control of the irritant factors may have prevented subsequent damage to remaining teeth in prepubertal periodontitis.- - - - - - - - - - ranking = 14.589971882339keywords = periodontitis (Clic here for more details about this article) |
9/18. Radiographic examination of dentigerous cysts in the transitional dentition.OBJECTIVES: To examine radiographically the relationship between the deciduous tooth and dentigerous cyst of the permanent successor during the transitional dentition. methods: From a retrospective review of all patients who visited our institution from April 1988 to August 2001, 70 patients under 16 years of age who had histologically confirmed dentigerous cysts that had developed from the central incisor to the second premolar were identified. These 70 patients were investigated using panoramic and periapical radiographs. RESULTS: In most cases (54 cases; 77.1%) the cyst was in the premolar region. Of the 54 premolars with dentigerous cysts, the overlying deciduous tooth had already been lost in 7 cases. Of the 47 remaining premolars with associated deciduous tooth, 35 (74.5%) had bone resorption of the periapical or bifurcation region, or irregular resorption of the associated deciduous tooth. Of the remaining 12 deciduous teeth with no periapical lesions, 9 had been treated with root canal therapy. Thus, 44 of these 47 cases (93.6%) had the possibility of inflammation at the deciduous tooth associated with the dentigerous cyst. Evidence from one case in the present study suggesting the process by which cyst development occurs is also given. CONCLUSION: Inflammatory change at the apex of the deciduous tooth may bring on a dentigerous cyst of the permanent successor.- - - - - - - - - - ranking = 1.5keywords = periapical (Clic here for more details about this article) |
10/18. Treatment of avulsed teeth with Emdogain--a case report.The present case report describes the reimplantation of avulsed teeth with the treatment of Emdogain. Case was avulsed right maxillary permanent central and lateral incisor in a 9-year-old girl suffering from a traumatic injury. After pretreatment of avulsed teeth, Emdogain was applied to the root surface and into the extraction socket with subsequent replantation of the tooth. Evaluation parameters included horizontal and vertical percussion sound and periapical radiographs. At 1-2-6-12-month follow-up period, the clinical and radiographic appearance of the teeth showed resolution of mobility and no signs of replacement resorbption.- - - - - - - - - - ranking = 0.5keywords = periapical (Clic here for more details about this article) |
