1/11. microbiology of subgingival plaque from children with localized prepubertal periodontitis.Localized prepubertal periodontitis has been described as a host-defect mediated form of bacterially induced periodontitis, with an early onset and rapid progression around a few teeth in children prior to puberty. To further our understanding of the etiology of this disease, we have examined the microbiological components of subgingival dental plaque in 9 children with localized prepubertal periodontitis to determine if patterns of putative pathogens existed, and have compared these results with those obtained from 4 children with no periodontitis. Subgingival plaque samples were plated onto a selective medium for actinobacillus actinomycetemcomitans and onto a non-selective medium for anaerobes, and the predominant cultivable microbiota of 2 sites per child was determined. The subgingival microbiota of children with localized prepubertal periodontitis clearly differs from non-diseased children in the detection of high levels of several suspected pathogens, including A. actinomycetemcomitans, bacteroides intermedius, eikenella corrodens, and capnocytophaga sputigena. These putative pathogens were found in various combinations. These findings suggest that localized prepubertal periodontitis is associated with specific subgingival bacteria which are generally not found in children without periodontitis.- - - - - - - - - - ranking = 1keywords = progression (Clic here for more details about this article) |
2/11. Dynamics of dental implants and orthodontics in today's periodontal prosthesis.periodontal prosthesis refers to multidisciplinary efforts to stop disease progression, correct deformities created by dental diseases, and establish a therapeutic occlusion to restore the form and function of the masticatory system. These efforts are critical for the long-term prognosis and maintenance of the guarded teeth and the overall prosthesis. This article presents a functionally and esthetically challenging case, which illustrates a multidisciplinary approach--specifically implantology and orthodontics--and how they impact on each other during treatment. The role and importance of dental implants and orthodontics in setting up a case is illustrated in this article.- - - - - - - - - - ranking = 177.75164556116keywords = disease progression, progression (Clic here for more details about this article) |
3/11. Complications associated with diabetes mellitus after guided tissue regeneration--a case report revisited.Twelve to fourteen million individuals suffer from diabetes mellitus (DM), though the disease is undiagnosed in a large number of these people. dentists must be aware of the signs and symptoms of DM so they can better manage the treatment of whatever dental therapy their patients with diabetes require. DM has been reclassified into type 1 and type 2, based on the individual's insulin requirements. The diabetic patient may present with, or develop, advanced periodontal disease, which may be more difficult to control because of metabolic status and commitment to dental care. This article includes a description of a type 2 diabetic who reportedly was well controlled, yet experienced complications after guided tissue regeneration. The postsurgical results were acceptable and the patient remained stable during supportive periodontal therapy. However, she became noncompliant with her dental care and converted from a type 2 to a type 1 diabetic with poor control. The case illustrates the rapid progression of periodontal disease in a side that had been successfully treated. It also discusses the interrelationships between diabetes and periodontal disease.- - - - - - - - - - ranking = 1keywords = progression (Clic here for more details about this article) |
4/11. 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 = 1keywords = progression (Clic here for more details about this article) |
5/11. Barrier membrane and bone graft treatments of dehiscence-type defect at existing implant: a case report.Dehiscence-type bony defects may occur after implant application because of microbial action as well as of biomechanical and occlusal overload. The aim of the treatment of a periimplant defect is to arrest the progression of the bone loss and to achieve a maintainable site for the implant. In these situations, barrier membranes and bone graft materials can be used to achieve complete bone healing around dental implants. bone regeneration is possible in a periimplant bony defect of a functioning implant if the proper surgical technique is utilized and the etiologic cause is eradicated. This study presents the surgical coverage of a periimplant bony defect around an implant that was inserted 7 years ago. The surgical correction was made using a barrier membrane in conjunction with bone graft materials. A follow-up of 6 months seemed to reveal radiographic bone regeneration.- - - - - - - - - - ranking = 1keywords = progression (Clic here for more details about this article) |
6/11. Periodontal management of an adolescent with Down's syndrome--a case report.A case of periodontitis in a young adolescent Japanese girl with Down's syndrome is presented in this report. The patient received a monthly preventive course of dental care consisting of mechanical plaque control and oral hygiene instruction. After 2.5 years she recovered from progression of periodontal disease both clinically and microbiologically. The importance of clinical care for periodontitis in Down's syndrome patients is discussed.- - - - - - - - - - ranking = 1keywords = progression (Clic here for more details about this article) |
7/11. Localized aggressive periodontitis in a six-year-old: a case report.The purpose of this report was to describe an approach to diagnose and effectively treat a pediatric patient with localized aggressive periodontitis. A 6-year-old female presented with clinical and radiographic evidence of severe attachment loss around several primary teeth. She had no history of systemic disease, periodontal disease, or caries prior to the periodontal abscess that prompted her referral. Routine immunological tests did not reveal any functional defects, but dna testing for periodontal pathogens revealed the presence of all 8 aggressive periodontal pathogens assayed. Treatment consisted of the extraction of 2 severely affected primary teeth, increased frequency of recall appointments, and administration of systemic antibiotics. The patient's periodontal condition was stabilized 18 months post-treatment, and the 8 pathogens were no longer at detectable levels. With a treatment goal of preventing disease progression into the erupting permanent dentition, this treatment regimen provides an effective alternative to more aggressive strategies.- - - - - - - - - - ranking = 177.75164556116keywords = disease progression, progression (Clic here for more details about this article) |
8/11. Gorham's disease of the mandible mimicking periodontal disease on radiograph.BACKGROUND: Gorham's disease is a rare disorder characterized by spontaneous and progressive osteolysis of one or more skeletal bones. The radiographic findings associated with Gorham's disease are particularly dramatic, as in some cases a complete resorption of the involved bone can occur, leading to the definition of phantom bone, vanishing bone, or disappearing bone disease. MATERIAL AND methods: A 24-year-old female patient with a previous diagnosis of periodontal disease and progressive mandibular alveolar bone loss was referred to our oral medicine section. The initial radiographic picture showed infrabony defects and horizontal bone loss. RESULTS: After further extensive local and systemic evaluation, including histopathological, laboratory and imagine techniques investigations, the patient was diagnosed to be affected by Gorham's disease. Meanwhile the progression of the osteolytic process had caused the loosening of all the left mandibular teeth and a pathologic fracture. Appropriate medical therapy was successful in stabilizating the resorptive process, with no evidence of further progressive disease. CONCLUSIONS: When Gorham's disease involves the mandible, the role of the periodontologist is extremely important in diagnosing promptly the disorder and preventing the functional and aesthetic consequences of advanced and extensive bone loss. Gorham's disease should be included among the pathologic entities mimicking periodontal disease on radiograph, such as inflammatory disease (e.g. osteomyelitis), endocrine disease (e.g. hyperparathyroidism), intra-osseous malignancies or metastases, lymphoma, histiocytosis X, mainly eosinophilic granuloma, infective process (e.g. tuberculosis and actinomycosis), odontogenic tumours.- - - - - - - - - - ranking = 1keywords = progression (Clic here for more details about this article) |
9/11. aggressive periodontitis in a 16-year-old Ghanaian adolescent, the original source of actinobacillus actinomycetemcomitans strain HK1651 - a 10-year follow up.The highly leukotoxic JP2 clone of actinobacillus actinomycetemcomitans is strongly associated with periodontitis in adolescents. Availability of the dna sequence of the complete genome of A. actinomycetemcomitans strain HK1651, a representative strain of the JP2 clone (http://www.genome.ou.edu/act.html), has provided new possibilities in basic research regarding the understanding of the pathogenesis of A. actinomycetemcomitans in periodontitis. This case report describes the periodontal treatment of the original source of A. actinomycetemcomitans HK1651, a 16-year-old Ghanaian adolescent girl with aggressive periodontitis. The bacterial examination involved polymerase chain reaction analysis for presence of JP2 and non-JP2 types of A. actinomycetemcomitans. The treatment, including periodontal surgery supplemented by antibiotics, arrested the progression of periodontitis for more than 10 years. Initially, infection by A. actinomycetemcomitans, including the JP2 clone, was detected at various locations in the oral cavity and was not limited to the periodontal pockets. Post-therapy, the JP2 clone of A. actinomycetemcomitans disappeared, while the non-JP2 types of A. actinomycetemcomitans remained a part of the oral microflora.- - - - - - - - - - ranking = 1keywords = progression (Clic here for more details about this article) |
10/11. Progressive osseous destruction as a complication of hiv-periodontitis.A pathologic condition is described, characterized by rampant necrosis of gingival mucosa, periodontium, and related osseous structures associated with systemic infection with the human immunodeficiency virus (hiv). It is believed that this condition is an extension beyond the normal clinical course of hiv-periodontitis (hiv-P) and manifests itself in three progressive stages: (1) hiv-associated gingivitis, (2) hiv-P, and (3) an extension of hiv-P to osseous necrosis. Two cases of osseous destruction attending hiv-P are reported, one of which led to initial diagnosis of hiv infection. They represent the final stage of disease progression with localized necrosis of gingiva, periodontium, and alveolar bone.- - - - - - - - - - ranking = 177.75164556116keywords = disease progression, progression (Clic here for more details about this article) |
