1/38. Tissue necrosis after subgingival irrigation with fluoride solution.Irrigation of periodontal pockets with fluoride solution after scaling and root planing is occasionally recommended to inhibit the growth of pathogenic bacteria in the periodontal pocket. At the same time, irrigation enables mechanical removal of loosely adhering plaque and debris. Due to its toxicity, fluoride solution deposited in the periodontium may lead to tissue damage. We report in this paper, a case of extensive periodontal tissue necrosis and permanent loss of alveolar bone after irrigation of periodontal pockets with stannous fluoride solution. The literature on the toxic effects of fluoride on the local tissues is briefly reviewed and arguments for a re-evaluation of the use of stannous fluoride for pocket irrigation are provided.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
2/38. Microbiological features of Papillon-Lefevre syndrome periodontitis.Papillon-Lefevre syndrome patients exhibit hyperkeratosis palmo-plantaris and severe periodontitis. The syndrome is an autosomal recessive trait, but the mechanism of periodontal destruction is not known. This report presents the clinical and microbiological features of an 11-year old girl with Papillon-Lefevre syndrome. Clinical examination included conventional periodontal measurements and radiographic analysis. In samples from 3 deep periodontal lesions, the occurrence of major suspected periodontopathic bacteria was determined by selective and non-selective culture and polymerase chain reaction (PCR) identification, and the presence of cytomegalovirus and Epstein-Barr type 1 virus by a nested-PCR detection method. 10 of 22 available teeth demonstrated severe periodontal breakdown. Major cultivable bacteria included actinobacillus actinomycetemcomitans (3.4% of total isolates), prevotella nigrescens (16.4%), fusobacterium nucleatum (14.3%) and peptostreptococcus micros (10.6%). A. actinomycetemcomitans, P. nigrescens, porphyromonas gingivalis and eikenella corrodens were identified by PCR analysis. The patient's non-affected parents and older brother revealed several periodontal pathogens but not A. actinomycetemcomitans. The viral examination demonstrated cytomegalovirus and Epstein-Barr type 1 virus in the subgingival sample of the Papillon-Lefevre syndrome patient. The father and brother yielded subgingival cytomegalovirus but not Epstein-Barr type 1 virus. We hypothesize that human herpesviruses in concert with A. actinomycetemcomitans play important roles in the development of Papillon-Lefevre syndrome periodontitis.- - - - - - - - - - ranking = 67360.945542921keywords = periodontitis (Clic here for more details about this article) |
3/38. Comparing periodontal disease in identical twins: a case report.Previous investigators have shown that numerous environmental and genetic variables may contribute to the pathogenesis of periodontal disease. This case report presents clinical and laboratory findings of a set of Caucasian female identical twins. One patient presented clinically with mild gingivitis and no clinical or radiographic signs of periodontitis. The other exhibited gingivitis with localized, moderate-to-severe periodontitis. Neither patient reported a history of systemic conditions that might influence their periodontal health, and neither presented other known risk factors, such as tobacco use. The only apparent variable was related to their oral hygiene. The periodontally involved patient exhibited higher plaque scores than her twin in all clinical visits. Subgingival plaque cultures revealed the presence of porphyromonas gingivalis and bacteroides forsythus only in the diseased twin. Both patients had low colony counts of prevotella intermedia and eikenella corrodens, but only the healthy twin harbored small quantities of fusobacterium nucleatum. This case report offers an opportunity to assess etiology of periodontitis in two genetically identical patients whose only obvious difference was their oral hygiene.- - - - - - - - - - ranking = 33680.472771461keywords = periodontitis (Clic here for more details about this article) |
4/38. The periodontal management of a patient with a profound immunodeficiency disorder.A case of severe, uncontrolled periodontal disease in a patient with a profound immunodeficiency disorder is reported. The periodontal disease was noted before the age of 10 years and is generalized, with marked associated alveolar bone loss, even threatening a mandibular fracture. Severely involved teeth were allowed to exfoliate, and extractions were avoided. At the age of 17 years, the patient now has only nine remaining teeth. The management adopted and alternative approaches are critically reviewed. The implications of the dental findings for current concepts of the pathogenesis of periodontal disease and dental caries are discussed.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
5/38. Subgingival plaque and loss of attachment in periodontosis as observed in autopsy material.Histologic sections from six autopsy cases which from a clinical point of view fitted into the criteria of periodontosis were examined with the aim at evaluating the role of subgingival plaque in the etiology of the loss of attachment in this condition. The following pertinent observations were made: 1. The subgingival plaque in most instances was not calcified to form calculus. 2. The thickness of the subgingival plaque varied between 20 and 200 mu (0.02-0.2 mm). 3. Where loss of attachment had taken place, the distance from the most apical part of the subgingival plaque to the most apical point of the epithelial cuff varied between 0.2 and 1.1 mm; this distance was never found to be more than 1.1 mm. This would indicate a cause and effect relationship, the plaque being the obvious cause. 4. There was very severe chronic inflammation in the soft tissue bordering upon the plaque with resulting collagenolysis. 5. The cellular infiltration and the collagenolysis may be limited to a zone of 1 to 2 mm in the immediate vicinity of the plaque. Between the inflamed area and the surface of the gingivae buccally and lingually there may be a fairly wide zone of healthy tissue which hides the symptoms of inflammation from being observed on a clinical examination. In turn this could leave the clinician with the impression that attachment has been lost and bone resorbed because of degenerative changes. The following conclusions can be made: In these six cases of "alveolar bone loss vastly out of proportion to what one would expect from the local etiologic factors in the patient at that age" there was no morphologic evidence that degenerative changes were responsible for the loss of attachment. On the contrary inflammatory changes induced by the subgingval plaque dominated the histopathologic picture.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
6/38. 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 = 123495.06682869keywords = periodontitis (Clic here for more details about this article) |
7/38. Features of severe periodontal disease in a teenager with chediak-higashi syndrome.BACKGROUND: chediak-higashi syndrome (C-HS) is a rare congenital disease characterized by defective neutrophil function with abnormal lysosomal inclusions, neutropenia, and reduced chemotaxis. The complete syndrome includes oculocutaneous albinism with photophobia, neurologic features, recurrent infections, and enterocolitis. methods: A 14-year-old male C-HS patient was referred to us because of serious periodontal destruction with acute inflamed gingiva and ulcers. Clinical and biological investigations were performed, leading to the diagnosis of C-HS. RESULTS: Laboratory findings included neutropenia and hypergammaglobulinemia. Peripheral blood smears showed giant granules in neutrophils, eosinophils, and granulocytes. bone marrow smears showed giant inclusions in leukocyte precursor cells. These granules and inclusions were characteristic of chediak-higashi syndrome. Oral radiographic status showed extensive loss of alveolar bone leading, in most cases, to tooth exfoliation. bacteria often associated with periodontitis were detected in subgingival plaque samples, including fusobacterium nucleatum, campylobacter rectus, prevotella melaninogenica, peptostreptococcus anaerobius, and clostridium sp. Biopsies of periodontal tissues for light and electronic microscopic examinations revealed massive bacterial invasion of the epithelial tissue, epithelial cells, and connective tissue. Ultrastructural observations of periodontal polymorphonuclear leukocytes showed defective granulation, with abnormal granules not discharging their lysosomal content against engulfed bacteria. Viable dividing bacteria were found in the cytoplasm. CONCLUSIONS: In this case, early-onset periodontitis seems to be the expression of C-HS granulocyte deficiency. Periodontal treatment of these patients is often unsuccessful. This case report illustrates the importance of the dentist in initiating clinical and biological investigations in such early aggressive periodontitis in young patients.- - - - - - - - - - ranking = 33681.472771461keywords = periodontitis, alveolar (Clic here for more details about this article) |
8/38. Combined treatment of periodontal disease and benign mucous membrane pemphigoid. Case report with 8 years maintenance.BACKGROUND: Desquamative gingivitis may be the clinical manifestation of one of several systemic diseases. The clinical course of the disease can be complicated by plaque-associated periodontitis. However, there is no information currently available for the concurrent management of both conditions. CASE REPORT AND RESULTS: This paper presents the treatment and 8-year maintenance of a patient with periodontal disease and benign mucous membrane pemphigoid (BMMP). The first phase of treatment included oral hygiene instructions and local corticosteroid administration, followed by scaling and root planing. The patient's compliance and excellent response to therapy allowed for subsequent surgical pocket elimination and augmentation of the zone of keratinized tissue for prosthetic reasons. Over the following 8 years, the patient's periodontal condition remained stable even though periodontal maintenance was erratic. For the control of BMMP, intermittent administration of corticosteroids was necessary, without any significant local or systemic side effects. CONCLUSIONS: We suggest that combined treatment and long-term maintenance of BMMP and periodontitis are feasible under certain conditions and propose a clinical protocol for treatment which could serve as a guideline for similar conditions.- - - - - - - - - - ranking = 22453.648514307keywords = periodontitis (Clic here for more details about this article) |
9/38. Combined mechanical and antibiotic periodontal therapy in a case of Papillon-Lefevre syndrome.BACKGROUND: Papillon Lefevre syndrome (PLS) is a rare entity and, as such, it is almost impossible to evaluate an effective therapy in a randomized controlled study. The amount of success reported after therapy for prepubertal periodontitis (PP) in PLS is highly variable from case to case. The goal of this case report is to evaluate the effects of a combined mechanical and antibiotic periodontal therapy regimen in the management of PLS. methods: A male patient was diagnosed as suffering from PP associated with PLS at the age of 7 years. He showed hyperkeratosis of the palms and soles, as well as advanced periodontal disease already affecting permanent teeth with maximal probing depth and vertical attachment loss of 12 mm and 11 mm, respectively. Subgingival debridement was performed with simultaneous administration of oral 250 mg amoxicillin 3 times daily and 250 mg metronidazole twice daily for one week. Clinical parameters were assessed and subgingival plaque was collected from all teeth prior to therapy and 7 and 26 months after treatment. Selective cultures for A. actinomycetemcomitans were incubated for each individual tooth and DNA probe analysis was performed for various periodontal pathogens. RESULTS: Prior to combined mechanical and antibiotic treatment, all teeth but one harbored actinobacillus actinomycetemcomitans subgingivally. However, at 7 and 26 months after therapy A. actinomycetemcomitans could be detected neither by culture nor by dna probes. Clinical parameters improved markedly and teeth erupting after therapy did not exhibit attachment loss of more than 1.5 mm during the observation period. CONCLUSIONS: Eradication (suppression beneath detection levels) of A. actinomycetemcomitans seems to play a significant role in the successful treatment of localized prepubertal periodontitis in PLS.- - - - - - - - - - ranking = 22453.648514307keywords = periodontitis (Clic here for more details about this article) |
10/38. Metal piercing through the tongue and localized loss of attachment: a case report.The piercing of intraoral structures to accommodate different types of jewelry has increased in popularity in the last few years. The association of an intraoral piercing with localized periodontitis is not well documented in the literature. A 22-year-old male presented to our clinic with a tongue stud placed through the mid-dorsum of his tongue. The inferior sphere was coated with plaque and calculus. Teeth #24 and #25 exhibited 6 mm interproximal probing depth and recession, horizontal radiographic bone loss, and tissue indentations consistent with the shape of the inferior ball of the tongue stud directly on the lingual surfaces of both teeth. The treatment consisted of an adult prophylaxis, flap curettage of the mandibular anterior region, oral hygiene instructions, and removal of the tongue stud. At our follow-up visit, the patient's oral hygiene had improved, he has removed the jewelry, and the attachment loss appears to have stabilized.- - - - - - - - - - ranking = 11226.824257154keywords = periodontitis (Clic here for more details about this article) |
