1/35. guided tissue regeneration in the management of severe periodontal-endodontic lesions.diagnosis of combined periodontal-endodontic lesions can prove difficult and frustrating. They are often characterised by extensive loss of periodontal attachment and alveolar bone, and their successful management depends on careful clinical evaluation, accurate diagnosis, and a structured approach to treatment planning for both the periodontic and endodontic components. Recent advances in regenerative periodontics have led to improved management of periodontal-endodontic lesions. This paper reviews the management of such lesions in light of these recent advances and illustrates this through reports of two patients who had severe periodontal involvement.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
2/35. Treatment of molar furcation involvement using root separation and a crown and sleeve-coping telescopic denture. A longitudinal study.Because of the inconsistent results of periodontal and prosthetic therapy, periodontists may choose to treat maxillary molar furcation involvements (FI) with poor root morphology utilizing a root resection technique (RRT). In addition, poor root morphology of the remaining root following RRT is usually considered a high risk factor for long-term periodontal and prosthetic success. The purpose of this retrospective study was to investigate the differences in the clinical periodontal parameters between molar abutments with and without molar root separation and/or resection (RSR) before and after periodontal and prosthetic therapy, using a crown and sleeve-coping telescopic denture (CSCTD). A total of 85 molars (47 maxillary and 38 mandibular) were treated in 25 subjects. There were 33 abutments without root separation/resection and 52 abutments with RSR. Forty-three CSCTD were placed, 23 in the maxillary arch and 20 in the mandibular arch. The mean observation period was 6.7 /-1.9 years (range, 5 to 13 years). The plaque index, gingival index, probing depth, clinical attachment level, and alveolar bone change were recorded. The differences in these parameters before and after periodontal and prosthetic therapy between the advanced furcation-involved molars with and without RSR were evaluated. The results revealed a remarkable improvement in the periodontal parameters in advanced Class II and Class III FI in molars with RSR as compared to those without RSR. It was, therefore, concluded that molar abutments with RSR in conjunction with a specifically designed telescopic device provide a modified approach for treating molars with advanced Class II and III FI.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
3/35. Implant site development using orthodontic extrusion: a case report.One of the most important factors in the successful placement of endosseous implants is the presence of adequate alveolar bone at the recipient site. alveolar bone loss associated with destructive periodontal disease frequently results in osseous defects that may complicate subsequent implant placement. Typically, such defects are treated prior to or at the time of implant surgery using the principles of guided bone regeneration. Under certain circumstances, however, such defects may be managed non-surgically by orthodontic extrusion. orthodontic extrusion can be used to increase the vertical bone height and volume and to establish a more favourable soft-tissue profile prior to implant placement. The addition, the increase in the vertical osseous dimension at interproximal sites may assist in the preservation of the interdental papillae and can further enhance gingival aesthetics. This report illustrates the treatment sequence for site development with orthodontic extrusion prior to immediate implant placement.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
4/35. A multidisciplinary approach to the diagnosis and treatment of early-onset periodontitis: a case report.BACKGROUND: The diagnosis and treatment of early-onset forms of periodontitis (EOP) represent a major challenge to periodontists. In this case report, we describe a multidisciplinary approach for the treatment of a patient with severe generalized juvenile periodontitis (GJP). Our approach incorporates clinical laboratory evaluation with conventional concepts of periodontal pathogenesis and therapeutics to diagnose and effectively treat EOP. methods: The 17-year-old female patient presented with clinical and radiographic evidence of severe attachment loss. Microbiological testing showed the presence of known periodontal pathogens including actinobacillus actinomycetemcomitans, prevotella intermedia, and porphyromonas gingivalis. Routine immunological tests did not reveal any of the functional defects thought to play a role in the pathogenesis of EOP After initiation of therapy, which consisted of scaling and root planing, supplemented with administration of systemic antibiotics, a reduction in probing depth and gain in clinical attachment could be demonstrated. Microbiological testing was used to monitor the composition of the periodontal microbiota and to adjust antimicrobial therapy accordingly. RESULTS: Using a non-surgical approach to treatment, except for 2 root amputations performed without flap reflection, we have been able to stabilize this patient's periodontal condition over the course of a 2-year follow-up period. CONCLUSIONS: This treatment strategy provides an efficacious alternative to more aggressive forms of therapy and should therefore be considered for the treatment of patients with severe EOP.- - - - - - - - - - ranking = 25002.269131355keywords = periodontitis (Clic here for more details about this article) |

6/35. Periodontal regeneration of a class II furcation defect utilizing a bioabsorbable barrier in a human. A case study with histology.This case report describes human histologic data of periodontal regeneration following guided tissue regeneration therapy (GTR) with a bioabsorbable barrier composed of polylactic acid. The tooth that was examined was part of a previously published study of the clinical effects of GTR therapy without the use of bone or bone substitutes on Class II furcation defects. Twenty-five months following the surgical procedure, the tooth was extracted for non-periodontal reasons. During this extraction, the bone within the furcation that was treated in the study was luxated with the tooth. At the completion of the study (month 12), the furcation's vertical probing depth had decreased by 2 mm with a 2 mm gain in clinical attachment. The horizontal furcation measurement decreased by 3 mm. Following extraction, the tooth was prepared for light microscopy and sectioned in the mesial-distal plane. Reference notches were not placed in the tooth at the time of surgery as there were no plans to perform histologic analysis in the study. However, using the buccal root prominences and what we interpreted to be root planing marks on the cementum, we were able to demonstrate that complete periodontal regeneration occurred on the root surface that was exposed to the pocket environment prior to surgery. New alveolar bone, cementum, and periodontal ligament were consistently observed throughout the furcation in the areas that demonstrated clinical attachment gain and a decrease in horizontal probing depth. This case report adds to the accumulating evidence of histologic periodontal regeneration following guided tissue regeneration with bioabsorbable polylactic acid barriers.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
7/35. 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 = 8334.0897104515keywords = periodontitis (Clic here for more details about this article) |
8/35. 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 = 4167.0448552258keywords = periodontitis (Clic here for more details about this article) |

10/35. aggressive periodontitis associated with Fanconi's anemia. A case report.BACKGROUND: Fanconi's anemia is an autosomal recessive disease associated with chromosomal breakage as well as pancytopenia, skin pigmentation, renal hypoplasia, cardiac defects, microcephaly, congenital malformations of the skeleton, hypogonadism, and increased risk of leukemia. The present report describes the periodontal clinical and microbiological status of an 11-year old male having Fanconi's anemia. methods: polymerase chain reaction analysis to detect human cytomegalovirus (HCMV), Epstein-Barr type 1 virus, and herpes simplex virus (HSV) was performed on paper-point samples pooled from either 3 periodontal sites with advanced attachment loss or 3 gingivitis sites with no clinical attachment loss. Anaerobic bacterial culture examination was performed on the pooled periodontitis sample. RESULTS: The patient suffered from pancytopenia, allergy, asthma, hearing impairment, and mental retardation. dentition consisted of 7 primary teeth, 11 erupted permanent teeth, and 14 unerupted permanent teeth. Most erupted teeth showed severe gingival inflammation with some gingival overgrowth and various degrees of periodontal attachment loss. Genomes of HCMV and HSV were detected in the pooled periodontitis sample and HCMV in the pooled gingivitis sample. The periodontitis sample but not the gingivitis sample revealed HCMV mRNA of major capsid protein, suggestive of active viral infection. The periodontitis sample also yielded actinobacillus actinomycetemcomitans (1.1% of total isolates), fusobacterium species (7.9%), campylobacter species (2.2%), peptostreptococcus micros (3.4%), and candida albicans (0.3%). CONCLUSIONS: Oral features of Fanconi's anemia may include increased susceptibility to periodontitis. It is likely that underlying host defense impairment coupled with periodontal infection by HCMV and A. actinomycetemcomitans contribute to the severe type of periodontitis associated with Fanconi's anemia.- - - - - - - - - - ranking = 41670.448552258keywords = periodontitis (Clic here for more details about this article) |
