1/66. 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. ( info)

2/66. Treatment of Class II furcation lesions using an autogenous periosteal barrier.

    Over the last two decades, guided tissue regeneration has achieved significant advances in periodontal healing that confirm the efficacy of periodontal regeneration. Several types of barriers have been utilized to apply this principle to periodontal wound healing. The objective of this article is to review the literature and principles of guided periodontal tissue regeneration (GPTR) in the treatment of Class II furcation defects and to describe a surgical technique that utilizes the neighboring periosteum of the furcation lesion as a barrier for the clinical application of GPTR.

3/66. Effective periodontal treatment in a patient with type IIA von Willebrand's disease: report of a case.

    von Willebrand's disease (vWD) is one of the most common hereditary hemorrhagic disorders. A mild to moderate deficiency of factor viii and von willebrand factor (vWf) often is associated with gingival bleeding. In this case report, the periodontal treatment of a patient with vWD is described. A 45-year-old woman with type IIA vWD was referred for periodontal therapy because of an episode of gingival hemorrhage and percussion pain of teeth #18 and #47. The periodontal findings included probing depths ranging from 2 to 6 mm, horizontal bone loss, and Class II furcation involvement of tooth #46. After consultation with a hematologist, apically positioned flap surgery and hemisection were performed on tooth #46 following completion of oral hygiene instruction, scaling and root planing, and endodontic therapy. The patient was given 500 units of factor viii including vWf multimer 30 minutes before surgery. After healing of the periodontal tissue, prosthodontic treatment was undertaken on the posterior mandibular sextants. At follow-up, the probing depths ranged from 2 to 3 mm, and gingival bleeding on probing was minimal. The patient's children all had vWD. They had mild to moderate periodontitis with probing depths ranging from 2 to 5 mm and gingival bleeding on probing. With the combined efforts of the periodontist and hematologist, effective periodontal treatment can be provided to patients with von Willebrand's disease. ( info)

4/66. 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.

5/66. 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.

6/66. Treatment of furcation defects with DFDBA combined with GTR: human histologic evaluation of a case.

    The purpose of this study was to evaluate whether regeneration is possible in human furcation defects. Three molars with Class II furcation involvement were included in this study. A notch was placed in calculus in the furcation to serve as a reference point for histologic evaluation. The defects were treated with a demineralized freeze-dried bone allograft combined with a bioabsorbable membrane. At 6 months postoperative, the teeth were extracted with a small piece of tissue from the furcation area. The samples were then processed for histologic evaluation. Regeneration was found in 2 of the 3 samples. This study demonstrated that regeneration is possible in human furcation defects. ( info)

7/66. Furcation involvement in posterior teeth.

    This article presents two cases in which different treatments were used for mandibular molars with furcation lesions. In the first case, a conventional amputation treatment of the distal root was performed to save the mesial root as a terminal tooth, which was used as a partial denture abutment. The second case describes a relatively new technique in which a root perforation was filled with graft material (synthetic bioglass) and covered with a resorbable membrane to treat an iatrogenic furcation lesion adjacent to the mesial root. Twelve months after surgery, periapical radiographs of both treated cases showed increased bone density. Follow-up in both cases--30 months in the first case and 12 months in the second--showed no pathological recurrence or clinical dysfunction. Root amputation may provide an alternative to extraction in periodontally involved molars. Synthetic bone replacement materials combined with guided tissue regeneration may also help to correct osseous defects incurred by recent furcation perforations with associated bone loss. ( info)

8/66. The versatility of calcium sulfate: resolving periodontal challenges.

    The multifaceted properties of calcium sulfate demonstrate its usefulness in periodontal practice. calcium sulfate can function as a resorbable space filler, a resorbable barrier (compatible with guided tissue regeneration principles) and as a vehicle for controlled-release chemotherapy. Various periodontal challenges are demonstrated through case reports using calcium sulfate. ( info)

9/66. Mandibular and maxillary furcation tunnel preparations--literature review and a case report.

    AIM: The objective of this literature review and subsequent case report is to discuss and illustrate the tunnel preparation procedure as a treatment alternative for furcation-involved molars. review OF THE literature: Furcation tunnel preparation, i.e., the creation of access for plaque control between periodontally diseased roots, has not been discussed in the literature as comprehensively as root resective therapy, though success rates appear to fall within the same range. A short root trunk and a wide furcation entrance diameter are prerequisites for the indication of the tunnel preparation procedure. Although accessory canals in the furcation area are frequent findings on extracted teeth, endodontic complications have not been reported to be major complications after tunnel preparation. Caries developed at tunneled teeth even under proper maintenance, but did not necessarily lead to the loss of an affected tooth. CASE REPORT: In the case presented to illustrate the indication for the tunnel preparation procedure, periodontal disease was almost entirely restricted to the furcation sites of molar teeth. Affected teeth were either extracted or left intact and subjected to tunneling procedures. Periodontal health could be established and maintained at both single and double tunnels over a period of 2 years of periodontal supportive therapy. ( info)

10/66. Subgingival restorations with resin ionomer: a periodontal alternative.

    The successful use and placement of subgingival resin-ionomer restorations in both anterior root and molar furcation defects are demonstrated in this article. Sustained tissue health and minimal probing depths at the surgical site demonstrate clinical success. These case reports illustrate the continued success of alternative treatment procedures for restoring subgingival mechanical root or periodontal lesions. ( info)
