1/7. 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 = class (Clic here for more details about this article) |
2/7. The mandibular molar class III furcation invasion: a review of treatment options and a case report of tunneling.BACKGROUND: The predictable management of a mandibular molar that has lost all of its interradicular periodontal support-in other words, that has experienced a Class III furcation invasion, or FI-often is a frustrating and disappointing process for both clinician and patient. The strategic value of retaining such a periodontally involved tooth must be determined by both the patient and dentist before a treatment option is selected. In this article, the authors present and describe various therapeutic plans available for Class III FIs in mandibular molars, discussing the advantages and disadvantages of each approach. They focus particularly on a surgical technique called "tunneling," which is performed to debride the remaining soft and hard tissues in the furcal area; this, in turn, allows access for effective oral hygiene and maintenance. CASE DESCRIPTION: The authors report on the 23-year result of a case involving tunneling. The procedure facilitated the retention of a mandibular molar with a Class III FI in a manner acceptable to both the patient and the clinician. CLINICAL IMPLICATIONS: Tunneling, in a properly selected patient who is motivated to perform careful oral hygiene, can result in comfortable, functional, healthy retention of the affected tooth, with a minimal commitment of time and financial outlay.- - - - - - - - - - ranking = 1keywords = class (Clic here for more details about this article) |
3/7. Bioactive glass and bioabsorbable membrane in the treatment of a maxillary class II furcation defect: case report with 6-month re-entry.The combination of bone graft materials with guided tissue regenerative procedures has been shown to have predictable positive results in periodontal defects, especially furcations. The following case report will demonstrate a severe class II furcation defect in a maxillary molar that was treated with combination therapy using bioactive glass and a bioabsorbable membrane made of a copolymer of polylactic/polyglycolic acid. Six-month re-entry revealed substantial clinical fill of the furcation defect. Comparison radiographs also demonstrated fill in the region.- - - - - - - - - - ranking = 1.25keywords = class (Clic here for more details about this article) |
4/7. Treatment of mandibular class II furcation defects by the use of amelogenins and autologous bone. Two case reports.The aim of this preliminary study was to evaluate the clinical effectiveness of the association of amelogenins and autologous bone graft in the management of mandibular class II furcation defects. This randomized case-controlled study was conducted on 2 patients who presented 2 contralateral mandibular buccal class II furcation lesions. One defect was treated by amelogenins and autologous bone graft (test site) and the other one by open flap debridement (control site). At baseline and at 12 months postoperatively, the full-mouth plaque score (FMPS) and the full-mouth bleeding score (FMBS), the probing depth (PD), the clinical attachment level (CAL) and the recession (REC) were recorded and a periapical radiograph of the selected area was taken. In addition, at 12 months a surgical re-entry was performed. Test sites had a greater horizontal PD reduction and radiographic bone filling compared to control sites. None of the treated sites achieved complete furcation closure. At the time of re-entry, furcations treated by amelogenins were partially filled by newly formed not soundable hard tissue, while furcations treated by conventional flap surgery were filled by epithelial and connective tissue. These findings suggest that the treatment of mandibular class II furcations by amelogenins and autologous bone graft may result in a significant clinical improvement. Further long-term studies conducted on a larger sample size are therefore needed to confirm our results.- - - - - - - - - - ranking = 1.75keywords = class (Clic here for more details about this article) |
5/7. A combined surgical and orthodontic treatment of Class III furcations. Report of a case.oral hygiene in furcation defects of upper molars is difficult to achieve. In this case report, a combined surgical and orthodontic treatment procedure is presented to facilitate access and plaque control in furcation areas of upper molars with class-III furcation defects. After endodontic treatment and root resection in an upper 1st molar, the remaining mesiobuccal and palatal roots were separated and aligned orthodontically within the dental arch, as one-rooted teeth. The new morphological position of the roots greatly facilitated oral hygiene and may offer a better long-term prognosis.- - - - - - - - - - ranking = 0.25keywords = class (Clic here for more details about this article) |
6/7. The treatment of class III maxillary furcations using a resin-ionomer. A case report.This case report uses a resin-ionomer restoration as a barrier in the treatment of a Class III furcation defect. There was a reduction in tooth mobility and plaque count, no bleeding on probing, and a decrease in probing depth with the use of the resin ionomer. The study offers another treatment option in the treatment of a seemingly hopeless maxillary molar.- - - - - - - - - - ranking = 1keywords = class (Clic here for more details about this article) |
7/7. The buccal bifurcation cyst: in non-surgical treatment an option?The mandibular buccal bifurcation cyst (BBC) was first described by Stoneman and Worth in 1983. It is a lesion with a specific location, classically the buccal surface of the mandibular first molar and less frequently the mandibular second molar. There have been numerous reports in the literature describing the BBC and its treatment. Treatment advocated thus far includes extraction of the involved first molar, marsupialization and enucleation of the cyst. In their most recent article, Pompura, Sandor and Stoneman reported on the successful treatment of 44 cysts with enucleation without tooth extraction. This article will describe the diagnostic features of the BBC and present three cases with a total of five cysts, which were treated non-surgically and ultimately resolved. The authors, therefore, propose that a more conservative non-surgical approach to these lesions may be considered.- - - - - - - - - - ranking = 0.25keywords = class (Clic here for more details about this article) |
