Abstract

The present study evaluated the effect of combining an enamel matrix derivative (EMD) and a bioresorbable membrane (GTR) in the surgical treatment of degree III mandibular furcation involvements. Nine patients with chronic periodontitis, presenting a total of 14 degree III mandibular furcation involvements, were included in the study. Surgical treatment of the defects was randomly assigned: (1) EMD (four defects); (2) GTR (three defects); and (3) EMD and GTR (seven defects). The degree of involvement was assessed prior to surgery and after 6 and 12 months by measuring the probing attachment level in the horizontal and vertical directions at the furcation site. At 6 and 12 months, partial closure of the involvements had occurred in approximately half of the treated furcations, and the vertical probing level consistently improved following all three treatment modalities. The results suggest that all three treatment modalities may improve healing following surgical treatment of degree III mandibular furcation involvements. However, further studies are needed to examine the clinical significance of these results and the histologic characteristics of the healing following application of EMD. [ABSTRACT FROM AUTHOR]

Abstract

The aim of the present study was to evaluate the clinical outcome following application of an enamel matrix derivative in degree II mandibular furcation involvements. Ten patients with chronic periodontitis, presenting a total of eight buccal and eight lingual degree II furcation involvements, were included in the study. The following clinical parameters were evaluated prior to treatment and after 6, 12, and 36 months: probing attachment level in horizontal direction in the buccal and/or lingual furcation area (PAL-H) and probing attachment level in vertical direction (PAL-V) at the center of the buccal/lingual furcation area. The postoperative healing phase was uneventful in all cases, and no complications were observed throughout the entire study period. At 6 months, the mean PAL-H of the buccal defects was reduced from 4.0 +/- 1.3 mm to 2.6 +/- 1.4 mm, and the mean PAL-V was reduced from 5.2 +/- 2.0 mm to 4.0 +/- 1.6 mm. At the lingual defects, the mean PAL-H was reduced from 3.6 +/- 1.3 mm to 3.1 +/- 1.1 mm, and the mean PAL-V was reduced from 5.6 +/- 2.0 mm to 4.3 +/- 1.8 mm. At 12 and 36 months, clinical parameters remained similar, without any further clinical improvement. These results suggest that the treatment of degree II mandibular furcation involvements with enamel matrix derivative might lead to clinical improvement. However, controlled clinical trials and histologic studies are needed to examine the clinical significance of these results and the characteristics of healing following application of enamel matrix derivative.

Abstract

The fifth edition of Clinical Periodontology and Implant Dentistry brings to its readers another iteration of the unrivalled, unparalleled work on the specialty of periodontics. The editors have brought together contributions from experts all over the world to provide the reader with a comprehensive, cohesive text that fuses scholarship and science with clinical instruction and pragmatism. Clinical Periodontology runs the gamut of sub-disciplines and topics within periodontics and implant dentistry, supporting an intellectually and internationally inclusive approach. The fifth edition includes a wealth of new and revised chapters that reflect developments in the field in the years since the fourth edition was published. The sections on anatomy of the periodontium and the basic sciences underlying tooth and implant attachment have been expanded, as has the section on pathology and pathogenesis of periodontitis. Increased interest in the interdisciplinary aspects of periodontology is reflected by new chapters on orthodontic anchorage. Other important topics with increased prominence include: risk assessment and host-modulation therapies, regenerative therapies, and a full discussion of surgical and non-surgical therapies. With an approximate increase in length of 25% and over 15 new chapters, the 5th edition of Clinical Periodontology and Implant Dentistry has grown beyond the confines of one volume. Two volumes divide the topics into basic sciences and applied clinical concepts, at the same time maintaining a seamless integration between the two. This book is the cornerstone of periodontology, and represents a unique distillation of the specialty by an expert group of authors under the tutelage of a legendary editorial team.

Abstract

The aim of this study was to investigate the effect of bone grafting, suture transplantation, and guided tissue regeneration (GTR) treatment on healing of craniectomy defects involving the sagittal cranial suture and on the growth of the cranial vault. Fifty 4-week-old rats were included in the study. A 5.0 mm wide trephine defect was created with its midline corresponding to the sagittal cranial suture between the coronal and occipital cranial vault sutures. The animals were randomly allocated to five groups of 10 animals. Group A: The cranial defect was left untreated. Group B: An occipital bone graft was placed into the cranial defect. Group C: A cranial bone graft including a portion of the frontal suture was placed in the cranial defect. Group D: The cerebral and galeal aspect of the defect were covered with an e-PTFE membrane. Group E: The animals were sham-operated, no defect was created. In all animals, two gutta-percha points were placed demarcating the lateral borders of the parietal bones. Histological analysis at 4 months following surgery showed that the untreated cranial defects healed with fibrous connective tissue. The bone-grafted defects healed partially with bone and connective tissue in the periphery of the bone graft. The healing of suture-grafted defects resembled that of the bone-grafted defects, since the transplanted suture became completely obliterated with bone. The membrane-treated defects healed with bone and a suture-like tissue resembling the sagittal suture of the sham-operated controls. Cephalometric measurements demonstrated that membrane-treated and sham-operated control animals exhibited significantly more (P < 0.05) coronal growth (approximately 1.2 mm) than that of the remaining three groups of animals (approximately 0.7 mm). These findings were supported by the craniometry measurements demonstrating that sham-operated control and membrane-treated specimens presented significantly more cranial width than that of the remaining groups of animals (P < 0.05). It can be concluded that complete osseous healing, creation of a new sagittal suture, and increased cranial growth can be achieved by the treatment of craniectomy defects with the GTR technique.
