The concept of socket preservation by placing a particulate bone allograft or xenograft into a tooth socket or on the alveolar ridge after tooth removal remains a somewhat controversial topic. The concept is that it will preserve the ridge from resorption and such that subsequent implant insertion will be easier, with fewer complications. However, one particular issue is that these materials, although not directly neurotoxic, appear to be an irritant to the nerves if they come in contact with them. We present a case series demonstrating this complication...

PURPOSE: Approximately 5% of irradiated head and neck cancer patients develop osteoradionecrosis of the mandible. The current non-surgical treatment options for osteoradionecrosis have limited effects and are based on a small number of studies. Therefore, we aimed to enhance the understanding of the pathophysiology of osteoradionecrosis by investigating changes induced by external irradiation in mini-pigs. METHODS: Sixteen Göttingen mini-pigs were divided into four groups for the application in two fractions with total equivalent radiation dosages of 25, 50, 70 Gray, and one group served as control...

Horizontal ridge augmentation with allografts has attracted notable attention because of its proper success rate and the lack of disadvantages of autografts. Corticocancellous block allografts have not been adequately studied on humans. Therefore, this study evaluated clinically and histomorphometrically the increase in ridge with after horizontal ridge augmentation using corticocancellous block allografts, and the implant success after 12 to 18 months post-implantation. In 10 implant patients (3 women, 7 men, 45 years old on average), defective maxillary alveolar ridges were horizontally augmented using freeze-dried bone allograft blocks...

The association of Morse taper implant-abutment design with the use of a smaller abutment diameter (platform-switching) may improve dental implant success rate and prevent peri-implant bone loss. The aim of the present study was to histologically and histomorphometrically evaluate the behavior of peri-implant tissues around an implant with a conical connection associated with platform-switching. A platform-switched Morse-cone connection implant was inserted in the left posterior mandible in a 61-year-old patient...

OBJECTIVES: Resorption of the alveolar process occurs following tooth loss, and appears to continue for a prolonged period. Previous study (Mays, ) with a known-age collection of human remains suggested the potential of this phenomenon for age estimation in remains of adults who have lost one or more molar teeth. This article tests this ageing technique on another known age group, and attempts to evaluate the impact of some extraneous factors on the method. MATERIALS AND METHODS: The study group comprises adult skeletons (N = 110) of documented age at death from 18th to 19th century London...

Alveolar bone resorption, which can be observed on dental panoramic radiographs (DPRs), is one of the most important signs of the progression of periodontal disease. However, quantitative and consistent evaluation of alveolar bone resorption is labor intense, because of a large number of DPR examinations performed each year. In our previous study, we developed an automated scheme for detection of three lines, corresponding to an occlusion line, an alveolar line and a root apex line, to measure the alveolar bone ratio (ABR), which may be useful to dentists in early detection of periodontal disease...

A new syndrome in dentistry, the dental space deficiency syndrome is proposed in this article. Signs and symptoms of this entity may include one or more of the following clinical dental features: tooth crowding, gingival recession, tooth impactions, rapid resorption of facial alveolar bony plates following premature tooth loss, dentally oriented sleep disorders, extended orthodontic treatment time, and malocclusion relapse following orthodontic therapy. These oral conditions, individually or collectively, seem to be associated with both genetic and functional factors...

Background. Several clinical techniques and a variety of biomaterials have been introduced over the years in an effort to overcome bone remodeling and resorption after tooth extraction. However, the predictability of these procedures in sockets with severely resorbed buccal/lingual plate due to periodontal disease is still unknown. Case Description. A patient with advanced periodontitis underwent extraction of upper right lateral and central incisors. The central incisor exhibited complete buccal bone plate loss and a 9 mm vertical bone deficiency on its palatal side...

Obesity is a major risk factor for several pathologies, including jaw bone resorption. The underlying mechanisms involved in pathological conditions resulting from obesity include chronic systemic inflammation and the development of insulin resistance. Although numerous studies have indicated the importance of the role of gut microbiota in the pathogenesis of inflammation and insulin resistance in obesity, only a few studies have established a relationship between obesity, gut microbiota and status of the jaw bone...

Morphea, or localized scleroderma, is an inflammatory disease that leads to sclerosis of the skin and underlying tissues due to excessive collagen deposition. Oral involvement is unusual and it may produce white linear fibrotic areas with a scar-like appearance, atrophy of tongue papillae, gingival recession and alveolar bone resorption. We report a case of a 13-year-old girl who consulted for progressive recession on the attached gingiva of her upper left incisors. She also presented a hypopigmented line on the left side skin of her upper lip, which continued through the vermilion and the lip mucosa, including the gingiva of the affected teeth...

Dendritic cell-specific transmembrane protein (DC-STAMP) plays a key role in the induction of osteoclast (OC) cell fusion, as well as DC-mediated immune regulation. While DC-STAMP gene expression is upregulated in the gingival tissue with periodontitis, its pathophysiological roles in periodontitis remain unclear. To evaluate the effects of DC-STAMP in periodontitis, anti-DC-STAMP-monoclonal antibody (mAb) was tested in a mouse model of ligature-induced periodontitis ( n = 6-7/group) where Pasteurella pneumotropica ( Pp)-reactive immune response activated T cells to produce receptor activator of nuclear factor kappa-B ligand (RANKL), which, in turn, promotes the periodontal bone loss via upregulation of osteoclastogenesis...
