Cigarette smoking is a well-established risk factor for periodontitis and carries an increased risk for loss of periodontal attachment as well as for bone loss.

Mechanisms of Bone Resorption in Periodontitis

In periodontal disease , not only does the bone that supports the teeth, known as alveolar bone , reduce in height in relation to the teeth , but the morphology of the remaining alveolar bone is altered. Generalized bone loss occurs most frequently as horizontal bone loss. Vertical defects occur adjacent to a tooth and usually in the form of a triangular area of missing bone, known as triangulation.

By Ashish Jain, Neeta V. Gender-based heterogeneity in periodontal disease has been witnessed in the recent past with huge mounting evidence. The composite effect of sex-based genetic structure and the sex steroid hormones runs in line with the corresponding gender-related differences in risk for chronic periodontitis. Since estrogens, the predominant sex hormones in women, show immune protective and anti-inflammatory effects in hormonally active premenopausal women, they show better periodontal status compared to age-matched men. Conversely, after menopause with a weakening estrogen signal, women may show an equal or even more serious periodontal status compared to men. Periodontal status of postmenopausal women may be improved by menopausal hormone therapy.

We developed an automatic method for staging periodontitis on dental panoramic radiographs using the deep learning hybrid method. A novel hybrid framework was proposed to automatically detect and classify the periodontal bone loss of each individual tooth.

Tobacco smoking is an independent risk factor for periodontal disease which increases periodontal pocketing, attachment loss, as well as bone loss leading to varied severity and bone destruction in the form of horizontal and vertical patterns. The aim of the present study is to determine and measure the types and severity of bone destruction in chronic periodontitis CP patients with tobacco smoking habit using intraoral periapical IOPA radiographs and transgingival probing. A total of 60 male participants with CP were included in the study. Group A comprised 30 heavy cigarette smokers and Group B comprised 30 nonsmokers. Amount and pattern of bone loss were assessed using IOPA and transgingival probing. Cigarette smokers showed more bone destruction than nonsmokers in respect to maxillary molars 4. Types of bone destruction were more of vertical patterns

Microbial etiology of periodontal diseases is well established, but the present data strongly suggest an equally important role of host immune response in the pathogenesis of periodontal diseases. The initial response to bacterial infection is a local inflammatory reaction that activates the innate immune system, causing the release of an array of cytokines and other mediators and propagation of inflammation through the gingival tissues 1, 2. Due to initiation of bacterial and host immune interaction, destruction of periodontal connective tissue results which continues until the source of infection, i. The exaggerated immune response in some patients, due to genetic factors can cause rapid breakdown of the tooth-supporting structures.

Stefan A. Alveolar bone loss is a hallmark of periodontitis progression and its prevention is a key clinical challenge in periodontal disease treatment. Bone destruction is mediated by the host immune and inflammatory response to the microbial challenge. However, the mechanisms by which the local immune response against periodontopathic bacteria disturbs the homeostatic balance of bone formation and resorption in favour of bone loss remain to be established.

Наверное, эта женщина - ангел. Она прилетела за. Ангел заговорил: - Дэвид, я люблю. Внезапно он все понял. Сьюзан на экране тянулась к нему, плача и смеясь, захлестнутая волной эмоций.

Вернулся лейтенант с маленькой коробкой в руке, и Беккер начал складывать в нее вещи. Лейтенант дотронулся до ноги покойного. - Quien es. Кто он. - Понятия не имею. - Похож на китайца. Японец, подумал Беккер.

Беккер осмотрел свой бок. На рубашке расплывалось красное пятно, хотя кровотечение вроде бы прекратилось. Рана была небольшой, скорее похожей на глубокую царапину.
