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.

Mechanisms of Bone Resorption in Periodontitis

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.

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.

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.

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. Aims: The purpose of the study was to investigate the pattern of the intraoral distribution of periodontal destruction among cigarette smokers with periodontitis by assessing the periodontal probing depth PPD and clinical attachment level CAL. Materials and Methods: Thirty smokers with chronic periodontitis were enrolled in the study.

Не обращая внимания на устремленные на него любопытные взгляды десятков пар глаз, Беккер шагнул в толпу. Он ослабил узел галстука и рухнул на стул у ближайшего свободного столика. Казалось, что с той минуты, когда рано утром ему позвонил Стратмор, прошла целая вечность.

Deep Learning Hybrid Method to Automatically Diagnose Periodontal Bone Loss and Stage Periodontitis

Именно он и подал ручную команду на отзыв Следопыта. Вопрос насколько. уступил место другому - с какой целью?. У Хейла не было мотивов для вторжения в ее компьютер. Он ведь даже не знал, что она задействовала Следопыта.

Ее черный лоснящийся верх поднимался на двадцать три фута, а сама она уходила далеко вниз, под пол. Своей гладкой окружной формой она напоминала дельфина-косатку, застывшего от холода в схваченном морозом море. Это был ТРАНСТЕКСТ, компьютер, равного которому не было в мире, - шифровальная машина, засекреченная агентством. Подобно айсбергу машина скрывала девяносто процентов своей массы и мощи под поверхностью. Ее секрет был спрятан в керамических шахтах, уходивших на шесть этажей вниз; ее похожий на ракету корпус окружал лабиринт подвесных лесов и кабелей, из-под которых слышалось шипение фреоновой системы охлаждения.

Юлий Цезарь всегда с нами. Мидж развела руками. - О чем. - Квадрат Цезаря, - просияла Сьюзан.  - Читается сверху .

Ее зовут Росио. Консьерж шумно выдохнул, словно сбросив с плеч тяжесть. - А-а, Росио - прелестное создание.

Я погиб.

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.
