(c) Following removal of the denture, the gingivae can be seen to be reddened and inlamed. Local trauma. Local factors should be identified when carrying out a thorough dental examination of the patient and their removal or modification where possible should be included in the patient’s management.

Removal of calculus deposits will be of great help in the prevention and treatment of periodontal gum disease. 5- Orthodontic therapy. Figure 14.10 Orthodontic appliance acting as a plaque retention factor. General predisposing risk factor when associated with bacteria may induce generalized periodontal disease in periodontal tissues around all teeth since the response of the inflammatory process occurs and is similar in all the teeth that present opportunist bacteria.

This paper aims to review the evidence on the potential roles of modifiable and nonmodifiable risk factors associated with periodontal disease. Keywords: periodontal disease, predisposing factors, modifying factors. Local predisposing risk factor may be associated in bacterial retention increasing its quality and quantity and/or in the promotion of a mechanical vulnerability in the periodontal tissues favoring the action of bacteria, the predisposing risk factor may statistically intensify the incidence of a disease, but it does not promote the disease. periodontal disease that allows an individual to function normally and avoid consequences (mental or physical) due to current or past disease. Looks like you’ve clipped this slide to already. Figure 14.1 Section VIII.A from the classification of periodontal diseases and conditions. The periodontal disease etiology is also multifactorial and bacterial plaque plays an essential role in inducing the disease [ 8, 9 ]. Fixed Prosthodontics Department, Faculty Of Dentistry, Minia University. Endocrine conditions that could affect periodontal health are observed mostly in women. Local predisposing factors in periodontal disease  Are oral conditions or habits that increase an individual`s susceptibility to periodontal disease  These factors don't initiate gingivitis or periodontitis but contribute to the disease process initiated by dental plaque  Increase plaque retention  Interfere with plaque removal  Induce direct damage to periodontal tissues Thus In this way, as Although calculus deposits are … Mohammad Mamdouh Calculus (supra- and subgingival) Restorations. The milder form, necrotizing ulcerative gingivitis (also termed "trench mouth"), [7] is characterized by painful, bleeding gums and ulceration and necrosis of the interdental papilla . Local risk factors can increase the risk of development and progression of periodontal disease by acting as plaque retention factors. Original articles that reported on the risk factors for periodontal disease were included. Figure 14.9 Minimising the periodontal consequences of providing a partial denture. 1. Figure 14.6 Minimising the periodontal consequences of restorative treatment. Periodontal disease is the most common chronic inflammatory disease, and severe periodontitis a ects approximately 10% of the global population, with variations by country and world region [1]. periodontal disease. Calculus. Objectives. They pertain to physical structures or mechanical habitat that promote plaque accumulation and make plaque removal more difficult. The local factors include pre-existing disease as evidenced by deep probing depths and plaque retention areas associated with defective restorations. Iatrogenic factors in periodontal disease, Ch10 The Role Of Dental Calculus And Other Predisposing Factors. It has a hard, porous, and irregular surface where plaque can accumulate easily. Data. Local contributing factors & Systemic factors associated with periodontal diseases CASE 1 2. All of them cause an increase in estrogen and progesterone levels. The local predisposing risk factor may provoke a mechanical vulnerability in the periodontal tissues around a tooth, and/or may assist in bacterial retention, development and organization, in order to originate periodontal tissue destruction. The contributing factors for periodontal disease are either local or systemic. The predisposing factors for ANUG are smoking, psychological stress, malnutrition, and immunosuppression. Sources. In periodontal disease, the predisposing factors may be defined as local factor which may facilitate accumulation of bacterial plaque and/or some damage that affect periodontal tissues leading to local low resistance and fragility.

MEDLINE (1980 to Jan 2014), PubMed (using medical subject headings), and Google Scholar were searched using the following terms in different combinations: “periodontal disease,” “periodontitis,” “risk factors,” and “causal.” This was supplemented by hand-searc… of periodontal health and disease as controllable and uncon-trollable predisposing and modifying factors cannot be under-estimated, and their assessment for each patient is crucial to attaining and maintaining clinical periodontal health. In this context, predisposing factors … Figure 14.3 Overhanging restoration margins. The host response varies from individual to individual depending on many factors including the type of the bacterial insult, the duration of the insult, the local and environmental contributing factors, immunological and inflammatory responses, predisposing genetic factors, and association with systemic diseases. Biofilm and periodontal microbiology 9. Then periodontal disease is a chronic disease presenting multifactorial etiology where bacteria plays a fundamental role but always requires at least a predisposing risk factor of local and or general order which when associated may induce destructive periodontal disease. 8- Habits. Extrinsic contributing factors impact periodontal disease because they • Usually harm the tissue directly or • Allow for an increased accumulation of plaque. Necrotizing periodontal diseases are non-contagious infections but may occasionally occur in epidemic-like patterns due to shared risk factors. 3- Malocclusion.

Predisposing Factors in the Etiology of Chronic Inflammatory Periodontal Disease. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. Local risk factors could influence directly the periodontium, the most often involved local risk factors being dental calculus, malocclusions, improper or aged and degraded dental or prosthetic treatments, orthodontic appliances, affecting also the masticatory, esthetical and phonetical function consequently decreasing the quality of life. localized periodontal disease [2,3]. Many modifiable risk factors, such as smoking, contribute to increases in systemic markers of inflammation, which can further modify gene regulation through a variety of biologic mechanisms. Figure 14.5 An overcontoured crown and subgingival calclus. Initiation and progression of periodontal infections are clearly modified by local and systemic conditions called risk factors. Local factors should be identified when carrying out a thorough dental examination of the patient and their removal or modification where possible should be included in the patient’s management. Some studies also mention that these hormones can encourage the growth of bacteria that causes periodontal gum disease. Local predisposing factors affect periodontal disease 2- Iatrogenic factors.

The role of dental calculus and other local predisposing factors 8. Figure 14.8 Partial denture with extensive gingival coverage. (b) Partial denture in situ; interproximal plaque is visible. In the case of plaque-associated peri-implantitis, local contributors, including surgical and prosthetic factors, as well as soft and hard tissue characteristics, may be predisposing factors to biofilm adherence around dental implants, thus leading to inflammation. Calcular deposits are the most common predisposing factor. periodontal disease, the predisposing risk factors may be defined as local environmental factors, behavioral factors in nature and systemic factors, which may be responsible in providing an ideal environment for bacterial colonization and/or fragility in a determinate tooth or teeth and adjacent periodontal tissues and/ or interference in the inflammatory process. Other factors increasing the risk of developing periodontal disease: Bridges that no longer fit properly trap food debris and allow dental plaque to accumulate and grow between the crown and gums Malocclusion - Crooked teeth make difficult the removal of dental plaque These are puberty, menstruation, pregnancy, and menopause. Supra- and subgingival calculus deposits act as local plaque retention factors. Inflammation is a prominent feature of common chronic dis- eases, including atherosclerosis, cancer, and periodontitis.
