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.

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 . Molecular biology of the host-microbe interactions in periodontal diseases … 2- Iatrogenic factors. 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. localized periodontal disease [2,3]. NO, they do not initiate periodontal disease. Supra- and subgingival calculus deposits act as local plaque retention factors. Local predisposing factor of periodontal disease. Xerostomia. Calculus. Figure 14.9 Minimising the periodontal consequences of providing a partial denture. 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. Clipping is a handy way to collect important slides you want to go back to later. Mouth breathing and lack of lip seal. Local risk factors can increase the risk of development and progression of periodontal disease by acting as plaque retention factors. Figure 14.3 Overhanging restoration margins. The predisposing factors for ANUG are smoking, psychological stress, malnutrition, and immunosuppression. Necrotizing periodontal diseases are non-contagious infections but may occasionally occur in epidemic-like patterns due to shared risk factors.

Figure 14.8 Partial denture with extensive gingival coverage. Some studies also mention that these hormones can encourage the growth of bacteria that causes periodontal gum disease. 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. Original articles that reported on the risk factors for periodontal disease were included. As periodontal disease is multifactorial, effective disease management requires a clear understanding of all the associated risk factors. 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.

James G. Keagle. Biofilm and periodontal microbiology 9. Data. The periodontal disease etiology is also multifactorial and bacterial plaque plays an essential role in inducing the disease [ 8, 9 ]. Calculus (supra- and subgingival) Restorations. 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. 7- Food impaction and retention. (1) Mohemid M. Al- Jebouri. Do local contributing factors cause periodontal disease? 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. (c) Following removal of the denture, the gingivae can be seen to be reddened and inlamed. 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. All of them cause an increase in estrogen and progesterone levels. Initiation and progression of periodontal infections are clearly modified by local and systemic conditions called risk factors. Calcular deposits are the most common predisposing factor. Fraenal attachments. periodontal disease that allows an individual to function normally and avoid consequences (mental or physical) due to current or past disease. It has a hard, porous, and irregular surface where plaque can accumulate easily. Billy M. Pennel.
