The periodontium is an integrated, functional unit of multiple tissues surrounding and supporting the tooth, including but not limited to cementum (CM), periodontal ligament (PDL) and alveolar bone (AB). Restoration of the teeth and the periodontium share an inseparable relationship. Bacterial & inflammatory products.via accessory canals, apical foramina or dentinal tubules. Thus, a definition for periodontal health was included in this classification, which serves as a treatment endpoint goal Any occlusal force which goes beyond the adaptive capacity of our periodontium causes injury to periodontal structures, and the resultant. Periodontitis is an inflammatory disease with microbial etiology being its primary etiology. It usually occurs as a complication of advanced gum disease (periodontitis), which is caused by poor oral hygiene. 3. The center of rotation is midroot. The periodontal ligament space varies along the length of the roots. 2. Periapical periodontitis or apical periodontitis (AP) is an acute or chronic inflammatory lesion around the apex of a tooth root, most commonly caused by bacterial invasion of the pulp of the tooth. Core tip: During the incipient steps of periodontal treatment, clinicians are usually asked to predict the prognosis of teeth with compromised periodontium. Authors M Arioka 1 . In 1890, he published a book titled Microorganisms of the Human Mouth. The damage caused to the periodontium by subgingival margins is an under-recognized aspect of restorative dentistry. Based on the results of recent research in the field, the present paper will discuss the protective and destructive aspects of the innate vs. adaptive (humoral and cell-mediated) immunity associated with the bacterial virulent factors or antigenic determinants during periodontal pathogenesis.

By Dr. George Ghidrai The periodontium (also known as marginal periodontium) is the supporting structure of a tooth, helping to attach the tooth to surrounding tissues and to allow sensations of touch and pressure. Anatomy of the Periodontium In order to understand how disease processes can affect the oral cavity, it is important to know the structure of the periodontium. Periodontal tissues can be destructed by chronic periodontal disease, which can lead to tooth lo … It tends to be wider at the apex and alveolar crest, and narrower in the midroot areas. Destruction of the periodontium is normally associated with periodontal disease, although many other factors, such as trauma, aging, infections, orthodontic tooth movement and systemic and genetic diseases, can contribute to this process. Healthy strong gingiva is pink in color, has . Pdl fistulation Extraosseous fistulation Effect Of Periodontal Disease On Pulp A clear cut relationship ..less evident. The periodontal ligament allows movement around a center of rotation. Since the 1970s, a number of procedures have been investigated in an attempt to restore such lost tissues. What is periodontitis? Horizontal bone loss is the most common pattern ol bone loss in periodontal disease. Single tooth anterior dental crossbite is the commonly encountered malocclusion during the development of occlusion in children. trauma is called as trauma from occlusion (TFO), several . These are found in the oral cavity or mouth of a human being surrounding part of the teeth.. Orthodontic tooth movement is achieved by the remodeling of alveolar bone in response to mechanical loading [131, 132].When orthodontic forces are placed on the tooth, load transfer occurs from the tooth through the periodontal ligament to the alveolar bone, and causes minor reversible injury to the periodontium that supports the tooth. The interdental septa and facial and lingual plates are affected, but not necessarily to an equal degree around the same tooth (I ig. All are true about calciotraumatic line, except_____? reduction in pocket depth is more effective in non- smokers than in smokers after non-surgical periodontal therapy, including oral hygiene instructions, scaling and . LGE typically presents at the anterior teeth initially [Cherry-Peppers, et al. The fabrication and presence of dental prostheses and tooth-related factors have an impact on periodontal health and disease state. This paper presents two cases of anterior crossbite corrected using the standard Catlan's appliance (Lower Inclined Bite Plane) in a . A NEW CLASSIFICATION OF PERIODONTITIS. I he bone is reduced in height, but the bone margin remains roughly perpendicular to the tooth surface. The cells that form cementum are called cementoblasts. The group considered the term reduced periodontium related to secondary occlusal trauma and agreed there were problems with defining "reduced periodontium". Aging and the periodontium Section 2 - Classification and Epidemiology of Periodontal Diseases 3. periobasics Basic Periodontology, Recent Posts Introduction. Physiologic Form of Tooth and Periodontium. The beautiful smile comes from a harmonious coexistence of teeth and gingiva. periodontal ligament the pdl is that soft specialized connective tissue situated between the cementum covering the root of the tooth and the bone forming the socket wall the pdl ranges in width from 0.15 to 0.38mm with its thinnest portion in the middle of the root,the average width is 0.21mm at 11 to 16 years, 0.18mm at 32 to 52 years 0.15mm at … It consists of cells, which are embedded in the extracellular matrix. Due to death of odontoblastic layer C. It remains after caries is removed D. Because of odontoblastic migration from cell rich zone. 1. 0. Diagnostic Case Examples Fig. More than 800 different bacterial species are found in oral cavity.,, W. D. Miller was one of the important individuals who worked greatly on oral microbiology. Various defense mechanisms active in the oral cavity include saliva, gingival sulcular/crevicular fluid, intact epithelial barrier (junctional epithelium), the presence of beneficial flora, migrating polymorphonuclear cells and other leukocytes, and local antibody production. Dr. Enas Elgendy Ass. Combination abscesses (periodontal and periapical) occur because the periodontium is a continuous unit. The gingiva usually exhibits one of the first signs of inflammation through redness, bleeding or swelling. You now have unlimited* access to books, audiobooks, magazines, and more from Scribd.

The biologic width is essential for preservation of periodontal health and removal of irritation that might damage the periodontium (prosthetic restorations, for example). Periodontium is a complex structure, consisting of epithelial tissue (gum) and connective (periodontal ligament) and mineralized tissue (cementum and alveolar bone) (Figure 15.6). They consist of mucosal tissue that covers the alveolar processes of the maxilla and mandible and finish at the neck of each tooth.. Within this subcategory of factors influencing the periodontium, the most notable change is the replacement of the dated term, biological width, with supracrestal tissue attachment. Any occlusal force which goes beyond the adaptive capacity of our periodontium causes injury to periodontal structures, and the resultant trauma is called as trauma from occlusion (TFO), several schools of thoughts are there that whether TFO is an etiological factor or cofactor for the occurrence of periodontal diseases. 0 who need MK Jeffcoat, M McGuire and MG Newman "Evidence-based periodontal treatment. The periodontium consists of: Gingiva: it is a part of the oral mucosa that surrounds teeth and covers the maxilla and mandible. This includes the gingival tissue and its supporting bone. / IJRID Volume 1 Issue 2 Nov.-Dec 2011 Available online at www.ordoneardentistrylibrary.org ISSN 2249-488X Review- Article INTERNATIONAL JOURNAL OF RESEARCH IN DENTISTRY INFLUENCE OF HORMONES IN PERIODONTIUM - A REVIEW Dr. Vishal Anand1*, Dr. Minkle Gulati2*,, Dr. Bhargavi Anand3*,, Dr. Aparna Singh, Dr. Anika Daing, 1. Unknowingly, subgingival margins are being placed unnecessarily every day. Based on the current classification, it can be concluded that it is of extreme importance that the dentist should know how to differentiate between the origins of the periodontal-endodontic lesions, including all the routes of communication between the pulp and the periodontium which act as possible "bridges" for the microorganisms, thereby enabling the dissemination of the . The millimeter that is needed from the bottom of the junctional epithelium to the tip of the alveolar bone is held responsible for the lack of inflammation and bone . Attent … To achieve success in periodontal therapy, the sealing of the junctional epithelium, the insertion of new connective tissue fibers, the formation of new cementum, and . A reduced periodontium is only meaningful when mobility is progressive indicating the forces acting on the tooth exceed the adaptive capacity of the person or site. The periodontium anchors teeth to surrounding tissues and supports teeth during its function.

The native periodontium includes cementum, a functionally oriented periodontal ligament, alveolar bone and gingiva. A. Horizontal bone loss is the most common pattern ol bone loss in periodontal disease. Cementum, PDL and alveolar bone develop from the 1. The dental pulp originates from dental papilla and the periodontal ligament originates from dental sac, both of which have a common mesodermal origin. Cementum is a mineralized connective tissue similar to bone except that it is avascular; the mineral is also apatite, and the organic matrix is largely collagen. Over the years, periodontal diseases and conditions have been classified in a variety of ways. Not only does this book show how to do periodontal procedures, it describes how to best manage the outcomes and explains the evidence supporting each . 4 Occlusal trauma may occur in an intact periodontium or in a reduced periodontium caused by periodontal disease. Professor of Oral Medicine, Periodontology& Oral Diagnosis Faculty of Dentistry Kafrelsheikh University. The connective tissue (CT) is responsible for stability and function of the whole periodontium. Department of Pathology, University of Adelaide, Adelaide, South Australia. Orthodontic tooth movement is a process that combines physiologic alveolar bone adaptation to mechanical strains with minor reversible injury to the periodontium .Under normal/healthy conditions, such movement is carried out by highly coordinated and efficient bone remodeling, which requires coupling of bone formation following bone resorption. Infection originating in the periodontal tissues can progress to the pulp via openings at the apex or through the lateral canals, just as infection of the root canal system affecting the tooth apex can spread to the marginal tissues. Occlusal trauma is a term used to describe injury resulting in tissue changes within the attachment apparatus, including periodontal ligament, supporting alveolar bone and cementum, as a result of occlusal force(s). Various treatment options such as removable and fixed appliances have been suggested by different authors in the past literature. Collagen types I, III, IV, V and VI are distributed in a differ … PowerShow.com is a leading presentation/slideshow sharing website.

Exclusive 60 day trial to the world's largest digital library. 7, 8 Based on these variables the workshop categorized periodontitis as prepubertal, juvenile (localized and generalized), adult, and rapidly progressive. The interdental septa and facial and lingual plates are affected, but not necessarily to an equal degree around the same tooth (I ig. The gingiva contain a stratified squamous epithelium ← which develops from the of the pharyngeal arches ←. Speciic to the periodontium ample loss of elasticity and increased resistance of the tissue may are indings of a more irregular periodontal surface of bone and lead to decreased permeability, decreased nutrient low, and the less regular insertion of collagen ibers. Periodontium Periodontium refers to the specialized tissues that both surround and support the teeth, maintaining them in the maxillary and mandibular bones. To cushion the impact of the offending forces, the PDL is widened and the adjacent bone is resorbed. The simultaneous existence of pulpal problems and inflammatory periodontal disease can complicate diagnosis and treatment planning. Jessica Raymond-Allbritten, BASDH, CRDH, breaks down the new 2017 periodontal classification system and defines each category. Numerous clinical trials . Attachment loss severity was increased by 0.5% by smoking 1 cigarette per day, while smoking up to 10 and 20 cigarettes a day increased attachment loss by 5% and 10%, respectively. While it is true that within the alveolar bone the maxillary and . These fibers, unlike the fibers of the periodontal ligament, in general, attach the tooth to the gingival tissue, rather than the tooth to the . A perio-endo lesion can have a varied pathogenesis which ranges from quite simple to relatively complex one. She explains how the new system allows clinicians to better categorize patients' oral health based on clinical and radiographic findings. The periodontal abscess causes pain that becomes worse with biting on the affected tooth. It is a likely outcome of untreated dental caries (tooth decay), and in such cases it can be considered a sequela in the natural history of tooth decay, irreversible pulpitis and pulpal necrosis. The gingiva is the anatomical term for gums. Periodontium As long as the pulp maintains vital .. unlikely Impact of pulpal necrosis result in bone resorption . In the late bell stage of tooth formation, the dental sac and dental papilla are separated from each other by epithelial . This led to a lack of clarity regarding classification of diagnosis given the presence of gingival inflammation at one or more sites and a patient-level definition of gingivitis. Classification of diseases and conditions affecting the periodontium 4. A periodontal abscess is a collection of pus that occurs in the tooth-supporting tissues (the periodontium) as a result of bacterial infection. In addition, the classification system serves as a means . They are primarily composed of type I collagen, although type III fibers are also involved.. Pathologic and/or traumatic events may lead to the loss or damage of this anatomical structure.
