Does not respond well to improved oral self-care or professional therapy. two flavor additives known to cause allergic reactions of the gingiva? - Correct Answer- Cinnamon and carvone Acute gingivitis - Correct Answer-short duration; resolves upon professional and good self-care. Chronic gingivitis - Correct Answer-may exist for years without ever progressing to periodontitis; resolves upon professional and good self-care peri-implant gingivitis - Correct Answer-inflammatory conditions affecting the soft and hard gum tissues around dental implants Plaque-Induced Gingival diseases - Correct Answer-periodontal diseases involving inflammation of the gingiva in response to dental plaque is plaque induced gingival disease reversible? - Correct Answer-yes, with good patient self-care plaque-induced gingival disease radiographs? - Correct Answer-Reveal no changes in height or character of the bone Gingival diseases modified by systemic factors? - Correct Answer-plaque initiates the disease and then specific systemic factors found in the host modify the disease process. Example: puberty, pregnancy, diabetes, leukemia Gingival diseases modified by medications-Gingival Enlargement - Correct Answer- Onset within 3 months, higher prevalence in children, gingiva on anterior sextants most commonly affected. first observed at the interdental papilla. Non-Plaque-Induced Gingival lesions - Correct Answer-manifestation of immunosuppression. Does not respond well to improved oral self-care or professional therapy Chronic periodontitis Signs and symptoms - Correct Answer-Pain usually is NOT a symptom. Clinical appearance is NOT a reliable indicator of the presence or severity of chronic periodontitis Chronic periodontitis - Correct Answer-most common form, Irreversible loss of attachment bone. slight chronic periodontitis - Correct Answer-no more than 1 to 2mm of clinical attachment loss moderate chronic periodontitis - Correct Answer-3-4 mm of clinical attachment loss Severe chronic periodontitis - Correct Answer-5 mm or more of clinical attachment loss Recurrent Chronic Periodontitis - Correct Answer-new signs of destructive periodontitis that reappear after therapy Aggressive Periodontitis - Correct Answer-bacterial infection characterized by rapid destruction of Periodontal ligament, Supporting alveolar bone what are the three main categories for gingival diseases with modifying factors - Correct Answer-systemic, medications, malnutrition. Epithelial ridges - Correct Answer-extensions of the epithelium that reach down into the connective tissue Connective tissue papillae - Correct Answer-fingerlike extensions of the connective tissue that extend up into the epithelium Gingival Epithelium - Correct Answer-It is a type of stratified squamous epithelium that is designed to function well in wet environment of the oral cavity Why is Epithelium Important? - Correct Answer-creates a barrier to stop bacteria and viruses from entering the body Functions of Fiber Bundles - Correct Answer-Brace the free gingiva firmly against the tooth, Provide rigidity to withstand chewing.. etc. Periodontal Ligament (PDL) - Correct Answer-Thin sheet of fibrous connective tissue located between the tooth and its bony socket loctation of Acellular Cementum - Correct Answer-Covers cervical third or half of the root Cellular Cementum - Correct Answer-Continues to form after the tooth eruption, Less calcified than the acellular cementum. Osteoclasts - Correct Answer-bone consumers remove mineralized material and organic matrix Osteoblasts - Correct Answer-bone builders initiate mineralization of bone. Pathogenesis - Correct Answer-is the sequence of events that occur during the development of a disease or abnormal conditionv -itis - Correct Answer-It is a suffix meaning inflammation. For example, appendicitis is an inflammation of the appendix Gingivitis - Correct Answer-A bacterial infection that is confined to the gingiva Results in reversible destruction to the tissues of the periodontium Periodontitis - Correct Answer-A bacterial infection of all parts of the periodontium. Results in irreversible tissue damage. Horizontal Pattern of Bone Loss - Correct Answer-Is the most common pattern of bone loss Results in a fairly even, overall reduction in the height of bone Vertical Pattern of Bone Loss - Correct Answer-Leaves a trenchlike area of missing bone alongside the root Suprabony Pocket - Correct Answer-It occurs when there is horizontal bone loss. JE is located coronal to the crest of the alveolar bone (above the crest of bone). Infrabony Pocket - Correct Answer-It occurs when there is vertical bone loss. JE is located apical to the crest of the alveolar bone (below the crest of bone). Base of the pocket is located within the cratered-out area of bone alongside the root surface Attachment loss - Correct Answer-destruction of the fibers and alveolar bone Epidemiology - Correct Answer-The study of the health and disease within the total population (rather than an individual), and the study of risk factors that influence health and disease Disease Prevalence - Correct Answer-It is the number of all cases of a disease (both old and new) that are identified in a specific population at a given point in time. Incidence - Correct Answer-the number of new disease cases in a population that occur over a period of time The depth of a clinically normal gingival sulcus is - Correct Answer-1-3mm Which of the following structures is not part of the periodontium - Correct Answer- Periodontal abcess The thin bone layer that lines the tooth socket is known as the cancellous bone.
