level questions: DISEASES OF THE PERIAPICAL TISSUE

Question	Answer
Inflammation is confined in the pulp	Pulpitis
chronic inflammatory disorder of periradicular tissues caused by etiological agents of endodontic origin.	Apical Periodontitis
serves an important protective function, aimed at confining bacteria discharged from the root canal space and preventing them from spreading into adjacent bone marrow spaces and other remote sites.	Apical Periodontitis
serves an important protective function, aimed at confining bacteria discharged from the root canal space and preventing them from spreading into adjacent bone marrow spaces and other remote sites.	Apical Periodontitis
tissue injury and inflammation developed within the periodontal ligament	Acute Apical Periodontitis
ETIOLOGY: Acute Traumatic Apical Periodontitis	Blow, kick or fall upon the face and teeth; Injuries during dental operation; Excessive occlusal stress
ETIOLOGY: Acute Chemical Apical Periodontitis	drugs introduced into pulp canal
medicament that causes necrosis of periodontal membrane with bone resorption	phenol
pathology of acute chemical apical periodontitis	phenol
medications used that may cause acute chemical apical periodontitis	sodium hypochloride, phenol, hydrogen perioxide, formocresol
acute inflammation of periapical tissues due to pathogenic microorganisms that reached the apical foramen through the pulp canal and spreads into periodontal tissues	Acute Infective Apical Periodontitis
pathology of acute infective apical periodontitis	heperemia of blood vessel, slowing of circulation of blood in the pulp, migration of WBC
Acute Dento-Alveolar Abscess: upper lip swollen stiff & distended	Mx anteriors
Acute Dento-Alveolar Abscess: upper portion of cheek swollen, lower eyelid edematous	Mx PMs & M
Acute Dento-Alveolar Abscess: lower lip & chin region swollen	Mnd Anteriors
Acute Dento-Alveolar Abscess: swollen lower part of cheek, angle of mandible, submaxillary region	Mnd Posteriors
refers to the feeling of strangling and choking, secondary to obstruction of the airway.	Ludwig's angina
Chronic Periapical Inflammation factors:	low virulence of bacteria, high body resistance, presence of drainage
possible drainage:	crown of tooth, fistula
Types of Chronic Periapical Inflammation:mass of granulation tissue at periapical area as response to mild irritation	Dental Granuloma
Types of Chronic Periapical Inflammation:simplest form of chronic periapical inflammation	Dental Granuloma
Types of Chronic Periapical Inflammation:constant seepage of toxic products into periapical tissues from infected pulp	Dental Granuloma
Types of Chronic Periapical Inflammation:inflammatory exudates near the apical foramen is confined at the center or within the fibrous wall of the granuloma	Closed granuloma
Types of Chronic Periapical Inflammation:pus develops at the center of granuloma and succeeds in perforating through bone into the oral cavity forming a sinus where discharge exudate passes	Discharging granuloma
an abnormal passage from the apical periodontal area of a tooth to the surface of the oral mucous membrane, permitting the discharge of inflammatory or suppurative material	Fistula
Types of Chronic Periapical Inflammation:Epithelium encloses the areas of necrotic granulation tissue or lining the inner surface of the abscess sac after the center has broken down	Epitheliated granuloma
Types of Chronic Periapical Inflammation:Epithelial cells derived from the epithelial rest of Malassez found in the periodontal ligament	Epitheliated granuloma
Types of Chronic Periapical Inflammation:represents a healed abscess after infection has subdued	Sclerosed Granuloma
Types of Chronic Periapical Inflammation:granulation tissue is replaced by collagen fiber bundles	Sclerosed Granuloma
Types of Chronic Periapical Inflammation:inflammatory cells disappear	Sclerosed Granuloma
Types of Chronic Periapical Inflammation:root-end cyst or periapical cyst or apical periodontal cyst	Radicular cyst
Types of Chronic Periapical Inflammation:results from bacterial infection and necrosis of dental pulp	Radicular cyst
Types of Chronic Periapical Inflammation:develop from epitheliated granuloma	Radicular cyst
Types of Chronic Periapical Inflammation:originates from acute periapical abscess or granuloma	Chronic Periapical Abscess
Types of Chronic Periapical Inflammation:complaints of transient uneasiness	Chronic Periapical Abscess
Types of Chronic Periapical Inflammation:may have slight nodule on gingiva	Chronic Periapical Abscess
Types of Chronic Periapical Inflammation: in acute exacerbation, pain and swelling and small spherical mass of gum (gumboil) with fistula is observed	Chronic Periapical Abscess
Types of Chronic Periapical Inflammation:in chronic state, sensitive to percussion, gingiva on apical region is swollen and red	Chronic Periapical Abscess
