Periapical/apical infection

• Type of apical inflammation

  Acute apical periodontitis

  Chronic apical periodontitis
• Pus in apical periodontal membrane, pulsating pain, neutrophils are present

  Acute periapical abscess
• Type of acute apical periodontitis

  -Acute traumatic apical periodontitis (non and vital)-Acute chemical apical periodontitis (nonvital)

  -Acute infective apical periodontitis (nonvital)

  -Acute apical abscess ( Nonvital) but thickening of lamina dura

  ALL ARE CLINICALLY SYMPTOMATIC AND SLIGHT THICKENING OF PD
• Type of chronic apical periodontitis - CAP

  Dental granuloma

  Radicular cyst

  Chronic apical abscess
• All types of chronic apical periodontitis are asymptomatic and non vital? True or false?

  TRUE- thickening of pdl space
• Chronic conditions are reactions to a long-standing irritation (dental caries, necrosis, pulpitis) with more or less successful attempts to repair

  Chronic apical periodontitis
• Localized mass of chronic granulation tissue formed in response to a mild irritation or infection

  Dental granuloma/periapical granuloma
• Sequela (result or part two) of periapical granuloma

  Radicular cyst/ periapical cyst
• Sequela (result or part two) of periapical granuloma

  Radicular cyst/ periapical cyst
• Not all adicular cyst came from dental granuloma but not all

  granuloma will become a cyst, TRUE OR FALSE

  FALSE- all radicular cyst cane from dental granuloma
• Type of chronic apical periodontitis that considered as TRUE CYST

  Radicular cyst/ periapical cyst
• Explain about true cyst

  Pag lined by PS CILIATED COLUMNAR EPITHELIUM, pag walang cavity lined hindi sya cyst
• Explain about true cyst

  Pag lined by PS CILIATED COLUMNAR EPITHELIUM, pag walang cavity lined hindi sya cyst
• Foam cells sa radicular cyst

  Macrophages
• Biopsy type for radicular

  Excisional biopsy
• Surgical procedure that completely removing the lesion

  Enucleation
• Cutting the apex

  Apicoectomy
• Creating a surgical window

  Marsupialization
• What procedure you can do after marsupialization?

  Enucleation
• Strew colored

  Cystic lesion
• If a balance is established between the irritant and host

  defense, the abscess become..

  Chronic and localized
• If increase hydrostatic pressure within an abscess occur

  with progressive suppuration, pus spreads along the..

  LEAST RESISTANCE
• Severe case of complication of suppuration

  Infection in the blood stream
• Severe case of complication of suppuration

  Infection in the blood stream
• Type of acute apical abscess that known as parulis

  (pustule-primary ). Pus can be seen in gingival tissue

  Gumboil
• abscess burrowing towards the surface in attempt to drain itself

  Fistula
• Follow the least resistance through bone and tissue and can drain intraolly and extraorally

  Fistula
• May drain extraoral and intraoral depending on

  Muscle attachment

  Direction of roots

  Thickness of bone
• What are the muscle attachmeny

  mylohyoid and buccinator
• What are the muscle attachmeny

  mylohyoid and buccinator
• Muscle of the floor of the mouth

  Mylohyoid muscle
• Muscle of cheek

  Buccinator muscle
• If Maxillary drain below the muscle attachment

  Vestibule
• If maxillary drain above the muscle attachment

  Skin (extraoral swelling)
• If mandible drain below the muscle attachment

  Skin
• If mandible drain above the muscle attachment
