Surgical Endodontics MCQs

Question no 1: the objective of incision and drainage are

  1. To evacuate exudates and purulence from a soft tissue swelling
  2. Incision for drainage increases discomfort
  3. Drainage through the soft tissue accomplished most effectively when swelling is firm and non- fluctuant
  4. Incision for drainage is always made horizontally into the swelling
  5. Incision of drainage speeds up healing process


Question 2: Peri apical surgery is indicated

  1. When there is persistent peri apical infection that cannot be resolved with non- surgical root canal re- treatment
  2. When there is true cyst
  3. Severe periodontal disease
  4. Irretrievable posts and root fillings and there removal would result in further damage to the root structure
  5. Unidentified cause of conventional root canal failure

Question 3: root end resection

  1. It removes the untreated apical portion of root
  2. It provides angled surface to prepare a root and cavity preparation
  3. It should be perpendicular to long axis of tooth
  4. It expose additional canals, apical deltas, or fractures
  5. It should be around 5 mm because most of additional canals are present in apical 5mm

Question 4: indication for root amputation or hemisection

  1. Preservation of strategically important roots and its accompanying crown
  2. Root fusion or proximity
  3. Untreatable roots with broken instruments, perforations, caries, resorption and calcified canals
  4. Severe periodontal disease
  5. Inability to complete root canal treatment on either half.

Question no 5: root end cavity preparation

  1. Are now made with ultrasonic tips
  2. Preparation should be class one type in the apical portion of canal
  3. It should have a minimum depth of 3mm
  4. It should have a minimum depth of 5 mm
  5. The walls of the preparation will be slightly oblique with long axis of the root

Question 6: Thirty year old patients presented to you with chief complain of chewing. Radiographic examination reveals furcation caries and bone loss that has compromised the distal root. Which surgical procedure will be indicated for management?

  1. Bicuspidization
  2. Hemisection
  3. Apical surgery
  4. After root canal treatment, crown will be divided through the furcation
  5. Root amputation

Acute Apical Abcess/Periapical Abscess/Periredicular Abscess:

It’s one of the painful dental emergency results from extension of bacterial infection from dead pulp into the periapical tissues.

Acute Apical Abscess are of Two types

  1. Diffuse
  2. localized

Case 1:

This the Periapical radiograph of 21 year old female showing radiolucency associated with periapex of first premolar. Tooth was very tender on percussion and patient had extra-oral swelling on left side of face.

Extra-Oral swelling on left side of face due to spread of infection from maxillary first premolar


Case 2:

Diffuse extra-oral swelling This is the picture of a 32 year old female patient came to emergency with chief complain of severe pain and extra-oral swelling on right side of face. On examination maxillary canine was carious, tender to percussion and slight mobility was present

Localized abscess

Localized abscess associated with maxillary 1st molar. Tooth was tender to percussion

Fluorosis

 

 

  • Increase exposure to fluoride during tooth formation will lead to dental fluorosis.
  • Normal optimum level of water fluoride is upto 1ppm
  • Increasesd level of fluoride more then 1ppm will cause fluorosis
  • Clinically it appears as white opaque areas to brown discoloration and pitting of enamal
  • In severe cases hypomineralised enamel becomes very fragile and undergo surface damage
  • Management of dental fluorosis varies according to severity
  • In Mild cases micro and macro-abrasions and bleaching are treatment options
  • In moderate cases composite restoration and veneers are treatment options
  • In severe cases full crowns

 

Case 1

A female patient aged 21 came to conseravtive department with the chief complian of discolored upper central incisor.discoloration is present since her childhood. Clinically the discolration is of mild grade according to dean’s index

Mild grade fluorosis

 

Case no 2

23 year ol female with the chief complain of discoloration and tooth surface loss in upper anterior region.On examination mild to moderate grade fluorosis according to dean’s index

Management with composite restoration

Broken / fractured endodontic instrument

Broken instrument is one of the procedural accidents that occurs during cleaning and shaping of root canal system.

Causes of broken instrument in root canal:

  1. Improper use of instrument
  2. Same instrument used for many times
  3. Excessive force applied to file during cleaning and shaping

    Prevention

    1. Lubrication of instrument with irrigating solution such as sodium hypochlorite or with lubricating agent EDTA (ethyl diamine tetra acetic acid)
    2. Instrument should be examined before use, if there is and untwisting in file which will be visible as shiny spot then it should be discarded
    3. Small no. of files must be discarded after single use.
    4. NiTi files do not show any sign of untwisting so they must be discarded before untwisting is seen

Management

There are three methods of management

  1. Make an attempt to remove it
  2. Attempt to bypass it
  3. Fill and obdurate it.

This is the radiograph of 25 year old male presented with pain in lower right and left 1st incisors. The teeth had been endodontically treated 2 years before. Periapical radiograph showed inadequate filled canals and periapical radiolucency associated with lower right and left 1st and 2nd incisors and broken instrument in left lower 1st incisor.

Dental Fistula: case reports with images

Dental Fistula/ Cutaneous Fistula of Dental Origin/ Suppurative Apical Periodontitis/ Apical Periodontitis With Fistula.

  • Dental fistula is a communication between the oral cavity and cutaneous surface of face
  • It is a squeal of infection from dental pulp that spread beyond the apex
  • Generally it is a painless condition because when drainage occurs, pressure relieves and symptoms disappear.
  • Chronic inflammation involves apical portion of tooth’s root.
  • Drainage mostly occur within oral cavity on facial or buccal side of alveolar ridge
  • Rarely occurs on cutaneous surface of face
  • Intraoral sinus tracts are common but extra oral fistula is not common.
  • Treatment involves complete debridement and obturation of root canal or Extraction.

Case 1:

This is the case of 10 year old patient with the chief complain of draining pustule from one month. Clinical examination reveals extraorally cutaneous draining fistula, intraorally grossly carious left mandibular 1st molar. Vitality test was negative. Radiographic findings are radiolucency associated with distal root of 1st molar and open apices. gutta percha point was used to trace the fistulas tract and was confirmed from radiograph it was associated with mandibular 1st molar. Diagnosis was chronic apical abscess or suppurative periodontitis with fistula.

Autotransplantation Of Tooth

23 year old female was referred for dental treatment with the chief complain of pain in mandibular right 1st molar. Clinically the tooth was grossly carious. Periapical radiograph revealed coronal caries involving pulp and periapical radiolucency associated with mesial root of mandibular 1st molar. From the history of pain and examination it was confirmed that patient had irreversible pulpitis so root canal treatment was performed.during access cavity preparation iatrogenic furcation area gets perforated and tooth was difficult to treat and extraction was indicated.mandibular 3rd molar of same site was clinically and radiographically sound and decision was made to transplant 3rd molar in place of extracted 1st molar.
