A positive response to cold test indicates always healthy pulp |
True | False |

True | False |
For EPT, the tooth should be isolated from neighboring teeth and air-dried |

True | False |
Mucosal lesions (herpes, afta) can be confused with odontogenic pain |
In primary herpes the pain can begin before any clinical signs of a mucosal lesion |
True | False |
Parallel technique is preferred to taking endodontic radiographs |
Digital radiography: CCD sensors are faster than phosphor plates |
CCD-sensors should preferably be used with bisecting technique |
Digital radiographs can be edited to enhance viewing |
True | False |
A preoperative radiograph must always be available before endodontic treatment |
A fistulograph can give valuable information of the source of the infection |
Use of two different types of files (K, H, e.g.) is recommended for WL radiograph when two canals is present in one root |
Rubber dam should be removed when taking a radiograph |
True | False |
Ca 20% of teeth with irreversible pulpitis are symptomatic |
Pulpitis is always easily diagnosed. |
Canal obliteration may be a sign of chronic pulpitis |
Large apical lesion may be a sign of pulpitis |
True | False |
The pulp is usually vital |
A lesion in bone will usually be observed apically in the radiograph |
Ca. 80% of apical periodontitis cases are symptomatic |
The lesion can locate only laterally in some cases |
True | False |
A radicular cyst can be reliably diagnosed by a radiograph |
A radicular cyst can be reliably diagnosed histologically |
Radicular cyst is typically pear-shaped |
A tooth with a radicular cyst always has apical periodontitis |
A tooth with apical periodontitis always has a radicular cyst |
True | False |
Craze line usually requires invasive treatment |
True | False |
Crack tooth has separated fragments |
Crack tooth cannot occur in canines |
Crack tooth: fracture line starts in the crown area |
Crack tooth: fracture line is bucco-lingual |
True | False |
Split tooth has separated fragments |
Split tooth can usually be save by endodontic treatment |
True | False |
Typical radiographic shape of the lesion in vertical root fracture is round |
Typical radiographic shape of the lesion in vertical root fracture is pear shaped |
