History
1- Ancient root canal filling: Nabatean warrior in 2200 years ago
(around 200 BC), 2.5 mm metal bronze wire inside the root canal.

warm from burrowing inside the canal.

History, diagnosis and treatment planning:
•Medical and dental history: Medical history should reveal any medical condition or medication which might influence diagnosis or treatment.
•Clinical examination: The patient should be examined both extra- and intraorally.
•Diagnosis: The cause of the patient’s complaint should be identified. Some or all, of the following diagnostic tests may be applied : palpation, mobility test, percussion, periodontal examination, occlusal analysis, testing for possible cracked teeth, pulp sensitivity tests, transillumination, selective local anaesthesia, radiography (normally by using the paralleling technique and a beam guiding device for good reproducibility), colour matching and sinus tract exploration.
•Treatment planning: It should be planned for those teeth that are functionally or aesthetically important and have reasonable prognosis.
