When and how do endodontic specialists use cone-beam computed tomography?

Area of Science:

• Dentistry
• Radiology
• Endodontics

Background:

• Cone-beam computed tomography (CBCT) is an advanced imaging technique increasingly utilized in dentistry.
• Its specific application and frequency among endodontic specialists in different European countries remain areas for investigation.

Purpose of the Study:

• To investigate the utilization patterns of CBCT by endodontic specialists and dentists with advanced endodontic training in Germany and Switzerland.
• To analyze the influence of endodontic qualification and case difficulty on the timing and frequency of CBCT use.

Main Methods:

• A questionnaire-based survey was distributed to German endodontic specialists (G-ES), Swiss endodontic specialists (CH-ES), and dentists with a German Master of Science in endodontics (MSc).
• Data collected included diagnostic assessment timing, endodontic case difficulty, and indications for CBCT.
• Frequencies of periapical radiography and CBCT use (pre-, intra-, and postoperative) were analyzed in relation to case difficulty levels.

Main Results:

• Access to a CBCT device was significantly associated with increased pre- and intraoperative CBCT use in high difficulty endodontic cases.
• The type of endodontic qualification significantly impacted the rate of preoperative CBCT use in complex cases.
• German endodontic specialists reported higher rates of preoperative CBCT use compared to Swiss endodontic specialists and MSc holders.

Conclusions:

• CBCT is a valuable diagnostic and treatment imaging tool for endodontists, particularly in managing high difficulty cases.
• The availability of CBCT technology and specialized endodontic training influence its adoption and application in clinical practice.
