Abstract

This study reviewed the literature on cone-beam computerized tomography (CBCT) imaging of the oral and maxillofacial (OMF) region. A PUBMED search (National Library of Medicine, NCBI; revised 1 December 2007) from 1998 to December 2007 was conducted. This search revealed 375 papers, which were screened in detail. 176 papers were clinically relevant and were analyzed in detail. CBCT is used in OMF surgery and orthodontics for numerous clinical applications, particularly for its low cost, easy accessibility and low radiation compared with multi-slice computerized tomography. The results of this systematic review show that there is a lack of evidence-based data on the radiation dose for CBCT imaging. Terminology and technical device properties and settings were not consistent in the literature. An attempt was made to provide a minimal set of CBCT device-related parameters for dedicated OMF scanners as a guideline for future studies.

Materials and methods

The literature regarding CBCT imaging in the OMF region was systematically reviewed. A PubMed search (National Library of Medicine, NCBI, New Pubmed System; revised 1 December 2007) was conducted from 1 January 1988 to 1 December 2007. 11 central keywords (Table 1) related to CBCT were used in combination with a total of 50 additional keywords (Table 1) to limit the search to CBCT imaging of the OMF region with dedicated CBCT scanners. These key words were used as search terms in multiple

Results

177 papers were analyzed. 86 papers (49%) were related to clinical applications, 65 (37%) to technique, 16 (9%) to radiation dose and 26 (15%) were synopsis papers (Table 3).

Discussion

Since the introduction of dedicated dento-maxillofacial CBCT scanners in the late 1990s6, 111, there has been an explosion of interest in these devices in the field of OMF surgery, orthodontics and dentistry. In the last decade, the number of CBCT related papers published each year has increased (Fig. 1). This results in a vast amount of literature. A systematic review of the literature related to CBCT imaging of the OMF region was undertaken to evaluate the indications, benefits and drawbacks
