“…Also, AP extension and the size, location and spatial relationship with adjacent structures are properly assessed in CBCT images. 7,9 CBCT examination generates radiation exposure to the patient, which is higher than conventional panoramic or periapical radiographs, and lower than medical CT scans. 10 The limitations of 2D radiographs and the higher radiation dose of medical CT scanners should be considered in order to respect the ALARA (as low as reasonably achievable) principle and avoid unnecessary radiation exposure without clinical need or benefit.…”

Objectives: The aim of this study was to determine the prevalence of apical periodontitis (AP) detected in cone beam CT (CBCT) images from a database. Methods: CBCT images of 300 Brazilian patients were assessed. AP images were measured in three dimensions. Age, gender, number and location of total teeth in each patient were considered. AP location was considered according to tooth groups. The extent of AP was determined by the largest diameter in any of the three dimensions. Percentages and the x 2 test were used for statistical analysis. Results: AP was found in 51.4% of the patients and in 3.4% of the teeth. Higher prevalence of AP was found in 60-to 69-year-olds (73.1%) and in mandibular molars (5.9%) (p , 0.05). Inadequate endodontic treatment presented higher prevalence of AP (78.1%). Conclusions: AP can be frequently found in CBCT examinations. The presence of AP has a significant association with patients' age, and tooth type and condition. CBCT databases are useful for cross-sectional studies about AP prevalence in a population.

“…With regard to apical surgery, Velvart et al (9) reported that CT scans aided in determining the relationship of lesions to the mandibular canal before apical surgery. With regard to these findings, CT has been considered a valuable tool for diagnosis and treatment planning in conventional and surgical endodontic therapy (10). Nevertheless, the use of CT imaging in dentistry has always been limited because of cost, access, and exposure to radiation (11).…”

“…Other, future and current situations where a successful outcome could be measured with 3D imaging in endodontics include healing after apical surgery healing after trauma with alveolar fractures or luxation injuries , stabilization of resorptive defects , healing of inflammation and membrane thickening in paranasal sinuses and healing of furcal or lateral defects after perforation repair .…”

“…The usefulness of three‐dimensional techniques for the detection of periapical osseous lesions has been described specifically when preparing for surgical endodontics . Indeed, well‐documented limitations of two‐dimensional radiographic techniques such as conventional periapical films make 3D assessment of periapical lesions attractive (Fig. ).…”

To be able to determine if endodontic treatment of apical pathosis is successful or not, healing of lesions is followed up by radiographic imaging. This can be done by observing changes in apical radiolucencies. Recently, cone beam computed tomography (CBCT) has been introduced as a method of gaining an unabridged view of dental anatomy, thus eliminating some of the most prevalent problems, such as superimposition and distortion. CBCT reduces false diagnosis and is rapidly replacing other radiographic techniques in diagnosis, quality control of treatment methods and techniques, and outcome assessment. Healing assessment using conventional and newer three‐dimensional imaging includes, but is not limited to, periapical osseous lesions, conditions of the maxillary sinus, status after endodontic surgery, hard tissue deposition in regeneration procedures, and horizontal root fractures. Due to a low predictive value of two‐dimensional periapical radiographs to distinguish between periapical disease and health, future assessment of endodontic treatment efficacy may include 3D imaging from small field‐of‐view CBCT units.
