“…However, the osteolytic lesions are not usually located in periapical regions, but in the posterior teeth region, ramus, and condyle (25). As regards evaluating endodontic variables using panoramic radiographs (PAN), this technique is a simple tool for diagnosing apical periodontitis because of its easy acquisition, low radiation dose, and panoramic views, as mentioned by Nardi et al (26). Furthermore, two-dimensional imaging (PAN and periapical radiography) is commonly accepted as a method for the diagnosis of AP, while three-dimensional imaging (conebeam computed tomographic (CBCT)) represents a second evaluation step in some cases (26,27).…”

Due to the immunosuppression status of these patients (28), inclusion and exclusion criteria were strictly applied and patients with other malign or hematological diseases were excluded, in order to reduce the effect of covariables.…”

Background: Previous reports have been analyzed the prevalence/association of apical periodontitis (AP) with systemic diseases. The present study aims to analyze the prevalence of healthy/diseased periapex and endodontic treatments in patients with Multiple Myeloma (MM) and compare the results with those of control subjects. Material and Methods: Panoramic radiographs of 50 individuals with MM were evaluated and compared with 50 controls that were sex and age matched exactly with the diseased group. Radiographic analysis was performed by two experienced endodontists under standardized conditions. The periapical status (presence or not of AP) was assessed using the periapical index (PAI). Data included systemic health, technical quality of root fillings, total number of teeth, quality of restoration, and periapical status. Statistical evaluation of differences between groups used chi-squared tests and Fisher's exact tests. Results: The prevalence of root canal-treated teeth was 10.11% in the MM group and 12.05% in the control group (p=0.90). The average root canal-treated teeth in the test group was 2,34 and 2.48 in the control group, where the difference was statistically significant (p=0.05). AP in 1 or more teeth was found in 86 % and in 78% of the patients in the MM and the control groups, respectively. When analyzed by subject, there was no statistically significant difference in the prevalence of AP (p>0.72). Similarly there was also no statistically significant difference in the prevalence of PA (p=0.85), when analyzed by tooth, AP was found in 63.2% and 62.9% in MM and control groups. Conclusions: The presence of AP and endodontic treatment was not significantly different in individuals with MM compared with control subjects. Future studies are needed to elucidate and confirm the association between MM and AP.

“…It has much higher sensitivity than the three aforementioned X-ray view series for the detection of mandibular fractures (70-92% and 66%, respectively) [1,8]. Unfortunately, both PAN and X-ray views are affected by the typical disadvantages of two-dimensional imaging [9]-difficulty in the patient's positioning, anatomic noise, superimposition, geometric distortion, X-ray angulations, and radiographic contrast-and may be burdened by the slight movements of the mandible, resulting in artefacts. This is the reason why two-dimensional imaging of mandibular fractures is usually limited to isolated lesions.…”

Mandibular fractures are among the most common maxillofacial fractures observed in emergency rooms and are mainly caused by road accidents. The clinical features of mandibular fractures include malocclusion and loss of mandibular function. Panoramic radiography is usually limited to isolated lesions, whereas computed tomography is the tool of choice for all other facial traumatic events. No reference standard classification system for the different types of mandibular fractures is defined. Therapeutic options include a conservative approach or surgical treatment based on the anatomic area and the severity of fracture. The main purpose of this pictorial review is to illustrate a practical description of the pathophysiology of mandibular fractures and describe both the imaging techniques to recognise them and the therapeutic indications.

“…Bitewing images can only visualize the crowns of posterior teeth with simple layouts and considerably less overlaps [17]. Panoramic radiographies are very common in dentistry, because they allow for the screening of a broad anatomical region and at the same time, require a relatively low radiation dose [18].…”

Neural networks are increasingly being used in the field of dentistry. The aim of this literature review was to visualize the state of the art of artificial intelligence in dental applications, such as the detection of teeth, caries, filled teeth, crown, prosthesis, dental implants and endodontic treatment. A search was conducted in PubMed, the Institute of Electrical and Electronics Engineers (IEEE) Xplore and arXiv.org. Data extraction was performed independently by two reviewers. Eighteen studies were included. The variable teeth was the most analyzed (n = 9), followed by caries (n = 7). No studies detecting dental implants and filled teeth were found. Only two studies investigated endodontic applications. Panoramic radiographies were the most common image employed (n = 5), followed by periapical images (n = 3). Near-infrared light transillumination images were employed in two studies and bitewing and computed tomography (CT) were employed in one study. The included articles used a wide variety of neuronal networks to detect the described variables. In addition, the database used also had a great heterogeneity in the number of images. A standardized methodology should be used in order to increase the compatibility and robustness between studies because of the heterogeneity in the image database, type, neural architecture and results.
