Abstract
Emergence of coronavirus disease 2019 pandemic has had its effects on many aspects of life. The practice of oral and maxillofacial radiology has also been affected by the ongoing pandemic. This letter to editor highlights some of the challenges of oral and maxillofacial radiology during this era.

Dental practices have been affected by the coronavirus disease 2019 (COVID-19) outbreak and have mostly been limited to emergency treatments, such as management of pain and infection by endodontic or surgical approaches and treatment of patients with trauma [1]. Imaging plays an important role in this setting for appropriate diagnosis and treatment. Therefore, oral and maxillofacial radiology clinics need to adapt strategies to continue their services during this critical time.
Current evidence for avoiding cross infections in dentistry suggests to prefer extraoral radiography or cone-beam computed tomography (CBCT) over intraoral radiographs [2] since peri-apical radiographs are more prone to stimulate salivary production. If intraoral images are required, use of antimicrobial solutions before obtaining radiographs must be considered [3]. A mouth rinse of 1% hydrogen peroxide solution or 0.2% povidone-iodine is effective in reduction of the viral load in oral cavity [2]. During intraoral radiography, irritation of the palatal mucosa must be minimized to reduce the risk of gag reflex or coughing [4, 5]. Meticulous infection control procedures must be implemented for all radiographic procedures [6]. Moreover, the radiology unit needs to be well ventilated and conform to general requirements of dental offices [2].
Another important point is eliminating hard copies of radiographs. Films and papers can be a vehicle for cross-contamination when handled by individuals or placed on surfaces. Digital picture archiving and communication system (PACS) is a network of computers and servers used to manage digital images [7]. The PACS workflow is able to digitally transfer radiographic images to several users, thus eliminating the need for radiographic hard copies. Teleradiology is another technique defined as interpretation of radiographic images, which were obtained far from the facility. During the pandemic, teleradiology has been widely used for diagnostic purposes of COVID-19 patients, for consultations with radiologists in emergency cases, or management of distance between radiology clinics. Dentists can receive the digital radiographic images of their emergency patients through online services either by email or messaging applications to view in their smart phones, laptops, or other electronic devices. However, several factors must be taken into account for viewing radiographic images through these media. It is better to interpret images in a room with reduced ambient lighting [11] with optimized brightness of the screen. Most current smartphones provide adequate conditions for optimal image interpretation [12]. A key point in sending the radiographs using messaging apps or emails in ensuring the image quality is preserved during electronic transfer. Some studies have shown that images sent via these applications can be optimally interpreted [13, 14]. Another factor when using online platforms is security of the transferred data. Imaging data can be hijacked either from the recipient party or while transferring through insecure means. Using end-to-end encrypted transfer applications and paying attention to who has access to the device withholding patient protected information help to prevent such instances. In cases when a secure transfer environment cannot be achieved, patients’ images can be anonymized and coded by the sending party in the imaging center.
