“…While radiographs give useful information, the radiation dose poses long-term radiation concerns. 5 Latest studies have proven that X-ray radiation from diagnostic imaging of the craniofacial region increases the risk of cancer. In a recent study on CBCT dosimetry by Ludlow et al, Qu et al, Hirsch et al using various CBCT machines from various manufacturers and different FOV settings, it was discovered that increasing the FOV height draws new and potentially radiosensitive tissues into the area of direct exposure, whereas increasing the width of the beam merely increases the dose to tissues already being exposed.…”

“…Conclusions: Using the ICRP 2007 tissue weighting factors, the effective dose of the new generation of CBCT scanner is lower than that of the original generation machine for an equivalent FOV. 5 Given that CBCT examinations routinely utilize higher doses of radiation than traditional diagnostic radiography, it becomes even more critical that everyone using this technology knows the rational explanation of patient exposure, optimizing the patient dose, and radiation safety practises of staff. It is crucial for oral and maxillofacial radiologists to understand and explain to their patients and referring practitioners the dose and related risk of specific investigations.…”

The development of cone-beam computed tomography (CBCT) technology altered the practise of oral and maxillofacial radiology. When compared to medical computed tomography, CBCT was quickly adopted in dentistry settings due to its small size, relatively reduced cost, and decreased ionising radiation exposure. CBCT referrals are still being made incorrectly due to a lack of sufficient education among dentists and specialists. Furthermore, in order to get high-quality pictures, operators may raise the radiation dose, exposing the patient to unnecessary hazards. The objective of this review is to give an insight into 3D imaging with CBCT technology and a prudent radiation monitoring during CBCT for the benefit of both patients and dentists.

“…Therefore, any radiographic investigation should provide a clear potential advantage to the patient, weighing the diagnostic benefits against the risk that the exposure might cause [1]. The risk of radiation comes to be a striking community concern, mainly when multiplied by the vast number of patients being exposed to diagnostic imaging, whereas the hazard from maxillofacial imaging for an individual is not particularly high [1] Since the radiographic examination is ranked as one of the most widely used examinations in investigative procedures in the last century, the focus on dose reduction to the patient is critical [2], for that reason, some attempts were made by machine manufactures in order to minimize the radiation dose to "As Low As Reasonably Achievable" or "As Low As Diagnostically Achievable" (ALADA) via implementation of certain practices and protocols [3]. The technical developments that were seen in the field of radiology protection in the past decade led to the development of this scientific research about this topic [4].…”

Background: Radiation protection in the dental examination is often overlooked because the doses delivered are negligible. However, the volume of dental radiological examinations will constitute almost 15% of all the radiological examinations carried out in the medical field. Aim: This study aims to evaluate and compare the surface equivalent dose on various target organs from various radiology devices on the RINN phantom, and the effect of numerous scanning protocols on said dose using dosimetry badge (Instadose). Objectives: The main objective is to study surface equivalent doses delivered in various critical organ regions in the facial region with the help of an Instadose device and to compare the doses delivered between 2D programs against 3D programs. Materials and Methods: RINN phantom was mounted on a dental chair for use against Planmeca ProMax 3D Classic and Planmeca intraoral ProX. Models. An Instadose badge was placed on various anatomical landmarks, and radiographic exposure protocols were applied to vary the parameters. The equivalent dose was calculated by connecting the dosimeter to a laptop and performing an instant reading output on the Instadose software. Results: The Thyroid showed a mean of 0.350, 0.0000, 0.0133, and 0.0000 in response to exposure by intraoral machine ProX, Panoramic, CBCT, and CBCT in ULD mode respectively. The dose absorbed by the left salivary glands was found to be significantly lower than the right salivary glands in panoramic exposures. Conclusion: It was revealed that a significant reduction in the dose when applying the Ultra-Low Dose protocol was noticed, and it reached up to 100% in the thyroid. It was also noted that there is no need for a thyroid collar in CBCT and Panoramic exposures. Maintaining the KVp at a constant and the exposure time as a variant caused a change in the dose equivalent received by the floor of the mouth and the right salivary gland.

Dentists are at risk of noise-induced hearing loss (NIHL). Dental treatment equipment has high-intensity noise levels. Occupational noise levels of multi-unit dental clinic are higher than private clinic and are at further increased risk of NIHL. This study aims to develop a noise-reducing appointment system in multi-unit dental clinics using treatment duration and steps noisemap. Restorative, periodontal, and prosthetic dental procedure noise levels were measured in a multi-unit dental clinic. A procedure noise map was created by measuring the amount of noise in the treatment time interval and the silent treatment period. The appointment algorithm was created according to this noise map. Control and 7 test simulation appointment algorithms were tested. The control group was simulated in six units simultaneously with conventional hour-based appointment algorithm. Test groups were simulated according to the appointment algorithm based on the treatment steps noisemap. Six-unit dental clinic was simulated under the dBmap system. While 2 of the 6 units in the test groups are in noise producing treatment steps, the other 4 seats are planned to operate without noise. According to treatment steps noisemap, test groups operated two-unit simultaneously at different timings. The distribution of noise producing units in the clinic was simulated in 7 groups (T1-T7). The mean noise measurements in all tested groups were significantly lower than in the control group. Periodontal treatment mean occupational noise level (68 dB) was higher than restorative (61 dB) and prosthetic treatment (59 dB). Control room mean occupational noise measurement was 68,54 dB, and test groups mean occupational noise measurements were between 57,19 –63,98 dB. The difference between control and tested groups was significantly different(p=0,0009). Occupational noise was significantly reduced with the noise reduction-based appointment method. Further studies are needed with different treatment procedures and validation studies in clinical settings.

Dosimetry in dentistry

Abstract: The present review on dosimetry based on various studies done with dosimeters revealed that, with the advent of radiographic technique the effective dose delivered is low. Therefore, selection of radiological technique plays an important role in dental dose delivery.
