“…However, this study was limited by its small sample size ( N = 108) and they were from only one Veterans Administration Medical Center. There is a dearth of information on the attitudes and beliefs of smokers related to lung cancer screening . Identifying all barriers and facilitators for smokers is essential for promoting lung cancer screening for a high‐risk population.…”

The US Preventive Services Task Force recommends that smokers aged 55–80 should be screened annually with low‐dose computed tomography (LDCT). This study identified demographics, smoking history, health risk perceptions, knowledge, and attitudes factors of older smokers (≥55 years) related to LDCT agreement. Using binary logistic regression, a predictive model of factors to explain LDCT agreement was produced. This is a cross‐sectional, national, online survey of 338 older smokers (≥55 years) with a ≥30 pack‐year smoking history. Over 82% of the sample believed that a person who continues to smoke after the age of 40 has at least a 25% chance of developing lung cancer and 77.3% would “agree to a LDCT today”. Using chi‐square analyses, six variables that were significant at the 0.10 level were selected for inclusion in model development. Four of the independent variables made a unique statistically significant contribution to the model: perceives accuracy of the LDCT as an important factor in the decision to have a LDCT scan; believes that early detection of LC will result in a good prognosis; believes that they are at high risk for lung cancer; and is not afraid of CT scans. Of note, only 10.9% believed that a negative CT scan result would mean that they could continue to smoke. Older smokers are aware of the risks of smoking, are interested in smoking cessation, and most are interested in and positive about LDCT. Cognitive aspects of participation in screening are key to increasing the uptake of lung cancer screening among high‐risk smokers.

“…The stochastic effect is governed by the laws of probability; therefore, it may or may not occur, and a threshold does not exist. The low levels of ionizing radiation induced by CBCT do have the potential to cause stochastic effects and, thus, are a potential risk factor for carcinogenesis [20]. …”

“…Although E is mainly used in radiation protection, it has found large application in comparing exposure risk of only certain body regions, such as the maxillofacial region. The risk associated with CBCT imaging has mainly been compared to the radiation dose imparted by a standard panoramic radiographic procedure [20]. The E of a digital panoramic radiograph ranges from 0.004 to 0.030 mSv, whereas, depending on CBCT devices, published E levels vary from 0.027 to 1.073 mSv, an equivalent of 2–10 panoramic radiographs [2, 20].…”

An accurate E estimation was performed on different dental CBCT devices, using a large number of thermoluminescent dosimeters in the head-and-neck region to cover all radiosensitive structures [2].…”

Dental Cone Beam Computed Tomography in Children: Clinical Effectiveness and Cancer Risk due to Radiation Exposure

et al. 2019

Firstly used in the early 90s to generate 3-dimensional projections of X-ray images, cone beam computed tomography (CBCT) has resulted in a large application in dentomaxillofacial imaging, even in children. CBCT uses ionizing radiation that may cause damage to the DNA, and children are at the greatest carcinogenesis risk due to their higher tissue radiosensitivity and their longer life expectancy compared to adults. The questions of whether the cancer risk is really increased after repeated dental CBCT in childhood and of what the underlying biological basis is have become hot topics in the field of dentistry and radiobiology. We performed an overview of the current literature to assess an acceptable role of CBCT in pediatric dentistry.

ÖZETDental pratikte sıklıkla karşılaşılan Kırık diş sendromu, oluşturduğu şiddetli ağrı semptomlarını gidermek amacıyla hızlı teşhis ve tedavi yaklaşımı gerektiren bir problemdir. Bu olgu sunumunda; teşhisi ve tedavisi gecikmiş bir vaka sunulmaktadır.: Herhangi bir sağlık problemi olmayan 40 yaşındaki bir erkek hasta kliniğimize başvurdu. Hasta hikâyesinde özellikle çiğneme esnasında, ayrıca sıcak ve soğuk yiyecekler sırasında sağ üst dişlerinde elektrik çarpması tarzında ağrılar hissettiğini ve bu şikâyetlerine bir yıldır teşhis konulamadığını belirtti. Hastanın intraoral muayenesinde; dişlerde generalize atrizyon, abrazyon ve dişeti çekilmesi bulgularına rastlandı. Gözle muayene, transillüminasyon ve boyama yöntemleriyle maksiller 1. ve 2. premolarlar ve 1. molar dişlerin palatinal yüzeylerinde çatlaklar izlendi. Konik ışınlı bilgisayarlı tomografi incelemesinde maksiller 2. premolar dişte görülen çatlağın pulpaya ulaştığı izlendi.Isırtma testinde hassasiyet gözlenen ve hiperemik olan maksiller 2. premolar dişe kanal tedavisi uygulandı. Kontrol seanslarında hastamızın şikâyetlerinin tamamen kaybolduğu gözlendi. Çatlakların etyolojisinde rol oynayan bruksizmin tedavisi için koruyucu plak uygulaması önerildi. Hastamızın anksiyete bozukluğu psikiyatri uzmanına konsülte edildi.Anahtar Kelimeler: Kırık diş sendromu, Konik Işınlı Bilgisayarlı Tomografi, Dentin hassasiyeti, Bruksizm ABSTRACTCracked tooth syndrome is a problem frequently encountered in dental practice and requires immediate diagnosis and treatment in order to eliminate the symptoms of severe pain. In this report; a case of delayed diagnosis and treatment is presented.A 40-year-old male patient who had no health problem referred to our clinic. In his history, the patient complained about an electric shock-like pain in the right upper teeth especially during chewing, and also during eating cold and hot foods and also he stated that his complaints couldn't be diagnosed over a year. In intraoral examination; generalized attrition and abrasion, and gingival recessions of the teeth were detected. Cracks were observed on the palatal surface of maxillary first and second premolar, and first molar teeth, through visual inspection, transillumination, and staining methods. Examination of the Cone-beam Computed Tomography revealed that the crack of the maxillary fist premolar tooth reached the pulp.Root canal treatment was performed to the maxillary fist premolar tooth which had hyperemia and sensitivity to bite test. In the control sessions, it was observed that the complaints of the patient disappeared completely. Usage of a mouth guard was recommended for the treatment of bruxism which is taught to play a role in the etiology of the cracked tooth syndrome. Anxiety disorder of the patient was consulted to a psychiatrist.
