“…Study conducted in 2010 in Kuwait reported dose-response relationship between dental x-ray and thyroid cancer (Memon et al, 2010). Another study from Kuwait conducted in 2003 reported association between family history of benign thyroid disease and thyroid cancer (Memon et al, 2004).…”

“…The sample size found varied from 99 to 749 subjects except for one study conducted in Oman in which 36000 babies were diagnosed. The study population of these studies comprised of children of school age and adults: five studies were case control with sample size varying from 100 to 313 subjects (Akbar et al, 2006;Memon et al, 2002aMemon et al, , b, 2004Memon et al, , 2010; four of the studies were from Kuwait (Memon et al, 2002a(Memon et al, , b, 2004Memon et al, 2010); and one from Saudi Arab (Akbar et al, 2006) and the study population was recruited from hospitals in Kuwait and Saudi Arab, retrospectively, and eight studies were retrospective; three were from Yemenone from Iraq (Nasheiti, 2005), three from Saudi Arab and one from United Arab Emirate. The sample size was found to vary from 45 to 810 subjects and comprised of children and adults, and all data collected were hospital based.…”

Thyroid gland diseases are a public health problem worldwide. Imbalance in the regulation of thyroid gland hormones can cause many disorders that range from a small goiter to life threatening diseases, such as thyroid cancer. Thyroid dysfunction both hyper and hypothyroidism can affect circulatory system by affecting cardiac output, cardiac contractility, blood pressure, vascular resistance and rhythm disturbance which can further cause heart failure, fibrillation, congestive heart failure and blood pressure. Westernization and nutrition transition in Arab world have increased the burden of adenocarcinomas, including thyroid cancer. This review aims to present the aggregated burden, risk factors and prognosis of various thyroid diseases prevalent in Arab countries. An electronic databases search was conducted using PubMed in addition to searching of accessible local journals in Arab world, using keywords and terms like epidemiology, burden, odds, risks, etc. After applying exclusion and inclusion criteria, 21 articles were selected to include in this review. The review showed that the prevalence of different types of thyroid disease varied between the reported studies in Arab world ranging from 6.18 to 47.34% prevalence of goiter reported by several studies conducted in Arab world, such as Egypt, Algeria and Bahrain with 25.25, 86 and 1.7%, respectively. Gender, dietary factors, iodine deficiency, family history, diabetes and x-ray radiation were reported as risk factors associated with different type of thyroid diseases. The most prevalence of thyroid disease was concluded to be thyroid lesions which varied in different regions of Arab and the burden of thyroid cancer is very high and very common in different Arab region, and further longitudinal studies are still needed to investigate the prognosis and determinants of these thyroid diseases in the Arab world.

Introduction and Objective: This study aimed to evaluate the correlation between conventional and digital radiographic methods in the measurement of periapical lesions in primary molars and compares the time used to obtain the radiographic images between both methods. Material and methods: This crossover study included children between 4 to 8-year-old with periapical lesion in primary mandibular molars. Fifteen molars were randomly assigned firstly to receive conventional or digital periapical radiograph during the steps of endodontic treatment. The time to obtain the radiographic image was evaluated in seconds and compared by the Mann-Whitney test. The periapical lesions measurement (mm

“…12 Nonetheless, recent concerns over radiation risks associated with these procedures have also been raised in dentistry, 13 particularly in association with intracranial meningioma 14,15 and thyroid cancer. 16,17 Although the validity of these epidemiologic studies has been called into serious question, 18,19 the contribution of xray exposure from dentistry to per capita annual dose may well be increasing, as is the case in diagnostic imaging in general, which now accounts for almost 50% (3000 mSv) of annual per capita radiation dose in the United States (6200 mSv). 2 Perhaps the major contributing factor in the general rise of dose in dentistry has been the rapid rise in the availability and use of cone beam computed tomography (CBCT) in clinical practice.…”
