Prevalence of Carotid Artery Calcification Detected on Panoramic Radiographs of Patients with a History of Hypertension or Myocardial Infarction

Background: Atherosclerosis is characterized by the deposition of lipids on the internal walls of blood vessels, damaging various tissues of the body by complete or partial occlusion of the vessels. Sometimes the calcified plaques in the carotid artery can be detected on panoramic radiographs, helping the practitioners decrease the risk of Cerebrovascular Accident (CAV). Objective: This study aimed to assess the frequency of Carotid Artery Calcification (CAC) detected in panoramic radiographs of patients with hypertension or myocardial infarction. Methods: A total of 400 panoramic radiographs of patients >40 years of age were evaluated. The images belonged to patients with a history of hypertension or myocardial infarction and healthy individuals referred from the AL Zahra Cardiology Department to Isfahan School of Dentistry and a private oral and maxillofacial imaging center. All the images were evaluated for the presence of CAC. Data were analyzed with SPSS 19, using the Chi-squared test, Fisher's exact test, t-test and ANOVA (α=0.05). Results: The prevalence rate of CAC was 4%. According to the results, there was a significant relationship between CAC and hypertension (P=0.003), with no significant relationship between the prevalence of these lesions, stage of hypertension and myocardial infarction. Conclusion: According to the results, the prevalence of CAC on panoramic radiographs was significant; therefore, it seems that the detection of CAC on panoramic radiographs of patients must be considered by dentists.

ABSTRACTObjectives: The aim of this study is to determine retrospectively the presence of carotid artery calcifications (CACs) detected on panoramic radiographs (PRs) in a group of Turkish population. Further, the relationships between CACs and gender, life style, and medical history were evaluated.Methods:During the years 2004 to 2006, a random sample of 1282 PRs was collected from patients older than 40 years who were being treated by the School of Dentistry, Erciyes University. Of these 1282 PRs, 750 PRs were included in this study. Medical data was collected from the archival records of the dental school.Results: About 38 (5.06%) CACs were found on the PRs of 12 (4.5%) males and 26 (5.4%) females. The CAC prevalence was not significantly different between the males and females (P=0.583). These calcifications were unilateral in 26 (68.4%) and bilateral in 12 (31.6%) subjects. Of those in the positive group, there were 12 subjects (31.58%) with hyperlipidemia, 12 subjects (31.58%) with hypertension, 7 subjects (18.4%) with diabetes mellitus, 6 subjects (15.8%) with cardiovascular disease, and 6 subjects (15.8%) with smoking history.Conclusions: This study has the highest CACs prevalence in comparison to the other studies. Therefore, dentists caring for subjects with dental problems should carefully evaluate their PRs for the evidence of CACs, and refer them for medical evaluation as indicated. So, incidental findings could provide life-saving information. (Eur J Dent 2007;1:132-138)

Introduction. A cognitive model of aetiology of panic disorder assumes that people who experience frequent panic attacks have tendencies to catastrophically interpret normal and benign somatic sensations - as signs of serious illness. This arise the question: is this cognition specific for patients with panic disorder and in what intensity it is present in patients with serious somatic illness and in healthy subjects. Objective. The aim of the study was to ascertain the differences in the frequency and intensity of 'catastrophic' cognitions related to body sensations, and to ascertain the differences in the frequency and intensity of anxiety caused by different body sensations all related to three groups of subjects: a sample of patients with panic disorder, a sample of patients with history of myocardial infarction and a sample of healthy control subjects from general population. Methods. Three samples are observed in the study: A) 53 patients with the diagnosis of panic disorder; B) 25 patients with history of myocardial infarction; and C) 47 healthy controls from general population. The catastrophic cognitions were assessed by the Agoraphobic Cognitions Questionnaire (ACQ) and the Body Sensations Questionnaire (BSQ). These questionnaires assess the catastrophic thoughts associated with panic and agoraphobia (ACQ) and the fear of body sensations (BSQ). All study subjects answered questionnaires items, and the scores of the answers were compared among the groups. Results. The results of the study suggest that: 1) There is no statistical difference in the tendency to catastrophically interpret body sensations and therefore to induce anxiety in the samples of healthy general population and patients with history of myocardial infarction; 2) The patients with panic disorder have a statistically significantly more intensive tendency to catastrophically interpret benign somatic symptoms and therefore to induce a high level of anxiety in comparison to the sample of patients with the history of serious somatic illness (myocardial infarction) and the sample of healthy general population. Conclusion. The tendency to catastrophically interpret benign somatic symptoms and therefore to induce a high level of anxiety in patients with panic disorder, confirms the cognitive aetiology model of panic disorder and suggests that it should be the focus of prophylactic and therapeutic management of patients with panic disorder.

Medial Calcification

Background: Intracranial internal carotid artery calcifications (IICAC), considered a phenomenon within the spectrum of atherosclerosis and vascular aging, are frequently encountered in ischemic stroke patients. While intimal IICAC directly contributes to ischemic stroke pathophysiology, the medial counterpart is generally deemed as a risk factor for vascular end-points. Apart from aging and cardiovascular risk factors, the underlying pathophysiology that contributes to development of IICAC is not well understood; herein we studied the interplay between mineral and skeletal metabolism biomarkers, and IICAC presence and pattern. Methods: In a prospective series of 194 ischemic stroke patients (mean±SD age: 69±14 yr), blood samples were collected to determine calcium, phosphorus, magnesium, osteocalcin, parathyroid hormone, and vitamin D levels within 72 hours of symptom onset. IICAC presence and type was determined on admission CT-angiography source images; a medial or intimal type of IICAC category was assigned according to Kockelkoren criteria. Results: A total of 45 (23%) patients had no calcifications, while 95 (49%) had an intimal pattern and 54 (28%) had non-intimal (or medial) pattern. Apart from the well-known factors related with IICAC, such as age, lower glomerular filtration rate (GFR), history of hypertension, diabetes mellitus, coronary artery disease and atrial fibrillation, we identified admission magnesium levels to be associated with IICAC presence and pattern (no calcification: 1.96±0.18 mEq/L, intimal calcification 1.93±0.19 mEq/L, medial calcification: 1.81±0.28 mEq/L; p=0.006). None of the other biomarkers had any significant relationship to IICAC. In multivariate models, a lower magnesium level was significantly associated with medial calcification (each 0.1 mEq/L drop increased the odds by 1.2 (95% CI 1.0-1.4; p=0.046)), in addition to older age, history of diabetes mellitus and lower GFR. Conclusion: Hypomagnesemia is one of the factors well-known to be associated with vascular calcifications in the body. Our findings, extend this relationship to the intracranial vascular bed. No similar association was observed for other biomarkers related to mineral and skeletal metabolism. (Funding: TUBITAK grant 218S753)

Objective: To evaluate the association between alveolar bone loss (ABL) detected on panoramic radiographs and carotid artery calcification (CAC) detected on computed tomography (CT). Methods: The study subjects included 295 patients (mean age ± SD: 64.6 ± 11.8 years) who visited the Matsumoto Dental University Hospital. The rate of ABL and the number of present teeth were measured on panoramic radiographs. Univariate analyses with t-tests and chi-squared tests were performed to evaluate the differences in age, gender, history of diseases, number of present teeth, and the ABL between subjects, with and without CAC. Moreover, multivariate logistic regression analysis, with forward selection and receiver operating characteristic curve (ROC) analysis, was performed. Results: The number of subjects without and with CAC was 174 and 121, respectively. Univariate analyses revealed that CAC was significantly associated with age, hypertension, osteoporosis, number of present teeth, and ABL. Multivariate logistic regression analysis adjusted for covariates revealed that the presence of CAC was significantly associated with ABL (OR = 1.233, 95% CI = 1.167–1.303). In the ROC analysis for predicting the presence of CAC, the the area under the ROC curve was the highest at 0.932 (95% CI = 0.904–0.960) for ABL, which was significant. Conclusions: Our results suggest that the measurement of ABL on panoramic radiographs may be an effective approach to identifying patients with an increased risk of CAC.

Abstract Carotid artery disease has been linked with cerebral vascular accident, also known as stroke, cerebral hemorrhage, or cerebral ischemia. It is caused by narrowing or obstruction of arteries in the neck (the carotid arteries) that are responsible for transporting blood from the aorta to the brain. Panoramic radiographs are used in dentistry to show both dental arches as a supplement to the clinical dental examination. The objective of this study is to highlight the importance of panoramic radiographs for diagnosis of arterial disease, by means of a bibliographic review. The PubMed database was searched using the keywords “atherosclerosis” and “panoramic”, with the filters “last 5 years” and “humans”. Twenty articles were identified, six of which were chosen for this study because they were open access. The review concluded that panoramic radiographs enable early diagnosis of carotid artery calcification, resulting in earlier interventions, and offer an accessible cost.

Background: Today, the use of dental radiography equipment in dental centers has increased due to its high application in the diagnosis of dental diseases. As a result, concerns are increasing regarding repeated exposure to this low dose level of radiation. Therefore, the knowledge and practice of dentists about radiation protection are essential for themselves and the patients. This study aimed to assess the knowledge and practice of dentists about radiation protection. Materials and Methods: This cross-sectional study was performed based on a questionnaire in several cities of Iran. The first part of the questionnaire included such information as gender, years of work experience, and participation in radiation protection workshops. The second, third, and fourth sections consisted of questions on radiobiology, radiation protection, and performance, respectively. Results: In this study, 94 dentists participated, and the mean scores of dentists (out of 5 points) for radiobiology knowledge, radiation protection knowledge, and performance were obtained at 2.66±1.1, 2.80±1.01, and 2.87±1.37, respectively. The results of Pearson analysis showed that general knowledge had a significant relationship with performance (P=0.014). There was also a significant relationship between the history of participation in radiation protection workshops and performance (P=0.01). Conclusion: It was found that more knowledge about the effects of ionizing radiation on the body and more awareness of the principles of radiation protection would help dentists to better observe the practical principles of radiation protection. Also, participating in radiation protection workshops could increase dentists' knowledge, and therefore, improve their performance.
