Frequency of craniofacial pain in patients with ischemic heart disease

Referred craniofacial pain of cardiac origin might be the only symptom of ischemic heart accidents. This study aimed to determine the frequency of craniofacial pain in patients with ischemic heart disease. This cross-sectional study was accomplished on 296 patients who met the criteria of having ischemic heart disease. Data regarding demographics, medical history and referred craniofacial pain were recorded in data forms. In addition, patients underwent oral examination to preclude any source of dental origin. Chi-square test, Student’s t-test and backward regression model were used to analyze the data by means of SPSS software version 21. P<0.05 was considered significant. A total of 296 patients were studied comprising of 211 men (71%) and 85 women (29%) with the mean age of 55.8. Craniofacial pain was experienced by 53 patients out of 296, 35 (66%) of whom were male and 18 (34%) were female. None of the patients experienced craniofacial pain solely. The most common sites of craniofacial pain were occipital and posterior neck (52.8%), head (43.3%), throat and anterior neck (41.5%) respectively. We found no relationship between craniofacial pain of cardiac origin with age, diabetes, hypertension, and family history. On the other hand, there was a significant relationship between hyperlipidemia and smoking with craniofacial pain of cardiac origin. Radiating pain to face and head can be expected quite commonly during a cardiac ischemic event. Dental practitioners should be thoroughly aware of this symptomatology to prevent misdirected dental treatment and delay of medical care

Geochemistry and source of tourmaline from the Soheyle-Pakuh granitoid body (North of Nain)

The Oligocene Soheyle Pakuh granitoid body is located in the Urumieh- Dokhtar zone, which composed predominately of granodiorite, diorite and granite with mafic, aplite dikes and iron-tourmaline veins. On the base of geochemical characteristics, the composition of the tourmalines is schorl-dravite series with more tendency toward schorl component. The R1+R2 versus R3 diagram as well as by changing the tuormaline composition from Schorl to Dravite, depletion from alkali increases. Using of the Ca-Fe-Mg and Al-Fe-Mg ternary diagrams display that the The tourmalines from the Soheyle Pakuh granitoid body associated with quartz- tourmaline, meta- pelites, ca- depleted meta- psamite and meta- pelites associated with Al-phase. Oscillatory chemical zoning in the tourmaline crystals by increasing of Mg, Na and Al values in the rims than to the core, point to effect of the hydrothermal fluids. The substitution process in the structure of the tourmalines Soheyle Pakuh granitoid body mostly in accordance with the AlNa-1Mg-1,lOMg-1(OH)-1 AlOR2+ -1(OH)-1, Al(NaR)-1 FeAl-1exchange vectors. Since, the FeO/FeO+MgO ratio for is limited to 0.60-0.79 values, therefore, their source may be supposed by the way from magmatic system to a hydrothermal environment

Relationship of Chemical Composition of Saliva, Body Mass Index, and Nutrition with Permanent First Molar Caries in 6–12 Years Old

BACKGROUND: Dental caries is a major health problem worldwide, which negatively affects the quality of life. The salivary concentration of calcium, phosphorus, pH, and flow rate of the saliva plays a role in its cariostatic activity. AIM: This study aimed to assess the relationship of biochemical composition of the saliva, body mass index (BMI), and nutrition with permanent first molar caries in 6–12 years old. MATERIALS AND METHODS: This descriptive, cross-sectional study was conducted on 47 children between 6 and 12 years with four fully erupted first molars. Their weight and height were measured and BMI was calculated. Dental examination was performed, saliva sample was collected, and a questionnaire was filled out. Data were analyzed using the SPSS version 21. RESULTS: A significant association was noted between BMI and caries (p = 0.002). The association between caries and frequency of drinking soft drinks per week (p = 0.002), frequency of eating sugary foods per week fast food per month (p = 0.001), saliva pH (p = 0.001), and saliva flow rate (p &lt; 0.0001) was statistically significant. Although a significant association was noted between BMI and pH, saliva flow, and dental caries, no significant association was found between the composition of saliva (level of calcium and phosphate) with dental caries and BMI (p &gt; 0.05). CONCLUSION: It appears that reduction in saliva flow and pH and high sugar intake in overweight subjects increase the risk of caries. Further studies on a larger sample size are required to evaluate the role of other constituents of saliva in this respect

Posthaste Outgrow of Lip Pyogenic Granuloma after Diode Laser Removal

Introduction: Pyogenic granuloma (PG) is one of the inflammatory hyperplasia seen in the oral cavity. It is a reactional response to minor trauma or chronic irritation and also might be related to hormonal changes. Rarely, PG occurs extragingivally.The most common treatment of PG is surgical excision but alternative approaches such as laser excision have also been proposed.Case report: Herein, we present a case of lip pyogenic granuloma in a 15-year-old male whom had been under orthodontic treatment. The lesion was first excised with diode laser as a conservative method, but the lesion had immediately recurred and was excised with surgical blade as the traditional method. No recurrence or scarring was observed in 6 months follow-up.Results and conclusion: Although the use of laser as modern medicine offers a new tool for treatment of oral lesions, scalpel (blade) surgical excision still seems to be the successful treatment of choice in minimizing the recurrence of lesion especially when exacerbating factors such as hormonal imbalances exist

Oro-facial manifestations of 100 leprosy patients

Objectives: To verify the frequency of oral and facial involvement in diagnosed leprosy patients. Study design: This study was performed on 100 leprosy patients (62 male, 38 female, mean ages 51.86±6.1). After explaining the study design, we studied descriptive information including: patient?s sex, age, job, place of birth, familial history of leprosy, types of disease (lepromatous, borderline and tuberculoid leprosy), ocular and oral lesions, facial involvement and neuropathy. The statistical signification was measured by chi-square test. Results: A total of 46 (23 lepromatous, 15 borderline, and 8 tuberculoid leproy) out of 100 patients with leprosy had oral lesions. Statistical analysis did not show any significant difference in frequency of oral lesions between different types of disease. Facial lesions were presented in 57 (39 lepromatous, 10 borderline, and 8 tuberculoid leprosy) patients. There was a statistical significant difference in frequency of facial manifestations between different types of leprosy. It has to be mentioned that, atrophy of nasal spine, facial nerve involvement, ocular lesions and facial deformity were seen in 15%, 17%, 22% and 44% of leprosy patients, respectively. Conclusion: Examination of leprosy patients should be extended to the oral mucosa because oral mucosa may be a secondary source of M.Leprae transmission and infectio

Digital Radiography with Computerized Conventional Monitors Compared to Medical Monitors in Vertical Root Fracture Diagnosis

Introduction: Vertical root fracture (VRF) is a complication which is chiefly diagnosed radiographically. Recently, film-based radiography has been substituted with digital radiography. At the moment, there is a wide range of monitors available in the market for viewing digital images. The present study aims to compare the diagnostic accuracy, sensitivity and specificity of medical and conventional monitors in detection of vertical root fractures. Material and Methods: In this in vitro study 228 extracted single-rooted human teeth were endodontically treated. Vertical root fractures were induced in 114 samples. The teeth were imaged by a digital charge-coupled device radiography using parallel technique. The images were evaluated by a radiologist and an endodontist on two medical and conventional liquid-crystal display (LCD) monitors twice. Z-test was used to analyze the sensitivity, accuracy and specificity of each monitor. Significance level was set at 0.05. Inter and intra observer agreements were calculated by Cohen’s kappa. Results: Accuracy, specificity and sensitivity for conventional monitor were calculated as 67.5%, 72%, 62.5% respectively; and data for medical grade monitor were 67.5%, 66.5% and 68% respectively. Statistical analysis showed no significant differences in detecting VRF between the two techniques. Inter-observer agreement for conventional and medical monitor was 0.47 and 0.55 respectively (moderate). Intra-observer agreement was 0.78 for medical monitor and 0.87 for conventional one (substantial). Conclusion The type of monitor does not influence diagnosis of vertical root fractures

Coincidence of Compound Odontoma and Cemento Ossifying Fibroma; A Rare Case Report

Objective: Cemento-ossifying fibroma defines as a relative rare osteogenic neoplasm of the jaw. This tumor includes fibrous and osseous components. Odontoma is the most common odontogenic tumor containing enamel ,dentin ,cementum and pulp tissue. in this paper we report a  rare case of ossifying fibroma associated with compound odontoma in the mandible. Case: A 37-years-old woman was referred to Oral Medicine department , Shahid Beheshti Dental School with complaint of swelling in the anterior part of the mandible, over 6 years period. Clinical examination revealed mandibular enlargement in right –anterior region with labial and lingual expansion and canine missing . panoramic view showed a large mixed radiolucent -  radiopaque lesion associated with impacted canine.The differential diagnosis include calcifying odontogenic cyst (COC) and cemento-ossifying fibroma(COF). Histopathologic examination established diagnosis of COF with multiple compound odontoma .Conclusion: The relationship between the occurrence of these two lesions is not clear and more studies are needed to establish the relationship between them

Opium use and risk of bladder cancer: a multi-centre case-referent study in Iran

Background Bladder cancer (BC) is the 10th most common type of cancer worldwide and the fourth most common type of cancer in Iran. Opium use is considered as one of the risk factors for BC. We aim to assess the association between various parameters of opium use, which in Iran is mainly ingested or smoked in various forms, and the risk of BC. Method In this multi-centre case-referent study in Iran, 717 BC cases and 3477 referents were recruited to the study from May 2017 until July 2020. Detailed histories of opium use (duration, amount, frequency) and potential confounders were collected by trained interviewers. Multivariable unconditional logistic regression models were used to measure adjusted odds ratio (OR) and 95% confidence intervals (CI). The ORs were adjusted for age, gender, place of residence and pack-years of cigarette smoking. Results Regular opium consumption was associated with an increased risk of BC (OR 3.5, 95% CI: 2.8, 4.3) compared with subjects who never used opium. Compared with continuous users, the risk decreased to one-third for those who stopped opium more than 10 years ago. The adjusted OR for those who used both crude opium (teriak) and opium juice was 7.4 (95% CI: 4.1, 13.3). There was a joint effect of opium and tobacco (OR for users of both opium and tobacco 7.7, 95% CI: 6.0, 9.7). Conclusions Regular opium use is associated with an approximately 4-fold risk for BC. The OR decreases along with the increasing time since stopping opium use
