Women in Maxillofacial Surgery and Otolaryngology; Career Obstacles and Success Factors.

ABSTRACT: Little is known on career factors and expectations for female oral and maxillofacial surgeons (OMFS) in developing countries. The study aimed to explore career perceptions of females in 2 related surgical specialties: oral and maxillofacial surgery and otolaryngology (ENT) with a focus on career obstacles and success factors. A structured questionnaire was distributed to female surgeons working in Jordan in the 2 surgical specialties. Questions addressed socio-professional characteristics and career-promoting and hindering factors. All surgeons registered in both specialties were invited. A total of 56 surgeons participated in the survey. Age range was 29 to 55 years (mean = 38.55 ±â€Š5.799). Significantly more OMFS surgeons were single (P = 0.000) younger (P = 0.003), and had fewer years of experience (P = 0.01) than ENT surgeons. Significantly more ENT surgeons perceived the "hard working" attribute and "better communication skills" as career-promoting factors (P = 0.04, P = 0.015, respectively). Further, significantly more ENT surgeons believed that females in the surgical profession help in changing the traditional surgical stereotype linked with the male gender (93.8% ENT in contrast to 75% OMFS, P = 0.047), and expressed a preference for female mentors (48% ENT in contrast to 0% OMFS, P = 0.000). The results of this study indicate that female OMFS surgeons have different socio-professional characteristics and perceptions to their peers in ENT surgery, and this mainly manifested in professional experience, marital status, and important career perceptions. They seem to lack confidence in female participation and promotion of the surgical career, and they show preference for having exclusively male mentors.

Assessment of final-year medical students' performance in diagnosing critical findings on chest X-ray.

PURPOSE: Due to the recently emerging shortage in medical staff during the novel corona virus pandemic, several countries have rushed their undergraduate medical students into the emergency department. The accuracy of diagnosing critical findings on X-rays by senior medical students is not well assessed. In this study, we aim to assess the knowledge and accuracy of undergraduate final-year medical students in diagnosing life-threatening emergency conditions on chest x-ray. METHOD: This is a cross-sectional nationwide survey across all medical schools in Jordan. Through an electronic questionnaire, participants were sequentially shown a total of six abnormal X-rays and one normal. For each X-ray, participants were asked to choose the most likely diagnosis, and to grade the degree of self-confidence regarding the accuracy of their answer in a score from 0 (not confident) to 10 (very confident). RESULTS: We included a total of 530 participants. All participants answered at least six out of seven questions correctly, out of them, 139 (26.2%) participants answered all questions correctly. Pneumoperitoneum was the highest correct answer (93.8%), whereas flail chest was the least correctly answered case with only 310 (58.5%) correct answers. Regarding self-confidence for each question, 338 participants (63.8%) reported very high overall self-confidence level. Answers related to tension pneumothorax had the highest confidence level. CONCLUSION: Senior Jordanian medical students showed good knowledge with high confidence levels in diagnosing life-threatening conditions on chest x-rays, supporting their incorporation in the emergency department during pandemics and confirming the reliability of information they can extract.

Impaction of lower third molars and their association with age: radiological perspectives.

BACKGROUND: Third molars are the most commonly impacted teeth, and their extraction is the most commonly performed procedure in oral and maxillofacial surgery. The aim of the present study is to describe the pattern of mandibular third molar impaction and to define the most appropriate age for prophylactic extraction of mandibular third molar teeth. METHODS: A total of 1198 orthopantomographs (OPGs) with 1810 impacted lower third molars were reviewed by two authors. The pattern of eruption in relation to patient's age was examined using standard radiographic points and angles. Statistical analysis was performed using SPSS for Windows release 16.0 (SPSS Inc., Chicago, IL, USA). RESULTS: In patients older than 20 years, vertical pattern of impaction was the most common (21.4%); while in young patients; horizontal impaction was more common (21.3%). Furthermore, there was a constant pattern of increase in Pell-Gregory ramus class 1 with increasing age, as the prevalence of class 1 was 0% at age 18 years compared to 54.9% at the age of 26 years. CONCLUSION: Frequency of vertical impaction of lower third molars was seen more at an older age (> 20 years) in this study, with an increase in the retromolar space. Late extraction of mandibular third molar teeth (i.e. after the age of 20) is therefore recommended when prophylactic extraction is considered.

Dental students' knowledge and attitudes toward patients with epilepsy.

BACKGROUND: Inadequate knowledge and negative attitudes toward epilepsy can affect the provision of health services for patients with epilepsy. AIM: The aim of the present study was to assess the knowledge and attitudes toward epilepsy among clinical dental students in Jordan. METHOD: The study was conducted using a 21-item questionnaire to assess professional experience with epilepsy, knowledge about epilepsy, social tolerance, and willingness to care for patients with epilepsy among dental students at the University of Jordan. RESULTS: More than one-third of dental students believed that epilepsy is due to insanity or mental illness. Only 45% were able to identify convulsion or shaking as a sign of epilepsy, and more than one-third did not know how to act in case of an epileptic seizure in the dental clinic. Disappointingly, 43.4% of the respondents were of the opinion that people with epilepsy should not have children, and only 38.6% thought that people with epilepsy should be employed at the same jobs as other people. About 50% indicated that their families would be concerned about them treating patients with epilepsy, and 30% believed that knowing that patients with epilepsy were treated in their clinic might make other patients reluctant to continue their treatment there. CONCLUSION: The results revealed an inadequate level of knowledge and negative attitudes toward epilepsy among dental students at the University of Jordan. There is an urgent need to educate dental students about epilepsy.

Patients' perception of cross-infection prevention in dentistry in Jordan.

PURPOSE: To explore the public perception of cross-infection prevention methods and their role in disease transmission, among patients attending Jordan University Hospital. MATERIALS AND METHODS: A systemic random sample of 310 dental patients with a mean (SD) age of 35.1 (14.80) years was selected (42.6% males and 57.4% female). Patients were interviewed prior to dental appointments by a specially trained and calibrated dentist. Responses of the patients were recorded in the structured questionnaire, maintaining their privacy and confidentiality. The data were entered into a Microsoft Excel spreadsheet and analysed using the SPSS statistical package to obtain the prevalence rates of patients' perceptions, which were then cross tabulated with gender, age and other variables. Significant differences were determined using the chi-square test, when appropriate. RESULTS: Of the respondents, 83.5% found it necessary for the dentist to wear gloves, and 65.8% stated the reason was to prevent cross infection from one patient to another. About three-quarters (74.8%) found it necessary for the dentist to wear a mask; when asked about the reason, 52.3% stated prevention of cross infection from dentist to patient. Regarding wearing protective glasses, about three-quarters (73.9%) found it unnecessary for the dentist to do so. The majority (76.8%) stated the method of HIV transmission was by dentists using needles previously used for patients infected with AIDS; 71% knew there is no vaccine against HIV. Only half (49%) reported that hepatitis could be transmitted by blood transfusion. Approximately two-thirds (67.4%) knew there is a vaccine against hepatitis. About 53.5% claimed their knowledge regarding infection transmission was obtained through watching television programmes about cross infection. CONCLUSION: Dental patients in Jordan need to be equipped with adequate knowledge about cross-infection control, thus education reinforcement is imperative.

Attitudes towards COVID-19 Booster Vaccines, Vaccine Preferences, Child Immunization, and Recent Issues in Vaccination among University Students in Jordan.

Although COVID-19 vaccines have been available in Jordan for more than a year, Jordan suffers from a low vaccination rate. The aim of this study was to explore attitudes towards recent issues in vaccination among university students in Jordan. We adopted a cross sectional study design using an online questionnaire distributed in a Jordanian university with a medical school chosen at random. The survey asked about COVID-19 vaccine preferences, factors affecting COVID-19 vaccine preferences, child vaccination, and booster vaccines. A total of 417 students completed the survey. Most respondents (54.7%) preferred the Pfizer vaccine, and 6.2% refused to take any vaccine. Pfizer's efficacy against new strains is a main factor in preferring Pfizer over other vaccines (p < 0.01). Most respondents (71%) believed that vaccination is crucial to prevent COVID-19 surges from new COVID-19 strains, while 44.6% of respondents believed that children should be included in vaccination campaigns, and 70% believed that booster vaccines required more studies to prove their efficacy. Students had mixed attitudes towards many recent issues concerning COVID-19 vaccination. Studying these factors and attitudes in more depth and in different populations can pave the way towards improving vaccination rates worldwide.

Effect of oral diseases on mothers giving birth to preterm infants.

OBJECTIVES: To determine the association between preterm birth (PTB) and maternal oral diseases during pregnancy. SUBJECTS AND METHODS: This prospective study was performed by the neonatal and dental departments at Jordan University Hospital. The study included 100 women who gave birth to preterm singleton infants (born less than 37 complete weeks from last menstrual period) between January and July 2009. The control group included an equal number of women who delivered singleton, full-term infants on the same day or the day after the women in the study. The mothers' demographic data were collected using a questionnaire, and an oral examination was conducted for each participant. Statistical analysis was performed using SPSS for Windows release 16.0 (SPSS Inc., Chicago, Ill., USA). Factors related to PTB were studied in univariate and multivariate logistic regression analyses. RESULTS: Significantly higher DMFT (decayed, missing, filled teeth) index scores, Silness and Loe plaque index scores and Mühlemann tooth mobility index scores were associated with PTB. Mothers who did not have prepregnancy dental checkups had a significantly higher incidence of PTB. Fewer mothers in the PTB group visited dentists during their last pregnancy compared with controls. CONCLUSIONS: Oral health, especially healthy periodontium, is one reliable indicator for predicting a safe pregnancy outcome.

Age of the donor affects the nature of in vitro cultured human dental pulp stem cells.

OBJECTIVES: The dental pulp stem cells (DPSCs) of six donors (three young donors aged < 19 years and three adult donors aged > 25 and < 30 years) were characterized for their stem cell marker expression and differentiation potential to study the effect of donor age on DPSCs in vitro. METHODS: DPSCs were cultured in αMEM supplemented with 20% fetal calf serum (conventional conditions) or on fibronectin-coated flasks with neurobasal medium supplemented with B27, bFGF and EGF (alternative conditions). DPSCs were characterized by immunofluorescence staining to detect the neural crest/mesenchymal stem cells markers P75 and CD146, respectively. The differentiation potential was tested by the induction of DPSCs into osteogenic, adipogenic and glial lineages and then by detecting the corresponding markers osteocalcin, lipidtox and S100ß, respectively. RESULTS: The DPSCs of the young donors expressed CD146 only under the conventional conditions and expressed P75 regardless of the culture conditions. However, the DPSCs of adult donors expressed CD146 only under the alternative conditions and expressed P75 only under conventional conditions. Only the DPSCs of the young donors differentiated into the glial linage. The DPSCs of the adult donors differentiated more efficiently into the adipogenic linage. Osteogenic differentiation was comparable. CONCLUSION: Donor age affects the expression of stem cell markers and differentiation potential of DPSCs. Moreover, the effect of culture conditions on DPSCs is age dependent.

Efficacy of intraligamentary anesthesia in maxillary first molar extraction.

INTRODUCTION: Infiltration anesthesia (IA) is the method to anaesthetize maxillary teeth successfully. In contrast, intraligamentary anesthesia (ILA) has been used as supplementary anesthesia during tooth extraction, particularly when regional block anesthesia has failed. In this study, we compare the efficacy of and patient satisfaction with ILA vs IA when extracting maxillary first molar teeth. METHODS: Forty patients were enrolled in this study and 80 maxillary first molars extracted. All patients served as their own control, with ILA as the experimental side and IA as the control side. The two techniques were compared for efficacy using a visual analog scale (VAS) and patient satisfaction compared using a verbal rating scale (VRS). RESULTS: The mean VAS pain score for extraction using ILA was lower than that for IA (20.30±3.18 and 13.93±1.95 mm, respectively; P<0.001). For injection pain, the mean VAS pain score in the ILA side was higher than the IA side (42.28±4.51 and 31.73±3.1 mm, respectively; P<0.001). VRS results showed a higher number of patients who felt that pain during ILA was greater than expected compared with IA. CONCLUSION: IA appears less painful during injection compared with ILA, and provides sufficient pain relief during extraction. However, ILA can be used when IA fails to achieve the desired pain suppression, as it provides higher extraction-pain relief.

Dentists' knowledge and practice regarding prevention of infective endocarditis.

OBJECTIVES: The objective of this study is to assess the knowledge and practice of dentists from Jordan, regarding prevention of infective endocarditis (IE) in dental practice. MATERIALS AND METHODS: A sample of Jordanian dentists was interviewed regarding their IE knowledge and practice using a validated and pretested survey instrument. RESULTS: Most of the dentists have encountered a patient with IE who needed prophylactic antibiotic (PA) and have prescribed antibiotics to prevent IE. Jordanian dentists' approach to patients in need for PA varied between the National Institute for Health and Clinical Excellence recommendations and the American Heart Association to a lesser degree, but still a relatively high percent (39%) did not know any guidelines to follow although 74% have encountered patients who needed endocarditis prophylaxis. Patients with prosthetic heart valve were ranked on top of medical conditions that required PA (87.4%), and most dentists (94.5%) thought that dental extractions need PA followed by periodontal surgery (88.2%). CONCLUSION: There is a lack of consistency in the knowledge and practice of Jordanian dentists with regard to IE. There is a need to take actions to improve dentist's knowledge regarding this topic.

Current sedation practice among general dental practitioners and dental specialists in Jordan: an example of a developing country.

PURPOSE: The study reported here aimed to identify current sedation practice among general dental practitioners (GDPs) and specialist dental practitioners (SDPs) in Jordan in 2010. METHODS: Questionnaires were sent by email to 1683 GDPs and SDPs who were working in Jordan at the time of the study. The contact details of these dental practitioners were obtained from a Jordan Dental Association list. Details on personal status, use of, and training in, conscious sedation techniques were sought by the questionnaires. RESULTS: A total of 1003 (60%) questionnaires were returned, with 748 (86.9%) GDPs and 113 (13.1%) SDPs responding. Only ten (1.3%) GDPs and 63 (55.8%) SDPs provided information on the different types of treatments related to their specialties undertaken under some form of sedation performed by specialist and/or assistant anesthetists. Approximately 0.075% of the Jordanian population received some form of sedation during the year 2010, with approximately 0.054% having been treated by oral and maxillofacial surgeons. The main reason for the majority of GDPs (55.0%) and many SDPs (40%) not to perform sedation was lack of training in this field. While some SDPs (26.0%) indicated they did not use sedation because of the inadequacy of sedative facilities. CONCLUSION: Within the limitations of the present study, it can be concluded that the provision of conscious sedation services in general and specialist dental practices in Jordan is inconsistent and inadequate. This stresses the great need to train practitioners and dental assistants in Jordan to enable them to safely and effectively perform all forms of sedation.

Age prediction in the adult based on the pulp-to-tooth ratio in lower third molars: a cone-beam CT study / Predicción de edad en el adulto basada en la proporción pulpa-a-diente en terceros molares inferiores: un estudio por TC de haz de cono

Estimation of age-at-death is an integral part of the identification process of individuals in many forensic odontology cases where their identity cannot be determined by visualization or other ways. Dental age estimation in the adult is more challenging as most of the dentition is completely developed by 18 years of age. This study employs a mesio-distal (MD) pulp-to-tooth ratio taken at the neck of lower third molars (LM3) to provide an estimation of age at the time of radiographic imaging based on the well-known fact that pulp volume tends to decrease with advancing age due to continued apposition of secondary dentine throughout adulthood. A total of 155 Cone-beam computed tomography (CBCT) radiographs of LM3s for a random sample of 155 Jordanian Arabs (80 females, 75 males; age range= 18-58 years, mean age= 28.2 years, SD =10.0 years) were used. Both pulp and tooth MD diameters were measured at the neck. MD pulp-to-tooth ratios for LM3s were linearly regressed against age. Statistically significant negative association was found between an individual's age at the time of imaging and the MD pulp-to-tooth ratio taken at the neck. Specifically, the strength of the association is r= -0.361, which means only 13.0 % of the variation in age can be explained by the MD pulp-to-tooth ratio taken at the neck. Therefore, it was concluded that MD pulp-to-tooth ratio taken at the neck of LM3s is not a reliable predictor of chronological age in adults, possibly due to the large variation in the timing of LM3 development.

La estimación de la edad es una parte integral del proceso de identificación de los individuos, en muchos casos en odontología forense donde la identidad no puede ser determinada por visualización u otras formas. La estimación de la edad dental en el adulto es aún más difícil ya que la mayor parte de la dentición se desarrolla completamente a los 18 años de edad. Este estudio emplea una relación mesio-distal (MD) de pulpa a diente tomada a nivel del cuello de los terceros molares inferiores (LM3) para proporcionar una estimación de la edad en el momento de la imagen radiográfica basada en que el volumen de pulpa tiende a disminuir con el avance de la edad debido a la continua posición de la dentina secundaria a lo largo de la edad adulta. Se examinaron un total de 155 radiografías de LM3 en una muestra aleatoria de 155 árabes jordanos (80 mujeres, 75 varones), rango de edad = 18-58 años, edad media = 28,2 años, DE = 10,0 años. Específicamente, la fuerza de la asociación es r=0,361, lo que significa que sólo el 13,0 % de la variación en la edad puede explicarse por la proporción pulpa-a-diente.

New form of administering chlorhexidine for treatment of denture-induced stomatitis.

BACKGROUND: The purpose of this study was to evaluate the release of chlorhexidine as an antifungal drug from doped self-cured poly (methyl methacrylate) (PMMA) acrylic resin and the effect of the drug released on the growth of Candida albicans. METHODS: Release of chlorhexidine was evaluated using liquid chromatography, and the effect of the drug on the growth of C. albicans was investigated microbiologically using a "well" technique on Saboraud culture medium inoculated with a resistant strain of C. albicans. RESULTS: Chlorhexidine leached steadily out of the acrylic resin into distilled water at mouth temperature, and the sustained drug release continued throughout the 28-day test period. The drug released also demonstrated antifungal activity against the resistant strain of C. albicans. CONCLUSION: The findings of this study support the use of chlorhexidine-impregnated self-cured PMMA chair-side resin as a new dosage form for the treatment of denture-induced stomatitis.

The knowledge and attitude about HIV/AIDS among Jordanian dental students: (Clinical versus pre clinical students) at the University of Jordan.

BACKGROUND: The present study aimed to address the suspected deficiency in the level of understanding of HIV/AIDS among clinical and pre clinical dental students at the University of Jordan. In this cross-sectional study, structured questionnaires were distributed to fifth year dental students (n = 121) and to third year dental students (n = 144) in the academic year 2008/2009. FINDINGS: Significantly higher percentage of fifth-year students compared to third-year students felt that the teaching they received on cross-infection precautions and barrier dentistry was adequate (P < 0.001). Majority (84.2%) of fifth-year students were aware that individual carrying anti-HIV antibodies to be an HIV carrier, only 57.7% of third-year students were aware of this fact (P < 0.001). Majority recognized the association between Kaposi sarcoma, oral candidiasis and hairy leukoplakia with HIV/AIDS but knowledge of the association between HIV/AIDS with less frequent lesions was inadequate.Significantly higher proportion of third-year students compared to fifth-year (39.2% vs. 26.3%) thought that HIV patients should be referred to other centers or support groups for treatment (P = 0.04). CONCLUSIONS: The level of knowledge of Jordanian dental students about HIV and AIDS was generally acceptable; there were inadequacies, however, in their understanding regarding some aspects of AIDS epidemic which demands that dental school curriculum needs some improvement.

The mental foramen II: radiographic study of the superior-inferior position, appearance and accessory foramina in Iraqi population / El foramen mental II: estudio radiográfico de la posición superior-inferior, aspecto y forámenes accesorios de una población Iraquí

Accurate information regarding the vertical location and appearance of the mental foramen, and the presence of accessory foramina, can have clinical significance, such as reducing complications that may occur during many oral surgical procedures involving the mental area. Geographic variations were reported in these variables. The aim was to evaluate the above-mentioned variables in an Iraqi sample. Five hundred eighteen panoramic radiographs of a random Iraqi sample (257 males, 261 females, average age= 46.5 years) were evaluated with regard to the above-mentioned variables, as well as the symmetry of the foramen regarding these variables. The area below the apices of mandibular premolars, and the continuous type were the most frequent vertical location and appearance of the mental foramen, respectively. Age advancement was found to be associated with an increase in the frequency of more inferior positioning and continuous appearance. The vertical position and appearance were asymmetrical in 16.2 % and 20.1 % of cases, respectively. Symmetry in the vertical location was statistically significant between sexes (P= 0.035), and young and old ages (P= 0.000). Symmetry in the appearance was found statistically significant (P= 0.025) only between the two age groups. Accessory foramina were recorded in 7.3 % of cases. The most common vertical location and appearance of the mental foramen on panoramic radiographs in this group are below the apices of mandibular premolars, and continuous type, respectively. This is in consistence with the findings of previous studies on other populations. The mental foramen usually has symmetrical vertical location and appearance. Accessory foramina are recorded in a percentage lower than that recently reported in some regional countries.

La información precisa acerca de la localización vertical, apariencia del foramen mental y la presencia de forámenes accesorios, puede tener importancia clínica, como la reducción de las complicaciones que pueden ocurrir durante muchos procedimientos quirúrgicos orales relacionados con el mentón. Las variaciones geográficas fueron reportadas en estas variables. El objetivo fue evaluar las variables anteriormente mencionadas en una muestra iraquí. Fueron evaluadas 518 radiografías panorámicas de una muestra aleatoria de Irak (257 varones, 261 mujeres, edad media = 46,5 años) con respecto a las variables antes mencionadas, así como la simetría del foramen con respecto a estas variables. El área por debajo de los ápices de los premolares mandibulares y el tipo continuo, fueron la localización vertical y apariencia del foramen mental más frecuentes, respectivamente. La edad avanzada se asoció con un aumento en la frecuencia de posicionamiento más inferior y de apariencia continua. La localización vertical y la apariencia fueron asimétricas en 16,2 % y 20,1 % de los casos, respectivamente. La simetría en la localización vertical fue estadísticamente significativa entre sexos (p= 0,035), y entre jóvenes y viejos (P= 0,000). La simetría en apariencia sólo fue estadísticamente significativa (p= 0,025) entre los dos grupos de edad. Se registró presencia de forámenes accesorios en un 7,3 % de los casos. La localización vertical del foramen mental más común en las radiografías panorámicas de este grupo están por debajo de los ápices de los premolares mandibulares, y respecto a la apariencia, el tipo continuo fue el más común. Esto está en coherencia con los resultados de estudios anteriores en otras poblaciones. Los forámenes mentales tienen una localización vertical y apariencia que suelen ser simétricas. Los forámenes accesorios se registran en un porcentaje inferior al informado recientemente en algunos países de la región.

The mental foramen I: radiographic study of the anterior-posterior position and shape in Iraqi population / Foramen mental I: estudio radiográfico de su posición antero-posterior y forma en población iraquí

Accurate information regarding the horizontal location and shape of the mental foramen can have clinical significance, such as reducing complications that may occur during maxillofacial surgical procedures involving the mental area. Geographic variations were reported in these variables. The aim was to study the horizontal position and shape of the mental foramen, as seen on panoramic radiographs of an Iraqi sample, to assess difference in these variables between sexes and age groups, and to assess symmetry of the mental foramen. 518 panoramic radiographs of a random Iraqi sample (257 males, 261 females, average age=46.5 years) were evaluated with regard to the horizontal location, shape and symmetry of the mental foramina. The area between the long axes of the two mandibular premolars, and the round type were the most frequent horizontal location and shape of mental foramen, respectively. Age advancement was found to be associated with an increase in the frequency of more posterior positioning and irregular shape. The horizontal position and shape were asymmetrical in 21.6% and 31.6% of cases, respectively. The Symmetry in horizontal location and shape of mental foramina were found statistically significant between sexes (P=0.041), and between young and old age groups (P=0.001), respectively. The most common horizontal location and shape of the mental foramen on panoramic radiographs in this group are between the two premolars, and the round type, respectively. This is in consistence with the findings of previous studies on other populations. The mental foramina have usually symmetrical horizontal locations and shapes.

Información precisa sobre la ubicación horizontal y forma del foramen mental puede tener importancia clínica en la reducción de complicaciones durante procedimientos quirúrgicos maxilofaciales que involucran el área mental. Fueron reportadas variaciones geográficas en relación a estas variables. El objetivo fue estudiar la posición horizontal y forma del foramen mental, a partir de 518 radiografías panorámicas de una muestra aleatoria en sujetos de Irak (257 varones, 261 mujeres; edad media= 46,5 años), quienes fueron evaluados con respecto a la posición horizontal, forma y la simetría de los forámenes mentales. En individuos de edad avanzada se encontró una asociación con un aumento en la frecuencia de un posicionamiento posterior y con forma irregular. La posición horizontal y forma del foramen fueron asimétricos en 21,6% y 31,6% de los casos, respectivamente. La diferencia hallada en relación a la simetría en posición horizontal y forma de los forámenes mentales fue estadísticamente significativa entre sexos (p=0,041), y entre los grupos de edad jóvenes y mayores (P=0,001), respectivamente. Se encontró con mayor frecuencia la posición horizontal entre los ejes longitudinales de los dos premolares mandibulares, y la forma circular, en relación a la posición antero-posterior y forma del foramen, respectivamente. Estos fueron resultados similares a estudios anteriores sobre otras poblaciones. Los forámenes mentales son simétricos, respecto a su ubicación horizontal y su forma.

The unstimulated salivary flow rate in a jordanian healthy adult population.

BACKGROUND: Early diagnosis of xerostomia is very important for oral health. The purpose of this study was to determine the unstimulated whole salivary flow rates (UWSFR) in a Jordanian Arab population aged 15 years and older. The effect of age, gender, height, weight, body mass index (BMI), smoking, alcohol consumption, and dental conditions, on UWSFR was also investigated. METHODS: The study was conducted on 244 subjects, 110 males and 134 females, with an average age of 33 ± 15.5 years. They were healthy, unmedicated, and with no history of dry mouth. Unstimulated whole saliva was collected during five minutes, and UWSFRs (ml/min) were determined. Data were analyzed by univariate analysis and multivariate regression analysis. RESULTS: The mean UWSFR was 0.46 ± 0.25 ml/min (range: 0.10-1.6 ml/min). Eighteen patients (7.4%) had UWSFR between < 0.20 ml/min. In univariate analysis, UWSFR was significantly affected by age, BMI, number of missing and restored teeth, and DMFT score. Regression analysis revealed that only age and number of missing teeth were of significance in explaining the variability of the UWSFR. CONCLUSIONS: We established basic standard values of UWSFR to be used in the evaluation of Jordanian patients with complaints of xerostomia and to be compared to data reported in other studies. UWSFR 0.1 ml/min could be considered the cut-off value that distinguishes normal from abnormal salivary function in this healthy unmedicated population. KEYWORDS: Whole saliva flow rate; Unstimulated; Jordan.

Prevalence of temporomandibular joint disorders among students of the university of jordan.

BACKGROUND: This study aimed to investigate the prevalence of temporomandibular disorder (TMD) among students of the University of Jordan. METHODS: Information about the symptoms of TMD and the possible risk factors were collected using specifically designed questionnaires. The collected data sets were treated statistically using the SPSS release 14 package. RESULTS: The results of the present investigation showed that pain in or about the ears or cheeks was the most prevalent symptom whereas locking of the temporomandibular joint (TMJ) was the least prevalent. Nearly one-third of the investigated sample (31.4%, 346/1103) had no symptoms of TMD whereas 68.6% (757/1103) had at least one symptom. Students of health science studies had significantly the highest risk in developing TMJ clicking compared to students studying pure science or humanitarian studies. CONCLUSIONS: TMD is of a high prevalence among students of the University of Jordan, particularly among students of health and science studies, which signify the role of stress in the development and/or progression of TMD. The findings of this study are alarming and entailing further investigations to identify risk factors associated with TMD in order to establish measures for prevention and treatment. KEYWORDS: TMD; Clicking; Health sciences; Humanitarian studies.

Uncommon incidental pseudoaneurysm. Diagnostic and management challenges.

OBJECTIVE: To analyze patients with uncommon incidental pseudoaneurysms, secondary to non-catheterization causes, and to discuss the peculiar clinical spectrum, and focus on some aspects of difference from post-catheterization pseudoaneurysms. METHODS: Eleven patients, 8 males and 3 females, were studied retrospectively in Jordan University Hospital, Amman, Jordan, between 2002-2008. Radiological studies performed included duplex sonography (DS), computed tomography (CT), conventional angiography, magnetic resonance imaging (MRI), and magnetic resonance angiography (MRA). RESULTS: Pseudoaneurysms were most commonly encountered in young males (63.6%), especially in the lower limb vessels (36%). Clinical findings were suggestive of pseudoaneurysms in 27% of our cases. Four out of the 8 DS scans showed the neck of pseudoaneurysms, and the to and fro waveform, the strongest indicators for pseudoaneurysms. Both CT with intravenous contrast and angiography failed to establish the diagnosis in one out of 5 cases. The MRI with MRA showed the pseudoaneurysms in 2 patients that underwent the scan. CONCLUSION: Incidental pseudoaneurysms are considered following iatrogenic procedures, penetrating, or blunt traumas with variable delay time. Young healthy males are at increased risks, as opposed to elderly females with calcified vessels in post-catheterization cases. Duplex sonography is less sensitive in incidental than post-catheterization pseudoaneurysms. The CT scan with intravenous contrast has high accuracy in establishing the diagnosis in small, or medium sized pseudoaneurysms. The MRI and MRA are accurate valuable studies and comparable to conventional angiography.

Analysis of clinical records of dental patients attending Jordan University Hospital: Documentation of drug prescriptions and local anesthetic injections.

OBJECTIVES: THE AIM OF THIS STUDY WAS TO ANALYZE CLINICAL RECORDS OF DENTAL PATIENTS ATTENDING THE DENTAL DEPARTMENT AT THE UNIVERSITY OF JORDAN HOSPITAL: a teaching hospital in Jordan. Analysis aimed at determining whether dental specialists properly documented the drug prescriptions and local anesthetic injections given to their patients. METHODS: Dental records of the Dental Department at the Jordan University Hospital were reviewed during the period from April 3rd until April 26th 2007 along with the issued prescriptions during that period. RESULTS: A total of 1000 records were reviewed with a total of 53 prescriptions issued during that period. Thirty records documented the prescription by stating the category of the prescribed drug. Only 13 records stated the generic or the trade names of the prescribed drugs. Of these, 5 records contained the full elements of a prescription. As for local anesthetic injections, the term "LA used" was found in 22 records while the names and quantities of the local anesthetics used were documented in only 13 records.
