    Traumatic dental injuries (TDIs) are frequent events during childhood, and emergency management of these injuries has positive outcomes.

    The aim of this study was to evaluate the knowledge of parents of school-aged children about dental trauma and to identify the effect of demographic variables such as age, gender, and education on their responses.

    300 parents of elementary school children were selected through cluster sampling from July 2012 to January 2013 in Yazd, Iran. A questionnaire was designed to collect the data on parents’ knowledge about emergency management of dental trauma, and their demographic characteristics and previous experiences. Statistical analysis of data was performed by SPSS software version 11 using T-test and ANOVA. P-values less than 0.05 were considered significant.

    296 out of 300 participants returned their questionnaires (mean age 33.8± QUOTE ± 5). The parents’ knowledge about TDI managements was inadequate (average score = 7.03). According to T-test and ANOVA statistical tests, there was no significant relationship between knowledge and age (

    = 0.155), gender of parents (

    = 0.113), gender of children (

    = 0.776), occupation (

    = 0.112), and the information source (

    = 0.160). The relationship between parents’ knowledge and parental educational level was statistically significant (

    = 0.010), and least significant difference (LSD) test showed that knowledge score of parents with Bachelor’s degree or higher educational levels (7.83±4) was significantly more than other parents who were not educated (6.97±4), or had high school diploma (6.70±4).

    Majority of parents had little knowledge about TDI and emergency management of avulsed permanent teeth in children. Therefore, it seems that educational programs are necessary to improve parents’ knowledge.

    Diabetes mellitus is one of the most common endocrine disorders. This disease has devastating effects on many organs and tissues of the body including oral and dental tissues.

    The aim of this study was to evaluate the knowledge and attitude of diabetic patients about dental and oral diseases.

    In this cross-sectional study, 433 diabetic patients who referred to Kerman Diabetes Clinics were included. Data were collected using a questionnaire consisted of three parts of demographic characteristics, knowledge of oral and systemic complications of diabetes mellitus, and patients’ attitude regarding their oral health. Data were analyzed using SPSS version 21 and employing t-test and multiple linear regression analysis. Statistically significant values were considered at

    ≤ 0.05.

    The mean scores for the knowledge of systemic and oral complications were 0.80±0.21 and 0.39±0.23, respectively. The mean total knowledge of diabetic patients was 0.53±0.18, and the mean score for the patients’ attitude was 0.63±0.11. It was revealed that people with a family history of diabetes did not have significantly greater overall knowledge (

    = 0.082). Also, people with longer disease duration (

    = 0.004) and female patients (

    = 0.05) had significantly a better knowledge and attitude in terms of oral health.

    The knowledge and attitude of patients regarding their oral and dental health and diseases were at moderate level, which should be promoted by constant planning and education according to the current needs of society.

    Systemic conditions can affect the salivary glands and oral health. Hypertension induces xerostomia. Because the function of saliva is related to its quality and quantity, therefore, any changes in saliva can lead to diminished quality of patient’s life.

    The aim of this study was to determine the relationship between pH and viscosity of cumulative unstimulated saliva and hypertension in adults with sustained hypertension.

    This cross sectional study took place on patients referred to oral medicine faculty of Shahid Sadoughi University of Medical Science. The patients’ blood pressure was measured and the 135 patients fitting the inclusion criteria participated in the study. Selleck Compound 9 Their unstimulated cumulative saliva was collected by spitting method and pH of the samples was measured by digital pH-meter set. The viscosity of the samples was measured by comparing the amount of saliva displacement in the thistle tube with control fluids at mm/10 seconds. The data was analyzed by SPSS version 20 software and ANOVA tests and Tukey multiple comparison and their nonparametric equivalent (

    ≤ 0.005).

    The results of this study showed that there was a significant relationship between pH and viscosity of unstimulated saliva of normotensive and borderline hypertensive patients (

    <.0001and

    < .005, respectively) and between normotensive and stage I hypertensive patients (

    <.0001,

    <0.000). Therefore, hypertension had a direct and significant relationship with saliva viscosity but a reverse relationship with saliva pH.

    Hypertension can reduce the pH and increase the salivary viscosity in hypertensive patients, which subsequently lead to changes in quality and quantity of secreted saliva and influence the oral health and quality of the patient’s life.

    Mel-CAM (CD

    , MUC

    ) is a 113-kD heterophilic cell-cell adhesion glycoprotein found in normal and tumoral tissues. The biologic functions and role of the Mel-CAM can be employed as a diagnostic marker in pathology.

    The aim of this study was assessing the expression of Mel-CAM in common oral carcinomas like salivary gland mucoepidermoid carcinoma (MEC) and oral squamous cell carcinoma (OSCC) to differentiate the OSCC from high-grade MEC.

    This study was performed on 19 specimens of MEC and 17 specimens of OSCC, which were retrieved from the archive of Department of Pathology of Taleghani Hospital, Tehran, Iran. Immunohistochemical staining was performed by using antibody against CD

    . The data were analyzed using SPSS software through Mann-Whitney, Spearman’s correlation coefficient, and Kruskal-Wallis tests.

    Mel-CAM was expressed in all MEC samples and 10 OSCC cases. The two groups were significantly different regarding the CD

    expression (

    = 0.035). Furthermore, the CD

    expression was found to be significantly correlated with the invasion mode (

    = 0.
