Introduction:Regarding the anatomic variety in the anterior mandible it is necessary to obtain adequate information about the vital structures in this area to protect them in dental surgeries and preventing injuries that might occur afterwards. The aim of this study is to describe anatomic characteristics of mental foramen and anterior loop on CBCT images.
Materials and Methods: On CBCT images of 326 hemimandibles, opening angle of mental foramen, vertical distance from mental foramen to the mandibular inferior border, location of mental foramen in relation to nearby teeth and the length of the anterior loop were measured.
Results: Anterior loop was present in 52.1% of hemimandibles. The mean exit angle of mental foramen was 42.72±10.82 degrees. The highest frequency of the location of mental foreman with respect to the adjacent teeth was between the first and second premolar and the lowest frequency was between canine and the first premolar as well as between the second premolar and the first molar. The mean distance from mental foreman to the mandibular lower border was 15±5.85 millimeters. The mean length of the anterior loop was estimated to be 3.92±1.17 millimeters.
Conclusion: Regarding variations in anatomic characteristics of mental foramen and anterior loop, precise examinations of these vital structures are necessary to protect them during surgical procedures of mandible.

Introduction: Human Immunodeficiency Virus (HIV) infection is known to be a cause of health and socioeconomic problems in affected patients. In 1981, approximately 25 million people were killed by HIV in the world. In 2015, World Health Organization (WHO) estimated that approximately 36 million people are infected with HIV throughout the world. The aim of this study was to assess the knowledge and attitudes concerning HIV/AIDS amongst Iranian dental students in 2019, and to evaluate the effect of school years and gender on the aforementioned items.
Materials and Methods: A total of 200 questionnaires were distributed among Iranian dental students (Response rate = 93.5%)(n=187). Unpaired t-test and One-way ANOVA were used to evaluate their mean level of knowledge and attitude.
Results: In total, 188 students filled out the questionnaires; of them, 97.8% were aware that dentists can be infected by HIV-positive patients and 3.3% did not know that oral manifestations are helpful in diagnosis of HIV-positive patients. Approximately, all the students (98.9%) believed that HIV transmission could occur via needle stick injury during the dental practice. About 40% (n=72) of the dental students believed that they were able to treat HIV/AIDS patients safely.
Conclusion: The knowledge and attitude towards HIV/ AIDS of females and sixth year students were more significant than others. Knowledge and attitude amongst Iranian dental students towards HIV/AIDS were relatively good, but it should be reinforced.

Introduction: Hepatitis B is a major public health problem globally affecting two billion people. Assessing knowledge and increasing awareness about HBV are part of the main actions against hepatitis B. This research was intended to assess the knowledge and awareness regarding hepatitis B among dentists.
Materials and Methods: This cross-sectional, descriptive, questionnaire-based study was conducted among 105 general dentists in Qazvin using a structured questionnaire containing two sections. In the first section, recorded data was about age, gender, and the number of years that the participant was graduated. The second section contained 22 questions of which 18 questions assessed the knowledge of dentists about HBV. Their knowledge was scored from 1 to 18 and then categorized as good, moderate, and poor. Data obtained from research questionnaires were analyzed by SPSS software version 21 using Mann-Whitney and Kruskal-Wallis tests. Values of p < 0.05 were considered statistically significant.
Results: Effect of gender, age, and number of years that the participants were graduated, were not significant on the awareness of participants. (P=0.928 and P=0.822, P=0.938, respectively) The mean of their knowledge was 6.37±2.44. 77.1% (54) of participants had poor knowledge and 18.6% (13) of participants had moderate knowledge. Only 4.3% (3) of participants had good knowledge about HBV
Conclusion:Overall knowledge of dentists about HBV was poor in the current study.It is essential to improve the knowledge of dentists about HBV and Hepatitis B.
Introduction
Hepatitis B is a major public health problem globally. Hepatitis B is caused by the hepatitis B virus (HBV) and is a potentially life-threatening liver infection leading to liver cirrhosis and liver cancer.(1-3)
About two billion people have been found to be infected with HBV around the world, of which 350 million patients are facing chronic liver diseases and 600,000 are dying because of hepatitis B, annually. This fact leads hepatitis B to be the 10th cause of death worldwide.(3-5)
Transmission of Hepatitis B is through infected blood and body fluids; which can occur through direct contact with blood and saliva or through indirect contact (contaminated instruments and environments). This makes medical, surgical, and dental procedures to be a common route for HBV transmission.(4-8) Dentists among the other co-medical workers are more vulnerable to hepatitis B for frequently getting exposed to blood and saliva in daily practice. (1,4)
A recent study in Laos demonstrated that 86% of students in the healthcare professions had poor knowledge about Hepatitis B.(9) World Health Assembly addresses that assessing knowledge and increasing awareness is part of the main actions and cornerstones in the prevention of hepatitis B along with effective vaccination.(1-2,5-6) Therefore, this research was intended to assess the knowledge and awareness regarding hepatitis B among dentists.

Introduction: Percutaneous injuries are one of the important health problems of health care workers, because such injuries are the main risk factors in transmission of blood-borne diseases. Needlestick injury (NSI) is the entrance of a bloody contaminated sharp instrument (needles, surgical blade, ....) into the body during or after treatment procedures of a patient. The aim of this study was to evaluate frequency, knowledge and practice about needle stick injuries among Iranian dentists attending retraining programs of Iranian general dentists community in 1394.
Materials and Methods: In this cross-sectional study, self-administered questionnaires were distributed among 150 dentists. Data were analyzed by Spearman, Mann-whitney U and kruskal wallis.
Results: 84.4 % of dentists had experienced NSI at least once. only 15.4% of dentists had never had NSI. Needle was the most common cause of recent needle stick injury (20%) among dentists. The mean score of knowledge was 6.35 (45.35% of total number) and the mean score of practice was 6.12 (68% of total number). There was no correlation between knowledge and practice (P< 0.848). There was significant negative correlation between practice and age(p<0.003), and also between practice and years of work (p<0.003).
Conclusion: The results show high frequency of NSI among dentists. NSI occurrence can be reduced significantly by using standard precautions. Continuous education and retraining programs play an important role in updating knowledge of dentists.
