The inherent tendency of blood to clot plays a central role in the formation of clots. Anticoagulant agents should be considered essential tools in the management and treatment of patients with coagulation problems. The purpose of this study is to investigate the level of knowledge of dentists regarding anticoagulant drugs and the necessary measures for the treatment of bleeding during dental procedures.

This article reports a cross-sectional analytical study conducted at the Faculty of Dentistry among general dentists at Qom University of Medical Sciences in 1401. The Chi-square and Fisher tests were used to analyze the collected data, which were evaluated using SPSS version 26 software.

Among 121 general dentists with an average age of 30.56 ± 6.89 years and an average work experience of 4.46 ± 5.80 years after graduation, 69 were male and 52 were female. A significant percentage of responses to each question on the questionnaire indicated a lack of knowledge about anticoagulant and antiplatelet drugs. There was no significant relationship between gender, age, or work experience of dentists and most questions in the questionnaire (p > 0.81).

The gender of dentists is not an effective factor in their level of knowledge. Only in the cases of discontinuation of clopidogrel and the postponement of dental procedures due to the use of antiplatelet drugs was there a relationship with the age of general dentists. Additionally, there is a significant relationship between knowledge of the drug prasugrel and the discontinuation of clopidogrel in relation to the work history of general dentists. This lack of connection between these factors demonstrates a need to improve the level of knowledge and awareness among general dentists.

Saliva has a key role in protecting the oral environment and functions such as chewing, swallowing, lack of saliva can cause many problems and suffering for patients and affect people's quality of life. Therefore, the purpose of this study was to investigate the level of awareness of dentists in Yazd City regarding the causes and symptoms and how to treat dry mouth in 2022-2023.

In this cross-sectional descriptive study, 125 dentists of Yazd City were selected by convenience sampling method. A valid and reliable questionnaire was designed. The data were analyzed using t-test and ANOVA statistical tests and SPSS V.16.

The average of age, work experience and knowledge score of the examined dentists were 33.46±7.27, 6.79±6.57 and 15.24±2.90, respectively. There was no statistically significant relationship between knowledge score and gender and work experience and participate in retraining with P = 0.323, P = 0.120 and P = 0.167, respectively. But there was a statistically significant relationship between the knowledge score and age and university of study with P = 0.030 and P = 0.034. People with older age and educated in type 1 university had more knowledge about dry mouth.

The results showed that the dentists of Yazd City had average knowledge about the causes, symptoms and how to treat xerostomia. And it is necessary to cooperate in holding refresher courses in this field.

 Trauma to the teeth is a prevalent problem in children that can lead to depression, psychosomatic issues, social problem, dysphasia and esthetic cancerns for them. Dentists play a crucial role in reducing the side effects of dental trauma so that their knowledge about the causes, prevention and treatment of such truma is of paramount important. Consequently, this study aimed to assess the knowledge and attitude of general dentists’ in Isfahan regarding the management of dental trauma.

 The present study was a descriptive-analytical and cross-sectional study that used a questionnaire consisting of demographic information and general dentists' knowledge about the management and treatment of dental trauma (22 questions) and their attitudes towards the subject (11 questions). The questionnaire was completed by 125 general dentists in Isfahan city who were randomly selected in 2019. The data were analyzed using statistical tests including t-test, Pearson's correlation coefficient, and Spearman's correlation coefficient (p value < 0.05).

 The mean score of general dentists’ knowledge was 13.65 ± 2.71 and the mean score of attitude was 39.01 ± 5.98. Women had higher knowledge about dental trauma than men (P value = 0.002). There was also a negative correlation between age (p value = 0.001) and job experience (p value = 0.026) regarding dental trauma knowledge.

 General dentists’ knowledge, who worked in Isfahan, regarding the treatments of TDI in 2019 was at a moderate level. It is suggested that with holding dental trauma retraining courses about how to manage and urgent treat this traumas, thus being more hopeful to rescue these teeth by increasing the awareness of dentists.

 Tennis elbow disease is one of the most common diseases that cause pain in the elbow joint, the prevalence of which is 1-2% before the age of 40, and it increases 4 times in men and 2 times in women in people over 40 years old. Dentists are a group that are more susceptible to this disease due to frequent physical activities, therefore the purpose of the present study was to determine and investigate the level of knowledge, attitude and performance (KAP) of dentists in Shiraz regarding tennis elbow disease.

The present cross-sectional descriptive study was conducted in 2018. The statistical population included 51 dentists with a clinical experience of at least three years in Shiraz. Participants without direct clinical activity and people with related underlying diseases were excluded from the study. The data collecting instrument was a questionnaire and the final questionnaire was divided into five sections; Personal information, medical information, knowledge survey, attitude survey and performance survey were designed. The collected data were analyzed using analysis of variance, correlation coefficient and multivariate regression tests.

In the studied population, 9.8% of people exhibited symptoms which indicate dtennis elbow disease. On average, the examined dentists were diagnosed with tennis elbow disease 0.13 times in during the previous year. The average score of the ad in the community was 34.9 points out of 100, the average attitude score was 73.1 and the average performance score was 64.1. According to statistical tests, the scores obtained from these three factors were significantly related (p≥0.05).

Despite the acceptable level of knowledge, attitude and performance, the results indicated that there was a significant relationship between age, work history and exposure to joint diseases and disability resulting from tennis elbow disease with the score of knowledge, attitude and performance, which was common to stay away from the learning environment with age. It is suggested to raise the level of knowledge, attitude and performance by health policy makers by passing academic units and holding formal trainings in these areas.

Local anesthesia is a routine part of all dental procedures that can cause complications. One of the most important side effects of intraoral anesthesia is ocular disorders. The aim of this study was to investigate the knowledge and proper management of dentists in Yazd City regarding ocular complications following local anesthesia injection.

In this cross-sectional descriptive study, 193 dentists working in Yazd City were included in the study based on census sampling and they completed a questionnaire, which was consisted of two parts: demographic information and questions referring the knowledge and practice; data were analyzed using SPSS 16 software and ANOVA and T-test and Pearson correlation coefficient.

Mean knowledge score of the participantswas 1.21 ± 0. 6 with a variation range of 0 to 2. The mean awareness score of women was higher than of men, and a statistically significant difference was observed (P-value≤0.05). There was no significant relationship between awareness score and level of education, work experience and age (P-value≥0.05). Only 13.1% of general dentists and 25% of specialists had experienced ocular complications after intraoral anesthesia injection.

Dentists of Yazd City had an average knowledge about ocular complications following local anesthesia injection and due to the great importance of prevention and management of ocular complications following local anesthetic injection, it seems necessary to hold retraining courses on this topic and how to manage it.

Dentists are at risk of musculoskeletal disorders due to their job characteristics. The purpose of this study was to compare the posture and musculoskeletal disorders of dentists with high and low work experience.

This analytical cross-sectional study research was conducted on 76 dentists in Urmia city. Based on work experience, the samples were divided into two groups: less experienced (less than 15 years) and experienced (15 years and more). The variables of forward head, kyphosis, round shoulder, and musculoskeletal disorders were compared in two groups. Forward head and round shoulder variables were evaluated by photography, kyphosis variable by flexible ruler, and musculoskeletal disorders were evaluated by Nordic questionnaire. Data analysis was done using descriptive statistics and analytical statistics (Kolmogorov-Smirnov test, Leven test, independent t-test and Yeoman-Whitney test).

The independent t-test results showed that the angle of forward head, round shoulder, and kyphosis was higher in the high work-experience group than that of the low work-experience group (P=0.001). In comparing the prevalence of neck disorders, the results were significant such that the experienced group had more neck disorders (P=0.002). However, in examining the difference in the amount of disorders in other parts of the body, the difference between the two groups was not statistically significant (P>0.05).

Experienced dentists had a higher degree of forward head, round shoulder and kyphosis positions. Although, there are musculoskeletal disorders in both groups of dentists with low and high level of experience, neck disorders were more common in high-experienced dentists than that of low-experienced ones.

dentists often have to adopt awkward, asymmetric, static postures and tilt their heads forward while working. If this situation continues for a long time every day, it leads to excessive pressure on the involved muscles and joints and causes symptoms such as pain and discomfort, especially in the neck, shoulders, back, and waist. Considering the importance of prevention, and early treatment of musculoskeletal disorders among dentists, this research investigates the effect of three types of chairs used in dentistry on the risk of musculoskeletal disorders and the comfort perceived by dentists using each chair.

This is a descriptive cross-sectional study conveyed in Tehran, the capital city of Iran. The present study includes a survey of a group of 70 male dentists. In this study, three types of chairs were compared. To evaluate body comfort, Corlette, and Bishop’s local discomfort questionnaire was used. The RULA method was used to determine the risk of upper limb musculoskeletal disorders and to assess each dentist's body condition.

The highest level of comfort was reported in the saddle model chair (the difference in the average intensity of discomfort before and after the work shift in the whole body = 12.39), the third type chair (13.04), and the second type chair (18/76). The dentists' posture evaluation results showed that the final score of RULA in three types of chairs varies from a minimum of 3 to a maximum of 7.

According to the results of the study, the average intensity of discomfort in the whole body after using the saddle chair compared to the state before using it has significantly decreased compared to the other two types of chairs, which implies the positive effect of using the saddle chair in reducing musculoskeletal discomfort. The results of posture evaluation indicate that the use of the saddle chair, compared to the other two chairs, improves the working conditions and facilitates the work.

Drug compounds, including acetaminophen, enter the environment through urban and industrial wastewater. The presence of these substances in very small amounts causes adverse effects on health. The goal of this research is to investigate of acetaminophen removal from aqueous solution by batch proxy electrochemical reactor with using zinc-copper electrode and hydrogen peroxide.

This study is a laboratory experimental research. Water sample containing acetaminophen was prepared and removal efficiency in different conditions of variables pH (4-8), c reaction time (30-90 min), concentration of acetaminophen (50-200 mg/L), current density (3-9 mA/cm2), and concentration of hydrogen peroxide (0.5-1.5 mg/L) were studied. Acetaminophen was determined by high performance liquid chromatography at 360. Ethical considerations were observed at all stages of the study.

In electrochemical reactor, the removal rate of 50 mg/L acetaminophen was obtained in the optimal conditions of 2 cm distance between electrodes, 9 mA/cm2 electric current density, 30 minutes electrolysis time, and pH equal to 4, 63%. In proxy electrochemical reactor, the amount of acetaminophen removal at a concentration of 1.5 mg/L hydrogen peroxide, 9 mA/cm2 electric current density, 30 minutes time reaction, an optimal pH equal to 4, and 50 mg/L acetaminophen concentration was obtained 100%.

Based on these results, the peroxy electrochemical method, as a promising and environmentally friendly advanced oxidation technology, is effective in removing acetaminophen from aqueous solutions and the process implementation conditions are more cost-effective compared to electrochemical method.

The 2019 coronavirus pandemic is a major threat to global public health due to unprecedented individual and social fear and anxiety and it puts significant stress on health-related quality of life and challenges health care professionals, including dentists, with increasing patient burdens, unprecedented disruptions in normal life and The high risk of being exposed to the disease has put them in stressful situations and therefore they are more exposed to stressful situations that can affect their quality of life. Therefore, this study was conducted with the aim of investigating the level of perceived stress and the quality of life of the students and professors of Ardabil Dental School in the face of the outbreak of the 2019 coronavirus disease in 2021 and the relationship between these two variables with the demographic characteristics of the participants.

To measure the level of perceived stress, Cohen's Perceived Stress Questionnaire was used, and to measure the quality of life, the World Health Organization Quality of Life Standard Questionnaire-Abbreviated (WHOQOL-BREF) was used. The statistical population in this study is all dental professors and dental students of the Faculty of Dentistry of Ardabil University of Medical Sciences. A significance level of less than 0.05 was considered.

From the statistical population of this study, a total of 227 people including 33 professors and 194 students participated in the study. There was no significant relationship between demographic variables and perceived stress variables and quality of life. Perceived stress and quality of life were higher for professors than for students during the pandemic. There was a direct relationship between perceived stress variables and quality of life in both groups. The level of perceived stress in both groups was lower than the optimal level and the quality of life in both groups was higher than the optimal level.

Students and professors of Ardabil Faculty of Dentistry experienced moderate stress during the Covid-19 epidemic and had a good quality of life. By comparing between the two groups of participants, professors had more perceived stress.

Proper knowledge of prescribing correct radiography techniques, especially among general dentists, is important for the accurate diagnosis of dental problems and not receiving additional doses of radiation in patients. Therefore, the aim of this study was to evaluate the knowledge of general dentists about the accurate prescription of radiography in Rafsanjan City 2021.

In this descriptive cross-sectional study, 100 questionnaires were completed by general dentists in Rafsanjan City to measure the awareness of radiographic methods in 9 different areas of dentistry, and then the knowledge of dentists in these 9 different areas based on age, gender and work experience was compared using independent sample t-test and ANOVA statistical tests (α=0/05).

In this study 53 (53%) of the dentists were male and 47 (47%) were female. The highest rate of correct answer and score was related to knowledge about radiography in children (90%), panoramic (83%) and bite wing (75%) and the lowest rate was related to periodontal questions (40%). Overall, 12% had poor knowledge, 42% had moderate knowledge and 46% had good knowledge. The overall score of knowledge in male dentists (67%) was significantly higher than in female dentists (60%). With increasing work experience, the level of knowledge about the correct prescription of radiographic techniques decreased significantly (p=0.039).

Although the knowledge of dentists in Rafsanjan City was evaluated well in the case of the correct prescription of radiography in most areas, it is still necessary to train in some areas in retraining courses to improve the knowledge of dentists.

The aim of present study was to design a systematic framework to estimate needed dental manpower in Iran based on treatment need index.

Initially, dt, mt, and DT, MT indices were extracted from the data of the last national survey in 2012 for all age groups, assuming a linear trend for dental caries in time intervals. Subsequently, medians for each age group were calculated and used. In next phase, according to data of 194 patients in Tehran School of Dentistry and another dental clinic, the detailed need for dental treatments based on dental caries and periodontal status indices were identified, and then classified. The total time needed for dental treatments were determined via a questionnaire completed by dental assistants of 120 dentists. Accordingly, a mathematical model suggested to calculate the number of dentists needed.

It was assumed that all people have enough affordability for dental utilization, and dentist visits, simultaneously. Dental manpower needed to deliver dental services to all age groups, considering dentist’s ability through one year was calculated.

The method of determining dental manpower needed for Iran based on treatment needs, is applicable for maximum estimation of dentists.

 One of the problems and challenges posed in the dentistry field is to file a lawsuit against dentist that causes discontent ، wasting time and cost and energy for both of them.   This study can be useful for students and dentists because it will enable them to identify cases that lead to the lawsuits and treatment and contact with patients adhere to the principles of professional ethics. purpose of this study was to investigate the relationship between adhere to the principles of professional ethics with lawsuits in Isfahan city between 2010 to 2020.

 In this Cross-Sectional study, 706 files of lawsuits in Isfahan medical records archives and deputy of treatment during 2010-2020 were evaluated and the required information was extracted. The data were analyzed by descriptive statistics test.

A rising trend was observed in the rate of lawsuits. The most cause of lawsuits was related to not having the knowledge, skill and experience, consultation and referral, overbilling, disruptive behavior in the workplace. Frequency of male dentists and general dentists were higher.

 Dental complaints had a rising trend, and the most commonly reported cases related to not having the knowledge, skill and experience, consultation and referral.

Patients, oral health care staff anddentists are exposed to infections and infectious microorganisms during dental imaging. The aim of this study was to evaluate the knowledge and practice of general dentists in Yazd City about infection control during the preparation of intraoral radiographs.

This analytical cross-sectional study, examined the knowledge and practice of 81 active dentists in Yazd City who were selected based on convenience sampling method through a questionnaire. To analyze the data, SPSS 16 ,and Pearson's correlation coefficient as well as One-way ANOVA were used.

The mean age of the participants was 36.45 ± 9.66 and their mean work experience was 10.03±8.28 years. The mean score of knowledge about infection control during intraoral radiographs was more than 50% and it was evaluated as moderate. There was no statistically significant difference between the mean score of dentists' knowledge in terms of gender (P=0.623), age (P=0.849), work experience (P=0.824) and the year of their graduation (P=0.860), but there was a statistically significant difference between the mean score of dentists' knowledge according to their university of study (P=0.015), so that Yazd School of Dentistry graduates had significantly less knowledge than graduates of other faculties.

Considering the importance of infection control in dental radiology and the mean score of dentists' knowledge in the present study, which was moderate, therefore, the need to improve dentists' awareness in this field is emphasized

The lack of information on the knowledge and attitude of dentists towards herpes simplex virus is one of the concerns of the community.

A cross-sectional study was conducted on 400 dentists using continuous referral sampling technique. The questionnaire used to collect data included three sections: there were some questions on individual characteristics, 12 questions on dentists’ knowledge about Herpes simplex infection, and 12 questions on dentists’ attitudes towards this infection. In the section on knowledge, each question received a score of 1. The score range of each attitude question was 0-3. Data were analyzed running chi-squared regression analysis in SPSS, version 11.

Of 400 dentists evaluated, 48.25% were female and 51.75% were male, with a mean age of 30 years.Knowledge was not very good in any of the samples, it was 3.5% good, low in 3.1%, and very low in 96.3%. As for the attitude towards herpes simplex infection, 30.3% had positive attitude, 58.2% had a relatively positive attitude, and 11.5% had a negative attitude. According to the results, there was a significant relationship between the lower age, education, university, and the province of activity (p < 0/05). Furthermore, female gender, age above 30, year of education prior to 2011, and graduates of Azad and Shahed University revealed positive awareness about herpes simplex infection (p < 0/05).

The knowledge and attitudes of dentists studied were lower than the expected levels. Thus, it is necessary to design proper educational programs to improve dentists’ knowledge and attitudes on Herpes simplex infection.
