Objectives: The purpose was to determine the antibacterial properties of propolis and to evaluate its use as an antibacterial mouthwash with minimal complications. Materials and Methods: In this experimental laboratory study, an alcoholic propolis extract was prepared. The minimum inhibitory concentration (MIC) was calculated for four bacterial species including Staphylococcus aureus (S. aureus), Streptococcus mutans (S. mutans), Lactobacillus acidophilus (L. acidophilus), and Enterococcus faecalis (E. faecalis) using agar dilution. According to the MIC, a propolis antibacterial mouthwash was produced and compared to water, chlorhexidine (CHX), and Listerine using laboratory rats for clinical examination. Salivary specimens of rats were collected at 12 hours, 1 week, and 2 weeks after using the mouthwash and examined by the real-time polymerase chain reaction (RT-PCR). Data were analyzed using one-way analysis of variance (ANOVA) and repeated measures ANOVA (α=0.05). Results: The results of agar dilution by the number of colony-forming units (CFU) showed the lowest MIC for S. aureus and the highest for L. acidophilus. The results of the RT-PCR indicated that water alone had no effect on the level of oral bacteria. Propolis mouthwash showed a significant difference with CHX and Listerine (P<0.05) in terms of the number of S. mutans, E. faecalis, and L. acidophilus colonies, while CHX and Listerine were less efficient. There was no significant difference between CHX and propolis (P=0.110) regarding S. aureus colonies, but Listerine had a lower efficacy than either (P<0.05). Conclusions: According to the results, propolis mouthwash was more efficient against the studied oral bacteria compared to CHX and Listerine.

Aim:Evidence-based dentistry (EBD) is an approach to oral health that requires the application and examination of relevant scientific data related to the patient's oral health and his priorities. The aim of this study was to assess knowledge, attitude, and practice of dental students of Isfahan about EBD.Materials and Methods:In this descriptive study, 168 dental students in 3 final years of their education who engaged in clinical practice by consensus sampling were recruited. For data collection, a validated questionnaire was used. The questionnaire was consisted of demographic questions and some questions about four issues: Knowledge of self-assess (KSA), evidence-based practice, actual knowledge and attitude about EBD. Data were analyzed with t-test, one-way ANOVA, Chi-square, and linear regression with SPSS 16.Results:One hundred and thirty-six students from 168 students were filled the questionnaire. The mean of KSA was 13 ± 4.3, mean of usage of useful references in EBD was 16.9 ± 7.6. One-third of students were studied their last article in last 6 months before. The mean of actual knowledge and attitude was 7.4 ± 2.3 and 24 ± 3.8, respectively. The relation between 4 main issues was significant (P < 0.05).Conclusion:By considering overall interest and positive attitude toward learning EBD in dental students, it is highly recommended that practical educational courses about EBD be planned by dental faculties.

INTRODUCTION:The current study aims to study people's access to oral and dental health-care services and their satisfaction with the services provided to them.MATERIALS AND METHODS:A descriptive study with multi-stage sampling was conducted on 1360 people aged 16–64 years residing in Isfahan city, Iran. The required data were collected by a questionnaire which comprised of three main parts: demographic characteristics, patients’ access to oral and dental health-care services and its barriers and participants’ satisfaction with access to services. Data were analyzed by SPSS statistical software.RESULTS:The results showed 40% of participants reported an average level for oral health, and 82% of them did not have any problems regarding access to dental care facilities. The main causes of their dissatisfaction were high cost of services (60%) and insufficient health insurance coverage (40%). About 73% reported that they had to spend 30 min or less to access to a dental health-care facility. In addition, 50% of participants were satisfied with the provided services. The main reported reasons for referring to dentists were oral and dental problems (69%) and regular check-ups (15%). There was no significant relationship between participants’ gender, education level, insurance coverage, and access to dental health-care centers (P > 0.05).CONCLUSION:Most participants were satisfied with access to dental healthcare, but they were dissatisfied with the costs and inadequate insurance coverage. About half of the participants were satisfied with the services provided to them, and the highest level of satisfaction was reported for easy access to health-care centers.

Introduction: Injury to both the primary and permanent dentitions is one of the most common dental problems. The prognosis of dental trauma depends on the basic measures taken immediately after trauma. This study was designed to assess the level of knowledge, the attitude of kindergarten coaches about primary teeth trauma in Khorramabad city. Materials & Methods: In this Cross-sectional study, 100 kindergarten coaches in Khorramabad participated in this study in 2019-2020. A valid and reliable confirmed questionnaire was used for data collection. Data were analyzed with Pearson correlation coefficients and independent t-test (p value < 0.05). Results: In this study, the mean score of coaches’ attitude was 68.5 and the mean score of knowledge was 34.9. In the present study, the factors of gender, age, level of education had no significant relationship with their knowledge score (p value > 0.05) and attitude, but between work experience with knowledge scores (p value = 0.02) and attitude (p value = 0.004) and so between the level of knowledge (p value = 0.004) and attitude (p value = 0.008) and passing the dental emergency training course, a direct relationship was observed. In this study, there was a significant relationship 64% of the coaches experienced dental trauma and their mean score of knowledge (p value = 0.04) and attitude (p value = 0.001) was significantly higher than other coaches. Conclusion: The assessed level of dental knowledge of the coaches participating in this study was poor, whereas their attitude about primary tooth trauma was good. The great suggestion is to hold educational programs in this regard to increase the level of knowledge of kindergarten coaches in the field of dental trauma.
