Background: Many bacteria are involved in dental plaque formation and caries. Streptococcus mutans is one of the most important bacteria involved in this case. One of the ways to control plaque is the use of mouthwash on the side of toothbrushes and toothbrushes. Although chlorhexidine is the most effective mouthwash against oral microorganisms, the side effects of long-term use suggest the need for an alternative. The purpose of this study was to compare the antibacterial effect of nanosilver and chlorhexidine mouthwash on Streptococcus mutans in pediatric ward of Dental School of Islamic Azad University of Tehran and Laboratory of Veterinary School of Tehran University in 1397-1398. Materials and methods: This experimental study was performed in vitro on Streptococcus mutans. Experiments were performed on two groups of case (nanosilver mouthwash) and control (chlorhexidine mouthwash) in three parts. Antimicrobial potency was measured by Disk diffusion assay by measuring inhibitory zone diameter. Then both micro and macro dilution methods were used to measure MIC (Minimum bacterial growth Inhibitor Concentration) and finally for measure MBC (Minimum Bactericidal Concentration) using Blood agar dilution method. Results : Statistical analysis showed that the nanosilver mouthwash has no inhibitory zone and MBC. Also its MIC was higher than chlorhexine and this difference was statistically significant (P <0.001). Conclusion: According to the results of the in vitro study of nanosilver mouthwash compared to chlorhexidine, it has minor bacteriostatic properties and no bactericidal effect. It is recommended to repeat this study by changing the mouthwash formulation in terms of particle concentration and diameter.
背景:许多细菌与牙菌斑的形成和龋齿有关。变形链球菌是本病例中最重要的细菌之一。控制牙菌斑的方法之一是在牙刷和牙刷的旁边使用漱口水。虽然氯己定是对抗口腔微生物最有效的漱口水,但长期使用的副作用表明需要一种替代品。本研究的目的是比较纳米银漱口水和氯己定漱口水在1397-1398年在德黑兰伊斯兰阿扎德大学牙科学院儿科病房和德黑兰大学兽医学院实验室对变形链球菌的抗菌效果。材料与方法:本实验采用体外诱变链球菌进行。实验分为两组,分别为纳米银漱口水和对照氯己定漱口水。采用圆盘扩散法测定抑菌带直径,测定抑菌效力。然后分别用宏观稀释法和微观稀释法测定最小抑菌浓度MIC,最后用血琼脂稀释法测定最小杀菌浓度MBC。结果:统计分析表明纳米银漱口水无抑菌带和MBC。其MIC也高于氯己嗪,差异有统计学意义(P <0.001)。结论:纳米银漱口水的体外研究结果表明,纳米银漱口水与氯己定相比抑菌作用较小,无杀菌作用。建议通过改变漱口水配方的颗粒浓度和直径来重复这项研究。

We conducted a study on parent’s knowledge, attitude and practice on oral health in Saveh City, in primary schools. Materials and methods: In this study, a standard questionnaire was used to evaluate mother’s knowledge, attitude and practice of on oral health. Mothers of 735 students in 16 primary schools (randomly selected) in Saveh were participated. Mother's knowledge, attitude and practice level were measured by 11, 9 and 5 questions with 36, 36 and 20 scores respectively. Chi-Square tests and ANOVA were used to analysis data. Results: The results showed that mothers had a mean scores of 19.29 (± 0.214), 23.52(±0.142) and 10.69 (69 0.119), in knowledge, attitude and practice respectively. There was a significant and direct relationship between knowledge and attitude, and also between knowledge and behavior levels (P<0.001). About 80% of the mothers brushed once or twice a day, and 90% of mothers used fluoride toothpaste. Daily use of dental floss was very low. About two-thirds of mothers only went to dental offices if they had problems. There was a significant and direct relationship between mother's education with their knowledge, attitude and performance (P<0.001). There was no relationship between mother's age and gender of students with their knowledge, attitude and performance levels. Conclusion: It is necessary to improve information of mothers, especially who are less educated to get better oral health behavior by information brochures, holding training classes and free dental examination services.

Corresponding Author: zahrahosseini69@ gmail.com Background: Epidemiologic knowledge can signify the importance of prevention, diagnosis and treatment planning. This study aimed to assess the frequency of dental trauma, type of injury, type of treatment performed and time of admission of dental trauma patients presenting to the School of Dentistry of Tehran University of Medical Sciences during 2011-2018. Materials and methods: In this retrospective, descriptive study, pediatric dentistry postgraduate students evaluated the charts of patients admitted to the dental clinic of School of Dentistry, Tehran University of Medical Sciences during 2011-2018 due to dental trauma. Age and sex of patients, type of traumatized tooth, cause of injury, type of injury, time interval between the trauma and visit and type of treatment performed were all recorded. Descriptive data were reported as frequency and percentage. Different types of dental injuries were compared using SPSS version 22. Results: Of 165 injured patients, 63.03% were males and 43.03% were between 8-9 years of age. The prevalence of trauma to the maxilla and mandible was 90.02% and 9.96%, respectively. The maxillary central incisors had the highest frequency of trauma (72.09%). Slips and falls were the most common causes of trauma (73.93%) while sport injuries were the least common (6.06%). In terms of type of trauma to the teeth, intrusion was the most common and crown and root fracture were the least common in primary dentition while tooth crown fracture was the most common and extrusion was the least common in permanent teeth. Of injured patients, 3.03% sought treatment in less than 4 hours and 6.66% between 6-12 months after injury. Treatments included simple tooth restoration (27.6%), splinting (11.6%), pulpectomy/root canal treatment (12%), pulp-capping (1.2%) and replantation (2%). Conclusion: Traumatic injuries are common in children and adolescents. The current results showed that age and gender were among the predisposing factors to dental injuries. Maxillary central incisors were the most commonly traumatized teeth. Tooth crown fracture was the most common injury in permanent teeth while intrusion was the most common inj ury in primary teeth. Slips and falls were the most common causes of dental trauma. Composite restoration was the most common and pulpectomy was the least common treatment. Patients mainly presented within 4 to 24 hours after injury. Those presenting 6-12 months later had the lowest frequency.

e73ebrahimzadeh@gmail.com Background: DMFT index is the most common caries detecting index worldwide. The aim of present study was to determine DMFT as well as the prevalence of highest caries rate or Significant Caries Index (SiC), among 15 years of age female students in the city of Rasht, Iran. Materials and methods: In this descriptive cross-sectional study, 228 female students were selected using stratified multi-stage sampling method. Demographic status was assessed by questionnaire. Clinical examinations were conducted by a trained senior dental student. DMFT index was firstly determined by WHO criteria. At the next stage, SiC index was extracted by calculating DMFT among one third of study population who had the highest rate of DMFT. Analyzed by SPSS 21. Spearman correlation, Kruskal Wallis و Chi-square T-test, Data were used for data analysis. Results: The mean DMFT was 3.29±2.7, and SiC index was 6.19±0.76. Spearman correlation determined that there was a positive direct correlation between DMFT and the number of children within the family (P<0.0001). A negative correlation was observed between DMFT and daily tooth brushing(P<0.0001). Conclusion: The mean DMFT index among 15 years-old females was similar to mean national scores. The number of siblings and tooth brushing were correlated with DMFT score in the study population.
e73ebrahimzadeh@gmail.com背景:DMFT指数是世界范围内最常见的龋病检测指标。本研究的目的是确定伊朗拉什特市15岁女学生的DMFT以及最高龋率或显著龋指数(SiC)的患病率。材料与方法:本研究采用分层多阶段抽样方法,选取228名女大学生进行描述性横断面研究。采用问卷调查的方式评估人口统计状况。临床检查由一名训练有素的高级牙科学生进行。DMFT指数首先由WHO标准确定。在下一阶段,通过计算DMFT发生率最高的三分之一的研究人群中的DMFT来提取SiC指数。采用SPSS 21进行分析。采用Spearman相关、Kruskal Wallis χ 2 t检验、Data进行数据分析。结果:DMFT平均值为3.29±2.7,SiC指数为6.19±0.76。Spearman相关确定DMFT与家庭子女数呈正相关(P<0.0001)。DMFT与每日刷牙呈负相关(P<0.0001)。结论:15岁女性DMFT指数与全国平均水平相近。在研究人群中,兄弟姐妹的数量和刷牙情况与DMFT评分相关。
