Thalassemia major is one of the most prevalence congenital diseases in the world. This disease is wide spread in Iran and created some problems for health-care system. The aim of this study was to determine of situation oral health among thalassemic patients of Qazvin city in 2013.
In this descriptive - analytic study, thalassemic patients were selected with census method (n=60). Data were collected with examination, and interview. Questionnaire was include demographic, clinical and paraclinical information. Patients were examined and followed up by a dentist. DMFT index was determined on the basis of the examinations. Validity and reliability of the questionnaire was conducted. Data were analyzed by descriptive and analytic statistic tests with SPSS, version 16.
The majority of patients were female (%61.2) and had a history of blood transfusion (%67.3). The most of patients (%83.7) had no history of dental visit and most of them (%77.6) had no tooth brushing. The majority of patients had varying degrees of tooth decay. DMFT index was %57. The frequency of brushing and age had significantly effects on tooth decay (P Thalassemic patients have more problems in comparison other people. Diagnostic and therapeutic procedures have increased their survival. . Thus health indicators include oral and dental hygiene should improve in these patients specially.

The purpose of the present study was to investigate the effect of storytelling on anxiety, pain and anger of dentistry among 4-8 years old children.
The children referred to dentist, daycare center, creativity center and play center of Neka and Sari were included in the study. Thirty-nine children, who referred to the researcher, were selected via convenience sampling method and randomly divided into three groups (experimental, placebo and control group). They completed Venham picture test, Wong-baker faces pain scale and Children's Inventory of Anger. The experimental group received 8 session of group therapy. The control groups received no intervention, but placebo group received 8 sessions of vulgar storytelling. The data analyzed by SPSS-16 and significant level was chosen less than 0.05.
The results of MANCOVA and bonferroni post- test and follow-up showed that there were significant reductions on the frequency of dental anxiety, pain and anger in the experimental group compared with, placebo and control groups.
The findings suggest that storytelling can be used as a well-established psychotherapy for children to reduce symptoms of dental anxiety, pain and anger.

Dental caries in deciduous teeth could progressively involve the pulp. What matters in pulpectomy is wiping out microorganisms and their products. The aim of this study is to compare antimicrobial effect of thymus vulgaris essential oil with that of chlorhexidine.
Forty teeth with clinical analysis of not more resorption than one third of the root went under pulpectomy and were infected with Enterococcus faecalis. Teeth were devided into four groups and the canals were washed with normal saline, chlorhexidine %0.2, thymus vulgaris essential oil %2, and thymus vulgaris essential oil %5. Eventually the microbial culturing was done, and antimicrobial effect of the aforementioned disinfectants was investigated. Also, four teeth were considered as the control group. Kolmogorov–Smirnov test, and Kruskal-Wallis test were used for statistical analysis, while Mann-Whitney U-test was utilized to compare the two samples means. The level of significance was less than 0.05.
Results illustrated that thymus vulgaris essential oil %2 had the most antimicrobial effect, whereas thymus vulgaris essential oil %5 was proved a more effective disinfectant in comparison with chlorhexidine %0.2, although this difference was not significant. Nevertheless, thymus vulgaris essential oil %2 was significantly more effective than chlorhexidine %0.2.
Annihilating the bacteria is the major cause of performing pulpectomy, and many chemical irrigants are put to use to achieve this goal. Meanwhile, the urge to substitute medicinal plants for chemical irrigants is expanding, and thymus vulgaris essential oil %2 can replace the conventional disinfectants in dentistry.

Brushing teeth at least twice a day is the most important factor in reducing the risk of dental decay. However, there are barriers in conducting this behavior. Perceived barriers are most important dimensions in anticipating protective behavior for health. Identifying barriers of oral health can help researchers in designing better and more effective intervention t promote this behavior. Aim of study reported here was identifying perceived barriers of mothers in brushing teeth of their 3- 6 years old children.
This qualitative study was conducted in Kamyaran in 2014. Purposeful sampling with highest diversity was conducted. 40 mothers of 3-6 years old children were interviews using deep semi structure interview technique. Data were analyzed using thematic content analysis method.
Barriers were categorized in two main groups including “perceived barriers related to mother and family members “and “barriers related to child”. Most important barrier was the attitudinal factors of mothers.
Discussion and Identifying barriers for practicing healthy behaviors and planning to tackle these barriers are important prerequisite of changing behavior and success of health education programs. Findings of this study emphasize on the role of attitude of mothers and family members on oral health of children. Hence, it can contribute to better oral health promotion for children of 3-6 years old.

Dental schools try to train skilled and competent dentist to promote oral health services. This study assesses the clinical skills of pediatric dentistry among dental students in the Faculty of Dentistry, Tehran University of Medical Sciences (TUMS), Iran.
This descriptive cross-sectional study by census sampling evaluates all of the 55 senior dental students. The data were obtained by a valid and reliable questionnaire. The students’ judgments about their level of dental practical skills were assessed using a 5-scaled lickert device and scoring from 1 to 5 respectively from very low, low, moderate, high and very high. The data were reported by mean of descriptive statistical method for each educational department. The effect of related factors like gender, age, and scantling to enter the dental school, was analyzed by a mean of regression coefficient.
All senior students participated in the study (response rate was 100%). Eight items of practical skills out of seventeen were assessed as high or very high by more than 60% of students. Management of traumatized teeth was presented by more than 70% as low or very low.
Regarding the results, the studied dental students showed an acceptable level of dental practical skills, however; curriculum was not successfully achieved its own ideal objectives, then, some modifications are necessary to be performed considering the skills with the lowest scores.

Title: Oral health awareness and information sources in mothers of preschoolers in a non-affluent area in Tehran.
Dental caries of the under 6-year-olds may involve them with mental, physical and social problems. We aimed to study oral health awareness and information sources in mothers of preschoolers in a non-affluent area in Tehran.
Participants were composed of 100 mothers referring to 6 urban health houses of the region 11 in Tehran. Mothers filled a questionnaire on demographics, knowledge (7 questions) and sources of information (7 sources) regarding children’s oral health. Linear regression served for statistical analysis.
The mean for mothers’ awareness score was 5.1 out of 7. The lowest number of mothers’ correctly answering was for “bacterial transition from mother to child” and highest was for the “role of fluoride toothpaste”. Their most common sources were TV and dentist, respectively. Mothers’ knowledge was higher in those with higher educational level and those whose children were second or third child in the family.
The results revealed that despite using diverse information sources, mothers’ awareness was low. Involving them in oral health promotion programs may improve children’s oral health in non-affluent areas.

Maintaining the integrity of the dental arch in the primary and mixed dentition is important for establishing occlusion and function in the permanent dentition. The primary reasons for premature loss of teeth in children are either dental caries or trauma. Proximity of caries or trauma to pulp tissue may lead to pulpitis or even pulp necrosis.. This review article presents the pulp therapy techniques commonly used in pediatric dentistry, their indications and the common therapeutic agents.
Method &Material: A search through PubMed, Google, Scopus and Medline during 1984-2013, a total of 42 original research papers with key words such as pulp therapy, primary teeth, and immature permanent teeth and pediatric was performed. Furthermore, references books were used.
Results & It is a treatment objective to maintain the vitality of the pulp of a tooth affected by caries, traumatic injury, or other causes. Whenever possible, dental treatment should attempt to maintain pulp vitality, particularly in immature permanent teeth. Pulp vitality leads to development of a favorable crown-root ratio, apical closure and formation of secondary dentin.
