Langerhans cell histiocytosis (LCH) is a rare disease with formation of granulomatous infiltrations consisting of Langerhans cells, histiocytes, lymphocytes and eosinophilic granulocytes. The ethiopathogenesis of the disease has not been fully clarified yet. It can occur as focal or disseminated form - acute or chronic. Oral manifestations may be the first signs. This article reports a case of a 3 year old boy with LCH suffering from severe dental mobility and foul breathe. Radiographically, the lesions appeared as well-defined radiolucent defects in maxilla and mandible. The microscopic findings consisted of sheet like arrangements of histiocytes with a mixture of eosinophils and other inflammatory cells. Biochemical tests were within normal limits.

Background and Aims: Using the conservative adhesive resin restoration (CAR) in uncooperative children lead to numerous problems because of being time consuming. The purpose of this study was to compare the microleakage of conservative adhesive resin restoration under separate curing and co-curing.

Materials and Methods: In this experimental study, 120 intact premolar teeth were collected and 120 vertical grooves were prepared on them. Then the teeth were divided into four groups: group 1, separated curing of bonding agent, flowable composite and sealant group 2, co-curing of all materials for 60 seconds group 3,
co-curing of all materials for 40 seconds and group 4, co-curing of all materials for 20 seconds. Then the specimens were thermocycled and immersed in basic fuchsin solution. The teeth were sectioned horizontally and dye penetration was evaluated with stereomicroscope. Date were analyzed using one-way ANOVA and Scheffe test.

Results: Mean value of dye penetration in groups 1, 2, 3, and 4 was 1.53±0.6, 2.06±0.6, 2.5±0.7 and 3.53±0.6, respectively. There was a statistically significant difference between group 1 and the other groups (P=0.0001).

Conclusion: Considering the problems caused by microleakage in conservative resin adhesive restorations, co-curing method should not be used. In the case of using co-curing method, 60 second curing time is suggested for sufficient polymerization.

  Background and Aims: Dental environment is a stressful place for children. In many cases, parents transmit their anxiety to their children in the first dental visit. Mothers as the closest person to the children may have important influence on their children’s behavior in dentistry. The purpose of this study was to evaluate the effectiveness of an educational pamphlet for mothers on children’s behavior in the first dental visit.

  Materials and Methods: This study was conducted on 238 mothers who had 3-7 years old children undergoing dental treatment for the first time. The participants were divided into interventional and control group randomly. Behavior of children was assessed by questionnaire according to 4 point scale of Frankle. The questionnaire contained 5 parts: separation of child from the mother, entering the dental room, opening the mouth, communicating with dentist, getting the prize. Data were analyzed using Chi-square test.

  Results: The educational pamphlet was effective on the separation of child from the mother, the cooperation of children in interventional group was better than the control group (P=0.006). In interventional group 96.2% of and in the control group 90.8% of children had good and very good behavior but the difference was not significant (P=0.11).

  Conclusion: Although the educational pamphlet was effective on the separation of child from mother. No significant difference in behavior of 3-7 year-old children between interventional and control group was found.

Background and Aims: Despite significant decline in dental caries in recent decades, the disease remains a public health problem especially in developing countries. In recent years combined application of laser and fluoride has been introduced as a new caries-preventive measure. The purpose of the present study was to review the literature on the preventive effect of combined application of laser and fluoride on the dental caries. Materials and Methods: PubMed, Google Scholar and EMBASE databases were searched for articles published from 1990 to November 30, 2013. Various combinations of the following keywords were used: Dental caries, Laser, Fluoride, Fluoride therapy, Prevention and Enamel. The inclusion criteria included all levels of available evidence. Articles published only in english language were evaluated, and unpublished data were not sought. Results: Several studies evaluating the effect of laser alone or combined with topical fluoride to prevent dental enamel demineralization were found. Studies assessing the combined effect were more frequently done on permanent teeth and just a few studies were done on primary teeth. In total, most of the studies confirmed that combined application of laser and topical fluoride has a remarkable effect in prevention of enamel demineralization compared to application of each of them alone. Conclusion: Laser irradiation combined with topical fluoride application seems to provide the best prevention effect on the dental caries initiation and progression in enamel of permanent teeth. However, more experimental and clinical studies are necessary to be done on the primary teeth in this area.

Background and Aims: One of the most effective methods in reducing the prevalence of caries is oral health education. The aim of this study was to evaluate of two educational interventions regarding prevention of early childhood caries on self-reported practice of parents of 2-5-year-old children receiving dental treatment under general anesthesia.

Materials and Methods: In this interventional study, the effects of two different educational interventions
(pamphlet and pamphlet along with reminder) on self-reported practice of parents of 2-5-years-old children receiving dental treatment under general anesthesia was assessed. Thirty seven couples of children and mothers in two groups were randomly selected. Before and three months after interventions, a standard questionnaire regarding self-reported practice of mothers on prevention of early childhood caries was completed by respondents. Moreover, oral examination including Simplified oral hygiene index (S-OHI), dmft, and white spot lesions were rerecorded at the beginning and three months after interventions. At this time in one of the groups reminder phone calls were made every month. Finally, the answers were scored and data were statistically analyzed to be compared in pre- and post-test.

Results: Comparing each of the groups before and after interventions showed that in both groups there were significant differences in mothers’ perception of perceived ability to make child brush his teeth twice a day (P=0.001), and child’s tooth brushing frequency more than once a day (P=0.03). S-OHI had no significant difference after the intervention between two groups. But each group had a significant decrease three months after intervention (P=0.003). Also the mean number of white spots showed a significant decrease before and after intervention in each groups. Regarding mothers’ self-reported practice no significant difference was observed between two groups (P>0.05).

Conclusion: Using pamphlets along with or without reminder as educational measures had similar enhancing effects on the mothers’ self-reported practice on oral health of children within three months.

Background and Aims: Selecting the appropriate education evaluation method and the effects of this choice according to different fields of medical sciences, is one of the current priorities of medical education. Therefore, the aim of this study was to design a checklist for evaluating the practical skills of dental students and to get compared with the global ranking method.
Materials and Methods: A checklist was developed for the assessment of clinical skills of the practical pediatric course according to an action research method. 32 students were evaluated by the checklist method and 32 students were evaluated by the conventional global rating method (sampling was based on available sample).  Faculty staff and students’ satisfaction regarding the two methods were reported by a 6-scaled measure and statistically analyzed by Wilcoxon Signed Ranks test. The students' scores by the two methods were subjected to paired t test for comparison.
Results: The students were more satisfied with the checklist method (P=0.003). The faculty staff considered a greater ability of the checklist method to differentiate between the students (P=0.03). However, in terms of ease of use and suitability, most faculty staff preferred the traditional method (P=0.02). In other cases, there were no significant differences in the views of students and faculty staff towards the two methods.
Conclusion: In the present study, both Checklist and global rating methods were valuable for evaluation, although due to the greater satisfaction of students and faculty staff with the developed checklist method, the possibility of identifying the weak points leading to decreased scores and better assessment of capabilities, this checklist can be used for evaluation instead.
