Un-cooperative children with massive dental need are usually suitable candidates for outpatient dental procedures under general anesthesia. Discharge from recovery without complications is an ideal goal achieved by the use of short acting anesthetic agents. This study was designed to evaluate the duration of recovery as well as potential complications in propofol infusion anesthesia. In this descriptive cross sectional study, forty five healthy patients, aged 5-10 years were selected from the pool referred to the Department of Pediatric Dentistry at Isfahan Dental School for treatment. Initial evaluation and allocation for treatment under General Anesthesia was performed based on proof of lack of cooperation. induction of anesthesia with thiopental was carried out along with maintenance of anesthesia with infusion of propofol under mechanical ventilation. The duration of recoverywas recorded as well as any complications being made over the course of recovery. Data were then analyzed using basic statistics. Duration of recovery was 43.5 ± 22.12. In total 51.1 % of the patients reported no complications, however the remaining 48.9 % of the patients there was at least one complaint at the recovery time. The most important complaint was irritability with an incidence of 44.4 %. Maintenance of anesthesia with propofol infusion can reduce duration of recovery and therefore speed up the discharge time for patients (children) who received their dental treatments under GA.

Dental plaque contains more than 500 bacterial species. Geographic location, race, gender and diet play a role in diversity of plaque microorganisms. The objective of this study was to evaluate the aerobic bacteria in dental plaque and its relationship with dental caries of 3-5 year old children in Mashhad. In this analytical-cross sectional study, one hundred 3-5 year old children who referred to pediatric dental clinic of Mashhad Dental School and had no systemic problems, were selected. After oral examination, a sample of dental plaque was taken and the aerobic bacteria were identified. Data were analyzed with Chi- Square, T-Test, Mann Whitney and Fisher exact tests. The frequent microorganisms isolate in this study include: Streptococcus viridanse, Staphylococci, Candidia, gram positive bacilli and other Cocci. There is a significant relationship between the Streptococcus viridanse, Staphylococci, gram positive Bacilli and dmfs, also the level of Streptococcus viridanse increased with age. The high level of Streptococcus viridanse and gram positive bacilli in dental plaque, have significant relationship with dental caries.

conservative procedures using dentin-bonding agents are one of the important aspects of pediatric dentistry. The Purpose was to comparatively evaluate the microleakage of total etching single bottle system(Single Bond) to self-etching adhesive system(Prompt-L-Pop) in primary dentition. Thirty extracted sound primary molars were selected. One class V cavity preparation was prepared in flat buccal/lingual surfaces of all teeth. Then the specimens were divided into two groups. In Group1, Solution from two bottles of Prompt - L - Pop were mixed and applied. In Group 2after etching with 35% phosphoric acid, Single Bond was applied. All the cavities were filled with composite (Z-100). The teeth were thermocycled between 5 and 55 degrees C with a dwell time of 30 seconds and then stored in normal saline. All teeth were sealed apically and coated within 1mm of the margin with two layers of nail varnish. After Basic fuschin dye immersion for 24 hours, buccolingual cuts parallel to the long axis of the teeth were made. Degree of Microleakage was evaluated and scored under stereomicroscope. The results were analyzed by mann-Withney test. Score 0.1 was noted in Prompt - L - Pop group, and scores 1,2,3 in Single Bond group. The finding illustrates significant difference in microleakage between two types of adhesive systems, since less microleakage was found in Prompt - L -Pop group. It was conclded that concerning the single step application and lower microleakage, the self-etching adhesive is better for bonding in primary dentition.

Oral health in school is an important part of general health program. School years are an important period that oral health habits (behaviors) for whole life and personal attitude develop in this period. School can be a good environment for promotion of oral health. This study evaluates the oral health practice of health workers in Tabriz primary schools. This cross-sectional and descriptive study evaluated all Tabriz school that had health workers. A questionnaire was sent to the schools that had health workers. After gathering, levels of the practice of the health workers that had answered this questionnaire were evaluated. SPSS software and independent t-test and paired- sample t-test were used for analyzing the results. Fifty eight out of 64 (90.65%) school health workers (SHW) were female and 52 of them (81.3%) had bachelor's and the others had master's degree. Mean of acquired practice score was 7.14 out of 10. Almost 84% of health workers informed the parents for their kid's oral and dental status or problems. Practice of school health workers had a significant relation to their experiences and experiences as health worker. SHWs who were employed in past decades all were female; therefore they had higher mean age. SHWs with two years education had longer experiences and better practice in school although this difference was not significant.

Dental absence causes functional and esthetic outcomes in the involved patients so that the diagnosis and decrease of these complexities are of main concerns. Furthermore, maxillary lateral incisors absence develops the esthetic problems than other teeth. The aim of this study was to evaluate the prevalence of absence of maxillary permanent lateral incisors in 12-15 years-old students of guidance schools in Qazvin during 2008-2009. In this descriptive-cross-sectional study, 1512 students of guidance schools in Qazvin city were selected via simple cluster sampling and underwent initial examinations was done in classrooms under daylight. Students, doubtful for maxillary lateral incisors absence, were referred for a detailed analysis to Qazvin Dental School, then they were examined by radiographic assessments and further analyses were performed on them. The data were reported by frequency and percentage indices. The congenitally absence of maxillary lateral incisors was observed in 16 students (1.058%) of the total populations: 7 cases (43.8%) occurred in the right side, 2 cases (12.5%) in the left side and 7 cases (43.8%) were bilateral. 11 samples (68.8%) had permanent dentition and 5 students (31.3%) were in mixed dentition. No case of supernumerary teeth and scar of lip, pre maxilla and palate. The prevalence of maxillary lateral incisors in the 12-15 years-old students of Qazvin city compares with the other reported values in the studied populations.

Different behavior management techniques have been used in children to perform dental treatments. With the increased role of parents in decision making regarding their children, their acceptance of different behavior management techniques received more attention. The present study assessed the acceptance of routine behavior management techniques by parents attending the department of Pediatric Dentistry, Dental School of Shahid Beheshti University of Medical Sciences in 2008-2009.Methods and materials:In this descriptive, non randomized study, 63 parents (49 mothers, 14 fathers) with no history of dental treatments for their children were included. Parents received information about tell-showdo (TSD), voice control (VC), premedication, physical restraint, hand over mouth (HOM) and modeling techniques by using images in clinical environment. They were instructed on advantages and disadvantages of each technique. Parents agreement of each technique was determined by using 10-cm visual analogue scale (VAS) in which the first and end points showed complete agreement and disagreement respectively. Data were subjected to one-way analysis of variance (ANOVA) and student t tests.

The TSD technique received the highest acceptance with the mean value of 9.63. The modeling, premedication, VC, physical restraint and HOM techniques ranked the next orders with the mean values of 9.24, 8.21, 5.86, 2.92 and 1.73 respectively. Fathers accepted aggressive techniques like physical restraint (P<0.02) and HOM (P<0.02) more than mothers, with no significant difference regarding other studied techniques. Furthermore no significant differences were found regarding parents’ education level and number of their children with the acceptance of different behavior management techniques. Only a significant relationship was found between parents’ age and their acceptance of HOM technique.

Under this study limitation, parents attending dental school of Shahid Beheshti University of Medical Sciences accepted most of behavior management techniques and tended to cooperate with the dentist although none of these techniques received their complete acceptance. The mostly accepted technique was TSD and the results were similar to that of previous studies.

Acandroplasia is a genetical disorder which involves development of bone and cartilages. This is known as the main cause of dwarfism. This article aims at colaborating clinical oral sings associated with the disease.Case Report: A 6 years old male individual who was earlier diagnsed with acondro plasia was referred to the dental school where a full clinical examination proved the conditton. Radiographic evaluation showed that all permanent to teeth as being similar in developmental stage but delayed compare to a normal case. This was however surprisingly not the case in permenet molars.

all teeth buds were beyond their developmental ago but their peramet molar s were different.

Drinking tea is looked upon as a cultural Iranian custom. Although using tea evokes the image of black tea, depending on the processing style, a variety of teas are derived from the plant tea, each with numerous treatment qualities and different effects on health. For centuries China and other countries have been using various teas to treat diseases. For this reason, this fact has served the purpose of research conducted by a large number of scientists. Tea contains not only a considerable quantity of fluoride but has also proved positive in the treatment of oral diseases. This essay is the result of almost fifty scientific sources about the plant tea, its varieties, the effects of each variety on the oral and dental health and diseases, factors affecting the fluoride content and the rate of fluoride released during infusion of tea. Several studies indicate that different types of tea have different medicinal effects. Over the years in dentistry field, the only notable aspect of tea was its fluoride content but recent studies show some other medical effects of different types of tea in oral cavity. Knowing the fact that the tea of each country and geographical area can have their unique qualities in addition to the processing style and other geographic properties affecting outcome, there is a virgin ground for research in different dentistry fields in Iran.
