The purpose of this survey was the determine of effectiveness of preventive precisures. 320 twelve years school student have chosen randomly. After determination of DMFT All of them divided to 4 groups. First group as control and the other groups were as oral hygiene education 6-fluoride therapy and sealant therapy group in a period of two years.Results of this study showed that fluoride therapy was more effective than the other procisures than oral hygiene instructions.

Over 20 years, several analytical approaches have been designed to predict caries in children.Caries Risk Assessment is a recently developed technique concern to caries prediction.This procedure involves three stages as follows:1- Determination and assessment of the dental caries risk factors.2- Examination and evaluation of each individual child to be specifically diagnosed the level of 3- caries risk e.g. high, moderate and low risk.3- Recommendation of preventive programs according to risk assessment.Because children vary widely in their ability to develop cavities, a well-organized program holds great promise for promoting dental heath for pre-school children of varying caries risk. This article considered a series of principals that dentist can use in case planning, management and prevention programs according to risk assessment.

Background and Aim: Diagnosis of occlusal caries in early stages is more difficult than other types, and  needs practical proficiency and accuracy as well as application of advanced and modern equipments. The aim of this study was to evaluate the variations among dentists in diagnosis of occlusal caries.

Materials and Methods: In this descriptive cross-sectional study, 6 permanent first molar teeth of 8-10 years old children with occlusal caries of 1, 2 and 3 degrees were selected (Espelid method). Color photographs and bitewing radiographs of teeth were displayed on computer monitor and 157 general dentists were asked to determine the existence and depth of caries. Data were analyzed using SPSS software and chi-square test. P<0.05 was considered as the level of significance.

Results: 94% of dentists did not diagnose any lesion in grade I caries.3.8% reported enamel caries (correct diagnosis) and 1.9% reported dentin caries. In grade II caries, 15.7% of dentists could not diagnose any caries, 60.7% recognized the caries at the level of enamel (correct diagnosis), and 22.31% reported the dentin level, and 1.3% reported pulp exposures.7% of dentists could not diagnose any caries in grade III, while 27.2% recognized lesions at enamel and 58.9% at dentin level (correct diagnosis), 6.1% of dentists reported pulp exposures and 0.3% did not respond. Female dentists showed significantly higher correct diagnosis compared to males (p=0.013).

Conclusion: Based on the results of this study, despite considerable variations among general dentists in diagnosis of occlusal caries, the total accuracy was acceptable.

  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.
