Background and Aims: Child’ s oral health is believed to be related with maternal dental fear and anxiety. The purpose of the present study was to evaluate the relationship between the demographic status and maternal dental fear and anxiety and its effect on child’ s dental caries. Materials and Methods: This descriptive and analytical study conducted among 374 mothers which had attended to pediatric department of Tehran University of Medical Sciences for their child’ s dental treatments in 2019 were evaluated in the present study. In addition to dental fear survey (DFS) and modified dental anxiety survey (MDAS) questionnaires, demographic information, age, marital status, family income, and educational level of the mother was recorded. Dental visit frequency and previous negative experience were also recorded. DMFT/DMFT (decayed, missed, filled teeth) of the children was recorded according to WHO criteria. To assess the relationship between the variables, Pearson correlation and multiple linear regression were used using SPSS25 software. Results: The mean age of the mothers was 35. 66± 15. 75. There was no relationship between maternal dental fear and anxiety and children’ s dental caries status (P=0. 738). There was no relationship between the mothers’ age and dental fear, and anxiety (P=0. 943). Previous negative experience and education were related to the dental fear and anxiety (P=0. 02). Conclusion: DMFT of the children was not correlated with the maternal dental fear and anxiety. Higher education which was related with less dental fear and anxiety. Previous negative experience is one of the major factors influencing the maternal dental fear and anxiety.

Background and Aim: Major b thalassemia is a hereditary hematologic disease with severe clinical symptoms such as certain organic, skeletal and periodontal difficulties and increase of dental caries rate. The aim of this study was to determine the dental caries rate of Thalassemic children and to compare it with the control groups.Materials & Methods: Sixty b thalassemia and healthy children in three groups, 1-5 years group for DMFT study, 5-12 years for DMFT and DMFT study and after 12 age years for DMFT study were randomly selected. Means of DMFT and DMFT and plaque control indices (the brushing and flossing application) were studied in both groups and between three age groups. Comparisons of results were made using ANOV A and 1.Results: Mean of carious (d, D=4, 5.67) and extracted (m, M=0.22, 0.55) teeth were more in thalassemic patients and mean of filled teeth (f, F=O.45,0.82)were more in control groups. Control group brushed their teeth more frequently and the difference between case and control groups was significant (P<0.05), but there was no significant differences between control and case groups in using dental floss. To summarize, caries rate in both primary and permanent dentition was significantly higher in thalassemic patients comparing to control group (P<0.05).Conclusion: Caries rate is high in both primary and permanent dentition in thalassemic patients. However, there are many contributing factors in the rate of caries in thalassemic children but this study determined lack of adequate dental care as a major factor.

Background and Aim: Considering the importance of oral health in children, it is important to find factors affecting it. Eating habits, body mass index (BMI), and educational level and socioeconomic status of the parents have been suggested as factors affecting oral health. Two important indices for evaluation of general and oral health of children are the BMI and DMFT/DMFT, respectively. The purpose of this study was to assess the relationship between these two indices in children aged 6-12 years. Materials and Methods: In this descriptive analytical study, 300 children aged 6-12 years were selected among those referred to the Dental Branch of Tehran Islamic Azad University of Medical Science in 2019-2020 by simple random sampling. The BMI and DMFT/DMFT were calculated, and the relationship between them and the effect of influential factors on dental caries score were evaluated. Data were analyzed by the linear regression model at a confidence interval of 95% and 0. 05 level of statistical significance. Results: The study sample consisted of 168 girls and 132 boys. The mean DMFT was 4. 66±, 3. 39 and the mean DMFT was 1. 44±, 1. 57 Only 11. 34% of the children were underweight and 12. 66% were obese,while, 60. 67% had a normal weight. Oral health and nutritional behaviors of children showed that 71. 3% of them brushed their teeth at least once a day and only 22% used dental floss. A correlation was found between BMI and the rate of caries in permanent teeth (P=0. 046). Conclusion: No statistically significant association was observed between DMFT/DMFT and BMI of children aged 6-12 years.

Introduction: Two important indices for evaluation of children’s health include BMI and DMFT/DMFT. This study was designed to assess the relationship between these two indices among 7-11year-old children in Yazd.Methods: The sampling technique used in the present study was a cluster random sampling (A total of 400 pupils aged 7-11).In this cross-sectional study BMI and DMFT/DMFT were measured and the relationship between these two indices was evaluated. The effect of such factors as snacks, parent’s education level and frequency of tooth brushing on dental caries score was evaluated. Data were analyzed via McNemar test.Results: Mean of DMFT/DMFT was 5.09±1.95. Eighteen percent of children were at risk of overweight or were overweight. Children at risk of overweight and overweight children had a higher frequency of DMFT/DMFT³5) P<0.001. Consumption of snacks and frequency of toothbrushing had a significant effect on this Index.Conclusion: This study showed a positive relationship between BMI and dental caries score, so that children with higher BMI had a higher DMFT/DMFT. In Further research, this relationship should be investigated by longitudinal studies.

Background: The aim of this study was to determine relationship between the groundwater fluoride (F) concentration and villages elevation with dental caries in children living in the Borazjan villages (in Dashtestan area) of the Bushehr Province.Methods: 13 villages in Dashtestan with only a groundwater source and essentially the same socio-economic living standards conditions were surveyed. All of the children in each village in the ages 6–11 were sampled for a total of 2287 in all villages. F levels in the village drinking water measured by the SPADNS method.Results: F drinking water concentration ranged from 0.99 to 2.50 mg/L, while the number of decayed permanent (Dt) teeth per child ranged between 0.14 and 1.08 and the number of decayed deciduous (dt) teeth ranged between 0.17 and 1.18. Over this narrow concentration range there appeared to be no significant association between the F level in the drinking water and Dt and dt. Also it was appeared villages elevation had no any significant effect on dental carries levels.Conclusion: F drinking water levels higher than 1 mg/L in this area had no any effect in the prevention of dental caries.

Background & Aims: The DMFT index in primary teeth and DMFT in permanent teeth includes drawn (missing) and filled (filling) teeth due to decay and the percentage of children free of caries (caries free) are two important indicators of health in a community. The aim of this study was to measure the wellbeing of DMFT and DMFT indices in Urmia Orphanages.Materials & Methods: This research was a descriptive-analytical study with 93 patients including 23 females and 70 males. They were from orphanages of Urmia with 6-18 years old that were selected by census method, and their teeth were examined with simple tools.The results, along with other information such as age, sex, number of brushing and medical data were recorded. The DMFT and DMFT indices were based on the method recommended by WHO and the results were analyzed using t-test and k square.Results: The mean DMFT was 2.55 and DMFT was 2.5, respectively and the permanent and deciduous tooth was equal. There was no significant correlation between age and sex and DMFT. However, there was significant correlation between age and sex and DMFT. The frequency of brushing and DMFT and DMFT meaningful connections was reported.Conclusion: As a result, the reported decay was higher than WHO criteria for the year 2010 (DMFT≤1).The highest mean in both DMFT, DMFT was related to caries (d, D), respectively. It is revealed that the residents of orphanages need more treatment.

Background and Aim: Oral and dental health and collecting data on the prevalence of dental caries are among the most important aspects of individual health. Thus, it is necessary to determine community’s oral health status. Various epidemiological studies are required at different levels to assess the efficacy of preventive, oral and dental health control programs in a society. Thus, the aims of this study was survey of water fluoride and status of DMFT and DMFT in elementary and medium school students in Kamiran Town.Material and Methods: This was a descriptive cross-sectional study. Data were collected through interview and dental clinical examination using disposable dental explorer, dental mirror, and a flash light. A total of 217 students aged 6 to 14 years were evaluated for their oral health status in Kamiran Town aspect of DMFT and DMFT in 2014. Fluoride concentrations were detected by IC. Data were analyzed using SPSS version 16 software. Ttest test was also used for analysis.Results: The results of this study showed that the DMFT mean in elementary school students for boys and girls were 4.76 and 6.20 respectively. The mean of DMFT for medium school students in boys and girls were 5.40 and 7.95 respectively. Moreover, the results of this study indicated that was significant between number of brush and DMFT and DMFT in elementary and medium school students (p<0.05). The concentration of fluoride in Kamiran Town water was 0.2 mg/l.Conclusion: The status of DMFT and DMFT among elementary and medium school students of Kamiran Town students was higher than the WHO standards and other area. Thus, to improve the current situation, a proper programming seems necessary. Furthermore, more attention must be paid to the education of families about dental and oral health.

Oral health is one of the most important sector of public and personal health. Information on oral hygiene starus regarding to DMFT (Decayed, Missed, Filled Teeth) as essential for pupils' heath education programs. This study was carried out to assess the dental health and to determine the relationship berween the pupil's DMFT and the use of toothbrush, the parents, literacy and family size. This study was conducted on 300 pupils studying in the city of Ahwaz. They were 120 girls and 180 boys. The study was cross sectional design and sudjects were chosen within a cluster random sampling. Data was collected using a questionnaire. Results showed the mean DMFT score of 1.98. Regular use of toothbrush among boys and girls was reported 7% and 14%respectively. No significant differences were found between use of toothbrush and dental decay with parent's litercay. However. There was a significant association DMFT score and number of children in the family (p = 0.007). In conclusion, oral hygiene status amoung pupils in this community is low and health education programs particularly for more at risk groups is recommended.
