A healthy diet and proper eating habits in childhood promote optimal oral health. This study aimed to evaluate dental caries and its association with feeding patterns in children referred to Bushehr dental centers in 2022.

This cross-sectional study was conducted on 178 children who referred to Bushehr dental centers in 1401. The DMFT index and the Persian version of the Food Frequency Questionnaire were used to check the tooth decay and the food pattern of children, respectively. A hierarchical linear regression model was used to investigate the relationship between tooth decay and food patterns; in this way, the variables affecting caries were placed in four blocks of demographic factors, behavioral factors, socio-economic factors, and the amount of food intake, so that by adjusting the effect of the first three blocks, the effect of the block of food intake in predicting the indices of dmft, DMFT and the sum of them (DMFT+dmft) could be checked.

The hierarchical linear regression results showed that in the final model, the value of the adjusted R2 for the DMFT, dmft indices and, the sum of them (DMFT+dmft) was 0.63, 0.98 and, 0.59, respectively. (p value < 0.001). Furthermore, the predictive role of the dietary pattern alone (R2 change) on DMFT, dmft, and DMFT+dmft indices was 0.30, 0.52 and, 0.45 respectively, which indicates a higher predictive role than behavioral, demographic and, socioeconomic factors.

The study found a confirmed relationship between tooth decay and feeding patterns. It was also observed that feeding patterns have the greatest impact on the decay of deciduous, permanent teeth, and both of them in children of this age group. Demographic characteristics, socioeconomic status of the family, and behavioral characteristics were respectively in the next levels and played a lesser role in the deterioration of these indicators.

 Dental anxiety is an obstacle to seeking dental care and is associated with poor oral and dental health outcomes. The present study aimed to determine the relationship between dental anxiety and socio-demographic factors of mothers with decay-missing-filled (DMF) index of children under 6 years old.

 This descriptive-analytic study included 173 pairs of childeren under 6 years old and their mothers, who were included in the study among the clients of the yazd Dental Faculty. Dental anxiety level were determined using the standard dental anxiety questionnaire (MDAS). Information on sociodemographic details and the mothers education level was recorded. caries prevalence of individuals was determined by decayed, missing, and filled teeth (DMFT) index. Intraoral examinations were done by the last-year educated dental student under the supervision of a pediatrician. Statistical analyses were performed using the one-way ANOVA, and pearson correlation analysis.

The average age of the children was 4.7±0.64 years, and 54.9% of them being boys. The majority of mothers (40.5%) had a university education. There was no statistically significant difference in the average maternal dental anxiety scores across different levels of dental caries in children. There was a weak positive correlation between the child's age, dmft index, and maternal dental anxiety (r=0.208, P=0.003).

Although no statistically significant relationship was found between maternal dental anxiety and children's deciduous teeth, considering the importance of maternal dental anxiety in the implementation of preventive oral health protocols, along with the characteristics of the child and family, maternal dental anxiety should be considered. This issue increases with the age of the children because older children had a higher dmft index.

 Vitamin D is a steroid hormone that is obtained primarily from exposure to sunlight, as well as from diet and supplements. This vitamin plays an important role in calcium phosphate homeostasis and bone turnover, and as a result, the musculoskeletal system. This vitamin is also effective in the immune system.

In this study we reviewed the related articles and books published in English between 2010 and 2023 in PubMed, Medline, and Google Scholar and searched the Scopus databases electronically using the keywords "vitamin D", "teeth", "oral manifestations", "Vitamin D deficiency" and "Dentistry".

 By reviewing related articles about the role of vitamin D in different structures of the body, including oral cavity, and the effects of its deficiency in the occurrence of diseases and the use of its supplements in the recovery of diseases, it seems  that this vitamin plays a significant role in the oral health and the immunity. There are conflicting results regarding the effect of vitamin D on external root resorption in orthodontics and Sjogren's syndrome. Hence, clinical trial studies are required for confirmation.

Background &

Dental anxiety is an effective factor in reducing children's dental visits. It is necessary to identify the factors involved in causing dental anxiety to promote public health. The purpose of this study was to evaluate the relationship between dental fear and anxiety in 5-10 -year -old children with dental caries and a history of trauma in Ardabil dental clinics in 2022.

247 children (139 girls and 108 boys) were examined in terms of demographic information, history of oral and dental trauma, and socio-economic status through a questionnaire. The dmft/DMFT index was determined using the clinical examination to check the oral health condition. Dental fear and anxiety were measured using two standard scales, FIS and CFSS-DS. Chi-square test was used for data analysis .

According to the FIS index, the prevalence of dental anxiety was 11.4% and according to the CFSS-DS questionnaire, it was 18.2%. Children aged 5-7 years showed more anxiety (p=0.043). Children who had a dental visit showed higher levels of anxiety based on the CFSS-DS index (p=0.002). According to the FIS index, children without a dental visit history had a higher frequency in the "very upset" group (p=0.009). Severe dental caries in permanent teeth (DMFT) were associated with a higher level of anxiety (p=0.028). No statistically significant relationship was found between gender, number of siblings, child's position in the family, parent’s education, family income level, history of trauma and dmft with dental anxiety.

The results of the present study showed that age, history of dental visits and decay of permanent teeth are effective factors on children's dental anxiety.

Identification of proximal caries is a major challenge faced by dentists. Bitewing radiograph is the method commonly used to detectproximal caries. Another methodincludes the use of magnification in digital bitewing radiograph. The aim of this study was to assess the efficacy of magnification on the diagnosis of proximal caries.

In this descriptive study 40 sound human molars and premolars were selected. Based on the gold standard, the cavities were prepared under contact point on one proximal surface of the tooth. Teeth were mounted and digital bitewing radiographs were taken and images were observed at magnifications 5x, 4x, 3x, 2x, 1x. Every tooth was assessed for caries on a 5 point scale. The data was analyzed by Cochrane-Q test.

There was a significant difference between the certain sensitivity of proximal caries diagnosis in digital radiography in groups with magnitudes 1, 2 and 3with magnitude 4 and 5 groups (p value= 0.04). However, between the probable sensitivity (p value= 0.298), definite NVP (p value= 0.496) and probable NVP (p value= 0.819), definite attribute (p value= 0.846) and probability (P) There was no significant difference in proximal caries diagnosis.

The accuracy in detecting proximal caries increases with a magnification increase and magnification 2x and 3x have the highest diagnostic accuracy but over increased magnification can reduce the accuracy on proximal caries diagnosis.

Considering that 67 to 90 percent of dental caries in the age of 5 to 17are related to occlusal surface on molars,the use of fissure sealant has been reported as effective in reducing caries. The aim of this study was to assess the clinical effectiveness of fissure sealants placed on permanent first molars between 2016 and 2018 in pediatric department of Dental Faculty, Tehran Medical Sciences , Islamic Azad University.

In this cross sectional descriptive study, the files of patients in whom the first permanent molars fissure sealant was performed by dental students during 2016 to 2018 were extracted and assessed. Before the evaluation, the teeth were cleaned using tooth brush and paste . Fissure sealant retention was evaluated with probe and dental mirror on a dental chair.Data were processed by SPSS25 statistical software and logistic regression model was used to determine the effect of variables.In this study, P<0.05 was considered significant.

In 160 fissure sealants done , Complete retention 20.6% (33 teeth), partially retention loss 43.8 % (70teeth) and complete retention loss was  35.6 % (57 teeth) .

It seems, more than half teeth , last fissure sealant retention during time, more than 68 percent have no caries.

Eating behavior in childhood has been implicated in the development of dental caries. Thus, the purpose of this study was to investigate the effect of problematic eating behavior and its association with early childhood caries (ECC) among 3-6 years-old children

This study was performed on 53 children with ECC (case group) and 53 children without ECC (control group). Clinical examination of children was performed to determine the caries indices. Subsequently, the parents of children in both groups were requested to complete the Childrenchr('39')s Eating Behavior Questionnaire (CEBQ). The statistical analysis was performed with SPSS 24. P-values less than 0.05 were considered statistically significant.

The mean age of the subjects in this study was 4.82±1.05 years. The results showed that the food responsiveness, enjoyment of food, emotional overeating, satiety responsiveness, slowness in Eating, emotional undereating and food fussiness were not significantly different between the two groups with ECC and without ECC. Also, based on the results, it was found that the desire for sugary drinks in the two groups was significantly different (P=0.002) as the tendency for sugary drinks was higher in the ECC group. There was a significant relationship between the dmft (r=0.33, p<0.001) and dmfs (r=0.35, p<0.001) indices and the desire for sugary drinks.

The present study showed that the desire for drink could been implicated in the development of early childhood caries. So that with increasing tendency to use sugary drinks, the dmft and dmfs level also increases.

Autism is a congenital neurological disorder characterized by impaired social interaction, communication, and behavior. Due to the special condition of these children and their inability to observe oral hygiene, patients depend on their caregivers. In this regard, the present study aimed to evaluate the clinical consequences of untreated dental caries based on the pufa/PUFA index in autistic children aged 6-12 years old In Isfahan.

This descriptive-analytical study was conducted on 90 children in autistic centers based on clinical examination. The examination was performed using a mirror, explores, and headlight. The pufa/PUFA checklist and severity of the autism were documented for each child. The data were analyzed in SPSS software using the Mann-Whitney U test.

The majority of children had mild autism. The mean of pufa and PUFA indices in the autistic children were obtained at 3.43±2.46 and 0.62±0.29, respectively. Among all the pufa/PUFA index parameters, the exposed pulp) was higher. In the current study, there was no significant difference between males and females in terms of autism severity (P=0.205). Moreover, the autism severity had no significant relationship with pufa/PUFA index in deciduous and permanent teeth (P>0.05).

The results of the current study pointed out that the rate of caries was relatively high in autistic children, and oral hygiene in primary dentition was worse than permanent dentition.

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.

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.

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).

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.

Dental anxiety and fear can act as a barrier to seek dental care leading to insufficient oral health in people. The aim of this study was to determine the relations between dental fear and anxiety with dental caries status (DMFT) and clinical consequences of untreated dental caries (PUFA) among the adult patients referred to the faculty dental clinic of Tehran University of Medical Sciences.

In this cross-sectional study in 2019, the patients above 18 years old were assessed. Two standard questionnaires, Dental Fear Scale (DFS) and Modified Dental Anxiety Scale (MDAS), were used to assess the scores of dental fear, and dental anxiety, respectively. The demographic data of the patients were recorded. Dental caries status and clinical consequences of untreated dental caries, using DMFT and PUFA, respectively, were measured. Pearson correlation coefficients and multiple linear regression model (Backward method) were used for statistical analysis.

Totally, 283 patients with the mean age of 38.6±11.8 years old participated. The mean scores of MDAS, and DFS were 12.04±4.49, and 41.33±16.87, respectively. Educational level (P=0.03, β=-0.14) and marital status (P=0.01, β=0.17) had significant relationships with MDAS scores. Moreover, a significant relationship was found between marital status and DFS scores (P<0.001, β=0.25). Significant correlations were found between dental anxiety level and D (P<0.001, r=0.36) and M components (P=0.02, r=0.14) of DMFT index. Moreover, there was a significant correlation between dental anxiety and U components of PUFA index (P=0.045, r=-0.12). Furthermore, the correlations between dental fear and D and M component of DMFT were significant (P<0.001, r=0.36; P<0.001, r=0.23; respectively).

Dental anxiety and dental fear were infrequent in the studied population; however, significant relationships were found between dental anxiety and dental fear with dental caries indices. Therefore, it was concluded that the more MDAS and DFS scores, the worse dental caries status.

Dental caries is a multi-factorial disease Demographic factors, also diet particularly breakfast  which  is an important meal are  factors affecting the level of dental caries. The purpose of this study was investigation  relationship between morning feeding and other demographic factors with  tooth decay in  9 years old Zahedan students

In This descriptive – analytical and cross-sectional study, Zahedan city  divided into four regions based on population table.From each region one public and private school (boy &girl), randomly selected,. for 400 boy& girl students  9 years old was filled the questionnaire about demographic factors, and   breakfast consumption  and oral examination was done for evaluation of  dmft, DMFT and OHI-s criterias by a dentist  . Data  were analyzed  with  soft ware  spss 21  and t-test , ANOVA and Pearson correlation..

The  Mean dmft, DMFT in children served breakfast (5.22±2.5 and 1.34±1.4 ( and in  children  did not consume breakfast (4.5±2.5 and 1.39±1.44) had no significant difference (p>0.05) but  the motherchr('39')s occupation and, father education had significant correlation  with DMFT and  mother  education had significant correlation with  DMFT,,dmft (P <0.05)

breakfast  consumption and its type  was not effective in reducing the level of dental caries. Children with educated mothers had  low permanent and  insidious dental caries and tooth decay  was significantly  lower in children with  employer or teacher  mothers and    educated fathers  .

To evaluate and compare salivary IL6 level in children with early childhood caries, before and 3 months after treatment.Materials &

In this study totally 32 children aged 3 to 6 years (12 without any caries, 10 with mild caries: 1 < dmft < 4, 10 with severe caries: dmft > 5) were included. Salivary samples were taken from all children at least 1 hour after eating food. The group with severe ECC were treated as a full-mouth rehabilitation under general anesthesia. The group with mild ECC were treated in clinic. Group with no ECC followed with no treatment. 3 months after full-mouth rehabalitation, salivary samples gathered again. Data analysis was performed using Kolmogorov-Smirnov, Wilcoxon, Kruskal Wallis tests with SPSS version 22 software.

Baseline IL6 was higher in patients with severe ECC (p value = 0.007 and P = 0.001) but there was no statistically significant difference in baseline levels between first two groups. (p value = 0.059). After treatment only severe ECC group had statistically significant difference ofsalivary IL6 after treatment. (p value = 0.007).

Our findings show that salivary IL6 level could be a partial predictor of ECC lesions. Treatment in sever ECC caused statistically significant decrease in IL6 but IL6 change was not significantin mild group.

Sense of coherence (SOC) is an effective factor in health-related behaviors. Mothers' SOC can influence health and consequently the orodental health-related quality of life (OHRQoL) in their children. The purpose of this study was to investigate the relationship between mother's SOC and OHRQoL in 3 to 5-year-old children in Sari, Iran. A total of 190 children, along with their mothers, were selected out of those referring to the Touba Clinic in Sari. The SOC of mothers was assessed by Antonovsky's SOC-13 questionnaire, and the OHRQoL was evaluated using the Early Childhood Oral Health Impact Scale (ECOHIS). The dmft index was also used to determine the status of dental caries in children. A p-value of In this study, the mean scores of SOC, ECOHIS, and dmft index were 57.13±4.9, 13.8±0.4, and 7.4±1.33, respectively. The dmft index correlated negatively with SOC (r=-0.453, P≤0.001) and positively with ECOHIS (r=0.535, P≤0.001). In this regard, with increasing the mean dmft in children, ECOHIS scores also increased, but SOC scores in mothers decreased. The ECOHIS also had a negative correlation with SOC (r=-0.347, P≤0.001); in other words, with increasing mothers' SOC scores, the scores of quality of life also decreased. Mothers' SOC significantly affected dental caries and quality of life in their children. Therefore, with the increase in maternal SOC, OHRQoL can be improved.

  Due to the high prevalence of dental caries and deficiency of vitamin D and conflicting results of studies, this study was conducted to assess the relationship of calcium (Ca) and vitamin D levels with dental caries in 6-12-year-old children. This cross-sectional study was conducted on 265 children with the age range of 6-12 years old admitted to Mofid Hospitaland need an evaluation of serum vitamin D and calcium level. The decayed, missing, and filled teeth index (DMFT) was recorded by a resident in pediatric dentistry. Vitamin D deficiency and inadequacy were defined less than 10 ng/ml and 10-30 ng/ml,25-hydroxyvitamin D, respectively. Ca deficiency was defined as serum Ca level less than 8.7 mg/dl. The overall prevalence of deficiency and insufficiency levels of serum vitamin D and deficiency levels of calcium were 68.67% and 2.6%, respectively. There were significant differences between the group with sufficient vitamin D and the group with insufficiency and deficiency of vitamin D in terms of the DMFT. However, among 6-8-year-old children, the D (P=0.009) and DMFT (P=0.03) levels were significantly lower in the group with sufficient level of vitamin D, compared to the group with insufficient and deficient levels of vitamin D. Moreover, no significant associations were observed between Ca levels and dental caries indexes. According to the obtained results, no significant associations of vitamin D and Ca levels were observed with dental caries among 6-12-year-old children.

Attention deficit-hyperactivity disorder (ADHD) is a persistent form of attention deficiency, hyperactivity and impulsivity, which is one of the most frequent mental health problems, affecting 12‒15 of children all over the world. The aim of this study was to investigate the rate of dental caries in children with symptoms of ADHD and to compare it with healthy children in order to emphasize the importance of prevention in preserving children's oral health.
In this case-control cross-sectional study, 33 children diagnosed with ADHD and medicated, 32 children diagnosed with ADHD but non-medicated and 37 healthy children, 7‒12 years of age, were investigated using DMF/dmft and PI parameters. The subjects were matched in terms of age and gender. Data were analyzed with SPSS 18 at a significance level of p value Children with ADHD are not able to carry out regular activities properly such as brushing their teeth due to attention deficiency and impulsivity. Therefore, the deciduous teeth of such children are more prone to dental caries compared to healthy children. In the age range evaluated in the present study, there were no differences in DMFT between the case and control groups. Moreover, dental plaque (PI) was the same in the healthy and hyperactive children.

Depression is one of the most prevalent diseases in the world, with a heavy socioeconomic burden on the society. Dental caries, too, is a prevalent disease and is related with many factors such as the socioeconomic and demographic statuses of the family. The aim of this study was to investigate the relationship between maternal depression and the child’s dental caries.
This analytical cross-sectional study was performed using two-step sampling in a dental clinic and a football school in Isfahan in summer, 2017. Ninety children under 12 years of age were examined to record the number of decayed, missing/extracted or filled deciduous (dmft) and permanent (DMFT) teeth. Their mothers were asked to answer Beck inventory for determining their depression score. The relationship between maternal depression and caries status was investigated using Pearson’s correlation coefficient, and the mean dmft and DMFT scores were compared among different levels of maternal depression using ANOVA, followed by post hoc Tukey tests (α = 0.05).
The mean depression score of mothers was 7.38 ± 2.41 and the means of dmft and DMFT were 2.89 ± 2.13 and 0.69 ± 1.03, respectively. An increase in the maternal depression score was correlated with a significant increase in dmft of children. The only significant item in comparison of dmft among maternal depression groups was a higher dmft in children who had mothers with 17‒30 score compared to the 0-10 score group.
There was a significant relationship between maternal depression and dmft and DMFT of children, and the relationship was stronger for deciduous teeth. Furthermore, mothers with higher levels of depression, who needed psychological consultation, had children with higher dmft.

Background and Dental caries is one of the most common chronic diseases in childhood. Parents have an important role in the control of caries in their children .The aim of present study was to assess of parents oral health behavior on Sic and plaque indices of their 7 years old children.
This cross-sectional study was conducted on 200 girls, first grade students in Kerman, Iran. Data were collected by questionnaire consist of demographic data and oral health behavior and clinical examination according to by WHO criteria and plaque index. T-test and regression were used to analyze data .P value at 0.05 was considered statistically significant.
89.5% of parents were mothers (179 people). The mean age of parents was 34.00 ± 6.33. 63% of fathers and 52.5% of mothers had university education. The mean of Sic and dmft indices were 6.29 ± 3.25 and 5.25 ± 3.27 respectively. The mean of plaque index in the one third of the population with highest dmft was 94.5313 ± 10.10731 and 90.8862 ± 12.54252 for the other two third. There was a significant difference between two groups (p=0.003). The mean score in oral health behavior with highest dmft was 6.87 ± 1.742 and 7.14 ±1.846. There was a statistically significant difference between these two groups. There was a significant correlation between mothers’ job and parents’ age with the oral health behavior of the children (p=0.008, p=0.050). There was a significant correlation between fathers’ job with their oral health behavior (p=0.020).
According to the study, the low level of education of parents, especially the mother and the habitat in the village, affect the oral health of children. Due to the young population of the country, planning for the prevention and treatment of children's oral teeth is essential

Due to the numerous side effects of synthetic analgesics, attention has been paid to find new analgesic agents with fewer side effects. This study aimed to evaluate the analgesic properties of Satureja bachtiarica essential oil in mice.
In this study, eighty male NMRI mice were randomly assigned to 5 groups including a control group, groups receiving Satureja bachtiarica essential oil at doses of 25, 50 and 100 mg/kg and a group that received morphine at a dose of 10 mg/kg. After intraperitoneal injection of morphine and essential oil, pain response was determined using hot plate and tail immersion tests.
In the hot plate test, 100 mg/kg of Satureja bachtiarica essential oil showed significant analgesic effect compared with the control group but, 50 and 25 mg/kg doses of essential oil did not show any significant effect. Intraperitoneal injection of Satureja bachtiarica essential oil at a dose of 100 mg/kg increased resistance to the hot water at 0, 2, 4 and 6 minutes after the beginning of the tail immersion test (P The results of this study showed the analgesic effect of Satureja bachtiarica essential oil on mice.

First molar has an important role at individual’s dental health. Among the known risk factors, the experience of previous caries is of the best predictors for future caries. The aim of this study was to examine the association of primary teeth caries and other risk factors with the incidence of permanent teeth caries by considering the caries extent and severity.
This case-control study was done on 150 students from second and third grade with 9 years old. Cases included children with at least one carious permanent molar. Caries-free students who were matched based on the gender and mother education was considered as control group. Examination was done on dental unit under the unit light with blunt explorer and mirror for visual assessment. DMFT, dmft and caries severity (D1-D3) were recorded based on WHO standards. Data were calculated using SPSS18, Correlation, Chi Square Analysis, Odds ratio and Logistic regression.
Linear correlation between dmft in primary teeth and DMFT in permanent molars was obtained with r:0.34 (P0.05).
Caries-free primary teeth predicts permanent teeth without decay with a high possibility. It could be helpful in caries risk assessments.
