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.

Oral and dental health are crucial for nutrition intake, speech, and facial aesthetics. They also significantly influence individuals' physical, social, and psychological activities. This study aimed to determine the relationship between the Dental Caries Index (DMFT) and oral health-related quality of life.

This descriptive-analytical study was conducted on 61 patients (29 men and 32 women) aged 20-50 years who visited the Gorgan Dental School Clinic, Iran during 2019. The DMFT index, encompassing Decay (D), Missing (M), and Filled (F) teeth, was calculated. Quality of life was assessed using the 36-item DIDL (Dental Impact on Daily Living) questionnaire, which covers five domains: dental appearance and aesthetics, oral comfort, overall oral and dental function, eating limitations, and dental and jaw pain. Scores were categorized into three groups: dissatisfied (below 0), moderately satisfied (0 to 7), and satisfied (above 7).

The mean score for oral health-related quality of life was 5.14±0.229, indicating a relative level of satisfaction. Pearson's correlation coefficient between DMFT and oral health-related quality of life was -0.358, suggesting a significant inverse relationship between DMFT and quality of life (P<0.05). The mean DMFT score ranged from 0 to 28, with a mean of 9.36, and the most frequent scores were 7, 11, and 13, each accounting for 11.5% of the sample. The mean decay (D) score was 3.44, the mean missing (M) score was 1.98, and the mean filled (F) score was 3.93, with ranges of 0-12, 0-19, and 0-13, respectively.

The results of this study indicate an inverse impact of the Dental Caries Index on patients' quality of life. Oral health-related quality of life is a multifaceted construct that affects various aspects such as appearance, oral comfort, and eating limitations, which are critical components of overall quality of life and satisfaction.

Drug abuse can have harmful effects on the health of the body, especially oral health. The aim of this study was to investigate the oral manifestations of addicts in four maintenance centers in Tehran in 2017.

In this descriptive study, patients' demographic data were recorded in a questionniare, then oral and teeth were  clinically evaluated. Data were analyzed by chi square, Kruskal-Wallis, Mann U-Whitney and Spearman tests with a significance level of 0.05.

The study was performed on 392 addicted individuals. Among this population, 192 person (49%) were women and 200 person (51%) were men. The mean age was 34.9±9.4 years.  Methamphetamine & morphine were the most commonly used drug among women and men, respectively. At least one oral lesion was  present in 31% of women and 18% of men. The erythematous and spongy gingiva with round margin was the most frequent oral manifestation. There was a significant relationship between the duration of addiction withdrawal and all of the variables of color, consistancy, marginal contour and gingival tissue in men (p = 0.03). There was a positive correlation between DMFT index and duration of addiction in women  (p <0.001) and  men (P<0.05). About 75% of the subjects had dry mouth and dental attrition , which increased with the duration of addiction.

Methamphetamine & morphine were the most commonly used drug among women and men, respectively. Dry mouth, spongy and erythematosus gingiva were the most common oral lesions in the addicts.

Permanent first molars are susceptible to caries due to their particular anatomical form, early development and lack of knowledge of parents about their permanence. This study was conducted to determine the index of first permanent dental careis (DMF6) and some of its related factors in 12 year-old students.
This descriptive-analytical study was carried out on 400 students (200 females and 200 males) using combined method (stratified and cluster sampling) from public and non-governmental schools in Gorgan, northern Iran during 2015-16. First permanent molar examination was carried out. The parent's education level, frequency of toothbrushing and daily consumption of sugar-containing snack foods was recorded in a questionnaire. Each decayed, missing and filled first permanent molar tooth was given number one. These numbers were combined to compute the DMF6 index for each individual.
The DMF6 index was zero in 19.5% and the DMF6 index was determined to be between 1 and 4 in 80.5% of the children. The mean DMF6 index was 2.23±0.07 and significantly higher in girls (2.39±0.10) than in boys (2.07±0.11) (P Dental caries prevalence among 12-years-old students in north of Iran is higher (2.23) than global standard until 2020 (lower than 1). Gender of child, parent’s education, frequency of toothbrushing and consumption of sugar-containing snack foods plays an important role in the rate of dental caries.

Thalassemia major is one of the most prevalence congenital diseases in the world. This disease is wide spread in Iran and created some problems for health-care system. The aim of this study was to determine of situation oral health among thalassemic patients of Qazvin city in 2013.
In this descriptive - analytic study, thalassemic patients were selected with census method (n=60). Data were collected with examination, and interview. Questionnaire was include demographic, clinical and paraclinical information. Patients were examined and followed up by a dentist. DMFT index was determined on the basis of the examinations. Validity and reliability of the questionnaire was conducted. Data were analyzed by descriptive and analytic statistic tests with SPSS, version 16.
The majority of patients were female (%61.2) and had a history of blood transfusion (%67.3). The most of patients (%83.7) had no history of dental visit and most of them (%77.6) had no tooth brushing. The majority of patients had varying degrees of tooth decay. DMFT index was %57. The frequency of brushing and age had significantly effects on tooth decay (P Thalassemic patients have more problems in comparison other people. Diagnostic and therapeutic procedures have increased their survival. . Thus health indicators include oral and dental hygiene should improve in these patients specially.

Dental caries is the most common infectious and transmissible disease of the teeth. Significant Caries Index is one of the indices defined by WHO to identify individuals who have the highest DMFT (Decayed، Missing، Filled teeth). The aim of this study was to evaluate DMFT index and Significant Caries Index in 12-year-old male students in Sirjan. In this cross-sectional descriptive-analytical study seven hundred 12-year-old students from Sirjan، selected by systematic cluster-randomized sampling، were evaluated. Data were collected by examination and a questionnaire. The teeth were examined with a blunt-tip dental explorer، a dental mirror and illumination by torchlight. The questionnaire consisted of questions on parents’ educational level، birth rank of the student، number of children in family، toothbrushing frequency، fluoride use and dental visit status. Data were analyzed with SPSS 16 using t-test and one-way ANOVA (α = 0. 05). The mean of DMFT and SiC indices were 3. 56 ± 2. 34 and 6. 04 ± 1. 32، respectively. There were significant relationships between DMFT index and the number of children in the family (p value = 0. 016)، birth rank (p value = 0. 042)، toothbrushing frequency (p value = 0. 000) and fluoride use (p value = 0. 042). However، there were no significant relationships between DMFT index and parent’s educational level (p value = 0. 047) and dental visits (p value = 0. 198). The means of DMFT and SiC indices in 12-year-old students in Sirjan were higher than standards defined by WHO. Furthermore، the number of children in the family، birth rank، toothbrushing frequency and fluoride use had significant effects on dental caries in students.

Dental caries is the most prevalent chronic childhood disease that has a profound impact on the health of both the individual and community health. On the other، the overweight and underweight in children is a major public health concern influenced by common factors with dental caries. The aim of the present study was to assess the relationship between DMFT (Decay-Missing-Filled-permanent teeth) and anthropometry indices in 9-11 year old primary school children of the city of Shiraz، Iran-2012. The present cross-sectional study was conducted on primary school children، aged 9 to 11 years، selected by cluster random sampling in four areas of Shiraz city، in 2012. The prevalence of children with dental caries was calculated by measuring the number of teeth decayed، missing or filled duo to caries (DMFT) indices using the WHO screening standards. Weight، height، and sitting height were measured and body mass index (BMI) and leg height were calculated. The association between Anthropometry and DMFT were examined using bivariate correlation and linear regression tests by the SPSS software. The difference mean DMFT index between five groups of BMI was evaluated by ANOVA and post hoc Tukey tests. A total of 974 pupils were studied. Mean DMFT was 0. 94±1. 46. There were significant association between DMFT and BMI (r=-0/91; p=0/005). Mean DMFT was significantly reduced from underweight children to obese children (p=0/027). Underweight children have a higher risk of developing caries in their permanent teeth.

Age estimation in adults, over the age of 25 years, is a continuous forensic challenge. Before 24 years old, age estimation could be done based on resorbtion of primary teeth, developing permanent teeth and eruption of teeth. Demirgian's and Gustafson's Methods have also encountered problems. The aim of this study was age estimation by clinical examination and panoramic radiography using decayed, filled and missing teeth (DMF Index) in patients between 24-65 years old. This analytic descriptive study composed of 120 patients referred to dental clinic of Iran Petroleum Company. Decayed, filled and missing teeth were evaluated using panoramic radiography. Because of the limitations of radiographs in demonstrating decayed teeth, clinical examination was done too. Finally the relationship between chronological age and dependent variables evaluated using statically tools. Result of this study indicated that there is a direct relation between chronological age and all variables except filled teeth. This relation between age and missing teeth and DMF Index was high. Although, there is an acceptable relationship between chronological age and some variables, these are dependent in different factors like personal hygiene, individual circumstances, social, economical and cultural condition too; So, this method is not suitable for age estimation singly. But, it could be used as an adjunct method for age estimation.

Patients with thalassemia major needs more dental care due to their medically compromised condition. The aim of this study was to evaluate the dental health and dental treatment needs of these patients at Zahedan university school of Dentistry in 2009. m aterials and In this descriptive-analytical study, 75 patients with thalassemia major were selected in which 42 boys and 33 girls with mean age of 10.79±6.2 referred to community dentistry center as the case group and 75 patient's relatives referred to Zahedan school of Dentistry as the control group. Two groups matched for age and sex. The studied variables were patient's educational level and their parents, dental caries and treatment needs. Statistical analysis was carried out by chi-squared test and t-test. Thalassemic patient had increased average dental caries and missing (d=2.24, m=0.13, D=2.49, M=0.52) than the control group (d=2.13, m=0.05, D=0.97, M=0.35). Pulp therapy was the most needed treatment in patient group and in the other group filling dental caries was needed more. According to the high incidence of dental caries in patient with thalassemic major, effective preventive measures, health education and dental treatment are needed for this group.

The fluoride of water can increase the resistance of enamel of teeth against dental caries. In places with low fluoride level in potable water, dental caries is very high before puberty. The aim of this study was to determine the fluoride level of potable water of Ilam- Iran and it's relation to DMF criteria in workers of industrial city of Ilam. This study was done in fall of 1999 on the 320 workers which their age was between 20-34 (x ± SD:28.1 ± 1) years old by descriptive analytical method. The factories were selected by cluster sampling and workers were selected by random sampling from different socio-economic status. The mean concentration of fluoride in potable water was 0.28 mg/l which is lower the standard limit. The average value for DMF Index was 4.3 in workers. There was a significant negative correlation between fluoride control of potable water and number of DMF teeth (r=0.1, p= 0.01). The lowest value of DMF index was in range of 20-23 years old. When the fluoride content of water was higher, the dental caries was lower. The addition of fluoride to potable water to about 1mg/l, health educational programs and fortification of foods in Industrial regions and factories is recommended.
