ABSTRACT Introduction This study had twin objective first to determine the prevalence of dental caries and second to assess the correlation of duration of imprisonment, adverse habits and duration of adverse habits with dental caries status of prisoners in Central Jail, Jodhpur city, Rajasthan. Materials and methods This cross-sectional study was carried out on 131 male prisoners of Central Jail, Jodhpur city. A pre-designed questionnaire on general information, Tobacco consumption (frequency and duration of intake of Tobacco) and duration of imprisonment was used for the collection of data. The dental caries status was recorded using DMFT index (Henry T Klein, Knutson JW and Carole D Palmer; 1938). Results The total DMFT score was 180 and the average DMFT was 1.37 for the total prison population. A significant association was found between adverse habits and different age groups (χ2 = 16.77, p = 0.033) and between duration of adverse habits and different age groups of prisoners (χ2 = 16.58, p -value = 0.034). Significant correlation was found between adverse habit and duration of adverse habit (p < 0.05) in subjects having dental caries. Conclusion Though the prevalence of dental caries was so high, treatment for the same was not available due to lack of a dental unit in the jail. This highlights the urgent need of dental services in Central jail of Jodhpur city. How to cite this article Hans R, Thomas S, Dagli RJ, Solanki J, Arora G.

ABSTRACT Dental caries affect humans of all ages, including all regions of the world and is a disease of the complex interplay of social, behavioral, cultural, dietary, and biological risk factors. The objective of this study was to determine the oral hygiene status and the prevalence of decayed, missing, and filled number of teeth (DMFT index) among madrasa going children of selected area of Dhaka city, Bangladesh. A descriptive type of crosssectional study was conducted by a purposeful selection of some madrasa with a sample size of 251. Data collection were done by four sections. Section one, two and three consist of structured questionnaire and section four resembles to DMFT index which were measured by clinical examination using an examination form. Seventy percent of children had experienced dental caries with mean DMFT score of 1.94. Female children had higher DMFT score than male children. There was a highly significant association between tooth brushing frequency and family income of respondents with caries. We conducted this study in madrasa because up till now such study has not been performed. These data on oral health status and prevalence of DMFT will certainly helps to determine the appropriate treatment plan for madrasa going children. For the benefit of a community, dental health programs need to be conducted repeatedly in order to reach the goals of the World Health Organization (WHO).

In current forensic medicine practice, the need for the development of new, scientifically based approaches and methods of forensic medical identification is still very important. The number of left-handed people in the world varies from 5 to 30 %, and it can be useful in forensic practice. The possibility of establishing a dominating hand based on the intensity of dental caries (CFE - CARIES-FILLIN-EXTRACTION index) was studied. Taking into consideration the intensity of caries damage to the teeth on the right and left sides of right-handed, left-handed and ambidextras people, we offered and calculated the CFE difference index: «CFE on the right – CFE on the left». Significant differences in the CFE indexes can help to determine what hand has been predominant and it might be useful for forensic specialists.

Glucan Synthesis

Cariogenic bacteria, such as Streptococcus (S.) mutans and S. sobrinus, produce insoluble and sticky glucans as a biofilm material. The present study demonstrates that a lactic acid bacterium (LAB) named BM53-1 produces a substance that inhibits the sticky glucan synthesis. The BM53-1 strain was isolated from a flower of Actinidia polygama and identified as Lactobacillus reuteri. The substance that inhibits sticky glucan synthesis does not exhibit antibacterial activity against S. mutans. The cariogenic S. mutans produces glucans under the control of three glucosyltransferase (GTF) enzymes, named GtfB, GtfC, and GtfD. Although GtfB and GtfC produce insoluble glucans, GtfD forms soluble glucans. Through quantitative reverse-transcriptional (qRT)-PCR analysis, it was revealed that the BM53-1-derived glucan-production inhibitor (GI) enhances the transcriptions of gtfB and gtfC genes 2- to 7-fold at the early stage of cultivation. However, that of gtfD was not enhanced in the presence of the GI, indicating that the glucan stickiness produced by S. mutans was significantly weaker in the presence of the GI. Our result demonstrates that Lb. reuteri BM53-1 is useful to prevent dental caries.

Abstract Background Childhood dental caries can affect the children’s and their parents’ oral health-related quality of life. The aim of the present study was to evaluate the impact of oral and dental health conditions on the oral health-related quality of life in preschool children and their parents. Methods In this descriptive-analytical cross-sectional study, samples were selected from children 3 to 6 years old enrolled in licensed kindergartens using "proportional allocation" sampling. Then, the parents of the children were asked to complete the Early Childhood Oral Health Impact Scale (ECOHIS). Results In this study, 350 children aged 3 to 6 years were evaluated with a mean age of 4.73 years. The mean dmft index (decayed, missed, and filled teeth) was 3.94 ± 4.17. The mean score of oral health-related quality of life was 11.88 ± 6.9, which 9.36 ± 5.02 belongs to the impact on children and 2.52 ± 3.20 to parents' impact. Conclusions The mean score of ECOHIS increased with the dmft index increase in children, indicating a significant relationship between the dmft and ECOHIS score. These outcomes can be used as proper resources to develop preventive policies and promote oral health in young children.

The prevalence of dental caries and obesity is high as both raise significant health problems. The objective of this study was to evaluate the relationship between dental caries, the number of salivary colonies forming units of Mutans Streptococci (MS) and Lactobacillus (LB), and the nutritional status in a group of children from Transylvania. This observational study used a sample of 154 school children, aged 9 to 12 years. The prevalence of caries was measured using the decayed, missing, and filled teeth index for deciduous teeth (dmft index) and for permanent teeth (DMFT index). Height and weight were assessed for each subject, and their body mass index (BMI) percentile was calculated. Salivary levels of Mutans Streptococci (MS) and Lactobacillus (LB) were determined using the CRT Bacteria Test from Ivoclar Vivadent. In our study, we found a positive association between the BMI percentile, MS count, LB count, tooth brushing frequency, and the incidence of dental caries in children aged 9 to 12 years old. Future preventive programs should include nutrition control in order to prevent both the apparition of dental caries and obesity in children.

Objective: To evaluate the prevalence of dental caries in patients with cleft lip and/or palate and their cleft-free sibling controls. Methods: The two subject groups (patient and control) comprised 106 participants. The former group consisted of 53 patients with cleft lip and/or palate, aged 12 to 29 years, who visited the Oral and Maxillofacial Surgery Hospital at Damascus University of Syria. The control group consisted of the patients’ siblings who had no clefts, and they were sex matched to the patient group. Dental caries were examined clinically and were reported using the decayed, missing, and filled permanent teeth (DMFT) index. The DMFT scores were compared between the two groups. Results: The author found an overall association of dental caries with the presence of cleft lip and/or palate (odds ratio  =  2.52; 95% confidence interval  =  1.389–4.574; p < .05). The DMFT index scores were proportionally higher in patients with cleft lip and/or palate compared with the control group (p < .001). Conclusion: Subjects with cleft lip and palate are susceptible to dental caries independently of socioeconomic status.

Objective: To describe the experience and prevalence of dental caries in schoolchildren aged 6–12 years belonging to agricultural manual worker households. Material and Methods: A comparative cross-sectional study was conducted in two groups of schoolchildren: One considered “children of agricultural worker migrant parents” (n = 157) and the other “children of agricultural worker non-migrant parents” (n = 164). Epidemiological indices for dental caries were calculated for primary (dmft) and permanent (DMFT) dentitions, and compared in terms of age, sex, and the Simplified Oral Hygiene Index (SOHI). Two binary logistic regression models for caries prevalence in primary and permanent dentitions were generated in Stata. Results: For primary dentition, we observed the following dmft index: Non-migrants = 1.73 ± 2.18 vs. migrants = 1.68 ± 2.14. Additionally, we recorded the following caries prevalence: Non-migrants = 59.1% vs. migrants = 51.3%. For permanent dentition, we observed the following DMFT index: Non-migrants = 0.32 ± 0.81 vs. migrants = 0.29 ± 0.95. Further, we recorded the following caries prevalence: Non-migrants = 17.6% vs. migrants = 12.8%. No differences were observed for either dentition (p > 0.05) in caries indices and their components or in caries prevalence. When both caries indices (dmft and DMFT) were combined, the non-migrant group had a higher level of caries experience than the migrant group (p < 0.05). No relationship (p > 0.05) with migrant status was observed in either multivariate models of caries prevalence. However, age did exhibit an association (p < 0.05) with caries. Only the plaque component of SOHI was associated (p < 0.05) with caries in permanent dentition. Conclusions: Although over half of school children from agricultural manual worker households had caries in either or both dentitions and a considerable proportion were untreated lesions, the prevalence levels were somewhat lower than other reports from Mexico in similar age groups. No statistically significant differences were found in caries experience or prevalence in either dentition between non-migrant and migrant groups.

Aim: The main aim of this study was to Evaluate of Decayed, Missing and Filled Teeth (DMFT) Index in 12 Year Old Students of Tehran City, and to identify related factors that affect dental caries within this group. Methods: A cross-sectional survey was conducted among students of 12 years old in Tehran, Iran. Dental caries status was assessed in terms of decayed teeth (DT), filled teeth (FT) and decayed, missing and filled teeth (DMFT). “Data were analysed using SPSS version 22; a multivariate regression analysis was used to determine statistically significant associations between DMFT and other variables (p < 0.05). Results: A total of 416 respondents participated in the study. The mean age of the students was10.94 (SD=0.628) years, and the mean DMFT was 1.03 (SD=1.41). So that, in this study DT (0.53 ± 0.95) had the highest and MT (0.14 ± 0.47) had the lowest mean. A multivariate regression analysis model results showed a significant relation between high DMFT scores and such variables as increasing age, lower levels of mother's education, higher family income, lower frequency of tooth brushing and dental flossing, having a history of no visits to the dentist (P<0.05). Conclusion: The current study shows that Iranian female students have a poor oral health behavior, as very few subjects use dental floss on a regular basis. Although there appeared to be a significant relationship between caries scores and demographic factors such as age and socio-behavioral variables include  family income, the level of mothers' education, the frequency of dental brushing and flossing, and both the frequency and type of visit to a dentist.
