Abstract
Background: Tooth decay and periodontal disease are the most common chronic human and oral diseases, respectively, and bacterial plaque has a major role in their occurrence. Because of the importance of plaque control, this study was done to compare the antimicrobial effects of Nigella sativa nanoparticles and chlorhexidine emulsion on the most common dental cariogenicic bacteria.
Methods: In this experimental study, the effects of 0.2% chlorhexidine mouthwash and Nigella sativa nanoparticle with different dilutions on Streptococcus mutans, Streptococcus sobrinus, Streptococcus salivarius, Lactobacillus acidophilus, Minococcal fecalis, and Enterococcus fecalis were compared using minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) assessment. Data were analyzed by SPSS Version 16.0 software, and statistical tests, including an independent sample t test.
Results: Mean diameters of growth inhibition zone because of the nanoemulsion of Nigella sativa nanoparticle was close to each other in different bacteria (p=0.665). In addition, there was no significant difference between these values because of different dilutions of nanoemulsion even in different microbial species (p=0.778). The MIC and lethal concentrations of Nigella sativa nanoemulsion were similar for Enterococcus faecalis and Streptococcus mutans, and it was higher than other bacteria. In comparison, the MIC and MBC values of all bacteria in chlorhexidine were lower than those of the nanoemulsion.
Conclusion: MIC and MBC values showed that Nigella sativa nanoemulsion affects tooth cariogenicic bacteria. Enterococcus faecalis and Lactobacillus acidophilus were the most resistant and susceptible bacteria to this nanoparticle, respectively, while the antimicrobial effects of Nigella sativa nanoemulsion were weaker than the chlorhexidine mouthwash.

Abstract
Background: The prevalence of dental caries among the elderly is high worldwide, and dental caries cause the major burden of oral diseases. This meta-analysis aimed to determine the dental caries experience among the elderly in Iran.
Methods: A systematic review of the published and grey literature on Iranians aged 65 years or older was performed. Six international and local databases provided the most comprehensive population-based studies. National oral health surveys and national disease and health surveys were considered other primary data sources. The quality of remained studies was assessed by a modified tool designed based on the STROBE statement checklist to evaluate the cross-sectional studies. R Version 3.6.0 was used for statistical analysis. Heterogeneity was assessed using Cochran’s Q and F statistics. Subgroup analysis was performed to detect the source of heterogeneity. Funnel plots and Egger’s regression intercept test were used to assess publication bias and selective reporting.
Results: Overall, 3099 sources were found. After excluding ineligible studies, 46 data points with 10411 people ≥65 years were included in the meta-analysis. The mean pooled decayed, missing, and filled teeth (DMFT) among older people was 26.84 (range, 26.41-27.28). The DMFT was 26.78 (range, 26.12-27.43) in women and 26.91 (range, 26.32-27.50) in men. The mean number of decayed teeth was 1.48 (range, 1.32-1.65). The mean pooled missing teeth was 24.83 (range, 24.20-25.46), and the mean pooled filled teeth was 0.14 (range, 0.12-0.17). The majority (92%) of the DMFT was related to missing teeth.
Conclusion: Iranian elderly have almost 5 sound teeth in their mouth on average. The Iranian oral health policymakers should address this considerable burden of dental caries in designing and implementing better oral health policies for the population, especially older Iranian adults.

Abstract
Background: Dental caries is a serious health condition in children. Poor diet, poor oral hygiene, and unique anatomy of the primary teeth can all contribute to the development of caries in primary teeth. Developmental structural defects in teeth during the fetal period and the first year after birth are believed to increase caries susceptibility. This study aimed to assess the correlation of the Apgar score with dental caries in 3- to 5-year-old Iranian children.
Methods: This retrospective, descriptive, cross-sectional study was conducted at the Pediatric Dental Clinic of Tehran Dental School in 2022. A total of 123 eligible children between 3-5 years were enrolled. The parents were requested to fill out a checklist regarding the information of demographics, birth and infancy condition and Apgar score of children. The children underwent clinical dental examination, and their dmft was recorded. Data were analyzed by the Pearson and regression tests. P values < 0.1 were considered statistically significant.
Results: The Pearson test showed that the 1-minute (P = 0.000) and 5-minute (P = 0.000) Apgar scores had a significant correlation with dmft. The regression analysis of demographic and birth factors revealed significant correlations between duration of breastfeeding (P = 0.066) and age of initiation of toothbrushing (P = 0.019) with dmft. Also, birth weight (P = 0.026) and mother’s educational level (P = 0.090) had significant correlations with the Apgar score.
Conclusion: The results indicated a significant correlation between the Apgar score and dental caries. Thus, newborns with lower Apgar scores are recommended to receive more regular oral and dental care services.
