Dental caries in primary and permanent teeth in children's worldwide, 1995 to 2019: a systematic review and meta-analysis

Background: Early childhood caries (ECC) is a type of dental caries in the teeth of infants and children that is represented as one of the most prevalent dental problems in this period. Various studies have reported different types of prevalence of dental caries in primary and permanent teeth in children worldwide. However, there has been no comprehensive study to summarize the results of these studies in general, so this study aimed to determine the prevalence of dental caries in primary and permanent teeth in children in different continents of the world during a systematic review and meta-analysis. Methods: In this review study, articles were extracted by searching in the national and international databases of SID, MagIran, IranMedex, IranDoc, Cochrane, Embase, ScienceDirect, Scopus, PubMed, and Web of Science (ISI) between 1995 and December 2019. Random effects model was used for analysis and heterogeneity of studies was evaluated by using the I2 index. Data were analyzed by using the Comprehensive Meta-Analysis (Version 2) software. Findings: In this study, a total of 164 articles (81 articles on the prevalence of dental caries in primary teeth and 83 articles on the prevalence of dental caries in permanent teeth) were entered the meta-analysis. The prevalence of dental caries in primary teeth in children in the world with a sample size of 80,405 was 46.2% (95% CI: 41.6–50.8%), and the prevalence of dental caries in permanent teeth in children in the world with a sample size of 1,454,871 was 53.8% (95% CI: 50–57.5%). Regarding the heterogeneity on the basis of meta-regression analysis, there was a significant difference in the prevalence of dental caries in primary and permanent teeth in children in different continents of the world. With increasing the sample size and the year of study, dental caries in primary teeth increased and in permanent teeth decreased. Conclusion: The results of this study showed that the prevalence of primary and permanent dental caries in children in the world was found to be high. Therefore, appropriate strategies should be implemented to improve the aforementioned situation and to troubleshoot and monitor at all levels by providing feedback to hospitals

Methods: Retrospective cross-sectional study by reviewing medical records of patients with type 2 diabetes mellitus and laboratory studies from Hospital Information System at King Abdul-Aziz Medical City, National Guard, Riyadh – Saudi Arabia using predesigned sheet for data collection. Results: Among 352 patients enrolled in the study, 176 (50%) patients were from the family medicine setting and 176 (50%) patients were from the hospital setting. The mean glycosylated hemoglobin for the whole study population was 8.97±1.87. There was no significant difference between the two groups in regard to level of control (9.01±1.75 in the family medicine setting compared to 8.93±1.98 in the hospital setting). No significant correlation was found between level of control and age, duration of disease and number of follow-up visits in both settings. Conclusion: Patients with type 2 diabetes mellitus in this study were found to be poorly controlled in both the settings, diabetic clinic under family medicine and diabetic clinic under endocrinology. More research should be done to explore quality of care in a family medicine setting for patients with type 2 diabetes mellitus, as such a setting is expected to be more accessible, more convenient, and more cost effective to patients.
