Abstract
Introduction: Oral health status is one of the health-related priorities in Iran. The present study was conducted with the aim to systematically review the status of oral health in Iran using the decayed, missing, filled teeth (DMFT) index. Methods: In this meta-analysis, all data available on DMFT were reviewed and 35 published studies were included in the study based on search strategy. To estimate overall DMFT and perform the meta-analyses, Comprehensive Meta-Analysis (CMA) software was used. Results: Of all 876 articles, 35 were included in the study. A total of 21849 individuals were included in the meta-analysis. The overall DMFT index was 3.65 [95% confidence interval (CI), 3.01-4.34]. In addition, this rate was 2.30, 8.60, and 3.85 among children, adults, and children with mental/physical disabilities with (CI 95%, 1.76-2.95), (CI 95%, 6.10-9.60), and (CI 95, 2.98-4.80), respectively. Conclusion: Mean DMFT in the assessed published data was higher than that set forth by the World Health Organization (WHO). Further planning and taking effective preventive measures to improve the oral health status seems necessary.
Highlights
In this meta-analysis, all data available on DMFT were reviewed and 35 published studies were included in the study based on search strategy
This was a meta-analysis study and the required data were gathered searching for the key words “oral health, DMFT index, dental caries, decayed, missing, filled, teeth, epidemiology, prevalence, incidence, occurrence, Iran” in databases including PubMed, ScienceDirect, Iranmedex, Magiran, SIC, and Irandoc
The incidence of DMFT in the three studied groups of children, adults, and individuals with disabilities based on the random effect was determined to be 3.65 [95% confidence interval (CI), with lower and upper bounds of 3.01 and 4.34, respectively, Q = 2370.910, Degree of freedom = 38, P < 0.001]
Summary
Index of DMFT in Iran: A meta-analysis health issue in every country, which is highlighted by changing life styles and modernization.[4]. The present study was conducted with the aim to review all published data available on DMFT among the Iranian population, in addition to performing meta-analyses and reporting the results This was a meta-analysis study and the required data were gathered searching for the key words “oral health, DMFT index, dental caries, decayed, missing, filled, teeth, epidemiology, prevalence, incidence, occurrence, Iran” in databases including PubMed, ScienceDirect, Iranmedex, Magiran, SIC, and Irandoc. The searches returned 876 articles, and excluding the irrelevant items, or items repetitive between databases, with weak relevance to the study, or matching the exclusion criteria, 35 articles were entered in the study (Figure 1) These articles were read precisely, and the required data for the systematic review were inserted into the extraction table designed for Pournaghi-Azar, et al. The details of the reviewed studies are given in table 1
