Publication A systematic review and meta-analysis of primary teeth caries studies in Gulf Cooperation Council States(2018) Alayyan, Wafa; Al Halabi, Manal; Hussein, Iyad; Hassan Khamis, Amar; Kowash, Mawlood B.Objectives: The aim of the study was to evaluate the prevalence and severity of dental caries in pre-school children in the Gulf Cooperation Council (GCC) area. Methods: A search of literature was conducted to identify articles of dental caries in primary dentitions published during the period from January 1st, 1992 to June 30th, 2016. PubMed, Google Scholar search, and hand searching of journals was conducted to identify relevant articles. The search strategy employed both dental subject headings and free-text terms. Results: Out of a total of 193 studies that fit the initial inclusion criteria, 159 studies were further excluded. Only 34 studies were included in the systematic review and meta-analyses. The overall mean dmft in the primary teeth was 5.14 with prevalence of 80.9% in the GCC area. A high level of heterogeneity in the selected studies was found as demonstrated by Q-value of 2538.501 (df= 21) and I2 value of 99.17%. However, the funnel plots showed symmetrical shape at the bottom in both dmft and prevalence studies indicating absence of publication bias, which was also confirmed by insignificant result of Egger’s regression statistical test (Egger’s test P= 0.179–0.358). Conclusion: Caries in the primary dentition in the GCC States was high both in terms of mean dmft (5.14) and prevalence (80.95%).Publication A Systematic Review and Meta-analysis of School Children's Caries Studies in Gulf Cooperation Council States(2017-09-18) Alayyan, Wafa; El-Halabi, Manal; Hussein, Iyad; Hassan Khamis, Amar; Kowash, Mawlood B.Objectives: The aim of the present study was to evaluate the prevalence and severity of dental caries school children in the Gulf Cooperation Council (GCC) area, to help the development of systematic approaches for preventive oral care programs in the GCC states and to provide sound information for oral health promotion and public health care. Materials and Methods: A comprehensive search to identify both published and unpublished articles concerning relevant studies of dental caries in children aged 6–16 years for their permanent teeth published from 1992 to 2016 with no language and time limit was performed. The search strategies employed electronic databases and incorporated both dental subject headings and free text term. Results: The overall mean decayed, missing and filled teeth in the permanent teeth was 2.57, and the prevalence was 64.7% in the GCC area. Conclusions: Most of the studies were conducted in the Kingdom of Saudi Arabia. The results may not be a true reflection, and other countries in GCC are urged to study the prevalence and severity of caries in their children population.
