Regional caries data availability in Saudi Arabia: Impact of socioeconomic factors and research potential

摘要

Background and aimsMonitoring oral diseases is needed to allocate resources, plan health services and train dental workforce. Caries is one of the oral diseases most commonly included in oral health surveillance systems. The present study assessed (1) caries data availability in the administrative regions of Saudi Arabia and (2) factors associated with this availability.MethodsWe collected caries data in the period 2008–2018 in Saudi Arabia (outcome variable). The explanatory variables included region-level factors: (a) socio-economic indicators (percentage of individuals with university education, percentage of category A governorates, percentage of owned houses, households with computers, internet and smart phones) and, (b) oral health research potential indicators (number of Dental Public Health (DPH) specialists, Ministry of Health (MoH) dentist to population ratio and number of dental schools). ArcGIS was used for data visualization and logistic regression was used for analysis.ResultsTwenty-two studies provided caries data for 46.2% of the regions which were inhabited by 84.7% of the population. Region-level data availability was associated with the number of dental schools (OR?=?1.63) with 61.5% of the regions correctly classified. More regions were correctly classified when population to MoH dentist ratio (76.9%) and the number of DPH specialists (92.3%) were included.ConclusionsCaries data were available for half of the administrative regions in Saudi Arabia and data availability was associated with higher number of dental schools. The presence of DPH specialist provided the critical mass to collect caries data.
