Root Caries Incidence and Increment in the Population – A systematic review and meta-analysis of longitudinal studies
Objectives: Meta-analysis of root caries incidence and increment studies are rare. Two previous meta-analysis reported different estimates due to variations in inclusion criteria. More recent publications have also become available. This research aims to do a systematic review and meta-analysis of root caries incidence and increment with meta-regression to analyze the possible sources of heterogeneity.
Methods: A systematic review was conducted for publications in PUBMED and EMBASE. The inclusion criteria include longitudinal studies published in English language prior to 2017, observational population-based and clinical trial studies which presented data on root caries incidence and increment. The selected literature was independently reviewed by 2 authors based on the inclusion exclusion criteria for this systematic review. Data adjustment were performed by two authors independently for consistency checking. A pooled incidence and increment of root caries using decayed, filled root surfaces (DFS) were estimated. Additionally, a meta-regression analysis was performed separately by length of follow-up (<2 years; 2 years; 3-4 years and 5+years).
Results: Among 737 articles, 21 articles were included in the meta-analysis, 16 and 15 articles in the meta-analysis of incidence and increments respectively. For all included studies, the annualised root caries incidence and increment were 18.35% [CI=13.56%-23-14%] and 0.45 [CI=0.37-0.52] root DFS respectively. Length of follow-up time influenced the estimates. The annual root DFS incidence and increment from studies that less than 2 years were 32.95% [CI=29.13%-36.77] and 0.64 [CI=0.38-0.89] root surfaces respectively. In the studies with 5+ years follow-up, the cumulative annualised root caries incidence and increment were 9.4% [CI=3.32%-15.48%] and 0.43 [CI=0.21-0.64] root surfaces respectively. Type of studies (population-based vs clinical trials) did not influence the estimates.
Conclusions: Length of follow-up time is a factor influencing estimates of root caries incidence and increment. Root caries increased continuously in the older adults.
