The proportion of dentists who performed selective (SE) or stepwise (SW) carious tissue removal (% SW + SW). Wherever possible, subgroups of dentists (according to specialization like pedodontics [p] or endodontics [e], or in different countries) were separately entered into meta-analysis. The pooled proportion and 95 % confidence intervals (bold) from random-effects meta-analysis is shown as diamond. Heterogeneity was assessed using χ 2-test and I 2-statistics. Publication bias or small-study effects were evaluated using Egger’s regression intercept test as well as funnel plot analysis. n total sample size
