Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over past decade, three‐dimensional topographic data from microscopic regions tooth surfaces have been collected, and surface parameters published both extant fossil species. However, different types measurement instruments processing used by respective laboratories conducting DMTA limited potential comparison. In this study, we propose correction formulae produced to facilitate intercomparison. We six confocal five scan standard samples with strictly defined areas. found significant differences in parameter values among machines, despite scanning exact same spots. The degree discrepancy varied considerably, manufacturer similar models showing less variation. Some exhibited high correlations between instruments, enabling development regression equations formulae. Using these formulae, adjusted conducted meta‐analysis herbivores examine effects internal external abrasives. Our findings indicate overall positive abrasives on DMTA, varying responses ruminant non‐ruminant herbivores. supports hypothesis that ruminants effectively “wash ingesta” their rumens, mitigating impact reducing dental wear.
