Dental erosion · General population (children and adults) assessed for dental hard-tissue health
Among adults and excluding the outlier study, vegetarian diet was associated with higher odds of dental erosion with no heterogeneity (OR 2.56, 95% CI 1.77 to 3.71; ungraded).

Caries experience (mean DMFT) · General population (children and adults) assessed for dental hard-tissue health
Among adults, the lower DMFT score in vegetarians was smaller and not statistically significant (mean difference -0.09, 95% CI -0.32 to 0.13; ungraded).

Dental caries measures other than pooled DMFT (DMFS, decayed/filled surfaces and teeth, root caries, nonvisible lesions, white spots) · General population (children and adults) assessed for dental hard-tissue health
Evidence on other dental-caries measures was inconsistent: some indices (decayed surfaces/teeth, root caries, white spots) were higher in vegetarians while some studies found lower caries in vegetarian children (ungraded).

Caries development in permanent teeth · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)
Early-childhood oral hygiene and dietary habits show inconsistent associations with permanent-teeth caries, often losing significance after adjustment for past caries (2 studies; not pooled; not GRADE-rated).
