Vegetarian diet (any diet excluding all meat, poultry and fish) vs Nonvegetarian diet Number of natural teeth (missing/present teeth, edentulousness, MT component of DMFT) · General population (children and adults) assessed for dental hard-tissue health · Multiple countries (mostly India; also Finland and other European countries, Brazil, Trinidad and Tobago); community and clinical settings Evidence on the number of natural teeth was conflicting and could not be pooled (ungraded). Vegetarian diet and its possible influence on dental health: A systematic literature review. (2020) All outcomes | Seven studies reported on the number of teeth with conflicting findings; meta-analysis was not possible due to inconsistent outcome definitions. One study found vegetarians had significantly more teeth; two found no… | 7 studies | GRADE not reported |

Studies behind the findings
None of these reviews ties its included studies to this outcome in the data here. Cochrane reviews and reviews with headline outcomes only do not list their studies yet.
How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
