Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.
Intervention categories, outcome domains and clusters are a proposed key pending human validation. Clear all filters

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 Vegetarian diet and its possible influence on dental health: A systematic literature review. (2020) | 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 | Ungraded |

Vegetarian diet (any diet excluding all meat, poultry and fish) vs Nonvegetarian diet 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 Vegetarian diet and its possible influence on dental health: A systematic literature review.
