Type of Study/Design
Systematic review with meta-analysis.
Subjects or Study Selection
Four electronic databases (PubMed, EMBASE, Web of Science, and CINAHL) were searched for experimental or observational studies in adults or children pertinent to the association between following a vegetarian diet and oral health, tooth disease, periodontal disease, or gingival disease. Selection criteria were not articulated, yet are presumed to include studies a) comparing subjects following a vegetarian versus a nonvegetarian diet, and b) measuring noncarious cervical lesions (NCCL), dental caries, and tooth loss.
Key Study Factor
Subjects following any type of vegetarian diet void of meat, poultry, or fish were compared with subjects following nonvegetarian diets that included meat, poultry, or fish.
Main Outcome Measure
Three oral health outcomes of interest were investigated: 1) NCCL, including dental erosion, abrasion, and cervical buccal defects, 2) caries defined as decayed, missing, or filled teeth or surfaces or the presence of dental caries, lesions, or white spots, and 3) the number missing or present teeth or edentulousness.
