Oral manifestations arising from oral piercings: A systematic review and meta-analyses.

ABSTRACT

OBJECTIVE: The aim of this study was to perform a systematic review of oral manifestations arising from oral piercings. STUDY DESIGN: Literature was searched through January 2022 in PubMed, Scopus, Embase, Web of Science, Cochrane Library and Virtual Health Library, OpenGrey, and Google Scholar to address the question, "Is there an association between oral piercings and oral alterations, complications, or lesions?" Quality was assessed using the Joanna Briggs Institute appraisal tools. Meta-analyses were performed, and certainty of evidence was assessed through Grading of Recommendations Assessment, Development and Evaluation (GRADE). Reporting followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Fifty-four studies were included, with 15 achieving good methodological quality. Periodontal and tooth damage were the most reported, followed by soft tissue/mucosal injuries, speech disorders, chewing, soft plaque, and saliva. Pain was the most reported complication, followed by infection, swelling, bleeding, inflammation, allergy, and adornment aspiration. Meta-analyses revealed that 33% of participants with piercings had gingival recession (GR) (event rate [ER] = 0.329). In participants with piercings, ER values for nonspecified dental damage (NSDD), tooth chipping, wear/abrasion, and dental fracture (DF) were 27% (ER = 0.270), 22% (ER = 0.219), 34% (ER = 0.344), and 34% (ER = 0.338), respectively. Certainty of evidence was very low. CONCLUSIONS: Alterations, complications, and lesions were associated with oral piercings and adornments, of which GR, DF, and NSDD were the most prevalent.
