Full texts were assessed independently by two reviewers, with disagreements resolved through discussion or third\u2010reviewer adjudication. A pre\u2010piloted data charting form was used to extract study characteristics, oral health assessment methods, and key findings related to HG.

Across all studies, a total of 8630 participants were represented (range 1\u20137765; median 34.5). Periodontal status was clinically assessed in one study, which found significantly worse periodontal indices in HG compared with controls, and one additional study reported higher self\u2010reported gum disease in individuals with HG. Dental cavities were self\u2010reported in one study, showing higher pre\u2010 and post\u2010pregnancy prevalence among those with HG. Three studies described hypersalivation consistent with ptyalism gravidarum, frequently co\u2010occurring with HG, while salivary biomarkers were assessed in two studies. One study reported enamel hypoplasia in children born to mothers with severe HG. Self\u2010reported oral hygiene difficulties were described in six studies, and one study noted higher levels of self\u2010reported temporomandibular joint disorder in HG participants.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This scoping review identifies a substantial gap in evidence linking HG with oral health conditions. Available studies suggest challenges in maintaining oral hygiene practices, alongside frequent gastric acid exposure, which might heighten risk for oral complications, but robust clinical data are lacking. Further research and interdisciplinary attention are needed to clarify and address these associations.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ijgo.70958","type":"journal-article","created":{"date-parts":[[2026,4,1]],"date-time":"2026-04-01T06:58:56Z","timestamp":1775026736000},"page":"48-55","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Hyperemesis gravidarum and oral health: A scoping review"],"prefix":"10.1002","volume":"175","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9421-5392","authenticated-orcid":false,"given":"Niamh","family":"Coffey","sequence":"first","affiliation":[{"name":"School of Dentistry Royal College of Surgeons in Ireland  Dublin Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucy","family":"James","sequence":"additional","affiliation":[{"name":"School of Medicine Royal College of Surgeons in Ireland  Dublin Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8438-1506","authenticated-orcid":false,"given":"Angela C.","family":"Flynn","sequence":"additional","affiliation":[{"name":"School of Population Health Royal College of Surgeons in Ireland  Dublin Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3610-3816","authenticated-orcid":false,"given":"Zeinab","family":"El\u2010Dirani","sequence":"additional","affiliation":[{"name":"School of Population Health Royal College of Surgeons in Ireland  Dublin Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9177-3505","authenticated-orcid":false,"given":"Shahnawaz","family":"Khijmatgar","sequence":"additional","affiliation":[{"name":"School of Dentistry Royal College of Surgeons in Ireland  Dublin Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,3,31]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2021.09.004"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2008.07.003"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0314783"},{"key":"e_1_2_10_5_1","first-page":"1","volume-title":"Clinical Guidelines for Dental Erosion","author":"O'Sullivan E","year":"2021"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000433007.16843.10"},{"key":"e_1_2_10_7_1","unstructured":"DentArtistry hyperemesis gravidarum consequences in teeth and dental treatment.https:\/\/www.dent\u2010artistry.com\/en\/hyperemesis\u2010gravidarum\u2010consequences\u2010in\u2010teeth\u2010and\u2010dental\u2010treatment\/"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1080\/17474124.2021.1890030"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm12196161"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/idj.12072"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.3390\/foods14030373"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.7326\/M18-0850"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.4328\/ACAM.20526"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.4103\/ejgd.ejgd_184_19"},{"issue":"9","key":"e_1_2_10_15_1","first-page":"573","article-title":"Characteristics and outcomes of ptyalism gravidarum","volume":"20","author":"Bronshtein M","year":"2018","journal-title":"Israel Med Assoc J"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.autneu.2016.07.005"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1080\/00029157.2015.1013186"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00404-012-2614-x"},{"issue":"6","key":"e_1_2_10_19_1","first-page":"303","article-title":"Ptyalism gravidarum","volume":"1","author":"Suzuki S","year":"2009","journal-title":"N Am J Med Sci"},{"issue":"9","key":"e_1_2_10_20_1","first-page":"704","article-title":"Evaluation and management of sialorrhea of pregnancy with concomitant hyperemesis","volume":"86","author":"Freeman JJ","year":"1994","journal-title":"J Natl Med Assoc"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1098-108X(199909)26:2<223::AID-EAT13>3.0.CO;2-Q"},{"key":"e_1_2_10_22_1","first-page":"561","article-title":"Clinical study of enamel hypoplasia and its causes.
