Limited international evidence exists comparing how dental professionals diagnose and manage this condition in early childhood. This study aimed to compare the knowledge, diagnostic criteria, and clinical management of ankyloglossia among dental professionals in six countries and to assess whether shared diagnostic and management approaches exist for babies (\u22646 months) and infants (&gt;6 months). Methods: A multicountry cross-sectional study was conducted using a validated 27-item online questionnaire distributed between February 2023 and February 2025 to dental professionals in Spain, Italy, Portugal, Brazil, Ecuador, and Chile. Participants included paediatric dentists, oral surgeons, general dentists, and other dental specialists. Only fully completed questionnaires were analyzed. Primary outcomes included self-reported diagnostic practices, use of classification systems, and management strategies for ankyloglossia. Secondary outcomes included professional training, interdisciplinary collaboration, surgical techniques, and pain management practices. Results: A total of 1188 dental professionals participated. Overall, 80.7% reported routinely examining the lingual frenulum, while 42.4% used formal classification systems. Tongue mobility assessment was the most commonly reported diagnostic method, with significant variation across countries and professional groups (p &lt; 0.001). Specific training in diagnosis was reported by 67.2% of participants, whereas 50.6% reported treatment training, with marked inter-country differences (p &lt; 0.001). Surgical intervention was the most commonly reported management strategy (38.7%), particularly in babies \u2264 6 months, with frenotomy\/frenulotomy being the predominant procedure. Considerable variability was observed in surgical techniques, pain management, and recommendations for adjunctive therapies. Conclusions: Substantial international variability exists in the diagnosis, classification, and management of ankyloglossia among dental professionals. These findings highlight gaps in training and the absence of standardized, evidence-based clinical guidelines, underscoring the need for consensus-driven protocols to support consistent and multidisciplinary clinical care.<\/jats:p>","DOI":"10.3390\/dj14070436","type":"journal-article","created":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T05:32:01Z","timestamp":1784007121000},"page":"436","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["International Variability in the Diagnosis and Management of Ankyloglossia Among Dental Professionals: A Cross-Sectional Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1156-0743","authenticated-orcid":false,"given":"Elvira","family":"Ferr\u00e9s-Amat","sequence":"first","affiliation":[{"name":"Paediatric Dentistry Department, Faculty of Dentistry, Universitat Internacional de Catalunya, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-0719-5842","authenticated-orcid":false,"given":"Carlos","family":"Perez-Torres","sequence":"additional","affiliation":[{"name":"Paediatric Dentistry Department, Faculty of Dentistry, Universitat Internacional de Catalunya, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Carmela","family":"Giovannelli","sequence":"additional","affiliation":[{"name":"Paediatric Dentistry Department, Faculty of Dentistry, Universitat Internacional de Catalunya, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-3479-0244","authenticated-orcid":false,"given":"Ana","family":"Vall\u00e9s-Creixell","sequence":"additional","affiliation":[{"name":"Paediatric Dentistry Department, Faculty of Dentistry, Universitat Internacional de Catalunya, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9435-820X","authenticated-orcid":false,"given":"Constanza","family":"Sanchez-Davila","sequence":"additional","affiliation":[{"name":"Escuelas de Odontologia, Universidad San Francisco de Quito, Quito 170901, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulina","family":"Aliaga Sancho","sequence":"additional","affiliation":[{"name":"Escuelas de Odontologia, Universidad San Francisco de Quito, Quito 170901, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7518-2713","authenticated-orcid":false,"given":"Claudia Naranjo","family":"Camilla","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Universidad de los Andes, Santiago 12455, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4102-1719","authenticated-orcid":false,"given":"Ana Lu\u00edsa","family":"Costa","sequence":"additional","affiliation":[{"name":"Paediatric and Preventive Dentistry Institute, Faculty of Medicine, University of Coimbra, 3004-531 Coimbra, Portugal"},{"name":"Center for Innovation and Research in Oral Sciences, Faculty of Medicine, University of Coimbra, 3004-531 Coimbra, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5325-6929","authenticated-orcid":false,"given":"Ana Veloso","family":"Duran","sequence":"additional","affiliation":[{"name":"Paediatric Dentistry Department, Faculty of Dentistry, Universitat Internacional de Catalunya, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8714-8256","authenticated-orcid":false,"given":"Lluis","family":"Giner-Tarrida","sequence":"additional","affiliation":[{"name":"Dentistry Department, Faculty of Dentistry, Universitat Internacional de Catalunya, 08195 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3398-8679","authenticated-orcid":false,"given":"Francisco","family":"Guinot","sequence":"additional","affiliation":[{"name":"Paediatric Dentistry Department, Faculty of Dentistry, Universitat Internacional de Catalunya, 08195 Barcelona, Spain"},{"name":"Service of Pediatric Dentistry, Hospital HM Nens, HM Hospitales, 08009 Barcelona, Spain"},{"name":"HM Hospitals Health Research Institute, 28015 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Valderrama-Penagos, J.X., Rodr\u00edguez Alcal\u00e1, L., Plaza, G., Baptista, P., Garcia Iriarte, M.T., Correa, E.J., and O\u2019Connor-Reina, C.
