The purpose of this study was to determine the prevalence of AOB in children and adolescents who visited a private dental hospital. In this study, subjects aged between 16 and 18 years with AOB were included. Data about orthodontic examination of patients were taken from preentered dental records of the hospital. Data of patients with AOB regarding age, gender, and intraoral and extraoral features were collected from the case records of the subjects, and statistical analysis was performed (Chi-square test and nonparametric correlations). The prevalence percentage of open bite in the anteriors was 2.7%, with more prevalence in Class 1 subjects (81.5%). Subjects with AOB had competent lips (81.8%), straight nasolabial angle (86.8%), and shallow palatal vault (49.5%). AOB had no significant relationship with the type of malocclusion, palatal vault, and lip competency, according to the Chi-square test. AOB and the nasolabial angle had a significant association. Both acute and right-angled nasolabial angles were commonly seen in adolescent patients with AOB. In children and adolescents visiting a private dental hospital in Chennai, the prevalence of AOB was found to be 2.7%. A significant association was observed between AOB and nasolabial angle.<\/jats:p>","DOI":"10.4103\/japtr.japtr_123_22","type":"journal-article","created":{"date-parts":[[2024,5,27]],"date-time":"2024-05-27T11:41:46Z","timestamp":1716810106000},"page":"S67-S71","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Assessment of anterior open bite prevalence in children visiting a dental hospital \u2013 A retrospective evaluation"],"prefix":"10.4103","volume":"13","author":[{"given":"K.","family":"Akshaya","sequence":"first","affiliation":[{"name":"Department of Dentofacial Orthopaedics, Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Science, Saveetha University, Chennai, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ravindra Kumar","family":"Jain","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Science, Saveetha University, Chennai, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arya S.","family":"Prasad","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Saveetha Dental College and Hospitals, Saveetha Institute of Medical and Technical Science, Saveetha University, Chennai, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2022,11,30]]},"reference":[{"key":"R1-20260225","doi-asserted-by":"crossref","first-page":"69","DOI":"10.3126\/ojn.v3i1.9286","article-title":"Orthodontic treatment of anterior dental open bite with drawbridge effect: A case report","volume":"3","author":"Shrestha","year":"2013","journal-title":"Orthod J Nepal"},{"key":"R2-20260225","doi-asserted-by":"crossref","first-page":"337","DOI":"10.1016\/0002-9416(64)90175-7","article-title":"Open-bite: Diagnosis and treatment","volume":"50","author":"Subtelny","year":"1964","journal-title":"Am J Orthod"},{"key":"R3-20260225","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1111\/j.1601-6343.2008.00411.x","article-title":"Treatment results and long-term stability of anterior open bite malocclusion","volume":"11","author":"Remmers","year":"2008","journal-title":"Orthod Craniofac Res"},{"key":"R4-20260225","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1179\/bjo.5.1.21","article-title":"A review of anterior open bite","volume":"5","author":"Mizrahi","year":"1978","journal-title":"Br J Orthod"},{"key":"R5-20260225","doi-asserted-by":"crossref","first-page":"289","DOI":"10.1093\/ejo\/3.4.289","article-title":"A classification of open bites","volume":"3","author":"Richardson","year":"1981","journal-title":"Eur J Orthod"},{"key":"R6-20260225","first-page":"151","article-title":"Etiological aspects of anterior open bite","volume":"60","author":"Stojanovic","year":"2007","journal-title":"Med Rev"},{"key":"R7-20260225","first-page":"263","article-title":"The proper perspective of open bite","volume":"42","author":"Gershater","year":"1972","journal-title":"Angle Orthod"},{"key":"R8-20260225","doi-asserted-by":"crossref","first-page":"522","DOI":"10.12968\/denu.2011.38.8.522","article-title":"Anterior open bite: Aetiology and management","volume":"38","author":"Sandler","year":"2011","journal-title":"Dent Update"},{"key":"R9-20260225","doi-asserted-by":"crossref","first-page":"235","DOI":"10.12968\/denu.2003.30.5.235","article-title":"The causes, diagnosis and treatment of anterior open bite","volume":"30","author":"Burford","year":"2003","journal-title":"Dent Update"},{"key":"R10-20260225","doi-asserted-by":"crossref","first-page":"91.","DOI":"10.1186\/s12903-016-0285-x","article-title":"Prevalence of and factors affecting malocclusion in primary dentition among children in Xi'an, China","volume":"16","author":"Zhou","year":"2016","journal-title":"BMC Oral Health"},{"issue":"2","key":"R11-20260225","first-page":"CD005515","article-title":"Orthodontic and orthopaedic treatment for anterior open bite in children","volume":"18","author":"Lentini-Oliveira","year":"2007","journal-title":"Cochrane Database Syst Rev."},{"key":"R12-20260225","doi-asserted-by":"crossref","first-page":"337","DOI":"10.1016\/0003-9969(93)90141-8","article-title":"Anterior tooth relations in Kenyan Africans","volume":"38","author":"Hassanali","year":"1993","journal-title":"Arch Oral Biol"},{"key":"R13-20260225","doi-asserted-by":"crossref","first-page":"81.","DOI":"10.4103\/2278-0203.186164","article-title":"Malocclusion and early orthodontic treatment requirements in the mixed dentitions of a population of Nigerian children","volume":"5","author":"Aikins","year":"2016","journal-title":"J Orthod Sci"},{"key":"R14-20260225","first-page":"249","article-title":"An orthodontic study of temporomandibular joint disorders.
