The research was carried out on a cross\u2010sectional basis. The average age at eruption of permanent teeth, excluding third molars, was given as the mean (\u00b1\u00a0SD) and median in months for each gender. A table of percentiles of the eruption time was also determined.<\/jats:p><jats:p><jats:bold>Results.\u2002<\/jats:bold> The results show that, with the exception of the maxillary second premolars, the average age at eruption of permanent teeth in girls is less than in boys. The results also show that mandibular teeth have an earlier eruption time than maxillary teeth in both boys and girls. By the age of 96\u00a0months, 97% of the girls had all their first permanent molars. In boys, the corresponding age was 99\u00a0months. Amongst girls, maxillary canines erupt earlier than maxillary second premolars.<\/jats:p><jats:p><jats:bold>Conclusion.\u2002<\/jats:bold> On average, girls have their permanent teeth erupt earlier than boys. The sequence of eruption differs between girls and boys for maxillary canines and maxillary second premolars.<\/jats:p>","DOI":"10.1111\/j.1365-263x.2004.00586.x","type":"journal-article","created":{"date-parts":[[2004,12,26]],"date-time":"2004-12-26T14:53:06Z","timestamp":1104072786000},"page":"432-438","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["An epidemiological survey of the time and sequence of eruption of permanent teeth in 4\u201315\u2010year\u2010olds in Tehran, Iran"],"prefix":"10.1111","volume":"14","author":[{"given":"M.","family":"MOSLEMI","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,11]]},"reference":[{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.3109\/00016359109005930"},{"key":"e_1_2_8_3_2","volume-title":"Pediatric Dentistry: Scientific Foundations and Clinical Practice","author":"Stewart R","year":"1982"},{"key":"e_1_2_8_4_2","volume-title":"Paediatric Dentistry \u2013 A Clinical Approach.","author":"Koch G","year":"2001"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1080\/03014467500000661"},{"key":"e_1_2_8_6_2","first-page":"100","article-title":"Eruption of permanent teeth in malnourished children","volume":"40","author":"Triratana T","year":"1990","journal-title":"J Dent Association Thai"},{"key":"e_1_2_8_7_2","volume-title":"Dentistry for the Child and Adolescent","author":"McDonald R","year":"1994"},{"key":"e_1_2_8_8_2","volume-title":"Developmental Basis of Occlusion and Malocclusion","author":"Nanda SK","year":"1983"},{"key":"e_1_2_8_9_2","first-page":"217","article-title":"Time and order of eruption of primary teeth","volume":"13","author":"Lysell L","year":"1962","journal-title":"Odontology Revy"},{"key":"e_1_2_8_10_2","volume-title":"Oral Health Surveys: Basic Methods","author":"World Health Organization.","year":"1987"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1177\/00220345650440031201"},{"key":"e_1_2_8_12_2","volume-title":"Orthodontics, Development of the Dentition and Occlusion","author":"Moyers RE","year":"1994"}],"container-title":["International Journal of Paediatric Dentistry"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1365-263X.2004.00586.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1365-263X.2004.00586.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,15]],"date-time":"2023-10-15T03:56:37Z","timestamp":1697342197000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1365-263X.2004.00586.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,11]]},"references-count":11,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2004,11]]}},"alternative-id":["10.1111\/j.1365-263X.2004.00586.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1365-263x.2004.00586.x","archive":["Portico"],"relation":{},"ISSN":["0960-7439","1365-263X"],"issn-type":[{"value":"0960-7439","type":"print"},{"value":"1365-263X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004,11]]},"assertion":[{"value":"2004-11-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
