Participants' background information including birth characteristics, prenatal and early childhood exposures, family socioeconomic status and medical records was prospectively collected. Clinical examination of tooth emergence was conducted in 2010. Children were divided into complete emergence (of 28 permanent teeth) and partial emergence groups based on clinical examinations. Bivariate analyses were used to assess the association of tooth emergence status with each putative predictor. Unadjusted and adjusted logistic regression models were applied to select the best predictors for tooth emergence status at age 12.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Complete background information and clinical data were available from 514 children (76.9% of the invited participants). Bivariate analyses showed that the average birthweight in the partial emergence group was significantly lower than the complete emergence group (mean difference 0.2 kg, <jats:italic>P<\/jats:italic> = 0.006). The finding was confirmed by logistic regression analyses. In the adjusted regression model, it was found that for every 1 kilogram increase in birthweight, the odds of having partial emergence would be lowered by 0.49 (odds ratio 0.49, <jats:italic>P<\/jats:italic> = 0.006).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Birthweight is associated with status of permanent tooth emergence at 12 years of age, as observed from a population\u2010representative sample of Hong Kong children.<\/jats:p><\/jats:sec>","DOI":"10.1111\/cdoe.12236","type":"journal-article","created":{"date-parts":[[2016,4,26]],"date-time":"2016-04-26T21:52:10Z","timestamp":1461707530000},"page":"467-475","source":"Crossref","is-referenced-by-count":9,"title":["A population survey of early factors associated with permanent tooth emergence: findings from a prospective cohort study"],"prefix":"10.1111","volume":"44","author":[{"given":"Hai Ming","family":"Wong","sequence":"first","affiliation":[{"name":"Paediatric Dentistry &amp; Orthodontics Faculty of Dentistry The University of Hong Kong Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Si\u2010Min","family":"Peng","sequence":"additional","affiliation":[{"name":"Paediatric Dentistry &amp; Orthodontics Faculty of Dentistry The University of Hong Kong Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi Feng","family":"Wen","sequence":"additional","affiliation":[{"name":"Paediatric Dentistry &amp; Orthodontics Faculty of Dentistry The University of Hong Kong Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Colman P.J.","family":"McGrath","sequence":"additional","affiliation":[{"name":"Periodontology &amp; Dental Public Health Faculty of Dentistry The University of Hong Kong  Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,4,25]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0096-6347(41)90413-1"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0185(199606)245:2<374::AID-AR18>3.0.CO;2-M"},{"key":"e_1_2_7_4_1","first-page":"Article ID 3419","article-title":"Mechanism of human tooth eruption: review article including a new theory for future studies on the eruption process","volume":"2014","author":"Kj\u00e6r I","year":"2014","journal-title":"Scientifica (Cairo)"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/154405910808700509"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2003.10.031"},{"key":"e_1_2_7_7_1","first-page":"121","article-title":"The relationship between birth weight, birth height, and dental development by Demirjian's method","volume":"2","author":"Anbiaee N","year":"2013","journal-title":"JDMT"},{"key":"e_1_2_7_8_1","first-page":"10","article-title":"Up\u2010to\u2010date standards of permanent tooth eruption in Romanian children","volume":"2011","author":"Ogodescu A","year":"2011","journal-title":"Jurnalul Pediatrului"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00784-003-0228-1"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajpa.21258"},{"key":"e_1_2_7_11_1","volume-title":"Wheeler's dental anatomy, physiology and occlusion","author":"Nelson S","year":"2009"},{"key":"e_1_2_7_12_1","first-page":"81","article-title":"Delayed tooth eruption","volume":"1","author":"Peedikayil F","year":"2011","journal-title":"J Dent"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.4103\/2278-9626.112306"},{"key":"e_1_2_7_14_1","first-page":"63","article-title":"Eruption time of permanent teeth in Pakistani children","volume":"40","author":"Khan N","year":"2011","journal-title":"Iran J Public Health"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/205950"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1186\/1472-6831-13-15"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1136\/fn.83.2.F104"},{"key":"e_1_2_7_18_1","first-page":"30","article-title":"Delayed tooth formation in low birthweight African\u2010American children","volume":"15","author":"Harris E","year":"1993","journal-title":"Pediatr Dent"},{"key":"e_1_2_7_19_1","first-page":"67","article-title":"Factors influencing permanent teeth eruption.
