Methods: A convenience sample of 722 children aged 7\u20139 years attending one urban elementary school was examined at baseline, with follow\u2010up examinations at one and two years. Coronal surfaces of permanent first molars were scored with regard to caries experience and sealant status. Results: Among sound occlusal surfaces at baseline, 21 percent of upper and 25 percent of lower surfaces developed caries during the two\u2010year interval. In teeth that erupted between baseline and the first follow\u2010up exam, over 10 percent of occlusal surfaces developed caries. Pit and fissure caries accounted for 93 percent of all new carious surfaces, while sealants had been placed on 16 percent of occlusal surfaces during the study. Conclusions: Recognizing the limitations of this convenience sample, dental sealants should be used more widely in this Korean population, and should be applied soon after tooth eruption.<\/jats:p>","DOI":"10.1111\/j.1752-7325.2001.tb03376.x","type":"journal-article","created":{"date-parts":[[2007,5,1]],"date-time":"2007-05-01T07:45:29Z","timestamp":1178005529000},"page":"120-122","source":"Crossref","is-referenced-by-count":7,"title":["A Two\u2010year Longitudinal Study of Dental Caries in Permanent First Molars of Korean Elementary Schoolchildren"],"prefix":"10.1111","volume":"61","author":[{"given":"Bon\u2010Kyoung","family":"Cho","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ho\u2010Keun","family":"Kwon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kwon\u2010Soo","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young\u2010Nam","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel J.","family":"Caplan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,5]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"119","article-title":"Caries prevention.
