초록
Keratinized ginigva has clinical singificance in periodontal health because it plays important roles in resistance to mechanical trauma, to penetration of bacteria, and to tensional stress by muscle attachment. In order to investigate the width change of anterior keratinized gingvial during transitional period, the width of kerainized gingiva on anterior teeth was measured annually in elementary school children with deciduous dentition until the successive anterior teeth were completely erupted. The distance from the gingival margin on mid-portion of crown to mucogingival junction was measured by Boley gauge(Hu-Friedy, U.S.A.) and was recorded as the width of keratinized gingiva. The difference of the width of keratinized gingiva according to sex and dentition was analyzed statistically by Student t-test. Following results were obtained : 1. In deciduous dentition, it was shown that the width of keratinized gingiva on maxillary central incisors(
