Abstract
This study was performed to evaluate the relationship between the types of maxillary labial frenum attachment and the dental age in children. The maxillary labial frenum attachment levels were examined from the children who visited Chonbuk National University Dental Hospital between April, 2010 and December, 2013. The total number of the examined children was 320 (160 males, 160 females) between the age of 2 and 12. The types of maxillary labial frenum were categorized according to Placek's classification and each type was analyzed for its relationship with both Hellman's dental age and the eruption stage of permanent maxillary anterior teeth. The observed forms of maxillary labial frenum along with their frequency were as follows: gingival (56.3%), papillary (20.6%), mucosal (18.1%) and papillary penetrating (5.0%). The frenum form showed no significant difference due to gender (p > 0.05). From IC to IIIB in Hellman's dental age, the mucosal type increased significantly (p < 0.001). There was no significant relationship between the types of maxillary labial frenum attachment and the eruption state of permanent maxillary anterior teeth (p > 0.05).
본 연구는 어린이의 상순소대 부착위치에 따른 빈도와 치령과의 관련성을 평가하기 위한 목적으로 수행되었다. 2~12세의 어린이 320명을 대상으로 상순소대 부착위치를 조사하고, 이 결과와 Hellman의 교합 발육 단계 및 상악 영구 전치의 맹출 단계 간의 관계를 분석하였다. 그 결과 상순소대는 gingival type 56.3%, papillary type 20.6%, mucosal type 18.1% 그리고 papillary penetrating type 5.0%를 보였으며, 성별에 따른 유의한 차이는 없었다(p > 0.05). Hellman의 교합발육단계가 진행하면서 mucosal type이 유의하게 증가하였다(p < 0.001). 그리고 상악 전치가 맹출함에 따라 gingival type과 mucosal type은 증가하고 papillary type과 papillary penetrating type은 감소하는 경향을 보였으나 통계학적으로 유의하지 않았다(p > 0.05).
