목적: 상악 전치부에 대한 심미적 요소들에 대하여 조사하고 남녀 간 차이 및 개인 심미적 인식도와의 연관성이 있는 지에 대해 분석하고자 한다. 대상 및 방법: 치주적으로 건강한 25 - 35세의 전남대학교 치의학전문대학원생 70명을 대상으로 상악 모형을 제작하였고 디지털 카메라를 이용하여 표준화된 사진을 촬영하고 계측 프로그램을 이용하여 상악 전치의 근 원심 최대 시각적 폭경과 치은 정점의 수직적 위치, 중절치의 최대 높이를 계측하였고 중절치의 치관 형태를 분류하였다. 참가자들의 심미 인식도 평가를 위해 설문조사를 시행하였다. 통계분석은 SPSS program을 이용하여 시행하였다. 결과: 상악 전치 시각적 폭경 비율의 경우 우측은 1.38:1:0.78, 좌측은 1.41:1:0.81의 평균값을 가졌고 황금 비율과는 차이가 있었다. 중절치관의 폭경 대 장경 비율의 경우 우측은 0.84, 좌측은 0.83의 평균값을 가졌다. 치은 정점의 위치의 경우 중절치는 원심측, 측절치는 중심, 견치는 원심측에 주로 위치하였다. 상악 전치부 시각적 폭경 비율, 중절치 폭경 대 장경 비율, 치은 정점 위치, 치관 형태, 미소시 치은 노출 정도는 남녀 간 차이가 없었고 이런 요소들과 안모의 형태와 참가자들의 심미적 인식도와는 관련성이 없었다. 결론: 참가자들은 상악 전치 시각적 폭경의 황금비율 및 중절치 치관의 이상적 폭경 대 장경 비율과는 일치하지 않았지만 상악 전치부 심미성에 대한 만족도가 높았다. 심미적 인식은 참가자들의 수치화된 객관적 지표보다는 주관적 판단이 더 중요함을 알 수 있었다.

Purpose: This research is to investigate factors that affect dental aesthetics and analyze whether individual perception affects and difference of genders affects the esthetic factors. Materials and methods: Seventy dental students of Chonnam University aged from 25 to 35 years old without periodontal problems were included. Maxillary dental cast for participants were made, and standardized photo was taken with a digital camera. Maximum visual width and the position of gingival zenith of maxillary anterior teeth and maximum height of the maxillary central incisors were measured by a measurement program and the shape of central incisor was categorized. Questionnaire was conducted to evaluate esthetic perception. SPSS program was used to perform statistical analysis. Results: The average visual width ratio of right maxillary anteriors was 1.38:1:0.78 and 1.41:1:0.81 for the left which differ from the golden ratio. The width to height ratio for right and left central incisor was 0.84 and 0.83 respectively. The gingival zenith position was determined to be: mostly, central incisors and canines were located in the distal side, lateral incisors were located in the center. The visual width ratio of right maxillary anterior teeth, ratio of width to height of central incisor, gingival zenith position, crown morphology and amounts of gingival exposure upon smiling were not significantly different between genders, and facial patterns and these dental esthetic factors were not related to aesthetic perception. Conclusion: Even though participants had the visual width ratio of maxillary anteriors or ideal width to ideal height of central incisors that did not agree with the golden ratio, they had high satisfaction for dental esthetics. Esthetic perception depends more on subjective judgements of participants than objective indices.
