Abstract

INTRODUCTION: A harmonious smile combined with a careful physical appearance is predominant in improving the psychosocial interaction of individuals. The success of oral rehabilitation is not based only on rigid concepts and previously established, but on harmonious relationship between the determinants of smile (teeth, gingival architecture and lip frame), don’t forgetting the lines operating in the composition dentofacial and facial. PURPOSE: The aim of this clinical study is to examine objective smile parameters during spontaneous smile, quantifying its prevalence in the total sample and by gender (female and male). The statistically significant differences were observed between men and women. METHODS: Standardized intraoral and extraoral photographs were taken in 62 adults. The following parameters were analyzed: correlation of dental and facial midline; upper lip curvature; relationship of the maxillary anterior incisal curve with the lower lip; smile line; width smile (number of teeth displayed in a smile) and shape of the upper incisors. Subsequently, a statistical analysis of the data was performed using the chisquare test. RESULTS: The simple frequency distribution of the variables revealed that a coincidence of the dental midline with facial midline, a anterior incisal curve paralell to the lower lip; an average smile line, a upward smile; smile width to the second premolar and square shape of the central incisors are most prevalent in the total sample. As to gender was obtained statistical significance for the smile line. High smile is more prevalent in women and low smile in men. CONCLUSION: There are statistically significant differences in the smile line between men and women. The outcomes of this study allow to identify the fundamental esthetic parameters in natural smiles to establish guidelines that helps the clinicians in esthetic analysis, individualized treatment planning and helps to perform dental restorations more naturals and individualized as possible.
