Determination of the Combined Width of Maxillary Anterior Teeth Using Innercanthal Distance With Respect to Age Gender and Ethinicity

Abstract

Objective: To evaluate the relationship between inner canthal distance and maxillary anterior teeth width withrespect to age, gender and ethnicity.
 Study Design: Cross sectional study.
 Place and Duration of Study: Altamash Institute of Dental Medicine, Karachi, from Aug 2019 to Jan 2020.
 Methodology: One hundred participants from both genders with full permanent dentition, no interdental space or pathology and facial symmetry were included in this study. The measurements were carried out with digital Vernier caliper. SPSS-25 was used for statistical analysis.
 Results: The mean ± SD of inner canthal distance and width of maxillary anterior teeth were 2.99cm ± 0.46and 3.82cm ± 0.35 respectively. A significant difference was found between gender (p=0.037) and inner canthaldistance. The maxillary anterior teeth width and inner canthal distance varies amongst different ethnicities(p=0.01). The inner canthal distance does not vary with advancing age (p=0.87) whereas width of maxillaryanterior teeth varies (p=0.04). A weak correlation value of 0.47 was found between inner canthal distance andmaxillary anterior teeth width.
 Conclusion: This research suggests that there is a weak relationship between inner canthal distance and maxillary anterior teeth width. Therefore, a multiplication ratio of 1.27 is advised to get combined mesiodistal width of maxillary anterior teeth. Additionally, the value of both differs in various local ethnicities. Inner canthal distance does not vary with age though has significant gender disparities while maxillary anterior teeth width remains constant.

Maxillary Anterior Teeth Dimensions and Relative Width Proportions: A Narrative Literature Review

“…The correlation with facial parameters is not always present and constant, and it strongly depends on the sample's ethnicity [15,17]. Correlation seems to be low, but significant for the inter-canthal distance, with the sum of the central incisors mesiodistal diameters or with the entire anterior group [18][19][20][21]. Regarding the inter-pupillary distance, there is no correlation between the dental dimensions in males and females [22], but in women, the inter-canine distance coincides with the inter-alar distance [22].…”

“…However, there is an important ethnic influence. Sample (n): 70 subjects from an Indian population Al Wazzan [18] 2001 In vitro study…”

Assessment of maxillary anterior teeth using RED proportion and golden proportion among adult young Gujarati individuals

“…2 For great Esthetics, Adequate size, shape, color, biotype, gingival zenith, smile line, minimized negative space; axial inclination graduation, incisal embrasure gradation, and gingival frame contour are essential for patient satisfaction in modern dentistry. 3,4 To achieve an well-organized balance between the aesthetic harmony of the face with the dentofacial structures, several guidelines are introduced. These guidelines are the foundation for aesthetic knowledge and are extensively followed by aesthetic, Prosthodontics and restorative practitioners worldwide.…”

Assessment of Golden Proportion among Natural Maxillary Anterior Teeth of Global Population: A Systematic Review

“…Dental aesthetics is one of the primary goals in oral rehabilitation, having a positive effect on the self-esteem and psychosocial wellbeing of patients [1,2]. In modern dentistry, esthetic outcomes have become increasingly critical for patient satisfaction, which comprises adequate size, shape, color, biotype, gingival zenith, smile line, minimized negative space, axial inclination graduation, incisal embrasure gradation, and gingival frame contour [2,3]. Several guidelines are introduced to achieve an organizational balance between the aesthetic harmony of the face with the dentofacial structures.…”
