“…Hatice Ozdemir et al performed a study which concluded that all facial measurements, except the intercommisural width (ICW) and interpupillary width (IPW) in women and intermedial canthus width (MCW) in men, had significant effect on the CW according to multiple linear regression analysis [2]. George Attokaran et al(2018) performed a study which showed a high significant co-relation between interalar distance and the mesiodistal width of the six maxillary anterior teeth in both males and females [3].…”

Aims: To compare the width of the central incisor obtained by the given formulae with the actual width of the central incisor in males and females and assess whether the interpupillary , interalar ,intercommisural and interlateral canthus widths are reliable anthropometric measurements to give an accurate value of the width of the central incisor in local population. Study Design: Original Research. Place and Duration of Study: Department Of Prosthodontics and Crown and Bridge, Dr. D. Y. Patil Dental College and Hospital, Pimpri, Pune. Dr. D. Y. Patil Vidyapeeth, Pune – 411018, between June 2009 and July 2010. Methodology: A total of 160 participants [Males=80; Females=80] were selected in the age group of 18-25 yrs which fulfilled the selection criteria. Informed consent was obtained from each student before participation. The following anthropometric measurements were performed: CW which is the mesiodistal width of the maxillary central incisor, interpupillary width (IPW) and the interalar width (IAW), intercommisural width (ICW) and interlateral canthus width (LCW) which were calculated using a digital vernier calliper. The differences and variables were studied by sex and the differences in the expected mesiodistal width of the central incisor by IPW/CW=6.6 and CW=IAW/4 with the real value was evaluated. The values were evaluated and the differences helped in determining whether these anthropometric measurements can be used as a guide for selection of artificial teeth in males and females in local population. Results: As per this study conducted, in males & females there was statistically significant correlation between the width of the central incisors (CI) and the interalar width IAW (P value =0.043) and the interpupillary width IPW (P value =0.003) when calculated by formula CI=IAW/4 and CI=IPW/6.6. There was no statistically significant correlation between the width of the central incisor and the interlateral canthus width (LCW) and the intercommisural width (ICW). Conclusion: There was significant correlation between the interalar width and interpupillary width and the width of the central incisor. Thus, interalar width, when divided by 4, and the interpupillary width when divided by 6.6 was a reliable predictor of the selection of the maxillary central incisor width in females and males in local population.

“…This distance also varies by sex and ethnicity. The IAW is estimated to average 4 times the width of the maxillary central incisor (CW = IAW/4) [2,3].…”

“…There are other reports which show statistically signifi cant correlation between these two measurements. [29][30][31] Interalar width has been thus used extensively to select maxillary teeth in artifi cial prostheses. 29,[31][32][33] By and large, this hypothesis was rejected in current study for normal population (p<0.001).…”

Introduction: Facial proportion and dental proportions are matters of interest for dental professionals to craft a beautiful smile. In facial analyses, the role of different proportions cannot be overlooked when planning dento facial treatment. This study aims to determine the different facial proportions; smile index, lower smile index, nose width to outer inter commissural width, intercanine width to outerinter commissural width, nose width to intercanine width and outer intercommissural width to lower facial height in esthetically pleasing smile (ES) and esthetically unpleasing smile (US) groups. Materials and methods: The frontal smiling photographs (N=152, 74 pleasing and 78 unpleasing smile) were gathered and different linear measurements were carried out using digital ruler. The facial proportions were derived and comparisons were made amongst groups and differences were examined in comparison to standard accepted proportion (such as Golden proportion). Results: Average smile index of ES (5.899±1.201) was lower than that of US group (6.421±1.675).The golden proportion was not valid for smile indices in each group. Mean nose width to intercanine width ratio significantly differed in ES and US. The outer inter commissural width to lower facial height was not statistically significantly different from 1:1 ratio. Conclusion: Most facial proportions in pleasing and unpleasing smiles showed no difference. The outer intercommissural width to lower facial height was found in 1:1 proportion current study with possible utilization in determining vertical dimension of occlusion.

“…However, the literature does not agree on this topic: More recently, Wang's systematic review with meta-analysis [15] reported that within the 23 studies analyzed, there were no differences in the size of right and left incisors. Width and length also appear greater in men than in women [15,16]. Ethnicity is an influencing factor: The Caucasian population shows larger W, L, and W/L ratio than the Asian population, but there is also a great variability within the same populations [15].…”

Predictable results in the aesthetic treatment of anterior teeth can be obtained by resorting to the concept of dental aesthetics and, in particular, defining the ideal tooth dimensions and proportions to obtain a harmonious smile. Considering the great variety of articles dealing with the topic, and the lack of updated reviews, this narrative literature review aims to evaluate current knowledge on anterior teeth dimensions and to verify the existence and the potential applications of the anterior teeth proportioning theories (Golden Proportion, Golden Percentage, RED Proportion, and Golden Rectangle). PubMed, Embase, Cochrane Library, and Google Scholar databases were comprehensively searched using different keywords and term combinations. The research includes articles published up to June 2023, no time limits were set, and only articles in English were included. Inclusion criteria comprehended reviews, clinical studies, and in-vitro studies. A total of 66 articles were selected. Two main topics were identified: “Anterior teeth dimensions”, “Golden Proportions, Golden Percentage, RED Proportions, and Golden Rectangle”. As far as tooth dimensions are concerned, different width ranges are recognized for men and women and for different ethnic groups. Perfectly symmetric contralateral elements are found in low percentages of subjects. The correlation between dental dimensions and facial parameters is not always present, and it strongly depends on the sample’s ethnicity and gender. Ideal tooth proportions were only partially identified.
