Comparison of the golden proportion value between the width of maxillary central incisors with the innercanthal distance of Malaysian Indians using golden mean gauge

Maxillary central incisors plays an important role in dental aesthetic because it is the widest anterior teeth, have large proportion when compared with adjacent anterior teeth and supports lip position until loss of both maxillary central incisors may affects asthetic. Loss of anterior teeths will affect the distance of mesiodistal width of anterior teeths and will loss guideline from width of anterior teeths. Innercanthal distance can be use as a guideline to get the width of maxillary central incisors with golden proportion. In year 1978, Levin found concept of golden proportion, the ratio between the width of maxillary central incisors and innercanthal distance is 0.618. Proportion of the width of the maxillary central incisors and innercanthal distance are influenced by the race and gender. The purpose of this study is to get a value of the golden proportion between innercanthal distance and width of the maxillary central incisors in Malaysian Indians aged 21-25 years. The study used a descriptive analytic method with cross-sectional design. The method of this study is the manufacture of study model with gypsum type IV from each subject. In the study model, the maxillary central incisors were measured at the most marginal ridge width from the right distal to the left of the teeth. Innercanthal distance measured from the inner corner of the left eye to the right. Measurements were made using golden mean gauge and digital calipers. The result shows the value of the golden proportion between innercanthal distance and maxillary central incisors in Malaysian Indians aged 21-25 years was 0.558 ± 0.021 and there is no significant relation value of the golden proportion between innercanthal distance and width of the maxillary central incisors between different sex and age. In summary, the value of the golden proportion between innercanthal distance and maxillary central incisors in Malaysian Indians aged 21-25 years was smaller than concept of the golden proportion 0.618.
