| Summary: | Introduction: Aesthetic facial animation is mostly reported to
be due to a close relationship between soft and hard tissue i.e.
dynamic smile with appropriate tooth proportions. But variations
in tooth size have been seen among various ethnic populations
globally.
Aim: To evaluate the size and morphology of maxillary anterior
teeth, the tooth with maximum variation both mesiodistally and
cervicoincisally. Also, the tooth to tooth ratio in percentage
of the mean tooth sizes in both genders in patients with
aesthetically acceptable smile decided by a panel in North
Indian population.
Materials and Methods: A total of 100 subjects (50 males
and 50 females) were taken and a video clip of their dynamic
smile was captured .The smiles were analyzed by a panel and
the tooth proportions of the selected attractive smiles were
evaluated in both males and females separately.
Statistical analysis: Data obtained was subjected to statistical
analysis using Microsoft Excel 2007 software; test used was
Unpaired t-test and also Mean ± S.D., Variance, Ratio of W/L
and its ranges were calculated. Significance is assessed at 5%
level of significance.
Results: The mesiodistal width and cervicoincisal length of maxillary
central incisor was greater compared to lateral incisor and canine
in both males and females. There was a statistically significant
difference between the width/length ratio of maxillary anterior teeth
between males and females.Canine and Lateral incisor showed
maximum variation mesio-distally and cervico-incisally.
Conclusion: A smile is more pleasing if the visible teeth are
in proper morphological proportions. Thus, it relates that teeth
play a vital role in increasing the attractiveness of a smile. The
mean coronal width/length ratio displayed a more square like
tooth form for both males and females. |
