An Analysis of Maxillary Anterior Teeth Crown Width-Height Ratios: A Photographic, Three-Dimensional, and Standardized Plaster Model’s Study

Table 7

Comparison of mean width height ratios of maxillary anterior teeth at different crown levels, paired -test analysis ().

Variables	Incisal third width and height ratio; % SD	value	Middle third width and height ratio; % SD	value	Cervical third width and height ratio; % SD	value
Right central incisor		0.001		0.001		0.001
Left central incisor
Right lateral incisor		0.001		0.001		0.001
Left lateral incisor
Right canine		0.296		0.001		0.001
Left canine

value less than 0.001; -value: it measures the size of the difference relative to the variation in sample data. The smaller the -value, the more similarity exists between the two sample sets, while a large -score indicates that the groups are different. SD: standard deviation.
