Purpose:
The aim of this study was to compare the difference of dental arch and palatal morphology between children with impacted maxillary canine and without impacted maxillary canine, to provide reference for early diagnosis and treatment of impacted maxillary canine.
Methods:
Sixty-two children, 8-11 years of age (9.8±1.04 years), were divided into experimental group and control group, with 31 children in each group. Digital casts were obtained using 3D laser scanner from maxillary models. Dental arch width, length, basal bone width, palatal width, height, surface area and volume were measured. Paired t test was performed with SPSS 24.0 software package.
Results:
Dental arch width and palatal width were significantly narrower in experimental group than in control group(P<0.05), but there was on significant difference in dental arch length, basal bone width and palatal height between the two groups(P>0.05).Additionally, palatal surface area and volume were significantly larger in control group than in experimental group(P<0.05).
Conclusions:
Children with impacted maxillary canine have smaller maxillary dental arch width, palatal width, palatal surface area and volume compared to control group. Dental arch width, palatal width, palatal surface area and volume should be taken into consideration when early identifying impacted maxillary canine.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
