Inclusion Criteria:  Participants will be recruited to the Orthodontic Clinic-Oral Health Clinic at the Department of Dentistry - University of Alberta based on the following inclusion criteria:  Males or females in the age group of 10-60 years old Individuals with permanent dentition Dental malocclusion with mild to moderate crowding Individuals undergoing CBCT imaging as part of Orthodontic diagnostic records Individuals in the age group of 10-60 years would have a full complement of permanent teeth erupted which will help standardize the research methodology to prevent an error in data acquisition, caused by the overlap of dental tissue in the mixed dentition period.  Exclusion Criteria:  Participants with missing permanent teeth, gingival recession (below CEJ), severe crowding, or a history of corrective orthodontics will be excluded. Any co-factors (previous orthodontic treatment) that might influence the ultrasound findings, will be excluded. Participants with unfavorable oral hygiene will be excluded due to the ambiguity associated with data acquisition in an inflamed periodontium. Also, participants presenting with craniofacial syndromes will be excluded due to the factors related to changes in craniofacial anatomy (maxilla-mandible anatomy)
