Prior studies attribute this sidedness to compensations for hemispheric laterality. Patient's sex did not influence the magnitude of asymmetry, but patients with class II malocclusion exhibited significantly greater asymmetries, particularly in the anterior segment. Inspection suggests that this is attributable to the lack of coupling and guidance of the teeth between the jaws. There is a significant association between the severity of class II buccal-segment relationship and the extent of left-right asymmetries.<\/jats:p><jats:p>Conclusion: Clinically, these lateralities need to be anticipated, particularly in class II malocclusions, and incorporated into the treatment plan.<\/jats:p>","DOI":"10.2319\/081606-335","type":"journal-article","created":{"date-parts":[[2007,5,9]],"date-time":"2007-05-09T17:32:06Z","timestamp":1178731926000},"page":"779-786","source":"Crossref","is-referenced-by-count":9,"title":["Bilateral Asymmetry in the Tooth Relationships of Orthodontic Patients"],"prefix":"10.2319","volume":"77","author":[{"given":"Edward F.","family":"Harris","sequence":"first","affiliation":[{"name":"a Professor, Department of Orthodontics, University of Tennessee, Memphis"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katherine","family":"Bodford","sequence":"first","affiliation":[{"name":"b Resident, Department of Orthodontics, University of Tennessee, Memphis"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1164","reference":[{"key":"2020042117453342200_i0003-3219-077-05-0779-b1","doi-asserted-by":"crossref","first-page":"1859","DOI":"10.14219\/jada.archive.1943.0389","article-title":"Asymmetry of the face.","volume":"30","author":"Thompson","year":"1943","journal-title":"J Am Dent Assoc"},{"key":"2020042117453342200_i0003-3219-077-05-0779-b2","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1179\/bjo.2.1.37","article-title":"A radiographic study of facial asymmetry.","volume":"2","author":"Hewitt","year":"1975","journal-title":"Br J Orthod"},{"key":"2020042117453342200_i0003-3219-077-05-0779-b3","doi-asserted-by":"crossref","first-page":"1209","DOI":"10.1016\/S0028-3932(97)00166-8","article-title":"Facial asymmetry during emotional expression: gender, valence, and measurement technique.","volume":"36","author":"Borod","year":"1998","journal-title":"Neuropsychologia"},{"key":"2020042117453342200_i0003-3219-077-05-0779-b4","doi-asserted-by":"crossref","first-page":"489","DOI":"10.1016\/S0889-5406(94)70010-9","article-title":"Mandibular skeletal and dental asymmetry in class II subdivision malocclusions.","volume":"105","author":"Rose","year":"1994","journal-title":"Am J Orthod Dentofacial Orthop"},{"key":"2020042117453342200_i0003-3219-077-05-0779-b5","doi-asserted-by":"crossref","first-page":"435","DOI":"10.1016\/j.ajodo.2003.05.005","article-title":"Outcome measurement in the correction of mandibular asymmetry.","volume":"125","author":"Edler","year":"2004","journal-title":"Am J Orthod Dentofacial Orthop"},{"key":"2020042117453342200_i0003-3219-077-05-0779-b6","doi-asserted-by":"crossref","first-page":"151","DOI":"10.1037\/0022-3514.76.1.151","article-title":"Symmetry and perceived facial attractiveness: a monozygotic co-twin comparison.","volume":"76","author":"Mealey","year":"1999","journal-title":"J Pers Soc Psychol"},{"key":"2020042117453342200_i0003-3219-077-05-0779-b7","doi-asserted-by":"crossref","first-page":"199","DOI":"10.1146\/annurev.psych.57.102904.190208","article-title":"The evolutionary psychology of facial beauty.","volume":"57","author":"Rhodes","year":"2006","journal-title":"Annu Rev Psychol"},{"key":"2020042117453342200_i0003-3219-077-05-0779-b8","doi-asserted-by":"crossref","first-page":"766","DOI":"10.1016\/j.ajodo.2005.05.046","article-title":"Relationship between masticatory function and internal structure of the mandible based on computed tomography findings.","volume":"128","author":"Sato","year":"2005","journal-title":"Am J Orthod Dentofacial Orthop"},{"key":"2020042117453342200_i0003-3219-077-05-0779-b9","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/0002-9416(80)90037-8","article-title":"Early fracture of the mandibular condyles: frequently an unsuspected cause of growth disturbances.","volume":"78","author":"Proffit","year":"1980","journal-title":"Am J Orthod"},{"key":"2020042117453342200_i0003-3219-077-05-0779-b10","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1179\/bjo.13.1.1","article-title":"On the aetiology of malocclusion.
