S. Linderaronson et al., NORMALIZATION OF INCISOR POSITION AFTER ADENOIDECTOMY, American journal of orthodontics and dentofacial orthopedics, 103(5), 1993, pp. 412-427
Changes in incisor inclination and position in both jaws of children d
uring the first 5 years after adenoidectomy were studied. The main cha
nge is a significant increased labial inclination of the incisors for
the adenoidectomy groups. All variables that measure the labiolingual
position of the mandibular incisors confirm a significant labial incis
or positioning for both sexes. Stepwise regression analysis shows that
41% to 44% of the incisor proclination after adenoidectomy is account
ed for by two regressors-sex (female) and increase in the sagittal siz
e of the nasopharynx. The study supports the hypothesis that a changed
mode of breathing after adenoidectomy is associated with significant
labial positioning of the incisor teeth.
