Abstract
The current study was performed to establish a correlation between inclination of chewing surface of upper teeth respect to the orbital axis, TMJ pain and severity of idiopathic scoliosis. The study population was composed of 120 patients affected by idiopathic scoliosis and admitted for orthodontic evaluation and treatment between January 2008 and December 2009. Several variables were investigated: demographic (age and gender), TMJ pain, anatomic (left and right cuspid and molar tooth classes) and functional (inclination of chewing surface of upper teeth respect to the orbital axis) variables. TMJ pain was statistically associated to the inclination of chewing surface of upper left central incisor and the second upper right pre-molar. By grouping moderate and mild scoliosis, a statistical significant correlation was detected between more severe scoliosis and the inclination of chewing surface of several upper teeth (i.e. central and lateral left incisors, right canine and first pre-molar) respect to the orbital axis. Patients affected by severe idiopathic scoliosis have a specific pattern of inclination of chewing surface of upper teeth respect to the orbital axis. Globally, there is a correlation between inclination of chewing surface of upper teeth and TMJ painI documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
