to determine the incidence of overeruption, rotation and tipping in unopposed
posterior teeth and study the association among temporomandibular disorders
(TMD). </span> </p> <p> </p> <p class="MsoNormal"> <span lang="en-us" xml:lang="en-us"> <b>Material
and Methods: </b> </span> <span lang="en-us" xml:lang="en-us">The study group consisted of 191 patients with
posterior tooth loss. These teeth (462 molars) overeruption, rotation and
tipping records were reviewed. </span> <span lang="en-us" xml:lang="en-us"> Tooth loss and
TMD symptoms were detected. In order to compare the variables Chi-square tests
and Fisher’s exact probability test were used. For TMD, Pearson correlation
prevalence parameters were used. </span> </p> <p> </p> <p class="MsoNormal"> <span lang="en-us" xml:lang="en-us"> <b>Results: </b> </span> <span lang="en-us" xml:lang="en-us">291 molars showed no
signs of overeruption. 119 molars showed slight, 52 molars had erupted moderate
to severe eruption. 184 molars had no signs of rotation, 203 were rotated less
than 15°, while 75 molars were rotated more than 15°. 274 molars showed no
signs of tipping whereas, 108 had tipping less than 15°, and 80 molars had
tipping of greater than 15°. Younger age group </span> <span lang="en-us" xml:lang="en-us"> </span> <span lang="en-us" xml:lang="en-us">and
female gender were found to be statistically significant regarding mean scores
of TMDs </span> <span lang="en-us" xml:lang="en-us">

  </span> <span lang="en-us" xml:lang="en-us">Molar
rotation was more frequent in the maxilla; whereas overeruption and tipping
were more common in the mandible Significant associations between the signs of
TMD and tooth loss were found, but the current results does not support the
concept that loss of molar support is an etiologic factor in TMDs.   <span style="font-size:11pt;"> </span> </span> </p> <p> </p> <p> </p>}, number={4}, publisher={DNT Ortadoğu Yayıncılık A.Ş.}
